Abstract

An automobile communication system includes an outgoing communication controller that receives a communication from a first input source in a first operating mode and a second input source in a second operating mode. The system also includes an input selector that selects the first input source in the first mode and the second input source in the second mode and a mode selector operable by an automobile passenger that determines the operating mode. The system also includes an incoming communication controller that receives an incoming communication from a cellular phone and an output selector that provides an output of the incoming communication controller to a first output device in the first operating mode and to the second output device in the second mode.

Claims

1. An automobile communication system in an automobile comprising:

an outgoing communication controller that receives a communication from a cellular telephone in a first operating mode and a microphone separate from the cellular telephone in a second operating mode;

an input selector that selects the cellular telephone in the first operating mode and the microphone in the second operating mode;

a mode selector operable by an automobile passenger that receives an indication from the automobile passenger during a cellular telephone call indicating a change from the second operating mode to the first operating mode is desired;

an incoming communication controller that receives an incoming communication from the cellular telephone; and

a button in the car causes an output of the incoming communication controller to the cellular telephone in the first operating mode and to a speaker in the automobile in the second mode.

2. The system of claim 1, further comprising:

a personal area network (PAN) receiver coupled between the microphone and the outgoing communication controller and between the cellular telephone and the incoming communication controller.

3. The system of claim 2, further comprising:

a PAN transmitter coupled between the outgoing communication controller and the cellular telephone and between the incoming communication controller and the second input source.

4. The system of claim 3, further comprising:

the cellular telephone.

5. The system of claim 3, wherein the PAN transmitter is a Bluetooth transmitter and the PAN receiver is a Bluetooth receiver.

6. A method of switching from a handsfree public call to a handsfree private call in an automobile having a personal area network (PAN), the method comprising:

pairing a headset and a handset to the personal area network;

allowing a telephone call to begin in a handsfree public mode wherein incoming communications are replayed on an automobile speaker;

receiving an indication from a passenger in the automobile to change to a handsfree private mode during the telephone call without manipulating the headset; and

continuing the telephone call in a handsfree private mode wherein incoming communications are replayed on the headset.

7. The method of claim 6, wherein the personal area network is formed by a management module that includes a PAN receiver and a PAN transmitter.

8. The method of claim 6, wherein continuing includes receiving outgoing communications from the headset.

9. The method of claim 6, wherein allowing includes receiving outgoing communications from a microphone located in the automobile.

10. The method of claim 6, wherein receiving does not include receiving any indication that a user manipulated the handset.

11. The method of claim 6, further comprising:

re-allowing, after continuing, the telephone call to continue in the handsfree public mode wherein incoming communications are replayed on an automobile speaker.
