[Technical field to which the invention belongs]

The present invention relates to a communication method for performing voice and data communication via a wireless telephone network, a mobile terminal device and a gateway device, and in particular, connects to the Internet via the wireless telephone network and communicates voice and data through the communication method. The present invention relates to a communication method, a mobile terminal device, and a gateway device that perform the above in the IP packet format.

[Conventional technology]

With the spread of mobile phones (cellular phones) and PHS (Personal Handyphone System) terminals, communication services using wireless communication systems have become widespread. These mobile phones (cellular phones) and PHS terminals perform wireless communication with wireless base stations, and are connected to a large number of wired communication networks from the base stations to provide communication services.

【0003】

On the other hand, various information services on the Internet have been developed due to the widespread use of the global computer network "Internet". In particular, Internet telephones (IP telephones), which convert telephone voice data into IP packets and communicate via the Internet, are attracting attention by taking advantage of the extremely low communication cost compared to conventional telephone networks. Typically, as shown in FIG. 19, an IP telephone gateway that relays between the voice telephone network and the Internet network is installed in a telephone office, for example, and communication between these gateways is performed via the Internet to make a long-distance call. However, it will be possible to execute only the charge to the nearest telephone office (or the location where the IP telephone gateway is installed).

【0004】

Such an Internet telephone can also be applied to a wireless mobile terminal whose terminal is a cellular telephone or a PHS terminal. For example, as shown in FIG. 20, a router device that manages a plurality of radio base stations is provided, and this router device acts as an IP telephone gateway to realize an Internet radiotelephone communication system that exchanges data with the Internet network. it can.

【0005】

Of course, on the Internet, it is possible to transfer multimedia data in various formats according to standard protocols. For example, voice, still images, moving images, data files of specific applications, etc. can be converted into IP packets and transferred using a single TCP / IP protocol. Therefore, in FIG. 20, by setting a protocol for transmitting TCP / IP packets between the router device, the wireless base station, and the wireless mobile terminal, the multimedia transferred on the Internet at the same time while using the Internet telephone. It becomes possible to exchange data. Specifically, to realize an application that transfers related image data (for example, material or map data) while making a voice call, or receives a related photo as an image while receiving a news clip by voice. Can be done.

【0006】

However, when multimedia communication including the above-mentioned Internet telephone is performed by a wireless mobile terminal, it is generally considered that there are various resource restrictions in a small wireless mobile terminal.

【0007】

For example, even if image data is received, there may be no display device capable of displaying it with sufficient resolution. There is also a restriction that the screen size is small.

【0008】

Also, for example, multimedia data generally has a huge amount of data, and in the worst case, it can occur even when the entire transmitted multimedia data cannot be retained.

【0009】

Further, looking at the environment in which the Internet network or the telephone network is used, in general, wireless mobile terminals often have a worse usage environment than, for example, ordinary fixed PCs. For example, if you are departing from a fixed PC at home, you may have a flat-rate contract for a local phone, or you may be able to use Internet applications more easily on a normal PC (for example, you can clearly hold a lot of Web address information). ) Can occur.

【0010】

[Problems to be Solved by the Invention]

As described above, when using a wireless mobile terminal to provide an Internet phone and an Internet service that handles multimedia data, generally when using a small wireless mobile phone as a terminal, a display that can display image data with sufficient resolution. There were resource restrictions such as the lack of a device, the memory that can hold a large amount of multimedia data, and the inability to install a storage device such as a disk.

【0011】

In addition, wireless mobile terminals may have a poor environment, such as poor application operability and high communication media usage charges, compared to fixed PCs installed at home and notebook PCs that are carried. ..

【0012】

The present invention has been made in consideration of the above circumstances, and provides a communication method, a mobile terminal device, a gateway device, and a communication method that can be operated to supplement the resource shortage and inferior environment of the mobile terminal device. The purpose is to do.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the invention will be described with reference to the drawings.

【0052】

First, the basic configuration of the present embodiment will be described with reference to FIG.

【0053】

FIG. 18 shows an example of the network configuration assumed in the present embodiment and the usage mode of the wireless mobile terminal according to the present embodiment. In FIG. 18, consider a case where the wireless mobile terminal 1 performs some kind of communication with a communication partner (not shown).

