Abstract

A paging frame may be determined from a combination of a first value divided by a second value and a WTRU identifier modulo the second value. The WTRU identifier may be related to an international mobile subscriber identification (IMSI) value of the WTRU.

Claims (45)

1. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:

determining, by a processor of the WTRU, a paging frame, wherein the paging frame is determined from a combination of a first value divided by a second value that is based on a discontinuous reception (DRX) cycle value of the WTRU and a WTRU identifier modulo the second value;

monitoring, by the WTRU, transmissions from a network for paging information based on the paging frame; and

wherein the WTRU identifier is related to an international mobile subscriber identity (IMSI) value of the WTRU.

2. The method of claim 1 , wherein the first value is the IMSI of the WTRU.

3. The method of claim 1 , wherein the WTRU identifier is equal to the IMSI.

4. The method of claim 1 , wherein the second value is equal to the DRX cycle value of the WTRU.

5. The method of claim 1 , wherein the WTRU is a long term evolution (LTE) WTRU.

6. The method of claim 1 , wherein the paging frame is referenced to a system frame number.

7. The method of claim 1 further comprising:

determining paging occasions based on the determined paging frame.

8. The method of claim 1 , wherein the WTRU is in an idle mode.

9. The method of claim 1 , wherein the WTRU is in DRX in frames other than those related to the paging frame.

10. The method of claim 1 , wherein the DRX cycle value of the WTRU is different than DRX cycle values of other WTRUs.

11. The method of claim 1 , wherein the combination is an addition operation.

12. A wireless transmit/receive unit (WTRU) comprising:

at least one processor configured to determine a paging frame, wherein the paging frame is determined from a combination of a first value divided by a second value that is based on a discontinuous reception (DRX) cycle value of the WTRU and a WTRU identifier modulo the second value;

a receiver configured to monitor transmissions from a network for paging information based on the paging frame; and

wherein the WTRU identifier is related to an international mobile subscriber identity (IMSI) value of the WTRU.

13. The WTRU of claim 12 , wherein the first value is the IMSI of the WTRU.

14. The WTRU of claim 12 , wherein the WTRU identifier is equal to the IMSI.

15. The WTRU of claim 12 , wherein the second value is equal to the DRX cycle value of the WTRU.

16. The WTRU of claim 12 , wherein the WTRU is a long term evolution (LTE) WTRU.

17. The WTRU of claim 12 , wherein the paging frame is referenced to a system frame number.

18. The WTRU of claim 12 further comprising:

the at least one processor is further configured to determine paging occasions based on the determined paging frame.

19. The WTRU of claim 12 , wherein the WTRU is in an idle mode.

20. The WTRU of claim 12 , wherein the WTRU is in DRX in frames other than those related to the paging frame.

21. The WTRU of claim 12 , wherein the DRX cycle value of the WTRU is different than DRX cycle values of other WTRUs.

22. The WTRU of claim 12 , wherein the combination is an addition operation.

23. A network device comprising:

at least one processor configured to determine a paging frame, wherein the paging frame is determined from a combination of a first value divided by a second value that is based on a discontinuous reception (DRX) cycle value of a wireless transmit/receive unit (WTRU) and a WTRU identifier modulo the second value;

a transmitter configured to send, to the WTRU, paging information based on the paging frame; and

wherein the WTRU identifier is related to an international mobile subscriber identity (IMSI) value of the WTRU.

24. The network device of claim 23 , wherein the first value is the IMSI of the WTRU.

25. The network device of claim 23 , wherein the WTRU identifier is equal to the IMSI.

26. The network device of claim 23 , wherein the second value is equal to the DRX cycle value of the WTRU.

27. The network device of claim 23 , wherein the WTRU is a long term evolution (LTE) WTRU.

28. The network device of claim 23 , wherein the paging frame is referenced to a system frame number.

29. The network device of claim 23 further comprising:

the at least one processor is further configured to determine paging occasions based on the determined paging frame.

30. The network device of claim 23 , wherein the WTRU is in an idle mode.

31. The network device of claim 23 , wherein the WTRU is in DRX in frames other than those related to the paging frame.

32. The network device of claim 23 , wherein the DRX cycle value of the WTRU is different than DRX cycle values of other WTRUs.

33. The network device of claim 23 , wherein the combination is an addition operation.
