A full electronic telephone exchange transmits the message for the IN service and the AIN service to the SCP(S32).

Description

{The Management method of Multi Subsystem Number in Electronic Switching System}

The present invention relates to a method for operating multiple subsystem numbers in an electronic switchgear, and more particularly, by using multiple subsystem numbers when processing an intelligent network service in an electronic switchgear, an IN service and an AIN service can be used in the same system. The present invention relates to a method for operating multiple subsystem numbers in an electronic switch.

In the conventional subsystem number operation function, there is no method of implementing a service when the same subsystem number of the IN service and the AIN service is used. Therefore, the service switch is based on the service accommodated by the intelligent network service control system (hereinafter referred to as SCP). The system (hereinafter referred to as SSP exchange) was operated by separating the IN service and the AIN service into separate systems.

SCP has been developed from the above, and adopts the subsystem number operation method that accepts both the IN service and the AIN service and uses the same subsystem number, but in the case of the subsystem number operation method, the IN service and the AIN are used. Signal point code was used to distinguish SSP exchangers that accept services separately.However, this method requires not only a separate SSP exchange for each service, but also the number of SSP exchanges connected to the SCP when the number of connected SSP exchanges increases. There is a problem that must be managed by service.

Accordingly, an object of the present invention is to provide a multi-subsystem number operation method for implementing an SSP switch capable of simultaneously accommodating an IN service and an AIN service.

The ISUP block performs call processing for ISDN users.

Hereinafter, with reference to the flowchart shown in Figures 3 to 4 will be described in detail the operation of the multi-subsystem number operating method in the electronic switch according to an embodiment of the present invention.

First, the operator generates a local subsystem number in all ASP_Ts configured in the electronic switchboard through the operator terminal 110 and stores it in the No. 7 protocol processing unit 121 of the ASP_T 120.

Here, in order to generate the local subsystem number, in case of an IN service, a subsystem number and an ASP-T number for an intelligent network service are input. In case of an AIN service, a subsystem number and ASP_T are input for each AIN service key number. (S10).

The subsystem generated through the above process processes the process of making the in-service state through the initialization process with the SCCP block in the ASP_T 120 in the SCCP block of the ASP_7 (130) (S12).

In addition, when an operator needs to generate intelligent network data for SCP in order to perform intelligent network call processing, first create a SCCP signaling point for the SCP, and generate a subsystem number to serve the SCP for which the signaling point is generated. . At this time, in the case of IN, only a predefined subsystem number needs to be input, but in the case of the AIN service, the AIN service key number must be input together (S14).

When the signal point and the subsystem for the SCP are created through the above process, a global title routing case (GTRC) and a global title series (GTS) are generated to translate the global title (GT) (S18). .

Here, the GTRC uses the intelligent network service to separate traffic into several SCPs, which uses the SCP signal point code and the subsystem number of the intelligent network service, and in the case of AIN, uses the AIN service key number.

The GTS usually uses prefix information of an intelligent network as a system internal identification number assigned to the corresponding intelligent network service. When generating the GTS, a translation type (TT) and GT and GTRC data are used, and in the case of an AIN service, an AIN service key number is used.

When the signal link is activated, the intelligent network data generated through the above process is also activated with the SCCP signal point, and the subsystems provide network management messages (SST: Subsystem Test, SSA: Subsystem Allow, SSP: Subsystem Prohibit) between SCPs. If it is in a normal state while receiving it, make it active.

In this state, when the call processing message is received by the application processing unit 201 of the NO.7 protocol processing unit 121 of the ASP_T 120, the intelligent network call processing procedure is performed (S22).

Hereinafter, the intelligent network call processing procedure will be described in detail with reference to the flowchart shown in FIG. 4.

In the method of processing an intelligent network message in the intelligent network protocol processor No.7, when a call processing message is received from the application processing unit 201, the application processing unit 201 analyzes the intelligent network service requested by the call from the call processing message, The subsystem number and the general title number for the service are allocated and transmitted to the TCAP 203 (S26).

At this time. In the case of IN service, since the INAP / ASE block 202 exists for each service, the relevant subsystem number can be assigned. In case of the AIN service, the AIN service key number is assigned because only one INAP / ASE block 202 exists. To retrieve and assign multiple subsystem numbers, and to form the same dialog for one call, the call start message is assigned to a dialog number and transmitted to the TCAP block 203.

The TCAP block 203 processes the dialog function, component function, and transaction function of the TCAP in the received intelligent network call processing message and transmits the SCCAP block 204 (S27).

The SCCP block 204 performs the global title translation procedure according to the SCCP data generated by the operator when the destination address portion needs the global title translation in the received message (S28).

Here, the global title translation procedure finds GTRC data that matches the TT and GTS data generated by the operator with the TT and GTS data of the subsystem number and the global title data included in the received intelligent network message, and assigns the corresponding GTRC data. After searching the signal point of the SCP, the corresponding SCP signal point number and the received subsystem number are allocated and transmitted to the MTP L1 / L2 / L3 block 205.

Thus, MTP L1 / L2 / L3 (205) performs a function to reliably deliver the message to the SCP.

As a result, the electronic switch can transmit a message for the IN service and the AIN service to the SCP.

On the other hand, the intelligent network message received from the SCP is performed by the internal protocol processing function in the reverse order of the above-described transmission procedure.

According to the present invention as described above, in order to solve the inconvenience of having to install and operate the electronic switchboard for each system in order to perform the IN service and the AIN service, the IN service and the AIN service are provided through one electronic switchboard. In addition to this, the MMC command allows the operator to freely assign and release subsystem numbers for AIN services.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
