Abstract  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 then it sets a combined update indication which indicates the EPS network requires combined update; when the terminal moves to a registered tracking area of the EPS network 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 association in the MSC/VLR in time thereby the MSC/VLR can always find UE through paging.
