Detailed description of the preferred embodiments
Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
Fig. 1 is a block diagram illustrating the structure of a CDMA-type mobile radio communication network according to the present invention. With reference to Fig. 1, a caller information provision system of a mobile radio communication network according to the present invention includes a plurality of mobile terminals 10a to 10n, each of which incorporates a display device for displaying image information ; a base station and a base station controller 20 that processes the originating call signals and the destination call signals for the mobile terminals 10a to 10n, and provides radio channels to enable the transmission of radio information. image to the respective mobile terminals; a mobile switching center 30 that processes the originating call signals from the base station and the base station controller 20 and transmits the image information of a mobile terminal user to a destination mobile terminal to via a serving base station in the course of signal processing
ES 2 335 263 T3 of originating call; and an image service controller 40 transmitting to the mobile switching center 30 the image information corresponding to the home mobile terminal under the control of the mobile switching center 30.
An initial position register 60 is also connected to the mobile switching center 30 and manages the positions of the mobile terminals 10a to 10n; and a public switching network 70 is a general cable telephone network.
Each respective mobile terminal 10a to 10n is provided with a display device for displaying image information and / or character information, and a loudspeaker for outputting sound information. In particular, the image service controller 40 is provided with a separate memory for separately storing image information, character information, and sound information. Accordingly, when a home mobile terminal transmits a home phone call, one or a combination of the picture information, the sound information, and the character information may selectively be provided in the form of caller information.
In today's CDMA cellular mobile radio network, 64 channels are allocated for each frequency. The 64 channels include a pilot channel, a synchronous channel, and 7 paging channels while the remaining channels are traffic channels. Here, the paging channel transfers the message information from the base station to the mobile terminals. Important messages include system information, paging, command, and channel assignment.
For explanatory purposes, the following functions of the mobile radio communication network according to the present invention will be defined.
In the mobile radio communication network, a serving base station can selectively transmit a paging signal as well as picture information, character information, or sound information using either one or two paging channels. If two paging channels are used, a primary paging channel transmits the paging signal and / or audible information, and a predetermined secondary paging channel, transmits the character information and / or image information. At this time, if the image information is transmitted through the secondary search channel, the image signal transmitted through the main image channel includes a message informing that the image information is transmitted through the search channel. Secondary paging.
The image information can also be transmitted with traffic data to the destination mobile terminal through a traffic channel arranged within the mobile radio communication network. At this time, the image information is preferably located in front of the traffic data.
Also, the present invention uses an image compression technique to store and transmit a caller's image. Specifically, the size of the image can be fixed, for example in 64 x 64 bits, so that l resolution of the image information would be kept at a predetermined level and in such a way that the image information would have a minimum amount of data in the course of its storage and transmission. Alternatively, the original image information with a size of approximately 200 x 200 bits can be prepared, compressed, and transmitted while a destination mobile terminal can receive the compressed image information and convert the image size in accordance with the size of your own rendering device.
As shown in Fig. 2, each mobile terminal 10a to 10n according to the present invention includes a caller identifier detection unit 2, which receives a data frame transmitted through a paging channel, detects the caller's identifier, and receives the transmitted data if the identifier of the destination mobile terminal included in the data frame indicates itself to indicate output the received data according to the type of data; a signal processing unit 3, which respectively restores an output signal from the caller identifier detection unit 2 into an original sound signal, a character signal, or a picture signal; a processor 7, which respectively controls the storage and output of the sound signal, the image signal, or the character signal from the signal processing unit 3; an image size conversion unit 10 which converts the image signal or the character signal from the processor 7 into a predetermined size; a keyboard 8, which controls the processor 7; a memory 9, which stores the information output from the processor 7, an image display unit 11, which represents an image information output from the image size conversion unit 10; an LCD display unit 12, which represents character information output from processor 7; and a loudspeaker 7 which reproduces the sound information emitted from the processor 7.
In the exposed mobile terminal, the signal processing unit 3 includes a sound information processing unit 4, a character information processing unit 5, an image information processing unit 6 for, respectively, restoring the signal from the caller identifier detection unit 2.
