    {Method for corresponding with data among system in digital mobile radio communication network}
    The present invention relates to a method of data matching between a base station manager (BSM), a base station controller (BSC), and a base station transceiver subsystem (BTS) in a digital mobile radio communication network. In particular, it is possible to perform the function of loading the error detected relation and the periodic relation loading function by sending and receiving the data change request message between BSM, BSC, and BTS, so that each system does not stop the mobile communication service. The present invention relates to a method of data matching between systems in a digital mobile communication network for matching data between networks.
    In general, a communication system is divided into a plurality of subsystems to be operated and managed. For example, a digital mobile communication system includes a BTS for performing a wireless access function with a mobile station; A BSC managing the BTS; It is configured to include the BSC and the BSM for operation management and maintenance of the BTS, providing a mobile communication service to the subscriber. Since several systems provide mobile communication services by interworking with each other, each system needs essential common data to operate the entire mobile communication system. That is, BTS is Program Loading Data (PLD) to manage the operation of BTS, BSC is Operation Data (PLD) to manage the operation of BTS managed by BSC and BSC, BSM is operation of BSM and BSC and BTS Each has its own operational data (PLD) to manage it. The PLDs of BSMs, BSCs and BTSs each must be matched for smooth system operation.
    When another subscriber joins, or a device corresponding to a resource is mounted or detached, data on the same should be changed. When changing such data, all corresponding data of each system should be changed, so that each system should have matching data.
    When data is changed in order to have matched data between systems, the BSM 1 sends data changes to the BSC 2 and the BTS 3 to the BTS 3 so that the BTS 3 changes the data. After that, the data is changed in the order of BSC (2) and BSM (1). However, when data change is abnormally performed in the BSC (2) when performing data change between systems, the BSC (2) cannot receive PLD loading from the BTS (3). As a result, a data mismatch occurs between the BSM 1, the BSC 2, and the BTS 3. Thus, there is no reliability in system operation and management.
    In order to recover the data inconsistency between the systems, the BSC (2) should receive the entire PLD from the BSM (1) and the BTS (3) from the BSC (2). Since all functions related to the call service are stopped, there is a problem that the mobile communication service is stopped.
    Therefore, the present invention has been proposed to solve the conventional problems as described above, the object of the present invention is
    Data change request message between BSM, BSC, and BTS sends and receives the function of loading the error detected relation and periodic relation loading, so that the data between the systems cannot be interrupted without interrupting the mobile communication service. The present invention provides a method of data matching between systems in a digital mobile communication network.
    Another object of the present invention is to determine whether data is changed by sending and receiving a data change request message to each other, so that when inconsistent data is generated, the system loads the relation from the upper system or the lower system according to the occurrence time point. The present invention provides a method of data matching between systems in a digital mobile communication network.
    In order to achieve the above object, the data matching method between the systems of the digital mobile communication network according to the present invention,
    When a data change request is transmitted from the base station manager (BSM) of the digital mobile communication system to the control station (BSC), the BSC determines whether or not the data to be changed is matched, and when the data match is determined, the BSC requests a data change. A first step of transmitting the relation loading request to the BSM by the BSC, in case of data mismatch, to match the mismatched data;
    The BTS that receives the data change request from the BSC determines whether or not the data is requested to be changed, and if the data is inconsistent, the BTS requests loading of the relation to the BSC to match the data, and matches the data when the data is matched. Performing a second step of transmitting the result to the BSC;
    A third step in which the BSC requests data loading of the relation to the BTS to perform data change when the received data change result is a change failure or a change fails in data change in the BSC that receives the data change success result signal; Steps;
    When the data change of the BSC is successfully performed, the BSM performs a data change, and if the change fails, performing a fourth step of requesting loading of the relation to the BSC to successfully change the data change. It is done.
    In the method of determining whether or not the data is matched, if the system that has received the change request cannot access the change target data, it is determined that the change target data is inconsistent with the change target data and the change request data is determined. When the received system can access the change target data, it is determined that the change target data is matched between the system that has requested the change and the received system.
    The data matching method between the systems according to the present invention,
    Checking the list of relations to be loaded from the BSM to the BSC when it is time to execute periodic full relation loading, and loading the entire relation of the relation list into the BSC in relation units; When the loading of the relation from the BSM to the BSC is completed, the method further includes checking a list of relations to be loaded into the BTS from the BSC, and then loading the entire relation of the relation list into the BTS in relation units. .

