Abstract

A wireless communication link between two communication devices is established. A communication signal for contacting a second communication device is emitted from a first communication device. The communication signal is a first type of wireless data communication. Communications that are configured to transmit and receive data according to a second type of data communication are activated in the first communication device. Upon receipt of the communication signal, communications that are able to transmit and receive data according to the second type of data communication are activated in the second communication device, and the communication link according to the second type of data communication is established.

Claims

1. A method for establishing a wireless communication link between two communication devices comprising emitting from a first communication device a communication signal for contacting a second communication device, the communication signal being of a first type of wireless data communication, activating in the first communication device communication means which are configured to transmit and receive data according to a second type of data communication, upon receipt of the communication signal, activating in the second communication device communication means which are configured to transmit and receive data according to the second type of data communication, and establishing the communication link according to the second type of data communication between the communication means of the first and second communication devices.

2. A method according to claim 1, further comprising after the establishment of the communication link according to the second type of data communication, refusing the communication signal emitted from the first type of wireless data communication form the first communications device by the second communication device.

3. A method according to claim 1 further comprising establishing a communication link according to the first type of data communication if a communication link according to the second type of data communication is not successfully established within a first period of time.

4. A method according to claim 3, further comprising inactivating the communication means for the second type of data communication if the communication link according to the second type of data communication is not established within the first period of time.

5. A method according to claim 1, further comprising displaying the type of communication link which has been established on at least one of the first and second communication devices.

6. A method according to claim 1, wherein at least the second communication device comprises stored information for contacting the first communication device with the second type of data communication.

7. A method according to claim 1, wherein the communication signal emitted by the first communication device with the first type of data communication comprises identification information for contacting the first communication device with the second type of data communication.

8. A method according claim 1, further comprising simultaneously with transmitting the communication signal according to the first type of wireless data communication, contacting the second communication device via the second type of data communication with the first communication device.

9. A method according claim 1, wherein the first and second communication devices are mobile communication terminals.

10. A method according to claim 9, wherein the first and second communication devices are portable telephones.

11. A method according to claim 1, wherein the communication signal of the first type of wireless data communication is a GSM signal.

12. A method according to claim 1, wherein the communication link according to the second type of data communication is a bluetooth audio link.

13. A wireless communication device comprising first communication means for emitting and receiving communication signals according to a first type of data communication and second communication means for emitting and receiving communication signals according to a second type of data communication, wherein in order to establish a communication link according to the second type of data communication with another communication device, the communication device further comprises controlling means which automatically activate the second communication means if a communication signal according to the first type of data communication is emitted from or received by the communication device.

14. A wireless communication device according to claim 13, wherein the wireless communication device is configured to inactivate the first communication means after the establishment of the communication link according to the second type of data communication with another communication device.

15. A wireless communication device according to claim 14, wherein the controlling means are configured to automatically inactivate the second communication means if the communication link according to the second type of data communication is not established within a first period of time.

16. A wireless communication device according to claim 13, further comprising display means on which the type of communication link which has been established is displayed.

17. A wireless communication device according to claim 14, further comprising storing means including identification information for contacting other communication devices with the second type of data communication.

18. A wireless communication device according to claim 13, further comprising storing means including identification information for contacting the wireless communication device by means of the second type of data communication wherein the identification information is transmitted via a communication signal according to the first type of data communication.

19. A wireless communication device according to claim 13, wherein the wireless communication device is a mobile communication terminal.

20. A wireless communication device according to claim 19, wherein the wireless communication device is a portable telephone.

21. A wireless communication device according to claim 13, wherein the first type of data communication is a GSM signal.

22. A wireless communication device according to claim 13, wherein the second type of data communication is a bluetooth audio link.

23. A wireless communication system comprising at least two communication devices according to claim 13.

24. A wireless communication system according to claim 23, wherein a communication link according to the first type of data communication is established between the two communication devices if a communication link according to the second type of data communication is not successfully established within a first period of time.
