Therefore, in the following description, the dock devices 4 (1), 4 (2),...

  In the telephone system of this embodiment, as described above, the mobile phone terminal 5 can be connected to the SIP server 1 through the LAN 2 by connecting the mobile phone terminal 5 to the dock device 4, and the mobile phone terminal 5 The battery can be charged. Here, “connected to the SIP server 1” means that data can be transmitted to and received from the SIP server 1.

  In this way, when the mobile phone terminal 5 is connected to the SIP server 1 via the dock device 4, if the mobile phone terminal 5 receives an incoming call through the mobile phone network, the mobile phone terminal 5 forms incoming information. Then, this is transmitted to the dock device 4. The incoming call information includes caller information acquired (extracted) from the phone book data stored and held in the phone book database of the mobile phone terminal 5.

  The dock device 4 includes caller information included in incoming information from the mobile phone terminal 5, forms an INVITE (call) message compliant with SIP (Session Initiation Protocol), and provides this to the SIP server 1 via the LAN 2. . The sender information is inserted into the display name (Display name) of the INVITE message. When the SIP server 1 receives the INVITE message from the dock device 4, the SIP server 1 provides the subordinate IP phone terminals 3 (1), 3 (2),. Notify that there is.

  Accordingly, the incoming call from the mobile phone network to the mobile phone terminal 5 can be notified to the IP phone terminals 3 (1), 3 (2),... Under the SIP server 1. In this case, since the source information from the mobile phone terminal 5 is included in the display name in the INVITE message from the SIP server 1, the call is sent to each of the IP phone terminals 3 (1), 3 (2),. Notification (display) of the original telephone number and name can be performed.

  Then, it is assumed that the user performs a response operation for the incoming call notification to any of the IP telephone terminals 3 (1), 3 (2),. In this case, information indicating that a response operation has been performed from the IP telephone terminal 3 on which the response operation has been performed is notified to the SIP server 1, the dock device 4, and the mobile phone terminal 5.

A call can be made with 3. That is, using the mobile phone terminal 5 as one gateway device in the telephone system of this embodiment, a mobile phone is connected between the call originator for the mobile phone terminal 5 and the IP phone terminal 3 under the SIP server 1. A communication path through the network is connected so that a call can be made between the caller and the IP telephone terminal 3.

  Since the caller information is provided from the mobile phone terminal 5, even if there is no telephone directory data corresponding to the IP phone terminal 3, the caller information such as the caller's telephone number or name is used as the caller information. It can be displayed on the display of the terminal 3. In other words, the phone book data registered in the mobile phone terminal 5 can be used also in the IP phone terminals under the SIP server 1 within a limited range of notification of the caller at the time of incoming call. .

  As described above, the telephone system according to this embodiment uses the mobile phone terminal 5 as a gateway device, and uses the phone book data stored in the mobile phone terminal 5 to the IP phone under the SIP server 1 as much as necessary. The terminal 3 can also be used. Hereafter, each apparatus which comprises the telephone system of this embodiment is demonstrated concretely.

[Configuration Example of SIP Server 1]
Next, the configuration of the SIP server 1 of the telephone system of this embodiment will be described. FIG. 2 is a block diagram for explaining a configuration example of the SIP server 1. As shown in FIG. 2, the SIP server 1 includes a connection terminal 101 to the IP network 6, an IP network interface (hereinafter abbreviated as IP network I / F) 102, and a packet decomposition / generation unit 103. ing. The SIP server 1 includes a telephone network interface (hereinafter abbreviated as a telephone network I / F) 104, a connection terminal 105 to the telephone network 7, and an address management database (hereinafter abbreviated as an 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. 2, 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 decomposition / generation unit 103 performs packet decomposition and generation. Specifically, a packet to be transmitted from the IP telephone terminal 3 or the like connected to the SIP server 1 through the LAN 2 to the terminal device connected to the telephone network 7 is transmitted to the control unit 110 through the connection terminal 108 and the LAN I / F 107. Will be accepted. The packet is supplied from the control unit 110 to the packet decomposing / generating unit 103, where the packet is decomposed, and then transmitted to the telephone network through the telephone network I / F 104 and the connection terminal 105, and transmitted to the intended destination. To be done.

  Further, data from the terminal device connected to the telephone network to the subordinate IP telephone terminal 3 connected to the SIP server 1 through the LAN 2 is received by 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 3 is transmitted.

  Packets are transmitted and received between the terminal connected to the IP network 6 and the IP telephone terminal 3 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 the data format and transmit / receive it as it is. Similarly, packets are also transmitted and received between devices such as the IP telephone terminal 3 and the dock device 4 connected to the SIP server 1 via the LAN 2, so that the packet decomposition / generation unit 103 performs packet decomposition and generation. The packet is transmitted and received through the LAN I / F 107.

  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 3 or the like connected to the own device through the LAN 2 is surely specified. 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 3 or the like connected to the own device through the LAN 2.

