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: Method, device, computer program product, and apparatus to enable mobile device position optimization and reporting are described. Signals provided by a plurality of base transceiver stations (BTS) are received to determine a BTS-based position of the mobile device. A reference position of the mobile device is determined. A range measurement with respect to a target BTS is determined. In one aspect, one or more unreliable BTSs may be detected and reported based on a positioning measurement quality, a range measurement quality, or combinations thereof. In one aspect, the positioning measurement quality is determined based on a difference between the reference position of the mobile device and the BTS-based position of the mobile device. In one aspect, the range measurement quality is determined based on a difference between a measured range/distance and a reference/expected range/distance.

Abstract: Various methods, apparatuses and articles of manufacture are provided for use by one or more electronic devices to detect and/or respond to certain changes (anomalies) within a wireless signaling environment. For example, a first electronic device may receive a report of a threshold anomaly detected by a monitoring device deployed at a fixed predetermined position within a coverage area of a network service device, and may initiate an investigation by requesting that a second electronic device attempt to monitor certain transmissions of and/or actively communicate with a network service device. In response to a determination based, at least in part, on the investigation that the threshold anomaly represents a threshold change in status within the wireless signaling environment, the first electronic device may transmit a status report regarding the wireless signaling environment to another electronic device.

Abstract: A method for generating a radio coverage map. A two-dimensional radio coverage map located between a first physical level and a second physical level is generated. The access point is located above the second physical level. The two-dimensional radio coverage map is located at a distance from the access point and comprises a plurality of map points, where the map points have a predicted received signal strength value. A projection window is determined. A projected area on the two-dimensional radio coverage map is determined by computing a geometrical projection from the access point through the projection window onto the two-dimensional radio coverage map. A plurality of first points in a first area on the two-dimensional radio coverage map is identified. The first area is outside the projected area. The predicted received signal strength value of each of the first points is reduced by a value equal to the signal attenuation caused by the second physical level.
