How to deal with failures of personal mobile switching centers

摘要

The present invention relates to a failure handling method of a personal mobile communication exchange for promptly responding to a failure of any one of the redundant signal message handling processors (SMHPs) in a subsystem of the personal mobile communication exchange. In the prior art, when a message for requesting a call processing is sent to each of the redundant SMHPs in the No.7 subsystem, the operating system sends a message for the call processing twice so that each of the duplicated SMHPs is received. In addition to longer message transmission times, each of the redundant SMHPs had to receive and process messages that did not apply to them. Accordingly, in the present invention, when the user wants to send a message for a call processing request to the SMHP in the subsystem No. 7 according to the request of the user part 24, the operating system normally operates the message for the call processing request. By sending only one time to the corresponding SMHP, the message transmission time is shortened and the normally operated SMHP receives and processes only the message corresponding to itself, thereby reducing the load and improving the performance of the overall system, thereby improving the above-mentioned defects. will be.