  FIG. 3 is a diagram for describing a configuration example of management information (database) formed in the address management DB 106. The address management DB 106 of the SIP server 1 has address information about the IP telephone terminal 3 connected to the SIP server 1 through the LAN in addition to the address information of the terminal apparatus of the other IP telephone system connected to the IP network 6. It can be managed.

  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 3 connected to the SIP server 1 via 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 3 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 3 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 3 based on the management information of its own address management DB 106, and the identified IP telephone terminal 3 , Perform message forwarding.

  When an IP telephone number is used for making a call, although not shown in FIG. 1, a gateway or DNS (Domain Name System) connected to the IP network 6 is used to start from the IP telephone number. A URI or the like is retrieved and used. Similarly, when making a call using the IP telephone number to the IP telephone terminal 3 constituting the telephone system of this embodiment from the other party, the gateway or DNS connected to the IP network 6 is used. Thus, the URI or the like 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. It is something that can be done. Therefore, the main device 1 according to this embodiment is capable of performing connection between the external line and the internal line, connection between the internal lines, and notifying the subordinate IP telephone terminal 3 of the use status of the communication line. .

  Further, as described with reference to FIG. 1, the cellular phone terminal 5 can be connected to the SIP server 1 through the LAN 2 and the dock device 4. As will be described later, it is assumed that the SIP server 1 receives an INVITE message indicating that the mobile phone terminal 5 has an incoming call through the dock device 4 connected through the LAN I / F 107 and the connection terminal 108. In this case, the control unit 110 of the SIP server 1 sends an INVITE message including the source information from the dock device 4 to the LAN 2 through the LAN I / F 107 and the connection terminal 108 and provides it to the subordinate IP telephone terminal 3. .

  Then, it is assumed that the SIP server 1 receives a response from the subordinate IP telephone terminal 3 to the INVITE message after sending the INVITE message through the LAN I / F 107 and the connection terminal 108. In this case, the control unit 110 of the SIP server 1 forms a response instruction, transmits the response instruction to the LAN 2 through the LAN I / F 107 and the connection terminal 108, and transmits the response instruction to the mobile phone terminal 5 that has received the incoming call through the dock device 4. Like that.

  Then, after sending the response instruction, the control unit 110 of the SIP server 1 relays the voice data between the subordinate IP telephone terminal that has made the response and the mobile telephone terminal 5 that is receiving the incoming call. . As described above, the control unit 110 of the SIP server 1 realizes functions as a call control unit, a response instruction control unit, and a call control unit, and receives an incoming call to the mobile phone terminal 5 connected to the own device through the dock device 4. On the other hand, a function of responding through the subordinate IP phone terminal 3 and making a call through the IP phone terminal 3 is also realized.

  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. Further, the control unit 110 forms control information for controlling lighting and extinguishing of LEDs and the like to be supplied to each IP telephone terminal 3 connected through the LAN 2 in accordance with 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 is transmitted to each IP telephone terminal 3 and the like.

  In FIG. 2, the packet decomposing / generating unit 103 is shown as an independent circuit part, but 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.

[Configuration example of IP phone terminal]
Next, the configuration of the IP telephone terminal 3 used in the telephone system of this embodiment will be described. FIG. 4 is a block diagram for explaining a configuration example of the IP telephone terminal 3 of the telephone system of this embodiment.

  As shown in FIG. 4, the IP telephone terminal 3 according to this embodiment mainly includes a LAN connection terminal 301, a LAN I / F 302, a packet processing unit 303, a call voice input / output interface (hereinafter, referred to as a telephone function). Call voice input / output I / F.) 304, handset connection terminal 305, handset 306, operation input unit 311, operation input interface (hereinafter referred to as operation input I / F) 312, display controller 313, display 314, ringer 315 It has.

  Further, the IP telephone terminal 3 of this embodiment includes a control unit 320 that controls each unit. The control unit 320 is a microcomputer configured by connecting a CPU 321, a ROM 322, and a RAM 323 through a CPU bus 324. Here, the CPU 321 reads out and executes a program stored in the ROM 322, generates a control signal to be supplied to each part and supplies it to each part, or processes data supplied from each part. To do. As described above, the ROM 322 stores and holds various programs executed by the CPU 321 and various data necessary for processing. The RAM 323 is mainly used as a work area, such as temporarily storing intermediate results of processing.

[Action when incoming]
The packet data transmitted via the LAN 2 is supplied to the LAN I / F 302 through the LAN connection terminal 301, converted into data in a format that can be processed by the own machine, and then transmitted via the CPU bus 324. It is supplied to the packet processing unit 303. The packet processing unit 303 decomposes and extracts control data and audio data included in the supplied packet data. The control data extracted here is supplied to the control unit 320 and used for controlling the own device. If voice data addressed to the own device (own terminal) is included, the voice data is supplied to the call voice input / output I / F 304 through the CPU bus 324.

