Abstract

A method is provided for connecting a wireless local network (WLAN) to a UMTS terminal station (ME) having USIM/USAT functionality, including the following method steps: monitoring the activity of the local network via the terminal station; transmitting the type and/or identity number of the local network to the terminal station once the activity of the local network has been successfully detected; initiating a logical link between the local network and the terminal station, and; querying the specific subscriber data of the local network. In an embodiment of the present invention, the temporary status of the local network and/or specific subscriber data of the local network are/is queried at periodic intervals.

Claims

1-15. -15. (canceled)

16. A method for connecting a wireless local network to a UMTS terminal station having USIM/USAT functionality, the method comprising:

monitoring activity of the wireless local network by the terminal station;

transmitting at least one of a type and an identity number of the wireless local network to the terminal station following successful detection of local network activity;

initiating a logical connection between the wireless local network and the terminal station; and

polling specific subscriber data of the wireless local network.

17. A method for connecting a wireless local network to a UMTS terminal station as claimed in claim 16, wherein a temporary status of at least one of the wireless local network and the specific subscriber data of the wireless local network is polled at periodic intervals.

18. A method for connecting a wireless local network to a UMTS terminal station as claimed in claim 16, wherein the specific subscriber data of the wireless local network includes a type/identity number, a subscriber identification, a password, a secret key for data encryption and decryption, and an address of an access node.

19. A method for connecting a wireless local network to a UMTS terminal station as claimed in claim 16, wherein the steps of monitoring and transmitting are initiated by a universal chip card installed in the terminal station.

20. A method for connecting a wireless local network to a UMTS terminal station as claimed in claim 19, wherein the terminal station notifies the universal chip card of a deactivation of the wireless local network.

21. A method for connecting a wireless local network to a UMTS terminal station as claimed in claim 20, wherein the universal chip card initiates a cleardown of the logical connection between the wireless local network and the terminal station.

22. A method for connecting a wireless local network to a UMTS terminal station as claimed in claim 16, wherein the terminal station acknowledges all data transmitted.

23. A data system for connecting a wireless local network to a UMTS terminal station, comprising:

a wireless local network;

a UMTS terminal station having USIM/USAT functionality and being suitable for establishing a connection to the wireless local network;

parts for monitoring activity of the wireless local network, the parts for monitoring being contained in the terminal station;

parts for transmitting at least one of a type and an identity number of the wireless local network to the terminal station, the transmission occurring following successful detection of local network activity;

parts for initiating a logical connection between the wireless local network and the terminal station; and

parts for polling specific subscriber data of the wireless local network.

24. A data system for connecting a wireless local network to a UMTS terminal station as claimed in claim 23, wherein the terminal station is suitable for polling a temporary status of at least one of the wireless local network and the specific subscriber data of the wireless local network at periodic intervals.

25. A data system for connecting a wireless local network to a UMTS terminal station as claimed in claim 23, wherein the specific subscriber data includes a type/identity number, a subscriber identification, a password, a secret key for data encryption and decryption, and an address of an access node.

26. A data system for connecting a wireless local network to a UMTS terminal station as claimed in claim 23, wherein the terminal station further comprises a universal chip card which initiates the monitoring of the activity of the wireless local network and the transmission of data to the terminal station.

27. A data system for connecting a wireless local network to a UMTS terminal station as claimed in claim 26, wherein the terminal station is suitable for notifying the universal chip card of a deactivation of the wireless local network.

28. A data system for connecting a wireless local network to a UMTS terminal station as claimed in claim 27, wherein the universal chip card is suitable for initiating a cleardown of the logical connection between the wireless local network and the terminal station.

29. A data system for connecting a wireless local network to a UMTS terminal station as claimed in claim 23, wherein the terminal station is suitable for acknowledging all data transmitted.

30. A UMTS terminal station having USIM/USAT functionality and being suitable for establishing a connection to a wireless local network, comprising:

parts for monitoring activity of the wireless local network;

parts for initiating transmission of at least one of a type and an identity number of the wireless local network to the terminal station, the transmission occurring following successful detection of local network activity;

parts for initiating a logical connection between the wireless local network and the terminal station; and

parts for polling specific subscriber data of the wireless local network.
