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 positioned in the vehicle; and
a mobile communication unit;
wherein the base station comprises 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;
wherein the base station is configured to determine a location of the mobile communication unit relative to the vehicle and to transmit a command to the mobile communication unit to cause the mobile communication unit to operate in accordance with a limited-response duty cycle when the location of the mobile communication unit relative to the vehicle remains within an authorization zone for a predetermined period of time and remains substantially unchanged for the predetermined period of time;
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; and
wherein the authorization zone is exterior to the vehicle and comprises a zone in which the communication system is configured to authorize operation of one or more vehicle functions.