ES 2 335 263 T3
Likewise, the service controller 40 in the image, as shown in Fig. 3, includes a data transmission / reception unit 41, which carries out data communication with the communication service provider operating center 50 or with the switching center 30; a caller identifier detection unit 42, which detects an identifier of a home mobile terminal from an output signal of the data transmission / reception unit 41; a control unit 44, which controls the storage of the caller identifier information provided from the data transmission / reception unit 41 or selectively outputs stored caller identifier information; a caller identifier information generation unit 43, which receives the caller identifier information output selectively from the control unit 44 and provides the caller identifier information to the data transmission / reception unit under control of control unit 44; and an identifier management unit 45, which manages the identifier of the respective mobile terminal in the form of a database under the control of the control unit 44.
Image service controller 40 also includes image memory 46 which stores image information or outputs image information stored under control of control unit 44; a character memory 47, which stores the character information or outputs character information stored under the control of the control unit 44; and a sound memory 48, which stores the sound information or outputs sound information stored under the control of a control unit 44.
The image service controller 40 examines its own identifier management unit 45 in accordance with a request from a mobile switching center 30, and whether the current home mobile terminal is a subscriber to whom an identification service is to be supplied of the calling party, the image service controller 40 provides the mobile communication center with pre-requested information between each mobile terminal and the communication service provider operating center 50 through the communication service provider operating center 50.
Specifically, the pre-requested information can be image information for the representation of the face of a user of the mobile terminal of origin, or character information for the representation of information, such as the telephone number, name and / or address. company name of the mobile terminal of origin. Likewise, the image service controller 40 can simultaneously provide character information with image information or can simultaneously provide image information, character information, sound information, which play the sound of character information.
Fig. 4 is a sequential flow diagram illustrating the process of recording image information in the CDMA mobile radio communication network in accordance with the present invention. First, the image compression method used in the present invention will be discussed.
In general, a JPG or JPEG 2000 protocol has been proposed as a standard method for understanding a still image. JPEG transforms a still image into a two-dimensional image using a discrete cosineideal transform (DCT), and then quantifies the transformed image to improve comprehension efficiency. However, this transformation has a drawback in that transformation processes must be carried out in both the forward and reverse directions. Therefore, there is a high probability that the JPEG-2000 protocol is the one adopted as the standard procedure using a wavelet technique, but JPEG-2000 represents a larger amount of computation compared to JPEG. In particular, the compression ratio of JPEG is approximately 20 - 80: 1 while the compression ratio of JPEG 2000 is 100: 1.
As compression techniques that can minimize the amount of computation in a state in which the user of a mobile terminal can recognize an image, delta modulation (DN) with a compression ratio can be taken into consideration, approximately, 4 to 1, differential pulse coding modulation (DPCM) with a compression ratio, approximately 6 to 1, an adaptive pulse coding modulation (ADPCM) with an approximate compression ratio of 8 to 1. In the case that these compression techniques are used, a robust process that is strong the correction of errors due to noise.
Referring again to Fig. 4, a mobile terminal user prepares image information, such as a photograph, or an image representing the character of the user using an input device, such as a scanner; and transmits the image information to the mobile switching center 30 through the base station 20 (steps a1 and b1). The mobile switching center 30 receives the image information data, and transmits the received image information data to the communication service provider operating center 50 for registration (step c1). The communication service provider operating center 50 then compresses the received image information in accordance with the determined standard or converts the size of the image information and transmits the image information to the image service controller 40 to request a registration. of the image information for an identification of the calling party (step d1).
According to the present invention, the image information can be transmitted after compression of the original 64 x 64 bit image, or after compression of the original 200 x 200 bit image. If the image
ES 2 335 263 T3 original is transmitted after compression of the 200 x 200 bit image, the target mobile terminal converts the size of the image according to the size of its own screen to represent the converted image on the screen. A detailed explanation of these will be offered later.
Upon receipt of a request for the registration of information of an image, the image service controller 40 registers information of the information in the memory 46 of the image and manages the image of the corresponding mobile terminal user in accordance with the request of the center operational 50 communication service provider. Next, the image service controller 40 transmits to the mobile switching center 30 a message informing the completion of the image storage, and then the mobile switching center transmits the same message to the home mobile terminal via base station 20 (steps e1 to g1).
