  Next, the identifier registration operation of the IP telephone terminal according to the embodiment of the present invention will be described. First, at the start of use of the IP telephone terminal 1, an identifier is set for the IP telephone terminal device to be used. That is, when the user instructs the start of identifier setting using the input unit 15, the control unit 12 reads an identifier registered in advance from the identifier storage unit 14 and displays the read identifier on the display unit 16.

  Here, as identifiers to be registered in the identifier storage unit 14, for example, assuming a limited use scene such as an extension telephone in the home, “first floor”, “second floor”, “living room”, etc. Examples of identifier candidates that can identify the IP telephone terminal device to be used, such as a place of use and a user such as “grandfather”, “mother”, and “eldest son”, can be mentioned.

  FIG. 2 is a diagram illustrating a display example when an identifier is selected. As shown in FIG. 2, registered identifier candidates are listed and displayed. The user uses the input unit 15 to select and determine an identifier to be set from the identifiers displayed on the display unit 16, thereby setting the identifier in the IP telephone terminal device 1 to be used.

  As described above, when the IP telephone terminal device 1 starts to be used, it is not necessary to input an identifier character, and it is only necessary to select from the candidates. Therefore, the identifier can be registered easily and easily.

  Next, the operation of the IP telephone system of the present invention will be described. FIG. 3 is a schematic configuration diagram showing an IP telephone system according to the embodiment of the present invention. As shown in FIG. 3, in the IP telephone system according to the embodiment of the present invention, IP telephone terminal devices 1 a to 1 d are connected via a communication line 2 so as to communicate with each other. IP telephone terminal apparatuses 1a to 1d have the same configuration as IP telephone terminal apparatus 1 described in FIG.

  FIG. 4 is a sequence diagram for explaining a call origination operation of the IP telephone system according to the embodiment of the present invention. In the present embodiment, “living room” is set as the identifier of IP telephone terminal apparatus 1b, “eldest son” is set as the identifier of IP telephone terminal apparatus 1c, and “mother” is set as the identifier of IP telephone terminal apparatus 1b. Will be described.

  In the IP telephone terminal device 1a, when the user uses the input unit 15 to give an instruction for starting a call or searching for another device, the control unit 12 transmits another device, that is, an IP phone terminal, via the communication unit 11 and the communication line 2. A search message is multicast or broadcasted to the devices 1b, 1c, and 1d (step S1).

  When receiving the search message from the IP telephone terminal apparatus 1a, the control unit 12 of the IP telephone terminal apparatuses 1b, 1c, and 1d receives the IP address assigned to the own terminal and the set identifier (respectively, “living room”, A response message including “eldest son” and “mother”) is transmitted to the IP telephone terminal device 1a (steps S2, S3, and S4).

  When the IP telephone terminal device 1a receives the response message from the IP telephone terminal devices 1b, 1c, and 1d, the identifier-address management unit 13 creates an identifier-IP address correspondence table as management information. FIG. 5 is a diagram illustrating an example of an identifier-IP address correspondence table. As shown in FIG. 5, in the identifier-IP address correspondence table, the identifier and IP address of each IP telephone terminal device transmitted in steps S2, S3, and S4 are associated.

  Then, the control unit 12 causes the display unit 16 to display the IP telephone terminal device as an identifier of the transmission destination as an identifier. FIG. 6 is a diagram illustrating a display example when a call destination is selected. As shown in FIG. 6, identifiers are listed and displayed as transmission destination candidates. The user can use the input unit 15 to select and determine a call destination from the identifier displayed on the display unit 16. Therefore, the user can make a call operation only by selecting a desired call destination without being aware of the IP address or directly inputting the identifier.

  Next, when the user determines “eldest son” as the call destination (step S6), the control unit 12 refers to the identifier-IP address correspondence table and sets “192.168.2.11” as the call destination IP address. "Is set. Then, a connection request is made to the set IP address, that is, to the IP telephone terminal device 1c (step S7). If IP telephone terminal apparatus 1c can communicate, a response indicating that communication is possible is transmitted (step S8), and a call between IP telephone terminal apparatus 1a and IP telephone terminal apparatus 1c is started (step S9). ).

  According to such an IP telephone terminal device of the embodiment of the present invention, it is only necessary to select an identifier candidate as a communication destination at the time of outgoing call of the IP telephone terminal device. It can be performed.

  In addition, since a communication destination can be directly specified by an IP address without using a SIP URI, an IP telephone system that can be used in an environment in which no SIP server is installed can be provided.

  Furthermore, even in an environment where IP address changes and user changes for each terminal frequently occur, it is not necessary to update the address book for each terminal device one by one. The identifier of the IP telephone terminal device can be obtained.

  The IP telephone terminal device and the communication method thereof according to the present invention have an effect of selecting a communication destination candidate without requiring troublesome operations such as character input, and are useful for an in-house extension telephone system and the like.
