Paging in a wireless network

1. A network device comprising:

circuitry configured to receive, from a core network, a paging message related to a user equipment (UE);

a processor configured to send, on a control channel in a long-term evolution (LTE) network in response to reception of the paging message, a signal to indicate a page of the UE and the signal includes an indication of a shared channel for the UE to receive;

wherein the signal is derived from a radio network temporary-identifier (RNTI); and

the processor further configured to send a transmission to the UE on the indicated shared channel.

2. The network device of claim 1 , wherein the paging message includes one of an international mobile subscriber identity (IMSI) or temporary mobile subscriber identity (TMSI).

3. The network device of claim 1 , wherein the control channel is one of a shared control channel (SCCH) or a broadcast channel.

4. The network device of claim 1 , wherein the shared channel is a contention-based channel.

5. The network device of claim 1 , wherein the RNTI is cell-specific.

6. The network device of claim 1 , wherein the RNTI is used for a plurality of cells.

7. The network device of claim 1 , wherein the control channel is a channel for carrying uplink and downlink resource allocations.

8. The network device of claim 1 , wherein the signal is sent in a time interval derived from an international mobile subscriber identity (IMSI) associated with the UE.

9. A user equipment (UE) comprising:

a processor configured to monitor, in a long-term evolution (LTE) network, downlink transmissions for a signal to indicate a page from a network device, wherein the signal includes an indication of a shared channel and the signal is derived from a radio network temporary identifier (RNTI);

and

circuitry configured to receive a transmission on the indicated shared channel.

10. The UE of claim 9 , wherein the processor configured to monitor is further configured to utilize discontinuous reception and monitors the downlink transmissions in time intervals derived from an international mobile subscriber identity (IMSI) associated with the UE.

11. The UE of claim 9 , wherein the monitored downlink transmissions are a set of control channels indicated by the LTE network.

12. The UE of claim 9 , wherein the indication of the page includes one of an international mobile subscriber identity (IMSI) or temporary mobile subscriber identity (TMSI).

13. The UE of claim 9 , wherein the RNTI is used for a plurality of cells.

14. The UE of claim 9 , wherein the monitored downlink transmissions include channels for carrying uplink and downlink resource allocations.

15. The UE of claim 9 , wherein the shared channel is a contention-based channel.

16. The UE of claim 9 , wherein the RNTI is cell-specific.

17. The UE of claim 9 , wherein the signal is received, by the UE, in a time interval derived from an international mobile subscriber identity (IMSI) associated with the UE.

18. A method performed by a network device, the method comprising:

receiving, by the network device from a core network, a paging message related to a user equipment (UE);

sending, on a control channel in a long-term evolution (LTE) network by the network device in response to receiving the paging message, a signal to indicate a page of the UE and the signal includes an indication of a shared channel for the UE to receive;

wherein the signal is derived from a radio network temporary identifier (RNTI); and

sending a transmission to the UE on the indicated shared channel.

19. The method of claim 18 , wherein the paging message includes one of an international mobile subscriber identity (IMSI) or temporary mobile subscriber identity (TMSI).

20. The method of claim 18 , wherein the control channel is one of a shared control channel (SCCH) or a broadcast channel.

21. The method of claim 18 , wherein the shared channel is a contention-based channel.

22. The method of claim 18 , wherein the RNTI is cell-specific.

23. The method of claim 18 , wherein the RNTI is used for a plurality of cells.

24. The method of claim 18 , wherein the control channel is a channel for carrying uplink and downlink resource allocations.

25. The method of claim 18 , wherein the signal is sent in a time interval derived from an international mobile subscriber identity (IMSI) associated with the UE.

26. A method performed by a user equipment (UE), the method comprising:

monitoring, by the UE in a long-term evolution (LTE) network, downlink transmissions for a signal to indicate a page from a network device, wherein the signal includes an indication of a shared channel and the signal is derived from a radio network temporary identifier (RNTI); and

receiving, by the UE, a transmission on the indicated shared channel.

27. The method of claim 26 , wherein the monitoring utilizes discontinuous reception and the UE monitors the downlink transmissions in time intervals derived from an international mobile subscriber identity (IMSI) associated with the UE.

28. The method of claim 26 , wherein the monitored downlink transmissions are a set of control channels indicated by the LTE network.

29. The method of claim 26 , wherein the indication of the page includes one of an international mobile subscriber identity (IMSI) or temporary mobile subscriber identity (TMSI).

30. The method of claim 26 , wherein the RNTI is used for a plurality of cells.

31. The method of claim 26 , wherein the monitored downlink transmissions include channels for carrying uplink and downlink resource allocations.

32. The method of claim 26 , wherein the shared channel is a contention-based channel.

33. The method of claim 26 , wherein the RNTI is cell-specific.

34. The method of claim 26 , wherein the signal is received, by the UE, in a time interval derived from an international mobile subscriber identity (IMSI) associated with the UE.
