Method and apparatus for performing handover in wireless communication system
First Claim
1. A method for performing, by a user equipment (UE), routing modification in a wireless communication system, the method comprising:
- receiving information on routing modification from a network entity of a primary radio access technology (RAT) system; and
performing the routing modification between the primary RAT system and a secondary RAT system according to the information on routing modification,wherein the secondary RAT system is used for user plane (U-plane) data,wherein the primary RAT system is a 3rd Generation Partnership Project (3GPP) Long-Term Evolution (LTE) system,wherein the secondary RAT system is an Institute of Electrical and Electronics Engineers (IEEE) 802.11 system, andwherein the information on routing modification further includes information on bearer identity (ID) including an evolved packet system (EPS) bearer ID and a data radio bearer (DRB) ID, and a logical channel ID (LCID).

Abstract
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.
