Positioning for WLANs and other wireless networks

A method of supporting Secure User Plane Location (SUPL), the method comprising:

• determining access point (AP) information of an AP in a wireless local area network (WLAN);
• receiving, by a SUPL Enabled Terminal (SET), a SUPL message from a SUPL Location Platform (SLP), the SUPL message including one or more parameters identifying a network measurement information that is supported by the SLP, the network measurement information supported by the SLP comprising one or more types of radio access networks and associated network measurement device and signal characteristic information for at least one of the one or more types of radio access networks;
• responsive to a determination that the one or more types of supported radio access networks includes the WLAN, and further responsive to a determination that the AP information includes the network measurement information that is supported by the SLP, filtering the AP information based on the one or more parameters, the filtered AP information including only the network measurement information supported by the SLP for the WLAN;
• and
• sending a second SUPL message to the SLP, the second SUPL message including the filtered AP information.

An apparatus including a Secure User Plane Location (SUPL) Location Platform (SLP), the SLP comprising:

• a processor configured to:
• initiate transmission of a SUPL message including one or more parameters identifying network measurement information that is supported by the SLP, the network measurement information supported by the SLP comprising one or more types of radio access networks and associated network measurement device and signal characteristic information for at least one of the one or more types of radio access networks, the transmission being to an SUPL Enabled Terminal (SET) in a wireless local area network (WLAN) to enable the SET to:
• determine that the one or more types of supported radio access networks includes the WLAN, and
• filter, based on the one or more parameters, access point (AP) information obtained by the SET to generate filtered AP information, the AP being in the WLAN, and the filtered AP information including only network measurement information supported by the SLP;
• receive a second SUPL message from the SET, the second SUPL message including the filtered AP information;
• and
• determine location information for the SET based on the filtered AP information;
• and
• a memory coupled to the processor.
