Method and apparatus for controlling wlan bearer

A method for performing a cellular network and a wireless local area network (WLAN) aggregation for a user equipment (UE) by a WLAN termination (WT), the method comprising:

• receiving, from a base station, WLAN aggregation request message including at least one of an identifier of a public land mobile network (PLMN), an identifier of the UE, a UE identifier over a Xw interface, and information of bearer on the base station side;
• transmitting, to the base station, WLAN aggregation response message indicating a WT association confirmation in response to the WLAN aggregation request information;
• and
• receiving, from the base station, user plane data for the UE in case that the UE is associated with the WLAN based on the WLAN aggregation response message.

A base station for performing a cellular network and a wireless local area network (WLAN) aggregation for a user equipment (UE), the base station comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to control to:
• transmit, to a WLAN termination (WT), WLAN aggregation request message including at least one of an identifier of a public land mobile network (PLMN), an identifier of the UE, a UE identifier over a Xw interface, and information of bearer on the base station side,
• receive, from the WT, WLAN aggregation response message indicating a WT association confirmation in response to the WLAN aggregation request information, and
• transmit, to the WT, user plane data for the UE in case that the UE is associated with the WLAN based on the WLAN aggregation response message.
