Method and apparatus for performing traffic steering in wireless communication system
First Claim
1. A method for performing, by a user equipment (UE), traffic steering from a 3rd generation partnership project (3GPP) access network to a wireless local area network (WLAN) in a wireless communication system, the method comprising:
- receiving, by the UE from an evolved NodeB (eNB) of the 3GPP access network, radio access network (RAN) assistance information for evaluating traffic steering from the 3GPP access network to the WLAN;
attempting, by the UE, to acquire attributes related to the RAN assistance information from a specific WLAN; and
if at least one of the attributes is not acquired from the specific WLAN, evaluating, by the UE, traffic steering from the 3GPP access network to the WLAN excluding the specific WLAN,wherein the RAN assistance information includes a WLAN signal power threshold and a WLAN load threshold.

Abstract
A method and apparatus for performing traffic steering from a 3rd generation partnership project (3GPP) access network to a wireless local area network (WLAN) in a wireless communication system is provided. A user equipment (UE) receives radio access network access network (RAN) assistance information for evaluating traffic steering from the 3GPP access network to the WLAN, and attempts to acquire attributes related to the RAN assistance information from a specific WLAN. If at least one of the attributes is not acquired from the specific WLAN, the UE evaluates traffic steering from the 3GPP access network to the WLAN excluding the specific WLAN. The RAN assistance information includes a WLAN signal power threshold and a WLAN load threshold.
