Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic configuration diagram of an IP telephone system for carrying out an embodiment of an extension service providing method according to the present invention. T11 to T1i (i is a natural number) are IP extension telephones, SV is an ID authentication server, EX denotes an exchange such as PBX (Private Branch Exchange) or IP-PBX, and is connected to a LAN (Local Area Network) 1 as an IP extension network.

  Examples of the IP extension telephones T11 to T1i include a fixed telephone, a mobile phone, and a personal computer.

  The exchange EX accommodates IP extension telephones T11 to T1i as extensions via the LAN 1 and the router RT1. The exchange EX is connected to a public / private line network PNW. Further, the exchange EX is connected to a WAN (Wide Area Network) 2 as an IP public network via a router RT2. A plurality of IP public telephones T21 to T2j (j is a natural number) are connected to WAN2.

  Then, the exchange EX is connected between the IP extension telephones T11 to T1i, between the IP extension telephones T11 to T1i and the IP public telephones T21 to T2j on the WAN2, or from the IP extension telephones T11 to T1i and the public / private network. Exchange processing with the telephones TT1 to TT3 on the PNW is executed.

FIG. 2 is a block diagram showing a functional configuration of the ID authentication server SV.
The ID authentication server SV includes a database 11, an ID acquisition unit 12, and a login control unit 13. Among these, as shown in FIG. 3, the database 11 stores data representing the correspondence between the information indicating the IP extension telephones T11 to T1i and the ID numbers assigned to the IP extension telephones T11 to T1i. Yes.

  For example, when the user of the IP extension telephone T11 holds the ID card having the ID number “abab” stored as a portable storage medium over the IP public telephone T21, the ID acquisition unit 12 stores the ID number “ abb ".

  When the login control unit 13 compares the ID number obtained by the ID acquisition unit 12 with the ID number of the IP extension telephone T11 on the database 11, the user of the IP extension telephone T11 is authenticated from the comparison result. Then, the IP public telephone T21 is logged in to the exchange EX as the IP extension telephone T11.

  Next, an extension service providing method in the IP telephone system configured as described above will be described. FIG. 4 is a flowchart showing an operation procedure and contents of the ID authentication server SV when user authentication is performed to provide an extension service.

  For example, it is assumed that the user of the IP extension telephone T11 has an ID card such as an employee ID card, moves to the IP public telephone T21 on the WAN 2 and holds the ID card. Then, the IP public telephone T21 sends the ID number to the ID authentication server SV.

  The ID authentication server SV shifts from step ST4a to step ST4b, receives the ID number sent from the IP public telephone T21, and compares the received ID number with the ID number registered in the database 11. Thus, it is determined whether or not the authentication is OK (step ST4c).

  Here, in the case of authentication OK, the ID authentication server SV logs the IP public telephone T21 into the exchange EX (step ST4d). On the other hand, in the case of authentication NG, the ID authentication server SV sends a message indicating authentication NG to the IP public telephone T21 and displays it on a display (not shown) (step ST4e).

  FIG. 5 is a sequence diagram showing a transfer operation from communication between the public network PNW and the IP public telephone T21 to another extension.

  First, it is assumed that a special number transmission operation “* 11” is performed on the telephone TT1 (03-35xx-ΔΔ □□) to the public / private network PNW by the IP public telephone T21 logged into the exchange EX. (FIG. 5 (1)). Then, the exchange EX identifies the telephone number (03-35xx-ΔΔ □□) from “* 11” sent from the IP public telephone T21 via the WAN2, and this telephone number (03-35xxx). -△△ □□) captures the public / private network PNW, calls the telephone TT1, and establishes a communication link between the telephone TT1 and the IP public telephone T21 by the response of the telephone TT1 (FIG. 5 (2)) ).

  In a state in which a telephone call is made between the telephone TT1 and the IP public telephone T21, the user performs an operation for requesting transfer of the telephone call from the IP public telephone T21 to another IP extension telephone T12 in the IP public telephone T21. (FIG. 5 (3)). Then, information indicating a transfer special number and a transfer destination extension number set in advance is sent from the IP public telephone T21 to the exchange EX.

  Upon receipt of the information indicating the transfer special number and the transfer destination extension number, the exchange EX puts the communication link between the public network / private line network PNW on hold and the empty IP extension telephone T12 corresponding to the transfer destination extension number. When the blocked state is determined and it is determined that the incoming call is possible, an incoming signal is transmitted to the IP extension telephone T12.

  When the IP extension telephone T12 responds to the incoming call, the exchange EX opens the communication link of the IP public telephone T21 and connects the IP extension telephone T12 and the communication link of the held public / private line PNW. (FIG. 5 (4)).

  Thus, the communication destination of the telephone TT1 is switched from the IP public telephone T21 to the IP extension telephone T12, and thereafter the user of the telephone TT1 can continue to talk with the user of the IP extension telephone T12.

FIG. 6 is a sequence diagram showing the Return Call operation.
First, it is assumed that the IP public telephone T21 logged into the exchange EX performs a call operation to the IP extension telephone T13 (FIG. 6 (1)). Then, the exchange EX calls the IP extension telephone T13 from the telephone number sent from the IP public telephone T21 via the WAN 2 (FIG. 6 (2)).

  On the other hand, when the IP extension telephone T13 is busy (FIG. 6 (3)), it is assumed that the user of the IP public telephone T21 performs an operation for requesting a Return Call to the IP extension telephone T13. Then, information indicating a return call special number set in advance is sent from the IP public telephone T21 to the exchange EX (FIG. 6 (4)).

  The exchange EX analyzes the Return Call special number, and when it is determined that the IP extension telephone T13 can receive a call, the exchange EX transmits an incoming signal to the IP extension telephone T13 and transmits an incoming signal to the IP public telephone T21.

  Thereafter, when the IP extension telephone T13 responds to the incoming call and the IP public telephone T21 answers, the exchange EX forms a communication link between the IP public telephone T21 and the IP extension telephone T13 (FIG. 6 (5)).

  As described above, in the above-described embodiment, the ID number input by the user of the IP extension telephone T11 is acquired by the IP public telephone T21 on the WAN 2 by the ID authentication server SV, and this ID number and the registered ID on the database 11 are acquired. The user of the IP extension telephone T11 is authenticated by comparing the number. In the case of authentication OK, the IP public telephone T21 is logged into the exchange EX as the IP extension telephone T11.

  Therefore, the user of the IP public telephone T21 requests the desired extension service only by performing a key operation for starting the desired extension service such as calling a special number, transferring, and Return Call while logged in to the exchange EX. Can be executed. For this reason, it is possible to use the extension service with the IP public telephone T21 even when the user is away from home, and this greatly improves the convenience for the user. Furthermore, since the user authentication is performed using the ID number prior to the use of the extension service, the security for the use of the extension service can be enhanced.
