Zusammenfassung:A method and apparatus can ascertain a location of a personal portable wireless communication device. Movement of the personal portable wireless communication device can be sensed using a plurality of movement sensors on the personal portable wireless communication device. Wireless network signal strengths can be measured by the personal portable wireless communication device. A location of the personal portable wireless communication device can be ascertained based on the sensed movement of the personal portable wireless communication device and the measured wireless network signal strengths through Bayesian filtering.
