1. A method of determining whether to disconnect a wireless communication link between a communication device disposed in a vehicle and a mobile device, comprising:
- determining, by a processor, whether the communication device is moving or not moving;
determining, by the processor, whether the mobile device has exited a proximity of the vehicle;
determining, by the processor, whether the mobile device is connected to a wireless local area network;
monitoring, by the processor, whether the communication device receives a signal from the mobile device during at least a predetermined time period after determining that the mobile device has exited the proximity of the vehicle or connected to a wireless local area network; and
disconnecting the wireless communication link only if the communication device is not moving and the mobile device has either exited the proximity of the vehicle or connected to a wireless local area network, and the communication device does not receive a signal from the mobile device during the predetermined time period.

9. A communication device configured for use in a vehicle, the communication device to communicate with a mobile device comprising a motion sensor that generates movement signals indicative of motion of the mobile device, a cellular network transceiver configured to wirelessly transmit signals to and receive signals from a cellular network, a short range transceiver configured to wirelessly transmit short range signals to and receive short range signals from a communication device disposed in the vehicle over a wireless communications link, and a processor configured to evaluate the movement signals;
-
the communication device comprising; a short range transceiver configured to wirelessly transmit short range signals to and receive short range signals from the mobile device over the wireless communications link, the short range signals from the mobile device having a parameter, and a processor that compares the parameter of the short range signals from the mobile device to a threshold to determine whether the mobile device is in the vehicle, wherein the communication device disconnects the wireless communications link based on a determination that the communication device is not moving, the mobile device has either exited a proximity of the vehicle or connected to a wireless local area network, and the communication device does not receive a signal from the mobile device during a predetermined time period after determining that the communication device is not moving and the mobile device has either exited the proximity of the vehicle or connected to a wireless local area network, the determination that the mobile device has exited the proximity of the vehicle being based on the comparison of the parameter of the short range signals from the mobile device to the threshold. - View Dependent Claims (10)

11. A communication device configured to provide hands-free telephone communications when operated with a mobile device in a vehicle, comprising:
-
an input device for receiving an audio or video signal from a user in the vehicle; a short range transceiver for wirelessly transmitting short range signals corresponding to the signals received by the input device to the mobile device over a wireless communications link and wirelessly receiving short range signals from the mobile device having a parameter; an output device for outputting signals corresponding to the short range signals received from the mobile device; a memory for storing instructions; and a processor configured to execute the instructions stored in the memory to disconnect the wireless communications link in response to determining that the communication device is not moving and the mobile device has exited a proximity of the vehicle, wherein the processor determines that the mobile device has exited the proximity of the vehicle by at least one of comparing the parameter of the short range signals from the mobile device to a threshold, receiving a short range signal from the mobile device indicating that the mobile device has exited the proximity of the vehicle, and receiving a short range signal from the mobile device indicating that the mobile device has connected to a wireless local area network, and wherein the processor determines that the communication device is not moving by at least one of receiving a signal from the input device that corresponds to a sound of a door of the vehicle closing, receiving the short range signal from the mobile device indicating that the mobile device has exited the proximity of the vehicle, receiving the short range signal from the mobile device indicating that the mobile device has connected to a wireless local area network, and comparing the parameter of the short range signals from the mobile device to the threshold. - View Dependent Claims (12, 13, 14, 15)
