Description: TECHNICAL FIELD [Detailed description of the invention]

【0001】

[Technical field to which the invention belongs]

The present invention relates to an advertising method and an advertisement receiving device through a network, and more particularly to an advertising method through a wireless communication network and a wireless communication terminal for embodying the advertising method.

【0002】

[Conventional technology]

In general, a product provider conducts non-personal information provision activities, that is, advertisements, for sales promotion or corporate public relations for his / her products. Traditionally, TV, radio, newspapers, magazines, etc. have been widely used as advertising media, but recently, with the development of the Internet, banner advertisements and insert advertisements on Internet contents have also been widely used. In particular, SMS advertisements that utilize the short message service (hereinafter abbreviated as'SMS') provided by mobile telephone carriers as a medium are gradually increasing.

【0003】

[Problems to be Solved by the Invention]

However, the simple SMS advertisements currently in force have some limitations in terms of advertising effectiveness. First, the short message transmitted through SMS is extremely short in length, so it is not possible to sufficiently convey the message that the advertiser is trying to convey. A more fundamental problem is that most mobile subscribers are not interested in Junk Messages, such as advertising short sentences, and receive these messages because mobile phones are devices whose primary purpose is personal communication. It is common to delete it immediately. Considering that the majority of SMS ads are Sales Promotion Advertising aimed at direct promotion, this phenomenon can also pose a fatal problem to advertisers.

【0004】

Various ideas have been proposed to enhance the effectiveness of SMS advertising. An example of this is Targeted Transmission described in Korean Patent Publication No. 2000-72755 (Title of the Invention: Method and System for Providing Advertisements on the Network) dated December 5, 2000. According to this, the advertiser or the advertising service provider selects an advertising partner who meets certain conditions, and sends the advertising phrase only to the selected person. However, even with this targeted transmission, most phone users are not interested in short ad messages and get consent from mobile phone subscribers to receive SMS ads, unless they are attractive. Since it sends advertisements without sending advertisements, it also causes dissatisfaction among mobile phone subscribers as well as spam mails.

【0005】

Korean Patent Publication No. 2000-30677 dated June 5, 2000 (Title of Invention: Targeted Advertising and Active Advertising Access Method Based on Internet and Wireless Mobile Phones) and Published Patent Publication No. 2001 dated January 15, 2001 -0002782 (Title of the invention: Advertising system using mobile communication device) describes a method and system in which an advertising information provider provides advertising information only to an applicant who has applied for receiving advertising information data. .. According to these public relations, the advertisement information provider provides each advertisement information recipient with a certain amount of compensation by receiving the advertisement information. However, since the unit price of SMS advertisements is not very high, it is difficult for the advertisement information provider to provide the advertisement information recipient (that is, the mobile phone subscriber) with expensive compensation for receiving the advertisement. Further, in this case as well, since the advertisement information recipient can immediately delete the short advertisement message when it is received in the same manner as the spam mail, it is difficult to expect a large advertising effect from the advertiser's point of view.

【0006】

In addition, since the advertising message provided through SMS Push is short and simple text, it is difficult to appeal to the terminal user sensuously. Therefore, in order to enhance the advertising effect, it is preferable to provide an image advertisement in the form of a still image or a moving image, but if the terminal is not connected to the wireless Internet, such an image advertisement is provided to the terminal. Is practically difficult. Therefore, it can be said that there is an urgent need for measures to improve advertising effectiveness from the standpoint of advertisers and advertising agencies.

【0007】

The present invention has been made in view of the above problems, and an object of the present invention is to provide an advertiser with a large advertising effect and to provide an advertising information recipient with substantial compensation by receiving an advertisement. It is to provide an advertising method in an improved wireless communication network.

【0008】

Furthermore, another object of the present invention is a video advertisement in a new and improved wireless communication network capable of providing a large advertising effect to an advertiser and providing a substantial compensation by receiving an advertisement to an advertisement information receiver. It is to provide a wireless communication terminal that embodies the above.

【0009】

[Means for solving problems]

In order to solve the above problems, according to the first aspect of the present invention, the advertising method is supervised by an advertising providing system that can be connected to the wireless communication terminal through the wireless communication network. The advertisement providing system pushes the advertisement video data to the wireless communication terminal of the user who has applied for use in advance without obtaining the consent of a separate user for each push session, and stores the advertisement video data in the wireless communication terminal. By doing so, the advertisement video corresponding to the advertisement video data is displayed on the terminal at a certain time, that is, when a predetermined event occurs. The event is one of "standby state entry", "wireless internet connection trial", "short message transmission", "telephone reception", "wireless internet connection termination", "terminal on" and "terminal off". Can be one.

【0010】

The wireless communication terminal has a display, a call processing circuit for transmitting and receiving signals, a non-volatile memory for storing advertisement video data, and when a predetermined event occurs, the advertisement video data is stored in the non-volatile memory. It is preferable to provide a display means for reading from the display and displaying an advertisement image corresponding to the advertisement image on the display for a predetermined time. The advertisement providing system first transmits a short message including a predetermined service identification code representing the advertisement video data transmission service and a resource identifier representing the location of the advertisement video data on the network to the terminal, and the terminal transmits the short message. The advertisement video data is requested through the network. When the request is received from the terminal, the advertisement providing system provides the advertisement video data to the terminal in response to the request, but also provides a predetermined program script, and the program script provides the advertisement video data. Is stored in a predetermined position on the non-volatile memory. As a result, when a predetermined event occurs, the display means of the terminal can read the advertisement video data from the non-volatile memory and display the corresponding advertisement video on the display for a predetermined time.

【0011】

Further, according to another viewpoint of the present invention for solving the above problems, when receiving a short message in a certain format, it automatically connects to an external advertising server to receive and store the advertisement video data for a certain period of time. Is provided with a wireless communication terminal that displays an advertisement video corresponding to the advertisement video data. The wireless communication terminal includes a display, a call processing circuit for signal transmission / reception, a non-volatile memory for data storage, and storage means and display means. The storage means stores the advertisement video data received from the predetermined server through the call processing circuit in the non-volatile memory, and the display means reads the advertisement video data from the non-volatile memory when a predetermined event occurs. The advertisement video to be displayed is displayed on the display for a predetermined time.

【0012】

Further, according to another aspect of the present invention, the advertisement video in the wireless communication terminal that automatically receives and stores the advertisement video data from the external advertisement server and displays the advertisement video corresponding to the advertisement video data at a certain time. A display method is provided.

【0013】

Such an advertisement image display method can be embodied in a wireless communication terminal provided with a display and a non-volatile memory for data storage. First, the advertisement video data is received from a predetermined server, and the advertisement video data is stored in the non-volatile memory. Then, when a predetermined event occurs later, the advertisement video data is read from the non-volatile memory and the corresponding advertisement video is displayed on the display for a predetermined time. The event can be "standby entry", "wireless internet connection", "short message transmission", "telephone reception", "wireless internet connection termination", "terminal on" or "terminal off".

