Detailed ways

The present invention will be described in detail below with reference to the drawings and specific embodiments.

The method for automatically synchronizing the storage versions of the main and standby boards in the present invention refers to that after the standby board starts up normally, the main board learns whether the storage versions of the current main board and the standby board are consistent by querying the storage versions of the standby board. If they are not consistent, the version of the main board is transmitted to the standby board, so as to ensure the consistency of the storage versions of the main board and the standby board.

As shown in Figure 1, it is a schematic flow chart of an embodiment of the method for automatically synchronizing storage versions of the main and standby boards of the communication system of the present invention, including the following steps:

Step 101, after the standby board is powered on, first check that various resources on the standby board (including memory, system database, communication link of the main board and the standby board, etc.) are in an available state, and if everything is normal, then send a ready message to the main board . Sending this message indicates that all resources of the standby board are available. The version automatic synchronization request initiated by the main board can be accepted at any time;

Step 102, after receiving the ready message, the main board sends a storage version query message to the standby board and receives a query response message returned by the standby board, the response message includes the storage version information of the standby board;

Step 103, the main board compares whether the storage versions on the two boards are consistent, if not, then go to step 104; if consistent, the process ends;

Step 104, if inconsistent and the storage version of the main board is in a normal state, the main board sends an automatic synchronization request to the standby board file by file, the file includes but not limited to the version file of the controlled board stored on the main board, and can also include the version file related to the version file related information documents or other documents;

Step 105, after receiving the automatic synchronization request from the main board, the backup board obtains the corresponding version files from the main board through FTP (File Transfer Protocol) or other transmission methods until the synchronization of all version files is completed.

In the above-mentioned automatic synchronization process of the storage versions of the active and standby boards, if the automatic synchronization fails, a synchronization failure flag is set on the standby board. Because the storage version of the standby board is already in an abnormal state at this time, if this board becomes the main board, as the initiator of synchronization, it may destroy a board with a normal storage version, so the synchronization failure flag is set to indicate that the The stored version of the board is in an abnormal state. When the board whose synchronization failure flag is set is used as the main board, automatic synchronization will not occur.

In the above-mentioned automatic synchronization process of the storage versions of the main and standby boards, once the automatic synchronization starts, the storage version on the main and standby boards is not allowed to change, and the changes may include version addition, version deletion, version download, activation, deactivation, etc. Otherwise, even if it is done automatically, it cannot guarantee that the active and standby boards of the main control board are completely consistent. Therefore, when automatic synchronization is in progress, it is necessary to prohibit all other operations that may cause the storage version of the master and slave boards to change.

In the automatic synchronization process of the storage version of the main and standby boards mentioned above, the place where the automatic synchronization is applied includes but is not limited to the main control board, and all single boards with storage versions and active and standby configurations can be applied.

Below in conjunction with accompanying drawing 2, through the flow chart of the application embodiment of the automatic synchronization of the active and standby versions of the CCM single board of the CDMA mobile communication system, the specific implementation manner of the present invention will be described.

According to the structure of the system, CDMA mobile communication can be divided into the following modules: BSC (BaseStation Controller, base station controller) subsystem, BDS (Baseband Digital Subsystem, baseband) subsystem, RFS (Radio Frequency Systems, radio frequency) subsystem. Among them, OMP (Operation & Maintenance Processor, operation and maintenance processor) single board (BSC subsystem main control single board), CCM (Communication Control Module, communication control module) single board (BDS subsystem main control single board), RMM (read -only memory, read-only memory) single board (RFS subsystem main control single board) stores the storage version of its own single board and controlled single board. And there are standby boards, it is necessary to ensure that the storage versions of the main board and the standby board are completely consistent.

The automatic synchronization of the main and standby versions of the CCM single board of the CDMA mobile communication system includes the following steps:

Step 201, when the standby board of the CCM is powered on, first check whether there are memory resources required for initiating automatic synchronization, whether the database resources required for message sending and receiving are available, and whether the communication between the main board and the standby board is normal. Send a ready message. Wait for the main board to send the version automatic synchronization request message;

Step 202, after receiving the ready message from the standby board, the CCM main board sends a storage version query message to the standby board, and receives a query response message returned by the standby board, and the response message includes the storage version information of the standby board;

Step 203, the CCM motherboard compares whether the storage versions on the master and backup versions are consistent, if not, then go to step 204; if they are consistent, the process ends;

Step 204, if inconsistent and the storage version of the CCM main board is in a normal state, send an automatic synchronization request to the CCM standby board file by file. The data structure of the request message contains necessary information such as the file name, length, and IP address. Because the storage versions on the CCM are stored in directories, version synchronization needs to be performed directory by directory. At the same time, it is also necessary to synchronize the information file recording the directory information to the standby board;

Step 205 , after receiving the automatic synchronization request from the main board, the CCM backup board obtains corresponding files from the main board through FTP according to the information carried in the message, until the synchronization of all version files is completed.

In the above-mentioned automatic synchronization process of the storage version of the main and standby CCM boards, if the automatic synchronization fails, a synchronization failure flag is set on the CCM and standby boards. Because the storage version of the CCM backup board is already in an abnormal state at this time, if this board becomes the main board, as the initiator of synchronization, it may destroy a board with a normal storage version, so the synchronization failure flag is set to indicate that the The storage version of the board is in an abnormal state. When the CCM board whose synchronization failure flag is set is used as the main board, automatic synchronization will not occur.

In the above-mentioned automatic synchronization process of the storage version of the main and standby CCM boards, once the automatic synchronization starts, the storage version on the main and standby CCM boards is not allowed to change. The changes may include version addition, version deletion, version download, activation, deactivation, etc. . Otherwise, even if it is done automatically, it cannot guarantee that the active and standby boards of the CCM main control board are completely consistent. Therefore, when automatic synchronization is in progress, it is necessary to prohibit all other operations that may cause changes in the storage version of the main and standby boards of the CCM.

In addition, the automatic synchronization process of the OMP or RMM main and standby board storage versions of other CDMA mobile communication modules is the same as the above-mentioned automatic process of the CCM main and standby board versions.

The method for automatically synchronizing the storage versions of the main and standby boards of the communication system described in the present invention is not limited to the applications listed in the instructions and implementation methods. For those of ordinary skill in the art to which the technology of the present invention belongs, various corresponding changes and modifications can be made according to the present invention, and all these corresponding changes and modifications belong to the protection scope of the claims of the present invention.
