The present invention relates to a method for loading a program in an exchange system, and more particularly, to a program loading method for each service type of a processor in an exchange system of an accumulated program control method.

Since the development of the accumulated program control system, a variety of services have been required from users. To meet these demands, developers continue to develop programs, and various service functions developed in this way are loaded and executed inside the exchange system. However, even though not all services of the developed exchange system are used in each processor, all the services are loaded and used in each processor. As a result, each processor loads unnecessary programs and thus does not operate efficiently.

Accordingly, an object of the present invention is to provide a program loading method for each service type of a processor for loading only a specific service function required for each processor among the functions of an accumulation program type exchange system.

The method according to the present invention comprises the steps of: initializing a loading block table including type information for various types of services provided by the exchange system upon restarting the exchange system; A second initialization step of initializing a loading table for each processor in which a block list to be loaded is stored for at least one or more processors included in the switching system; Linking the loading information stored in the loading block table initialized in the first initialization step and the loading table for each processor initialized in the second initialization step to process program loading information according to a service type provided for each processor; And selecting and loading only a necessary program for each processor based on the loading information processed in the processing step.

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

1 is a block diagram of an exchange system for performing a program loading method of a service type of a processor according to the present invention, wherein a magnetic tape unit equipped with a magnetic tape storing a special service program (hereinafter referred to as MTU (Magnetic Tape Unit)) D) 102, a disc 103 and an operating maintenance processor (hereinafter referred to as OMP (Operating Management Processor) 101), including a central control subsystem (hereinafter referred to as Central Control Subsystem (CCS), 100), many It consists of a matching exchange subsystem (hereinafter referred to as Access Switching Subsystem (AP), 111 ~ 113) of the matching exchange processor (hereinafter referred to as ASS (Access Switching Subsystem), 110), the operator terminal 130. In particular, the OMP 101 contains all information about the system startup and loader for program loading (hereinafter abbreviated as SSL (System Setup and Loader)), the processor loader (hereinafter abbreviated as Processor Loader) and the program to be loaded. It is configured to include an existing database operating system (hereinafter referred to as DBMS (Database Management System)).

2 is a flowchart illustrating a process of initializing a data structure for loading when performing a program loading method for each service type of a processor according to the present invention.

In more detail, upon restarting the switching system (or restarting function blocks (SSL, PL) for system loading in the OMP 101), the data on the message output to the terminal 130 in step 201 is described. Initializes the process and proceeds to step 202 to initialize the loading block table in the DBMS. In this case, the loading block table includes type information of a service stored in the disc 103. In step 203, a table (or loading block information data structure) storing a list of programs to be loaded for each distributed processor is initialized. In step 204, the processor table and the block table are linked using information on the type of service possessed by the exchange system obtained in the initialization process of step 202 and step 203 and the type of service required for each processor. (Link) By the linked data, the OMP 101 selects and transmits only the necessary programs by IPC (Inter Processor Communication) to each of the processors 111 to 113 provided in the matching exchange subsystem 130.

The loading information of a block (minimum unit for implementing a specific service) according to the system service type used here is defined when the first system program is produced, and the information of the defined block is stored on a disk in a database form. When the system is restarted, the information stored in the database state is connected to each other (by the link processing in the above-described step 204) to process the loading information of various kinds of distributed processors. That is, information about a program to be loaded is processed according to a service provided for each processor, and only the necessary programs for each processor are loaded using the processed loading information. The processed loading information may be searched as shown in FIG. 3 or modified as shown in FIG.

3 is a flowchart illustrating a data retrieval process when a program loading method for each service type of a processor according to the present invention is performed.

As shown in the flowchart of FIG. 3, when an operator authorizes an information retrieval command through the terminal 130 with respect to the program loading information stored in the DBMS in the OMP 101, the operator receives the information retrieval command in step 301 and proceeds to step 302. It proceeds and analyzes whether the information received through SSL is suitable for retrieving loading information. As a result of the analysis, if the authorized command is normal, the process proceeds to step 304 through step 303 to search the information database in the DBMS, proceeds to step 305, outputs the searched result, and then ends the search operation.

However, if the analysis result of the step 302, the authorized command is inappropriate to search, the process proceeds to step 306 through step 303, the OMP 101 outputs a command error result message and terminates the search operation. The output message is transmitted to the terminal 130 and displayed to be recognized by the operator.

4 is a flowchart illustrating a data change process when performing a program loading method according to the present invention.

As shown in FIG. 4, when the operator applies the information change command through the terminal 130 to change the data on the loading information stored in the DBMS, it is received in step 401 and proceeds to step 402.

In step 402, it is checked whether a service to be changed is changeable by the information requested to be changed. As a result of the check, if the service is changeable, the process proceeds to step 403 to change the database of the service in the DBMS in the OMP 101. In step 404, it is checked whether the change is normally performed. If the check result is normal, the process proceeds to step 405 and outputs a message indicating that the service type change result is normally performed through the terminal 103 and ends the change operation.

However, if the check result of step 402 is not a changeable service type or the check result of step 404 does not change normally, the process proceeds to step 406 and outputs a message indicating that the change is impossible or that the change result is abnormal and ends the change operation. do. The output message is displayed to be recognized by the operator through the terminal 130 as described above.

As described above, the present invention selects and loads only the programs required for each service type of the processor among various service programs accumulated in the exchange system, thereby preventing unnecessary malfunction of the processor and unnecessary unnecessary loading of the service function. Program loading also reduces the load on the processor.
