Abstract
A system and method for assisting the H-SLP is selecting a V-SLP using the HELD client of a SET. The SET receives identity information from an access network regarding associated LIS. The SET relays this information as well as measurements taken of the wireless network to the H-SLP. If the H-SLP does not contain enough information to determine a location estimate, the H-SLP uses the identity information from the access network to find an associated SLP that may serve as a V-SLP. A request using roaming location protocol may then be transmitted from the H-SLP to the V-SLP for location assistance.