In Fig. 4, a mobile terminal user can prepare character information, such as a name, business name, or a message representing the user's character using a computer or mobile terminal. In this case, the character information would be transmitted to the mobile switching center 30 through the base station 20 (steps a1 and b1). The mobile switching center 30 would receive the character information data, and transmit the received character data to the operational center 50 of the communication service provider (step c1). The operational center 50 of the communication service provider would request from the image service controller 40 a record of the character information for the identification of the calling party (step d1).
This image service controller 40 would record the character information in the character memory 47 and manage the character information of the user of the mobile terminal in accordance with the request of the operation center 50 of the communication service provider. Next, the image services controller 40 would transmit a message informing the completion of the character information storage to the mobile switching center 30, and the mobile switching center 30 would transmit the same message to the home mobile terminal via base station 20 (step e1 to g1).
Likewise, the user of the mobile terminal can prepare sound information, such as a song or accompaniment that represents the character of the user using a computer. In this way, the sound information would be transmitted to the mobile switching center 30 through the base station 20 (steps a1 to b1). The mobile switching center 30 would receive the sound information data, and transmit the received sound information data to the operating center 50 of the communication service provider (step c1). The operational center 50 of the communication service provider would request the image service controller 40 to register the audio information for the identification of the caller (d1).
The image services controller 40 would then record the sound information in the sound memory 47 and manage the sound information of the user of the mobile terminal in accordance with the request of the operation center 50 of the communication service provider. Next, the image services controller 40 would transmit a message informing the completion of the storage of the audio information to the mobile switching center 30, and the mobile switching center 30 would transmit the same message to the home mobile terminal through the mobile station 20 (steps e1 to g1).
In the registration process referred to above with reference to Fig. 4, the operational center 50 of the communication service provider or the terminal underwriting agency (not illustrated) can prepare the images of the respective users of the mobile terminals using a Image recognition device, such as a scanner or digital camera. The prepared image information is converted to a predetermined standard size, compressed, and then transmitted to the image service controller 40 for recording. Character information or sound information representing the character of the respective mobile users can also be prepared by the operational center 50 of the communication service provider or by the subscription agency of the terminal and be registered in the same way as the one described above.
Accordingly, if the mobile switching center 30 requests the caller's information, the image service controller 40 determines whether there is an image information, a character information and a sound information corresponding to the originating mobile terminal, using the registered information for the identification of the caller. The switching center 30 then selectively combines and transmits the determined calling party information between the home mobile terminal and the communication service provider operating center 50.
In the present invention, the image information may include a photograph of a home mobile terminal user registered in the image service controller 40, an image or character representing the user's characteristic, or a still image or an image. in motion taken by the user. The information of the mobile terminal of origin, the name, the business name, the message prepared by the user of the mobile terminal of origin and registered in the image services controller 40. The sound information can include a known song or accompaniment, a melody or an audible message prepared by the user of the home mobile terminal, and registered in the image service controller 40.
Image information, character information, and sound information can be prepared by a user using an input device, and registering the information in the image service controller.
ES 2 335 263 T3
40. The input device can be a wired / wireless remote control, keyboard, mouse, or pen mouse wired or wirelessly connected to the computer.
Also, a user of the home mobile terminal can select, register in the image service controller 40, and transmit image information provided by the operating center 50 of the communication service provider. Similarly, the user of the home mobile terminal can select, register with the image service controller 40, and transmit character information and / or sound information supplied from the operation center 50 of the communication service provider.
Said image information, as described above, can be transmitted by itself or in combination with one or both of the character information and the sound information. Also, the character information can be transmitted by itself or in combination with one or both of the image information and the sound information. Finally, the sound information can be transmitted by itself or in combination with one or both of the image information and the character information.
Image information, character information, and sound information, as described above, can be modified and / or expanded within the conditions supported by the communication system. Likewise, the image information, the character information, and the sound information can be classified according to each user registered in the operational center 50 of the communication service provider or according to each identifier of each mobile terminal of origin. and stored in the image service controller 40.
