Abstract

A wireless intranet office (WIO) concept is disclosed, which integrates an IP based Intranet environment (27) and GSM network providing mobile telephones (21) with access to GSM through the GSM network or via the intranet. Access through the intranet to the GSM MSC (26) is provided by a WIO interworking unit (24) which may comprise several network entities (e.g. intranet mobile cluster (241), intranet location register (242), WIO gatekeeper (243), WIO gateway (244) and H.323 gateway). A dual mode terminal for such a system is also disclosed.

Claims

1. A dual mode mobile station comprising:

managing means for managing information independently of the mode of operation of the mobile station;

first linking means for linking to the interface of a mobile communication network, said first linking means comprising a radio resource manager for the mobile communication network;

second linking means for providing a link to the interface of a further communication network, said second linking means comprising a radio resource manager for the further communication network; and

means for coupling the managing means to the first linking means when the mobile station is in a first mode and to the second linking means when the mobile station is in the second mode such that the mobile station remains connected to the mobile communication network, while actual data is carried over the further communication network.

2. A mobile station as claimed in claim 1, wherein the managing means further manages radio resources information independently of the mode of operation of the mobile station.

3. A mobile station as claimed in claim 1, wherein the second linking means comprises a low power RF radio resource.

4. A mobile station as claimed in claim 3, wherein the low power RF is Bluetooth.

5. A mobile station as claimed in claim 2, wherein the radio resource management is that the mobile communication network.

6. A mobile station as claimed in claim 1, wherein the call control and mobility management is that of the mobile communication network.

7. A mobile station as claimed in claim 1, wherein the mobile communication network is GSM.

8. A mobile station as claimed in claim 1, further comprising a radio resource manager for a user terminal, and linking means for linking to the interface of the terminal device so as to transfer radio resource information between the mobile station and the user terminal.

9. A mobile station as claimed in claim 1, further comprising a browser.

10. A dual mode station comprising:

control means for controlling transfer of information such that in a first mode transfer of information is between the mobile station and a mobile communication network, and in a second mode transfer of information is between the mobile station and a second communication network; and

means for providing radio contact between the mobile station and the mobile communication network in both the first and second modes.

11. A method for controlling transfer of information in a communication system comprising a mobile communication network and a second communication network and a dual mode mobile station capable of communicating with both of said networks, the method comprising:

providing a first communication link to the interface between the mobile station and the mobile communication network, said first communication link including radio resource management of the mobile communication network;

providing a second communication link to the interface between the mobile station and the second communication network, said second communication link including radio resource management of the second communication network; and

maintaining said first communication link such that the mobile station remains connected to the mobile communication network, while actual data is carried over the second communication network.

12. A method as claimed in claim 11, further comprising:

managing radio resources information independently of the mode of operation of the mobile station.

13. A method as claimed in claim 11, further comprising:

providing the second communication link as a low power RF radio resource.

14. A method as claimed in claim 13, wherein the low power RF is Bluetooth.

15. A method as claimed in claim 11, further comprising:

providing call control and mobility management of the mobile station via the mobile communication network.

16. A communication system comprising a mobile communication network and a second communication network and a dual mode mobile station capable of communicating with both of said networks, wherein:

the mobile communication network comprises a base transceiver station emulator for providing a first communication link to the interface between the mobile station and the mobile communication network, said first communication link including radio resource management of the mobile communication network;

the second communication network comprises a second base transceiver station for providing a second communication link to the interface between the mobile station and the second communication network, said second communication link including radio resource management of the second communication network; and

the mobile communication network comprises controlling means for maintaining said first communication link such that the mobile station remains connected to the mobile communication network, while actual data is carried over the second communication network.

17. A communication system as claimed in claim 16, wherein the mobile communication network comprises managing means for managing radio resources information independently of the mode of operation of the mobile station.

18. A communication system as claimed in claim 16, wherein the second communication link is a low power RF radio resource.

19. A communication system as claimed in claim 18, wherein the low power RF is Bluetooth.

20. A communication system as claimed in claim 16, wherein call control and mobility management of the mobile station is managed via the mobile communication network.
