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.
Claims27
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 (LIS) 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,
- wherein the identifying information comprises the uniform resource identifier (URI) of at least one of the plurality of location information servers.
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 hypertext transfer protocol (HTTP) enabled location delivery (HELD) device comprising:
- initiating a SUPL session;
- accessing a network having an associated plurality of location information systems (LIS) and at least one associated SLP;
- requesting identity infoimation 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,
- wherein the identity information comprises at least a uniform resource identifier (URI).
A method of locating a SUPL enabled terminal (SET) mobile device having a hypertext transfer protocol (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 home secure user plane location platform (H-SLP) location information regarding location information servers (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 visiting secure user plane location platform (V-SLP) based on the location information;
- and,
- initiating a roaming protocol with the V-SLP, and locating the mobile device in the V-SLP,
- wherein the location information is a location uniform resource identifier (URI).
A system for selecting a visiting secure user plane location platform (V-SLP) for a roaming mobile device comprising:
- a SUPL enable Terminal (SET) having an integral hypertext transfer protocol (HTTP) enabled location delivery (HELD) client;
- a local Access network assessable by the HELD client of the SET;
- one or more location information systems (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 home secure user plane location platform (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,
- wherein said identity information is a location uniform resource identifier (URI).
