Abstract

The invention discloses a method and a system for redistributing user service gateway, and a mobile management entity, and relates to the field of information communication. The method comprises: when UE is in a connected state, the mobile management entity storing an eNodeB address distributed by an eNodeB and a TEIDs; the MME initiating SGW redistribution, selecting a new SGW, and maintaining the UE in the connected state; the MME requesting the new SGW to establish loading, the new SGW establishing a downlink after obtaining the eNodeB address and the TEIDs; the MME using a service gateway switching request to request the eNodeB to switch over to the new SGW, after the eNodeB obtains the new SGW address and the TEIDs, switching being completed, and establishing an uplink. The method, the system, and the entity provide a service gateway rapid redistribution scheme in an LTE network when a user is in a connected state, so that a new SGW can be selected for users in the connected state. The method, the system, and the entity realize unchanged user state and business without interruption, so as to improve user business experience.

Description

technical field [0001] The present invention relates to the technical field of the information communication field, in particular to a user service gateway reallocation method, system and mobility management entity. Background technique [0002] Under the SGW (Service Gateway, Service Gateway) redistribution mechanism of the LTE (Long Term Evolution, Long Term Evolution) network currently standardized by 3GPP (3rd Generation Partnership Project), when the user is in the connected state, the user needs to be Turn to idle state, and then switch the user to the new SGW. figure 1 It shows the SGW reallocation process when the user is in the connected state according to the 3GPP standard. Such as figure 1 As shown, for example, MME (Mobile Management Entity, Mobility Management Entity) detects SGW failure / overload, when the user terminal (UE) is in the connected state, when MME decides to perform SGW reallocation (step 1); MME first releases S1 bearer resources , the evolved N...
