Paging in a wireless network
A network node comprising a network interface, receiving circuitry, transmitting circuitry, and a processor. The network interface configured to receive a first paging message for a user equipment (UE). The processor is configured to determine a paging occasion for the UE based on a user identity of the UE known to a core network. The processor and the transmitting circuitry configured to transmit to the UE, a control channel having a paging identity and a shared channel. Further, recover an indication of a shared channel resource from the control channel and recover a paging message for the UE from a shared channel signal received using the indication of the shared channel resource.
1. A network node comprising:
a network interface;
receiving circuitry;
transmitting circuitry; and
a processor, wherein:
the network interface is configured to receive a first paging message for a user equipment (UE);
the processor is configured to determine a paging occasion for the UE based on a user identity of the UE known to a core network; and
the processor and the transmitting circuitry are configured to transmit the first paging message to the UE during the paging occasion via a control channel having a paging identity; wherein the control channel has a shared channel resource allocation; and
the processor and the transmitting circuitry are further configured to transmit a shared channel based on the shared channel resource allocation and a radio network temporary identifier (RNTI) assigned to the UE when the UE is in a second state, different than an idle state, and has a radio access network connection.
2. The network node of claim 1 , wherein the shared channel has a second paging message for the UE.
3. The network node of claim 2 , wherein the processor and the receiving circuitry are configured to receive, from the UE, a random access signal in response to the second paging message.
4. The network node of claim 3 , wherein the processor and the transmitting circuitry are configured in response to the received random access signal, to transmit an assignment of a cell-specific radio network temporary identity (C-RNTI).
5. The network node of claim 2 , wherein the second paging message includes a second user identity.
6. The network node of claim 5 , wherein the second user identity is a temporary mobile subscriber identity.
7. The network node of claim 5 , wherein the second user identity is a radio network temporary identity.
8. The network node of claim 1 , wherein the processor and the transmitting circuitry are configured to transmit a control channel having at least one paging indicator bit for the UE, wherein the at least one paging indicator bit indicates whether a paging message is potentially present for the UE.
9. The network node of claim 1 , wherein the shared channel includes a plurality of paging messages for a plurality of UEs.
10. The network node of claim 1 wherein the network node is a base station.
11. A method performed by a network node comprising:
receiving a first paging message for a user equipment (UE);
determining a paging occasion for the UE based on a user identity of the UE known to a core network;
transmitting to the UE, the first paging message during the paging occasion via a control channel having a paging identity; wherein the control channel has a shared channel resource allocation; and
transmitting a shared channel based on the shared channel resource allocation and a radio network temporary identifier (RNTI) assigned to the UE when the UE is in a second state, different than an idle state, and has a radio access network connection.
12. The method of claim 11 , wherein the shared channel has a second paging message for the UE.
13. The method of claim 12 , further comprising in response, from the UE, a random access signal in response to the second paging message.
14. The method of claim 13 , further comprising in response to the received random access signal, to transmit an assignment of a cell-specific radio network temporary identity (C-RNTI).
15. The method of claim 12 , wherein the second paging message includes a second user identity.
16. The method of claim 15 , wherein the second user identity is a temporary mobile subscriber identity.
17. The method of claim 15 , wherein the second user identity is a radio network temporary identity.
18. The method of claim 11 , wherein further comprising to transmit a control channel having at least one paging indicator bit for the UE, the at least one paging indicator bit indicates whether a paging message is potentially present for the UE.
19. The method of claim 11 , wherein the shared channel includes a plurality of paging messages for a plurality of UEs.
20. The method of claim 11 wherein the network node is a base station.