【0014】

When receiving the advertisement video data from the server, first, a short message including the service identification symbol and the resource identifier is received. Then, when the service identification code corresponds to the advertisement video data transmission service, the resource identifier is used to approach the server and receive the advertisement video data from the server. However, in other embodiments, the advertising video data can also be received from the server by WapPush.

【0015】

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and attached drawings, components having substantially the same function and configuration are designated by the same reference numerals, so that duplicate description will be omitted.

【0016】

First, the advertisement providing system according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram schematically showing the configuration of the connection relationship between the advertisement providing system and the wireless communication terminal for embodying the advertising method according to the present embodiment, and FIG. 2 is a block diagram showing the configuration of the connection relationship between the present embodiment. It is a flowchart which shows roughly the process which embodied such an advertising method.

【0017】

As shown in FIG. 1, the advertisement providing system 10 wirelessly communicates via the short message service server (SMSS; Short Message Service Server, 32) and the short message service center (SMSC; 30) of the wireless telephone network. A short message can be sent to the terminal 50.

【0018】

Further, the wireless communication terminal 50 can be connected to the advertisement providing system 10 through, for example, a wireless Internet based on a wireless application protocol (WAP).

【0019】

As shown in FIG. 2, in order to advertise, the advertisement providing system 10 first sends a short message to the terminal 50 via SMSS32 and SMSC30 (stage 80). The short message contains a teleservice ID (TID) and a callback URL for connecting the ad serving system 10.

【0020】

The terminal 50, which will be described later, identifies the short message transmitted by the advertisement providing system 10 from other short messages, and in response to this, automatically connects to the advertisement providing system 10. The TID of the short message transmitted by 50 preferably has a value different from that of the general TID. For example, when the TID used for transmitting a general character message is "65490", the TID of the short advertisement message according to the present invention can be set to "65497". However, in another modified embodiment of the present embodiment, it is possible to distinguish the advertisement short text message of the present embodiment from the general short text message by other parameters included in the short text message instead of the TID. Of course.

【0021】

The terminal 50 that has received the short message identifies whether the corresponding message is a general short message or an advertisement short message according to the present embodiment based on the TID.

【0022】

When the received short text message is determined to be the advertisement short text message according to the present embodiment, the terminal 50 uses a callback URL via the wireless Internet based on a protocol (for example, WAP) supported by the wireless telephone network. Automatically connected to the ad serving system 10 (stage 82). For this reason, it is preferable that the terminal 50 is equipped with a program module that automatically tries to connect to the advertisement providing system 10 when a short message having a specific TID is received, and is executed. This will be described in detail.

【0023】

When the terminal 50 connects to the advertisement providing system 10, it does not require the consent of the terminal user or a specific action (for example, pressing a call button). In particular, normally, when a wireless communication terminal receives a short message, the user is notified of the arrival of the message by beeping, blinking the LED, and turning on the backlight of the display. The wireless communication terminal according to the present embodiment does not take such an operation in the process of receiving the short advertisement message and connecting to the advertisement providing system, and maintains a silent state.

【0024】

Therefore, the user does not know whether or not the short advertisement message has been received unless the call transmission test is performed. However, when receiving a normal short message, it goes without saying that the wireless communication terminal according to the present embodiment also notifies the user of the arrival of the message through the operation described above.

【0025】

On the other hand, it is preferable that the wireless telephone operator does not charge for the call connected to the advertisement providing system 10 in response to the short advertisement message in consultation with the advertisement providing system operator. In this case, the terminal 10 is provided with a special connection number different from the normal wireless Internet connection number (NAI) for the connection to the advertisement providing system 10, and the terminal 50 uses this number to provide the advertisement providing system 10. Try to connect to.

【0026】

When the terminal 50 connects to the advertisement providing system 10, the advertisement providing system 10 downloads one or more advertisement content data to the terminal 50 (stage 84). The advertisement content data is for displaying a still image or a moving image advertisement on the terminal display, and is in a format used for, for example, WBMP (Wireless Bitmap) or SIS (Simple Image Service, registered trademark). There is.

【0027】

After downloading the advertisement content data, the terminal 50 stores the advertisement content in the internal memory and ends the call processing (stage 86). If a call is received or made during the download of advertising content, the download will be suspended, and after a certain period of time, the connection and download will be performed again.

【0028】

With the advertisement content data stored in the memory, the terminal displays the advertisement video corresponding to the advertisement content data on the display each time a specific event occurs (stage 88).

【0029】

Examples of events in which the advertisement video is displayed in this way include entering the standby state (flip or opening a folder, etc.), wireless Internet connection trial, wireless Internet termination, short message transmission, telephone reception, terminal on / You can mention off and so on.

【0030】

For example, an advertisement image is displayed on the display from the moment the terminal enters the standby state, and this display state continues until the keypad is pressed or the standby state is terminated. As another example, the advertisement video is displayed on the display from the moment the user presses the wireless internet connection button and tries to connect to Nate (NATE, registered trademark), for example, but this display state is connected to the Nate server. Can last up to, or for a period of time.

【0031】

In the 84th stage, when the advertisement content data is downloaded, the control information regarding the advertisement display is also provided, and various controls are performed when the advertisement video is displayed by this information. For example, if a specific key (for example, "confirmation key" or "call key") of the terminal is pressed while the advertisement video is displayed, the advertisement is directly connected to the wireless Internet site related to the advertisement. Detailed information about is displayed on the display of the terminal.

【0032】

On the other hand, the advertising content data stored in the terminal is composed of one or more advertising content data. In particular, the above-mentioned advertisement content data can be separately prepared for each event.

【0033】

Furthermore, a large amount of advertisement content data is stored for a specific event, and each time an event occurs, a plurality of advertisement videos mapped to the event can be rotated and displayed. On the other hand, such advertisement content data is stored in the non-volatile memory of the terminal 50, and the stored state is maintained even when the power is turned off.

【0034】

In the present embodiment, the above-mentioned advertising method is performed only on the terminal of the user who has applied for receiving the advertisement. In particular, such an advertisement reception application is made at the time of purchase of the terminal. In this case, the terminal is equipped with a program module necessary for receiving and displaying the advertisement content data from the time of shipment, and operates the advertisement providing system. A person can provide various forms of compensation such as call charge reduction / exemption or assistance, terminal purchase cost support, and point accumulation for the amount corresponding to the advertisement reception period. Of course, the application for receiving advertisements and the withdrawal of the application can be made after the purchase of the terminal.

【0035】

The method of applying for and withdrawing advertisements can be the same as the method for other additional services implemented by the mobile telephone operator. If the reception application is withdrawn after the fact, the payment of the advertisement compensation system to the relevant user will be stopped. If the reception application is made after the fact, the counter-benefit to the relevant user can be call charge support or point accumulation.

【0036】

On the other hand, if a terminal user who does not have a program for embodying the advertisement providing system according to the present embodiment makes a reception application after the fact as described above, it is necessary to upgrade the terminal control program. is there.

