  This telephone system includes a SIP server 10 as an exchange and a plurality of relay dual mobile phones 30A, 30B, 30C belonging to a system connected to the SIP server 10 by a wireless LAN. One or more IP telephones (IP-TEL) 20A, 20B, 20C, 20D, and 20E are connected to the SIP server 10. Hereinafter, the relay dual mobile phones 30A to 30C are referred to as relay terminals 30A to 30C.

  In this telephone system, when the telephone number of the destination telephone on the cellular phone network is input from the IP telephones 20A to 20E, the SIP server 10 selects and activates any one of the relay terminals 30A to 30C. The telephone numbers input from the IP telephones 20A to 20E are transmitted to the relay terminals 30A to 30C. Then, the selected relay terminals 30A to 30C call the given telephone number. When the other party's telephone responds to the call, the originating IP telephones 20A to 20E can communicate with the other party's telephone using the selected relay terminals 30A to 30C as relays.

In this telephone system, the telephone number for the mobile phone communication network assigned to each of the relay terminals 30A to 30C is a telephone number for calling the IP telephones 20A to 20E from outside the system.
When the telephone numbers of the relay terminals 30A to 30C are called from a telephone outside the system via the mobile phone communication network, the relay terminals 30A to 30C having the telephone numbers are received. Then, the fact that there is an incoming call is transmitted to the SIP server 10, and the SIP server 10 selects and calls the IP telephones 20A to 20E corresponding to the incoming relay terminals 30A to 30C.

FIG. 2 is a block diagram showing the SIP server 10 in FIG.
The SIP server 10 manages the IP telephones 20A to 20E as subordinates, and performs call control of these IP telephones 20A to 20E. The SIP server 10 includes a CPU 11, a memory 12 that is connected to the CPU 11 and stores a data table, an audio processing circuit 13 that converts an audio signal, an access point 14 that is wirelessly connected to the relay terminals 30A to 30C, An antenna 15 and a LAN connector 16 are provided. The access point 14 is wirelessly connected to the relay terminals 30 </ b> A to 30 </ b> C via the antenna 15. The CPU 11 and the voice processing circuit 13 are connected to the IP telephones 20A to 20E via the LAN connector 16.

  Data table selects LAN telephone numbers of managed relay terminals 30A-30C and subordinate IP telephones 20A-20E, information of IP telephones 20A-20E corresponding to each of relay terminals 30A-30C, and relay terminals 30A-30C Then, information regarding the rank when used as a relay device, information on telephones within a range communicable with the SIP server 10 among the relay terminals 30A to 30C, and the like are stored.

FIG. 3 is a configuration diagram showing an outline of the relay terminals 30A to 30C in FIG.
Each of the relay terminals 30A to 30C includes a mobile phone communication unit 31 as a mobile phone communication unit using a mobile phone communication network (not shown), and a WLAN communication function unit 32 as an access point communication unit using a LAN of the IP phone communication network. And a control unit 33 for controlling the mobile phone communication unit 31 and the WLAN communication function unit 32, an antenna 34 connected to the mobile phone communication unit 31 and the WLAN communication function unit 32, an operation button (not shown), and the like. .

  Each of the relay terminals 30A to 30C is provided with a telephone number for a cellular phone network and a telephone number for a LAN, and the WLAN communication function unit 32 operates in the LAN area. The mobile phone communication unit 31 operates outside the LAN area and operates as a mobile phone that is controlled by a telephone number for the mobile phone network.

  Each of the relay terminals 30A to 30C includes a normal operation mode in which the mobile phone communication unit 31 or the WLAN communication function unit 32 operates, and a relay mode in which both the mobile phone communication unit 31 and the WLAN communication function unit 32 can operate in conjunction with each other. Have

Each of the relay terminals 30A to 30C belonging to the system stores an identifier (ID) given to the access point 14 provided in the SIP server 10. Relay terminals 30 </ b> A to 30 </ b> C receive signals transmitted at regular intervals from access points existing in the vicinity by WLAN communication function unit 32, and extract the IDs of the access points included in the signals. When the extracted ID matches the stored ID, the relay terminals 30A to 30C are switched from the normal operation mode to the relay mode.
When the relay mode is set, the relay terminals 30A to 30C serve as relay machines.