    2 is a flowchart illustrating a method of matching upper system data of FIG. 1;
    3 is a flowchart showing a method of matching subsystem data of FIG. 1;
    4 is a flowchart showing a method of loading a periodic data relation loading in accordance with the present invention.
    Hereinafter, the data matching method between the respective systems of the present invention digital mobile communication network will be described in detail with reference to the accompanying drawings.
    In general, each PLD of BSM (1), BSC (2), and BTS (3) has a plurality of files, and each file has a plurality of relations. This relation is the most basic form of information storage in the relational database model. Thus, data change is performed in relation units. Conventional data matching methods between systems are performed in units of files when loading the entire PLD, but in the present invention, the units are loaded in units of relations.
    1 is a flowchart illustrating a method of interworking between systems when a data change request is requested from an operator among data matching methods between systems according to the present invention.
    As shown, when a data change request is input from the operator to the BSM 1, and a data change request is transmitted from the BSM 1 to the BSC 2, the BSC 2 checks whether or not the change requested data is matched. When the data is matched, the BSC 2 transmits a data change request to the BTS 3, and when the data is inconsistent, the BSC 2 transmits the corresponding relation loading request to the BSM 1 to match the inconsistent data. First step (ST11-ST15) to make; Receiving the data change request from the BSC (2), the BTS (3) determines whether or not the change requested data, and if the discrepancy of the data as a result of the determination, request the BSC (2) to load the corresponding relation to match the data, A second step (ST16-ST21) of performing data change function upon data matching and transmitting the result to the BSC 2; If the received data change result is a change failure or a change fails when data is changed in the BSC 2 that has received the data change success result signal, the BSC 2 requests loading of the relation to the BTS 3 and the data is changed. A third step ST24 for performing a change; A fourth step of performing data change in the BSM 1 when the data change of the BSC 2 is successfully performed, and requesting loading of the relation to the BSC 2 when the change fails, thereby successfully changing the data change (ST25). , ST26).
    The method of determining whether or not the data is matched is determined to be inconsistent with the upper system when the change target data requested to be changed from the upper system cannot be accessed, and when the data change function is performed by accessing the change target data, the upper system It is determined that the data match state with.
    2 shows a data matching method performed in the upper system BSM 1 or BSC 2.
    As shown, the message received from the subsystem is examined to perform relation loading to the subsystem if the received message is not an acknowledgment (ACK), and to perform data change if the received message is a success response message. Steps ST31-ST34; As a result of performing the data change, requesting the relation system to load a relation if the data change is not successfully performed (ST35, ST36); As a result of the data change, if the data change is successfully performed, the process outputs a result to the operator or transmits a success response message to the upper system (ST35, ST37).
    If the system performing the data matching method is BSC 2, the subsystem is BTS 3, and if the system performing the data matching method is BSM 1, the subsystem is BSC 2;
    And a data matching method performed in the BSC 2 or the BTS 3, which is a subsystem, is shown in FIG.
    As shown in the drawing, the message received from the upper system is inspected, and if the received message is a data change request message, it is determined whether the data is matched. If the determination result data is inconsistent, a failure response message (NACK) is transmitted to the upper system. Performing the requested data change function when the determination result data is in a coincidence state (ST41-ST47); If the data change function has not been successfully performed, transmitting a failure response message (NACK) to the upper system; if the data change function has been successfully performed, transmitting a success response message (ACK) to the upper system (ST48). , ST49); If the received message is a relation loading request message as a result of checking the received message from the upper system, steps (ST42 and ST50) of performing relation loading on the upper system are performed.
    If the system performing the data matching method is BTS 3, the upper system is BSC 2, and if the system performing the data matching method is BSC 2, the upper system is BSM 1;
    The method of determining whether or not the data is matched is determined to be a data inconsistency with the upper system when the data to be changed from the upper system cannot be accessed, and when the data change function can be performed by accessing the requested data, the upper system and the upper system. It is determined that the data match.
    Referring to the data matching method through the relation loading between each system according to the present invention as follows.