【0037】

In addition, when the terminal user applies for cancellation of advertisement reception, the advertisement video display function of the terminal is deactivated, and when the terminal user applies for advertisement reception again, the advertisement video display function of the terminal is activated. It needs to be reactivated. The change of the advertisement display function activation / deactivation state on such a terminal can be set by using a short message, and the function activation / deactivation state is the non-volatile memory of the terminal. It is preferably stored in. A separate TID can be assigned to change the activation / deactivation status of the advertisement display function through a short message.

【0038】

By the way, another short message entity (Short Message Entity) registered in SMSS32 of the wireless telephone network, which is not the advertisement providing system 10 according to the present invention, transmits a short message using the same TID as the advertisement short message according to the present embodiment. If you do, it will cause serious problems for your system. Therefore, when SMSS32 is requested to send a short message using the same TID as the advertisement short message according to this embodiment, it confirms the IP address of the server that requested this and is a pre-authenticated advertisement providing system. Only the short sentences requested by 10 will be shipped.

【0039】

FIG. 3 specifically shows one embodiment of the advertisement providing system of FIG. 1 and its network environment. The advertisement providing system 10 according to the present embodiment is suitable for providing advertisement content data to a terminal based on WMLscript, and includes a main server 12, an advertisement phone server 14, and a download server 16. Is done.

【0040】

The operator of the advertisement providing system 10 provides various advertisements (for example, short message advertisement through short message service (SMS)) in addition to the push advertisement according to the present embodiment. The main server 12 controls the entire system 10 so that a plurality of advertising businesses can be managed collectively.

【0041】

The advertisement phone server 14 makes an advertisement according to the present embodiment. That is, the advertisement phone server 14 manages the user data for embodying the advertisement providing system according to the present embodiment, performs the process of selecting the advertisement target, and sends a short message to the user terminal 50 through SMSS32. Then, the download server 16 downloads the advertisement content data to the user terminal 50.

【0042】

The download server 16 stores a large amount of advertisement content data, identifies each terminal based on the terminal number, and provides WAP content to the corresponding terminal in response to the request of the terminal. In particular, according to the present embodiment, the WAP content provided by the download server 16 includes a WML script that enables the advertisement content data specifically specified for each terminal to be provided to the relevant terminal. ..

【0043】

In the wireless telephone network 20, a large number of base stations 24 for relaying call signals transmitted and received between the terminal 50 and the exchange 22 are connected to the wireless exchange 22. Here, the radiotelephone network 20 usually includes one central exchange and many wireless exchanges connected to the central exchange, but FIG. 3 briefly shows only one exchange. The WAP gateway 28 is connected to the wireless switch 22 through IWF (Interworking Function, 26).

【0044】

IWF26 is a gateway that connects wireless communication networks and wired communication networks. It is a device that is used daily by businesses in the wireless communication field. A detailed description will be omitted here.

【0045】

The WAP gateway 28 functions to convert the HTTP protocol stack into the WAP protocol stack, and conversely, convert the WAP protocol stack into the HTTP protocol stack.

【0046】

On the other hand, a short text service center (SMSC, 30) for providing a short text message service is connected to the wireless exchange 22, and at least one short text service server (SMSS, 32) is connected to the short text service center 30.

【0047】

The short text service center 30 is connected to the switchboard of the wireless telephone network by a common line (SS No. 7) signal system interface, and stores and transmits short text messages sent and received by each terminal user. 32 performs an interlocking function with an external network.

【0048】

The advertisement phone server 14 of the advertisement providing system 10 is connected to the short sentence service server 32 via the short sentence gateway server (SMS G / W, 34). Therefore, when the advertising phone server 14 tries to send a short sentence message to the terminal 50, the advertising phone server 14 requests the short sentence service server 32 to send the message via the SMS G / W 34.

【0049】

The download server 16 is connected to the WAP gateway 28 via a wireless interface gateway (WIG; 36), and downloads advertisement data when the terminal 50 is connected. It is also possible to connect the advertising phone server 14 to SMSS32 through WIG36.

【0050】

The advertisement providing system 10 according to the present embodiment is operated by another operator other than the telephone operator that operates the wireless telephone network 20. In this case, the download server 16 can be operated by the advertisement providing system 10 operator, but can also be operated by a telephone operator or a third operator. Of course, the entire advertising provision system 10 can also be operated by the telephone carrier.

【0051】

In addition, as shown in Fig. 3, the main server 12, the advertising phone server 14, and the download server 16 are individually shown focusing on their functions, but some or all of these servers are within one physical server. It can also be embodied.

【0052】

Next, the advertising method according to the present embodiment will be described with reference to FIG. FIG. 4 is an explanatory diagram showing concretely the advertising method supported by the system and network environment shown in FIG.

【0053】

First, as shown in FIG. 4, the main server 12 shown in FIG. 3 registers advertisement-related data such as the advertiser, the advertisement scale, and the advertisement target group in the advertisement phone server 14 (stage 100).

【0054】

Next, the advertising phone server 14 registers the advertising content on the download server 16 (stage 102). In the 104th stage, the advertising phone server 14 requests SMS G / W34 to send a short message to the terminal 50 belonging to the target group, and in response to this request, SMS G / W34 has TID for advertising. A short message set with TID is sent to terminal 50 via SMSS32 (stage 106). SMSS32 preferably distributes short messages in a distributed manner during the off-season of the IWF system in consideration of the load on each base station.

【0055】

On the other hand, when a reception confirmation (ACK) signal is received from the terminal 50 (stage 108), SMSS32 reports the shipping result to SMS G / W34 (stage 110).

【0056】

Next, the terminal 50 that receives the short message is automatically connected to the download server 16 by referring to the callback URL (stage 112). When the terminal 50 is connected, the download server 16 will provide WAP content, but the WMLscript included in the above WAP content will download the advertisement content data predetermined to the terminal 50. (Episode 116).

【0057】

When the download is completed, the download server 16 reports to the advertising phone server 14 that the download is completed (stage 118). On the other hand, SMSS32 can try to reship one or more short messages that failed to be transmitted accurately in the 106th stage.

【0058】

When the advertisement content data is downloaded, the WMLscript executed on the terminal 50 stores this data in the memory, so that the advertisement video can be displayed on the display every time a specific event occurs as described above. , This allows the advertisement to be exposed to the device user (stage 120). The specific content of advertising exposure will be described later.

【0059】

On the other hand, the main server 12 can inquire the advertisement result from the advertisement phone server 14 each time each advertisement is performed or periodically, and can receive the advertisement execution result and the analysis data (stage 122).

【0060】

Further, in the 116th stage, the existing advertisement analysis result data of the corresponding terminal is transmitted from the terminal to the advertisement phone server 14 immediately before or immediately after the download. The advertisement analysis result data can include the terminal number, advertisement ID, exposure screen information, cumulative number of advertisement exposures, advertisement exposure start time, advertisement exposure end time, etc., and this value is transmitted to the advertisement server. It is used to clearly analyze the results of advertising reactions.

