[Configuration Example of SIP Server 1]
First, the configuration of the SIP server 1 used in the telephone systems A and B of this embodiment will be described. FIG. 3 is a block diagram for explaining a configuration example of the SIP server 1. As shown in FIG. 3, the SIP server 1 includes a connection terminal 101 for an IP network included in the network 6, an IP network interface (hereinafter abbreviated as IP network I / F) 102, and a packet decomposition / generation unit. 103. The SIP server 1 includes a telephone network interface (hereinafter abbreviated as a telephone network I / F) 104 and a connection terminal 105 to a public switched telephone network (hereinafter simply referred to as a telephone network) included in the network 6. And an address management database (hereinafter abbreviated as address management DB) 106. Furthermore, the SIP server 1 includes a LAN interface (hereinafter abbreviated as LAN I / F) 107, a connection terminal 108 to the LAN 2, and a control unit 110.

  The control unit 110 controls each unit of the SIP server 1 according to this embodiment, and as shown in FIG. 3, a CPU (Central Processing Unit) 111, a ROM (Read Only Memory) 112, a RAM (Random Access Memory). ) 113 is a microcomputer configured by being connected through the system bus 114. Here, the CPU 111 executes a program stored in the ROM 112 to generate a control signal for controlling each unit and supply the control signal to each unit or process information from each unit. . As described above, the ROM 112 stores and holds various programs executed by the CPU 111 and various data necessary for processing.

  The RAM 113 is mainly used as a work area, such as temporarily storing intermediate results of processing. Although not shown, for example, a nonvolatile memory such as an EEPROM (Electrically Erasable and Programmable ROM) or a flash memory is provided, and data to be retained even when the power is turned off, for example, various setting parameters and functions are improved. It is possible to store and hold new programs provided for the purpose.

  The connection terminal 101 constitutes a connection end portion of the network 6 to the IP network. The IP network I / F 102 receives a packet supplied through the IP network, converts it into a packet in a format that can be processed by itself, and supplies the packet to the control unit 110. The IP network I / F 102 converts a packet to be transmitted supplied through the control unit 110 into a packet in a transmission format, and transmits the packet to the IP network.

  The connection terminal 105 constitutes a connection end portion to the telephone network in the network 6. The telephone network I / F 104 receives data supplied through the telephone network, converts it into data in a format that can be processed by itself, and supplies the data to the control unit 110. Further, the telephone network I / F 104 converts data to be transmitted supplied through the control unit 110 into data in a transmission format, and transmits the data to the telephone network.

  The connection terminal 108 constitutes a connection end to the LAN 2. The LAN I / F 107 receives a packet supplied via the LAN 2, converts it into a packet in a format that can be processed by the own device, and supplies the packet to the control unit 110. The LAN I / F 107 converts a packet to be transmitted supplied through the control unit 110 into a packet in a format for transmission, and transmits this to the LAN 2.

  The packet decomposition / generation unit 103 performs packet decomposition and generation, and is mainly used when a call is made between a terminal device connected to the telephone network and the IP telephone terminal 4 under the SIP server 1. Decompose and generate packets of data to be sent and received. Specifically, a packet to be transmitted to the terminal device connected to the telephone network from the IP telephone terminal 4 or the like connected to the SIP server 1 through the LAN 2 is supplied to the control unit 110 through the connection terminal 108 and the LAN I / F 107. The The packet is supplied from the control unit 110 to the packet disassembly / generation unit 103, where the packet is disassembled, and then transmitted to the telephone network through the telephone network I / F 104 and the connection terminal 105, and is transmitted to the intended destination. The

  In addition, data from the terminal device connected to the telephone network to the IP telephone terminal 4 connected to the SIP server 1 through the LAN 2 is supplied to the control unit 110 through the connection terminal 105 and the telephone network I / F 104. The data is supplied from the control unit 110 to the packet decomposing / generating unit 103, where the data is converted into a packet in a predetermined format, and then sent to the LAN 2 through the LAN I / F 107 and the connection terminal 108 to be a target IP telephone terminal 4 etc.

