Abstract

PURPOSE:To make it possible to simultaneously apply network control information to many connection requesting calls and to connect the calls without restricting them by previously setting up information from a central network control information storing part in a transmission exchange. CONSTITUTION:Network control information such as connected destination number and charging information is previously set up in a storage part included in the central network control information storing part 4, and prior to the generation of a call, information is previously transferred to a network control information storing part 3 in the transmission exchange 1 through a common line signal network. When a connection request which can not be processed only by an original function part 2 in the exchange 1 is outputted from a telephone set 10, the original function part 2 for an automatic exchange in the exchange 1 connected to the call based upon the network control information stored in the storing part 3. Even when many calls following indexes such as connected destination calls and charging information are simultaneously generated, call processing can be completed in the exchange 1 and congestion between a common line signal network and the storing part 4 can be evaded.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, in a public telecommunications network, performs an index processing of connection information such as a connection destination number and charging information in response to a large number of simultaneous connection requests that require an index of connection information and charging information. The present invention relates to a network control information deploying method for completing the above in the originating exchange.

More specifically, according to the present invention, network control information is distributed from a central network control information storage unit to a large number of originating exchanges before a call is made, and new information is changed when the information is changed. The present invention relates to a method for avoiding the congestion of the common line signaling network and the central network control information storage unit by completing the index control processing of the network control information only within the originating exchange by resetting.

[0003]

2. Description of the Related Art Conventionally, in a service that requires network control information, necessary information such as a connection destination number to be converted and billing information is stored in a central network control information storage section outside a calling exchange to generate a call. In each case, it was necessary to make an inquiry from the originating exchange to the central network control information storage section through the common line signaling network for information. If this method is used as it is, for example, when the connection number is advertised through mass meteor etc. by holding an event or popularity poll, a large number of simultaneous connection request calls will occur and the common line signaling network and central network control information storage unit In order to cause congestion, there is only a method of directly setting a connection destination number or the like to be converted in advance for each calling exchange so as to avoid inquiries to the central network control unit or to perform some kind of call regulation.

[0004]

SUMMARY OF THE INVENTION In the prior art,
When a large number of calls for services that require information such as connection destination numbers and billing information to be converted occur simultaneously in multiple calling exchanges, there is a possibility of congestion in the common line signaling network and central network control information storage unit. Therefore, it is necessary to restrict the connection, such as limiting the ending number of the calling telephone, and as a result, the call completion rate is lowered.

An object of the present invention is to solve the above-mentioned problems of the prior art, and at the same time, it is possible to add network control information to a large number of connection request calls, and to connect without restricting the calls. It is in.

[0006]

[Means for Solving the Problems] The connection destination number, billing information, etc. to be converted from the central network control information storage unit are set in advance in the network control information storage unit of each originating exchange, and the telephone subscriber sets the connection destination. When connecting via a switch, the dial number is sent to the network control information storage unit in the originating switch, and the network control information storage unit searches for the connection destination number and charging method based on the received dial number. However, when the transmission unit of the originating exchange performs connection processing by passing the necessary information to the transmission unit, and when the information in the network control information storage unit of the transmission exchange is changed, the central network control information storage unit Set new information again for each exchange. To summarize this, the pre-distribution of information from the central network control information storage unit to each originating exchange not only enables a large number of simultaneous call processing, but also the connection in the network control information storage unit in many originating exchanges. Information such as the destination number can be set and changed almost at the same time.

[0007]

By providing the network control information storage unit in the originating exchange and enabling the information to be enjoyed without making an inquiry for information to the central network control information storage unit via the common line signaling network every time a call occurs, It is possible to avoid congestion of the common line signaling network and the central network control information storage unit when a large number of calls are simultaneously generated in a large number of originating exchanges. Further, as in the conventional case where the central network control information storage unit performs the information index every time, the flexible service control becomes possible.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing an embodiment of the present invention,
Reference numeral 1 is an originating exchange, 2 is an original function part of the originating exchange, 3 is a network control information storage unit, 4 is a central network control information storage unit, and 10 is a telephone.

The operation of this embodiment will be described with reference to FIG. Network control information such as connection number and billing information required for call processing is set in advance in the storage unit of the central network control information storage unit 4, and the network control information storage unit 3 of the originating exchange 1 is set in advance before a call is generated. The information is transferred to the terminal via the common line signal network. When there is a connection request from the telephone set 10 that cannot be processed only by the original functional unit 2 of the originating exchange 1, the original functional unit 2 of the automatic exchange of the originating exchange 1 will change the network control information stored in the network control information storage unit 3. Based on this, call connection processing is performed.

FIG. 2 is a connection system diagram showing an embodiment of the present invention in which required information is provided from the central network control information storage unit 4 to each originating exchange 1. As shown in FIG. 2, by providing the network control information storage unit 3 of all originating exchanges with data necessary for call processing from the central network control information storage unit 4 to each originating exchange 1, each time a call connection request is generated. It is not necessary to make an inquiry about information to the central network control information storage unit 4.

[0011]

As described above, according to the present invention,
Even if a large number of calls accompanied by indexes such as connection numbers and billing information occur simultaneously in the public telephone communication network, call processing can be completed in the originating exchange, and congestion in the common line signaling network and central network control information storage unit Therefore, there is an advantage that it is possible to promptly deal with connection destination guidance in mass media by holding an event.