【0061】

FIG. 5 is a block diagram showing the wireless communication terminals shown in FIGS. 1 and 3. In the terminal 50 of FIG. 5, the RF (RF) transmitter / receiver 202 receives a radio signal through the antenna 200, converts it into a baseband signal, and converts it into an analog / digital converter and a digital / analog converter (ADC / DAC, 204). Provided, the baseband signal output by the ADC / DAC 204 is converted into the RF band and output through the antenna 200.

【0062】

The ADC / DAC 204 converts the analog signal from the RF transmitter / receiver 202 into digital data and provides it to the digital processor 206, and converts the digital data from the digital processor 206 into an analog signal and provides it to the RF transmitter / receiver 202.

【0063】

The digital processor 206 includes a modem 208, a voice codec 210, and a control program 212. Modem 208 receives the downward modulation data from the ADC / DAC 204 and demodulates it by spectral backspread, and receives the upward data from the audio codec 210 and modulates it by spectral diffusion.

【0064】

The audio codec 210 decodes the demodulated data and outputs it to the speaker 220 via the amplifier 218, receives the audio signal input from the microphone 222 through the amplifier 224, encodes it, and outputs the encoded data to the modem 208. To provide.

【0065】

The control program 212 controls the operation of the entire terminal internal circuit including the modem 208 and the voice codec 210. The control program 212 can approach the RAM 214 and the flash memory 216.

【0066】

RAM214 temporarily stores data that is temporarily generated during the operation of the terminal. Flash memory 216 stores at least a portion of personal information such as address books and message storage boxes and control program code. In particular, according to the present embodiment, the flash memory 216 stores the advertisement data downloaded from the advertisement providing system 10 so that the control program 212 can display the advertisement video corresponding to the advertisement data through the LCD 228.

【0067】

On the other hand, the LCD 228 is connected to the digital processor 206 through the LCD driver 226, the keypad 230 is connected through the keypad interface 232, and the LED 234 is connected directly or through a separate interface.

【0068】

FIG. 6 is a block diagram schematically showing the structure of an embodiment of the terminal control program 212 shown in FIG. 5 with a focus on tasks. The control program 212 includes a user interface module 250, a call processing module 252, and a short message processing module 254. The user interface module 250 displays the current operating status of the terminal and other information on the LCD 228, and receives the user input information from the keypad 230.

【0069】

The call processing module 252 controls the operation of the modem 208 and the voice codec 210 so that the call can be made or received so that the communication can be smoothly performed while the call path is set. The short message processing module 254 sends a short message through the call processing module 252 according to the instruction of the user interface module 250, and processes the short message received through the call processing module 252.

【0070】

In particular, the short message processing module 254 according to the present embodiment includes a display / storage routine for processing a normal short message and an automatic connection routine for processing an advertisement short message according to the present invention.

【0071】

When the short message received through the call processing module 252 is a general message, the above display / storage routine causes the user interface module 250 to display the message contents on the LCD 228 and stores the message contents in the DB of the flash memory 216. ..

【0072】

On the other hand, when the received message is an advertisement short text message according to the present embodiment, the short text message processing module 254 calls without displaying the fact that the message has arrived at LCD228 or storing the message in the DB. Processing module 252 will be able to connect to download server 16 using the callback URL, but this function is performed by the automatic connection routine.

【0073】

The terminal control program 212 shown in FIGS. 5 and 6 according to this embodiment is mounted on the flash memory 216, and when the terminal is turned on, it is loaded into the digital processor 206 and executed. On the other hand, in addition to the terminal control program 212 shown in FIG. 6, WML scripts (SetADImage () and UploadStatus () functions) provided and executed from the download server 16 of the advertisement providing system 10 are also shown.

【0074】

The above SetADImage () function downloads the advertisement content data from the download server 16 and stores it in the specified location of the flash memory. The UploadStatus () function uploads the advertisement analysis result data stored in the flash memory of the terminal to the download server 16.

【0075】

Of these, the parameters of the SetADImage () function, which have a particularly important meaning, and their meanings or functions are summarized as follows.

【0076】

[table 1]

<img file="JP2003091679A_D0001.tif" />【0077】

After processing the advertisement image data, the SetADImage () function returns the return value to the download server 16, which allows the download server 16 to check whether the data processing has been completed successfully on the relevant terminal. .. As will be described later, a large number of advertising contents can be stored in the terminal, and a large number of content files can be transmitted from the download server 16 to the terminal in one download session.

【0078】

In this case, N advertisements can be transmitted by repeatedly using the SetADImage () function with different parameters or by defining similar functions with only the required numbers. In addition, the WAP content provided to the terminal by the download server 16 automatically connected by the callback URL includes advertisement control information, which will be described later.

【0079】

On the other hand, when the short-text message processing module 254 sends and receives a short-text message instructing the change of the advertisement display function activation / inactivation state on the terminal, the advertisement display flag of the flash memory 216 is displayed in Enable Mode or It is set to one of the display disable modes (Disable Mode).

【0080】

Only when the advertisement display flag of the flash memory 216 is set to the display enable mode, the user interface module 250 calls the advertisement content data stored in the flash memory 216 every time the above-mentioned event occurs. The corresponding advertising image is displayed on the LCD228.

【0081】

Hereinafter, the advertisement data download and advertisement exposure process in the wireless communication terminal 50 will be described in more detail with reference to FIGS. 7 to 10.

【0082】

Figure 7 shows the processing process when the wireless communication terminal 50 receives a short message. When the short message is received in the 300th step, the short message processing module 254 checks the TID and determines whether the short message is the advertising short message of the present invention (stage 302).

【0083】

If it is determined in the 302nd stage that the short message is not an advertisement short message, the short message processing module 254 processes the corresponding message by a general short message processing routine (stage 304). That is, the short message processing module 254 stores the received short message in the message inbox of the flash memory 216, and then notifies the user interface module 250 of the arrival of the message, whereby the user interface module 250 displays the letter bag icon. It is displayed on the LCD228, and a beep sounds through the speaker 220 while blinking the LED lamp 234 for a certain period of time.

【0084】

On the other hand, if the short message is judged to be an advertisement short message in the 302nd stage, the short message processing module 254 stores the message in the message inbox of the flash memory 216 and the message arrives at the user interface module 250. No notification (stage 306).

【0085】

Therefore, even though the short message is received, the arrival guidance through the letter bag icon, the LED lamp 234 and the speaker 220 is blocked. The short message processing module 254 provides the callback URL to the call processing module 252 so that the call processing module 252 attempts to connect to the download server 16 through WAP.

【0086】

When the terminal 50 is connected to the download server 16, WIG36 provides the corresponding terminal number together with the download server 16. The download server 16 confirms whether the relevant terminal user has applied for the advertisement reception according to the present invention based on the terminal number data, and downloads the advertisement content data for the relevant terminal (stage 308).

【0087】

The data provided by the download server 16 to the terminal through one or more consecutive sessions will form a series of data frames. Such a data frame structure is shown in FIG.

