Abstract

In addition to other aspects disclosed, a portable base station requests assignment of a portion of a code space from a remotely located control station. The assignment is based upon the location of the portable base station. The portable base station is also capable of transmitting an identification signal using the assigned code space portion to uniquely identify the portable base station to one or more access terminals.

Claims

1. A method comprising:

a portable base station, requesting assignment of a portion of a code space by sending a message to a remotely located control station, the message includes information about the portable base station and originates from the portable base station, the message is absent information about other base stations, wherein the assignment is based, at least in part, upon the location of the portable base station.

2. The method of claim 1 in which the request from the portable base station includes data that represents the location of the portable base station.

3. The method of claim 1 in which the code space includes a sequence of pseudorandom numbers.

4. The method of claim 3 in which the assigned code space portion is defined by an offset associated with the sequence of pseudorandom numbers.

5. The method of claim 4 in which the offset is defined by a number of chips.

6. The method of claim 1 in which requesting the assignment is initiated by a predefined event.

7. The method of claim 6 in which the event includes powering up the portable base station.

8. The method of claim 6 in which the event includes the remotely located control station requesting the status of the portable base station.

9. The method of claim 1 in which the code space conforms to a Code Division Multiple Access (CDMA) standard.

10. The method of claim 1 in which the code space conforms to a Universal Mobile Telecommunication System (UMTS) standard.

11. A system comprising:

a portable base station to request assignment of a portion of a code space by sending a message to a remotely located control station, the message includes information about the portable base station and originates from the portable base station, the message is absent information about other base stations, wherein the assignment is based, at least in part, upon the location of the portable base station.

12. The system of claim 11 in which the portable base station provides the functionality of a radio node, a radio node controller and an access gateway.

13. The system of claim 11 in which the assignment is based upon the distance between the portable base station and another base station.

14. The system of claim 11 in which the remotely located control station includes a server to assign the code space portion.

15. The system of claim 11 in which the assignment request includes data that represents the location of the portable base station.

16. The system of claim 11 in which the code space includes a sequence of pseudorandom numbers.

17. The system of claim 16 in which the assigned code space portion is defined by an offset associated with the sequence of pseudorandom numbers.

18. The system of claim 17 in which the offset is defined by a number of chips.

19. The system of claim 11 in which the assignment is requested upon the occurrence of a predefined event.

20. The system of claim 19 in which the event includes powering up the portable base station.

21. The system of claim 19 in which the event includes the remotely located control station requesting the status of the portable base station.

22. The system of claim 11 in which the code space conforms to a Code Division Multiple Access (CDMA) standard.

23. The system of claim 11 in which the code space conforms to a Universal Mobile Telecommunication System (UMTS) standard.

24. A computer program product tangibly embodied in a non-transitory machine-readable storage medium to cause:

a portable base station to request assignment of a portion of a code space by sending a message to a remotely located control station, the message includes information about the portable base station and originates from the portable base station, the message is absent information about other base stations, wherein the assignment is based, at least in part, upon the location of the portable base station.

25. The computer program product of claim 24 in which the assignment request from the portable base station includes data that represents the location of the portable base station.

26. The computer program product of claim 24 in which the assigned code space includes a sequence of pseudorandom numbers.

27. The computer program product of claim 26 in which the assigned code space portion is defined by an offset associated with the sequence of pseudorandom numbers.

28. The computer program product of claim 27 wherein the offset is defined by a number of chips.

29. The computer program product of claim 24 wherein requesting the assignment is initiated by an event.

30. The computer program product of claim 29 wherein the event includes powering up the portable base station.

31. The computer program product of claim 29 wherein the event includes the remotely located control station requesting the status of the portable base station.