  Packets are transmitted and received between the terminal connected to the IP network and the IP telephone terminal 4 connected to the SIP server 1 via the LAN 2. For this reason, the packet decomposition / generation unit 103 does not perform packet decomposition or generation, and the IP network I / F 102 and the LAN I / F 107 prepare and transmit the data format as it is. Similarly, since packets are transmitted and received between the IP telephone terminals 4 connected to the SIP server 1 via the LAN 2, the packet disassembly / generation unit 103 does not disassemble or generate the packet, and the LAN I / F 107. Packets are sent and received through

  The address management DB 106 is connected to the IP network or the LAN 2 in order to realize the registrar server function, and stores and holds address information about terminal devices that may be called through the SIP server 1. Specifically, the control unit 110 of the SIP server 1 receives registration requests (register requests) from various terminal devices connected thereto through the IP network I / F 102 and the LAN I / F 107. In this case, the control unit 110 extracts address information such as a URI (Uniform Resource Identifier) and an IP address included in the received request. Then, the control unit 110 registers the extracted address information in the address management DB 106 or updates the registration information in the address management DB 106 using the extracted address information.

  In this way, the information registered and managed in the address management DB 106 is referred to, and the communication destination requested from the IP telephone terminal 4 or the like connected to the own device through the LAN 2 is surely specified. Then, the SIP server 1 realizes a function as a proxy server that transfers information (packet data) to be transmitted to the specified partner. The information registered and managed in the address management DB 106 is also used for determining incoming calls to the IP telephone terminal 4 or the like connected to the own device through the LAN 2.

  FIG. 4 is a diagram for explaining a configuration example of management information (database) formed in the address management DB 106.

In the address management DB 106 of the SIP server 1 of this embodiment, as shown in FIG. 3, for the IP telephone terminal 4 connected to the SIP server 1 via the LAN, in addition to the URI and IP address, the MAC (Media Access Control) Also manages addresses and extension numbers.

  Assume that the SIP server 1 accepts a call origination request (call request) from the IP telephone terminal 4 of the telephone system of this embodiment to a terminal device connected to the IP network. In this case, the control unit 110 of the SIP server 1 specifies a target destination terminal device based on the management information of its own address management DB 106, and transfers a message to the specified terminal device. . Further, it is assumed that the SIP server 1 receives an incoming call request (outside line incoming call) to the IP telephone terminal 4 connected to the LAN 2 through the network 6 such as an IP network or a telephone network. In this case, the control unit 110 of the SIP server 1 receives the transmitted message and sends it to the own system.

  Even if the incoming call is an outside line, for example, in the case of an individual incoming call (incoming call specifying a destination IP phone terminal) or an extension call between IP phone terminals connected to the SIP server 1 via LAN, the SIP server 1 specifies the destination and notifies the incoming call. That is, in this case, the control unit 110 of the SIP server 1 identifies the target IP telephone terminal 4 on the basis of the management information in its own address management DB 106, and for this identified IP telephone terminal 4 , Perform message forwarding.

  When an IP telephone number is used for outgoing calls, although not shown in FIG. 1, a gateway or DNS (Domain Name System) connected to the IP network is used to make a URI from the IP telephone number. Are retrieved and used. Similarly, when a call is made from the other party to the IP telephone terminal 4 constituting the telephone system of this embodiment using the IP telephone number, a gateway or DNS connected to the IP network is used. Then, the URI or the like is searched from the IP phone number and used.

  As described above, the SIP server 1 of this embodiment includes the packet decomposition / generation unit 103 and the address management DB 106, and relays messages between terminals connected to various networks to which the SIP server 1 is connected. Is something that can be done. Therefore, the SIP server 1 of this embodiment can perform connection between external lines and internal lines, connection between internal lines, and notify the subordinate IP telephone terminal 4 of the usage status of communication lines. .

