Description

  The present invention relates to an apparatus and a program used for making a telephone call to a destination of a created or received electronic mail.

  2. Description of the Related Art Conventionally, in a telephone communication system, a caller number notification service provided by a telephone company can display a caller's telephone number on a display (display unit) of a receiving telephone terminal. As a result, the receiving side can first answer the call by confirming the other party by the telephone number notified before answering. However, the caller number notification service is a service for notifying the callee of the telephone number on the caller side, and cannot display a message for display such as a message message even if it is short.

  Therefore, the display message is transmitted using electronic mail. However, in the case of an e-mail, an e-mail viewing software (mailer) is activated at the transmission destination, and an e-mail addressed to himself / herself is acquired from his / her mailbox and viewed, so that the e-mail cannot be viewed. For this reason, the caller can transmit the display message easily and in a short time, and the reception side can confirm the display message even before performing a response operation or when the response cannot be made. It is desirable.

  In order to solve this problem, in Patent Document 1 described later, a message input by a caller or a message prepared by an exchange (base station) is added to an INFOMATION message defined in a connection sequence related to outgoing / incoming calls. An invention for inserting and transmitting is disclosed. This allows the caller to send the message easily and in a short time, and the incoming message such as the mobile communication terminal extracts and displays the message, and even if the message cannot be answered, the message message is confirmed. To be able to.

  However, in the case of the invention disclosed in Patent Document 1, it is necessary to newly provide a function for extracting a display message from the INFOMATION message and displaying it on the receiving side. Specifically, the receiving side receives (1) an information message when it arrives, (2) extracts a display message from the source from the received information message, and (3) an extracted display message. Appears on the display. Such a function needs to be newly provided. This is explained using FIG. 10 in paragraph [0064] of Patent Document 1, for example.

  For this reason, even if it is possible to send a display message from the caller to the callee without making any change to the communication device such as a telephone terminal on the receiver, It is desirable to be able to confirm the display message. Such a request is one of the important issues when realizing cooperation between electronic mail and telephone.

  For example, as described above, when an electronic mail is transmitted, it is generally unknown whether the other party has seen the electronic mail. For this reason, in the case of important communication, it is also a business manner to make telephone contact for confirmation as well as e-mail. Then, in the case of telephone contact for an e-mail that has been transmitted in advance, it is convenient if the telephone terminal on the receiving side can display what the telephone call is for. Since the receiving side can know before the response what the incoming call to the device is for, a quick response can be expected.

  In view of the above, the present invention transmits message information from the caller to the callee and makes a response operation on the callee without making any significant changes to at least the communication device on the callee. The purpose is to enable confirmation of message information from the sender even before the message is sent.

In order to solve the above-described problem, a telephone communication terminal according to the first aspect of the present invention provides:

The display device
A display device side connection end that enables connection to the base device;
An outgoing notification accepting means for accepting a notification that an outgoing operation has been performed from the base device;
When the display device is connected to the base device through the display device side connection end and the display information is displayed on the display device by the display control device, a transmission operation is performed from the base device through the transmission notification receiving device. A notification means for providing the base device with the predetermined information included in the display information when a notification is received,
The base device is
A base device side connection end that enables connection of the display device;
When the display device is connected through the base device side connection end, and a transmission operation is received through the reception unit, a notification that the transmission operation has been performed is formed and provided to the display device An outgoing notification providing means,
Provided information receiving means for receiving the predetermined information from the display device;
With
The transmission processing unit forms an invite message including the predetermined information from the display device received through the provision information receiving unit in a display name (DisplayName) and transmits the message .

  According to the telephone communication terminal of the first aspect of the invention, various display information is displayed on the display means by the display control means. When a display operation is received through the reception unit when the display information is displayed on the display unit, the transmission processing unit converts the predetermined information included in the display information into an INVITE message that is a transmission message. Is included in the display name (DisplayName).

  The information recorded in the display name is originally displayed as “source display name” at the destination. For this reason, predetermined information included in the display information displayed on the display means of the caller is transmitted from the caller to the callee without any change to the communication device (phone terminal) on the callee. This can be displayed on the display means of the communication device on the receiving side.

  According to the present invention, message information corresponding to display information can be transmitted from a caller to a callee only with a very simple operation. On the receiving side, the message information from the sender is received without making a major change to the communication device, and the message information from the sender is displayed even before the response operation is performed. Can be confirmed.

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 to the IP network 6. The IP network I / F 102 receives a packet supplied through the IP network 6, 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 6.

