Abstract
A WiFi Access Point (AP) controller with location capabilities (e.g., an MSE) provides location to a SUPL location server platform (SLP), for response to a network location request. WiFi AP controllers are enabled to communicate with the SLP. WiFi location measurements are transferred via SUPL to the SUPL location server. An AP to WiFi AP controller mapping database provides an association of a WiFi AP controller list to the access points (AP) they manage. The AP to WiFi controller mapping database, together with SUPL messaging between a SUPL location server and the AP controllers, provides WiFi-determined precise location across networks from the SLP. A specific MSE is identified by the AP to WiFi controller mapping database, and queried, by the SLP for WiFi based positioning of mobile devices. In other embodiments a plurality of MSE's are identified, and queried, and a WiFi location is received from at least one.
