Claim Text:
1. A method for performing an access network discovery and selection function (“ANDSF”) in a user equipment operable with a Third Generation Partnership Project (“3GPP”) radio access network and a Wireless Fidelity (“Wi-Fi”) radio access network coupled to a core network, comprising: providing a location of said user equipment to an ANDSF server in said core network; reporting Wi-Fi radio access technology data from the user equipment to one of a plurality of ANDSF servers in said 3GPP radio access network over an enhanced S14 interface, said user equipment being assigned by said ANDSF server in said core network to said one of a plurality of ANDSF servers in said 3GPP radio access network based on the location of said user equipment, and said Wi-Fi radio access technology data including a basis service set (“BSS”) load indication, security information, quality of experience information, backhaul network bandwidth and average throughput; requesting local heterogeneous network extension subtree data from said ANDSF server in said 3GPP radio access network or said ANDSF server in said core network; and receiving policy information from said ANDSF server in said 3GPP radio access network based on conditions in said Wi-Fi radio access network and said 3GPP radio access network.
