Abstract
The present invention is a system and method for tracking movement of a wireless device. The tracking can be done during a wireless communication session between the wireless device and a called party. The present invention comprises a location system that can generate initial location information pinpointing an initial location of the wireless device. The location system can generate subsequent location information pinpointing subsequent locations of the wireless device. The system further comprises a location server that can determine whether the subsequent location information should be provided to the called party in accordance with a rule. Based on the subsequent location information, the movement of the wireless device can be tracked by the called party. In the preferred embodiment, the wireless device is a wireless telephone and the called party is a public safety answering point. In the preferred embodiment, the subsequent location can be generated at regular intervals, and the subsequent location can be provided to the public safety answering point when the subsequent location information indicates that the wireless device has traveled a specific distance.
