Method of application layer controlled NO 7 signaling dynamic route selection

Abstract

The invention relates to a method to select an application-layer controllable No. 7 signaling dynamic route, a network-layer uses a route table to dynamically select an available signaling route, the method also includes that the application-layer sends request information to the network-layer; the network-layer feeds back to the application-layer the route selecting result which corresponds to the request information; the application-layer adjusts the route table according to the route selecting result and the content of the route table. The method, based on the prior protocol, feeds back the route selecting result to the application-layer through the network-layer, the application-layer does not change the selecting way of the prior route and just decides whether the dynamic route selecting range is adjusted according to the information processing condition, thereby realizing the method to select the application-layer controlled No. 7 signaling dynamic route. The method solves the problem that the application-layer can directly adjust the selection-awaited No.7 signaling route when the information route is not successful or can not meet the requirement of the application-layer, and reduce the unnecessary call loss; the method is the beneficial supplement and perfection of the prior signaling route.

Description

technical field [0001] The invention relates to a mobile communication core network, in particular to a method for supporting the No. 7 signaling application layer (ISUP, MAP, etc.) to control signaling dynamic routing in the LMSD stage of the third generation mobile communication. Background technique [0002] At present, there are three kinds of international standards in the third generation of mobile communication, any of which supports the docking with the traditional telecom No. 7 equipment, which includes MSC, HLR and PSTN. For example, in the LMSD stage of CDMA2000, MSCe / MGW, HLRe, and SCPe respectively implement simulation devices such as mobile switching center, user location register, and intelligent control node. In order to solve the adaptation between the circuit domain and the IP domain carrying SS7, the Sigtran protocol is adopted, but the signaling route selection basis of SS7 is still the routing keyword or destination signaling point code provided by the a...

Problems solved by technology

When STP-2 fails and the message transmitted by Route2 is discarded, since the application layer cannot know the specific route of the message and the network layer does not necessarily block Route2 according to the protocol, the next time the application layer selects a route, it will select Route2 with the same probability , resulting in a certain degree of call loss