【0054】

The wireless mobile terminal 1 has a function of independently performing communication and other processing, but in the present embodiment, in addition to this, a fixed computer 7 installed in a home, an office, or the like (in the present embodiment, a home desktop PC). And / or also has a function of performing communication and other processing in cooperation with a mobile computer 8 (referred to as a notebook PC in this embodiment) carried by a user having the wireless mobile terminal 1 at the same time. ..

【0056】

As a result, it is possible to maximize the advantages such as mobility, convenience, and practicality of the wireless mobile terminal, which may be inferior in terms of computer capability, operating environment, communication cost, and the like.

【0057】

Hereinafter, embodiments of the present invention will be described in more detail.

【0058】

FIG. 1 shows an example of a basic configuration of a network according to an embodiment of the present invention.

【0059】

The wireless network is generally operated by a wireless communication carrier or the like, and the wireless base station 2 (2a to 2m in FIG. 1) accommodates the portable wireless terminal (1a to 1n in FIG. 1), and the portable wireless terminals 1 are connected to each other. Along with servicing calls and servicing calls between the portable wireless terminal 1 and a telephone housed in the telephone network 3, a router device 5 is installed, and voice data transmitted from the wireless mobile terminal 1 by the router device 5 is installed. It provides services for transferring packets containing and other multimedia data to the IP network (for example, the Internet) 4 and for packet transfer from the IP network (for example, the Internet) 4 to the wireless mobile terminal 1.

【0060】

On the other hand, the telephone network 3 is generally operated by a wireless communication carrier or the like, and accommodates telephones (not shown) to provide telephone-to-telephone calls and telephone-portable wireless terminal 1 calls, as well as an Internet telephone gateway 6. It is installed and this Internet telephone gateway 6 provides an Internet telephone service by transferring voice telephone data via an IP network.

【0061】

The Internet telephone gateway 6 is a device for converting voice telephone data into IP packets and transferring them to the Internet when using an Internet telephone, and in this example, it is assumed to be installed in a telephone office. When the user uses an Internet telephone, the access number assigned to the Internet telephone gateway 6 is dialed to make a connection, and the necessary destination data is passed to the Internet telephone gateway 6. The Internet telephone gateway 6 searches for the IP address of the Internet telephone gateway 6 in the vicinity of the communication partner, and makes a connection on the IP network. The Internet telephone gateway 6 of the communication partner makes a call to the other party's telephone and establishes a connection between the ends. In FIG. 1, by using this service, it is possible to make a call between telephones in the telephone network 3, a call between wireless mobile terminals 1, and a call between the telephone and the wireless mobile terminal 1.

【0062】

In establishing a connection using such an Internet telephone gateway 6, it is assumed that the wireless mobile terminals 1a to 1n operate as ordinary wireless telephones and make a call to a nearby Internet telephone gateway 6. In this case, the wireless mobile terminal and the Internet telephone gateway are connected via the telephone network 3, and analog voice is digitized on the Internet telephone gateway 6 and stored in an IP packet and transferred to the IP network.

【0063】

As a format in which voice telephone data is converted into an IP packet, for example, a combination of RTP (Real Time Protocol) and UDP (User Datagram Protocol) can be considered. Figure 2 shows an example of the packet format in this case.

【0064】

In the present embodiment, it is also assumed that the wireless mobile terminal 1 accesses the IP network not via the Internet telephone gateway 6 but via the router device 5 installed upstream of the wireless base station 2. Therefore, if sufficient computing resources can be secured on the wireless mobile terminal 1 side, the processing on the Internet telephone gateway 6 should be performed on the wireless mobile terminal 1 side and the digitized voice packet should be transmitted via the router device 5. It may be. However, this function can be used when the search method of the IP address of the destination gateway and the coding format of the telephone voice data are disclosed by the business operator.

【0065】

That is, in the present embodiment, when transmitting IP voice data to the wireless mobile terminal 1, (1) Make a call via the telephone network 3 via the Internet telephone gateway 6 near the wireless mobile terminal 1.

【0066】

(2) Transfer by IP packet as it is without going through the Internet telephone gateway 6 near the wireless mobile terminal 1, transfer to the wireless mobile terminal 1 via the router device 5, and voice data from the IP packet on the wireless mobile terminal 1. Is taken out, converted to analog, and output. (When the wireless mobile terminal 1 is the transmitting side, similarly, when using the neighboring Internet telephone gateway 6 and when sending it as an IP packet in the own device, it is possible to select the two methods arbitrarily. Can be selected).

