Abstract

A method of initializing a link between a mobile terminal of a public mobile network and a domestic base station, for example a public switched network base station, comprises authentication of the mobile terminal by the public mobile network, transmission of data for initializing the link with the domestic base station to the terminal from the public mobile network and transmission of the data from the mobile terminal to the domestic base station. The public mobile network operator can therefore manage the channels used by the mobile terminal for the link with the domestic base station. The method further assures authentication that is as secure as that of the public mobile network.

Claims

1. A method of initializing a link between a mobile terminal of a public mobile network and a domestic base station, comprising:

authentication of said mobile terminal by said public mobile network,

transmission of data for initializing said link with said domestic base station to said terminal from said public mobile network, and

transmission of said data from said mobile terminal to said domestic base station.

2. A method as claimed in

claim 1

further comprising a step of said mobile terminal calling a special service number before said authentication step.

3. The method claimed in

claim 1

wherein said link initialization data depends on the location of said mobile terminal during said authentication step.

4. The method claimed in

claim 1

wherein said initialization data includes time information.

5. The method claimed in

claim 1

wherein said authentication step includes the normal authentication of said mobile terminal by said public mobile network.

6. The method claimed in

claim 1

wherein said step of authentication of said mobile terminal includes transmission by said mobile terminal of information required for initializing said link, such as the type of domestic base station.

7. The method claimed in

claim 1

wherein said step of transmitting data from said mobile terminal includes the storage of said initialization data in a smart card of said mobile terminal and insertion of said smart card into a card reader of said domestic base station.

8. The method claimed in

claim 1

wherein said step of transmitting data from said mobile terminal includes the transmission of data from said mobile terminal to said base station over a link separate from the link to be set up.

9. The method claimed in

claim 8

wherein said separate link is a contactless link such as an infrared link or a microwave link for contactless cards.

10. A method as claimed in

claim 8

including a step of authorizing data transfer before said step of transmitting data from said mobile terminal.

11. The method claimed in

claim 1

wherein said domestic base station is a public switched network terminal.

12. The method claimed in

claim 1

wherein said domestic base station is a private automatic branch exchange terminal.

13. A service for management of links between mobile terminals of a public mobile network and domestic base stations, comprising:

authentication of a mobile terminal by said public mobile network, and

transmission of data for initializing a link with a domestic base station to said terminal from said public mobile network.

14. A service as claimed in

claim 13

further including a step of receiving a call from a mobile terminal before said authentication step.

15. The service claimed in

claim 13

wherein said link initialization data depends on the location of said mobile terminal during said authentication step.

16. The service claimed in

claim 13

wherein said initialization data includes time information.

17. The service claimed in

claim 13

wherein said authentication step includes the normal authentication of said mobile terminal by said public mobile network.

18. The service claimed in

claim 13

wherein said step of authentication of said mobile terminal includes transmission by said mobile terminal of information required for initialization of said link, such as the type of domestic base station.

19. A domestic base station comprising a smart card reader.

20. A cordless telephone system comprising a domestic base station, a mobile terminal and a link between said base station and said terminal separate from the telephone link.

21. The system claimed in

claim 20

wherein said separate link is a contactless link such as an infrared link or a microwave link for contactless cards.
