Wi-Fi Roaming - Building on and SF and Hotspot 2.0

This research collaboration paper between Alcatel-Lucent and BT describes the need for heterogeneous network policies in a multi-operator environment. It analyses how new standards like the 3GPP Access Network Discovery and Selection Function (ANDSF) and the Hotspot2.0 initiative can complement each other to meet those needs whilst identifying a number of use-case scenarios where further standards work is required. ANDSF is a cellular technology standard which allows an operator to provide a list of preferred access networks with policies for their use up to the granularity of a single IP flow or all traffic for A given PDN Network (APN).