  In addition, the control unit 110 can grasp a communication line in use or an empty communication line through the IP network I / F 102, the telephone network I / F 104, and the LAN I / F 107 so that the circuit can be appropriately exchanged. ing. In addition, the control unit 110 forms control information for controlling lighting and extinguishing of LEDs and the like to be supplied for each IP telephone terminal 4 connected through the LAN 2 according to the grasped usage state of the communication line. The control information is transmitted to the LAN 2 through the LAN I / F 107 and the connection terminal 108 and transmitted to each IP telephone terminal 4 and the like.

  In FIG. 3, the packet decomposition / generation unit 103 is shown as an independent circuit part, but the present invention is not limited to this. The packet disassembly / generation unit 103 can of course be realized as a function of the control unit 110 by a program executed by the control unit 110.

In addition, it is also possible to indicate that a call is being made in various display modes in which characters “calling” are blinkingly displayed at any position on the display screen 524G.

  On the other hand, when receiving the INVITE message from the originating IP telephone terminal 4A, the destination IP telephone terminal 4B first returns a response “200 OK” indicating that the INVAIT message has been received (step S13). Then, the destination IP telephone terminal 4B extracts the URL indicating the location of the target e-mail information included in the received INVITE message, and provides this to the mobile phone terminal 5B connected to its own device. An instruction is given to display (step S14). The processing in step S14 is performed through the external I / F 412 and the external terminal 411 by the function of the control unit 430 and the terminal display control unit 422 of the IP telephone terminal 4B.

  Then, in the mobile phone terminal 5B that has received the URL display instruction, the display information processing unit 512 functions to display the URL instructed to be displayed from the IP phone terminal 4B on the display screen 524G of the display 524 through the display controller 523. (Step S15). In this case, on the display screen 524G of the display 524 of the cellular phone terminal 5B, as shown in FIG. 9B, a URL indicating the storage location (location) of the e-mail information is displayed together with a message for prompting reference to the e-mail information. The

  In the case of this example, a predetermined operation is performed such that the cursor is positioned on the display portion of the URL and selected, or the determination key is pressed when the URL is highlighted on the display screen. As a result, the control unit 540 functions to access the storage location specified by the URL and download and display the electronic mail information that is required to be referenced.

  For this reason, it is assumed that the control unit 540 of the mobile phone terminal 5B receives a predetermined operation input for selecting a URL displayed on the display screen 524G of the display 524 through the operation input unit 521. In this case, the control unit 540 forms a request for provision of target e-mail information using the URL, and transmits the request to the Web service server 8 through the transmission signal processing unit 503, the telephone communication unit 502, and the transmission / reception antenna 501. (Step S16). That is, the process of step S16 is a process in which the mobile phone terminal 5B accesses the Web service server 8 using the URL provided from the transmission source through the mobile phone network and requests the provision of the target e-mail information. is there.

  In response to this, the Web service server 8 provides the requested electronic mail information to the requesting mobile phone terminal 5B using the URL (step S17). In the mobile phone terminal 5B that receives the provision of the e-mail information, the control unit 540 and the display controller 523 function, and the e-mail information from the Web service server 8 is displayed on the display screen of the display 524 (step S18). As a result, the user of the destination IP telephone terminal 4B can view (view) the electronic mail information that the caller has requested to see through his / her mobile phone terminal 5B.

  The control unit 540 of the mobile phone terminal 5 functions without waiting for the user's operation, automatically accesses the Web service server 8 using the URL from the IP phone terminal 4B, and stores the stored e-mail. Information can be downloaded and displayed.

  Thereafter, when the user of the destination IP telephone terminal 4B performs an off-hook operation such as lifting the handset 440 of the IP telephone terminal 4B, the on-hook / off-hook detection unit 406 detects that the user has entered the off-hook state, and the control unit 430 Will be notified. The control unit 430 forms an incoming response message, sends it to the SIP server 1B through the LAN I / F 402 and the connection terminal 401, and sends it to the caller from the SIP server 1B (step S19).

