Abstract

The disclosure relates to automatically configuring a map of inter-access technology neighbor relations. In this neighbor relations map configured by an ANDSF, relationships between neighboring cells of differing access networks of the same or different access technologies are maintained including extra-domain and non-domain neighbor relationships. A domain refers to a domain of one or more access technologies in which ANDSF is not required for intra-domain access selection and discovery. ANDSF configures the map based on neighbor relations data reports from wireless terminals, which record the neighbor relations data as they perform extra-domain or non-domain handovers or reselections or as they scan their surroundings. ANDSF provides steering instructions to configure the neighbor relations data recording and reporting behaviors of the wireless terminals. ANDSF provides access network discovery and selection information, which indicates availability of non-domain accesses, and in some cases domain accesses, to wireless terminals based on their locations.
