Embodiment Construction

[0045] Embodiments of the present invention provide a load migration method, system, and device based on an MSC pool. When load imbalance among MSCs occurs in an MSC pool and users need to be migrated to other MSCs in the pool, a modification notification can be sent to non-access Layer node selection function implementation node (NNSF, NAS NodeSelect Function), the modification notification carries the user ID of the migrated user and the target MSC ID, and the target MSC is the MSC to which the user is to be migrated, and NNSF according to the Modify the routing relationship table by modifying the user ID and the target MSC ID of the migrated user carried in the notification, and modify the MSC corresponding to the user ID in the routing relationship table to the target MSC, and then according to the modified routing relationship table, Sending the message containing the user identifier to the destination MSC, so as to realize load migration.

Abstract

The embodiment of the invention discloses a MSC pool-based load migration method, a system and a device thereof. The method provided by the embodiment of the invention comprises the following steps: a modification notice comprising the subscriber identity of a subscriber to be migrated and a destination MSC identity is obtained; the destination MSC is the MSC to which the subscriber is migrated; a routing relation table is modified according to the subscriber identity and the destination MSC in the modification notice, so that the MSC corresponding to the subscriber identity in the routing relation table is modified into the destination MSC; according to the modified routing relation table, a message comprising the subscriber identity is sent to the destination MSC so as to realize the load migration; thereby the load can be re-allocated through a load migration process at the time of MSC upgrading or an abnormal load in a MSC pool area.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a load migration method, system and equipment based on a mobile switching center (MSC, MobileSwitch Center) pool. Background technique [0002] In Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access), Time Division Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access), Global System for Mobile Communications (GSM, Global System for Mobilecommunications) In the field of technology, since the 5th edition of the 3rd Generation Partnership Project (3GPP R5, 3rdGeneration Partnership Project 5th Release), the Iu / A-Flex function has been introduced, that is, the radio network controller / base station system controller (RNC / BSC, Radio The Network Controller / Base Station Control) supports an intra-domain connection routing function from one RNC / BSC node to multiple core network (CN...
