Abstract

PURPOSE:To obtain a subscribed member retrieval system in which it is not required to store data for retrieval of a subscribed member at its own station in the case of various connection services when each gate station of its own network detects an incoming call from another network. CONSTITUTION:The subscribed member retrieval system ins provided with a database retrieval device 13 registering and retrieving the content of the connection service of its own network to each subscribed member belonging to another network and one or plural gate stations 11 using the database retrieval device 13 to retrieve and discriminate the content of the connection service to the subscribed members and the data of the subscribed members are retrieved by a database at the outside of the gate station.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member subscriber search system used in exchange processing of a centralized exchange of a stored program control system, and particularly, a member preferably used in a gateway station with other communication carriers. Subscriber search system.

[0002]

2. Description of the Related Art For example, it is assumed that separate communication carriers X and Y have their own communication networks and their own member subscribers. Some of the subscribers are members only to X, and some are both X and Y members. A person who is a member of both X and Y can communicate not only with the member of X but also with the member of Y. On the other hand, a person who is a member of only X cannot normally make a call to a member of Y.

In this way, when various connection services are provided to member subscribers by the central office switch of the stored program control system, what kind of services the member subscribers may receive in their own network at the stage of incoming call. It is necessary to check whether it is possible and perform call processing accordingly. Conventionally, each exchange of each gateway station uses the member subscriber data stored in its own memory to perform a service content search process for the member subscriber as a process in the exchange.

[0004]

As described above, conventionally, each gateway exchange has been configured to store the member subscriber data in its own memory and perform the retrieval process. Therefore, in the initial stage of interconnection with other operators, each of the small number of gateway stations must accommodate the data of member subscribers in a fairly wide range, which causes a problem that the capacity of the memory in the exchange is significantly reduced. there were.

Further, when a new gateway station is opened, the member data of the member who is in the area under the control of the original gateway station will be shared by the new gateway person. There was also a problem that the user data had to be transferred to the memory of the new gateway station.

It is therefore an object of the present invention to provide a member subscriber search system in which each gateway station does not need to store data of member subscribers.

[0007]

According to a first aspect of the present invention, a database in which the contents of a connection service in the own network for each member subscriber belonging to another network is registered, and the database is searched to connect to the member subscriber. The member subscriber search system is equipped with one or more barrier stations that determine the content of the service.

That is, according to the first aspect of the invention, the gateway station is allowed to access the database in which the contents of the connection service in the own network for each member subscriber belonging to the other network are registered so that each gateway station can access the database. It eliminates the need to store member subscriber data and achieves the aforementioned objectives.

It is necessary that the database is arranged so that it can be commonly used by each gateway station of its own network. If this database is arranged in only one place in the own network, the processing such as the member subscriber's subscription and the change of the service contents becomes easy.

[0010]

EXAMPLES The present invention will be described in detail below with reference to examples.

FIG. 1 shows a main part of a member subscriber search system according to an embodiment of the present invention. Each gateway exchange 1 of the own network 10 that constitutes this system
1A and 11B are gateway station exchanges 21A and 21 of the other network 20.
In addition to being connected to B, it is connected to a database search device 13 provided in the own network 10 via data links 12A and 12B. The database search device 13 is a CPU
(Central processing unit) is provided, and data of member subscribers such as caller numbers of subscribers who can connect to the own network 10 are stored in a storage device (not shown) such as a magnetic disk. There is.

FIG. 2 shows the processing flow of the gateway exchange and the database. It is assumed that a subscriber α in the other network 20 shown in FIG. 1 makes a call to a subscriber β in the own network 10. For example, it is assumed that the gateway exchange 11A of the own network 10 detects an incoming call due to this. The gateway exchange 11A sends the caller number of the other network 20 to the database search device 13 (step S101). The database retrieval device 13 retrieves the data of the member subscriber in the storage device and returns the result to the relevant gateway exchange 11A (step S102). The gateway exchange 11A determines the service for the subscriber α according to the returned result.

For example, the subscriber α of the other network 20 is the own network 1
Even if the user desires to communicate with the subscriber β of 0, if the communication contract with the own network 10 is not made, the caller number of the subscriber α is stored in the storage device in the database search device 13. It has not been. Therefore, the gateway exchange 11A does not connect to the subscriber β. On the other hand, if the subscriber α has a contract for communication with the own network 10, the gateway exchange 11A will establish a connection with the subscriber β.

Of course, other connection services may be registered in the database, and it is natural that various connection services can be realized according to the search result of the database search device 13.

[0015]

As described above, according to the present invention, since the database for registering the contents of the connection service in the own network for each member subscriber belonging to the other network is prepared,
Data can be centrally managed, and it is possible to easily manage new registrants and install new gateway stations, compared to the case where each gateway station independently manages data of member subscribers. There is an advantage that.

Further, according to the present invention, since the data of the member subscribers are stored in the database, the search function of the member subscribers can be realized without squeezing the memory capacity of each exchange.
