Problems solved by technology

[0006] The present invention provides a mobile communication system and a method for reducing interface signaling traffic, which is used to solve the problem in the prior art that there is a large amount of interactive signaling on the D interface between the VLR and the HLR because the HLR needs to be updated every time the VLR changes. Redundancy causes network performance degradation

Embodiment Construction

[0028] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0029] The idea of ​​the present invention is that in a large local network, although the mobile service switching center MSC is logically regarded as a plurality of virtual switches, it is still a switch physically, and the HLR and MSC / VLR pass through the C / D interface. The signaling interaction is performed through external messages. Therefore, the purpose of reducing the external message interaction signaling of the C / D interface can be achieved through the internal message interaction between the VLRs on a physical switch. That is, when the mobile terminal in the large local network performs location update, it only updates the user data between VLRs in the large local network or updates the corresponding relationship between VLRs, and the data is still stored in the anchored VLR instead of the HLR. The user data is updated, thereby reducing...

Abstract

A method for decreasing flow rate of interface signaling includes setting up corresponding relation of the first access position register to the second access position register in the first access position register through signaling interaction of two said registers when terminal is moved from service area of the first access position register to service area of the second one, obtaining terminal position according to user data stored in the first access position register by terminal at time of position-updating and according to said corresponding relation.

Description

technical field [0001] The invention relates to signaling flow control technology in the field of wireless communication, in particular to a mobile communication system and a method for reducing interface signaling flow. Background technique [0002] In the 2G network era, since the core network uses the main switching center (MSC, Main Switching Center) equipment that integrates bearer and control, in non-user-intensive areas, wide coverage and large capacity are a pair of contradictions that cannot be resolved: If one MSC is placed in each local network, more main equipment, auxiliary equipment and operation and maintenance personnel are required, which will inevitably lead to the above-mentioned problems of low equipment and personnel utilization, small input-output ratio, and unreasonable network structure. ; If multiple local networks share one MSC, due to the long distance between the local networks, there is a serious problem of long-distance routing of local traffic ...