  When the control data decomposed and extracted by the packet processing unit 303 is a call message to the own device, the control unit 320 controls the ringer 315 to ring the incoming call. At the same time, the control unit 320 controls the display controller 313 to display a message for notifying that there is an incoming call, a telephone number or name of the caller, or an extension number of the caller on the display screen of the display 314.

  When the user lifts the handset 306 from the main body of the IP telephone terminal 3 in response to an incoming call to the own device, the IP telephone terminal 3 enters an off-hook state. In this case, the control unit 320 forms a message responding to the incoming call, packetizes it in the packet processing unit 303, and supplies it to the LAN I / F 302. The LAN I / F 302 converts the packet data into packet data for transmission, sends it to the LAN 2 through the LAN connection terminal 301, and transmits it to the call destination terminal.

  As a result, a communication path is generated between the caller and a call is started. In this case, the packet including the voice data from the other party is supplied to the packet processing unit 303 through the LAN connection terminal 301 and the LAN I / F 302 as described above. The packet processing unit 303 disassembles a packet from the other party, and supplies control data to the control unit 320 and audio data to the communication audio input / output I / F 304.

[Telephone system operation]
Next, when the mobile phone terminal 5 is connected to the SIP server 1 through the dock device 4, the mobile phone terminal 5 receives an incoming call through the mobile phone network (3G line). The operation of the telephone system of the embodiment will be specifically described. FIG. 7 is a sequence diagram for explaining the operation of the telephone system of this embodiment.

  As shown at the bottom in FIG. 7, the mobile phone terminal 5 is connected to a mobile phone network (described as a 3G line in FIG. 7). Then, as described above, the mobile phone terminal 5 and the dock device 4 are connected by the USB cable through the USB terminal. The SIP server 1, the IP telephone terminals 3 (1), 3 (2),... And the dock devices 4 (1), 4 (2),. Connected through the LAN cable.

  Then, in FIG. 7, it is assumed that an incoming call occurs to the mobile phone terminal 5 through the mobile phone network (3G line) as shown in the upper right end portion. In this case, the mobile phone terminal 5 accepts the incoming call and notifies the incoming call information to the dock device 4 connected through the external terminal 531. That is, as described above, the mobile phone terminal 5 acquires the caller information including the caller's phone number and name from the phone book DB 514 based on the caller's phone number included in the incoming call notification. The incoming call information including the caller information is formed and provided to the dock device 4.

  When the dock device 4 receives incoming information from the mobile phone terminal 5 connected to its own device, the dock device 4 recognizes that an incoming event has occurred. In this case, as described above, the dock device 4 forms an INVITE (call) message in which the caller information included in the received call information from the mobile phone terminal 5 is inserted into the display name, and this is transmitted through the LAN 2 to the SIP server. 1 to send.

  When the SIP server 1 receives the INVITE message from the dock device 4, the SIP server 1 transmits it to the subordinate IP telephone terminals 3 (1), 3 (2),. In this case, each of the subordinate IP telephone terminals 3 (1), 3 (2),... Executes a calling process that emits a ringing tone in response to the INVITE message, and sends a ringing (180 RINGING) message to the SIP server. Reply to 1 When the SIP server 1 receives the in-call message from the subordinate IP phone terminals 3 (1), 3 (2),..., The SIP server 1 sends it to the dock device 4 to which the mobile phone terminal 5 that has received the incoming call is connected. To send.

  As a result, the dock device 4 makes a call for an incoming call to the mobile phone terminal 5 connected to the own device at the IP phone terminals 3 (1), 3 (2),. I can grasp that. In this case, the dock device 4 transmits a current telephone state display instruction indicating that a call is being made to the mobile phone terminal 5 connected to the own device. In the mobile phone terminal 5 that has received the telephone status display instruction, the telephone status display is updated, such as starting ringing.

  Thereafter, in this example, as shown in FIG. 7, it is assumed that the IP telephone terminal 3 (1) performs a response operation for an incoming call generated at the mobile telephone terminal 5. In this case, IP telephone terminal 3 (1) stops ringing and transmits a message (200 OK) indicating that it has responded to the INVITE message to SIP server 1. As a result, the SIP server 1 can grasp that the response operation has been performed in the subordinate IP telephone terminal 3 (1).

  The SIP server 1 first transmits a response to the incoming call from the IP telephone terminal 3 (1) to the dock device 4 to which the mobile telephone terminal 5 that has received the incoming call is connected. Further, the SIP server 1 transmits a cancel (CANCEL) message for stopping the calling to the IP telephone terminals 3 (2), etc. other than the IP telephone terminal 3 (1) that has transmitted the incoming call response. To do. As a result, the IP telephone terminal 3 (2),..., Etc. that received the cancellation message stop emitting the ringtone and send a response (200 OK) to the cancellation message to the SIP server 1.