【0067】

By the way, as described above, in this system, there are other PCs that cooperate with the wireless mobile terminals 1a to 1n, that is, the desktop PC 7 and the notebook PC 8 in FIG. The desktop PC 7 is a PC installed at the home of a wireless mobile terminal user, and is also connected to the Internet 4. On the other hand, the notebook PC 8 is a PC carried by the user at the same time as the wireless mobile terminal 1, and the wireless mobile terminal 1 can communicate with the notebook PC 8 via the Internet 4 or via a local network using wireless or infrared rays (IrDA, etc.). Note that the operation of the notebook PC 8 via the Internet 4 is basically the same as that of the desktop PC 7, so in the following, the notebook PC 7 will communicate via wireless or a local network using infrared rays (IrDA, etc.). The case will be described.

【0068】

Next, the configuration of the wireless mobile terminal according to the present embodiment will be described.

【0069】

FIG. 3 shows an example of the internal configuration of the wireless mobile terminal of the present embodiment.

【0070】

This wireless mobile terminal includes a wireless communication unit 61, a local network communication unit 62, a voice format processing unit 63, a TCP / IP processing unit 64, an A / DD / A conversion unit 65, a voice input / output processing unit 66, and a packet transfer processing unit. It is equipped with 67, display 68, other input / output devices (not shown), memory, etc. In addition, it is equipped with the functions of ordinary wireless telephones and calculators as needed.

【0071】

The radiotelephone unit 61 is an input / output unit for communicating with a radiotelephone network via any of radio base stations 2a to 2m (for example, selected by radio wave strength), like a normal radiotelephone. On the other hand, the local network communication unit 62 is an interface for communicating with the notebook PC 8 carried by the user of the wireless mobile terminal 1 at the same time by using wireless or infrared rays (IrDA or the like). These communication modules control the IP data transfer process by using the related PC control information described later.

【0072】

The voice format processing unit 63 processes voice telephone data. The voice telephone data received from the wireless telephone network is processed here and sent to the voice input / output processing unit 66.

【0073】

On the other hand, the voice packet data directly received from the IP network 4 is received from the TCP / IP processing unit 64, converted into analog data by the A / DD / A conversion unit 65, and sent to the voice input / output processing unit 66. When data other than audio, such as image data, is received from the IP network 4, it is processed by an appropriate dedicated application in the TCP / IP processing unit 64 and output to the display 68 as needed.

【0074】

The display 68 is attached to the wireless mobile terminal 1, and its output size, resolution, and the like are significantly inferior to those of other desktop PCs and notebook PCs.

【0075】

The packet transfer processing unit 67 transfers transmission / reception data of a specific attribute to the registered desktop PC 7 or notebook PC 8 based on the related PC control information specified in advance.

【0076】

Figure 4 shows a configuration example of the related PC information table 671 that stores the related PC information.

【0077】

This table registers the logical name, communication route (Internet / Local-net), and IP address (in the case of the Internet) of the transfer destination PC.

【0078】

In this example, a desktop PC8 (host name: DESK1, network: via the Internet, address: IP address = 133.196.16.201) installed at home by a wireless mobile terminal user and a notebook PC8 (host name: NOTE2,) carried at the same time. Network: Local connection, Media: IrDA) are registered.

【0079】

A Preference field may be added to the related PC information table shown in FIG. 4, and a plurality of registered related PCs may be prioritized to transfer packets. The related PC information table in Fig. 5 is an example in which NOTE2 is specified to be prioritized for transfer.

【0080】

In addition, when the mobile terminal device operates in an unstable operating environment, an inspection message is periodically sent to each related PC to monitor whether communication is possible with each PC, and the related PC that is temporarily unable to communicate. You may use an operation policy such as not forwarding packets. The related PC information table illustrated in FIG. 6 is a combination of the prioritization in FIG. 5 and the communicable information of each PC. In the case of the specific example of Fig. 6, for example, if both PCs can communicate, NOTE2 is prioritized, but if NOTE2 is out of battery or because it is in the bag, IrDA cannot communicate. Automatically detects that NOTE2 is out of communication and forwards it to DESK1 as an alternative.

