By stabilizing by waiting for the time of the loading process, the program stored in the allocated area of the loading memory 100 by the loading block task processor of the loading process is sequentially read from the upper by 1 key in the unit of byte block unit and applied to the communication unit 75 Transmitting to the base station 40 through the base station controller 30 (S130); The down process consists of a process of stabilizing (S140) by waiting for a predetermined time or delaying (DELAY) for a predetermined time so that the program transmitted in the step (S130) is normally downloaded to a plurality of base station controllers and the base station, and the processor unit of the down process ( 55) it is determined whether all transmissions of the corresponding program are completed to the plurality of base stations, and if the transmission is completed, the completion process (S150) proceeds to the end (S150), and the determination process in the completion process (S150) does not complete the program transmission. In this case, after downloading a byte block unit to the plurality of base stations 40 and sequentially transmitting the byte block unit by 1 key according to the next order of the program recorded in the loading memory 100, the feedback is returned to the down process (S130) (FEEDBACK). If the download transfer of the program is not completed, the loading block task processor Group consists of the down process iterations (S160) of transmitting the request byte blocks program key 1 by the following sequence of byte blocks are sequentially transmitted key 1 and fed back into the process at the down.

Hereinafter, an apparatus for downloading a program to a plurality of base station controllers and a base station in a wireless operation station constituting a mobile communication base station system, and an operation method thereof according to the present invention having the above configuration will be described in detail with reference to FIGS. 4 and 5. do.

The BSM 25 according to the present invention monitors, controls, and operates a base station system of a mobile communication system. The base station controller (BSC) receives a plurality of base station controllers (BSCs) for wireless transmission signals applied from the mobile switching center 10. 30 and a plurality of base stations (BS) 40, or at the same time by the control of the network management system 90 for intensively monitoring the operating state of the base station system, or by hardware reset of the base station system, circuit board It is necessary to download or load an operating program or an updated application program, etc. to a plurality of base stations by re-installation, reset by self-power, or the like.

The processor unit 55 of the wireless operating station 25 performs operations and applications from a network management system 90 connected to the matching unit 85 or a base station system connected to the communication unit 75. When there is a request for downloading a program file or a plurality of program files by table writing (S100), the processor unit 55 allocates and activates a loading block (DLMB) task processor, and the corresponding program (s) An area of a capacity that can be recorded and stored is assigned to the loading memory 100 and allocated (S110).

The loading memory 100 is made of a semiconductor, and the input / output speed is very fast, and the loading block task processor allocated by activation in the processor unit 55 searches for the database 65 and has a loading request. All the program (s) are read and recorded and stored in the allotted area of the loading memory 100 (S120).

The loading block task processor TASK PROCESSOR of the processor unit 55 sequentially reads the program (s) recorded in the loading memory 100 from the beginning in units of byte (K BYTE) blocks by 1 key to the communication unit 75. Since it is applied, the base station controller 30 and the base station 40 to transmit for download (S130), by the transmission of the process (S130) by a predetermined time so that the download is normally completed to all the base station 40 without error, Delay processing while waiting for a while, so that the program download is stabilized (S140).

In the safety process as described above (S140), for example, in the case of the IMT-2000 base station system, one radio operating station 25 controls 16 base station controllers 30, one base station controller 30 is 128 Since the number of base stations 40 are controlled, the number of base stations 40 to be transmitted and downloaded from one radio operating station 25 is 2,048 in total, depending on the transmission distance to the base station 40 or each base station 40. Due to the time required for the download process, a certain stabilization time is required for all base stations 40 until the program of the byte block unit capacity is normally downloaded without error.

If the stabilization time of the process (S140) is not given, a transmission error (ERROR) may occur due to a collision with data downloaded or loaded in the following order, and a program loading error occurs.

By the program download transmission in units of byte blocks by 1 key by the down process (S130, S140), it is determined whether all the corresponding programs requested to be transmitted in the request process (S100) have been transferred (S150), and the process (S150). If the program download transfer is completed, the process of ending the program loading is completed. When the program download transmission is not completed in the determination of the step S150, the download request of the byte block unit program is performed by 1 key by the next order of the byte block unit by the 1 key transmitted by the down process (S130, S140). A signal to be generated is generated by the loading block task processor of the processor unit 55, and the feedback is returned to the down process (S130) (S160), so that the download is repeated.

By the above-described repetition process (S160), all the programs stored in the loading memory 100 made of semiconductors are repeated until the transfer is completed, and the loading memory 100 made of semiconductors has a very high data input / output processing speed. In addition, the load of the processor unit 55 or the overhead OVERHEAD is not burdened, and the download or load time of the program is rapidly improved, thereby increasing the reliability of the base station system.

In one embodiment, when a program recorded in a database (DB) is downloaded to 2048 BSs according to the IMT-2000 method, there is a serious problem that takes about 9 hours. In the case of applying the technique to the present invention, the program can be downloaded to the 2048 base stations within two hours.

Therefore, when a new version (VERSION) program or software package is to be applied to the base station system, the subscriber's inconvenience is minimized by quickly downloading the mobile terminal's call connection number at the minimum time, such as at night. Can provide maximum service to subscriber.

According to the present invention having the above configuration, all the programs to be downloaded are stored using the semiconductor memory of the loading memory provided in the wireless operating station, and the sequential downloads are performed in byte blocks by 1 key to a plurality of base stations using the stored programs. There is an industrial advantage to minimize program download time and reduce load.

In addition, since the time to download the program to the base station system is reduced, the mobile communication service cannot be provided again quickly, thereby minimizing the inconvenience of the subscriber and the loss of business opportunity, and at the same time, the maximum service can be provided by the program that is quickly updated. As a result, it is convenient to use to improve the reliability of the system.