  As a result, an incoming call response is transmitted to the source IP telephone terminal 4A, and a communication path (communication line) is connected between the source IP telephone terminal 4A and the destination IP telephone terminal 4B to perform a call. (Step S20). As described above, the same electronic mail information is displayed on the display screen 524G of the display 524 of the caller mobile phone terminal 5A and the display screen 524G of the display 524 of the callee mobile phone terminal 5B. As a result, the user of the IP telephone terminal 4A and the user of the IP telephone terminal 4B can make a call while viewing (confirming) the same electronic mail information.

  Here, as described with reference to FIG. 7 and FIG. 8, after displaying the e-mail information that is requested to be referred to in the destination mobile phone terminal 5 </ b> B, a response is made to the IP phone terminal 4 </ b> B. Although described as an operation, the present invention is not limited to this. For example, after the process of step S15, an incoming call response is made through the IP telephone terminal 4B (step S19), and the communication path is connected to make a call (step S20). Thereafter, the processing of step S16 to step S18 may be performed to display the e-mail information on the mobile phone terminal 5B.

[Display information change processing]
As described with reference to FIGS. 7 to 9, after the communication path is connected and a call is started, information to be viewed through the mobile phone terminals 5 </ b> A and 5 </ b> B may be changed to, for example, a web page. Even in such a case, if it is possible to mutually communicate with the other party of the call what kind of information has been viewed, the display can be viewed even during the call. Information can be shared. Therefore, in the telephone system of this embodiment, the location of the display information after the change can be notified using an INVITE message transmitted and received during a call.

  FIG. 10 is a sequence diagram for explaining an operation (process) when information indicating the location of the display information after the change is transmitted and received when the display information is changed during the call. As shown in the upper end side of FIG. 10, the communication path between the caller IP telephone terminal 4 </ b> A and the callee IP telephone terminal 4 </ b> B by the operations (processes) of the sequence diagrams shown in FIGS. 7 and 8 described above. Is connected and a call is started (step S20).

  Then, it is assumed that it is necessary to confirm the contents of a predetermined web page at both the caller and the callee during a call. At this time, it is assumed that the transmission source user starts up a browser that is web page browsing software in the mobile phone terminal 5A and displays the predetermined web page on the display screen 524G of the display 524 (step S31). . As described above, when the display information is changed, the information notification processing unit 511 cooperates with the control unit 540 and uses the URL of the Web page displayed on the display 524 as the IP telephone terminal 4A to which the own device is connected. (Step S32).

  The IP telephone terminal 4A transmits an INVITE message to the connection destination of the communication path at every predetermined timing in order to confirm that the communication path is connected. Therefore, the outgoing call processing unit 421 of the IP telephone terminal 4A describes the URL of the Web page to be newly displayed in a predetermined area of the INVITE message, and transmits this to the connection destination of the communication path. (Step S33). Thereby, the URL indicating the location of the Web page displayed on the display 524 of the mobile phone terminal 5A on the IP phone terminal 4A side is notified to the IP phone terminal 4B which is the connection destination of the communication path. The IP telephone terminal 4B that has received the INVITE message returns a response (200 OK) indicating that the INVITE message has been received. Thereby, it can confirm that the communication path is mutually connected.

  Then, the IP phone terminal 4B that has received the INVITE message functions as the terminal display control unit 422 to provide the URL included in the INVITE message to the mobile phone terminal 5B connected to the own device and display it. Is instructed (step S34). In response to the instruction, the mobile phone terminal 5B displays the URL, for example, in the manner shown in FIG. 9B, and prompts the display of the Web page specified by the URL (step S35).

  Then, it is assumed that the control unit 540 of the mobile phone terminal 5B receives a predetermined operation input for selecting a URL displayed on the display screen 524G of the display 524 through the operation input unit 521 of the mobile phone terminal 5B. In this case, the control unit 540 activates the browser, accesses the Web page specified by the URL through the transmission / reception signal processing unit 503, the telephone communication unit 502, and the transmission / reception antenna 501, and sends the Web page to the display 524 of the own device. It is displayed (step S36). As a result, the same web page as the web page displayed on the mobile phone terminal 5A on the IP phone terminal 4A side can be viewed on the IP phone terminal 4B side.