【0081】

In this case, the communicability detection module can be easily realized by using the ping program as a higher-level application of TCP / IP, and the detected communicability status should be written in the related PC information table 671. Just do it.

【0082】

In the above, the priority PC is given to the PC in advance, but the PC may be selected by comprehensively considering various characteristics and / or data attributes of each PC.

【0083】

Further, when a plurality of PCs are registered, a plurality of PCs may be allowed to be selected. Alternatively, depending on the conditions, a plurality of PCs may be positively selected. When a plurality of PCs are selected, for example, the same data may be broadcast or multicast, or the roles may be divided among the selected PCs.

【0084】

Next, FIG. 7 shows a configuration example of the transfer data attribute table 672 for specifying what kind of data is to be transferred to the above-mentioned registered related PC (desktop PC7 or notebook PC8 in this example).

【0085】

The data attributes can be controlled from various viewpoints, but in FIG. 7, as an example, the presence or absence of data transfer is specified by the following attributes.

【0086】

(Rule 1) For voice call sessions with attachments of 100KB or more, transfer the attachments to the related PC.

【0087】

(Rule 2) If the size is 100KB or more by ftp, transfer it to the related PC.

【0088】

(Rule 3) For specific applications (here, Internet-CM and Internet-news-clip), this is forcibly output in the own device.

【0089】

(Rule 4) For telephone data that can be used for local calls from a PC installed at home (desktop PC7 in this example), transfer this to that PC and make a call from there.

【0090】

For those that do not correspond to any of the rules or those that are not specified in the applicable rules, the default processing contents according to the data shall be executed. For example, for a voice call session with an attached file of less than 100 KB, the voice is output on the wireless mobile terminal and the attached data is also displayed / saved on the wireless mobile terminal. In a voice call session with an attached file of 100 KB or more, the voice is output on the wireless mobile terminal.

【0091】

Various rules can be considered, and can be appropriately set in consideration of the resource, performance, environment, and other conditions of the wireless mobile terminal, the purpose of use of the user, and the like. Also, the user may be able to select part or all of the rules. These points are the same for the default processing contents.

【0092】

In the following, how the transfer processing is performed for each specified data attribute will be described based on various specific examples.

【0093】

First, some examples of control that will not be transferred to the related PC (special processing is performed in the wireless mobile terminal 1) will be described. This example is related to Rule 3 shown above.

【0094】

FIG. 8 shows an example in which certain image / character data is not stored in the wireless mobile terminal 1 and is not transferred to the related PC, but is only displayed on the wireless mobile terminal 1.

【0095】

The data packet specified as APPL = Internet-CM in the specific example of the third rule in FIG. 7 is commercial data (image, character data) transmitted as an attachment to the voice packet of the Internet telephone. This rule forces the commercial data to be output in real time from the display as it is and discards the data itself for users who think that buffering it with the wireless mobile terminal 1 will only waste memory. Control.

【0096】

In FIG. 8, the data packet carrying the voice data is processed in the order of the wireless communication unit 61, the packet transfer processing unit 67, the TCP / IP processing unit 64, the A / DD / A conversion unit 65, and the voice input / output processing unit 66. , Audio output.

【0097】

On the other hand, the image data which is the attached data is passed to the wireless communication unit 61, the packet transfer processing unit 67, and the TCP / IP processing unit 64, and the TCP / IP processing unit 64 checks, for example, the upper layer protocol identifier, and if the data is found. If APPL = Internet-CM rule is met, display all attached commercial data on display 68.

【0098】

In this case, the analogization process of the voice data packet may be performed on either the wireless mobile terminal 1 side or the Internet telephone gateway 6 side (Fig. 8 is an example performed on the wireless mobile terminal 1 side). ..

【0099】

Next, FIG. 9 shows an example in which voice and image / character data are displayed in synchronization.

【0100】

The data packet specified as APPL = Internet-news-clip in the specific example of the fourth rule in FIG. 7 is news clip data transferred to a medium via an Internet telephone.

【0101】

This service can display, for example, photographic images and materials related to news manuscripts by outputting images and character data attached to a voice packet and transferred in synchronization with the voice. Specifically, for example, the synchronization tag data of the voice packet and the attached data is added to the data format of the news clip, and the sound and the image are output while being synchronized according to the synchronization tag data.

