Abstract

In a method for transmitting and/or receiving signals for at least one first and one second different service, particularly having a large range in a vehicle, at least one first antenna 25′ transmits and/or receives signals for the at least one first or second service, depending on a detectable event, and an antenna module performs this method.

Claims

1. A method for transmitting and/or receiving signals for at least one first and one second different service, especially with a long range, in a vehicle,

the method comprising:

at least one of transmitting and receiving by an at least one first antenna signals as a function of a detectable event exclusively for the at least first or second service.

2. The method according to claim 1, wherein the result of a query as to whether an authorized person is in the vehicle is used as the detectable event.

3. The method according to claim 1, wherein in that signals of the at least one first or second service, of which the signals, as a function of the detectable event, are not transmitted and/or received via the first antenna, are transmitted and/or received via the second antenna.

4. The method according to claim 1, wherein in that the signals of the at least one first and second services essentially use the same frequency range.

5. The method according to claim 1, wherein a mobile telephone service is used as the first service and an access control system service is used as the second service, with the signals of the telephone service at least not being permanently transmitted and/or received via the first vehicle antenna if an authorized person is not located in the vehicle and the telephone service being permanently switched on when an authorized person is located in the vehicle.

6. The method according to claim 1, wherein a third service is connected to the at least one first antenna such that, on occurrence of a further detectable event the at least one first antenna exclusively transmits and/or receives signals for the third service.

7. The method according to claim 6, wherein an E-call service is used as the third service.

8. The method according to claim 1, wherein the detection of an accident occurring to the vehicle is used as the further detectable event.

9. An antenna module for carrying out a method for transmitting and/or receiving signals for at least one first and one second different service in a vehicle,

comprising at least one first antenna configured to at least one of:

transmit and receive signals as a function of a detectable event exclusively for the at least first or second service, a controllable switch which has at least one first and one second signal input for the first and second services, respectively and at least one first signal output which is connected or linked to the first antenna, wherein the controllable switch comprises at least one first switch position in which the first signal output is only connected to the first signal input and the least one second switch position in which the first signal output is only connected to the second signal input.

10. The antenna module according to claim 9, wherein the antenna module has a second antenna connected or coupled to a second signal output of the switch whereby, in a switch position of the switch, the first signal input is exclusively connected to the first antenna and the second signal input is exclusively connected to the second antenna.

11. The antenna module according to claim 9, wherein the controllable switch comprises a third signal input for a third available service, whereby the controllable switch also has a third switch position in which the first signal output is only connected to the third signal input.

12. The antenna module according to claim 9, wherein module for executing the third service is also connected via a coupling device to the first signal input, so that in the first switch position the first signal output is connected to the first signal input.

13. The antenna module according to claim 9, wherein the at least one first antenna is arranged externally.

14. The antenna module according to claim 10, wherein the second antenna is arranged internally.

15. The antenna module according to claim 9, wherein the antenna module is configured to use the result of a query as to whether an authorized person is in the vehicle as the detectable event.

16. The antenna module according to claim 9, wherein the antenna module is configured to transmit and/or receive signals of the at least one first or second service which, as a function of the detectable event, are not transmitted and/or received via the first antenna, via the second antenna.

17. The antenna module according to claim 9, wherein the signals of the at least one first and second services essentially use the same frequency range.

18. The antenna module according to claim 9, wherein the antenna module is configured to use a mobile telephone service as the first service and an access control system service as the second service, with the signals of the telephone service at least not being permanently transmitted and/or received via the first vehicle antenna if an authorized person is not located in the vehicle and the telephone service being permanently switched on when an authorized person is located in the vehicle.

19. The antenna module according to claim 9, wherein a third service is connected to the at least one first antenna such that, on occurrence of a further detectable event the at least one first antenna exclusively transmits and/or receives signals for the third service.

20. The antenna module according to claim 19, wherein an E-call service is used as the third service.
