Abstract: A method of associating environmental context with wireless access points is disclosed. In some embodiments, a method on a user equipment may comprise determining at least one environmental context associated with a subset of one or more Access Points (APs) visible to the UE at an estimated location of the UE. The at least one environmental context associated with the subset may be determined based on one or more of wireless measurements by the UE, and/or sensor measurements by the UE. Further, at least one AP cluster may be determined by clustering the subset of the one or more APs visible to the UE based on the at least one environmental context and the estimated location. Environmental context for APs may be crowdsourced and stored and provided to a UE as location assistance information to facilitate location determination and other functions.

Abstract: Embodiments of methods and apparatuses for peer discovery in transactional mobile applications are disclosed. In one embodiment, a method of peer discovery includes receiving from a server, at a first device, a meeting location and information for communication with a second device, obtaining a series of location data related to the second device, where the location data is based on a non-device-to-device positioning, determining whether to perform a direct device-to-device positioning with the second device using the meeting location and information for communication with the second device, performing a series of last-stretch direct device-to-device positioning measurements between the first device and the second device in response to a determination to perform the direct device-to-device positioning with the second device, and identifying the second device based on the series of last-stretch device-to-device positioning measurements between the first device and the second device.

Abstract: Methods and systems are disclosed for improving reliability in mobile device positioning. A mobile device generates position data for a device, receives a first access point position reliability state associated with the first access point, determines a reliability of the position data based on the first access point position reliability state and an estimated location of the first access point, determines a threshold reliability requirement of an application associated with the mobile device, compares the reliability of the position data to the threshold reliability requirement of the application, and provides the position data of the device based on the comparison. A network entity determines access point characteristics associated with an access point, generates a position reliability state for the access point, sends the position reliability state to a mobile device, receives position data associated with the mobile device, and determines a trustworthiness of the position data.
