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: Methods and apparatus for processing positioning assistance data are provided. An exemplary method includes receiving, from a positioning server, virtual access point (VAP) data including a list of unique identifiers, and determining a location of a mobile device by using the VAP. The VAP data indicates that the unique identifiers included on the list identify signals originating from the same physical access point. The unique identifiers can be MAC addresses. In an example, the location determining the can include actively scanning a signal identified by a unique identifier on the list and not actively scanning a different signal identified by a different unique identifier also on the list. Not scanning the other MAC addresses that are on the access point's list and assigned to the mobile device keeps the mobile device from performing duplicative scanning that wastes time, processor cycles, and energy.
