US Patent 9456298 Device-to-device location awareness

During an ongoing wireless telephone call communication session between a pair of mobile devices, a local device responds to its user's activation of a virtual or actual button or key, or its user's verbal command, by automatically sending an over the air message (e.g., a SMS or text message or other network communication message) to the remote device. The message requests location information of the remote device. Upon obtaining location information from the remote device, a location of the remote device is automatically displayed on the local device. Other embodiments are also described and claimed.
