1. A method of locating a mobile device comprising:
- connecting the mobile device to an access network;
discovering a location information server (LIS) over the connected access network;
obtaining location information from the LIS over the connected access network;
measuring characteristics of a wireless communications network at the mobile device to obtain network measurements;
sending a message from the mobile device to a location center, wherein the location center is a SUPL (Secure User Plane Location) Location Platform (SLP), said message containing location information received from the LIS and the network measurements;
determining if the location information server is trustworthy; and
,determining a location based at least upon the location information.

Abstract
A system and method for enhancing a SUPL session where a SET with a HELD client discovers an LIS of an access network and provides information received from the LIS or plurality of LISs to the SLP. The SLP determines the trustworthiness of the location information and estimates a location. The degree to which the SLP uses the location information is a function of the trustworthiness of the LIS and restraints on the location request. The location information may include a URI or domain name or other indication of location.

12. A method of estimating the location of a SUPL (Secure User Plane Location) enabled terminal (SET) comprising:
-
receiving information over a secure user plane from the SET, said information including at least the URI (Uniform Resource Identifier) of a LIS (Location Information Server) and network measurements; determining if the LIS is trustworthy based on the received information; estimating the location of the SET based on at least the received information and the trustworthiness of the LIS; and
,providing an estimated location over the secure user plane to the SET, wherein the steps are performed by a SLP (SUPL Location Platform). - View Dependent Claims (13, 14)

23. A method for generating a location estimate using multiple communication connections comprising:
-
connecting to an access network; receiving location information from a location information server (LIS) on the access network; sending at least a portion of the location information to a location center, wherein the location center is a SUPL (Secure User Plane Location) Location Platform (SLP); and
,receiving the location estimate from the location center, wherein the location estimate is a function of at least the portion of the location information.

28. A system for locating a mobile appliance comprising:
-
a SUPL (Secure User Plane Location) enable terminal (SET) having a resident HELD (Http Enable Location Delivery) client; a local access network accessible by the HELD client of the SET; a location information server (LIS) connected to the local access network; a SLP SUPL Location Platform (SLP) capable of estimating a location; and a wireless communication network connected to the SLP, wherein said SET being capable of taking measurements of the wireless communication network, and wherein information received from the LIS over the local access network is communicated from the SET along with the network measurements over the wireless communication network to the SLP for estimating the location of the SET.
