Patent ID: 8779970

Claim:
A method of identifying an estimated location of a mobile device, comprising: receiving a first wireless communication signal of a first type; receiving a second wireless communication signal of a second type, the second type differing from the first type; determining a first candidate location of the mobile device and a first accuracy metric based on a signal strength of the first wireless communication signal; determining a second candidate location of the mobile device and a second accuracy metric based on the second wireless communication signal, the second accuracy metric being of a different type from the first accuracy metric, where the second accuracy metric is associated with a feature of the second wireless communication signal other than signal strength; normalizing the first accuracy metric that is based on signal strength of the first wireless communication signal with the second accuracy metric of the different type from the first accuracy metric; and determining an estimated location of the mobile device based on the first candidate location, the normalized first accuracy metric, the second candidate location, and the normalized second accuracy metric, the estimated location being determined using a weighted average of the first candidate location and the second candidate location, where weights of the weighted average are based on the normalized first accuracy metric and the normalized second accuracy metric.
