SYSTEM AND METHOD FOR SUPL ROAMING USING A HELD CLIENT
First Claim
1. A method of assisting in the selection of a visiting secure user plane location platform (V-SLP)for a mobile device, wherein the mobile device is tasked to gather characteristics of a wireless communications network and report the characteristics to a home secure user plane location platform (H-SLP) of which the mobile device is associated, comprising:
- accessing a network having an associated plurality of location information servers and at least one associated secure user phone location platform (SLP);
searching for at least one of the plurality of location information servers;
receiving identifying information of at least one of the plurality of location information servers; and
,transmitting the identifying information and the characteristics of the wireless communications network to the H-SLP to thereby assist the H-SLP in the selection of a V-SLP.

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.

10. A method of selecting a second secure user plane location platform (SLP) for a mobile device, wherein the mobile device is an integrated secure user plane location (SUPL) and HTTP enabled location delivery (HELD) device comprising:
-
initiating a SUPL session; accessing a network having an associated plurality of LIS and at least one associated SLP; requesting identity information for at least one of the plurality of LIS; receiving the identity information at the mobile device; transmitting the identity information and network measurements from the mobile device to a first secure user plan location platform; and
,receiving the identity information at the first SLP and selecting the second SLP based on the identity information. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method of locating a SUPL enabled terminal (SET) mobile device having a HTTP enable Location delivery (HELD) client, comprising:
-
initiating a location session; requesting network measurements of a wireless communications network from the mobile device; receiving at a H-SLP information regarding LISs associated with a network accessible by the mobile device as a HELD client along with the network measurements; and
,selecting a SLP as a V-SLP based on the information; and
, initiating a roaming protocol with the V-SLP, and locating the mobile device in the V-SLP. - View Dependent Claims (23, 24, 25)

26. A system for selecting a V-SLP for a roaming mobile device comprising:
-
a SUPL enable Terminal (SET) having an integral HELD client; a local Access network assessable by the HELD client of the SET; one or more LIS associated with the local access network, wherein at least one of the LIS is a SLP wherein identity information regarding the LISs associated with the local access network is provided to the mobile device over the local access network; a H-SLP associated with the mobile device, wherein the identity information is transmitted from the mobile device to the H-SLP over a wireless communication network; and
,the H-SLP determines a V-SLP from the at least one SLP based on the identity information. - View Dependent Claims (27, 28, 29, 30)
