A mobile service switch center server for selecting route

Abstract

The invention discloses a server for realizing a routing selection function in an exchange center of a mobile service, which includes a call control module, a routing selection module and a storage module. The call control module accepts the calls from a gateway on the accessing side and controls an MGW on a bearing path to establish bearing according to bearing link information; the routing selection module calculates parameters of nervousness degree on each path according to total number of resource allocation and the total number of occupied resource, selects the bearing path and transmits the information to the call control module; the storage module stores the configuration parameters of the routing resource. The invention overcomes the defect of congestion caused by unfair resource allocation between the gateways in a multi-gateway model so that the whole network can be operated in a controllable, stable and fair way.

Description

technical field [0001] The invention relates to a mobile service switching center server of a 3GWCDMA-R4 core network in the communication field, in particular to a mobile service switching center server for realizing routing selection function. Background technique [0002] 3GWCDMA-R4 (3G refers to the third-generation mobile communication technology, WCDMA refers to wideband code division multiple access, R4 is the version number) The basic structure of the network is the separation of bearer and control, and the control part of the call is concentrated in the MSC Server (Mobile Service Switching Center) server), and the bearer and connection part of the call is concentrated on the MGW (media gateway). The typical network architecture is that one MSC Server controls one MGW, and multiple sets of such devices are interconnected to form a network. But the disadvantage of this networking mode is that each MGW needs an MSC Server to control it, which will lead to repeated inve...

Problems solved by technology

Therefore, there is another way of route selection, which is based on the load sharing method. This method simply uses the proportion of resources as the weight to allocate traffic to two different paths. There are more resource allocations. The allocated traffic volume is larger, and the allocation of resource allocation is less. However, this method does not consider the user's call time. Some users may hang up soon after making a call, while some users may hang up. If the call takes a long time, bearer resources will always be occupied

On the other hand, there may not only be traffic between these two gateways on the path of the current call, but there may also be traffic between other gateways, and these two gateways do not make the traffic of this path busy. The change of degree is used as the basis for route selection, so the final result will be disordered and uncontrollable, and it is also prone to resource exhaustion, but the probability of this situation is reduced.

[0006] It can be seen that the technologies and routing strategies currently used in practical applications are actually unfair, and they cannot better coordinate resource utilization and allocation among gateways in the multi-gateway model.
