Along with the increase in demand for mobile phones, the BTS is required to add / change functions. To meet this demand, the BTS uses a file download function such as a program from a mobile communication maintenance monitoring console (hereinafter referred to as OMC). The function addition / change is realized. That is, as shown in FIG. 8, the BTSs 100 to 10N that are logically directly connected to the OMC 200 are configured to download a file for operation from the OMC 200. FIG. 9 is a diagram schematically showing the configuration of FIG. 8 and shows a state in which BTSs # 0 to # 11 are logically connected to the OMC.

  In the file download method in the mobile communication network system as described above, version management is important. That is, in a plurality of BTSs, various versions of programs and the like may exist depending on the installation time, operating environment, and the like. Therefore, when downloading a file such as a new program, it is necessary to check the version appropriately.

  An example of a program download method for checking such a version is disclosed in Patent Document 1. This download method consists of a central station that holds a program, a plurality of base stations that are connected to the central station via a communication line, hold a program downloaded from the central station, and perform processing based on this program, When the version of the program held by the central station is different from the version of the program held by the base station, the program held by the central station is downloaded to the base station. The base station inquires the version data of the program at a predetermined time to the central station, the version check processing means for comparing the version data held in the central station with the version data held in the base station, and the version data Download control processing means for sending a program download request to the central office when they do not match.

  Patent Document 2 discloses a radio base station program download method that does not require special equipment and can easily update a number of radio base station programs in a short time. In this scheme, the private branch exchange sequentially connects the management radio base stations to radio base stations whose programs have not been updated. The management radio base station transmits a new program stored in the radio base station. The radio base station updates its own program with the received program. Also, the private branch exchange uses the radio base station whose program has been rewritten as the master CS, and downloads the program from the master CS to an unupdated radio base station, thereby completing the download to all radio base stations in a short time. It is.

  Next, a communication sequence of the mobile communication network system configured as described above will be described. FIG. 5 is a flowchart showing a communication sequence among OMC, BTS and S-BTS according to the first embodiment of the present invention. In FIG. 5, BTS # 0 connected to OMC connects S-BTS # 0 and S-BTS # 1 under the control of BTS # 0 and downloads the program. In FIG. 5, BTS # 0 and S-BTS # 1 store the same new program as the downloaded program, and S-BTS # 0 stores an old program different from the downloaded program. Assuming that

  First, in steps S10, S12, and S15, BTS # 0, S-BTS # 0, and S-BTS # 1, respectively, are turned on when BTS # 0, S-BTS # 0, and S- Each program is activated by a program stored in BTS # 1 (steps S11, S13, S16). Since BTS # 0 and S-BTS # 1 store the new program, they start with the new program, and since S-BTS # 0 stores the old program, it starts with the old program. .

  The activated S-BTS # 0 and S-BTS # 1 respectively transmit a version report of the program used for activation to BTS # 0 (steps S14 and S17). In addition, the activated BTS # 0 receives version reports from the S-BTS # 0 and S-BTS # 1, confirms the version of the program used to activate the BTS # 0 itself, and sends the BTS to the OMC. The version of the program used for starting each of # 0, S-BTS # 0, and S-BTS # 1 is reported (step S18).

  The OMC that has received the version report transmitted from BTS # 0 compares the version of the program reported from BTS # 0 with the version report of the BTS stored in the OMC (step S19). It is assumed that the OMC stores the new BTS program in the OMC and recognizes that the BTS should be started with the new program.

  If the versions match as a result of version comparison, the OMC notifies BTS # 0 to that effect (step S20. However, in the example of FIG. 5, the version of S-BTS # 0 is different, so step S20). Will not go on). BTS # 0 starts the service (step S21). Further, BTS # 0 transmits a start permission signal (not shown) to S-BTS # 0 and S-BTS # 1, and S-BTS # 0 and S-BTS # 1 start service.

  If the versions do not match as a result of the version comparison (in the example of FIG. 5, the version of S-BTS # 0 is different), the OMC transmits a download start signal to BTS # 0 (step S22). . The BTS # 0 that has received the download start signal transmits a download start response to the OMC (step S23).

  The OMC that has received the download start response from the BTS executes a program download for the BTS # 0 (step S24). The BTS # 0 receives the program downloaded from the OMC and stores it in the BTS # 0. When the program transfer is completed, the BTS # 0 transmits a program download completion report to the OMC (step S25).

  Thereafter, the BTS # 0 downloads the program received from the OMC to the S-BTS # 0 (step S26) and downloads it to the S-BTS # 1 (step S27). The BTS # 0 performs a version comparison between the program downloaded from the OMC and the currently stored program stored in the BTS # 0 (step S28). As a result, since the version of the program downloaded from the OMC matches the version of the currently activated program, the program downloaded from the OMC is discarded (step S29), and the service operation is started (step S30).