  The connection terminal 105 constitutes a connection end to the telephone network 7. The telephone network I / F 104 receives data supplied through the telephone network 7, converts the data into data in a format that can be processed by the own device, 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 7.

  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 decomposing / generating unit 103 is a unit that decomposes and generates packets, and mainly performs a call between a terminal device connected to the telephone network 7 and the IP telephone terminal 4 under the SIP server 1. In addition, the data packets to be transmitted and received are decomposed and generated. Specifically, a packet to be transmitted from the IP telephone terminal 4 or the like connected to the SIP server 1 through the LAN 2 to the terminal device connected to the telephone network 7 is supplied to the control unit 110 through the connection terminal 108 and the LAN I / F 107.

  Packets are transmitted and received between the terminal connected to the IP network 6 and the IP telephone terminal 4 connected to the SIP server 1 through 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 6 or the LAN 2 in order to realize a registrar server function, and stores and holds address information about a terminal device 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.

  Basically, the management information formed in the address management DB 106 of the SIP server 1 is a URI (SIP URI) transmitted from a terminal device connected to the IP network 6 and an IP address as described above. 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 receives a call 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 6. 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 accepts an incoming call request (outside line incoming call) to the IP telephone terminal 4 connected to the LAN 2 through the IP network 6 or the telephone network 7. 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.

  Further, 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 6 is used to start from an IP telephone number. A URI or the like is 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, the gateway or DNS connected to the IP network 6 is used. Then, the URI is retrieved from the IP telephone 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.

Then, it is assumed that the mobile phone terminal 5 has received an instruction input for displaying target electronic mail information through the operation input unit 521 and the operation input I / F 522. In this case, in the mobile phone terminal 5, the control unit 540 and the display controller 523 function to display an e-mail and enable browsing of target e-mail information (step S4). In these steps S3 and S4, the mobile phone terminal 5 and the IP phone terminal 4 do not communicate.

  Thereafter, an operation (off-hook operation) in which the handset 440 of the IP telephone terminal 4 is picked up from the main body of the IP telephone terminal 4 in order to make a call to the other party of the e-mail displayed on the display screen of the display 524 of the mobile phone terminal 5. ) Is performed (step S5). The operation in step S5 may be a transmission operation for pressing an off-hook key (transmission button) or the like.

  The off-hook operation is detected by the on-hook / off-hook detection unit 406 and notified to the control unit 430. In this case, the control unit 430 of the IP telephone terminal 4 requests provision of a telephone number or the like of the other party related to the electronic mail information displayed on the display 524 of the mobile phone terminal 5. (Step S6). The processing in step S6 is a request for providing information related to the displayed electronic mail information, and corresponds to a request for browsing mail information.

  In the cellular phone terminal 5 that has received the request for the browsing email information, the email information notification processing unit 511 functions under the control of the control unit 540 to acquire information to be provided to the IP phone terminal 4, and this acquisition The information is provided to the IP telephone terminal 4 (step S7). In step S7, the mail information notification processing unit 511 obtains the telephone number of the other party who makes the call specified according to the displayed e-mail information and the predetermined information extracted from the displayed e-mail information. Provided to IP telephone terminal 4.

  As described above, the e-mail information displayed on the display 524 of the mobile phone terminal 5 is transmitted from the mobile phone terminal 5, and the e-mail address of the transmission source is the user's mobile phone terminal 5. Is. Therefore, when the e-mail information displayed on the display screen of the display 524 of the mobile phone terminal 5 is as shown in FIG. 8A, the e-mail information notification processing unit 511 is the e-mail address of the user of the own device. The e-mail address of “First Sales Department Tanaka”, which is a different destination, is extracted as the e-mail address of the other party who makes the call.

  Then, the mail information notification processing unit 511 refers to the data in the phone book memory 510 of the own device based on the extracted email address of “First Sales Department Tanaka”, and the “First Sales Department Tanaka” Get a phone number. Further, the mail information notification processing unit 511 holds information stored as “subject” and “date and time (transmission date and time)” from predetermined information included in the displayed e-mail information. To extract information. Then, the mail information notification processing unit 511 provides the IP telephone terminal 4 with information indicating the acquired telephone number, “subject name”, and “date and time (transmission date and time)”.

  As described above, (1) extraction of the e-mail address of the other party making the call, (2) identification of the telephone number of the other party making the call based on the extracted e-mail address, and (3) information included in the e-mail information In step S7, the process of extracting predetermined information to be transmitted, (4) providing the specified telephone number, and extracting the predetermined information to the IP telephone terminal 4 is performed. The information provided from the mobile phone terminal 5 to the IP phone terminal 4 is information specified or extracted according to the displayed e-mail information. It is browsing mail information to.