  In addition, another Web page may be referred to in the mobile phone terminal 5B connected to the IP phone terminal 4B that is the side on which the call is placed (the incoming side). For example, in the mobile phone terminal 5B, the control unit 540 of the mobile phone terminal 5B functions in response to an instruction input from the user received through the operation input unit 521, and another Web page is displayed on the display screen 524G of the display 524. (Step S37). In this case, under the control of the control unit 540, another target web page is accessed through the transmission / reception signal processing unit 503, the telephone communication unit 502, and the transmission / reception antenna 501. Then, the other Web page is displayed on the display screen 524G of the display 524 through the control unit 540 and the display controller 523.

  In this case, the information notification processing unit 511 of the mobile phone terminal 5B cooperates with the control unit 540 to notify the URL of another Web page displayed on the display 524 to the IP phone terminal 4B to which the own device is connected. (Step S38). Thereby, the IP telephone terminal 4B can recognize that another Web page is displayed on the mobile telephone terminal 5B connected to the own apparatus.

  In the IP telephone terminal 4B, the outgoing call processing unit 421 functions, for example, the URL of the Web page to be newly displayed is described in, for example, user information of the INVITE message, and this is indicated to the connection destination of the communication path. (Step S39). Thereby, the URL indicating the location of the Web page displayed on the display 524 of the mobile phone terminal 5B on the IP phone terminal 4B side is notified to the IP phone terminal 4A that is the connection destination of the communication path. The IP telephone terminal 4A that has received the INVITE message returns a response (200 OK) indicating that the INVITE message has been received. Thereby, it can confirm that the communication path is mutually connected.

  When the IP phone terminal 4A receives the INVITE message, the terminal display control unit 422 functions to provide the URL included in the INVITE message to the mobile phone terminal 5A connected to the own device and display it. (Step S40). In response to the instruction, the mobile phone terminal 5A displays the URL, for example, in the form shown in FIG. 9B, and prompts the display of the Web page specified by the URL (step S41).

  Then, it is assumed that the control unit 540 of the mobile phone terminal 5A receives a predetermined operation input for selecting a URL displayed on the display screen 524G of the display 524 through the operation input unit 521 of the mobile phone terminal 5A. In this case, the control unit 540 activates the browser, accesses the Web page specified by the URL through the transmission / reception signal processing unit 503, the telephone communication unit 502, and the transmission / reception antenna 501, and sends the Web page to the display 524 of the own device. Displayed (step S42). Thereby, also on the IP telephone terminal 4A side, the same Web page as the Web page displayed on the mobile phone terminal 5B on the IP telephone terminal 4B side can be browsed.

  Thus, during a call, each time the display information displayed on the mobile phone terminals 5A and 5B connected to the IP phone terminals 4A and 4B changes, the URL indicating the location of the display information is exchanged. The same display image can be viewed. Thus, even during a call, the target Web page can be displayed by receiving the URL of the target display image without manually entering the URL.

  Here, the case where a Web page is displayed has been described as an example, but the present invention is not limited to this. As described with reference to FIGS. 7 and 8, the URL indicating the storage location of the electronic mail information stored in the Web service server 8 using the mobile phone terminals 5 </ b> A and 5 </ b> B is set to the IP connected to the communication path. Notification can also be made between the telephone terminal 4A and the IP telephone terminal 4B.

[Use history information]
As described above with reference to FIG. 7, in the telephone system of this embodiment, e-mail information desired to be viewed together with the other party of the call during a call is uploaded to the Web service server 8. Then, the target destination can view the electronic mail information uploaded by the destination of the call by downloading it using the notified URL. Then, based on the e-mail information stored in the Web service server 8, history information of e-mail information including a destination, a transmission date / time, a subject, and the like can be formed.

  Further, in the telephone system of this embodiment, when a call is made in a state where the e-mail information is displayed, the e-mail information can be addressed without inputting or selecting a telephone number. You can make a phone call. For this reason, at the time of making such a call, the telephone number of the other party who made the call, the date and time of the call, the name and subject of the displayed e-mail address, etc. are stored in the EEPROM 434 of the IP telephone terminal 4 or the like. Keep it. Thereby, the outgoing call history can be formed in the EEPROM 434 of the IP telephone terminal 4.

