  Embodiments of the present invention will be described with reference to the drawings. The following example is only one specific example of the present invention, and the present invention is not limited to the following embodiment.

  FIG. 1 is a diagram showing a configuration of a telephone system in the present embodiment. This telephone system includes a wireless IP telephone 63, a wireless LAN base station 64, and a call connection control device 11. The wireless IP telephone 63 and the wireless LAN base station 64 are connected by radio, and call connection with the wireless LAN base station 64 is established. The control device 11 is connected by a LAN 31. In this telephone system, a personal computer 51, a fixed IP telephone 62, a private branch exchange 21 for connecting to the public network 41, and a router 22 for connecting to the IP network 42 are connected to the LAN 31.

  FIG. 2 is a flowchart showing a procedure of a call connection control method implemented in the call connection control device 11. FIG. 3 shows the contents of processing 1, processing 2, and processing 3 in the extension number and the procedure of the call connection control method shown in FIG. 2 for all the wireless IP telephones 63 that can be connected to the call connection control device 11. It is explanatory drawing which shows.

  The call connection control device 11 stores the extension number of the wireless IP telephone 63 that is logged in. Further, the table shown in FIG. 3 is stored. First, when an incoming call request arrives at the call connection control device 11 from the calling telephone, this procedure is started. In step S110, the call connection control device 11 confirms whether the called wireless IP telephone 63 is logged in. As a result, if logged in, the process proceeds to step S120, and if not, the process proceeds to step S210.

  In step S210, the call connection control device 11 receives the process stored in the process 1 of the wireless IP telephone 63 that is the incoming call target (for example, in the case of the extension number 2002, the incoming call 090-XXXX in the table shown in FIG. 3). -Transfer to the telephone having the telephone number of XXX2), and proceed to "END".

  In step S120, the call connection control device 11 confirms whether the called wireless IP telephone 63 is busy. As a result, if it is busy, the process proceeds to step S220. If not, the process proceeds to step S125.

  In step S220, the call connection control device 11 performs a busy tone to the calling telephone in the table shown in FIG. 3 in the processing stored in the processing 2 of the wireless IP telephone 63 to be received (for example, in the case of the extension number 2002). ) And proceed to “END”.

  In step S125, the call connection control device 11 calls the wireless IP telephone 63 that is the incoming call target, and proceeds to step S130.

  In step S <b> 130, the call connection control device 11 confirms whether a normal response is transmitted from the called wireless IP telephone 63. As a result, if a normal response has arrived, the process proceeds to step S135, and if not, the process proceeds to step S230.

  In step S230, the call connection control device 11 receives the process stored in the process 3 of the wireless IP telephone 63 that is the incoming call target (for example, 03-XXXX for the extension number 2002) in the table shown in FIG. -Transfer to the telephone having the telephone number of XXX2), and proceed to "END".

  In step S135, the call connection control apparatus 11 makes a call with the wireless IP telephone 63 that is the incoming call target, and then proceeds to “end”.

  In this way, when the wireless IP telephone 63 requested to receive an incoming call is not logged in, or when the wireless IP telephone 63 requested to receive an incoming call is busy, the wireless IP telephone 63 requested to receive an incoming call is logged in. Different processing can be performed for each cause of failure to receive a call when a normal response is not returned to the call.

  In the above procedure, first, in step S110, it is confirmed whether or not the wireless IP telephone 63 requested to receive an incoming call is logged in. By doing so, calling to the wireless IP telephone 63 that is not logged in is performed. Can be prevented.

  In step S130, if a normal response is not returned even though the user is logged in, the user has been out of the service area at least at the time of the previous login confirmation. It is more likely that the user is in the vicinity of the wireless LAN base station 64 than outside the service area in step S110, and the processing (processing 1 and processing 3 in the present embodiment) is set so that this characteristic can be utilized. A good telephone system can be constructed. Specifically, as in the extension number 2002 of FIG. 3, when the out-of-service time is long (process 1), the incoming call is forwarded to the mobile phone, and when it is just out of service (process 3), it is in the vicinity of the wireless LAN area. By setting the incoming call forwarding to the fixed telephone, the opportunity of access with the person on the called side can be further improved.

  As described above, according to the present invention, in the telephone system using the wireless LAN, the call connection that improves the access opportunity with the called party by changing the processing performed when the incoming call cannot be made for each cause of the incoming call cannot be made. A control device and a call connection control method can be provided.

  In the above-described embodiment, the extension number is used for the identifier of the wireless IP telephone 63 (the leftmost column of the table shown in FIG. 3), but the user name, MAC address, IP address, etc. are used. Also good. In addition, in order to identify the reason why the wireless IP telephone 63 cannot receive an incoming call, conditional judgments such as “logged in”, “busy”, “return normal response to call” are used. Or “whether the response to the call has timed out” or the like may be used. Furthermore, as processing in the call connection control method, out-of-service tone transmission, busy tone transmission, incoming call transfer to a mobile phone, and incoming call transfer to a fixed phone were used, but mail notification, incoming call transfer to another extension phone, etc. were used. May be.

It is a figure which shows the structure of an Example. It is a flowchart which shows the procedure of the call connection control method. It is explanatory drawing of the table which shows the extension number and the content of the process 1, the process 2, and the process 3. FIG.
