A method is provided for processing emergency service calls from a user device to a PSAP, the user device having an associated line number and being configured to originate calls from fixed and mobile access networks. The method includes determining whether a call from the user device originates from a home location in a fixed access network. When the call is determined to have originated from the home location in the fixed access network, the call is routed to the PSAP, where a location of the user device is determined based on the Automatic Number Identification (ANI) included in signaling associated with the call. When the call is determined not to have originated from the home location in the fixed access network, adding pseudo-ANI to signaling associated with the call and routing the call to the PSAP, where the location of the user device is determined based on the pANI.

Enabling location determination of user device originating emergency service call

A method implemented by a proxy server is provided for routing requests for a Location-to-Service Translation (LoST) service without traversing a forest node structure. The method includes receiving a request for the LoST service initiated by a client, the request including a location of a user device and a requested service; identifying an authoritative LoST server configured to service the requested service and bounded by a service boundary that includes the location included in the request; and directly forwarding the request to the identified authoritative LoST server, without routing through any other LoST server.

Routing requests for location-to-service translation (LoST) services using proxy server

A method of providing a location of a target device to an application implementing a location based service includes receiving a request for a location of the target device from the application at a location server, the request including a location reference having a user reference referring to user information corresponding to the target device and stored in at least one data source. The method further includes retrieving the user information from the at least one data source using the user reference, determining the location of the target device based at least in part on the retrieved user information, and providing the determined location of the target device to the application.

Method and system for providing location of target device using stateless user information

A system and method for creating a location uniform resource identifier ('URI') for determining the location of a target device. A location request may be received for a target device. Location context information may be collected for the target device including starting information, validating information and policy information. This collected location context information may be encrypted in a location information server and converted to a form compatible with URI syntax. A location URI may then be constructed as a function of the converted information.

System and method for managing created location contexts in a location server

A system and method for handling a location request for a target device using a location uniform resource identifier ('URI'). A location request may be received for a target device from a requesting entity, the target device having a location context information represented by a location URI and including starting information, initial validating information and policy information. The form of the location URI may be verified by a location information server ('LIS'), the form including at least an encrypted context string. This string may be extracted and decrypted by the LIS and it may be determined whether the request can continue as a function of the policy information. If the request can continue, then an estimated location of the target device may be determined as a function of the starting information. Additional validating information may be collected and correlated the initial validating information. If these validating information correlate, then the estimated location of the target device may be provided to the requesting entity.

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.

System and method for SUPL roaming using a held client

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.

System and method for SUPL held interworking

A system and method for determining the location of a target device. A location request may be received for a target device, and a plurality of parameters determined that identify the target device. A most likely path may be selected from a plurality of paths to produce a location of the target device, each path having one or more of the plural determined parameters as an input and one or more measurement results as an output. Measurement information may be collected on the most likely path as a function of one or more of the determined parameters to provide the one or more measurement results. Location information may then be derived for the target device as a function of the one or more measurement results, the derivation utilizing a location determination function that evaluates ones of the plural paths. An estimated location of the target device may then be determined as a function of the respective location information for the selected path.
