Description

Device for splitting routing between stations according to subscriber type and its method {Device for split routing of inter-office signaling depend on subscriber line category and method

The present invention relates to an apparatus for separating signal routes between stations according to subscriber types and a method thereof. More specifically, the present invention relates to a general electronic telephone network (hereinafter referred to as PSTN) and an integrated telecommunication network (hereinafter referred to as ISDN). The present invention relates to a method of maintaining and processing a station-to-station signaling system according to a subscriber type when outgoing call processing of a subscriber call in a switching system.

In general, when a subscriber call is input to a single station exchange, the single station exchange translates the station number for the call generated by the subscriber and connects the outgoing route.

At this time, the subscriber may be divided into PSTN or ISDN subscriber according to the type of subscription, and the PSTN subscriber transmits the call generated by using the 'R2 signal' route and the ISDN subscriber using the integrated information network user part (hereinafter referred to as ISUP) route. It can be said that it is preferable.

However, there are no outgoing routes for these subscriber types.

In other words, the outgoing relay in the current single station exchanger attempts to connect to this route if there is an empty route in the other exchange system, if the other exchange system is determined.

Accordingly, if a call is generated by an ISDN subscriber and the connected route is called an R2 route, the exchange system receiving the call must convert the protocol to the ISDN protocol.

If this process occurs frequently when connecting a single call in the network, not only the transmission speed is lowered, but also the possibility of transmission error increases, which causes a problem of call truncation.

SUMMARY OF THE INVENTION In order to solve the conventional problems as described above, an object of the present invention is to be able to distinguish and process corresponding inter-station signaling schemes according to subscriber types in different inter-station signaling schemes during subscriber outgoing call processing.

In other words, during outgoing call processing of subscribers, connection routes are divided according to PSTN and ISDN subscribers.

In order to achieve the above object, the present invention provides a station number translation unit for translating a station number to determine outgoing routing in a corresponding exchange system among a plurality of other exchange systems to which the generated call is connected when a call is generated from subscribers; When the outgoing route is determined through the station number translation unit, a route determination unit for determining a route of a signaling method to be transmitted to the exchange system of the determined side and a route to be transmitted according to the route determined by the route determination unit 12 are separated. A terminal exchange unit having a route separation unit configured to directly receive subscribers and perform a call processing function;

Translating the direct telephone number of the incoming route routed call transmitted from the single station exchange, characterized in that it comprises a relay exchange for connecting to the outgoing route.

In addition, the present invention for achieving the above object is, when the subscriber call is generated by a single station exchange directly connected to the subscriber, the first step of translating the station number for the generated call to select the outgoing route;

A second step of determining a subscription type of a subscriber corresponding to the originating call when the outgoing route is selected through the first step;

If the type of subscription is determined in the second process, the method includes a third process of transmitting / receiving a call by selecting / separating a route for each station signaling method corresponding to the type of subscription.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an apparatus for separating signal routing between stations according to the present invention, comprising a single station exchanger 1 which is an exchange system that directly receives subscribers and performs a call processing function;

And a transit switch 2, which is an exchange system for translating the direct telephone number of the incoming route routed call transmitted from the single station exchange 1 and then connecting to the appropriate outgoing route.

When the call is generated from the subscribers, the single station exchanger 1 translates the station number to determine an outgoing routine to the corresponding exchange system among a plurality of other exchange systems to which the generated call is subscribed. ;

A route determination unit 12 for determining which signaling route is to be transmitted to the exchange system of the determined route when the outgoing route is determined through the station number translation unit 11;

The route determination unit 12 includes a route separation unit 13 for separating routes to be transmitted according to the route determined.

For reference, the station number translated by the station number translation unit 11 is a number managed to determine the type of call processing (eg, home call, outgoing call, incoming call, etc.) or the type of service processed by the exchange system. When the call is generated from the subscriber, the route determination unit 12 determines whether the subscriber who generated the call is a PSTN subscriber or an ISDN subscriber to determine the route to be transmitted. It is easy to see whether it is a kind.

When the subscriber type is detected, the call is transmitted to the corresponding route according to the subscriber type. The general PSTN network subscriber call is transmitted to the 'R2 route', and the ISDN network subscriber call is transmitted through the ISUP route.

An operation process of the inter-station signal route separation processing apparatus of the present invention having the above configuration will be described with reference to FIG.

When the subscriber call is received, the end-station exchanger 1 first translates the station number for the subscriber from which the call originated (11) to determine the route of the corresponding exchange system to be dispatched among a plurality of other exchange systems (S1).

When the other exchange system (the relay switch 2 in FIG. 1 corresponds to the relay switch 2 in the following) is determined, the route to be connected to the relay switch 2 is determined (12). In order to determine the type of subscription for the currently entered subscriber call (S2) and transmits the generated call to the route by the inter-station signaling method corresponding to the subscription type.

That is, the PSTN subscriber branches to the R2 route, and the ISDN subscriber branches to the ISUP route (S3).

For reference, the algorithm for performing the above functions may be implemented in the terminal exchange 1 directly receiving the call generated from the subscriber, and the relay exchange 2 receiving the call thereafter is basically a subscriber type. It does not need to be considered because it uses a route according to.

As described in detail above, in the present invention, when different inter-station signaling methods exist in an all-electronic switching system accommodating general PSTN and ISDN subscribers, call processing can be performed by corresponding inter-station signaling methods according to subscriber types even for the same station number. This not only provides ISDN data and additional services smoothly, but also provides the advantage of increasing call processing efficiency by minimizing signal conversion.

In addition, a preferred embodiment of the present invention is disclosed for the purpose of illustration, those skilled in the art will be able to make various modifications, changes, additions, etc. within the spirit and scope of the present invention, such modifications and modifications belong to the following claims You will have to look.