  Thereafter, the IP telephone terminal 4 that has received provision of information such as a telephone number from the mobile telephone terminal 5 temporarily stores the received telephone number and other information in the RAM 433 and analyzes the information (browsing mail information). (Analysis) is performed (step S8). In this browsing mail information analysis process, when it is confirmed that information such as a telephone number has been properly received, a response (200 OK) is transmitted to the mobile phone terminal 5. In addition, when information such as a telephone number is not provided from the mobile phone terminal 5, a request for retransmission of information such as a telephone number is requested, and a necessary information such as a telephone number is retransmitted from the mobile phone terminal 5. Can be.

  The IP telephone terminal 4 that has received provision of the predetermined information included in the telephone number or e-mail information from the mobile telephone terminal 5 makes a call to the other party of the telephone number and also indicates that the call is in progress Notification to the terminal 5 is performed (step S9). In this step S 9, in the IP telephone terminal 4, first, the outgoing call processing unit 421 functions under the control of the control unit 430, and the outgoing message (INVITE) to the destination of the telephone number provided from the mobile phone terminal 5. Message). In this case, the outgoing call processing unit 421 records the information indicating “subject name” and “date and time (transmission date and time)” provided from the mobile phone terminal 5 in DisplayName, in addition to including the telephone number of the caller in the INVITE message. To do.

  The INVITE message formed in the transmission processing unit 421 is transmitted to the SIP server 1 through the control unit 430, the LAN I / F 402, and the LAN connection terminal 401. Then, the SIP server 1 specifies the destination to make a call in response to the INVITE message from the IP telephone terminal 4, and transmits the INVITE message to the destination to make the call (step S10).

  Thus, from the IP telephone terminal 4, the “title” and “date / time (transmission date / time)” of the e-mail information displayed on the mobile phone terminal 5 are displayed in the DisplayName in the INVITE message for the intended destination. It is described and transmitted. The destination of the INVITE message (the other party making the call) performs an incoming call notification process or the like according to the INVITE message addressed to its own device, but displays the Display Name information of the INVITE message on its own display. The process to do is also performed.

  In other words, the other party who made the call automatically extracts the “subject” and “date and time (transmission date and time)” from the DisplayName of the INVITE message addressed to the own device, and automatically performs a process of displaying this on the display of the own device. As described above, since the information described in DisplayName of the INVITE message is information to be displayed, the information is processed so as to be automatically displayed on the telephone terminal on the receiving side.

  As a result, as shown in FIG. 8B, the display of the telephone terminal on the receiving side in this case displays “Incoming” indicating that the incoming call is received and “050XXXXZZZZ” as the caller's telephone number as usual. Done. Further, as shown in FIG. 8B, the display of the information of the information recorded as “Subject” in the DisplayName and “Date / time (transmission date / time)” are displayed on the display of the telephone terminal on the receiving side. Information display “@ 2011.3.31” is performed. In FIG. 8B, the number “5000” at the upper right end is an extension number of the IP telephone terminal 4.

  Then, the user of the telephone terminal on the receiving side looks at the display of his / her telephone terminal that receives the incoming call, so that the telephone that is currently on the telephone terminal is transmitted on “March 31, 2011”. In addition, it is possible to recognize that the subject is a telephone contact regarding “the target of the next term”. For this reason, it can be expected that the destination user recognizes the display content and quickly answers the call. In addition, the user on the receiving side has the merit of being able to answer the call by preparing for correspondence by being able to know what the telephone call is for before answering.

  As described above, in addition to the calling process, in step S9, under the control of the control unit 430, the terminal display control unit 422 also forms a call information notification and provides it to the mobile phone terminal 5. Done. The outgoing information notification notifies the mobile phone terminal 5 that it is currently making a call and indicates that the call is being made.

  In the mobile phone terminal 5 that has received the transmission information notification from the IP phone terminal 4, the display information processing unit 512 controls the display controller 523 through the control unit 540 to display the display screen on the display 524 as a calling display ( Step S11). In the case of this example, for example, a display of “first sales department Tanaka” in the destination column, which is a display of the other party who made the call, is displayed blinking as a display during outgoing.

