Description

V5.2 Subscriber Information Management Device using External Host in Electronic Switching System

The present invention relates to an electronic switchboard, and in particular, having a separate host for managing the V5.2 subscriber information outside the electronic switchboard that accommodates the V5.2 interface, the V5.2 subscriber information independently of the general subscriber information The present invention relates to a V5.2 subscriber information management device using an external host in an electronic switch that enables management to increase management efficiency.

Currently, electronic exchanges are used for local and local / tandom applications. Ultimately, electronic exchanges have been developed to develop into flexible exchanges in various networks such as integrated information and communication networks (ISDN) and intelligent networks. .

And, as is well known in the art, the V5.2 interface is the signaling protocol between the access network (AN) and the exchange recommended in European Telecommunication Standards (ETS) 300 and 347-1. . Here, the access network is a communication network capable of accepting analog and digital subscribers and communicating with an exchange for a V5.2 interface, and the exchange is an exchange capable of accepting subscribers by interfacing with an access network through a V5.2 interface.

On the other hand, the service of the public switched network (PSTN) or ISDN (Intergrated Service Digital Network) subscriber using the conventional electronic switchboard was only available to the subscribers who are directly connected by physical circuits to a predetermined subscriber interface device inside the switchboard.

In addition, in order to accommodate subscribers remote from the electronic switchgear, the call processing was performed by placing a sub-system equipped with both the existing electronic switchgear and software or hardware resources at a long distance. Accordingly, this sub-system has a disadvantage in that the price is high because it must have all the hardware or software resources of the existing electronic switchboard. In addition, this sub-system cannot handle processing of subscriber information, and is actually controlled by an electronic switch.

As a result, as mentioned above, the system does not have the hardware or software resources of the electronic switchboard, so that analog line state information is not only controlled on the V5.2 interface but also on the electronic switchboard without controlling direct call processing. By setting up an access network that performs a series of call setup operations for the subscribers according to the call control signal transmitted from, the system price can be reduced and the overall call control of all electronic switchboards is facilitated.

However, it is possible to manage the subscriber information for the V5.2 subscriber that is connected by using the V5.2 interface and the general public switched network subscriber connected directly through the electronic switch and the physical line by using the same subscriber information management device. Very inefficient.

Accordingly, the present invention has been made in view of the above circumstances, and has a separate host for managing V5.2 subscriber information outside the electronic switchboard that accepts the V5.2 interface, thereby providing the general subscribers of the V5.2 subscriber information. The purpose is to provide a V5.2 subscriber information management device using an external host in an electronic switch that can increase management efficiency by managing information independently.
