Abstract

Improved non-cellular (e.g., Wi-Fi) link integration with a cellular (e.g., LTE) network is described. The improved link integration can relate to utilizing an eNodeB device (e.g., residing in a radio access network portion of a cellular network) as an anchor point rather than a packet data network gateway device (e.g., residing in a core network portion of the cellular network) utilized by other approaches. The improved link integration can maintain full compliance with or support for other approaches, and can reduce signaling overhead, simplify quality-of-service management, and/or provide a more rapid reaction to changes of access, particularly in cases where the eNodeB device and a non-cellular access point device are co-located.