    When a data change request is input to the BSM 1 from the operator, the BSM 1 transmits a data change request to the BSC 2 (ST11). At this time, data change is performed in relation units. Accordingly, the BSC 2 determines whether or not the change is requested for data (ST12). At this time, if the BSC 2 cannot access the requested data, the BSC 2 determines that the data is inconsistent with the BSM 1, and the BSC 2 approaches the requested data. When not possible, the BSC 2 determines that the data is inconsistent with the BSM 1. Therefore, when there is a data mismatch, the BSC 2 requests the BSM 1 to load the relation (ST13). The BSM 1 loads the relation so that the BSM 1 and the BSC 2 coincide with each other (ST14, ST15). As described above, the data matching method according to the present invention makes the matching state by receiving the relation when the error of the relation is detected.
    When the relation requested to be changed is mutually matched between the BSM 1 and the BSC 2, the BSC 2 sends a data change request to the BTS 3 (ST16), whereby the BTS 3 requests the change. It is determined whether or not the BTS 3 and the BSC 2 match with the received data (ST17). As a result of the determination, when the data does not match, the corresponding relation loading is requested to the BSC 2 (ST18). The BSC 2 then loads the requested relation to the BTS 3 (ST 19), and the BTS 3 sends a relation loading completion message to the BSC 2 (ST 20) to match the requested relation to the change. Thus, the BTS 3 makes a change and transmits the result to the BSC 2 (ST21).
    If the result of the change is unsuccessful, the BSC 2 performs relation loading into the BTS 3. If the data change result is successful, the BSC 2 performs data change. If the data change fails, the BSC 2 requests a relation loading to the BTS 3 (ST22). The BTS 3 thus starts loading the requested relation into the BSC 2 (ST23). When the loading is completed, the BSC 2 transmits a loading completion message to the BTS 3. When the data change of the BSC 2 is completed in this manner and a success response message is transmitted to the BSM 1 (ST25), the BSM 1 performs data change (ST26). As described above, in the method of data matching between systems according to the present invention, a recovery operation for matching is performed on an error detected relation. In addition, by loading relations from the lower system to the upper system, that is, loading the relations from the BTS (3) to the BSC (2) or from the BSC (2) to the BSM (3), the loading of the mismatched relation is performed immediately. Reduce the incidence of data inconsistency
    Since the operation of each system illustrated in FIGS. 2 and 3 overlaps with the above-described operation, description thereof will be omitted.
    Next, a method of periodically performing relation loading for data matching between systems without interrupting a call processing function for providing a digital mobile communication service is shown in FIG. 4.
    As shown, when it is time to perform periodic full relation loading, the list of relations to be loaded from the BSM 1 to the BSC 2 is checked, and then the entire relation of the relation list is transferred to the BSC 2 in relation units. Loading (ST51-ST55); When the relation loading is completed from the BSM (1) to the BSC (2), after checking the list of relations to be loaded from the BSC (2) to the BTS (3), the entire relation of the relation list is loaded into the BTS (3) in relation units. Perform steps ST56-ST60.
    In order to implement this periodic relation loading method, the BSM 1 checks whether it is time to perform periodic full relation loading. Thus, when the execution time comes, the BSM 1 checks the list of relations to be loaded into the BSC 2 for the entire relation loading (ST51). After confirming the name and location of the relation, the relation begins to be loaded into the BSC 2 (ST52). When the result of this relation loading is sent from the BSC 2 to the BSM 1, the BSM 1 loads the next relation into the BSC 2. In this way, when the entire relation of the relation list is loaded in the BSC (ST53-ST55), the BSC (2) checks the list of relations to be loaded into the BTS (3) (ST56), and then in the BSM (1) the BSC ( The BTS 3 is loaded in a relation unit in the same manner as the 2) (ST57-ST60). The loading of the relation unit is performed with a specific period at the feature time set by the operator, and this specific period is set by the operator. By loading the PLD of each system in a relation unit as described above, an operation for matching the entire PLD between BSMs, BSCs, and BTSs can be performed without interrupting call processing for mobile communication services.
    As described above, in the method of data matching between systems of the digital mobile communication network according to the present invention, when a mismatch of relations between systems is detected due to transmission and reception of a data change request message between BSMs, BSCs, and BTSs, the BSM to the BSC is conventionally used. The data can only be loaded from BSC to BTS and from BTS to BSC, but from BSC to BTS, the present invention can load data from BTS to BSC and from BSC to BSM. The probability of data inconsistency is reduced. By periodically loading the PLD of each system in relation units, the call processing function for the mobile communication service is continuously performed without interruption, and the call processing function for the mobile communication service is continuously performed without interruption. Improve the reliability of.