  When the relay terminals 30A to 30C are attached to the charger, the mode may be switched to the relay mode. In this case, if the charger is arranged within a range where the SIP server 10 can be connected to the wireless LAN, the relay terminals 30A to 30C are set to the relay mode by attaching the relay terminals 30A to 30C to the charger. Can do.

Moreover, you may make it the structure which switches a relay mode and a normal operation mode with the switch provided in relay terminal 30A-30C.
For example, the SIP server 10 transmits a control signal to the relay terminals 30A to 30C for which the relay mode is selected, and activates the mobile phone to call a predetermined telephone number.

Next, the operation of the telephone system shown in FIG. 1 will be described.
Since the relay terminals 30 </ b> A to 30 </ b> C can each be carried, the relay terminals 30 </ b> A to 30 </ b> C can be taken out of the office where the SIP server 10 is installed.
At this time, if the relay terminals 30A to 30C reach outside the communicable range of the access point 14, the WLAN communication function unit 32 of the relay terminals 30A to 30C cannot identify the ID assigned to the access point 14, The mode switches to normal operation mode.

  When the relay terminals 30A to 30C are placed in a predetermined place in the company, that is, where the access point 14 of the SIP server 10 and the WLAN communication function unit 32 of the relay terminals 30A to 30C are capable of wireless LAN communication, the relay terminals 30A to 30A 30C becomes the relay mode.

  The SIP server 10 records in the data table while updating information of terminals within the communicable range via the access point 14 among the relay terminals 30A to 30C belonging to the system. For example, when the relay terminal 30A enters the range in which the relay terminal 30A can communicate with the SIP server 10 via the access point 14, the SIP server 10 records information indicating that the relay terminal 30A is in the communicable range in the data table, and relays it. When the terminal 30A is out of the communicable range, the information indicating that the relay terminal 30A is within the communicable range is deleted.

  Here, it is assumed that all of the relay terminals 30A to 30C are in the relay mode, and a case where a call is first made from the IP telephone side will be described.

  For example, when the telephone number of the destination telephone is dialed from the IP telephone 20A, the SIP server 10 selects, for example, the relay terminal 30A from the relay terminals 30A to 30C and transmits information. The selection of the relay terminal 30 </ b> A is performed by the CPU 11 based on the data table recorded in the memory 12.

The information transmitted from the SIP server 10 to the relay terminal 30A includes the identifier of the relay terminal and the telephone number information of the connection destination input from the IP telephone 20A.
When the telephone number of the connection destination input from the IP telephone 20A is the telephone number of a telephone outside the system, the information transmitted from the SIP server 10 to the relay terminal 30A further includes a call control request signal to the mobile telephone network. Etc. are included.

  When a call control request signal and telephone number information are transmitted from the SIP server 10 to the mobile phone network, the relay terminal 30A receives the telephone number information at the WLAN communication function unit 32, and the telephone number information is sent to the relay terminal 30A itself. When pointing, the relay terminal 30A is ringed. As a result, the relay terminal 30A and the IP telephone 20A can communicate with each other via the access point 14.

  When the received telephone number information indicates a telephone outside the system, relay terminal 30A starts relay communication by receiving a call control request signal. In this case, the relay terminal 30A activates the mobile phone communication unit 31 by the control signal from the SIP server 10 and transmits the call control request signal and the telephone number information to the mobile phone network via the antenna 34 and the base station. Call the other party's phone. When the other party's telephone responds, IP telephone 20A can talk to the other party's telephone via relay terminal 30A and access point 14 of SIP server 10.

