Abstract

PURPOSE: A method for processing a fundamental call in an intelligent network is provided to optimize the function of a service scenario and improve the stability of a system by reusing a previously embodied scenario when embodying the function of a new service scenario. CONSTITUTION: It is judged whether a calling number service of a subscriber is registered(S10). An SCP(Service Control Point) receives the registered calling number, analyzes the calling number, and loads a separate service logic program(S20). A flow of the service logic program is executed by an SSP(Service Switching Point) for providing an intelligent network service(S30). An acknowledge message is confirmed by the SCP and a service is executed(S40). It is judged whether a called number of the acknowledge message is registered in the SSP by the SCP(S50). If the service register is not confirmed, the acknowledge message is transmitted to the SSP by an MSC(Mobile Switching Center)(S60). If the calling number service of the subscriber is not registered in the SSP, it is judged whether a called number service of the subscriber is registered(S70). If the called number is analyzed and the service register is not performed, an error generation message is composed to the MSC or the SSP(S80) and the acknowledge is transmitted to the SSP by the SCP(S60).

Description

Basic Call Process In Intelligent Network System

The present invention relates to a method for processing a basic call in an intelligent network system. More specifically, in a case in which a plurality of independent service scenarios overlap in a plurality of service logic programs supported by an intelligent network system, an intelligent network call is assigned according to each service scenario. The present invention relates to a method of processing a basic call in an intelligent network system supporting a service.

In the intelligent network, the service is a method of dividing the service by the number of calling subscribers, for example, a prepaid service in which the mobile subscriber pays the call fee first, and then, for example, a regional discount service which is discounted in a specific region such as a home zone. For example, there is a method of distinguishing a service as a called number, such as a free phone such as a 080 service, a free advertising phone service for making a free call when an advertisement is heard, and a lifetime number service for assigning a specific number to an individual.

FIG. 1 is a conceptual diagram of a network structure of a conventional intelligent network system. According to the call processing method of the prepaid service of FIG. 1, when a specific intelligent network service subscriber makes a call, a service gateway (SSP) or a mobile switching point (MSC) is provided. (3) forwards the calling party's calling number and called party's number to the service control point (SCP) (6) using protocol name No-7 Protocol.

According to the call processing method of the prepaid service, the call processing process can selectively select only one service for each service scenario.

Referring to the block diagram of FIG. 2 for explaining the call processing process, in the case of inserting the independent B service SLP 20 into the independent A service SLP (Service Logic Program) 10 having the A service scenario, Is processed in preference to service B (sign 30), while service B is processed in preference to service A when the independent service A service SLP 10 is inserted into the service B SLP 20 having the service B scenario. It can be seen that (sign 30) should be. That is, logic programs A and B of overlapping services in SLP must be inserted and processed. Therefore, the general call processing process must implement the service logic program so that the existing service logic is included in the logic of the newly provided service, so that there is a conflict between services, and when the service logic program is verified, the existing verified service is retested. This reduces the flexibility of the service logic program configuration, which is an important concept of intelligent network systems.

Accordingly, the present invention is to solve the above-mentioned conventional problems, the object of the present invention is to add the original service and the case where the independent service scenario consisting of each service logic program supported by the intelligent network system is duplicated It is to provide basic call processing method in intelligent network system supporting intelligent network call processing service according to each service scenario while preventing service collision.

In order to achieve the above object, a method of processing a basic call in an intelligent network system of the present invention includes: a first step of determining whether a calling party number service of a subscriber is registered; A second step of, if the calling number is registered, a service control system (SCP) analyzing the calling number and loading an individual service logic program in which service logic is stored according to a corresponding service; A third step of executing the flow of the service logic program by a service gateway station (SSP); A fourth step of constructing and executing an acknowledgment message by the SCP with the SSP; A fifth step of determining whether a called number of an acknowledgment message for the SSP is registered; And if the service registration is not confirmed, a sixth step of transmitting an acknowledgment to the SSP.

The method for processing a basic call in the intelligent network system of the present invention loads a service logic program and receives the loaded network program from an existing SSP 30 to receive the intelligent network call processing operation. Determine the type of service through the called number. As a result of the service determination, in the case of the originating service in the point of initial (POI) that starts the call processing service, the service logic program of the calling subscriber is loaded to perform the intelligent network call processing procedure according to the logic of the service logic program, and then the SSP 30. POI is performed again from the point of return (POR) that transmits the acknowledgment (Ack) of the call processing operation to the destination digit (Dial Digit).

In case of the incoming service in the POI, the service logic program of the incoming service is loaded to perform an intelligent network call processing procedure according to the logic of the service logic program, and the POR procedure of delivering the Ack of the call processing operation to the SSP 30 is performed. do.

Therefore, if the service logic program is a duplicate service scenario, the existing service logic program is used again without modifying the previously verified service logic program due to the newly added service.

Hereinafter, a method for processing a basic call in an intelligent network system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a flowchart according to an embodiment of a basic call processing method of the present invention, which will be described below.

First, it is determined whether the calling party number service of the subscriber is registered (step 10).

Upon receiving the registered calling number from the SSP 3, the SCP 6 analyzes the calling number and loads the individual service logic program in which the service logic is stored according to the corresponding service (step 20).

The service logic program flow is executed by the SSP 3 to provide the intelligent network service (step 30).

The SSP 3 checks the Acknowledgment (Ack) message indicating the correct reception or transmission completion by the SCP 3 (step 40).

It is judged by SCP 6 whether or not the called number of the acknowledgment message is registered in SSP 3 (step 50).

Here, when the originating service subscriber performs the incoming service call, since the service logic configuration is complicated, it is necessary to first perform processing on the outgoing service and check whether the incoming number is serviced before giving a positive response to the SSP 3. desirable.

If service registration is confirmed, the process returns to step 20 to perform a process for the incoming service (step 50). However, if service registration is not confirmed, an acknowledgment is sent to the SSP 3 by the MSC (step 60).

On the other hand, if the calling party number service of the subscriber is not registered in the SSP 3 in step 10, it is determined whether the called party number service of the subscriber is registered (step 70). After that, if the service number is registered by analyzing the called number, the SLP corresponding to the service is loaded (step 20). However, if the subscriber does not register the service by analyzing the called number, an MSC or SSP constructs an error generation message (Error positive response) (step 80), and the SCP 6 receives a positive response to the SSP 3. Transmit (step 60). Accordingly, the call processing in the intelligent network system transfers the information to the SSP 3 by combining the stored information about the outgoing service and the information about the incoming service, thereby ending the processing.

As described above, for example, if the prepaid service subscriber calls the lifetime number service number, SCP (6) performs the service logic for the prepaid service such as the available time of the subscriber because the calling subscriber is the prepaid service subscriber, and then the SSP. (3) Immediately before passing the information to the check whether the incoming service, and since the incoming number is a lifetime number service, the service logic for the lifetime number is carried out to the information delivered to the final SSP (3) subscribers can call for the prepaid service By integrating and transmitting the information on the outgoing service information such as time and lifetime number service, each service logic program can be used repeatedly for a single issue.

As described above, the method of processing a basic call in the intelligent network system of the present invention has the effect of improving the optimization of the function and the stabilization of the system since the existing service scenario can be reused when implementing the new service scenario function. There is.

In addition, minimizing the modification or addition of a program when implementing a new service scenario function can achieve excellent results that reduce the maintenance, maintenance, management cost and time of the server program.

Embodiment of the present invention is for the purpose of illustration, those of ordinary skill in the art, modifications, changes, replacements will be possible through the technical scope illustrated in this specification.