Accordingly, in the present invention, if the identifier of a source mobile terminal is different from the identifier of a destination mobile terminal, that is, if the source mobile terminal is different from the destination terminal, information is provided from the calling party to the destination mobile terminal where the calling party information may be one or a combination of the image information information, character information and sound information. If the identifier of the originating mobile terminal is the same as the destination mobile terminal, that is, if a user sends a page to his / her own mobile terminal, user information is provided to the user's own mobile terminal. the user where the user information can be one or a combination of the image information, the character information, and the sound information. In the latter case, the user can receive information intended only for his / her own user.
Here, the user can transmit caller information to a destination mobile terminal, including his / her own mobile terminal, using either the user's mobile terminal or using a computer or a network. The present invention will be discussed in connection with an embodiment in which a caller information is transmitted through a mobile terminal. With reference to Fig. 5, Suppose that in a process of transmitting the caller information through a mobile terminal, all types of data including the paging signal, the sound signal, the character signal, and the image signal can be transmitted.
As shown in Fig. 5, a home mobile terminal 10a requests a call connection to a base station 20a (step a2). The base station 20a receives the call request signal from the home mobile terminal 10a and transmits the call request signal to a mobile switching center 30a. Accordingly, the mobile switching center 30a obtains the location of the destination mobile terminal 10b through the location register and requests a search for the caller identification information from the home mobile terminal 10a to the service controller. image 40 (step b2).
The image services controller 40 performs a search for the caller identification information and determines whether there is an image information, a character information, or a sound information, corresponding to the home mobile terminal 10a. The image services controller 40 also determines which information is to be combined and transmitted, thereby selectively combining and transmitting the selected information as calling party information to the mobile switching center 30a (step c2). The switching center 30 transmits the information of the calling subscriber and the paging signal to a mobile switching center which controls a destination mobile terminal 10b (step d2), so that the identification information of the calling subscriber and the Paging signals are transmitted to the destination mobile terminal 10b (steps e2 and f2).
At this time, a base station 20b can transmit data such as paging signal, audio information, character information, and image information through a paging channel or traffic channel. Also, in the preferred embodiment, the base station 20b transmits the paging signal and the audible information to the destination mobile terminal 10b with a data frame structure as shown in Fig. 6 via the main paging channel. In such a case, the base station 20b would assign the predetermined secondary paging channel as a dedicated channel for the caller identification service, and transmit the character information and image information with a data frame structure such as shown in Fig. 7 through the dedicated channel.
When the image information or character information is transmitted along with the sound information using two channels, the base station 20b reports whether the image information or the character information
ES 2 335 263 T3 characters exist in field 5e of the secondary channel information of the message transmitted through the primary paging channel. Two paging channels can increase the efficiency of data transmission and reduce the load on the main paging channel since character information and audio information have different transmission rates.
Although the destination mobile terminal 10b of Fig. 5 is illustrated belonging to a control area of a mobile switching center 30b different from the mobile switching center 30a, the destination mobile terminal 10b may also belong to the mobile switching center 30a.
In the present invention, a destination mobile terminal 10b continuously monitors during an allocated time slot in each paging period whether a destination signal for the destination mobile terminal 10b is being transmitted. Here, the time slot allocated to the destination mobile terminal 10b in the paging channel may be 80 msec for a paging period of 5.12 sec. If an input frame contains an identifier of the destination mobile terminal, the caller identifier detection unit 2 of Fig. 2 detects corresponding data from the input frame.
From the detected data, the caller identifier detection unit 2 identifies the identifiers of the destination and origin mobile terminal 5a and 5b shown in Fig. 6, and determines the type of data transmitted through field 5c of the data type. The transmitted data may be a paging signal, for example a ring signal, a sound data, or both a paging signal and a sound data. Also, the secondary channel information field 5e includes a message informing about whether image information or character information has been transmitted through a predetermined secondary channel. Accordingly, if the caller identifier detection unit 2 determines that an image information and / or a character information has been transmitted, the destination mobile terminal 10b receives the image information or the character information by scrolling to the secondary page channel, and then back to the primary page channel.
