Abstract:
Disclosed are systems, methods and devices for responding to changes in a wireless access type occurring in connection with a handover event affecting a mobile terminal while the mobile terminal is engaged in a position determination session with a location server. If a first positioning protocol employed in the position determination session is not supported or enabled by the changed wireless access type, the position determination session may be resumed or restarted using a second positioning protocol supported or enabled by the changed wireless access type.
Abstract:
Techniques are provided which may be implemented in various methods, apparatus, and/or articles of manufacture to allow a mobile device to obtain certain location service(s) and/or the like from one or more computing devices that have been authorized for use. For example, in certain implementations, an authorizing location server may obtain a first message from a mobile device indicating a first set of location servers, determine a second set of location servers based, at least in part, on the first set of location servers, and transmit a second message to the mobile device indicating that the second set of location servers are authorized for location service related access by the mobile device.
Abstract:
The subject matter disclosed herein relates to a system and method for determining indoor context information relating to a location of a mobile device. Indoor context information may be utilized by a mobile device or a network element to obtain an estimate of a location of the mobile device within an indoor environment.
Abstract:
The subject matter disclosed herein relates to a system and method for negotiating a version of Secure User Plane Location (SUPL) between a network entity and a SUPL enabled terminal. In a particular implementation, a SUPL initiation message is transmitted from a network entity to a SUPL entity, where the SUPL initiation message identifies a plurality of SUPL versions capable of supporting a desired service. A response is received from the SUPL entity that is based, at least in part, on an ability of the SUPL entity to support at least one of the plurality of versions.
Abstract:
Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for utilizing a reference signal for indoor positioning, such as for use in or with a mobile communication device, for example. In an implementation, a reference signal may be focused into a directed beam, for example using a phased antenna array, and rotated electronically through a sequence of directional angles in a horizontal plane. A mobile device may determine a most probable directional angle from one or more transmitters transmitting a directional beam, measure one or more parameters for each directional angle and determine a location estimate using, for example triangulation.
Abstract:
The subject matter disclosed herein relates in one particular implementation to a method, apparatus, and/or system for transmitting, by a location server, a location identifier to a mobile device. The location identifier may be transmitted from the mobile device to one or more trusted entities. Access to a location estimate of the mobile device may be selectively authorized at least partially in response to a request received at the mobile device from the location server including the location identifier.

Abstract:
A method of providing location services at a location server for a venue includes: receiving a request for location service, where the request for location service comprises at least one of a first identification of at least one mobile device or an identification of a target area; and sending a response, where the response comprises at least one of a second identification of at least one mobile device or an identification of a geographic area, where at least one of the first identification of at least one mobile device, the second identification of at least one mobile device, the identification of the target area, or the identification of the geographic area comprises a venue-specific identification.
Abstract:
Techniques to support positioning for access points and terminals in WLANs and other wireless networks are described. In one aspect, WLAN positioning is supported with Secure User Plane Location (SUPL). A terminal obtains measurements for an access point in a WLAN and/or receives measurements made by the access point for the terminal. The terminal determines WLAN AP information for the access point and/or the terminal based on the measurements and sends the WLAN AP information to a SUPL Location Platform (SLP). The SLP determines a location estimate for the terminal based on the WLAN AP information. In another aspect, the terminal receives supported network information from the SLP. The terminal obtains network measurement information (e.g., measurements) for a radio access network and determines which particular network measurement information to send based on the supported network information. The terminal sends network measurement information permitted by the supported network information to the SLP.
Abstract:
Techniques are presented for receiving, at a discovered secure user platform location (SUPL) server (D-SLP) a request from a device for authorization to access a second D-SLP, where the D-SLP provides location services to a first service area comprising a venue or building. The second D-SLP provides location services to a second service area larger than the first service area authenticating information from a Home SLP (H-SLP) received as part of the request to access the second D-SLP. Techniques involve communicating an authorization to access the second D-SLP to the device after authenticating the information from the H-SLP.
