摘要： In one embodiment, an apparatus includes a receiver configured for receiving a response message from a tracked device in a wireless network, the response message transmitted in response to a provoking message having an identifier of the tracked device in a transmitter address field, and a processor for measuring at least one location related parameter, extracting the identifier of the tracked device from the response message and identifying the response message as a location tracking message based on information in the response message. A field of the response message includes the identifier of the tracked device copied from the provoking message and the transmitter address is not provided in another field of the response message.