  During this call, a signal from the other party's telephone is received by the mobile phone communication unit 31 of the relay terminal 30A and transmitted from the WLAN communication function unit 32 to the SIP server 10, and the SIP server 10 converts the received signal to the IP telephone 20A. To send. Conversely, a signal from the IP telephone 20A is transmitted to the SIP server 10, and the SIP server 10 transmits the received signal to the relay terminal 30A via the access point 14. The relay terminal 30A receives the signal transmitted from the SIP server 10 by the WLAN communication function unit 32, and transmits the signal from the mobile phone communication unit 31 to the destination telephone via the mobile phone network.

  The relay terminal 30A is in the relay mode, and receives information from the mobile phone network by the mobile phone communication unit 31, and the WLAN communication function unit 32 transmits the information to the access point 14, and the information from the access point 14 is received. Is received by the WLAN communication function unit 32 and the information is transmitted to the mobile phone network by the mobile phone communication unit 31, it is determined that the relay communication is being performed, and the operation button is pressed until the relay communication ends. Disable the operation. By doing so, even if the operation button is accidentally pressed during the relay communication, the relay communication is not hindered.

Next, an operation when a call is received from a telephone outside the system via a mobile phone network to a relay terminal will be described.
For example, when the relay terminal 30A receives a call from a telephone outside the system, the mobile phone communication unit 31 of the relay terminal 30A receives a call signal and a call control request signal for the relay terminal 30A.

  When the mobile phone communication unit 31 receives the call control request signal and the call signal, the relay terminal 30A rings and starts relay communication. The WLAN communication function unit 32 receives the call signal, and the WLAN communication function unit 32 receives the call signal. The SIP server 10 is notified of an incoming call via the access point 14. In response to this, the CPU 11 of the SIP server 10 selects and calls the IP telephone 20A, for example, based on the data table stored in the memory 12. When IP telephone 20A responds, IP telephone 20A and a telephone outside the originating system can communicate with each other via relay terminal 30A and access point 14 of SIP server 10. It is also possible to respond at the relay terminal 30A. When the response is made at the relay terminal 30A, the relay communication is completed, and the relay terminal 30A and a telephone outside the originating system can talk. When the relay terminal 30A responds, the relay terminal 30A notifies the SIP server 10 that the response has been made, and the SIP server 10 stops calling the IP telephone 20A.

  During a call between the telephone outside the originating system and the IP telephone 20A, a signal from the telephone outside the originating system is received by the mobile phone communication unit 31 of the relay terminal 30A, and the access point 14 is transmitted from the WLAN communication function unit 32. The SIP server 10 sends the received signal to the IP telephone 20A. Conversely, a signal from the IP telephone 20A is transmitted to the SIP server 10, and the SIP server 10 transmits the received signal to the mobile phone communication unit 31 of the relay terminal 30A via the access point 14. The relay terminal 30A receives the signal transmitted from the SIP server 10 by the WLAN communication function unit 32 and transmits the signal from the mobile phone communication unit 31 to a telephone outside the system via the mobile phone network.

  As described above, even when a call is received from the telephone outside the system to the relay terminal 30A and the relay terminal 30A relays communication between the telephone outside the system and the IP telephone 20A under the control of the SIP server 10, the relay terminal 30A Is in the relay mode, the mobile phone communication unit 31 receives information from the mobile phone network, the WLAN communication function unit 32 transmits the information to the access point 14, and the information from the access point 14 is transmitted to the WLAN communication. If the function unit 32 receives the information and the mobile phone communication unit 31 is transmitting it to the mobile phone network, it is determined that the relay communication is being performed, and the operation of the operation button is disabled until the relay communication ends. To. By doing so, even if the operation button is accidentally pressed during the relay communication, the relay communication is not hindered.

  On the other hand, when a call from a telephone outside the system is answered using the relay terminal 30A, the telephone outside the system of the caller and the relay terminal 30A are connected by the mobile phone communication unit 31 of the relay terminal 30A. At this time, the operation of the operation button is not invalidated.

As described above, the telephone system of the present embodiment has the following advantages.
(1) Since the SIP server 10 serving as an exchange and the relay terminals 30A to 30C are connected by a wireless LAN, a connection device or connector is unnecessary and can be realized at low cost.
