In the third step (S130), the version (Version) of the operation program stored in the BSP 42 of the base station 40 is newly downloaded (Down Load) stored in the CCP 32 of the base station control unit 30 stored operation A case different from the version of the program will be described in detail. An operation program or file newly downloaded and stored in the CCP 32 of the base station controller 30 may be stored in the base station 40. Down load new to the BSP 42 (S170),

The base station 40 which has downloaded the operation program or the operation file from the base station controller 30 in a new version (Version) is the base station operating data or base station operating parameters required for base station operation directly from the base station management unit (BSM) 20 ( Parameter) to download (S180),

The downloaded operating program or file and parameters are stored in a flash memory which is a non-volatile memory of a base station main processor (BSP) 42 which is a main processor of the base station 40. Then, the process (S190) of separately managing the version (Version) of the operating program or file.

Hereinafter, the configuration as described above according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In order to load an operation program or an operation file for operating the base station 40 of the mobile communication system, an operation program stored in and stored in the base station manager 20 formed of a work station class computer. Or download the operating file (Down Load).

The operation program as described above is downloaded from the base station management unit 20 to the CCP 32 of the base station control unit 30 by the control of the central control and switching center 10, and again, the BSP which is a control unit of the base station 40. It is downloaded to 42.

In the process of downloading as described above, the base station manager 20 initializes and prepares to download (S110), and the base station manager 20 manages all 12 base station controllers 30 according to an embodiment. Download all programs and base station loading information file (Version) necessary for operation of base station controller system.

In other words, the base station controller 30 may load information (Version) of dcnos, btscapp, tfucapp, dcucapp, rfucapp, mcucapp required for the operation of the base station 40, including programs ccpos, ccpuser, and PLD required for its operation. It is also downloaded to the CCP (32) (S120).

The base station 40 loading information downloaded to the base station controller 30 is the same as the version (Version) of the management program already stored in the BSP 42 before being downloaded to the BSP 42 of the base station 40. It is determined whether or not the version (Version) (S130).

In the above process, if the version of the operation program already stored in the BSP 42 and the version of the operation program stored in the CCP 32 are the same, the base station controller again downloads the base station operating program from the base station manager. Since it does not need to be loaded, it does not receive a download, and directly downloads operation data or parameters of the base station 40 from the base station manager 20.

The base station 40 directly downloads the base station operating parameters from the base station manager 20, the base station manager 20 is a work station class computer, the input or modification of the operation program and operation data is This is because the base station controller 30 does not have an input or correction function as described above.

In addition, the plurality of base stations 40 have different channels and frequencies allocated by the installed location and the surrounding environment, and the output and hardware configurations, power consumption, size, etc., which are transmitted are different, respectively. Data or parameters are different for each base station.

As described above, each base station operating parameter or operation data cannot be determined and set in advance, and an appropriate base station 40 equipment should be installed according to the environmental requirements in which the base station 40 is installed. After the appropriate base station 40 is installed, the corresponding parameter is input from the base station manager 20 formed of the workstation class computer, and the parameter is directly downloaded by the base station 40.

In addition, the frequency and transmission output for each channel used in each base station 40 may need to be changed by the control and management of the central control and switching center 10, in which case, the base station manager 20 in the system operator It is manually input by the, and is downloaded directly between the base station management unit 20 and the base station 40 for the reason that it is downloaded and applied to the base station (40).

In the third step (S130), the version of the management program of the base station 40 stored in the CCP 32 of the base station control unit 30 and the version of the management program stored in the BSP 42 of the base station 40 If the (Version) is different, the base station controller receives the base station operation program from the base station manager (Down Load) (S170), and after downloading to the base station, the base station from the base station manager (BSM) 20, the base station operating parameters or operation After directly downloading the data (S180), the downloaded and downloaded operating program and operating parameters are stored in the flash memory, which is a non-volatile memory. The version is separately stored and managed (S190).

After the fourth process (S140) and the ninth process (S190), the central control and switching center 10 is initialized by the base station control unit 30 or the base station 40 due to failure or maintenance, etc. If it is initialized, and if it is initialized, it is fed back to the third process (S130) to repeat the above process in order, and if not initialized, the base station 40 is non-volatile (Non-Volatile) Normal operation is performed by the operating program and operating parameters stored in the flash memory (S160).

Therefore, when using the method of loading the base station operating program of the present invention as described above, it is time for the conventional base station 40 to download and store the operating program and operating parameters that have been upgraded to the most recent one. For example, in the case of the 800 MHz mobile communication system, the conventional 5 minutes to 10 minutes can be shortened to about 1/3 or less, thereby quickly normalizing the base station, improving the quality of service to the subscriber, Not only can the reliability of the mobile communication system be improved, but maintenance and repair of the base station controller 30 and the base station can be promptly performed by the maintenance personnel, and a quick recovery can be performed even in the event of a failure.

According to the present invention having the above configuration, when the base station controller and the base station are initialized by failure or maintenance, the version of the operating program and operating parameters stored in the flash memory of the base station is compared with the version of the base station program stored in the base station controller. In the same case, only the operating parameters are downloaded directly from the base station management unit, thereby reducing the loading time of the base station program and quickly normalizing the base station, thereby improving the quality of service to consumers, improving the reliability of the system, It enables rapid maintenance and has an industrial use effect in which a rapid recovery is performed even in the case of a failure.