  On the other hand, the dock device 4 grasps that the response to the incoming call to the mobile phone terminal 5 connected to the own device has been made in the IP phone terminal 3 (1) by the above notification from the SIP server 1. Can do. In this case, the dock device 4 gives a current telephone state display instruction indicating that there is an incoming call response to the mobile phone terminal 5 connected to the own device. In response to this, in the cellular phone terminal 5 that has received the telephone status display instruction, processing such as stopping ringing of a ringing tone, starting a preparation operation for starting a call, and starting display of a call time. I do.

  Next, the dock device 4 gives a response instruction to the mobile phone terminal 5 connected to the own device. Thereby, the said mobile telephone terminal 5 performs a response process, forms an incoming call response, and transmits to a transmission origin, and connects a communication path between the said transmission origin. As a result, a communication path is connected between the IP telephone terminal 3 (1) that has made a response to the incoming call and the caller. In this case, a communication path is connected between the IP telephone terminal 3 (1) and the caller via the SIP server 1, the dock device 4, and the mobile telephone terminal 5, as shown in FIG.

  Thus, in the telephone system of this embodiment, when there is an incoming call through the mobile phone network to the mobile phone terminal 5 connected to the SIP server 1 through the dock device 4, the IP under the control of the SIP server 1. A response can be made through the telephone terminal 3 to make a call. Even if the IP phone terminal 3 does not have the caller's phonebook data, the phonebook data in the phonebook DB 514 of the caller's mobile phone terminal 5 can be used. In other words, the IP telephone terminal 3 under the SIP server 1 can use the telephone directory data held by the mobile telephone terminal 5 only when an incoming call is received.

[Processing of mobile phone terminal 5]
Next, processing performed in the mobile phone terminal 5 used in the telephone system of this embodiment will be described. FIG. 8 is a flowchart for explaining processing performed in the mobile phone terminal 5 of this embodiment. The process shown in FIG. 8 is a process mainly executed in the control unit 540 in the cellular phone terminal 5 that is turned on.

  The control unit 540 of the mobile phone terminal 5 monitors whether or not there is an incoming call based on a signal from a neighboring base station received by the transmitting / receiving antenna 501 and the telephone communication unit 502 at every predetermined timing. (Step S101). If it is determined in step S101 that there is no incoming call, the control unit 540 determines whether or not an operation for making a call through the operation input unit 521 and the operation input I / F 522 has been received (step S101). Step S102).

  When it is determined in the determination process in step S102 that an operation for making a call is not accepted, the control unit 540 repeats the process from step S101. If it is determined in step S102 that an operation for making a call has been accepted, a call process for making a call by making a call to the destination is executed (step S103). . Then, when the call ends and the on-hook state is established, the control unit 540 ends the series of calling processing in step S103 and repeats the processing from step S101.

  Further, when it is determined in the determination process of step S101 that there is an incoming call to the own device, the control unit 540 determines whether or not it is connected to the dock device 4 through the external terminal 531 (step S104). As described above, when connected to the dock device 4 through the external terminal 531, the control unit 540 exchanges signals with the dock device 4 through the external terminal 531 and the external I / F 532. Therefore, the control unit 540 can appropriately grasp whether or not the own device is connected to the dock device 4.

  When it is determined in the determination process in step S104 that it is not connected to the dock device 4 through the external terminal 531, a normal incoming call process is performed so that a call can be made with the caller (step S105). . Specifically, the processing in step S105 is performed when the user performs an off-hook operation by emitting a ringtone, vibrating a vibrator, or displaying the name of the caller on the display 524. Connect the communication path through the network and make a call. Then, when the call ends and the on-hook state is made, the control unit 540 ends the series of incoming processing in step S105 and repeats the processing from step S101.

  Further, when it is determined in step S104 that the terminal is connected to the dock device 4 through the external terminal 531, the control unit 540 generates incoming information and notifies the dock device 4 through the external terminal 531. The process of (transmission) is performed (step S106). That is, in step S106, first, the control unit 540 controls the transmission source information acquisition unit 511, and based on the telephone number of the transmission source included in the incoming call notification, necessary information such as the name of the transmission source from the telephone directory DB 514. Is extracted to form sender information consisting of a phone number and name. Further, in step S106, the control unit 540 controls the incoming call information generation unit 512 to form incoming call information including the caller information acquired by the caller information acquisition unit 511, which is used as the external I / F 532 and the external terminal. Notification is made to the dock device 4 through 531.

  Thereafter, the control unit 540 determines whether or not the instruction information from the dock device 4 is received through the external terminal 531 and the external I / F 532 (step S107). If it is determined in the determination process in step S107 that the instruction information has not been received, it is determined whether or not the incoming call addressed to the own device through the mobile phone network continues (step S108). If it is determined in the determination process in step S108 that the incoming call addressed to the own device continues, the process from step S107 is repeated. Also, in the determination process of step S108, when it is determined that the incoming call to the own device is not continued (finished) due to the on-hook of the transmission source, for example, the dock device 4 is notified that the incoming call has ended. A predetermined end process is executed (step S109), and the process from step S101 is repeated.

