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.

1 is a conceptual diagram of a network structure of a general intelligent network system, and 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 mobile switching point (MSC) Center 3 transmits the calling party number and the called number to the service control point (SCP) 6 using the 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, when the independent B service SLP 20 is inserted into the independent A service SLP (Service Logic Program) 10 having the A service scenario, the A service is performed. Is processed in preference to the B service (sign 30), while the B service is processed in preference to the A service when the independent A service SLP 10 is inserted into the independent B service SLP 20 having the B service 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 has to 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 even when verifying the service logic program, Because of the need for retesting, there was a problem of reducing the flexibility of the service logic program configuration, which is an important concept of the intelligent network system.

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 The present invention provides a method of processing a basic call in an intelligent network system that can support an intelligent network call processing service according to each service scenario while preventing a collision of services.

In order to achieve the above object, a method for processing a basic call in an intelligent network system according to the present invention includes a method for processing a basic call in an intelligent network system, the method comprising: determining whether a subscriber's calling number is registered in a service; Step 2, if the calling number is registered in the service, the service control system (SCP) analyzes the calling number and loads an individual service logic program stored in the service logic according to the corresponding service; The service logic program A third step of executing a flow of the service by the service gateway station (SSP); a fourth step of constructing and executing an acknowledgment message to the SSP; whether the called number of the acknowledgment message for the SSP is registered in the service; A fifth step of determining; if the service registration of the called number is not confirmed, an acknowledgment is transmitted to the SSP. Characterized in that it includes a sixth step.

The method for processing a basic call in the intelligent network system of the present invention is to load a service logic program and to receive the intelligent network call processing operation from the existing SSP (3). 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 the SSP (3). POI is performed again from the point of return (POR) that transmits the acknowledgment (Ack) of the call processing operation to the 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 3 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 or not the subscriber's calling number is registered for service (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 SSP 3 executes the flow of the service logic program 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 6 (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 of the subscriber is not registered in the SSP 3 in step 10, it is determined whether the called party number of the subscriber is registered in the service (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 error occurrence message (error acknowledgment) is composed of the MSC or the SSP 3 (step 80), and the SCP 6 sends the SSP 3 to the SSP 3. An acknowledgment is sent (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.
