Abstract

Determination of a current location of a mobile device based on exchange of messages between the mobile device and a remote device. The determination can be originated from the remote device and can be performed, in certain embodiments, by a system within a network that provides services to the mobile device. The location of the mobile device can be determined without reliance on a dedicated location service module (e.g., software or firmware) at the user equipment. The system can utilize signals from a global navigation satellite system or signals time-of-flight terrestrial signals emitted and/or received at the mobile device. In addition, the system can provide location information associated with the mobile device in response to a prompt from the remote device in instances in which the remote device is authorized to receive location information. An authorized remote device can be or can include a device associated with the user equipment or a third-party device.