  Further, in the determination process of step S107, when it is determined that there is instruction information from the dock device 4 (received), the control unit 540 determines whether or not the instruction information is a response instruction (step S110). When it is determined in the determination process in step S110 that the instruction is not a response instruction, the control unit 540 executes a process according to the instruction (step S111) and repeats the process from step S107. That is, in step S111, when the instruction from the dock device 4 is, for example, the above-described telephone state display instruction, the ringtone is emitted or stopped or the call is started according to the instruction. For example, a process for performing the process is performed.

  In the determination process of step S110, when it is determined that the instruction information from the dock device is a response instruction, the control unit 540 executes the response process (step S112). Specifically, in step S112, the control unit 540 first forms an incoming response, transmits this to the transmission source through the transmission / reception signal processing unit 503, the telephone communication unit 502, and the transmission / reception antenna 501, connects the communication path, Make calls. Thereafter, the control unit 540 controls the relay processing unit 513 to place the own device in a call state (step S113).

  When the communication state is established, the voice data from the caller received through the telephone communication unit 502 and the transmission / reception signal processing unit 503 is supplied to the relay processing unit 513 and converted into voice data in a format to be transmitted to the dock device 4 here. Is done. The converted voice data from the transmission source is transmitted to the dock device 4 through the external I / F 532 and the external terminal 531, and transmitted to the IP telephone terminal 3 (1) as the response source through the dock device 4 and the SIP server 1. To be. Also, the voice data from the IP telephone terminal 3 (1) received through the external terminal 531 and the external I / F 532 is supplied to the relay processing unit 513, where the voice data is transmitted to the source via the mobile phone network. Converted. The converted voice data from the IP telephone terminal 3 (1) is sent to the mobile phone network through the transmission / reception signal processing unit 503 and the telephone communication unit 502, and transmitted to the caller.

  Thereafter, control unit 540 determines whether or not the call between the caller and IP telephone terminal 3 (1) has been terminated (step S114). Repeat the process. Further, in the determination process of step S114, since either the IP telephone terminal 3 (1) or the caller has performed an on-hook operation or the like, when determining that the call has ended, the control unit 540 releases the communication line or the like. The predetermined end process is performed (step S115), and the process from step S101 is repeated.

  As described above, when the mobile phone terminal 5 of this embodiment is not connected to the SIP server 1 through the dock device 4, it functions as a normal mobile phone terminal and transmits from its own device. To answer incoming calls. Then, when the cellular phone terminal 5 of this embodiment is connected to the SIP server 1 through the dock device 4, it functions as a so-called gateway device of the telephone system, and receives an incoming call to its own device. Handle as an incoming call to the telephone system.

[Processing of Dock Device 4]
Next, processing performed in the dock device 4 used in the telephone system of this embodiment will be described. FIG. 9 is a flowchart for explaining the processing performed in the dock device 4 of this embodiment, for explaining the processing performed when the mobile phone terminal 5 is connected through the external terminal 411. is there. The process shown in FIG. 9 is a process executed mainly in the control unit 430 of the dock device 4.

  When the mobile phone terminal 5 is connected to the own device through the external terminal 411, the control unit 430 has received the incoming information from the mobile phone terminal 5 through the external terminal 411 and the external I / F 412. Is monitored (step S201). When it is determined in the determination process in step S201 that incoming information from the mobile phone terminal 5 connected to the own device through the external terminal 411 has not been received, the process from step S201 is repeated.

  When it is determined in the determination process of step S201 that the incoming information from the mobile phone terminal 5 connected to the own device through the external terminal 411 has been received, the control unit 430 forms a call message and displays it as a SIP server. 1 is notified (transmitted) (step S202). That is, in step S202, the control unit 430 controls the call message generation unit 421 to form an INVITE message in which the source information of the incoming information from the mobile phone terminal 5 is inserted into the display name. Then, the control unit 430 sends the INVITE message to the LAN 2 through the LAN I / F 402 and the LAN connection terminal 401 and transmits it to the SIP server 1.

  Then, the control unit 430 determines whether or not the incoming call to the mobile phone terminal 5 connected to the own device continues (step S203). When it is determined in step S203 that the incoming call to the mobile phone terminal 5 has not been continued (the incoming call has ended), for example, a predetermined end process such as notifying the SIP server 1 that the incoming call has ended. Is executed (step S204). Thereafter, the control unit 430 repeats the processing from step S201.

  If it is determined in the determination process in step S203 that the incoming call to the mobile phone terminal 5 continues, the control unit 430 receives a notification from the SIP server 1 through the LAN connection terminal 401 and the LAN I / F 402. It is determined whether or not (step S205). If it is determined in step S205 that the notification from the SIP server 1 has not been received, the control unit 430 repeats the process from step S203.

