Research on Load Sharing of Signaling System No.7 in Telephone Network

摘要

In this paper,we studied and analyzed the load sharing mechanism of signaling system No.7 (SS7) and the principal technology of SS7.Due to the uneven reality of signaling load in the telephone network,it puts forward a solution to SS7 load sharing in the telephone network (including the load sharing within a signaling link group and among signaling link groups of inter-provincial first level circuit,interprovincial secondary circuit and provincial circuit).The load sharing solution keeps load balancing among signaling links and among signaling link groups in the telephone network.Furthermore,the solution can effectively improve the reliability of SS7 and ensure the continuity of the telephone service.
