Paging in a wireless network
A user equipment (UE) is configured to determine paging occasions based on a discontinuous reception (DRX) and a UE identification. Further, the UE is configured to monitor control channel signals in the paging occasions for an identifier associated with paging which is based on one of the control channel signals having the identifier associated with paging and to recover an indication of a shared channel resource from the one control channel. The UE is further configured to recover a paging message for the UE from a shared channel signal received using the indication of the shared channel resource.
1. A user equipment (UE) comprising:
a transceiver; and
a processor, operatively coupled to the transceiver, wherein
the transceiver and the processor are configured to:
determine paging occasions based on a discontinuous reception (DRX) and a UE identification,
monitor control channel signals in the paging occasions for an identifier associated with paging,
based on one of the control channel signals having the identifier associated with paging, recover an indication of a shared channel resource from the one control channel signal, and
recover a paging message for the UE from a shared channel signal received using the indication of the shared channel resource.
2. The UE of claim 1 wherein a group of UEs receive the one of the control channel signals and the identifier associated with the paging is a radio network temporary identifier (RNTI) associated with the group.
3. The UE of claim 2 wherein the UE has an assigned cell RNTI (c-RNTI) and the c-RNTI is different than the identifier associated with the paging.
4. The UE of claim 1 wherein based on the paging message, the transceiver and the processor are configured to initiate a random access procedure to obtain a connection for a network oriented call.
5. The UE of claim 4 wherein based on the initiated random access procedure, the transceiver and the processor are configured to receive a radio bearer setup message.
6. The UE of claim 1 wherein the paging message indicates a system information update and the transceiver and the processor are configured to acquire and update the system information based on the paging message.
7. The UE of claim 1 wherein the UE ID is an IMSI.
8. The UE of claim 1 wherein the UE ID is a TMSI.
9. The UE of claim 1 wherein the transceiver and the processor monitor a subset of the control channel signals in the paging occasions based on preprogramed information in the UE.
10. The UE of claim 1 wherein the shared channel signal includes a plurality of paging messages for a plurality of UEs.
11. A method for use by a user equipment (UE), the method comprising:
determining paging occasions based on a discontinuous reception (DRX) and a UE identification,
monitoring control channel signals in the paging occasions for an identifier associated with paging,
based on one of the control channel signals having the identifier associated with paging, recovering an indication of a shared channel resource from the one control channel signal, and
recovering a paging message for the UE from a shared channel signal received using the indication of the shared channel resource.
12. The method of claim 11 wherein a group of UEs receive the one of the control channel signals and the identifier associated with the paging is a radio network temporary identifier (RNTI) associated with the group.
13. The method of claim 12 wherein the UE has an assigned cell RNTI (c-RNTI) and the c-RNTI is different than the identifier associated with the paging.
14. The method of claim 11 wherein based on the paging message, initiating a random access procedure to obtain a connection for a network oriented call.
15. The method of claim 14 wherein based on the initiated random access procedure, receiving a radio bearer setup message.
16. The method of claim 11 wherein the paging message indicates a system information update and acquiring and updating the system information based on the paging message.
17. The method of claim 11 wherein the UE ID is an IMSI.
18. The method of claim 11 wherein the UE ID is a TMSI.
19. The method of claim 11 wherein the UE monitors a subset of the control channel signals in the paging occasions based on preprogramed information in the UE.
20. The method of claim 11 wherein the shared channel signal includes a plurality of paging messages for a plurality of UEs.
