The present invention relates to a technology for providing an efficient and reliable scalable intelligent network service by defining mobile agents to provide.

1 is a diagram illustrating a general intelligent network structure, wherein an intelligent network includes a service switching point (SSP) 2 for switching a call generated from an intelligent network service user 1;

A common line signal network (CCS7) 3 for conveying service control information transmitted from the service switching system 2;

A service control system (SCP) (4) connected to the common line signal network (3) to perform a function of controlling a service call in a network dimension;

An intelligent information providing system (IP: Intelligent Peripheral) 5;

A service management system (SMS) 6 connected to the service control system 4 for managing service data;

Intelligent Network Application Protocol (INAP) on No.7 Common Line Signaling Network (3) is used for signal transmission between the service control system (4), service exchange system (2), and intelligent information providing system (5). I use it.

In the conventional intelligent network structure configured as described above, a service is generated through a service creation environment (SCE) service 7 and introduced and managed by the service management system 6.

The service control logic is located in the centralized service control system 4 and controls the service switching system 2 via the common line signaling network 3. That is, when an intelligent network call is generated, the service switching system 2 detects it and sends a call processing request query to the intelligent network control system through the common line signaling network 3, and proceeds with the call according to the service logic in the intelligent network control system.

However, as the intelligent network environment such as mobile network and internet network becomes complicated, and various intelligent network based service requests are derived from users such as multi-party communication and multimedia service under such network environment, the control method by the existing No.7 common line signaling method This alone has made it difficult to meet these demands.

In addition, as the use of intelligent network service increases, the usage of signal network and service control system increases, so bottlenecks due to signal traffic are predicted, and global ripple effect is predicted in case of service control system failure.

Agent technology is a concept derived from a computing network. Agent is defined as a software element that voluntarily performs a specific task on behalf of a user. This is a client / server technology in a conventional distributed processing environment. It is an advanced concept.

FIG. 2A is a block diagram illustrating service provision according to a conventional client / server concept, and FIG. 2B is a block diagram illustrating service provision according to a new mobile agent concept to which the present invention is applied. In FIG. While the client 10 and the server 11, which are static agents, perform specific tasks by communicating on a distributed processing environment (DPE) 12, a mobile agent technology as shown in FIG. A system located at a remote location by creating a mobile agent 14 to perform a particular task and moving the mobile agent 13 to a remote server to perform a task through a distributed agent environment (DAE) 14. Allows you to perform specific tasks using local information in.

This mobile agent technology enables the efficient use of network resources by moving programs rather than data. Once created, the agent can provide services by moving without user intervention using its intelligence, mobility, and autonomous.

In addition, the agent's ability to learn can voluntarily adapt to changes in the environment and provide services tailored to the needs of the user. Whereas existing client / server technologies have limited scalability due to centralized service provision, agent technologies that can provide local services as they move around the network can provide flexible services.

Distributed mobile agents in each of the intelligent network elements service management system 6, service control system 4, service exchange system 2, intelligent information processing system 5 and service generation environment means 7 and subscriber station 25, respectively.

A service agent 132 including intelligent network service logic and data provided;

A trigger agent 133 for triggering a service agent in the service exchange system;

It is divided into an adaptation agent 134 for interfacing with an existing intelligent network protocol.

In this structure, the intelligent network service logic is implemented as service agents 132 in the service creation and supply agencies 19 and 23, and these mobile service agents 131 to 134 are service control agencies 20 or The service is provided by moving to the service exchange agency 21.

Looking at the intelligent network service providing method through Figure 5 showing the service providing method according to the present invention in detail as follows.

Intelligent network services are generated as service agents in the service creation agency 23 and move to the service supply agency 19 (S1).

When the user who wants to receive the intelligent network service requests the service through the web, the supply agent in the service management system 6 transmits the corresponding service agent to the subscriber agency (S2).

The user inputs user specific information to the transmitted service agent, completes the service configuration, and retransmits the service to the service management system 6 (S3).

