Systems and methods for providing updated mobile station location estimates to emergency services providers
First Claim
1. A system, comprising:
- a processor;
a computer-readable storage medium comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, for processing an emergency call between a wireless communication device and a public safety answering point, comprising;
detecting whether a triggering event associated with the emergency call has occurred, wherein the triggering event includes handover of the emergency call from a first subdivision of the wireless communication network to a second subdivision of the wireless communication network;
determining, in response to detecting that the triggering event has occurred, whether a triggering condition associated with the emergency call is satisfied, wherein the triggering condition includes a current value of a previously-initiated count-up timer being greater than a pre-determined threshold value; and
determining, in response to determining that the triggering condition is satisfied, whether an automatic provision of updated location estimates feature has been enabled for the public safety answering point.

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.

10. A system, comprising:
-
a processor; and a computer-readable storage medium comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, for processing an emergency call between a wireless communication device and a public safety answering point, comprising; detecting, by a component of a wireless communication network, whether a triggering event associated with the emergency call has occurred, wherein the triggering event includes handover of the emergency call from a first subdivision of the wireless communication network to a second subdivision of the wireless communication network; and determining, in response to detecting that the triggering event has occurred, whether a triggering condition associated with the emergency call is satisfied, wherein the triggering condition includes a current value of a previously-initiated count-up timer being greater than a pre-determined threshold value; wherein the pre-determined threshold value corresponds to a value distinguishing between; (I) insubstantial movement of the wireless communication device, wherein the wireless device is presumed to be moving rapidly in and out of subdivisions of the wireless communication network; and (II) substantial movement of the wireless communication device, wherein the wireless device is presumed to not be moving rapidly in and out of subdivisions of the wireless communication network. - View Dependent Claims (11, 12, 13, 14, 15)
