Abstract

PURPOSE: A method for performing an instruction in an intelligence network system is provided to prevent a service from being broken although new service is provided by connecting an SLP and SIB dynamically. CONSTITUTION: A service businessman edits a service to be appended in an SCE(service creation environment), and an icon-typed SLP(service logic program) is prepared(S110). At this time, the SLP calls an SIB(service independent building block). The SLP stored as an icon type in the SCE is converted into a source file(the C language)(S120). The service logic program converted into the C language is transmitted to a service control point, an intelligent peripheral and an SMS(system maintenance subsystem) through a network(S130). The SIB is compiled and converted into a shared object(S140). The SLP calls the SIB converted into a shared object without an additional initialization stage(S150). The SLP executes the called SIB, and appends new service(S160).

Description

Instruction method of intelligent network system {THE METHOD FOR OPERATING THE INSTRUCTION IN THE INTELLIGENT NETWORK}

The present invention relates to an instruction execution method, and more particularly, to an instruction execution method of an intelligent network system in which a communication service is not disconnected even when a new service is newly added in an intelligent network system.

Intelligent Network is a method that combines signals into one common line signaling method and configures voice and signaling system into separate communication networks. It installs a separate large computer and database on the existing communication network to concentrate the intelligent network service processing functions here. It is a high-level communication network that can efficiently implement and operate various communication services.

This intelligent network consists of public switched telephone network (PSTN) and integrated services digital network (ISDN) as the center of the hardware, and this structure has a software intelligent layer to provide flexible network management and new services. It is to facilitate the introduction of.

The intelligent layer is composed of software and a database using a computer, and the introduction of a new service is a form in which a service can be provided only by developing a software. In addition, since there is no modification of the call processing program of the existing telephone when introducing a new service, the influence of the existing exchange is minimized and it is easy to introduce and use a new service.

Moreover, the direct control of the service by the subscriber is possible, and the service area can be easily expanded.

Such an intelligent network system refers to equipment capable of generating and processing a service desired by a service provider. The network elements used in an intelligent network include a service switching point (hereinafter referred to as an SSP) and a service control device (Service Control). Point; hereinafter referred to as SCP), Intelligent Peripheral (hereinafter referred to as IP), Service Management Point (hereinafter referred to as SMP), and Service Creation Environment (hereinafter referred to as SMP) , Referred to as SCE).

The service development environment is a device for newly building a service desired by a telecommunication service provider. The service logic program (SLP) developed here is a plurality of service independent blocks (hereinafter referred to as SIBs). Is done.

The SLP is created in the SCE and delivered to SCP, IP, SMS, etc. through the network, and executed in the place where the SLP portion is dynamically managed, but the portion for the SIB is statically. This is managed because the SIB is not called dynamically and is managed statically because of its high throughput and low cost.

However, although it is true that the above-mentioned conventional instruction execution method, that is, calling SIB statically has some advantages, not only the types of services vary from day to day, but also the service in the recent communication service situation of upgrading. Disconnection is a fatal drawback that deteriorates the service provider's image.

Therefore, it is necessary to overcome the disadvantage that the communication service is interrupted by stopping the service whenever the intelligent network system tries to provide a new service.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a method of performing an instruction of an intelligent network system that does not interrupt a service even when a new service is provided by dynamically connecting both SLP and SIB.

A feature of the present invention for achieving the above object is a method of performing an instruction of an intelligent network system including a service switching device, a service control device, an intelligent peripheral device, a service management device, and a service development environment. Developing a service logic program in the form of an icon for upgrading new services and existing services; Converting the developed service into a C language; Delivering to the place where the service is to be executed; Compiling the service independent block and converting the service independent block into a shared object; Calling a service independent block converted into the shared object; It is to provide an instruction performing method of the intelligent network system comprising the step of executing the developed service logic program.

Hereinafter, a dynamic service logic performing method of an intelligent network network system according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a method of performing instructions of an intelligent network system according to the present invention.

As a first step (S110), a service provider edits a service to be added in a service creation environment (SCE) to create a service logic program in the form of an icon. In this case, the Service Logic Program (SLP) calls a plurality of Service Independent Building Blocks (SIBs) according to functions to perform a service designed by an operator.

As a second step (S120), the service logic program stored in the form of an icon in the service development environment is converted into a source file, that is, a C language.

As a third step (S130), the service logic program converted to C language is transferred to a service control point, an intelligent peripheral, a system maintenance subsystem, and the like through a network. At this time, the SMS is located in the CCS system management and loading control function, all processor status management and monitoring function, recovery and configuration change function according to the failure of the system, system time and holiday information management and error detection function processing and control function It manages the maintenance of the whole system.

As a fourth step S140, the service independent block is compiled and converted into a shared object.

As a fifth step (S150), the service logic program calls the service independent block converted into the shared object without going through a separate initialization step. At this time, the service independent block is called by the service logic program by a symbolic binding method in a service development environment.

As a sixth step S160, the service logic program adds a new service by executing the called service independent block.

The instruction format of the service logic program proceeding at this stage is shown in FIG.

As shown, the instruction used in the service logic program is divided into approximately four parts.

That is, the instruction of the service logic program transmits the information to the OP code 10 designating the service independent block, the option code 12 containing information selectable according to the OP code, and the corresponding service independent block. Or first to tenth registers 14a-14j for receiving or receiving an error, and an error handler 16 for performing error processing when an error occurs.

In summary, when a service provider develops a new service, the service independent block containing the contents is not bound at compile time, but is dynamically loaded through symbolic binding at execution time.

According to the instruction execution method of the intelligent network system as described above has the following advantages.

First, even if a service provider adds a new service in an intelligent network system, there is no need to stop the service.

Second, even if the service provider needs to upgrade the intelligent network system, it is unnecessary to disconnect the service. Therefore, system management is more efficient.
