A node of a radio access network (RAN) receives, from a WLAN Termination (WT), an Extended Service Set Identifier (ESSID) and/or a Basic Service Set Identifier (BSSID) for one or more WLAN access points controlled by the WT. The node maintains a mapping between the ESSIDs and/or the BSSIDs and corresponding WLAN access points of the WT. Responsive to receiving a measurement report from a UE, the measurement report indicating an ESSID and/or a BSSID, the node associates the UE with a WLAN access point, based on said mapping. An interface may be established between the node and the WT.
