Abstract
A wireless communication system, including apparatuses and methods, for handling emergency calls from wireless communication devices to emergency services providers and for automatically providing updated location estimates for the wireless communication devices to during such emergency calls absent any request therefor. The updated location estimates are generally provided in response to a detected occurrence of a triggering event within the wireless communication system. In the exemplary embodiments, such triggering events include the passage of a pre-determined threshold period of time and the handover of an emergency call between cells or sectors of the wireless communication system in response to movement of the wireless communication device from which the emergency call is being made. Further, according to at least one exemplary embodiment, the wireless communication system may selectively limit the provision of updated location estimates based on whether movement of a wireless communication device is substantial or insubstantial.
