Description

[0001] METHOD OF MANAGING SERVICE FEATURE INTERACTION IN AIN SERVICE SWITCHING SYSTEM [0002]

The present invention relates to a method for managing interactions between service features in an Advanced Intelligent Network (AIN) service switching system. More particularly, the present invention relates to a method for managing interactions between service features in an intelligent network The present invention relates to a method for managing interactions between service features, which can realize a service interaction management function that is independent of addition of a new service in a service exchange system by discovering and processing interactions between service characteristics using the access degree.

In the conventional initial intelligent network, the interaction manager, which is a function for discriminating, processing and managing the interaction between the intelligent network service and the service characteristic, is not implemented. Therefore, when introducing a new intelligent network service, it is inevitable to modify the intelligent network service and service characteristics because it analyzes the interactions between the conventional intelligent network services in the intelligent network service exchange.

On the other hand, in the intelligent network, users will require various service and service characteristics, and they have to add these services quickly. At this time, the biggest problem is the interaction between service and service characteristics.

The method of solving the interactions between service and service features is largely divided into a method of discovering and solving static or dynamic in service development environment and a method of discovering and solving dynamically at the time of service execution in service execution environment.

The service development environment is a way to discover and resolve interactions with only the functions that appear in the specification of service and service characteristics, which is inconsistent with the service execution environment and is therefore limited in discovering and resolving interactions. Therefore, a method for solving the interaction in the service execution environment is required, and for this purpose, an interaction management function for inspecting and solving the interactions between the service features in the intelligent network service exchange system is indispensably required.

Accordingly, the present invention, which is devised in order to meet the above-mentioned needs, provides a method and system for interworking service characteristics using a degree of access to a service feature on resources on a network at the time of adding a new service in a high- And to provide a method for managing interaction between service features for implementing a service interaction management function that is independent of adding a new service in a service exchange system.

DESCRIPTION OF THE REFERENCE NUMERALS

10: Service Control System (SCP) 20: Service Switching System (SSP)

According to an aspect of the present invention, there is provided a method of managing interactions between service features applied to an intelligent network service switching system, the method comprising the steps of: A first step of performing an interaction management function between service features; A second step in which the interaction management unit processes interactions according to the degree of access to the shared resources in the network for each of the characteristics of the previously completed or running IN services and currently requested IN services features; And the current detection point (DP), the interaction management unit determines whether or not the mutual interaction management unit determines the mutual characteristics And a third step of processing the action.

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

FIG. 1 is a block diagram of an advanced intelligent network (AIN) system to which the present invention is applied. In particular, FIG. 1 illustrates a relationship between an interaction management function and a function to be interfaced in a service switching system (SSP)

As shown in FIG. 1, the AIN system includes a service switching system (SSP) 20 for sensing an intelligent network service and requesting service execution, and a service control system The service switching system (SSP) 20 includes a Basic Call Manager (BCM) 21, a Feature Interaction Manager (FIM) 22, , And an intelligent network-switching manager (IN-SM) 23.

The interaction management unit (FIM) 22 is constituted of one independent module in the intelligent network service switching system 20 and the service request from the basic call processing unit (BCM) 21 is transmitted from a specific detection point (DP) And is executed when it is generated. In addition, it interworks with the IN-SM (IN-SM) 23 in the intelligent network service switching system 20 to request the intelligent network service to the service control system (SCP) 3 existing in the intelligent network.

FIG. 2 is a software structure diagram of an interaction management part to which the present invention is applied. In FIG. 2, reference numeral 24 denotes a main module, 25 denotes a program segment, 26 denotes a state table ), And 27 denotes a feature table, respectively.

2, the interaction management unit (FIM) 22 includes a main module 24, a program segment view 25, a state table 26, and a feature table 27. [ The main module 24 includes a message management unit 241, an interaction processing unit 242, a feature instance management unit 243 and an FIM management unit 244. The program segment screen 25 includes a message management unit 251, A running feature checking unit 252, an occurrence feature checking unit 253, and a feature instance managing unit 254. [

The operation of the interaction management unit (FIM) 22 having the above-described configuration will be described below.

First, when a service characteristic process is requested from the basic call processing unit (BCM) 21, the main module 24 in the interaction management unit 22 manages information on the requested service characteristic through the status table 26. [ The feature instance managing unit 243 in the main module 24 carries out this work and the feature instance managing unit 243 stores and manages information of the dynamically generated features in the state table 26. [ Thereafter, the main module 24 requests the program segment 25 to determine whether the service feature interaction is via the message management unit 241 and to solve the interaction.

Thereafter, the program segment 25 performs an interaction process with reference to the feature table 27, and returns the result to the main module 24 again. This result is reflected in the service characteristic performance in the service control system (SCP)

The function of the main module 24 will be described in more detail as follows.

The main module 24 is responsible for messaging processing with other functions in the intelligent network service switching system and is responsible for handling the service characteristic interactions when a plurality of service features are required together for one intelligent network service call To the program segment 25, as shown in FIG. At this time, the main module 24 passes a call identifier and a feature name as parameters.

Thereafter, upon receiving a message for processing the interaction from the program segment 25, the main module 24 performs processing for the interaction via the interaction processor 242 and then sends the message to the service control system 10 Request service performance. At this time, the feature instance managing unit 243 maintains and manages the state table 26 for each IN service call in order to process a service feature request that is generated dynamically.