【0102】

In this case as well, the analogization process of the voice data packet can be performed on either the wireless mobile terminal 1 side or the Internet telephone gateway 6 side, but FIG. 9 shows the case where the wireless mobile terminal 1 side is used. explain.

【0103】

In FIG. 9, the data packet carrying the voice data is processed in the order of the wireless communication unit 61, the packet transfer processing unit 67, the TCP / IP processing unit 64, the A / DD / A conversion unit 65, and the voice input / output processing unit 66. On the other hand, the image data which is the attached data is processed in the order of the wireless communication unit 61, the packet transfer processing unit 67, and the TCP / IP processing unit 64, and is displayed on the display 68.

【0104】

Here, since the size of the attached image data is generally larger than that of the audio data, a delay occurs in the transfer. Therefore, if the TCP / IP processing unit 64 checks the upper layer protocol identifier and finds that it matches the APPL = Internet-news-clip rule, the audio output is temporarily stopped and all the necessary synchronized display image data is moved wirelessly. The arriving voice data packet may be converted and buffered (for example, by the A / DD / A converter 65) until it arrives at the terminal 1 and is displayed for a predetermined time.

【0105】

In FIG. 9, an example in which the analogization process of the voice data packet is performed on the wireless mobile terminal 1 side has been described. However, assuming that the analogization process of the voice data packet is performed on the Internet telephone gateway 6 side as shown in FIG. The voice packet is the Internet telephone gateway 6 (TCP / IP processing unit 164, A / DD / A conversion unit 165, voice format processing unit 163), and the synchronized data is the wireless mobile terminal 1 (TCP / IP processing unit 64). So, each will be processed.

【0106】

In this case, the voice data packet is buffered by the Internet telephone gateway 6, and the voice is output when the wireless mobile terminal 1 receives a message notifying that the processing of the synchronization data with the predetermined synchronization data tag is completed. You just have to do.

【0107】

Next, some examples of control for transferring a part or all of the received data to the related PC will be described. This example is related to rules 1 and 2 shown above.

【0108】

FIG. 11 shows an example of transferring data corresponding to a certain condition to a related PC without displaying or saving it on the wireless mobile terminal 1.

【0109】

These two rules, (Rule 1) For voice call sessions with attachments of 100KB or more, transfer the attachments to the related PC.

【0110】

(Rule 2) If the size is 100KB or more by ftp, transfer it to the related PC. Is a control regarding the amount of data to be transferred.

【0111】

Since the storage capacity of the wireless mobile terminal 1 side is generally limited in this control, the attached data is registered for the session (Internet voice call, e-mail, ftp itself) containing the attached data exceeding a certain value. It is intended to be transferred to the related PC.

【0112】

For example, as shown in FIG. 11, when the image data of the map is attached to the voice call, the voice is output by the wireless mobile terminal 1, but the display 68 has sufficient resolution to understand the map. Since there is no image data, the image data is transferred to, for example, a notebook PC 8 via a local net without being displayed or saved on the wireless mobile terminal 1 side.

【0113】

The transferred image data may be later transferred to the PC or another computer for display. For example, when the image data is transferred to the notebook PC 8, the image data is displayed on the notebook PC 68 during a call. Is also possible.

【0114】

Next, in the example described in FIG. 11, a predetermined data size was used as a criterion for deciding whether to transfer the received data to another computer, but as shown in FIG. 12, the wireless mobile terminal 1 side is currently actually used. The storage capacity available to the user may be taken into consideration when deciding whether or not to transfer the data.

【0115】

For example, if the available memory amount data x (641 in the figure) is held and the data size of the transferred ftp data packet is x or less, or x is multiplied by the coefficient k (0 <k <1). If it is less than or equal to the value, it can be stored in the memory in the own device, and if not, it can be controlled to be transferred to the notebook PC 8 via the local net, for example.

【0116】

Further, in the examples described in FIGS. 10 and 11, the data once received by the own device is transferred to the notebook PC 8, but as shown in FIG. 13, it can also be transferred to the desktop PC 7 via the Internet. is there.

