1. A communication system for facilitating control over a function of a vehicle, the communication system comprising:
- a base station positioned in the vehicle; and
a mobile communication unit;
the base station comprising a first transmitter for transmitting a signal to the mobile communication unit and a first receiver for receiving a signal from the mobile communication unit;
the base station being further configured to cause the mobile communication unit to operate in accordance with a limited-response duty cycle, and to cause the mobile communication unit to resume operating in accordance with a high-response duty cycle in response to an occurrence of a predetermined trigger event, wherein the predetermined trigger event comprises a user initiated interaction with the vehicle,wherein the limited-response duty cycle comprises a period of inactivity, during which the mobile communication unit is unable to receive a transmission from the base station, and a period of activity, during which the mobile communication unit is capable of receiving a transmission from the base station, andwherein the high-response duty cycle comprises a period of activity, during which the mobile communication unit is capable of receiving a transmission from the base station.
