Method and apparatus for performing access control for WLAN interworking in wireless communication system
First Claim
1. A method for performing, by a user equipment (UE), access control in a wireless communication system, the method comprising:
- receiving access class barring information for a traffic steered from a wireless local area network (WLAN) to 3rd generation partnership project (3GPP) long-term evolution (LTE) from a network,wherein the access class barring information for the traffic steered from the WLAN to the 3GPP LTE is received via a broadcast signaling, andwherein the access class barring information for the traffic steered from the WLAN to the 3GPP LTE includes an access class barring factor and an access class barring time;
if the UE has to establish a radio resource control (RRC) connection for both the traffic steered from the WLAN to the 3GPP LTE and another connection, performing an access barring check only for the traffic steered from the WLAN to the 3GPP LTE or only for the other connection, depending on a type of the other connection,wherein the access barring check performed only for the traffic steered from the WLAN to the 3GPP LTE includes performing the access barring check using the received access class barring information; and
transmitting a RRC connection request message to the network, if a cell is not barred according to the access barring check.

Abstract
A method and apparatus for performing access control for wireless local area network (WLAN) interworking in a wireless communication system is provided. A user equipment (UE) receives access class barring information for a traffic steered from a WLAN to 3rd generation partnership project (3GPP) long-term evolution (LTE) from a network, and performs access barring check for the traffic steered from the WLAN to the 3GPP LTE using the received access class barring information. If a cell is not barred according to the access barring check, the UE transmits a radio resource control (RRC) connection request message to the network.

2. A user equipment (UE) comprising:
-
a memory; a transceiver; and a processor coupled to the memory and the transceiver, and configured to; control the transceiver to receive access class barring information for a traffic steered from a wireless local area network (WLAN) to 3rd generation partnership project (3GPP) long-term evolution (LTE) from a network, wherein the access class barring information for the traffic steered from the WLAN to the 3GPP LTE is received via a broadcast signaling, and wherein the access class barring information for the traffic steered from the WLAN to the 3GPP LTE includes an access class barring factor and an access class barring time; if the UE has to establish a radio resource control (RRC) connection for both the traffic steered from the WLAN to the 3GPP LTE and another connection, perform an access barring check only for the traffic steered from the WLAN to the 3GPP LTE or only for the other connection, depending on a type of the other connection, wherein the access barring check performed only for the traffic steered from the WLAN to the 3GPP LTE includes performing the access barring check using the received access class barring information; and control the transceiver to transmit a RRC connection request message to the network, if a cell is not barred according to the access barring check.
