Problems solved by technology

If the number of users in a certain area rises sharply due to special circumstances (such as holding major events, etc.), the MSC pool in this area will enter a high-load state, and there will be denial of service for user call requests, which will affect users' experience in using the network

Embodiment Construction

[0046] The invention provides a method for load balancing between MSC pools, which is used for load transfer between MSC pools, so that the load can be transferred from a high-load MSC pool to a low-load MSC pool, thereby making full use of existing network resources to provide services to users. The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0047] According to the relevant standards of 3GPP, all MSCs in the existing MSC pool maintain data consistency, and each MSC in the pool stores the user capacity of each MSC in the MSC pool, the total user capacity of the MSC pool, and the MSC Pool load rate and other data.

[0048] In this embodiment, in order to achieve load balancing between MSC pools, it is necessary to be able to perform load transfer between MSC pools. At the same time, in order to avoid the domino effect (that is, pool 1 with high load transfers the load to pool 2, which is also...

Abstract

The invention provides a load equalization method among MSC (Mobile Switching Center) pools, an MSC and a system. In the invention, a virtual pool server end and a virtual pool client end are added in a traditional MSC, and the virtual pool server end collects the load information of other MSC pools and transfers the load of a local MSC pool to a light-load MSC pool by establishing a virtual poolwith the light-load MSC pool so as to realize load equalization among the MSC pools, fully utilize network resources and improve user experience.

Description

technical field [0001] The present invention relates to the technical field of mobile switching center (MSC, Mobile Switch Center) pools (Pool), in particular to a load balancing method, MSC and system among MSC pools. Background technique [0002] Mobile Switching Center (MSC, Mobile Switch Center) is the core of the Global System for Mobile (GSM, Global System for Mobile) system. The interface between the communication system and other public communication networks. In the GSM system, one base station controller / radio network controller (BSC / RNC, Base Station Controller / Radio Network Controller) corresponds to only one MSC / visiting location register (VLR, Visiting Location Register). When the user's location is updated, it needs to switch to the corresponding MSC / VLR, and then obtain user data from the Home Location Register (HLR, Home Location Register). With the continuous expansion of the network, more and more location updates and handovers lead to more signaling int...
