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 network;

separate from said authentication, transmission, by said public mobile network to said mobile terminal, of an authorization to initialize said link between said mobile terminal and said domestic base station, and of data specific for initializing said link; and

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

wherein said data specific for initializing includes time stamp information and initializing said link between said mobile terminal and said base station fails if the data specific for initializing is received beyond a given time period.

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

5. The method of claim 1 wherein said step of authentication of said mobile terminal includes transmission by said mobile terminal of information required for initializing said link.

6. The method as claimed in claim 5, wherein said information required for initializing said link comprises the type of the 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.

10. The method as claimed in claim 9, wherein said contactless link comprises at least one of an infrared link and a microwave link for contactless cards.

11. The method claimed in claim 1 wherein said domestic base station is a public switched network terminal.

12. The method of claim 1 wherein said domestic base station is a private automatic branch exchange terminal.

13. A service for managing 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 network; and

separate from said authentication, transmission, by said public mobile network to said mobile terminal, of an authorization to initialize said link between said mobile terminal and said domestic base station, and of data specific for initializing said link;

wherein said data specific for initializing includes time stamp information and initializing said link between said mobile terminal and said base station fails if the data specific for initializing is received beyond a given time period.

14. A service as claimed in claim 13 further including reception of a call from a mobile terminal before said authentication.

15. The service claimed in claim 13 wherein said link initialization data depends on the location of said mobile terminal during said authentication.

16. The service claimed in claim 13 wherein said authentication includes the normal authentication of said mobile terminal by said public mobile network.

17. The service claimed in claim 13 wherein said authentication of said mobile terminal includes transmission by said mobile terminal of information required for initialization of said link.

18. The service as claimed in claim 17, wherein said information required for said initialization of said link comprises the type of the domestic base station.

19. A method of transferring a cellular terminal of a cellular network to a domestic base station, comprising:

authenticating the cellular terminal by the cellular network;

transmitting, from the cellular network to the cellular terminal, an authorization to initialize a link between the cellular terminal and the domestic base station, and of management parameters specific for initializing said link; and

transferring the management parameters from the cellular terminal to the domestic base station;

wherein said management parameters specific for initializing includes time stamp information and transferring said cellular terminal to said base station fails if the management parameters specific for initializing are received beyond a given time period.

20. The method of claim 19, wherein, in the transmitting step, the management parameters are transmitted from the cellular network to the cellular terminal by an entity other than an operator of the cellular network.

21. The method of claim 19, wherein, after the transmitting step, the management parameters are stored on a smart card of the cellular terminal, and wherein, in the transferring step, the smart card is inserted into a smart card reader of the domestic base station.

22. The method of claim 19, wherein, in the transferring step, the management parameters are transferred from the cellular terminal to the domestic base station on a frequency different from the frequency of the link.

23. The method of claim 19, wherein the management parameters related to the link between the cellular terminal and the domestic base station are selected from the group consisting of frequencies, channels frequency variation law information, and maximal power information.

24. The method of claim 19, wherein, in the transmitting step, the management parameters transmitted from the cellular network to the cellular terminal depend on a location of the cellular terminal during the authentication step.

25. A service for managing a link between a cellular terminal of a cellular network and a domestic base station, comprising:

authenticating the cellular terminal by the cellular network; and

transmitting, from the cellular network to the cellular terminal, an authorization to initialize the link between the cellular terminal and the domestic base station, and of management parameters specific for initializing the link between the cellular terminal and the domestic base station;

wherein said management parameters specific for initializing includes time stamp information and transferring said cellular terminal to said base station fails if the management parameters specific for initializing are received beyond a given time period.

26. The service of claim 25, further comprising receiving a call from the cellular terminal before the authenticating step.

27. The service of claim 25, wherein, in the transmitting step, the management parameters transmitted from the cellular network to the cellular terminal depend on a location of the cellular terminal during the authentication step.

28. The service of claim 25, wherein, in the authenticating step, the cellular terminal transmits information regarding a type of the domestic base station to the cellular network.