【0088】

As shown in FIG. 8, the data frame includes a frame header 350, control information 352, and a large number of advertising video data 354,356,358. The frame header 350 contains information on the file size (total_file_size), the number of advertisements (total_AD_count), the control information size (control_info_size), the time span start point (start_time_span), and the time span period (time_span_term) of the entire frame.

【0089】

Here, the time span means the cycle in which the advertisement exposure counter is reset and the count is restarted, and the time span start point means the time when the period of the first time span starts. On the other hand, the control information 352 represents a mapping rule for storing each advertisement video data in the flash memory 216.

【0090】

Each advertisement video data includes information for the relevant advertisement video (AD [n] _info, nth advertisement material information) and a video advertisement content file (AD [n] _data_compressed, nth advertisement).

【0091】

Each advertisement information (AD [n] _info) includes the size of the advertisement (AD_size), advertisement ID (AD_ID), exposure screen information (showing_position), daily target count (daily_target_count), and expiration date (expiration_date). ), And contains information such as the advertising URL (AD_URL).

【0092】

The advertisement URL (AD_URL) is a URL that allows you to directly connect to the wireless Internet site associated with the advertisement by pressing a specific key on the terminal when the advertisement is exposed.

【0093】

As shown in FIG. 7, the above-mentioned WML script stores the advertisement compressed file, that is, each advertisement information and advertisement content file in the mapped space in the flash memory (stage 310).

【0094】

FIG. 9A shows an example of allocating the advertisement video data storage space in the flash memory 216 of the wireless communication terminal. As shown in FIG. 9A, the flash memory 216 includes a user storage space 370 in which the user can arbitrarily store photographs and other images, and an advertisement-dedicated space 372 in which the advertisement image data is stored. Includes application program storage space 374 to be stored.

【0095】

In the advertisement-only space 372, it is preferable to prohibit data writing by the user. In the application program storage space 374, the advertisement reaction result information, that is, the statistical material for the exposure of the advertisement video to the user is stored together.

【0096】

On the other hand, in addition to the advertisement video data, the DB of the flash memory 216 is provided with the advertisement address information management table as shown in FIG. 9 (b). Assuming that the advertisement video data file is physically stored in the advertisement-only space 372 shown in FIG. 9 (a) as shown in FIG. 9 (c), the address information management table is used for each advertisement video. By storing the address where the file is stored, the user interface module 250 can easily call each advertisement video file when the advertisement is exposed.

【0097】

On the other hand, the flash memory 216 of the wireless communication terminal is further provided with the advertisement exposure screen management table shown in FIG. The management table stores the advertisement video file displayed for each event and the data for the exposure status of each video.

【0098】

In Fig. 10, the advertisement video is displayed when any one of the seven types of events occurs. For these types of events, "standby", "wireless internet connection", "SMS transmission", and "telephone" There are "Receive", "Wireless Internet end", "Terminal on", and "Terminal off".

【0099】

Of these events, for "standby", "wireless internet connection", and "SMS transmission event", there are three advertising video files (* -1, * -2, * -3) with different screen_IDs. It is mapped, and three advertisement images are displayed in rotation for each event type.

【0100】

For example, if the previous "standby" screen ID is "1-1" and the advertisement video with the advertisement ID (AD_ID) "AD_1" is exposed, the ID of the corresponding screen will be "" when the next wait event occurs. It becomes 1-2 "and the advertisement video with the advertisement ID (AD_ID) of" AD_2 "is exposed.

【0101】

Therefore, as shown in FIG. 10, the pointers p1 to p7 provided for each event type point to the screen ID displayed immediately before or the screen ID displayed next. In the case of "Call reception", "Wireless Internet termination", "Terminal on", and "Terminal off" events, only one advertisement video file is mapped for each event type, so the file validity period ends. Unless otherwise, one advertising video is fixedly exposed.

【0102】

As described above, three screen_IDs are assigned to three types of events out of the seven types of events according to the present embodiment, and a total of 13 screen IDs exist. The advertisement video file mapped to each of the 13 screen IDs can be partially or wholly superimposed. That is, some advertising video files can be displayed for two or more types of events. For example, an advertisement video having an advertisement ID of "AD_1" can be displayed not only when a "standby" event occurs but also when a "wireless Internet connection" or "call reception" event occurs. As shown in FIG. 10, it can be seen that the 6 advertising images are partially superimposed and mapped on the 13 screen IDs.

【0103】

The validity period of the advertisement video file is set for each screen ID, and the advertisement video file is displayed on the terminal only up to the validity period. If new advertisement video file data is not provided from the advertisement providing system 10 until the valid period, the advertisement video set as the basic video (default image) is displayed.

【0104】

In addition, the advertisement exposure target value to be displayed for each screen ID or event throughout the day, that is, the target count is set, and the daily exposure count indicating the number of times the terminal is exposed to the actual advertisement is displayed in the table. It is stored.

【0105】

The daily exposure count represents the number of times the advertisement is exposed on a daily basis, and if the number of daily exposures reaches the target count, the advertisement will not be displayed any more.

【0106】

However, in order to prevent abuse when the number of daily exposures reaches the target count, when opening and closing the terminal folder repeatedly (for example, repetitive operation within 2 seconds), this is an advertisement exposure. It will not be certified and will utilize the time span and time span cycle as described above.

【0107】

That is, it is preferable that the daily exposure count is restarted at a fixed time span cycle so that the user can watch the advertisement video at least a certain number of times when the event occurs.

【0108】

On the other hand, in the case of events that occur frequently or that the user sees the LCD for a very short time, for example, "Call reception", "Wireless Internet termination", "Terminal on", "Terminal off" events. It is not necessary to count the number of times the advertisement is exposed separately. It is also possible to ensure that the advertisement video is displayed when an event occurs for a certain period of time every day regardless of the daily exposure count.

【0109】

FIG. 11 shows the process of determining and displaying the exposure advertisement image in the wireless communication terminal. The event processing function Event_Handler () in the user interface module 250 of the terminal control program continuously checks the state change of the terminal (for example, key input, folder / flip opening / closing, power off, etc.). Such a state change is referred to as an interrupt event in the present specification, and the Event_Handler () function performs the process shown in FIG. 11 each time such an interrupt event occurs.

【0110】

First, as shown in FIG. 11, the above function determines whether or not the generated event is an event in which the advertisement should be displayed (stage 400). If the event that occurred is not the event for which the advertisement should be displayed, it returns to the waiting state waiting for the interrupt event again.

【0111】

However, if it is determined that the event that occurred in the 400th stage is an event that the advertisement should be displayed, the event in which multiple advertisement images are displayed in rotation (that is, "wait", "in the example of FIG. 10", " Determine if it is a "wireless internet connection" or "SMS transmission" event) (step 402).

【0112】

If it is determined that the generated event is not an event in which multiple advertisement videos are displayed in rotation, but an event in which only one advertisement video is mapped, the process proceeds to the 416th stage and the event is mapped to the corresponding event. Display the advertisement video on LCD228.

