The present invention relates to a method for rejecting a bad user of an exchange, and more particularly, to a method for rejecting a bad user of an exchange that blocks a bad user who wants to receive services by accessing a company network from a third party network.

In this regard, in light of the increasing current and future trends of communication service providers, there is a need to fundamentally block some rogue users who are expected to supply services through multiple networks.

Therefore, an object of the present invention is to record the subscriber in the Black List Database (Black List Data Base) when the subscriber connected to the third party network shows the behavior such as the late payment of the fee while using the service. It is an object of the present invention to provide a method for rejecting a bad user of an exchange that enables a user to select and provide a service by automatically rejecting a call processing of a corresponding subscriber.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention for achieving the above object is as follows.

Referring to FIG. 1, FIG. 1 is a block diagram for explaining, in hardware, a method for rejecting a bad user of an exchange according to the present invention, wherein the operation processor 100, the relay line control processor 101, The translation processor 102, the trunk line connection unit 103, the switch connection unit 104, the signal connection unit 105, the announcement broadcast connection unit 106, the black list database 107, and the terminal 108 It is made to include.

The present invention thus made will be described with reference to FIGS. 2 and 3 as follows.

First, when the relay line control processor 101 receives a call connection request through the relay line connection unit 103 from another network, the relay line control processor 101 continuously receives the incoming call number through the switch connection unit 104 and the signal connection unit 105 after responding to the connection.

Next, the relay line control processor 101 receives the caller ID of the subscriber who requested the call connection by using the signal connection unit 105 to send the call forwarding request to the other network and receives the caller number again in the same manner as described above. (102) determines whether or not the corresponding number is registered in the black list database (107) to determine whether or not to register. If the registration is registered, the announcement announcement is pre-recorded to the subscriber by using the announcement broadcast connection unit (106). If not, the number translation processor 102 connects the normal channel through the number translation process.

When the operator receives a blacklist subscriber registration request from the terminal 108 connected to the operating processor 100, the number translation processor 102 searches the blacklist database 107 to determine whether to register, and the blacklist database 107. ) Is already registered to the operation processor 100 to notify the pre-registration and output through the terminal 108, if not registered to the black list database 107 list to operate through the terminal 108 The processor 100 notifies the operator of the completion of registration.

2 and 3 are flowcharts showing step by step an embodiment of a method for rejecting a bad user of an exchange according to the present invention.

First, as shown in FIG. 2, when the relay line control processor 101 receives the call connection request 200 through the relay line connecting unit 103 from another network, the relay line control processor 101 continuously transmits the called number digit to the switch connecting unit 104 and the signal connecting unit. Received through the 105 and after the completion of the reception 201, using the signal connection unit 105 receives the calling number of the calling party to the other network (202) to receive the caller's calling number again requesting the call connection (203) to receive the number translation The processor 102 determines whether or not the corresponding number is registered in the black list database 107 by searching (204) to determine whether or not to register (205). The recorded announcement is transmitted (206), and if not a blacklist subscriber, the recorded announcement is connected to the normal channel through the number translation process by the number translation processor 102 (207).

Next, when the operator receives the black list subscriber registration request 208 from the terminal 108 connected to the operation processor 100 as shown in FIG. 3, the number translation processor 102 searches the black list database 107 for the retrieval request 209. If it is already registered in the database and the registration is already registered in the database, the operation processor 100 notifies the pre-registration through the terminal 108 to output (212) and, if not registered, the black list database 107 Register 211 to the list, and notifies the operator through the terminal 108 by the registration completion notification (213) to the operation processor (100).

The registration and search in the black list database 107 will be described in detail as follows.

The structure of the black list database 107 uses a relational data model represented by a table structure in the form of a two-dimensional array, and an index access using a pointer is used as a relation approach. Use technique.

The black list database 107 should be divided into a station number and a called number and processed. The capacity of the black list database 107 is as follows.

Maximum database capacity acceptable: 7 Mbyte-600,000 subscribers.

Database capacity based on exchange capacity: 1 Mbyte-80,000 subscribers.

As described above, the present invention enables other blacklist subscriber registration and call service selection functions.

It is also possible to have a separate computer system to manage the black list database 107 without using a database inside the exchange.

As described above, the present invention assures stable supply of the communication service business by fundamentally blocking some of the poor users expected when the service is supplied through multiple networks in view of the increasing trend of the communication service providers. It can work.

Claims (1)

When a call connection request is received, after answering the connection, it continuously receives the called number digit, and after the reception is completed, receives the calling party number of the subscriber who requested the call connection by sending the calling number to the other network and receives the call number again. Determining whether to register by requesting a search whether the information has been registered in the application (200, 201, 202, 203, 204, 205); In step 200, 201, 202, 203, 204, and 205, if the number is registered as a black list, sending the pre-recorded announcement to the corresponding subscriber; otherwise, connecting to the normal channel through the number translation process (206, 207); If a blacklist subscriber registration is requested, requesting to search the blacklist database to determine whether to register (208, 209, 210); If the user is already registered in the black list database, the user can be notified of the registration. If not registered, the user is registered in the black list database list and outputted to the operator so that the bad user of the exchange includes (212, 211, 213). Rejection method.
