Abstract

To make it easier for a subscriber to operate a wireless phone and a transceiver in a vehicle, the transceiver transmits an identification to the wireless phone within a limited transmission and reception range. When the wireless phone receives this identification, it transmits its identification data to the transceiver to inscribe itself in the transceiver. Alternatively, the wireless phone transmits its identification data within a limited transmission and reception range, and the transceiver receives this identification data and that the wireless phone is inscribed (i.e., registered) with the transceiver. The transceiver acts as interface for calls to and from the wireless phone.

Claims

1. A method for operating a transceiver installed in a motor vehicle that communicates with a wireless phone and a communication network, said method comprising:

transmitting transceiver identification data to the wireless phone that is located within a limited transmission and reception range with respect to the transceiver; and

receiving telephone identification data that is transmitted by the wireless telephone in response to receiving said transceiver identification data and inscribing the wireless telephone with the transceiver in response to receiving said telephone identification data.

3. A method of

claim 1

, wherein said telephone identification data is transmitted by said wireless telephone based upon called Blue Tooth Standard technology at a carrier frequency of 2.4 GHz.

4. The method of

claim 3

, further comprising transmitting data between the transceiver and the communication network using a GSM compatible communication protocol.

2. A method for operating a transceiver installed in a motor vehicle that communicates with a wireless phone and a communication network, said method comprising receiving telephone identification data from the wireless phone within a limited transmission and reception range of the transceiver and inscribing the wireless telephone with the transceiver in response to receiving said telephone identification data.

5. A transceiver unit for a motor vehicle that communicates via a first wireless communication channel with a wireless telephone and communicates via a second wireless communication channel with a cellular telephone communication network, said transceiver comprising:

means for transmitting transceiver identification data over the first communication channel to the wireless phone;

means for receiving telephone identification data from the wireless phone over the first communication channel;

a cellular telephone transceiver that transmits and receives data over the second wireless communication channel.

6. The transceiver unit of

claim 5

, wherein said means for receiving telephone identification data includes means for receiving the telephone identification data that is encoded in accordance with the Blue Tooth Standard at a carrier frequency of 2.4 GHz.

7. The transceiver unit of

claim 5

, wherein said means for transmitting transceiver identification data includes means for transmitting the transceiver identification data encoded in accordance with the Blue Tooth Standard at a carrier frequency of 2.4 GHz.

8. The transceiver unit of

claim 5

wherein

said means for receiving telephone identification data includes means for receiving the telephone identification data that is encoded in accordance with the Blue Tooth Standard at a carrier frequency of 2.4 GHz;

and

said means for transmitting transceiver identification data includes means for transmitting the transceiver identification data encoded in accordance with the Blue Tooth Standard at a carrier frequency of 2.4 GHz.

9. The transceiver unit of

claim 8

, wherein said cellular telephone transceiver comprises a GSM transceiver.

10. The transceiver unit of

claim 8

, wherein said cellular telephone transceiver comprises a SIM card reader configured and arranged to receive a SIM card.

11. The transceiver unit of

claim 8

, wherein said wireless telephone comprises a SIM card reader configured and arranged to receive a SIM card.
