DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for providing a personal communication service to a personal communication user.

[0002]

2. Description of the Related Art A case in which a personal communication service is provided on a fixed telephone network will be described as an example. In a fixed telephone network, a telephone number corresponds to a fixed number. FIG. 3 is an example of a system configuration of a personal communication service. FIG. 4 shows an example of providing a service to a personal communication user when the conventional technique is used in FIG. 3 and 4, 1-L 1-
2 is a personal communication user, 2-1 and 2-2 are communication terminals accessed by each personal communication user, and 3-1 and 3-
2 is a switching node for accommodating communication terminals, 4 is a fixed telephone network for providing personal communication services, and 5 is a switching node 3 which manages service contract contents for personal communication numbers and correspondence between personal communication numbers and routing addresses. It is a personal communication service subscriber information management function (here, a database). Further, FIG.
, PTN1 and PTN2 are personal communication numbers,
RA2 is a personal communication user 1 using PTN2.
1 is a routing address indicating the designated destination.

[0003] An example of service provision according to the prior art will be described below with reference to Figs. The personal communication user 1-2 registers its own PTN2 and the routing address RA2 in the database 5 from the communication terminal 2-2 in advance. Thereafter, the personal communication user 1-1 calls the PTN 2 to communicate with the personal communication user 1-2 (), and when the switching node 3 receives the signal, the switching node 3 sends the call to the database 5 to the personal communication user 1-1. An inquiry about the service contract contents and an inquiry about RA2 to PTN2 are made (). The switching node 3 makes a call connection to the personal communication user 1-2 using the RA2 obtained from the database 5 and the personal communication number (). This is performed from the node 3-2 to the database 5 (). Therefore, when actually providing a service, it is necessary to guarantee in some way the consistency between the service that can be provided by the terminal accessed by the personal communication user and the service that can be requested (contracted) by the user.

[0004]

In the prior art, FIG.
No control is performed on the consistency between the contract service of the personal communication user stored in the database 5 and the service that can be provided by the communication terminal. Therefore, a problem arises, for example, in a case where the receiving personal communication user has contracted for the bearer requested by the calling party, but the terminal that actually receives the call cannot be provided. The present invention aims to improve this point.

[0005]

According to the present invention, there is provided a call control function for providing a service to a personal communication user by a switching node accommodating a plurality of communication terminals each having a fixed number. The personal communication user accessing the communication terminal is assigned a personal communication number for identification, and the service contract contents for each personal communication number are managed by the personal communication service subscriber information management function. In a service providing method in personal communication, a switching node is provided with a terminal service subscriber information management function for managing service contract contents of a communication terminal to be accommodated and a provided service determination function, and a personal computer connected to one of these communication terminals is provided. When a communication service is requested for a communication user, this exchange The service provision determination function referred to above refers to the service contract contents of one communication terminal from the terminal service subscriber management function, and the service contract contents of the personal communication user for whom the communication service is requested are managed by the personal communication service subscriber information management. If the requested service is included in both service contracts with reference to the function, the provision of this service is determined, and the determined service is transferred to the personal computer for which the communication service is requested under the control of the call control function. If the requested service is not included in either of the service contracts, it is determined that the service is not permitted and the incoming call is discarded. Provided.

[0006]

According to the present invention, a service determining function for determining a service to be provided with reference to the personal communication service contract information and the terminal service contract information is provided in the switching node. When the personal communication user originates and receives a call, the determination function determines the service to be provided, and the call control function provides the personal communication service using the result. Therefore, the above object is achieved.

[0007]

FIG. 1 shows an example of service provision when the service provision method of the present invention is used in the system configuration of the personal communication service of FIG. In FIG. 1, 6 is a provided service determination function, 7 is a terminal service information management function, and 8 is a call control function. Here, as shown in FIG. 2, the outgoing / incoming personal communication users 1-1 and 1-2 have contracted for the 64k bearer service and the telephone, and the terminal accessed by the called user 1-2 has contracted the incoming call transfer with the analog terminal. A description will be given of the case in which For example, consider a case where the calling user 1-1 requests the receiving user 1-2 to receive a call using the 64k bearer service. At this time, the provided service determination function 6 of the destination switching node refers to the contract contents of the user 1-2 in the database 5 and the contract service of the terminal 2-2 in the terminal service subscriber information management function 7, and the personal communication user 1 Check whether the call can be received to -2. In this case, since a 64k bearer cannot be provided because an analog terminal is used, the provided service determination function 6 determines that this incoming call is not permitted. Using this result, the call control function 8 discards the incoming call to the user 1-2.

On the other hand, when an incoming call is requested, the incoming call is connected to the user 1-2 because it can be provided. Also, in this case, the terminal 2-2 has contracted for call transfer, but the personal communication user 1-2 has
Arrives at the terminal 2-2 as it is (user 1
-2 If the customer has contracted the call transfer, the call transfer is performed. ). Thus, the personal communication service is provided to the personal communication user.

[0009]

As described above, according to the provided service determining function of the present invention, when a communication service is requested to a personal communication user connected to one communication terminal, this one communication terminal is requested. Refer to the service contract contents of the terminal service subscriber management function from the terminal service subscriber management function, and refer to the service contract contents of the personal communication user for whom the communication service was requested from the personal communication service subscriber information management function. Decide to provide this service if it is included in the content and decide not to grant this service if the requested service is not included in either of the service contracts. ing. Therefore, it is possible to select a service that can be provided by the terminal accessed by the personal communication user from the services that can be requested by the personal communication user, and to provide a personal communication service that matches the capability of the terminal. .