  Further, at the time of transmission in a state where the electronic mail information is displayed, the subject and the transmission date and time of the displayed electronic mail information are described in, for example, DisplayName of the INVITE message. In this way, the subject name and transmission date and time can be notified to the destination (incoming destination) IP telephone terminal 4 at the time of transmission. Then, also in the IP telephone terminal 4 of the other party (destination) that made the call, the telephone number of the caller included in the received INVITE message, the subject and the transmission date / time described in the DisplayName of the INVITE message are extracted. . The extracted information is stored and held in the EEPROM 434 of the IP telephone terminal 4. As a result, the IP telephone terminal 4 can also form an incoming call history of a call that has been placed on the own device, and can store and store this.

  Then, when making a call to the intended destination, in the mobile phone terminal 5, the transmission history of the e-mail information transmitted to the destination, the call history of the call made to the destination, the destination A communication history is formed by combining the incoming call history of incoming calls. The communication history formed in this way is displayed on the display 524 of the mobile phone terminal 5 so that it can be viewed before making a call. As a result, it is possible to make a telephone call while confirming what kind of communication has been performed so far with the other party to be called. In addition, based on the communication history displayed on the mobile phone terminal 5, it is possible to make a call to the intended destination.

  FIG. 11 is a sequence diagram for explaining display of communication history information and transmission processing. Although omitted in FIG. 11, in this example as well, processing similar to the processing in step S1A, step S2A, step S1B, and step S2B shown on the upper end side in FIG. 7 is performed. As a result, the IP phone terminal 4A and the mobile phone terminal 5A are connected by the USB cable 10, and the IP phone terminal 4B and the mobile phone terminal 5B are connected by the USB cable 10 in the respective devices. To be done.

  In this example, it is assumed that the control unit 540 of the mobile phone terminal 5A receives a communication history display instruction from the user through the operation input unit 521 (step S51). The process of step S51 is a process of accepting an item selection instruction (communication history display instruction) corresponding to the display of the communication history from a menu displayed on the display 524 in response to a predetermined operation.

  When receiving the communication history display instruction, the control unit 540 of the mobile phone terminal 5A connects to the Internet through the transmission / reception signal processing unit 503, the telephone communication unit 502, and the transmission / reception antenna 501, and accesses the Web service server 8. Then, the control unit 540 of the mobile phone terminal 5A forms a request for providing the storage history information of the e-mail information to the intended destination, and transmits this request to the Web service server 8 (step S52). In response to the provision request, the Web service server 8 forms an accumulation history of e-mail information for the instructed counterpart, and provides this to the requesting mobile phone terminal 5A (step S53). In this case, the accumulation history of e-mail information is information including a destination (e-mail address, name), transmission date and time, subject, URL indicating the storage location of the e-mail information, and the like.

  Next, the control unit 540 of the mobile phone terminal 5A forms a request for providing a call origination history and an incoming call history with respect to the target partner to the IP phone terminal 4A connected through the external terminal 531. Then, the data is transmitted to the IP telephone terminal 4A through the external I / F 532 and the external terminal 531 (step S54). In response to the provision request, IP telephone terminal 4A extracts the outgoing call history and incoming call history with the instructed counterpart, and provides them to requesting mobile phone terminal 5A (step S55). In this case, the outgoing call history and incoming call history are information including the destination (phone number, name), outgoing date / time or incoming date / time, outgoing / incoming call, subject, and the like.

  The control unit 540 of the mobile phone terminal 5A forms a communication history for the intended destination from the storage history of the e-mail information, the outgoing call history, and the incoming call history provided as described above. It is displayed (step S56). FIG. 12 is a diagram for explaining an example of communication history information in which an e-mail storage history, a call outgoing history, and an incoming call history are combined.