  When it is determined in step S205 that the notification from the SIP server 1 has been received, the control unit 430 determines that the received notification is a response that a response operation has been performed on any IP telephone terminal 3. It is determined whether or not the notification is made (step S206). In the determination process of step S206, when it is determined that the notification from the SIP server is not a response notification, the control unit 430 executes a process according to the received notification from the SIP server 1 (step S207) and from step S203. Repeat the process. In step S207, as described with reference to FIG. 7, a process of notifying the calling and instructing to change the status display of the mobile phone terminal 5 is performed.

  When determining that the notification from the SIP server is a response notification in the determination process in step S206, the control unit 430 responds to the mobile phone terminal 5 via the external I / F 412 and the external terminal 411. Processing to be performed is executed (step S208). Specifically, as described with reference to FIG. 7, first, the mobile phone terminal 5 is notified that there is a response to the incoming call that has occurred to the mobile phone terminal 5, and the status display After that, a response instruction to the incoming call is transmitted to the mobile phone terminal 5 to connect the communication path.

  Thereafter, the control unit 430 controls the relay processing unit 422 to place the own device in a call state (step S209). In step S209, when the communication state is established, the voice data from the transmission source provided through the mobile phone terminal 5 received through the external terminal 411 and the external I / F 412 is supplied to the relay processing unit 513, where the SIP server 1 is converted into audio data in a format to be transmitted to the first. The converted voice data from the transmission source is transmitted to the SIP server 1 through the LAN I / F 402 and the LAN connection terminal 401, and transmitted to the IP telephone terminal 3 (1) as the response source through the dock device 4 and the SIP server 1. To be. Also, the voice data from the IP telephone terminal 3 (1) received through the LAN connection terminal 401 and the LAN I / F 402 is supplied to the relay processing unit 513, where it is converted into voice data in a format to be transmitted to the mobile phone terminal 5. The The converted voice data from the IP phone terminal 3 (1) is supplied to the mobile phone terminal 5 through the external I / F 412 and the external terminal 411, and the responding IP phone terminal 3 through the dock device 4 and the mobile phone terminal 5. The voice data from (1) is transmitted to the sender.

  Thereafter, control unit 430 determines whether or not the call between the caller and IP telephone terminal 3 (1) has ended (step S210), and when it determines that the call has not ended, it determines in step S210. Repeat the process. Further, in the determination process in step S210, since either the IP telephone terminal 3 (1) or the caller has performed an on-hook operation or the like, when determining that the call has ended, the control unit 430 releases the communication line or the like. The predetermined end process is performed (step S211), and the process from step S201 is repeated.

  In this way, the dock device 1 connects the mobile phone terminal 5 to the SIP server 1, and the voice between the IP phone terminal 3 subordinate to the SIP server 1 and the call originator for the mobile phone terminal 5. Data relay processing is also performed. In addition to the data transmission / reception processing described above, the dock device 4 also has a function of supplying a charging current to the mobile phone terminal 5 connected to the own device and charging the battery of the mobile phone terminal 5. ing.

[Processing of SIP Server 1]
Note that, as described above, the SIP server 1 performs address resolution between terminals connected to a communication path (communication line). For this reason, in the case where the mobile phone terminal 5 is connected to the SIP server 1 through the dock device 4, also in the SIP server 1, the dock device 4 transmitted and received through the LAN 2 and the subordinate IP phone terminal 3 Address resolution is performed even during the period of time, and a process for connecting the communication path and enabling communication is performed.

  That is, the control unit 110 of the SIP server 1 also accepts information from the dock device 3 through the LAN 2. Then, it is assumed that the control unit 110 of the SIP server 1 receives an INVITE message indicating that there is an incoming call from the dock device 4 to the mobile phone terminal 5 connected to the dock device 4 through the LAN 2. In this case, the control unit 110 of the SIP server 1 sends the INVITE message including the source information from the mobile phone terminal 5 to the LAN 2 through the LAN I / F 107 and the connection terminal 108 and provides it to the subordinate IP phone terminal 3. To do.

  Then, after sending the INVITE message, the control unit 110 of the SIP server 1 accepts a response from the subordinate IP telephone terminal 3 to the INVITE message through the LAN I / F 107 and the connection terminal 108. Then, it is assumed that the control unit 110 of the SIP server 1 receives a response to the INVITE message from the subordinate IP telephone terminal 3. In this case, the control unit 110 of the SIP server 1 forms a response instruction, sends it to the LAN 2 through the LAN I / F 107 and the connection terminal 108, and transmits it to the mobile phone terminal 5 that has received the incoming call through the dock device 4. To.

