Abstract
System and method for submitting a location of a mobile device to a public service for providing emergency assistance are described. A mobile device can determine that a user is making an emergency call from the mobile device. The mobile device can then enable a location determination function of the mobile device and determine a location of the mobile device. The mobile device can determine the location in multiple attempts, including, in a first time window, attempting to determine a location with low uncertainty and, if the attempt fails, determining a location with high uncertainty in a second time window. The mobile device can then submit the location to a dispatcher through a mobile network operator.

19. A method comprising:
-
in response to a request to access a public service, obtaining, by a mobile device from a location subsystem of the mobile device, a first location estimate, the first location estimate being associated with a first uncertainty value and a first reliability value; determining by the mobile device that, within a first time threshold, the first uncertainty value does not satisfy a first uncertainty threshold or the first reliability value does not satisfy a first reliability threshold; in response to the determining, obtaining, by the mobile device from the location subsystem, a second location estimate, the second location estimate being associated with a second uncertainty value and a second reliability value; and in response to determining by the mobile device that, within a second time threshold, the second uncertainty value satisfies a second uncertainty threshold and the second reliability value satisfies a second reliability threshold, providing, by the mobile device, the second location estimate to the public service, wherein the second uncertainty threshold is lower than the first uncertainty threshold, and the second reliability threshold is lower than the first reliability threshold. - View Dependent Claims (20, 21, 22, 23, 24, 25)

26. A mobile device comprising:
-
one or more processors; and at least one non-transitory computer-readable medium storing instructions operable to cause the one or more processors to perform operations comprising; in response to a request to access a public service, obtaining, from a location subsystem of the mobile device, a first location estimate, the first location estimate being associated with a first uncertainty value and a first reliability value; determining that, within a first time threshold, the first uncertainty value does not satisfy a first uncertainty threshold or the first reliability value does not satisfy a first reliability threshold; in response to the determining, obtaining, from the location subsystem, a second location estimate, the second location estimate being associated with a second uncertainty value and a second reliability value; and in response to determining that, within a second time threshold, the second uncertainty value satisfies a second uncertainty threshold and the second reliability value satisfies a second reliability threshold, providing the second location estimate to the public service, wherein the second uncertainty threshold is lower than the first uncertainty threshold, and the second reliability threshold is lower than the first reliability threshold. - View Dependent Claims (27, 28, 29, 30, 31, 32)

33. At least one non-transitory computer-readable medium storing instructions operable to cause one or more processors to perform operations comprising:
-
in response to a request to access a public service, obtaining, by a mobile device from a location subsystem of the mobile device, a first location estimate, the first location estimate being associated with a first uncertainty value and a first reliability value; determining by the mobile device that, within a first time threshold, the first uncertainty value does not satisfy a first uncertainty threshold or the first reliability value does not satisfy a first reliability threshold; in response to the determining, obtaining, by the mobile device from the location subsystem, a second location estimate, the second location estimate being associated with a second uncertainty value and a second reliability value; and in response to determining by the mobile device that, within a second time threshold, the second uncertainty value satisfies a second uncertainty threshold and the second reliability value satisfies a second reliability threshold, providing, by the mobile device, the second location estimate to the public service, wherein the second uncertainty threshold is lower than the first uncertainty threshold, and the second reliability threshold is lower than the first reliability threshold. - View Dependent Claims (34, 35, 36, 37, 38)
