METHOD AND APPARATUS FOR PERFORMING HANDOVER IN WIRELESS COMMUNICATION SYSTEM

摘要

A method for and apparatus for performing handover in a wireless communication system is provided. A wireless device transmits measurement results configured for a secondary radio access technologies (RAT) system, receives information on routing modification based on the measurement results, from a network entity of a primary RAT system and performs a handover to a target access network according to the information on routing modification. The secondary RAT system is used for a user plane (U-plane) data, and the handover is determined based on at least one of a quality of service (QoS) information, load information about the primary RAT system and secondary RAT system, and a network preference information of the UE.
