Embodiment Construction

[0035] The interface between the WT and a radio access network node (such as an LTE eNB) may be set up after radio measurement reporting by one or more WLAN-enabled UEs to the serving eNB. For example, after the UE reports the relevant parameters it detects for one or more WLANs (eg ESSID, BSSID, channel, signal strength, etc.), the eNB may attempt to set up an interface with one or more appropriate WTs. This interface may be called, for example, the "Xw interface," but this interface may have or will have a different name in certain embodiments of the systems described herein.

[0036] Prior to this disclosure, there was no way for the eNB to correlate the radio information reported by the UE with the appropriate network address or addresses needed to set up the Xw interface. The eNB may have been pre-configured with one or more ESSIDs or one or more BSSIDs present in the eNB's neighborhood to be broadcast in a system information block (SIB) as assistance data for the UE, but...

Abstract

A node of the Radio Access Network RAN ​​receives (402) from a WLAN terminal 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 (404) a mapping between ESSIDs and / or BSSIDs and corresponding WLAN access points of WTs. Based on the mapping, the node associates (406) the UE with the WLAN access point in response to receiving a measurement report from the UE, the measurement report indicating the ESSID and / or the BSSID. An interface may be established ( 408 ) between the node and the WT.

Description

technical field [0001] The present invention relates generally to wireless communication networks, and in particular to interfaces between cellular networks and WLAN networks. Background technique [0002] Has been adopted by IEEE in the 802.11 series of specifications (i.e., such as "IEEE Standard for Informationtechnology-Telecommunications and information exchange between systems. Localand metropolitan area networks-Specific requirements. Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications ”) to standardize the wireless local area network (WLAN) technology known as “Wi-Fi”. The IEEE 802.11 specification regulates the functions and operations of Wi-Fi access points (APs) or wireless terminals (collectively referred to as "stations" or "STAs" in the IEEE 802.11 standard), including physical layer protocols, media access control (MAC) layer protocols and other aspects required to ensure compatibility and interoperability between access ...