  The control unit 540 of the mobile phone terminal 5A combines the storage history of the provided email, the outgoing call history, and the incoming call history, and rearranges them using the date and time (send date / time, outgoing date / time, incoming date / time) as a key. This is displayed on the display screen 524 of the display 524 through the display controller 523. As a result, as shown in FIG. 12, communication history information in which a call origination / incoming history and an e-mail transmission history are combined can be displayed. When there is a lot of data of the communication history information, the display can be scrolled on the mobile phone terminal 5, and the whole can be displayed so that the user can see it.

  The history information shown in FIG. 12 is communication history information with “First Sales Department Tanaka”. In this case, at 10:54 on March 31, 2011 (Thursday), it was shown that the “Subject” was called out as “Subject for next fiscal year” and “Meeting for company A”. Yes. Note that the notification of the subject is performed by writing in the DisplayName of the INVITE message. In addition, before that, it is shown that an e-mail with “subject” as “subject of next term” is transmitted at 14:28 on Wednesday, March 30, 2011.

  In addition, at 11:01 on March 22, 2011 (Tuesday), an incoming call was received in which “Subject” was notified as “Correspondence to Company A”, and at 10:00 on Tuesday, March 22, 2011. It is shown that a telephone call notified with “subject” as “subject to A company” was received in 45 minutes, but it could not be answered due to absence. If the incoming call is not answered, as shown in FIG. 12, the control unit 430 of the IP telephone terminal 4 grasps it as “incoming (absent)”, and this is managed as information indicating whether the incoming / outgoing call is received. The Furthermore, in the case of the history information shown in FIG. 12, a telephone which notified “Subject” as “Regarding the matter corresponding to Company A on March 22” at 9:30 on Monday, March 21, 2011. It is shown that an e-mail with “Subject” as “About meeting schedule for company A” is transmitted at 17:15 on Thursday, March 17, 2011.

  Then, the user of the IP phone terminal 4A forms the history information shown in FIG. 12 and displays it on the display 524 of the mobile phone terminal 5, for example, before making a call to “First Sales Department Tanaka”. As a result, it is possible to grasp the status of telephone and e-mail communication exchanges with the former “First Sales Department Tanaka”, and to communicate appropriately without causing misunderstandings. Will be able to.

  12 is displayed on the display 524 of the mobile phone terminal 5A, and a call operation such as lifting the handset 440 of the IP phone terminal 4A is performed in a state where the cursor is positioned on the target display item. To do. In this case, the same processing as the processing of step S7 to step S11 described with reference to FIG. 7 is performed, and it is possible to automatically make a call to the destination of the history information. To be done.

  In the case of this example, in step S9, the information notified from the mobile phone terminal 5A to the IP phone terminal 4A includes the telephone number, subject, date and time (transmission date and time, transmission date and time) of the displayed communication history information. , Incoming date and time). Further, when the item on the communication history where the cursor is positioned is the transmission history of electronic mail information, a URL indicating the storage location (location) of the electronic mail information is also notified.

  In the outgoing call processing in step S11, when a URL is notified from the mobile phone terminal 5A, the URL is recorded in a predetermined area such as user information of the INVITE message. The subject name and date / time are recorded in the DisplayName of the INVITE message. In this way, it is possible to make a call to the other party of the communication based on the history information about the communication performed with the other party of the displayed target communication. . In this case, the location of the display information such as e-mail information corresponding to the item where the cursor is positioned on the displayed communication history can be notified to the telephone partner.

  In this way, it is possible to form history information relating to communications performed with the intended partner, and to display and confirm this. In addition, based on the history information, it is possible to make a call with a simple operation such as an off-hook operation without entering or selecting a telephone number to the other party of the history information, and to record the history of e-mail information. When the transmission is made based on the URL, the URL indicating the storage location can be notified. In addition, since the DisplayName of the INVITE message contains information indicating the subject and date / time (sent date / time, outgoing date / time, incoming date / time), displaying this information on the incoming side causes some requirements before answering the incoming call. Because you can know, you can expect a quick response.

[Modification]
In the above-described embodiment, the mobile phone terminal 5 connected to the IP phone terminal 4 refers to the information in the phone book memory 510 and acquires the telephone number of the other party to call.