The caller identifier detection unit 2 then determines whether the transmitted data is sound information, character information, or picture information. If the data is of a sound information, the sound information is transmitted to the sound information processing unit 4 for processing and is then transferred to the processor 7. If the data is an image information and / or a character information, the caller identifier detection unit 2 respectively transfers the image information and / or the character information to the processing unit 6 of the call information. image and character information processing unit 5. The character information processing unit 5 and the image information processing unit 6 restore the character information and the image information to the original 200 x 200 bit character signal and image signal, and transfer the information restored to processor 7 (see steps S1 and S2 of Fig. 8).
Processor 7 appropriately controls one or a combination of display unit 11, LCD display unit 12, and loudspeaker 13 depending on information from the calling party. For example, if the caller identification information corresponding to the home mobile terminal 10a represents that there is an image information, a character information, and a sound information, the processor 7 controls the image display unit 11 to represent the image information, controls the LCD display unit 12 to display the character information and controls the speaker 13 to reproduce the content of the character information.
The image information displayed in the image processing unit 11 can be processed in two ways. First, if the transmitted image information is determined to have a specific size (for example, 64 x 64 bits) in the system, the processor 7 represents the image information as it is from the processing unit 6 of the image information. Second, if the transmitted image information is a compressed image of 200 x 200 bit originals, the processor 7 converts the resolution of the transmitted image signal through the image size conversion unit 10 so that the size of the image information from the image information processing unit 6 corresponds to the size of the image display unit 11 of the mobile terminal.
Fig. 8 shows the second conversion process in which a compressed image is received (step S1) and restored to the original 200 x 200 bit image (step S2). The restored original 200 x 200 bit image is then transferred to a 256 x 256 bit image using horizontal interpolation or vertical interpolation (step S3). The processor 7 then either reduces the resolution of the transformed image information from 256 x 256 bits to 64 x 64 bits or 128 x 128 bits, or increases the transformed image information in size. Although any method can be used to reduce or enlarge the resolution, the processor reduces the resolution using a pixel hopping or averaging technique and increases the resolution size using a bilinear interpolation or a pixel doubling technique. Specifically, the resolution of the image is converted in accordance with the size of the image display unit 11 of the destination mobile terminal 10b (step S4).
The image information as converted in accordance with the above is stored in the memory 9 and displayed on the LCD display unit 12 under the control of the processor 7. According to the present invention
ES 2 335 263 T3 tion, by the representation of the image stored in the memory 9, a continuous representation of the image information can be maintained until a corresponding telephone call is completed.
Likewise, the processor 7 can provide sound information through the loudspeaker 13 after a destination call signal, or directly output the sound information, omitting the destination call signal.
Referring back to Fig. 5, if a user located at the destination mobile terminal 10b answers the telephone call after viewing the caller identification information, a response signal from the paging device is transmitted from the destination mobile terminal 10b to the centers corresponding mobile switching devices 30a and 30b, and a traffic path is determined between the source mobile terminal and the destination mobile terminal 10b (steps g2 to k2). Accordingly, the destination mobile terminal 10b may be provided with one or a combination of the image information, the character information, and the sound information as a requested calling party identification information service. through the operational center 50 of the communication service provider. Specifically, the destination mobile terminal 10b can be provided with image information and sound information, image information and character information, or image information, character information and character information. sonorous.
Accordingly, according to the present invention, a destination mobile terminal may be provided with a calling party's picture information, or a calling party's information of one or a combination of a picture information, a sound information, or character information, when the destination mobile terminal receives a telephone call signal in a mobile radio communication network. For example, the destination mobile terminal may be provided with only one image information to represent the face of the calling party; of both image information and character information; or image information, character information, and sound information, simultaneously. Because a caller information is provided, a user of the destination mobile terminal can recognize who is calling. Accordingly, the user of the destination mobile terminal can decide whether to answer the telephone call and, in the course of the telephone call, the user of the destination mobile terminal can display an image of the calling party. Finally, in the event that a user makes a page on his / her own mobile terminal, the user can receive image information, character information and / or sound information registered by him / her. user through their own mobile terminal.
The stated embodiments are merely exemplary and should not be construed as limiting the present invention. The teachings set out can be easily applied to other types of devices. The description of the present invention is intended to be illustrative and not claiming the scope of the claims. Many alternatives, modifications and variants should be apparent to those skilled in the art.