  Then, when the incoming call destination “First Sales Department Tanaka” performs an operation (off-hook operation) for responding to an incoming call to his / her own telephone terminal, the incoming call response is sent from the telephone terminal to the SIP server 1. (Step S12). The incoming call response is notified to the caller IP telephone terminal 4 through the SIP server 1 (step S13). As a result, the communication path is connected between the IP telephone terminal 4 that is the call originator and the telephone terminal of “First Sales Department Tanaka” that is the call recipient via the SIP server 1 so that a call can be made. (Step S14).

  When the communication path is thus connected and a call is made, the terminal display control unit 422 of the IP telephone terminal 4 forms a call information notification under the control of the control unit 430, and this is transmitted to the mobile phone. This is provided to the terminal 5 (step S15). The call information notification notifies the mobile phone terminal 5 that a call is currently being made and notifies the mobile phone terminal 5 that the call is being made.

  In the mobile phone terminal 5 that has received the call information notification from the IP phone terminal 4, the display information processing unit 512 controls the display controller 523 through the control unit 540 so that the display on the display 524 is displayed during a call ( Step S16). In the case of this example, the display information processing unit 512 functions, and for example, the display of the destination called “first sales department Tanaka”, which is the display of the other party who made the call, is displayed in enlarged bold characters. . Further, the portion may be made more conspicuous, for example, highlighted or displayed in reverse.

  Thereafter, it is assumed that the call is terminated and the user of the IP telephone terminal 4 performs an on-hook operation to return the handset 440 to the main body of the IP telephone terminal 4 (step S17). In this case, the control unit 430 of the IP telephone terminal 4 first forms a disconnect request and transmits it to the SIP server 1 through the LAN I / F 402 and the LAN connection terminal 401 (step S18). In response to the disconnection request from the IP telephone terminal 4, the SIP server 1 disconnects the communication path connected to the IP telephone terminal 4 (step S19).

  Thereafter, the terminal display control unit 422 forms an end-call information notification and provides it to the mobile phone terminal 5 (step S20). The end-of-call information notification is to notify that the communication path is disconnected and to return to the normal display.

  In the mobile phone terminal 5 that has received the end-of-call information notification from the IP phone terminal 4, the display information processing unit 512 controls the display controller 523 through the control unit 540 and returns the display on the display 524 to the normal display ( Step S21). Here, the normal display means a normal display of the e-mail information as shown in FIG. 8A. Thereby, even when the display of the e-mail information of the mobile phone terminal 5 returns to the normal display (FIG. 8A), the user can recognize that the call has ended.

  If the other party who made the call first performs an on-hook operation, the IP telephone terminal 4 is notified that the other party has gone on-hook, for example, a busy tone is supplied. For this reason, when the user of the IP phone terminal 4 also performs an on-hook operation, the communication path is also released on the IP phone terminal 4 side, and the display of the mobile phone terminal 5 is also normally displayed by performing the processing of step S20 and step S21. Can be returned to.

  In this way, the user simply performs an extremely intuitive and simple call operation such as an off-hook operation while displaying and checking e-mail information on the display 524 of the mobile phone terminal 5 connected to the IP phone terminal 4. A call can be made to the other party of the e-mail information. In addition, the “subject name” and “date and time (transmission date and time)” included in the e-mail information to be displayed can be transmitted in the DisplayName of the INVITE message.

  Then, the receiving-side telephone terminal displays the DisplayName information included in the INVITE message addressed to itself as usual. In other words, it is not necessary for the receiving telephone terminal to make any changes in order to display the transmitted display message. As a result, the user on the receiving side can know the requirement that the telephone terminal is receiving a call before performing a response operation. Therefore, in the case of an important business, it is possible to respond promptly and to respond to incoming calls in a better state, such as preparing for feelings before responding.

[Use communication history]
By the way, in the telephone system shown in FIG. 1, an IPV terminal connected to the LAN 2 can send and receive an INVITE message in which predetermined information such as “subject” is described in the DisplayName. Also, between different telephone systems configured as shown in FIG. 1 and connected to the IP network 6, an INVITE message in which predetermined information such as “subject” is described in the DisplayName can be transmitted and received.

  In this way, in the telephone system that can send and receive the similarly formed INVITE message, every time a call is made, the destination of the call, the date and time of the call, A history with “subject” as information can be formed and held. Also, with respect to transmitted e-mail information, a history with the date and time of occurrence of the transmission and the subject as information can be formed and held.

  For this reason, in the telephone system of this embodiment, for each telephone or e-mail destination, history information is formed by combining the call origination / incoming history and the e-mail transmission history, and a call is made while watching this. It can be used when calling. FIG. 9 is a diagram for explaining an example of communication history information in which a call outgoing / incoming history and an e-mail transmission history are combined.

