BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of setting up a packet call in an all-electronic exchanger capable of ISDN (Integrated Service Digital Network) packet service.

In general, ISDN is an integrated information and communication network that provides existing voice and non-voice services. It is characterized in that the subscriber and the communication network are connected by a single line and the network is composed of digital, and the voice and the non- can do. In ISDN, both circuit switching and packet switching are possible at the same time. It provides a common connection point for existing circuit switching network and packet switching network, and it is possible to share various information resources, various information processing and communication processing in communication network, and to facilitate communication network management and management .

The ISDN adopts a digital signal composed of a basic rate channel (2B) of 64 kbps and a signal channel (D) of 16 kbps using a line coding technique to integrate services by digitizing the transmission scheme. The B channel is a voice and non-voice data channel, and the D channel is a call control channel.

In this ISDN, a packet call setup process of an ISDN packet service capable of ISDN packet service will be schematically described as follows.

In order to provide a packet service, the entire electronic exchange capable of ISDN packet service first establishes a service channel through a D channel. Then, after completing the normal line configuration process, the call request packet is transmitted through the established line, and the called party number in the call packet is translated to proceed with the process of establishing the called party line. This packet call setup process is performed sequentially, and there is a problem that the packet call setup process is time consuming.

Accordingly, the present invention provides a method of setting up a packet call of a mobile switching center that can perform a packet call setup more quickly by performing a packet call setup using a called number of a Q.931 setup message of a D channel It has its purpose.

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 of an all-electronic switching system, the method comprising: translating a number of a called subscriber included in a message when the subscriber system provides a SETUP message to the subscriber system; Requesting a subscriber line setting to the second sub-system to which the corresponding number belongs if there is no abnormality in the service suitability of the number of the called subscriber; And the second subsystem includes a step of setting a line of the called subscriber if the called subscriber line setting is requested from the first subsystem.

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

FIG. 1 shows a hardware configuration diagram for performing the packet call setup method of the present invention.

Referring to FIG. 1, a hardware configuration for carrying out a packet call setup method of the present invention includes a digital subscriber 100, a first subsystem 200 for performing connection processing with a subscriber and call processing for a packet service, And a second subsystem 300 configured to be the same as the system 200 and accommodating another subscriber.

In particular, the subscriber unit 100 includes an ISDN subscriber terminal, and the first subsystem 200 includes a subscriber connection unit 110 for performing a connection process with the subscriber unit 100, a call controller 120 A setup processing unit 130 for detecting the called party number included in the Q. 931 setup message provided from the subscriber unit 100 and providing the detected caller number to the call control unit 120, a subscriber connection unit 110 and the second subsystem 300, And a switching unit 140 for connecting the physical path with the physical path.

FIG. 2 shows a detailed flow chart illustrating a preferred embodiment of the packet call setup method of the present invention.

In FIG. 2, the subscriber unit 100 provides a Q.931 setup message to the first sub-system 200 (S1). The Q.931 setup message is provided to the setup processing unit 130 of the first subsystem 200. The setup processing unit 130 performs the service channel setup and detects the called subscriber number included in the Q.931 Setup message (S2) to call control unit 120 and requests number translation (S3).

When the called subscriber number is provided from the setup processing unit 130, the call control unit 120 searches for the service suitability of the corresponding number (4), and if there is no abnormality in the search result, (S).

Accordingly, the call control unit of the second subsystem 300 performs the line setting of the called subscriber when the called subscriber line setting is requested from the first subsystem 200, and performs the line setting of the called subscriber through the switching unit 140 The physical path between the first and second subsystems 200 and 300 is connected (S6).

As described above, according to the present invention, when a packet service is performed, a call setup is performed using a called number of a Q. 931 setup message of a D channel, thereby making it possible to perform call setup more quickly.