  Furthermore, after sending the response instruction, the control unit 110 of the SIP server 1 relays voice data between the subordinate IP telephone terminal that has made the response and the mobile telephone terminal 5 that has received the incoming call. To. As described above, the control unit 110 of the SIP server 1 executes the steps of call control, response instruction control, and call control, and in response to an incoming call to the mobile phone terminal 5 connected to the own device through the dock device 4. A response is made through the subordinate IP phone terminal 3 so that a call can be made through the IP phone terminal 3.

[Effect of the embodiment]
Thus, in the telephone system of this embodiment, the mobile phone terminal 5 can be connected to the SIP server 1 only by connecting the mobile phone terminal 5 to the dock device 4. Then, the mobile phone terminal 5 is used as one of so-called gateway devices of the telephone system, and responds to the incoming call to the mobile phone terminal 5 through the IP phone terminal 1 under the control of the SIP server 1 and between the caller. A communication line can be connected to make a call. The phone book data registered in the phone book DB 514 of the mobile phone terminal 5 can be used in the IP phone terminal 3 under the SIP server 1 only when the mobile phone terminal 5 receives an incoming call. . Accordingly, it is possible to prevent the inconvenience that the phone book data in the phone book DB 514 of the mobile phone terminal 5 is used without limitation by a third party, and privacy is infringed.

[Other examples of notification of sender information]
In the above-described embodiment, when the mobile phone terminal 5 is connected to the SIP server 1 through the dock device 4 and the mobile phone terminal 5 receives an incoming call through the mobile phone network, the mobile phone terminal 5 5, the incoming call information including the caller information is provided to the dock device 4. The sender information is generated based on the phone book data stored and held in the phone book DB 514 of the mobile phone terminal 5 as described above. Therefore, the telephone directory data of the mobile phone terminal 5 can be used in the IP phone terminal 3 under the SIP server 1 only when an incoming call is made to the mobile phone terminal 5 through the mobile phone network.

  However, privacy protection may not be enough. Therefore, another example of the notification of the sender information described below is to protect the privacy more appropriately by using the phone book data stored in the phone book DB 514 of the mobile phone terminal 5 more finely, It is intended to improve usability.

  10 and 11 are diagrams for explaining another example of notification of source information. In the example described below, the phone book data held in the phone book DB 514 of the mobile phone terminal 5 is registered with, for example, company phone book data, private phone book data, and individual incoming phone calls. It can be registered separately from the book data. Then, when an incoming call occurs in the mobile phone terminal 5 through the mobile phone network, the phone book DB 514 is referred to based on the caller telephone number included in the incoming call notification, and the caller telephone number is selected from which type. It is discriminated whether it is registered as telephone directory data, and the contents of notification are made different according to the discrimination result.

  Specifically, as shown in the upper, middle, and lower stages in FIG. 10, the notification process of the caller information is made different depending on the type of the phonebook data of the caller. In other words, it is assumed that an incoming call has occurred in the mobile phone terminal 5 and the caller's telephone number has been registered as corporate telephone directory data. In this case, as shown in the upper part of FIG. 10, caller information including a telephone number and a name registered in the company telephone directory data is generated, and this is included in the incoming call information so that the dock device 4 To provide. This is because corporate telephone directory data is information necessary for business, and privacy problems do not arise. As in the case of the above-described embodiment, the dock device 4 forms an INVITE message including the source information as a display name and transmits it to the SIP server 1 so that the IP telephone terminal 3 under the SIP server 1 The sender information is used as display information.

  Further, it is assumed that the mobile phone terminal 5 receives an incoming call and the caller's telephone number is registered as private telephone directory data. In this case, as shown in the middle of FIG. 10, the caller information not including the caller information is generated without generating the caller information including the telephone number and name registered in the private phonebook data. Forming and providing it to the docking device 4. This is because private telephone directory data causes privacy problems. The dock device 4 forms an INVITE message that does not include source information and transmits it to the SIP server 1. Thereby, the IP telephone terminal 3 under the SIP server 1 can be notified of the incoming call, but the sender can be notified.

  When an incoming call occurs and the telephone number of the caller is registered as private telephone directory data, the occurrence of the incoming call itself can be prevented from being notified to the dock device 4. That is, it is possible to make it impossible to respond to an incoming call from a destination registered as private telephone directory data through the IP telephone terminal 3 under the SIP server 1.

  Further, it is assumed that the mobile phone terminal 5 receives an incoming call and the caller's phone number is registered as individual incoming phone book data. In this case, as shown in the lower part of FIG. 10, the telephone number and name registered in the individual incoming phone book data are included, and the caller is the destination of the individual incoming call target. The source information including the information to be shown is generated, and this is included in the incoming information and provided to the dock device 4.

  Here, the individual incoming call means, for example, an incoming call from a destination that is notified of a call from a specific destination by changing the ring tone from a normal ring tone. In this case, the dock device 4 forms an INVITE message including the caller information including the caller's telephone number, name, and information indicating that the caller is the destination of the individual incoming call, and transmits the message to the SIP server 1. To do. Thereby, in the IP telephone terminal 3 under the control of the IP server 1, the caller information can be used as display information, and for example, it is possible to control the ring tone to be different from the normal ring tone. .