The program segments 25 are divided into several groups according to the semantic characteristics of the service characteristics. The message management unit 251 in the dual program segment 25 receives information on service characteristics and service calls from the main module 24 to determine whether or not they interact.

The program segment 25 is checked for two cases in order to discriminate the existence of the inter-feature interaction. One of the two cases is that the execution of the program segment 25 is performed in the feature checking unit 252, The examination for the interaction and the examination for the interaction that can occur between the features generated simultaneously in the same DP in the occurrence feature inspection unit 253 are the other one. At this time, in order to discriminate whether or not the user interacts with each other, the feature checking unit 252 and the occurrence feature checking unit 253 refer to the feature table 27 and perform appropriate processing actions for each service feature according to the degree of access to resources .

The running feature checking unit 252 and the occurrence feature checking unit 253 call the feature instance managing unit 254 to grasp the states of the features to be compared. At this time, behaviors that are likely to cause an interaction after the test are returned to the main module 24 with the call identifier, the serial number in the state table 26.

The state table 26 is implemented in the interaction management unit 22 for grasping the performance status of dynamically changing service features and includes a serial number of each entry, a call identifier, a service characteristic name, .

The program segment 25 searches for an entry having the same call identifier for discriminating whether or not to interact with each other, and determines whether or not to interact with each other and the processing behavior according to the existence or non-existence of other service features. At this time, the main module 24 dynamically manages the information about the generation of the intelligent network service call, the performance of the service characteristic, and the completion of the service characteristic.

The feature table 27 represents attributes of service features required for interaction management. In this feature table 8, the degree of access to the group to which each service feature belongs and the resource to which the service feature accesses are expressed.

The feature table 27 is referred to by the program segment 25 to determine service feature interactions and determine appropriate behavior and is statically managed at the time of service feature creation.

The feature table 8 has the name of the feature as the key of the table, and consists of the group to which the service feature belongs, and the degree of access to the related resource. In addition, it can have an extra attribute column for service-specific processing.

FIG. 3 is a flowchart illustrating an inter-operation management method according to an exemplary embodiment of the present invention. FIG. 3 illustrates a procedure for checking whether a call has an IN call service feature interaction when an IN call occurs in the IN exchange.

3, when a request for an intelligent network service is generated from the basic call processing unit (BCM) 21 in step 301, an interaction management unit (FIN) 22 ) Is executed. At this time, it is determined whether or not the call generated before the interaction management unit 22 is activated is an intelligent network service call 302. If the intelligent network service call is generated before the interaction management unit 22 is activated, To 309), and if it is not the intelligent network service call, the control is passed to the basic call processing unit without calling the interaction handling unit 22 (301).

In more detail, the interaction management functions (304 to 309) are generally divided into two parts, one of which is an intelligent network service characteristic that has been performed or is being performed, And the other one is the interaction processing between them when two or more service characteristics are requested at present. That is, it is checked whether there is an intelligent network service that is already being executed or has been executed (304), and the interaction is processed according to the result of the inspection (305 to 309).

As a result of checking, if there is an intelligent network service feature that has been performed or is being performed, the feature checking unit 252 is called during execution (305) and performs processing (i. E.

Specifically, an examination of the presence or absence of the interaction of the feature checking unit 252 during execution is performed on the characteristics of the features stored in the feature table 27. [ In other words, the possibility of interaction is determined according to the degree of access to the resources that can be shared in the network for each feature. In the case where the write operation is simultaneously performed for the resource as long as the two characteristics can be shared, Interactions may occur when a feature that is currently performed after performing a read operation performs a write operation. Therefore, the interaction management unit 22 must perform appropriate processing to prevent interaction. In the former case, the currently generated characteristic is rejected. In the latter case, To reprocess the feature being performed.

The checking process 305 during the execution of the feature checking unit 252 during the execution is performed for the interaction between all the service features requested in the past.

After checking whether there is an interaction with all the service features being executed (306), it is checked whether or not there is an interaction with the features co-existing in the current DP. At this time, If there are two or more features that are generated, the occurrence feature checking unit 253 is called (308) and performs processing (that is, inspection of the features that are issued together).

In detail, the occurrence characteristic checking unit 253, like the feature checking unit 252 during execution, determines whether or not an interaction exists and then determines an appropriate process for preventing the interaction. At this time, the occurrence characteristic checking unit 253 refers to the state table 26 through the characteristic instance managing unit 243 to check the features generated together in the same DP and then checks whether there is an interaction therebetween (308). In this case, the feature table 27 is referred to for processing according to the properties of the respective features. In the case where the two features simultaneously perform the write operation, the case where the generated feature performs the read operation, And the case of performing the operation is determined as an interaction. In the former case, the generated feature is skipped. In the latter case, the feature that occurred before the current feature is generated is reprocessed.

The checking process 308 of the co-occurring features in the occurrence feature checking unit 253 is also performed for the interaction between all the generated service features.

Finally, when the interaction process is completed for all the generated features (309), control is passed to the base call processing unit (21) again to continue the call processing (301).

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 implements the function of interaction management between service features referred to in the ITU-T in the intelligent network service exchange system so that the interaction management unit can determine whether or not the degree of access to resources of the intelligent network service characteristics , It is possible to perform the processing on the interaction based on this, and the processing algorithm for the interaction is made through simple data and the algorithm itself is simple, so that it is possible to perform real-time processing in the intelligent network service switching system . It also has the effect of being independent of adding new services.