【0117】

Further, in this case, instead of taking the procedure of transferring the data once received by the wireless mobile terminal 1 to the desktop PC 7, the transfer destination data is sent to the source when the session specified in the transfer data attribute table 672 starts. By notifying, it is possible to avoid data buffering on the wireless mobile terminal 1 side and use the system as if the data was transferred to the desktop PC 7 as a background job on the Internet. ..

【0118】

By the way, in the case of a communication mode in which voice data and its attached data are transferred to the Internet telephone gateway 6 and the voice is converted to analog there, a copy of the transfer data attribute table 672 is transferred to the Internet telephone gateway 6 as shown in FIG. It is also possible to control the packet to be forwarded to the desktop PC 7 as soon as it is passed and a matching data string is received.

【0119】

Also in this case, both the related PC information table 671 and the transfer data attribute table 672 are registered in the Internet telephone gateway 6 on the station side, and when the data matching the attribute table is received, the IP is not converted to analog. Control to transfer the packet as it is to the desktop PC7.

【0120】

For example, it can be applied when all news clip data (delivered via the Internet phone) is transferred to the desktop PC7 side and stored in IP format while moving.

【0121】

Next, an example of control in consideration of cost will be described.

【0122】

As shown in FIG. 16, for batch transmission processing, for example, the transfer destination is close to the desktop PC 7 in terms of network, or the connection fee is high when the wireless mobile terminal 1 is used, so that the wireless mobile terminal 1 is directly connected. In some cases, it is more advantageous in terms of charges to transfer the data to the desktop PC 7 via the Internet 4 once and then resend it to the final destination rather than sending it.

【0123】

The forwarding rule in this case is, for example, IF Sent-packet-size> = 50MB, forward to DESK1, then send to dest. Is. According to this rule, all data transfer of 50MB or more is not performed from the wireless mobile terminal 1, but is once transmitted to the desktop PC 7 and then transmitted again from there.

【0124】

In addition, control as in Rule 4 is also possible.

【0125】

That is, as shown in Fig. 17, when calling the area code (for example, 044) by Internet telephone and receiving the information service, if it is from the desktop PC7, the flat rate of the local call can be used. If the information acquisition is not urgent, for example, the call to 044 city is not made from the wireless mobile terminal 1, and only the necessary dialing data is transferred to the desktop PC 7 via the Internet 4. Receive information service data on the desktop PC7 side. Then, the data received by the desktop PC 7 is received again on the wireless mobile terminal 1 side via the Internet 4 ~ router device 5 ~ wireless base station 2, and this is D / A converted and formatted to make a desired voice call. You can receive the service at a low price.

【0126】

In the following, the data attributes used when referencing the transfer data attribute table 672 will be described.

【0127】

Control that changes the processing of received information based on the information (router) described in the transfer data attribute table 672 in the wireless mobile terminal 1 of the present embodiment, for example, attached data in a voice session to which attached data is attached. In order to realize control such as playing back voice information on its own device while transferring data to Note 8 connected by IrDA etc., for each packet received via the Internet 4, the type of information contained in the packet It is assumed that a data attribute tag for identifying is attached. Various methods can be considered for this, for example, a well-known markup language such as HTML or XML may be used.

【0128】

However, not all information on the Internet 4 has data attribute tags uniformly attached by such a markup language. For example, some websites may use a markup language that cannot be used due to resource restrictions on the wireless mobile terminal 1. Further, as in the configuration shown in FIG. 17, when the voice session is set via the Internet 4 and the (city) telephone network 3, the voice session is passed through the (city) telephone network 3 as an analog signal. The data attribute tag is not always attached to the incoming voice call data.

【0129】

Therefore, the wireless mobile terminal 1 and the wireless mobile terminal 1 can process information to which the data attribute tag is not attached and information to which the data attribute tag of a type that cannot be interpreted by the wireless mobile terminal 1 is attached. The desktop PC 7 that communicates via the Internet 4 may function as follows.

【0130】

That is, in the configuration shown in FIG. 17, the desktop PC 7 makes a call to the telephone number instructed from the wireless mobile terminal 1, and when the desired analog voice information is obtained, the analog voice is A / D Convert and convert to packet. At this time, the desktop PC 7 simultaneously attaches a data attribute tag indicating voice data to the information. The packet to which the data attribute tag is attached is transferred to the wireless mobile terminal 1 via the Internet 4, the router device 5, and the wireless base station 2. The wireless mobile terminal 1 refers to the transfer data attribute table 672 using the value of the data attribute tag attached to the packet, and presents the message to the user on its own device or transfers the message to the notebook PC 8. To determine. This method is not only applicable to stored voice data such as information services, but can also be used when real-time voice, that is, ordinary telephone service is used on a notebook PC 8 via a wireless mobile terminal 1. Is.

