Embodiment Construction

[0024] Carefully analyze the resource waste or call unreachable problems caused by the route selection method currently existing in the network where control and bearer are separated. The key is that after the originating office (front office) receives the assigned roaming number, by analyzing the roaming number, Only the MSC of the landing office can be determined, and the MGW controlled by the landing office cannot be determined, because there is no direct control flow dialogue between them. However, the originating office must designate a CIC resource on the MGW in order to establish a service connection. Therefore, this is As a result, there is no basis for the front office to designate the MGW controlled by the landing office, and it is often not the MGW expected by the landing office.

[0025] Through the above analysis, the core idea of ​​the present invention is to virtualize multiple MGWs controlled by the MSC into common mobile switching offices (MSC Server or MSCe) i...

Abstract

The method includes following steps: the media gateway controlled by mobile switch center is virtualized into a virtual mobile switch center, and then the roaming number is reallocated between multi virtual mobile switch centers; when a routing request from the mobile switch center at calling party is received, looks up the base station controller / radio network controller where the user locates at; by the preset translation table, selects and finds the media gateway directly connected to the base station controller / radio network controller; allocates the roaming number; the mobile station center at calling party allocates circuit ID code for the virtual mobile switch centers in term of the roaming number, and then transmits the initiation address message, and finally controls the relevant media gateway to make call connection with the mobile switch center at calling party in term of the circuit ID code and the initiation address message.

Description

technical field [0001] The invention relates to a routing selection method in a mobile communication network, in particular to a routing selection method suitable for a mobile communication network in which bearer and control are separated. Background technique [0002] The third generation of mobile communication (abbreviated as 3G) is one of the most popular communication technologies at present. There are currently three international standards, namely WCDMA in Europe, CDMA2000 in the United States and TD-SCDMA in China. [0003] 3G technology is still in constant development and evolution, and there are significant changes in the network structure. WCDMA and TD-SCDMA share the same core network, and will eventually develop into an all-IP stage. The R99 version of WCDMA and CDMA2000 The core network of the core network becomes the separation of control and bearer, that is to say, the service flow and the control flow of the control service flow are separated, and the netw...