【0113】

If the generated event is judged to be an event in which multiple advertisement videos are displayed in rotation in the 402nd stage, the pointer to the event is used to determine the advertisement ID (AD_ID) to be displayed (No. 402). 404 steps).

【0114】

After that, it is determined whether the validity period of the advertisement ID determined in the 404th stage has passed (the 406th stage). If the validity period of the advertisement ID has expired, after displaying the basic video (for example, the default video that is installed from the time of shipment of the terminal or arbitrarily set by the user) (stage 408), It returns to the standby state waiting for the interrupt event again.

【0115】

On the other hand, if the validity period of the advertisement ID does not elapse, it is judged whether the daily exposure count value is smaller than the target count (stage 410). If the corresponding advertisement video is already exposed a lot on the day and the daily exposure count value is equal to the target count, after increasing the daily exposure count and the pointer in the 412th stage, the 404th to 410th stages are performed. Repeat.

【0116】

When the daily exposure count value is equal to the target count for all the advertisement videos, the state returns to the standby state waiting for the interrupt event. On the other hand, if the daily exposure count value is smaller than the target count in the 410th stage, the advertisement image is displayed after increasing the daily exposure count and the pointer (stages 414 and 416).

【0117】

The advertisement providing system 10 holds the advertisement data information currently stored in the terminals of all the users who have applied for the service. FIG. 12A is an explanatory diagram showing a final advertisement information table for each terminal held by the advertisement providing system 10. In the final advertisement information table, demographic information of the user and the type of advertisement video currently stored for each advertisement exposure screen are written for all terminals.

【0118】

As shown in Fig. 12 (a), the advertisement ID is simply displayed with one character (A to F) to improve understanding, and the question mark (?) Is the basic image (default) unique to the relevant terminal. image) is represented.

【0119】

As shown in FIG. 12 (b), the advertisement providing system 10 performs targeted transmission based on the advertisement information management table in consideration of the demographic data for each user and the reaction result to the advertisement.

【0120】

As shown in Fig. 12 (a), the following is an example of the advertisement shipping scenario until the final advertisement information table is generated. For example, if it is assumed that the advertisement video data will be shipped to men and women in their 30s before January 31, 2002, as shown in [Table 2] below, the data will be sent to the terminal, although it will be shipped over three times. Shipped to and stored in MIN1, MIN2, MIN4, MIN8, MIN11.

【0121】

[Table 2]

<img file="JP2003091679A_D0002.tif" />【0122】

Assuming that the advertisement video data as shown in [Table 3] below will be sent to men and women in their 20s before January 31, 2002 as the second time, such data will be the terminals MIN3, MIN5, MIN7, MIN10, Shipped to MIN12 and stored.

【0123】

[Table 3]

<img file="JP2003091679A_D0003.tif" />【0124】

As the third time, on February 2, 2002, it will be shipped only to the users in their 20s and 30s who have the expired B file set on the (2-1) and (2-2) screens. Assuming, the advertisement compressed file is shipped to and stored in the terminals MIN2, MIN5, MIN8, MIN12.

【0125】

It is not necessary to send the data to the other advertisement exposure screens whose validity period has not expired to the above users, and only the data to the screens whose validity period has expired need to be sent. Therefore, in this case, as shown in [Table 4], only the advertisement video data is included in the advertisement compressed file and shipped.

【0126】

[Table 4]

<img file="JP2003091679A_D0004.tif" />【0127】

On the terminal that received the above-mentioned advertisement compressed file, the video data for the corresponding advertisement exposure screen is changed from the existing'B'that has expired to'F'. On the other hand, on the terminals MIN1, MIN4, MIN11 where the above file has not been downloaded yet, the above-mentioned basic video is displayed on the screen (1-2, 2-2, F) where the'B'video was already displayed. ..

【0128】

In the embodiment described above in relation to FIGS. 3 to 9 (c), the WML script provided by the download server 16 of the advertisement providing system 10 stores the advertisement content data in the terminal.

【0129】

However, in other embodiments in which such an embodiment is modified, a virtual machine (V / M) mounted on the terminal can perform such a function instead of the WML script. FIG. 13 shows an advertisement providing system and its network environment according to such an embodiment.

【0130】

In the embodiment shown in FIG. 13, the advertisement providing system 450 includes a main server 452 and an advertisement phone server 454. The functions of the main server 452 and the advertising phone server 454 are almost the same as those in Fig. 3.

【0131】

However, as shown in FIG. 13, the content download server 460 that provides the advertisement video content is arranged outside the advertisement providing system 450. In this case, the download server 460 can be operated by a wireless telephone operator or a separate virtual machine solution operator. Of course, the download server 460 can also be operated directly by the advertisement providing system 450.

【0132】

When the terminal 50 that receives the short advertisement message is automatically connected to the advertisement providing system 450, the advertisement providing system 450 redirects the connection to the download server 460, and the download server 460 transfers the advertisement content to the terminal. To provide.

【0133】

The advertising content provided to the terminal 50 is preferably in a form in which one or more advertising video files are compressed and formatted into a fixed frame.

【0134】

The frame of the advertisement compressed file contains control information regarding the advertisement exposure, and the advertisement storage V / M of the terminal functioning as an advertisement dispatcher can perform various controls by using this information.

【0135】

After receiving the download of the advertisement compressed file, the terminal 50 decompresses the frame, decompresses the advertisement video data file, and restores the individual advertisement video data. After that, the terminal 50 stores the advertisement data in the internal memory and then ends the call processing.

【0136】

If a call is received or made during the download of the compressed advertisement file, the download is interrupted, and after a certain period of time, the connection and download are performed again.

【0137】

Similar to the first embodiment, the terminal displays the advertisement image corresponding to the advertisement data on the display each time a specific event occurs in the state where the advertisement data is stored in the memory. Then, when the user presses the specific key of the terminal while the advertisement video is displayed, the user can directly connect to the wireless Internet site related to the advertisement and see the detailed information about the advertisement.

【0138】

FIG. 14 is an explanatory diagram showing concretely the advertising method in the system and network environment shown in FIG. First, the main server 452 registers the advertisement-related data for the advertiser and the advertisement content of the relevant advertiser and the target group for which the relevant advertisement is to be executed in the advertisement phone server 454 (stage 470).

【0139】

The advertising phone server 454 registers the advertising content on the download server 460 and is assigned a service ID (SID) for the content (stage 472).

【0140】

In the 474th stage, the advertising phone server 454 requests the SMS G / W 34 to send a short message to the terminal 50 belonging to the target group, and in response to this request, the SMS G / W 34 sends the terminal 50 to the terminal 50. Send a short message (stage 476).

【0141】

Upon receiving the acknowledgment (ACK) signal from the terminal 50, SMSS32 reports the shipping result to SMSG / W34 (stages 478 and 480).

