Abstract: PURPOSE: A network management method in the case of changing a No.7 network state in an MSC(Mobile Switching Center) is provided to solve the load difference between signaling links by properly adjusting the traffic between signaling links according to a change in network states and ensuring the stability of a network. CONSTITUTION: An MTP3 message processing block in an MSC is notified that the first signaling link within a link set is turned available(S1). The MTP3 message processing block selects a signaling route within the link set(S2). Then the MTP3 message processing block checks the number of the signaling routes contained in the link set(S3). The MTP3 message processing block judges whether the ratios of signaling links between signaling routes are unequal(S4). In case that the ratios of signaling links are unequal, the MTP3 message processing block distributes SLS(Signaling Link Selection) bits to signaling routes according to the ratios of signaling links(S5). If the execution of distribution processing for all the signaling routes of the link set is completed(S6), the MTP3 message processing block continuously executes a neighboring or local signaling point restart procedure(S7).
