Abstract
Measurements from a plurality of Access Points (APs) may be used to determine that at least one AP in the plurality is mobile. Measurements from APs determined to be mobile may be excluded when determining a User Equipment (UE) location. Disclosed embodiments also pertain to AP mobility characterization. AP mobility may be determined based on range rate measurements such as Round Trip Time measurements between the AP and UE; or a Doppler frequency shift relative to a nominal frequency used by the AP for transmissions. Based on range rate measurements, a probability of mobility may be assigned to APs. Information pertaining to APs that are determined to be stationary or associated with a low probability of mobility may be reported to a location server. Information pertaining to APs determined to be mobile or associated with a higher probability of mobility may not be reported to a location server.
