Abstract

A wireless device in a vehicle interfaces with an associated device having a user interface. A wireless circuit included in the wireless device establishes a communications link with a wireless network while the associated device functioning as an end terminal communicates with the network via the communications link. When the interface between the wireless device and associated device is disrupted, the wireless device intentionally disconnects the communications link with the wireless network.

Claims

1. An in-vehicle wireless device, through which an associated device is allowed to communicate with a wireless network,

the in-vehicle wireless device comprising:

a wireless circuit that establishes and disconnects a communications link with the wireless network;

an interface circuit that interfaces with the associated device; and

a control circuit that executes a determination of whether an interface is disrupted between the interface circuit and the associated device while the associated device functions as an end terminal for communications with the wireless network via a communications link established between the wireless circuit and the wireless network,

wherein, when the determination is affirmative, the control circuit causes the wireless circuit to disconnect the established communications link.

2. The in-vehicle wireless device of claim 1,

wherein, when the determination is affirmative, the control circuit causes the wireless circuit to disconnect the established communications link after duration of disruption of the interface reaches a predetermined time.

3. The in-vehicle wireless device of claim 1,

wherein no wireless function to establish and disconnect a communications link with the wireless network without using the wireless circuit is included in the associated device.

4. The in-vehicle wireless device of claim 1, wherein

the communications with the wireless network includes at least one of an audio communications and a data communications.

5. The in-vehicle wireless device of claim 1,

wherein no user interface for accepting a user instruction to disconnect the established communications link is comprised.

6. The in-vehicle wireless device of claim 1,

wherein the communications link between the wireless circuit and the wireless network is disconnected based on a user instruction, which is accepted by a user interface included in the associated device and sent to the wireless circuit via the interface circuit and the control circuit.

7. An in-vehicle wireless device, through which an associated device is allowed to communicate with a wireless network,

the in-vehicle wireless device comprising:

wireless means for establishing and disconnecting a communications link with the wireless network;

interfacing means for interfacing with the associated device; and

determining means for executing a determination of whether an interface is disrupted between the interfacing means and the associated device while the associated device functions as an end terminal for communications with the wireless network via a communications link established between the wireless means and the wireless network; and

controlling means for causing the wireless means to disconnect the established communications link when the executed determination is affirmative.

8. A method used in an in-vehicle wireless device, through which an associated device is allowed to communicate with a wireless network,

the in-vehicle wireless device including:

a wireless circuit that establishes and disconnects a communications link with the wireless network; and

an interface circuit that interfaces with the associated device,

the method comprising;

executing a determination of whether an interface is disrupted between the interface circuit and the associated device while the associated device functions as an end terminal for communications with the wireless network via a communications link established between the wireless circuit and the wireless network; and

causing the wireless circuit to disconnect the established communications link when the executed determination is affirmative.