【0131】

If the charge for accessing the Internet 4 from the desktop PC 7 is lower than the charge for accessing the Internet 4 from the wireless mobile terminal 1, the following functions can be provided to the user in the configuration shown in FIG. It is possible to provide the user with a price advantage.

【0132】

That is, it is a function that the desktop PC 7 collects the information of the Web page group that the user suddenly needs on the go instead of the user who has a high usage fee. The user instructs the desktop PC 7 to use the notebook PC 8 or the wireless mobile terminal 1 to instruct the required Web pages via the Internet 4. The desktop PC 7 sequentially accesses the Web pages according to the given instructions, and collectively sends the information back to the wireless mobile terminal 1 or the notebook PC 8 via the Internet 4. At this time, if the specified Web page uses a data attribute tag that is not supported by the wireless mobile terminal 1, the desktop PC 7 has a data attribute tag that the wireless mobile terminal 1 supports. It may be converted to.

【0133】

Next, in the present embodiment, the final destination (whether or not to transfer to the related PC) of the received packet is determined based on the assigned data attribute tag. According to the following method, the data is determined. The final destination can be determined even for the packet flow to which the attribute tag is not attached. This method is used, for example, when the Internet 4 to which the wireless mobile terminal 1 is connected employs flow rate billing and the telephone network 3 to which the desktop PC 7 is connected employs a flat rate. It is possible to reduce the communication charges that must be borne by the user.

【0134】

In the configuration shown in FIG. 17, when voice communication is performed from the wireless mobile terminal 1 or the notebook PC 8, if the predetermined conditions, for example, the charge system is as described above, the connected telephone of the desktop PC 7 Communication shall be performed via network 3. At this time, the wireless mobile terminal 1 or the notebook PC 8 first sets a voice communication channel, for example, a voice session by RTP, toward the desktop PC 7 via the wireless base station 2, the router device 5, and the Internet 4. Next, the wireless mobile terminal 1 or the notebook PC 8 makes a voice connection on the telephone network 3 to the communication partner performing voice communication with the desktop PC 7 via, for example, the wireless base station 2, the router device 5, and the Internet 4. Set. After that, the desktop PC 7 transfers the information flowing from the voice communication channel between the wireless mobile terminal 1 or the notebook PC 8 to the voice connection on the telephone network 3 and the information flowing from the voice connection on the telephone network 3. To the voice communication channel between the wireless mobile terminal 1 or the notebook PC 8, respectively. At this time, in the wireless mobile terminal 1, by referring to the port number of each received packet, it can be identified that the packet is received from the voice communication channel set with the desktop PC 7, and further, the packet can be identified. It can be estimated that the voice information is being transferred. Based on this estimation, the wireless mobile terminal 1 defines the final destination (whether or not to transfer the packet to the related PC) of the voice information in the transfer data attribute table 672 of the packet received from the voice channel. Process according to the contents of.

【0135】

Next, in the present embodiment, according to the following method, the user of the wireless mobile terminal 1 can accept an incoming call for voice communication via the desktop PC 7. As a result, when the charge of the wireless communication network is higher than the charge of the voice network to which the desktop PC 7 is connected, the communication partner receives an incoming call from the communication partner who communicates with the user of the wireless mobile terminal 1. Can reduce the usage fee that must be paid by.

【0136】

In the configuration shown in FIG. 17, if there is an incoming call from the telephone network 3 connected to the desktop PC 7, the desktop PC 7 answers the incoming call and communicates by voice connection via the telephone network 3. Set up the device. Further, the desktop PC 7 sets a first voice channel to the wireless mobile terminal 1 via the Internet 4, the router device 5, and the wireless base station 2, for example, a voice session by RTP.

【0137】

When the voice channel is set, the wireless mobile terminal 1 refers to the transfer data attribute table 672, and whether the final transfer destination of the voice information (whether or not to transfer to the related PC) is the wireless mobile terminal 1. Know if it is a notebook PC8. If it is a notebook PC 8, the wireless mobile terminal 1 further sets a second voice channel with the notebook PC 8.

