Abstract

PURPOSE: A method for loading an operation program of a base station is provided to reduce a service-suspend time generated when a new program is loaded on a base station in a mobile communication system, and to load the new program into a not-used area of a memory in a call control processor(CCP), so that service of the base station can not be suspended through role changes of a waiting area and an operation area at a loading completion point. CONSTITUTION: An operation program generated from a BSM is loaded into a not-used area of a memory in a call control processor(CCP). The loaded operation program is delivered to a low layer processor. The low layer processor performs to verify the operation program. If a new program is verified, a normal operation is performed through the operation program of the not-used area of the memory and an operation program of a used area of the memory is suspended.

Description

Loading method operating program of base-station in moving communication system

The present invention relates to a method of loading an operating program of each base station for supporting a mobile communication service in the formation of a mobile communication service network. In particular, a new program is loaded on a standby area while a base station is operated by a conventional operating program and the loading is completed. The present invention relates to a method of loading an operating program of a base station in a mobile communication system such that there is no point of interruption of service operation of a base station by changing roles of a dash area and an operation area at a time point.

In general, as the number of mobile subscribers exploded, subscribers hoped for more value added services and higher call quality. Therefore, the mobile communication service provider also responds to the needs of subscribers and is constantly revising and supplementing the operating program. When generating an operation program, a lot of ways to load it from the base station and use it as a new operation program have been considered.

The hierarchical structure of the system for performing the above-described program loading operation up to now has a hierarchical tree structure, as shown in FIG. 1, wherein the BSM is responsible for loading the ACP and the Call Control Processor (CCP). The CCP is responsible for loading SIP and BCP, the BCP is responsible for CCC, and the SIP is responsible for loading SVP.

Accordingly, when the new program is applied, as shown in the accompanying FIG. 1, the new program is loaded into the CCP in the BSM, and then sequentially loaded in the subsystem.

In order to load a new program into the BCP, the CCP is loaded from the BSM and then loaded into the base station. At this time, there is a problem that the service is not provided until the new program is loaded into the CCP and the corresponding base station is restarted and the loading is completed.

In addition, when a bug occurs in the program after completing the loading of a new program, when the program is restored, the CCP completes the loading from the BSM, and the base station does not have a service during the loading time. Happens.

In addition, every time the base station program is verified, a problem arises in that the CCP is restarted and then loaded into the base station.

An object of the present invention for solving the above problems is to minimize the downtime of the service generated when loading new programs into the base station in the mobile communication system, and to increase the reliability of the system in the memory of the CCP during base station loading in order to increase the reliability of the system. To provide a method for loading an operating program of a base station in a mobile communication system in which a new program is loaded in a location not loaded by a program and there is no interruption of service operation of the base station by changing the role of a dash area and an operation area at the completion of loading. have.

2 is an exemplary operation diagram illustrating a method for loading an operating program of a base station in a mobile communication system according to the present invention.

A feature of the present invention for achieving the above object is a method of loading an operating program of a base station in a mobile communication system, wherein the lower layer processors are configured to receive sequential program downloads hierarchically from a BSM. A first process of loading an operating program generated from the BSM into an unused memory area inside a control processor, a second process of transferring the loaded operating program through the first process to a lower layer processor, and the second process A third process of executing the corresponding program in the processor that has received the operating program from the call control processor through the third process; and if the new operating program is verified through the third process, stored in the unused memory portion of the call control processor. Normal operation program It lies in a fourth step of performing the operation and stop the operating program in the memory area that was used in the past.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

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

2 is an exemplary operation diagram illustrating a method of loading an operating program of a base station in a mobile communication system according to the present invention.

First, the currently running program is marked as OLD and named as OLD program. Also, the program to be newly loaded is marked NEW and named NEW program.

If both processors of the CCP and the BCP are normal in step S10, the NEW program generated in the BSM of FIG. 1 attached to the CCP is loaded through the OLD program operating in the CCP operating area or the processor in the operating area and provided to the CCP. The memory area is loaded in the unused memory area.

At this time, after completion of the processor loading on the operation area by receiving a dual copy of the processor on the CCP standby area, the operation area and the standby area has the old software and the new software of the BCP.

Then, in step S11, the processor on the operation area of the CCP starts loading a new program of the BCP to the processor on the BCP waiting area. At this time, the role of the user is loaded by restarting the processor on the BCP waiting area.

After the above-described operation of step S11 is performed, the processor on the BCP standby region is newly moved to the operation region, so that the processor on the original operation region is transferred to the standby region. This series of steps is indicated by S12 in the accompanying FIG.

Step S13 is performed when it is determined that the test of the new software is satisfied in the BCP processor belonging to the newly operating area. However, if a new program is loaded from the CCP in the standby area, and there is a loading request from another base station, the loader of the CCP loads the old software of the BCP.

After the above-described series of operations are completed, in the process of step S14, the data on the standby area is loaded for the operation areas of all the BCPs. In step S15, when the loading of the data on the standby area is completed through the process of step S14, the CCP is completed. Copy the new program of the processor on the operation area to the old area and delete the new program.

The data is then matched by receiving dual copies from the standby area.

While the invention has been shown and described in connection with specific embodiments thereof, it will be appreciated that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone who owns it can easily find out.

In the mobile communication system according to the present invention operating as described above, by providing a method for loading an operating program of a base station, when loading a program related to the operation of a new base station that has not been verified, the CCP is restarted and then the CCP is not loaded into the base station. The new program to be loaded is loaded from the BSM, and the program can be verified using the standby portion of the base station. At this time, the operation portion performs normal operation and the standby portion alone performs the new program as the standby portion. By restarting and loading a new program from the CCP, there is no interruption of the operation.
