Abstract
A system and method is provided for performing an access network discovery and selection function in a communication system. An access network discovery and selection function (“ANDSF”) server is 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. The ANDSF server is configured to communicate with a user equipment over an enhanced S14 interface. The enhanced S14 interface comprises 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. The ANDSF server is also configured to provide policy information to the user equipment based on conditions in the Wi-Fi radio access network and the 3GPP radio access network.