  The S-BTS # 1 performs a version comparison between the program downloaded from the OMC via the BTS # 0 and the currently stored program stored in the S-BTS # 1 (step S35). As a result, since the version of the program downloaded from the OMC via the BTS # 0 matches the version of the currently running program, the program downloaded from the OMC via the BTS # 0 is discarded (step S36). Is started (step S37).

  On the other hand, the S-BTS # 0 performs a version comparison between the program downloaded from the OMC via the BTS # 0 and the program stored in the S-BTS # 0 and currently activated (step S31). As a result, there is a discrepancy between the version of the program downloaded from the OMC via BTS # 0 and the currently running program. Therefore, the program downloaded from the OMC via BTS # 0 is stored in a memory (F-ROM or the like) in S-BTS # 0 that does not disappear even if a system reset is executed. Further, the S-BTS # 0 is restarted by a system reset (steps S32 and S33), and the service operation is started with the new program downloaded from the OMC via the BTS # 0 (step S34).

  As described above, the BTS in the first embodiment may download the program downloaded from the OMC to the S-BTS without holding the version of the S-BTS program. The S-BTS determines whether the downloaded program is the latest and needs to be upgraded or discarded, and is either a new program that has been downloaded or a program that is currently running and stored. To start the service.

  FIG. 6 is a block diagram showing the configuration of the mobile communication network system according to the second embodiment of the present invention. FIG. 6 shows an example of a configuration in which the mobile communication network system includes one radio base station (BTS) 10a, a child radio base station (S-BTS) 20a, and one mobile communication maintenance monitoring console (OMC) 30. In FIG. 6, the same reference numerals as those in FIG. 4 represent the same or equivalent components, and the description thereof is omitted.

  In the BTS 10a, the version comparison unit 42a is different from the version comparison unit 42 of FIG. The version comparison unit 42a compares the versions of the program held in advance in the file holding unit 43 and the program downloaded from the OMC 30, and holds the version of the program of the S-BTS 20a reported from the S-BTS 20a. The function to compare with the version of the program downloaded from is added.

  On the other hand, in the S-BTS 20a, the version comparison unit 52 of FIG. 4 is omitted.

  Next, a communication sequence of the mobile communication network system configured as described above will be described. FIG. 7 is a flowchart showing a communication sequence between OMC, BTS and S-BTS according to the second embodiment of the present invention. In FIG. 7, some functions of BTS # 0, S-BTS # 0, and S-BTS # 1 are different from the functions shown in FIG. In FIG. 7, steps up to step S25 excluding step S18a are the same as those in FIG. However, when the BTS # 0 reports to the OMC the version of the program used to activate BTS # 0, S-BTS # 0, and S-BTS # 1 as a version report in step S18a, the S- The contents of the version report reported from BTS # 0 and S-BTS # 1 are held in BTS # 0.

  BTS # 0 transmits a program download completion report to the OMC (step S25), and then compares the version of the program received from the OMC with the currently activated program stored in BTS # 0. In addition, the program received from the OMC is compared with the versions of the S-BTS # 0 and S-BTS # 1 programs, which are the contents of the version report held in BTS # 0 in step S18a (step S28a).

  If the result of comparison in step S28a is the same (in the case of BTS # 0), BTS # 0 discards the program downloaded from the OMC (step S29) and starts service operation (step S30). If they do not match (they do not match because they match in the example of FIG. 7), the program downloaded from the OMC is retained, the system is restarted, and the service is updated with the new program downloaded from the OMC. Start operation.

  If BTS # 0 matches as a result of the comparison in step S28a (in the case of S-BTS # 1), the program downloaded from OMC is not downloaded to S-BTS # 1, and the activation permission signal Is transmitted (step S27a). The S-BTS # 1 that has received the activation permission signal starts operation of the service (step S37).

  Further, if the result of the comparison in step S28a is a mismatch (in the case of S-BTS # 0), BTS # 0 transfers the program downloaded from the OMC to S-BTS # 0 (step S26a). The S-BTS # 0 that has received the program does not need to perform version comparison with the program that is stored in the S-BTS # 0 and is currently running, and retains the program downloaded from the OMC and performs a system reset ( In step S32), the system is restarted by the new program downloaded from the OMC (step S33), and the service operation is started (step S34).

  As described above, the BTS in the second embodiment holds the version of the S-BTS program and compares it with the version of the program downloaded from the OMC. The program is downloaded, and an activation permission signal is sent to the S-BTS that does not need to be upgraded. Therefore, the S-BTS may start the service operation by either the downloaded new program or the stored and currently activated program depending on whether it is a downloaded program or an activation permission signal.
