BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call processing method for a packet service of an all-electronic exchanger capable of ISDN (Integratd Service Digital Network) packet service.

Currently, most of the proposed exchanges are equipped with a subsystem for each associated function. That is, the subsystem for packet service, no. 7 system subsystem and a subscriber matching subsystem, which are related functions among the functions provided by the exchanger, are formed into one subsystem, there is a case where assistance of another subsystem is required when performing an arbitrary function. In such a case, the exchange performs a communication process by connecting the physical path between the subsystems through the central network, INS (Interconnection Network Subsystem) in the exchanger connecting the subsystems. An exchange having an ISDN function also has a similar processing structure.

When a packet service is provided in an exchange having such a processing structure, a physical connection between the subscriber matching subsystem and the packet service subsystem is performed through a central network connecting the physical paths between the subsystems provided in the exchange To provide services. That is, the sub-system for subscriber matching process performs matching processing with a subscriber for providing a packet service, requests packet service for the packet service subsystem in order to provide the packet service to the subscriber, And provided to the subscriber through subsystem for subscriber matching processing.

If an error occurs in the subsystem for the packet service due to the above-described processing structure, the former electronic exchange operating as described above can not provide the packet service at the exchange at all.

Therefore, the present invention provides a call processing method for a packet service of an electronic switching system so that a packet service can be performed using a called side subsystem after distributing packet services for each subsystem provided in an exchange. have.

In order to achieve the above object, the present invention provides a first subsystem for performing connection processing with a calling subscriber and a call processing for a packet service, a second subsystem configured identically to the first subsystem and accommodating a called subscriber, A method for setting up a packet call in a first and second subsystems, the method comprising: receiving a set-up message from the calling subscriber in a first subsystem; The first sub-system translating the number of the called subscriber included in the message; Requesting establishment of an established subscriber line in the second subsystem to which the corresponding number belongs if there is no abnormality in the service suitability of the signal; Connecting a physical path between the calling subscriber and the first sub-system; The second sub-system coupling a physical path between the first sub-systems; Wherein the second subsystem is configured to perform line setting of the called subscriber if the called subscriber line setting is requested from the first subsystem; Wherein the second subsystem is configured to connect a physical path between the called subscriber and the second subsystem and the first subsystem when the line setting of the called subscriber is completed, And performing a packet service.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a hardware block diagram for performing a call processing method for a packet service according to the present invention.

Referring to FIG. 1, a hardware configuration for performing a call processing method for a packet service of the present invention includes a calling subscriber unit 100, a subsystem 200 for performing call processing for a subscriber, A second subsystem 300 configured to receive another subscriber and configured to be identical to the first subsystem 200, and a called subscriber unit 400.

In particular, the originating subscriber unit 100 includes an ISDN subscriber terminal, and the first subsystem 200 includes a subscriber connection unit 210 for performing connection processing with the calling subscriber unit 100, A setup processing unit 230 for detecting a call destination number included in a Q. 931 setup message provided from the call control unit 220 and the calling subscriber unit 100 and providing the detected call setup number to the call control unit 120, And a switch 250 for providing a physical path for transmitting and receiving packet data in cooperation with the second subsystem 300. The second subsystem 300 includes the first subsystem 300, The second subsystem 300 is configured to be compatible with the first subsystem 200, so that it is possible to perform a packet service using the called subsystem, that is, the second subsystem 300.

FIG. 2 shows a detailed flow chart illustrating a preferred embodiment of a call processing method for packet service of a full electronic exchanger of the present invention.

In FIG. 2, the calling subscriber unit 100 provides a Q.931 setup message to the first subsystem 200 (S1). Q. The 931 setup message is provided to the setup processing unit 230 of the first subsystem 200 and the setup processing unit 230 of the first subsystem 200 performs the service channel setup while the Q.931 setup message (S2) to the call control unit 220 of the first subsystem 200 and requests number translation (S3).

When the called subscriber number is provided from the setup processing unit 230, the call control unit 220 of the first subsystem 200 searches for the service suitability of the corresponding number, and if there is no abnormality in the search result, 300 to the call control unit 320 (S4).

Then, the call control unit 220 of the first subsystem 200 searches the subscriber unit 210 for a physical path request signal from the calling subscriber unit 100 (S5). If the physical path request signal is provided from the calling side subscriber unit 100 as a result of the search, the call control unit 220 of the first subsystem 200 connects the physical path between the subscriber connection unit 210 and the switch unit 250 S6).

When the call control unit 320 of the second subsystem 300 requests the call control unit 200 of the first subsystem 200 to set up the called subscriber line, the call control unit 320 of the second subsystem 300 performs line setting of the called subscriber (S7) The physical path between the subscriber connection unit 310 of the second subsystem 300 and the switch unit 350 and the packet service unit 240 is connected (S8). So that the destination packet service unit 240 can perform the packet service (S9).

As described above, according to the present invention, when a packet service is performed, a packet service can be distributed for each sub system provided in an exchange and then a packet service can be performed using the called side subsystem, It is effective.
