Method and system for adaptive location determination for mobile device

摘要

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.

主权项

1. A method comprising:
receiving, by a user equipment (UE) device from a call center, a first request to determine a location of the UE device when the UE device is in an indoor environment; and receiving, by the UE device from the call center, a second request 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 whether the UE device is currently in use in a voice call communication; andupon determining that the UE device is currently in use in the voice call communication, determining the other location using a standalone GPS.
