receiving a plurality of audio signatures simultaneously transmitted from a head unit, wherein said plurality of audio signatures are received via an audio system having a plurality of speaker channels and further wherein each of said plurality of audio signatures comprises a single beep per speaker channel that is separately detectable in an out-of-hearing frequency band of a signal recorded by a microphone of said wireless UE device; and
processing said plurality of audio signatures, by a processor of said wireless UE device configured to operate in association with one or more subsystems of said wireless UE device, for determining said wireless UE device's location relative to a particular spatial configuration associated with the interior of a vehicle, wherein said processing is facilitated by:
receiving an encoded vehicle information signal from said head unit via at least one of said plurality of speaker channels,
decoding said encoded vehicle information signal to obtain an identity of the vehicle in which said head unit is implemented, and
correlating said identity with a database to determine said particular spatial configuration.
estimating said wireless UE device's location based on said plurality of said time delays relative to said particular spatial configuration.
3. The method of claim 1 wherein said out-of-hearing frequency band comprises a frequency range beyond 18 kHz.
6. The method of claim 1 further comprising deactivating at least a functionality of said wireless UE device based on said wireless UE device's location relative to said particular spatial configuration.
8. A wireless user equipment (UE) device comprising:
a persistent memory module having program instructions which, when executed by said processor, perform: facilitating reception of a plurality of audio signatures from a head unit via an audio system having a plurality of speaker channels, wherein said plurality of audio signatures are simultaneously transmitted from the head unit and further wherein each of said plurality of audio signatures comprises a single beep per speaker channel that is separately detectable in an out-of-hearing frequency band of a signal recorded by a microphone of the wireless UE device, and processing said plurality of audio signatures, by the processor operating in association with one or more subsystems of the wireless UE device, for determining said wireless UE device's location relative to a particular spatial configuration associated with the interior of a vehicle, wherein said processing is facilitated by:
9. The wireless UE device of claim 8 wherein said persistent memory module further comprises program instructions for deactivating at least a functionality of said wireless UE device based on said wireless UE device's location relative to said particular spatial configuration.