【0138】

After that, the desktop PC 7 transfers information between the above voice connection and the first voice channel, and the wireless mobile terminal 1 sets the second voice channel, the first voice channel and the second voice channel. Information is transferred to and from each. At this time, in the wireless mobile terminal 1, by referring to the port number of the received packet, it is possible to know whether or not the packet belongs to the first voice channel, and it belongs to the first voice channel. By presuming that all packets are transferring voice information, it becomes possible to process the voice information by the method specified by the transfer data attribute table 672. That is, in this case, it is not necessary to add a data attribute tag to the packet on the first voice channel, and when the Internet is performing flow rate billing, the user of the wireless mobile terminal 1 must pay further. It becomes possible to reduce the charge.

【0139】

By the way, conventionally, when using an Internet telephone and an Internet service that handles multimedia data using a wireless mobile terminal, when the wireless mobile phone is used as a terminal, a storage device that retains the display resolution of image data and data, etc. , There was a limitation on the resources that can be installed. In this respect, desktop PCs and portable notebook PCs installed in homes and the like have advantages such as more resources, better application operability, and lower communication costs.

【0140】

Therefore, in the present embodiment, a desktop PC or a portable notebook PC installed in a home or the like is linked to a wireless mobile terminal, and the method of linking is controlled according to the data attribute, or according to the data attribute. The processing in the wireless mobile terminal is controlled.

【0141】

As a result, for example, when the received image data requires a high-resolution display device, or when it is not necessary to view the contents while moving for the time being, the received image data can be stored in the memory of the wireless mobile terminal or the wireless mobile terminal. It can be controlled to transfer to a desktop PC via the Internet as it is without displaying it on the side, or to transfer to a notebook PC carried at the same time via a wireless / infrared local network.

【0142】

In addition, for example, the user interface of the wireless mobile terminal can be improved by uploading the URL data stored in the mobile notebook PC to the wireless mobile terminal at any time and caching it in the address register of the original Web browser for operation. It can also be done user-friendly.

【0143】

Also, for example, if the other party of the IP phone can make a local call from the location of the desktop PC, the data is once transferred to the desktop PC installed at home or the like via the Internet, and then the call is made. It is possible to control so as to reduce the communication charge by performing the control.

【0144】

In the explanation so far, the voice data to which the attached data is attached is output as voice by the wireless mobile terminal 1, and the attached data is transferred to the related PC. However, for example, the voice data is very large. When the attached data is a small amount of character data (for example, a list of song titles) with a large size data (for example, several songs over a long period of time), the attached data is displayed on the wireless mobile terminal 1 and voice data. (Or voice data and attached data) may be transferred to the related PC.

【0145】

Further, the wireless mobile terminal 1 may be equipped with only one of a function of using the Internet telephone gateway and a function of processing in the own device.

【0146】

In addition, the wireless mobile terminal 1 can use only one of a computer such as a desktop PC installed at home and a mobile computer such as a notebook PC carried by a user having the wireless mobile terminal 1 at the same time. May be.

【0147】

Further, the wireless mobile terminal 1 is not limited to the one having a so-called mobile phone type outer shape, and may have any outer shape. In addition, when considering the cooperation between the wireless mobile terminal 1 and the desktop PC or notebook PC, the difference between the wireless mobile terminal 1 and the desktop PC or notebook PC is relative. For example, some notebook PCs have a wireless function. Sometimes it can function as a wireless mobile terminal 1.

【0148】

The above functions can also be realized as software.

【0149】

Further, the present embodiment is readable by a computer in which a program for causing a computer to perform a predetermined means (or for making the computer function as a predetermined means, or for causing a computer to perform a predetermined function) is recorded. It can also be implemented as a recording medium.

【0150】

The present invention is not limited to the above-described embodiment, and can be implemented with various modifications within the technical scope thereof.

【0151】

[Effect of the invention]

According to the present invention, by linking the mobile terminal device with another computer, it is possible to perform an operation that complements the inferior points of the mobile terminal device in terms of the ability as a computer, the operating environment, the communication cost, and the like. , It is possible to maximize the advantages of the mobile terminal device such as mobility, convenience, and practicality.
