Problems solved by technology
As the main control board of the entire system information center, it records all the data required for communication. In the existing technology, there are many explanations on how to realize the timely switchover of hardware and the synchronization technology of database master and backup, but how reliable the state machine of the protocol process is. It is not mentioned that it is synchronized to the standby board. For the protocol processing board, this part of the synchronization is very important. The protocol state machine changes rapidly and the amount of data is large, so it cannot be completely relied on the database module for synchronization. If the data information is not accurate and reliable Synchronize to the standby board in time. After the switchover, the communication of some users will be interrupted or even paralyzed, causing adverse effects on telecom operators.

Embodiment Construction
[0013] According to the functional division of different protocol modules, the modules are run in different tasks, and several processes are run in each task to realize the protocol functions of different levels in the protocol. Define the static number of process instances, the maximum number that can be created, and the size of the instance data area. The instance data area records information about the instance itself. A single-instance master control process is defined in each module, which is statically created by the operating system when the system starts, and is responsible for the creation of several other process instances in this module. After each process instance is created, the operating system will send an initialization message. After the process instance receives the initialization message, it can be responsible for the initialization of the instance data area:
[0014] After the standby board is powered on, the main control process of each module requests the...

The method includes steps: based on module function according to different protocols, module is operated at different tasks; after power on, main control process on each module of the spare board requests information of process instance created dynamically to main control process corresponding to main board; main control process calls creation for process instance; when the called instance receives message for ending the call process, or before the instance is need of stopping running, message is sent to the process of corresponding instance of the spare board to inform it to stoop running. Carrying out synchronization of protocol instance, the invention implements rearrangement between main board and spare board in few milliseconds. The invention guarantees success of rearrangement between main board and spare board, and raises stability of communication system.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a method for synchronizing master and backup software of a master control protocol processing board. Background technique [0002] In order to improve the stability of the system, the protocol processing board in the communication equipment adopts 1+1 hot backup mode. When the main board fails, the backup board can start running immediately, thus ensuring uninterrupted communication. As the main control board of the entire system information center, it records all the data required for communication. In the existing technology, there are many explanations on how to realize the timely switchover of hardware and the synchronization technology of database master and backup, but how reliable the state machine of the protocol process is. It is not mentioned that it is synchronized to the standby board. For the protocol processing board, this part of the synchronization is very impo...
