Description

How to Find Interaction between Service Features in Intelligent Network

The present invention relates to an interaction discovery method for implementing a service-specific interactions manager implemented in an intelligent intelligent network switch.

Existing interaction discovery methods rely on expert knowledge of each service. Therefore, it is very difficult and complex to find interactions in this way in the intelligent network where many service features coexist. Especially, when a new service feature is added or a new service is started, it is necessary to analyze the complicated matters of each service and discover the interaction.

In recent years, methods have been studied to accurately specify services using well-defined formal specification languages and to discover interactions at this stage. Although this result is less dependent on the expertise of the service, there may be new interactions that are not found at the specification stage in the implementation phase and are difficult to find by conventional methods.

The intelligent network aims at introducing new services quickly and providing service by various service providers. As the communication network becomes more diversified and intelligent, the kinds of services provided to the users are increased, and the service designers are hindered from providing the service by affecting the various service characteristics. In this paper, we propose a systematic method for solving this problem, which is defined as the service feature interaction when the various service features affect each other and the desired service can not be received. The most desirable method for solving the service feature interaction is to detect and remove the element that causes the feature interaction before the execution step.

In the present invention, rather than relying on the expert knowledge of the service, we derive a common factor from only the characteristics of each service characteristic, and then propose to discover the interaction while observing the change that will occur in the performance stage with only these factors.

At this time, the elements are maintained or changed at each point in a stepwise manner, and the state transition diagram is useful for observing such changes.

Accordingly, it is an object of the present invention to provide a method for developing an interaction checking module capable of deriving such a state and analyzing the transition, and for connecting the intelligent network exchanger to actually discover an interaction.

The present invention is configured to configure an interaction inspection system when an existing service or a new service is started in the intelligent network, Lt; RTI ID = 0.0 > service features. ≪ / RTI >

Accordingly, the present invention includes the following three steps as a method for discovering interactions between service features of an intelligent network.

(Step 1) The intelligent network service interaction inspection system developed in the present invention is configured.

(Step 2) Assign scenario to intelligent network exchange and execute intelligent network service accordingly.

(Step 3) Interacts with the inspection module.

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

1 is a hardware configuration diagram of an interaction inspection system for discovering interactions between intelligent network service features in an intelligent network system.

When the intelligent network service feature interaction experiment is started, the interaction testing module (1) and the intelligent network switching system (5, 6, 9, 10) are prepared. The interaction checking module 1, which includes three logic for the discovery of the interactions, namely the service module 2, the subscriber module 3 and the checking process 4, The intelligent network system for executing a scenario includes a service control system (SCP) 5, a service switching point (SSP) 6, a subscriber line 9, and a user terminal 10. The SCP (5) operates on the PC and the SSP (6) refers to the intelligent network switch.

For execution of the service scenario, the user terminal 10 is connected to the SSP 6 via the corresponding subscriber line 9. Basic Call Service Manager (BCSM) 8 performs call forwarding for the basic call processing. When the intelligent network service is requested, the intelligent network service is transmitted to the SCP 5 through the intelligent network-service manager (IN-SM) We ask. The interaction checking module 1 connected to the SSP 6 for each intelligent network service performs an interaction check according to the defined logic. The configuration and operation of the interaction checking module will be described in detail in FIG.

FIG. 2 is a detailed configuration diagram of an interaction checking module 1 for discovering interactions among intelligent network service features in an intelligent network system.

The interaction checking module 11 mainly comprises a service module 12, a subscriber AHEVF 13, and a checking process 14, and each module operates in accordance with a predetermined rule. The service module 12 includes a user database 15 and a service processing unit 16. The subscriber module 13 includes a connection processing unit 17 and a subscriber processing unit 18. [

The connection processing unit 17 of the subscriber module 13 accepts an IN service process request of a particular subscriber from the IN-SM 7 in the SSP 6 when the SSP 6 performs an experimental service according to a scenario. Subsequently, the subscriber processor 18 stores the subscriber status of the call reception and called party and simulates the basic call processing.

After completing the basic processing of the connection processing unit 17 and the subscriber processing unit 18, the subscriber module 13 requests the service module 12 to search for the subscriber and the service. The service processing unit 16 of the service module 12 searches the user database 15 for the subscriber and the service according to the request of the subscriber module 13 and transmits the data to the checking process 14.

The inspection process 14 derives the state of the subscriber line through the service simulation and then analyzes the transition of the state to perform an inter-service check between the service features. A detailed description thereof will be given in FIG.

When the checking of the interaction by the checking process 14 is completed, the results of the subscriber and the service are outputted to the PC screen being executed by the interaction checking module 11 by the checking process 14. [

3 is a flow chart of the interaction discovery procedure of the IN service feature interaction interaction module.

When the checking process 14 is started 19, the subscriber line state is initialized to an idle state 20 and the request of the service is synchronized with the execution of the checking process 14. When there is a service request (21), the subscriber line state of the receiving and called party is changed (22).

The rules for detecting the interaction in the inspection process 14 are as follows.

I) If two subscriber lines are changed from the same state to the different state, they are judged to be interactions.

Ii) If the two service characteristics are completed in different DPs, they are identified as interactions.

The inspection process 14 determines the interaction according to these two rules, and performs the requested IN service features from the DP 1 for this purpose (23).

In order to perform the service characteristics of the intelligent network, it is necessary to apply rule (iii) for each DP (25) to check whether the state of the subscriber line has transitioned from the same state to the different state, (26).

As in the case of the rule i, it is checked whether the performance of the service characteristic is completed for every progress (24) of each DP (27). If all DPs are completed, the rule ii is applied (28) Inspect. If the service characteristics are normally completed in the same DP, this intelligent network judges that it does not induce the interaction (29). Otherwise, it judges it as an interaction (26).

After all the operations are completed (30), the result is displayed on the screen by the interaction checking module (1).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. It is not.

The present invention as described above finds interactions between service characteristics of the intelligent network by a method that does not depend on expert knowledge through the configuration of the IN service feature interaction inspection system, There is also an effect of finding and handling interactions over time.
