Patent ID: 7848769

Claim:
A method for providing updated location information for a wireless communication device during an emergency call between the wireless communication device and a public safety answering point (PSAP), the method comprising: establishing, over a wireless communication network, the emergency call between the wireless communication device and the PSAP; initializing a count-up timer; after initializing the count-up timer, detecting, at the wireless communication network, if a triggering event associated with the emergency call has occurred, wherein the triggering event includes handover of the emergency call from one subdivision of the wireless communication network to a new subdivision of the wireless communication network; after the detecting step, and if the handover is detected, determining if a triggering condition associated with the emergency call is satisfied, wherein the triggering condition includes a current value of the count-up timer being greater than a pre-determined threshold value; if the triggering condition is not satisfied, returning to the determining step; if the triggering condition is satisfied, determining whether an automatic provision of updated location estimates feature has been enabled for the PSAP, wherein the automatic provision of updated location estimates feature, when enabled, provides for provisioning of updated location estimates made to the PSAP automatically and not in response to a request for updated location estimate; if the automatic provision of updated location estimates feature has not been enabled for the PSAP, returning to the initializing step; and if an automatic provision of updated location estimates feature has been enabled for the PSAP: obtaining updated location information for the wireless communication device; and transmitting the updated location information to the PSAP.