【0142】

Next, the automatically connected virtual machine (V / M) of the terminal 50 that received the short message is automatically connected to the download server 460 via the WAP gateway 28. That is, when the automatic connection V / M of the terminal 50 automatically connects to the advertisement phone server 454 by referring to the callback URL, the advertisement phone server 454 will redirect the connection to the download server 460 (Redirect). Stage 482, Stage 484).

【0143】

At this time, the advertisement phone server 454 generates and provides a VM script that specifies that the terminal receives the VM advertisement content for download from the download server 460.

【0144】

On the other hand, in FIG. 14, it is assumed that the callback URL is set as the URL of the advertising phone server 454, but in another embodiment obtained by modifying this embodiment, the callback URL is set as WAP gateway 28. Can also be done.

【0145】

Even if the above callback URL is set to WAP gateway 28, WAP gateway 28 will forward the connection to the download server 460. When the terminal 50 is connected, the V / M content download server 460 downloads the advertisement compressed file containing the predetermined content to the terminal 50 (stage 486).

【0146】

When the download is complete, the download server 460 reports to the advertising phone server 454 that the download is complete (stage 488).

【0147】

When the advertisement compressed file is downloaded, the advertisement storage V / M of the terminal 50 decompresses the file, stores each advertisement video content file and control information in the memory, and as described above, a specific event. The advertisement video is displayed on the display each time.

【0148】

As a result, the advertisement will be exposed to the terminal user (stage 490). The specific content for advertising exposure will be described later.

【0149】

On the other hand, the main server 452 can inquire the advertisement result from the advertisement phone server 454 each time each advertisement is performed or periodically, and receive a report on the advertisement execution result and the analysis result (stage 492).

【0150】

FIG. 15 is a block diagram schematically showing an example of a program mounted on a terminal suitable for the advertising method shown in FIG. The control program 212a includes a user interface module 250a, a call processing module 252a, a short message processing module 254a, an automatic connection V / M256 and an advertisement storage V / M258.

【0151】

The user interface module 250 displays the current operating status of the terminal and other information on the LCD 228, and receives user input information from the keypad 230.

【0152】

The call processing module 252a controls the operation of the modem 208 and the voice codec 210 to make and receive calls so that communication can be performed smoothly while the call path is set.

【0153】

The short message processing module 254a sends a short message through the call processing module 252a according to the instruction of the user interface module 250a, and processes the short message received through the call processing module 252a.

【0154】

In particular, in the present embodiment, when the short message received through the call processing module 252a is a normal message, the short message processing module 254a causes the user interface module 250a to display the message contents on the LCD 228 and the flash memory 216. Store in the DB of.

【0155】

On the other hand, when the received message is an advertisement short text message according to the present embodiment, the short text message processing module 254a does not display the message arrival fact on the LCD228 or store the message in the DB, and automatically connects V. Do / M256 to connect to the ad phone server 454 using the callback URL.

【0156】

In addition, when the short message processing module 254a sends and receives a short message instructing the change of the advertisement display function activation / inactivation state on the terminal, the advertisement display flag of the flash memory 216 is displayed in the display enable mode or the display disable mode. Set as one of them.

【0157】

Automatic connection The V / M 256 automatically connects to the V / M content download server 460 through the advertising phone server 454 according to the instructions of the short message processing module 254a.

【0158】

While connected to the download server 460, the advertisement storage V / M258 downloads the personalized and configured advertisement compressed file to the corresponding terminal, decompresses it, and stores it in the flash memory 216.

【0159】

In this embodiment, the automatic connection V / M256 and the advertisement storage V / M258 are stored in the application program space 374 shown in FIG. 9 (a), and are loaded into RAM at the same time when the terminal is turned on or thereafter. Will be executed.

【0160】

The above V / M may be installed in the memory inside the terminal from the time of shipment of the terminal, or may be installed in the memory by the user's program upgrade work after shipment. In addition, these two V / Ms can be separate scripts and can be integrated by one.

【0161】

When the advertisement display flag of the flash memory 216 is set to the display enable mode, the user interface module 250 calls the advertisement content data stored in the flash memory 216 each time the above-mentioned event occurs and corresponds to the above-mentioned event. Display the advertisement video on LCD228.

【0162】

Other features of the systems and methods shown in FIGS. 13 and 14 are similar to those in FIG. 3 or 4, and detailed description thereof will be omitted.

【0163】

In the above embodiment, the advertisement providing system provides the URL to the terminal by SMS push so that the terminal connects to the system, and then provides the advertisement video data, but the WAP push is not limited to such an example. It is also possible to provide the advertisement video data to the terminal.

【0164】

FIG. 16 shows the connection relationship between the advertisement providing system and the wireless communication terminal in this embodiment. FIG. 16 is substantially the same as FIGS. 3 and 13 except that a push proxy gateway (PPG) has been added and the configuration of the advertisement serving system is shown more simply.

【0165】

In the advertisement providing system 510, the main server 512 performs a function of managing a plurality of advertising businesses carried out by the advertisement providing system operator and managing the entire system 510.

【0166】

The advertising phone server 514 advertises the embodiment. That is, the advertisement phone server 514 manages user-specific data for embodying the advertisement providing system according to the present embodiment, and performs a process of selecting an advertisement target.

【0167】

In addition, the advertising phone server 514 provides information and advertising materials for the target terminal selected as the push proxy gateway (PPG; Push Proxy Gateway, 520), and requests that the advertising material be pushed to the target terminal.

【0168】

The push proxy gateway (PPG, 520) receives push content from the advertising phone server 514 by PAP (Push Access Protocol), converts it into a form suitable for wireless networks, and uses the push OTA (Over The Air) protocol to terminal. To transmit to.

【0169】

For this purpose, the PPG 520 is connected to the advertising phone server 514 and is connected to the IWF 26 via the WAP gateway 28. On the other hand, the WAP gateway 28 provides the PPG520 with information about the terminal for which the WAP session is currently formed so that the PPG520 can refer to the push content when pushing it to the terminal.

【0170】

For details on WAP Push and PPG520, see "WAP Push Architectural Overview (WAP-250-PushArchOveriew-20010703-a)" and "Push Message (Push Message)" among the materials published by WAP Forum (Wireless Application Protocol Forum Ltd.). WAP-251-PushMessage-20010322-a) , PushProxy Gateway Service (WAP -249-PPGService-20010713-a) , etc. are described in detail.

【0171】

FIG. 17 is an explanatory diagram schematically showing the structure of a program mounted on the terminal of FIG. 16 and executed, focusing on tasks. The call processing module 560 controls the operation of the modem and the voice codec so that the call can be made or received so that the communication can be performed smoothly while the call path is set.

【0172】

The user interface module 562 displays the current operating status of the terminal and other information on the LCD, and receives user input information from the keypad. The short message processing module 564 sends a short message through the call processing module 560 according to the instruction of the user interface module 562, and processes the short message received through the call processing module 560.

