Embodiment Construction

[0057] Embodiments of the present invention provide a method and device for user migration. The source MSC sends a migration request message to the MME, wherein the migration request message carries the information of the migration user and the target MSC information; the source MSC receives the dismantling message sent by the MME; wherein , the dismantling message is sent after the MME establishes the SGS association based on the relocated user with the target MSC according to the relocation request message; the source MSC dismantles the SGS association based on the relocated user with the MME according to the dismantling message. Since user migration information can be transmitted between MSC and MME, MME completes user migration based on the information transmitted by MSC, thereby solving the problem of CSFB user migration, further balancing the service load between MSCs, and improving resource utilization. and system performance.

Abstract

The present invention relates to the technical field of mobile communications, and especially relates to a user migration method and device, thus to solve the migration problem of circuit switched fallback (CSFB) users. The method comprises the steps of a source mobile switching center (MSC) sends a migration request message to a mobility management entity (MME), the migration request message carrying information of a migration user and target MSC information; a source MSC receives a dismantling message sent by the MME, the dismantling message being sent after the MME establishes migration-user-based SGS relevance with the target MSC according to the migration request message; and the source MSC dismantles the migration-user-based SGS relevance with the MME according to the dismantling message. Because the user migration information can be transmitted between the MSC and the MME, user migration is completed by the MME according to transmitted information of the MSC, thereby solving the CSFB user migration problem, further balancing traffic loads among the MSCs, and raising a resource utilization rate and system performance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for user migration. Background technique [0002] The CSFB (Circuit Switched Fallback, circuit domain fallback) solution deployed nationwide by China Mobile's 4G Phase I project is through each MSC Pool (Mobile Switching Center Pool, mobile switching center pool) in the CS (Circuit Switched Domain, circuit switched) domain. The MSC (Mobile Switching Center, Mobile Switching Center) is transformed, and the transformed MSC and MME (Mobility Management Entity, Mobility Management Module) have SGS interfaces to provide voice calling and calling and short message services for 4G users. [0003] When a CSFB user registers on the network for the first time, the joint attachment process will be carried out. After receiving the user's joint attachment request, the MME will determine the MSC distributed for the CSFB user according to a certain correspondi...
