Method and system for realizing soft unloading of multi-homing core network element

Abstract

The invention discloses a method for realizing soft unloading of a multi-homing core network element, which comprises the following steps: A, setting the multi-homing core network element to be unloaded into a local closing state, and not allocating new services to the multi-homing core network element; and B, unloading the multi-homing core network element when the prior service of the multi-homing core network element to be unloaded is processed to a preset state. The invention also discloses a system for realizing the soft unloading of the multi-homing core network element. The method and the system carry out unloading when the prior service allocated on the multi-homing core network element to be unloaded is processed to the preset state, and the prior service allocated on the multi-homing core network element to be unloaded is initiatively released and cannot be passively released because of unloading the multi-homing core network element to be unloaded so as to reduce the call loss and reduce the influence on the prior service.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for soft offloading of core network elements in a multi-homing networking mode. Background technique [0002] In the Global System Mobile (hereinafter referred to as GSM), usually, a base station controller (hereinafter referred to as BSC) can only be connected to one mobile switching center (Mobile Switch Center or Mobile Switch Center emulator, hereinafter referred to as MSC), such as Figure 1 shown. [0003] BSC multi-homing networking means that a BSC can connect to multiple MSCs, such as figure 2 shown. The serving node selection function (hereinafter referred to as SNSF) is responsible for selecting MSCs, distributes services to each MSC for processing through a certain algorithm, and realizes load sharing between MSCs through dynamic adjustment of distribution, such as code division multiple access ( A-Flex in the field of Code Division Multip...

Problems solved by technology

At the same time, all existing services on the MSC will be interrupted at the moment of MSC failure

[0005] When a certain MSC is going to be upgraded or relocated or the MSC is not needed for some reason, the MSC will be artificially caused to fail, so that the new services of the terminals originally allocated on the MSC will be redistributed to other terminals. on MSC

However, the current services on the MSC will be completely interrupted at the moment of the MSC failure, resulting in serious call loss and other problems. and other serious consequences
