METHOD AND TERMINAL FOR ASSOCIATION UPDATE

Abstract

A method and terminal for association update are provided. When the terminal performs location area update to a MSC/VLR via a GERAN/UTRAN if it has performed combined update or CSFB attachment in an EPS network via E-UTRAN then it sets a combined update indication which indicates the EPS network requires combined update when the terminal returns to the E-UTRAN from the GERAN/UTRAN; when the terminal moves to a registered tracking area of the E-UTRAN it determines whether the combined update indication has been set or not if yes it initiates combined TAU and LAU to an MME. After receiving a location update request from the MME the MSC/VLR updates stored association information and re-establishes SGs association with the MME. Accordingly a terminal has a control module for association update which comprises a combined update indication setting determination unit a combined update setting unit and a combined update initiation determination unit. The present invention enables to update the SGs association in the MSC/VLR in time thereby the MSC/VLR can always find UE through paging.
