METHOD AND SYSTEM FOR ADAPTIVE LOCATION DETERMINATION FOR MOBILE DEVICE
First Claim
1. A method comprising:
- receiving a first request by a user equipment (UE) device from a call center to determine a location of the UE device when the UE device is in an indoor environment; and
receiving a second request by the UE device from the call center to determine another location of the UE when the UE device is in an outdoor environment;
in response to the first request,determining the location by a) using a Mobile Station Based Assisted Global Positioning System (MSB AGPS) or b) detecting a pilot beacon inside a building, and in response to the second request;
determining the location using a standalone GPS.

Abstract
An example method includes connecting to a call center by a user equipment (UE) device via a voice call and receiving a request for a current location. The device is determined to be in an outdoor environment if the signal strength of satellite signals used by a global positioning system (GPS) is greater than a threshold. The device is determined to be in an indoor environment if a beacon signal strength is greater than a further threshold. If the device is in an outdoor environment, the current location is determined using a standalone or assisted GPS method. If the device is in an indoor environment, the current location is the known location of the beacon or an assisted GPS method. If neither the signal strength of the satellite signals nor the signal strength of the beacon exceeds its respective threshold, the current location is determined as a last stored location.

7. A user equipment (UE) device comprising:
-
at least one network interface, configured to support connection via a communication network; and a processor coupled to the network interface configured to cause the UE device to perform functions, including functions to; receive a first request from a call center to determine a location of the UE device, when the UE device is in an indoor environment; and receive a second request from the call center to determine another location of the UE device, when the UE device is in an outdoor environment; in response to the first request, determine the location by using, in the indoor environment, at least one of a) a Mobile Station Based Assisted Global Positioning System (MSB AGPS) or b) a pilot beacon, and in response to the second request, determine the other location using, in the outdoor environment, a standalone GPS. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A mobile device, comprising:
-
a processor; a first wireless transceiver coupled to the processor and configured to enable communications via a wireless communication network; a second wireless transceiver coupled to the processor and configured to enable communications with one or more local pilot beacons; and a memory storing programming instructions, wherein execution of the programming instructions by the processor configures the mobile device to perform functions, including functions to; upon determining that a predetermined condition is met, determine a location of the mobile device by performing functions to; determine whether a signal from a local pilot beacon is received using the second wireless transceiver; and upon determining that a signal from one local pilot beacon is received, determine the location of the mobile device to be the location of the one local pilot beacon from which the signal is received. - View Dependent Claims (16, 17, 18, 19)
