Abstract

A network has a central entity connected to a plurality of capillary networks and external networks. Information regarding the capillary networks and the external networks may be fused in the central entity to provide assistance services and network control to one or more of the capillary networks. The information may be collected from the capillary networks using a logical interface with a common upper layer coupled to multiple Radio Access Technologies (RATs). The central entity configures an internal communications network including a plurality of disparate devices, and recognizes and communicates with each device within the internal communications network by discovering each new device as introduced into the internal communications network. A communication link can be set up with reconfigurable or capable devices to exchange information possibly in another format in another band. The same communication link can be torn down after completion of the service.

Claims

1. A central entity for connecting a wireless transmit receive unit (WRTU) to an external network, comprising:

a processor, configured to;

send discovery signals via a plurality of Radio Access Technology (RAT) frequencies to discover the WTRU,

detect a RAT associated with the WTRU, provided that if the central entity is missing the RAT, the central entity is configured to download and install an instruction set corresponding to the RAT, and

establish a data link with the WTRU.

2. The central entity of claim 1, wherein the central entity is configured to send control information on a common control channel via different RATs at different times.

3. The central entity of claim 1, wherein the central entity is configured to discover the WTRU by receiving a beacon request that the WTRU transmits.

4. The central entity of claim 1, wherein the central entity is configured to simultaneously discover multiple WTRUs.

5. The central entity of claim 1, wherein the central entity is configured to receive an association and authentication request from the WTRU.

6. The central entity of claim 1, wherein the central entity is configured to send a teardown request signal to the WTRU after data transfer.

7. The central entity of claim 1, wherein the central entity is configured to prevent the Reduced Reconfigurable Gateway (RRG) from directly accessing the external network.

8. The central entity of claim 1, wherein the central entity is configured to use a first RAT to discover the WTRU, and a second RAT (different from the first RAT) to establish the data link.

9. The central entity of claim 8, wherein the central entity is configured to send a disassociation signal to the WTRU for the first RAT.

10. The central entity of claim 9, wherein the central entity is configured to send a re-association signal to the WTRU for the first RAT.

11. A method of using a central entity for connecting a wireless transmit receive unit (WRTU) to an external network, comprising:

sending discovery signals from the central entity via a plurality of Radio Access Technology (RAT) frequencies to discover the WTRU,

detecting a RAT associated with the WTRU, provided that if the central entity is missing the RAT, the central entity is configured to download and install an instruction set corresponding to the RAT, and

establishing a data link with the WTRU.

12. The method of claim 11, further comprising sending control information on a common control channel via different RATs at different times.

13. The method of claim 11, further comprising actively discovering the WTRU.

14. The method of claim 11, further comprising passively discovering the WTRU.

15. The method of claim 11, further comprising receiving an association and authentication request from the WTRU.

16. The method of claim 11, further comprising sending a teardown request signal to the WTRU after data transfer.

17. The method of claim 11, further comprising varying both RATs and operational frequencies during data link communication.

18. The method of claim 11, further comprising using a first RAT to discover the WTRU, and using a second RAT (different from the first RAT) to establish the data link.

19. The method of claim 18, further comprising sending a disassociation signal to the WTRU for the first RAT.

20. The method of claim 19, further comprising sending a re-association signal to the WTRU for the first RAT.