  In this embodiment, the incoming / outgoing telephone call history is formed in, for example, the EEPROM 434 of the IP telephone terminal 4. In this case, the destination can be identified by the destination or the telephone number of the sender included in the transmitted INVAIT message. That is, in the case of outgoing from the own device, the destination can be specified by the telephone number of the destination included in the transmitted INVITE message. In the case of incoming to the own device, the sender of the received INVITE message The other party can be specified by phone number.

  Further, the date and time of occurrence of incoming / outgoing calls can be obtained from the clock circuit provided in the IP telephone terminal 4 although not shown in FIG. Further, the distinction between outgoing / incoming calls can be grasped according to the operation state of the own device determined by the control unit 430 each time an incoming / outgoing call occurs. Further, the “subject” can be acquired by extracting the information on the DislayName of the INVAIT message that has been transmitted or received. Such information is extracted by the control unit 430 of the IP telephone terminal 4 and stored in, for example, the EEPROM 434 as outgoing / incoming call history information for each destination that can be distinguished by the telephone number.

  Further, in this embodiment, the transmission history of the electronic mail is stored in the EEPROM 544 of the mobile phone terminal 5 because the mobile phone terminal 5 transmits and receives the electronic mail. In the case of this example, it can be formed by extracting the transmission date / time and subject of the electronic mail transmitted from the own device and storing it for each destination (transmission destination). Note that the mobile phone terminal 5 may store e-mail information transmitted from the own device, thereby forming an e-mail transmission history as necessary.

  Then, the IP phone terminal 4 and the mobile phone terminal 5 are connected by the USB cable 8, and the outgoing / incoming history of the intended destination phone and the transmission history of the e-mail are combined with the mobile phone terminal 5. Assume that a predetermined operation for displaying communication history information is performed. The predetermined operation in this case is, for example, an operation of selecting an item for displaying the communication history information from a menu and then selecting a target destination from, for example, destinations registered in the phone book data Etc.

  When the predetermined operation is performed, the control unit 540 of the mobile phone terminal 5 forms a request for providing a call origination / reception history for the intended destination, and transmits the request to the IP through the external I / F 532 and the external terminal 531. It transmits to the telephone terminal 4. In response to this, the control unit 430 of the IP telephone terminal 4 extracts a call origination / incoming history of the destination phone from the EEPROM 434 and provides it to the mobile phone terminal 5 through the external I / F 412 and the external terminal 411.

  The control unit 540 of the mobile phone terminal 5 combines the call origination / incoming history from the IP phone terminal 4 and the e-mail transmission history held by the own device, and rearranges them using the date and time as a key, It is displayed on the display screen of the display 524 through 523. As a result, as shown in FIG. 9, it is possible to display history information obtained by combining the incoming / outgoing call history and the e-mail transmission history. 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. 9 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. 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. 9, 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. 9, a telephone which notified “Subject” as “A Case for 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 4 forms the history information shown in FIG. 9 and displays it on the display 524 of the mobile phone terminal 5 before calling “First Sales Department Tanaka”, for example. 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.

  9 is displayed on the display 524 of the mobile phone terminal 5 and a call operation such as lifting the handset 440 of the IP phone terminal 4 is performed in a state where the cursor is positioned on the target display item. To do. In this case, the mobile phone terminal 5 uses the telephone number of the “first sales department Tanaka” who is the other party of the history information, the information recorded as the “subject” of the selected item, The transmission date and time is provided to the IP telephone terminal 4.

  Then, as described above, the IP telephone terminal 4 forms an INVITE message for the other party of the telephone number provided from the mobile telephone terminal 5, but makes a call by describing information such as the subject name provided in the DisplayName. . As a result, even when history information is displayed on the display screen of the mobile phone terminal 5, in the same way as when the above-described e-mail information is displayed, the destination of the call is specified, and “subject” It is possible to make a call to a desired destination by notifying necessary information such as.

  Here, in order to simplify the description, the e-mail has been described as forming a transmission history of the e-mail transmitted from the mobile phone terminal 5, but the present invention is not limited to this. It is of course possible to include a history of electronic mail received by the mobile phone terminal 5 and form an electronic mail outgoing / incoming history. In the case of an e-mail incoming history, the destination can be specified by the e-mail address of the sender, and the date and time can be grasped by acquiring the date and time when the own machine received the e-mail from the own clock circuit. be able to. Further, the predetermined information such as “subject” can be acquired from the received e-mail information.