The supply agent in the service management system 6 checks the validity and security of the configuration information for the service agent and analyzes the characteristics of the service to determine the optimal location of the service agent (S4).

Subsequently, the supply agent moves the service agent to the service control agency 20, the outgoing service exchange agency 21, or the incoming service exchange agency according to the determined optimal location, and, if necessary, to the intelligent information processing agency 20 (S5). ).

The moved service agent provides the intelligent network service by adapting the existing intelligent network protocol by the adaptation agent 134 (S6).

At this time, the optimal location of the service agent in the step S4 is determined to be the closest to the service control location according to the characteristics of the service to minimize the operation of the signaling protocol. In other words, services such as call transfer and incoming call restriction, which are serviced at the called party exchange, are serviced by the incoming service exchange agency, speed dialing, and outgoing call restrictions, which are implemented by the calling party. For services that require centralized intelligent network control, such as telephone voting, the service control agency is determined to be the optimal location of the service agent.

The determined location of each service agent may be changed according to the learning capability of the mobile agent during service execution. That is, if it is determined that a service trigger is frequently generated by a specific service exchange system 2 during service provision, the service agent that has been performed by moving to the service control agency 20 moves to an agency within the service exchange system to perform a service. By reducing the operation of the signaling protocol by providing a service, to provide a service quickly.

6 shows a processing procedure of a service agent moved to a service exchange agency by a supply agent according to the present invention.

The service agents 132 moved to the service exchange agency 21 connect with the trigger agent 133 and deliver necessary trigger information. When a call arrives at the service exchange system 2 and reaches the sensing point 27 during processing by the call control device 26, the call processing is stopped and connected to the trigger agent 133 via the adaptive agent 134. The trigger agent 133 accesses a service agent (out of 1 to n) associated with the event that has occurred and performs service logic held by the service agent. The service agent notifies the call control device 26 in the exchange via the trigger agent 133 and the adaptive agent 134 of the execution result, and call processing resumes.

For example, the procedure for providing an incoming call restriction service that can be selectively received for a call coming to a specific subscriber is as follows. The incoming call restriction service agent generated by the service generation agency moves to the service supply agency and waits.

The user who wants to subscribe to the incoming call restriction service requests the incoming call restriction service to the supply agency through the subscriber agency in the subscriber station, and the supply agent sends the incoming call restriction service agent to the subscriber agency.

Then, the user configures the service agent to input the user specific information about the incoming call restriction service, for example, the call restriction conditions by date, region, and originator. The configured incoming call restriction service agent is moved back to the supply agency, which checks the validity, security, etc. of the information configured by the user and then starts the service by moving the incoming call restriction service agent to the subscriber's called party's service exchange agency. .

When any caller calls the subscriber, the call control device in the subscriber's incoming switching system detects the intelligent network call, stops the call processing and triggers the call to the service switching agency. The triggered call is connected to the triggering agent through an adaptation agent in the service switching agency and connected to the incoming call restriction service agent by the triggering agent. The service agent performs the incoming call restriction function on the triggered call and informs the call control function of the result through the adaptive agent. The call control function resumes interrupted call processing.

As described in detail above, the distributed mobile agent environment-based intelligent network structure can provide subscriber-specific services quickly through dynamic generation and configuration of service agents, and utilizes the agent's learning and mobility functions. Therefore, by introducing service agents as close to the service user as possible, there is an advantage of improving service performance and reliability, and by decentralizing service functions, the overall signal traffic is reduced and the dependency of the intelligent network control system is reduced.

In addition, the introduction of a data network-based distributed processing environment is accompanied by the advantages of providing intelligent network service and intelligent network-internet interworking service in the data network.

In addition, preferred embodiments of the present invention are disclosed for the purpose of illustration, those skilled in the art will be able to various modifications, changes, additions, etc. within the spirit and scope of the present invention, such modifications and modifications belong to the following claims You will have to look.
