POSITION-BASED LIMITED-RESPONSE MODE OPERATION IN A VEHICLE COMMUNICATION SYSTEM
First Claim
1. A communication system for facilitating control over a function of a vehicle, the communication system comprising:
- a base station; and
a mobile communication unit comprising a motion sensor configured to detect movement of the mobile communication unit and to output a signal indicative of the movement;
wherein the base station comprises a first transmitter configured to transmit a signal to the mobile communication unit and a first receiver configured to receive a signal from the mobile communication unit;
wherein the base station is configured to determine a location of the mobile communication unit relative to the vehicle and to cause the mobile communication unit to operate in accordance with a limited-response mode when the location of the mobile communication unit relative to the vehicle remains substantially unchanged for a predetermined period of time.