【0173】

In particular, in the present embodiment, when the short message received through the call processing module 560 is a normal message, the short message processing module 564 causes the user interface module 562 to display the message contents on the LCD. , Stored in the DB of the flash memory, but in the case of SIR (Session Initiation Request, which will be described later) according to this embodiment in which the message was sent by PPG520, the message arrival fact is displayed on the LCD and sent to the DB. Instead of storing the message, the WAP connection management module 566 connects to the wireless Internet and forms a push session with the PPG520.

【0174】

When the content is pushed from the PPG520, the application program dispatcher (Dispatcher, 568) determines the application program that uses the relevant content by looking at the header of the push message, and provides this to the relevant application program.

【0175】

In particular, according to the present embodiment, the application program dispatcher 568 provides the advertisement storage virtual machine (V / M) 570 when the advertisement compressed file is pushed from the PPG 520. In this case as well, the advertisement storage V / M570 performs a function similar to the SetADImage () function of the WML script described above, receives the advertisement compressed file from the application program dispatcher 568, decompresses it, and stores the advertisement video in memory. Store in.

【0176】

The stored video data is called and displayed by the user interface module 562 each time a specific event occurs.

【0177】

FIG. 18 is a flowchart showing an advertising method embodied in the network of FIG.

【0178】

As shown in FIG. 18, the advertising phone server 514 first transmits a push request message including the target terminal number and the advertisement compressed file to the PPG 520 (stage 580).

【0179】

Upon receiving the push request message, PPG520 checks whether a valid WAP session has been set for the corresponding terminal 550 (stage 582).

【0180】

As described above, the PPG 520 is provided with information from the WAP gateway 28 to the terminals for which the WAP session is currently formed periodically or in real time to determine whether or not the WAP session has been set for each terminal. be able to.

【0181】

Not limited to such an embodiment, it is also possible for the PPG 520 to inquire at the WAP gateway 28 whether or not a WAP session for a specific terminal has been set only when necessary.

【0182】

If it is determined that a valid WAP session exists in the terminal in the 584th stage, the process proceeds to the 592nd stage. On the other hand, if it is determined that there is no valid WAP session in the terminal 550 in the 584th stage, the push session setting process from the 586th stage to the 590th stage is performed.

【0183】

First, in the 586th stage of the push session setting process, the PPG 520 transmits a session setting request (SIR) to the terminal 550 through a short message.

【0184】

In order for the terminal 550 to identify the SIR short message sent by the PPG 520 from other short messages and respond to it, the TID of the SIR short message sent by the PPG 520 has a value different from that of the general TID. Is preferable. For example, if the TID used when transmitting a general character message is "65490", the TID of the SIR short text message is set to "65495". However, the present invention is not limited to this, and it is needless to say that the short message according to the present embodiment can be distinguished from the general short message by other parameters included in the short message instead of the TID.

【0185】

When the received short text message is determined to be a SIR short text message, the short text message processing module 564 of the terminal 550 activates the WAP connection management module 566 (stage 588).

【0186】

The WAP connection management module 566 is an SIA (Session Initiation Application) that sets the push session with the PPG, and the push session between the PPG 520 and the terminal 550 is set through the execution of the WAP connection management module 566 (stage 590). ).

【0187】

If it is determined that a valid WAP session exists in the terminal in the 584th stage, or a push session is set in the 590th stage, the PPG520 transmits the compressed advertisement file to the terminal through the push session in the 592th stage. ..

【0188】

Each time the content is pushed, the application program dispatcher 568 of the terminal determines the application program that uses the corresponding content based on the header of the push message, and provides this to the corresponding application program.

【0189】

In particular, the application program dispatcher 568 provides the advertisement image storage V / M 570 when the content pushed from the PPG 520 is an advertisement compressed file according to the present embodiment.

【0190】

The advertisement image storage V / M570 receives the advertisement compressed file, decompresses it, and stores it in the memory (stage 594). When the reception of the compressed advertisement file is completed, the push session between the terminal 550 and the PPG 520 is canceled, and the call channel is also terminated at this time.

【0191】

The stored video data is called and displayed by the user interface module 562 each time a specific event occurs.

【0192】

On the other hand, the WAP push service defined by the WAP Forum up to now is WML (Wireless Markup Language), MMF (Mobile Multimedia File Format), CO (Cache Operation), SI (Service Indication), SL (Service) depending on the media type to be pushed. Loading) and so on.

【0193】

In the case of WML (Wireless Markup Language), MMF (Mobile Multimedia File Format), and CO (Cache Operation) services, content can be provided to terminals by one-time push, but SI (Service Indication) And in the case of SL (Service Loading) service, only the URL of the CP is pushed, and the terminal connects to the CP using the above URL.

【0194】

Any of these services may be used when embodying the advertising content push according to the present embodiment. However, when pushing through the MMF service or CO service, the PPG520 finishes the push work when it is judged that a session exists in the 584th stage shown in Fig. 18, that is, when the terminal is connected to the wireless Internet. However, you can try again after that. In the case of CO service, it is suitable for updating the validity period of the data file already stored in the terminal.

【0195】

On the other hand, when pushing advertisement content using SI (Service Indication) and SL (Service Loading) services, the application program dispatcher 568 or WAP connection management module 566 automatically advertises without obtaining the consent of the terminal user. It is preferable to connect to the providing system 510.

【0196】

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to such examples. It is clear that a person skilled in the art can envision various modifications or modifications within the scope of the technical ideas described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs. For example, when providing advertising video content to a terminal based on SMS push as described above, it is preferable that the terminal executes tasks such as automatic connection to a server, content reception, storage, and reporting.

【0197】

In the above embodiment, some cases for embodying the task have been described as examples, but the present invention is not limited to such examples, and the use of built-in programs and V / M and WMLscript, etc. The use of scripting programs can be combined in a variety of ways.

【0198】

Further, in the above embodiment, a separate program module or function may exist for each of the above tasks, but some of them may be integrated or, conversely, may be further divided.

【0199】

Further, in the above embodiment, the case where the content provided from the server to the terminal is compressed and transmitted has been described as an example, but the present invention is not limited to such an example, and the case where the entire frame is compressed or When a part is compressed, the compressed portion and a more specific compression method can be variously modified and implemented.

【0200】

Further, in the above embodiment, the case where the callback URL is transmitted together with the transmission of the short message has been described as an example, but the present invention is not limited to such an example and is basically instead of providing the above callback URL. It is also possible to store a typical (default) URL in the terminal and connect using this URL.

【0201】

[Effect of the invention]

As described above, according to the present invention, from the advertiser's point of view, it is possible to provide a personalized advertisement based on the attributes of the target, that is, the owner of each mobile terminal. In addition, when considering the feature that the mobile terminal is carried 24 hours a day, the advertiser can maximize the advertising effect through the constant repeated exposure of the advertisement. By increasing the advertising effectiveness, the system operator can charge a higher advertising fee from the advertiser, and can give a substantial incentive to the service user.

【0202】

On the other hand, the service user feels almost no inconvenience because the advertisement data is downloaded only when the terminal is not used for voice communication or data communication, and in particular, the service is additionally used after purchasing the terminal. Since you can apply for cancellation and use, you can use it more conveniently.
