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.
