No. 7 Processor of Mobile Communication Switch

摘要

The present invention relates to a method for managing a redundant configuration of a No. 7 processor that processes and manages a No. 7 signaling protocol, which is a communication protocol between an exchange and a control station, in a stable and reliable manner. If the processor is down due to one of the faults occurring in the process of sharing, it is detected by the other one as a hardware interrupt, and it is determined and processed, and the application program is informed of the downside of the counterpart processor, Process all the loads continuously, and when one side is restored, it treats the opponent processor as a living state, so that it can process continuous signal in other processor when the processor is down, so that a large amount of signal can be processed and the stability of signal processing can be improved .