  In addition, information indicating which IP telephone terminal 3 under the SIP server 1 receives the incoming call telephone directory data held in the telephone directory DB 514 of the mobile telephone terminal 5, for example, the extension of the IP telephone terminal 3 Register a number. Then, the sender information including information for specifying the IP telephone terminal 3 is notified to the SIP server 1 through the dock device 4. As a result, the SIP server 1 can grasp which IP telephone terminal 3 is to receive the call, so that the SIP server 1 receives the incoming call to the cellular phone terminal 5 only to the instructed IP telephone terminal 3. It can also be notified.

  As described above, at least two management methods can be used as the phone book data management method for properly using the phone book data, as shown in FIGS. In the management system shown in FIG. 11A, for example, a telephone directory data file 514A, a private telephone directory data file 514B, and an individual incoming telephone directory data file 514C are provided in the telephone directory DB 514. Then, the company phone book data, private phone book data, and individual incoming phone book data are registered and managed in corresponding files. Then, when receiving an incoming call to the mobile phone terminal 5, the transmission source information acquisition unit 511 refers to the registration data of each of the files 514A, 514B, and 514C described above based on the telephone number of the transmission source. As a result, the sender information acquisition unit 511 can determine which type of the phone book data of the sender is based on which file the phone book data of the sender is registered in. Is done.

  In the management system shown in FIG. 11B, the phone book data is centrally managed in the phone book DB 514. However, for each phone book data consisting of other information such as a phone number, name, address and e-mail address, etc. Thus, a classification (flag) indicating the type of the telephone directory data is attached. In the case of the example shown in FIG. 11B, the classification information (1) for the company phone book data, “2” for the private phone book data, and “3” for the individual incoming phone book data ( An example in the case of adding flag information) is shown. As a result, when receiving an incoming call to the mobile phone terminal 5, the caller information acquisition unit 511 refers to the registration data in the phonebook DB 514 based on the caller's telephone number, and classifies (flags) the corresponding phonebook data. Based on the above, it is possible to determine what kind of telephone directory data of the transmission source.

  If the incoming call to the mobile phone terminal 5 is from a private source registered as private phone book data, the source information is not displayed on the IP phone terminal 3, but in other cases In some cases, it is desired to display the sender information. As a simple control method in this case, there is a method in which specific information or a specific flag for not displaying the transmission source information is added to the transmission source information and transmitted from the mobile phone terminal 5 to the dock device 4. .

  FIGS. 12 and 13 are diagrams for explaining a method of controlling the display / non-display of the transmission source information by adding specific information or a specific flag to the transmission source information. As shown in FIG. 12, it is assumed that the mobile phone terminal 5 connected to the SIP server 1 by being connected to the dock device 4 receives an incoming call through the mobile phone network. And since the transmission origin information which the transmission origin information acquisition part 511 of the mobile telephone terminal 5 acquired was private telephone book data, the control part 540 of the mobile telephone terminal 5 determined not to notify transmission origin information. To do.

  In this case, the incoming information generation unit 512 of the mobile phone terminal 5 displays, for example, specific information that means non-notification of incoming caller information such as “184” or a specific flag that means non-notification of incoming caller information. The incoming call information is added to the caller information and includes the caller information. This incoming information is provided to the dock device 4.

  In the dock device 4, first, as shown in the flowchart of FIG. 13, first, specific information or a flag indicating non-notification of the incoming call source information is included in the outgoing call source information included in the incoming call information from the mobile phone terminal 5. It is determined whether or not it has been added (step S202A). If it is determined in step S202A that it has been added, only the incoming call notification is made to the SIP server 1, and the sender information is not notified (step S202B). If it is determined in step S202A that it has not been added, an INVITE message including source information is formed and provided to the SIP server 1 (step S202C).

  By doing so, it is possible to prevent the mobile telephone terminal 5 from using the telephone number or name of the caller managed as private telephone directory data in the IP telephone terminal 3 subordinate to the SIP server 1. Note that the processing in steps S202A to S202C shown in FIG. 13 is performed in place of the processing in step S202 shown in FIG.

  Then, all the source information included in the incoming information, including the information indicating non-notification and the source information to which the flag is added, is stored and held as one of the incoming history information in the dock device 4. To do. Thereby, when necessary, the user of the mobile phone terminal 5 knows where the incoming call is received from the mobile phone terminal 5 by referring to the sender information stored and held in the dock device 4. You can also

  Here, the dock device 4 determines whether or not to notify the SIP server 1 of the caller information, but is not limited thereto. Information indicating display / non-display or source information with a flag is also provided to the SIP server 1, and the SIP server 1 determines whether to provide the source information to the subordinate IP phone terminal 3. May be.
