A relocation determination device of an SRNS(Serving Radio Network Subsystem) of a WCDMA(Wideband Code Division Multiple Access) system and a method thereof are provided to check the point of time when SRNS relocation is performed, if a UE(User Equipment) is located in a border area between an SRNC(Serving Radio Network Controller) and a TRNC(Target Radio Network Controller), thereby solving a waste of resources and system loads caused by ping-pong phenomena caused by movement of the UE. A cell update message is received from a UE(301). A cell where the UE is located is checked to examine whether the UE exists in the cell of a TRNC(303,305). If so, it is examined whether the cell for uploading the cell update message is contained in neighbor cells of an SRNC(307). If not, combined cell/URA(UTRAN Registration Area) update and SRNS relocation is carried out(309). |
