Abstract

Disclosed are a method and an apparatus for maintaining service continuity of a user equipment (UE) after a tracking area is updated. The method comprises: after a UE initiates a tracking area update (TAU) request, a mobility management entity (MME) determining whether an updated target service gateway (SGW) is the same as a source SGW (S302); in the case that a determination result is no, the MME further determining whether an evolved base station (eNodeB) currently accessed by the UE is changed (S304); and in the case that the eNodeB is not changed, the MME selecting the target SGW to serve the UE and sending the eNodeB a notification message indicating that the UE is handed over to a serving area of the target SGW, or the MME stopping selecting an SGW for the UE but directly instructing the UE to continue to be served by the source SGW (S306). The present invention can maintain service continuity of a UE after a TAU process, thereby improving the user experience.
