Abstract

Fixed devices may be distinguished from mobile devices in a broadband wireless network. Fixed devices may be given an identifier that identifies the device as a fixed device.

First claim

What is claimed is:

1. A method comprising:
automatically determining whether a device in a broadband wireless machine-to-machine network is a fixed device that never moves; and
in response to the determination that the device is a fixed device determining whether the device's identifier space can be expanded, and if so, increasing the identifier space, and assigning an identifier to indicate that the device is a fixed device using a message exchange over an air interface.

2. The method of claim 1 wherein automatically determining includes detecting whether the device moves.

3. The method of claim 1 wherein automatically determining includes analyzing a function of the device.

4. The method of claim 1 wherein automatically determining includes analyzing whether signal strength or received power changes by more than a threshold over a predetermined length of time.

5. The method of claim 1 wherein assigning includes checking for an available identifier.

6. The method of claim 1 wherein assigning includes checking for an available device type.

7. The method of claim 1 wherein assigning includes checking for an available temporary identifier.

8. The method of claim 1 wherein assigning includes determining whether it is possible to expand an identifier space.

9. The method of claim 1 wherein assigning includes determining whether a lifetime can be assigned to an identifier.

10. The method of claim 1 wherein assigning includes changing the way temporary identifiers are handled.

11. The method of claim 1 wherein assigning includes using time division multiplexing.

12. The method of claim 1 including analyzing activity on the device to determine if it is a fixed device.

13. A non-transitory computer readable medium storing instructions executed to:
determine whether a device in a broadband wireless machine-to-machine network is a fixed device that never moves; and
if the device is a fixed device determining whether the device's identifier space can be expanded, and if so, increasing the identifier space, and use a message exchange over an air interface to assign an identifier indicating that the device is a fixed device.

14. The medium of claim 13 further storing instructions to detect whether the device moves to determine if the device is a fixed device.

15. The medium of claim 13 further storing instructions to analyze a function of the device to determine if the device is a fixed device.

16. The medium of claim 13 further storing instructions to analyze whether signal strength or received power changes by more than a threshold over a predetermined length of time to determine if the device is a fixed device.

17. The medium of claim 13 further storing instructions to check for an available identifier, check for an available device type, check for an available temporary identifier, determine whether it is possible to expand an identifier space, or determine whether a lifetime can be assigned to an identifier.

18. The medium of claim 13 further storing instructions to change the way temporary identifiers are handled.

19. The medium of claim 13 further storing instructions to use time division multiplexing.

20. The medium of claim 13 further storing instructions to analyze activity on the device to determine if it is a fixed device.

21. An apparatus comprising:
a processor to determine whether a wireless machine-to-machine device is fixed or mobile, if the device is a fixed device to determine whether the device's identifier space can be expanded, and if so, increase the identifier space, assign an identifier to the device to indicate that the device is a fixed device that never moves, said identifier assigned using a message exchange over an air interface; and
a storage coupled to said processor.

22. The apparatus of claim 21 wherein said device is a server.

23. The apparatus of claim 21 wherein said processor to determine whether the device is fixed or not by detecting whether the device moves.

24. The apparatus of claim 21 wherein said processor to determine whether the device is a fixed device by analyzing a function of the device.

25. The apparatus of claim 21 wherein said processor to determine whether the device is a fixed device by analyzing signal strength on received power.

26. The apparatus of claim 21 wherein said processor to assign an identifier by checking for available identifiers, check for an available device type, checking for an available temporary identifier, or determine whether it is possible to expand an identifier space.

27. The apparatus of claim 21 wherein said processor to assign an identifier by determining whether a lifetime can be assigned to an identifier.

28. The apparatus of claim 21 , said processor to assign an identifier using time division multiplexing.

29. The apparatus of claim 21 including a touch screen.
