Abstract

A method comprising determining a source bearer for data, determining address information; and processing said data in accordance with a determined source bearer and said determined address information.

Claims

1. A method comprising

determining a source bearer for data,

determining address information;

and

processing said data in accordance with a determined source bearer and said determined address information.

2. A method as claimed in claim 1, wherein said processing comprises checking said determined source bearer and said determined address information against a look up table.

3. A method as claimed in claim 1, wherein said processing comprises determining if said data is for a device which received said data in dependence on said determined source bearer and said determined address information.

4. A method as claimed in claim 1, wherein said processing comprises determining if said data is to be transmitted to another device in accordance with said determined source bearer and said determined address information.

5. A method as claimed in claim 4, wherein said processing comprises determining a gateway to which said data is to be transmitted.

6. A method as claimed in claim 5, wherein said gateway comprises a network address translator.

7. A method as claimed in claim 1, comprising receiving data via a plurality of different bearers.

8. A method as claimed in claim 1, said method being performed in user equipment.

9. A device comprising:

a memory arranged to store routing information comprising address information and source information, said source information identifying a bearer associated with said address information.

10. A device as claimed in claim 9, wherein said address information comprises address information associated with said device.

11. A device as claimed in claim 9, wherein said address information comprises a range of addresses.

12. A device as claimed in claim 9, wherein said memory is arranged to store gateway information.

13. A device as claimed in claim 9, wherein said gateway information is arranged to identify a network address translator.

14. A device as claimed in claim 12, wherein said memory is arranged to store gateway information for outgoing data from said device.

15. A device as claimed in claim 9, wherein said address information comprises bearer information for outgoing data from said device.

16. A device as claimed in claim 9, wherein a plurality of routing information is provided, at least one routing information comprising source information indicative that said bearer is any bearer.

17. A device as claimed in claim 9, wherein said source information comprises one of GPRS (General packet radio server) bearer, WLAN (wireless local area network) bearer, Bluetooth bearer and any bearer.

18. A device as claimed in claim 9, wherein said source information identifies a wireless bearer.

19. A device as claimed in claim 9, wherein said device is configured to have a plurality of different bearers concurrently.

20. A device as claimed in claim 9, wherein said destination information comprises an IPv4 (Internet Protocol version 4) private address.

21. A device as claimed in claim 9, wherein said device comprises user equipment.

22. A device as claimed in claim 9, wherein said device comprises a router.

23. A device as claimed in claim 9 wherein said memory is configured to store said information in a table

24. A device comprising:

Storage means arranged to store routing information comprising address information and source information, said source information identifying a bearer associated with said address information.

25. A system comprising:

a first network;

a second network; and

a device configured to store routing information comprising address information and source information, said source information identifying a bearer associated with said address information, said bearer being associated with one of said first and second networks.

26. A system as claimed in claim 25, wherein at least one of said first and second networks comprises a network address translator.

27. A system comprising:

a first network;

a second network;

a first device configured to store routing information comprising address information and source information, said source information identifying a bearer associated with said address information, said bearer being associated with one of said first and second networks, said first device being connectable to said first and second networks; and

a second device connectable directly only to said first network, wherein said second device is connectable to said second network via said first device.

28. A system as claimed in claim 27, wherein said first network comprises a server arranged to allocate an address for said second device.

29. A computer program comprising program code configured to perform, when the program is run on a computer or on a processor the following:

determining a source bearer for data, determining address information; and

processing said data in accordance with a determined source bearer and said determined address information.
