Paging optimization
Methods and systems for providing paging optimization are described. In one embodiment, a method for processing a paging request in a wireless network system includes sending, by a User Equipment, a Physical Random Access Channel (PRACH) preamble; receiving, by the UE, a paging request; receiving, by the UE, a Random Access Response; sending, by the UE, a response with the response having a cause labeled as a paging response in place of an Radio Area Network (RAN)-based Notification Area (RNA) update response; receiving, by the UE, an RRCResume message; sending, by the UE, an RRCResume Complete message; and sending, by the UE, a paging response.
1. A method for processing a paging request in a wireless network system, comprising:
receiving, from a User Equipment (UE), a Physical Random Access Channel (PRACH) preamble;
sending, to the UE, a paging request;
sending, to the UE, a Random Access Response;
receiving, from the UE, a response with the response having a cause labeled as a paging response in place of an Radio Area Network (RAN)-based Notification Area (RNA) update response;
sending, to the UE, an RRCResume message;
receiving, from the UE, an RRCResume Complete message; and
receiving, from the UE, a paging response, further comprising when the RRCResume request is received from the UE before transmission of the paging request, storing a paging message and processing the paging message after completion of an Radio Area Network (RAN)-based Notification Area (RNA) update.
2. The method of claim 1 wherein the response comprises a RRCResumeRequest.
3. The method of claim 1 further comprising restarting all timers related to the RNA update after sending the response.
4. The method of claim 1 wherein an RNA update is not received.
5. The method of claim 1 wherein the UE is communicating with a gNB.
6. The method of claim 1 , further comprising:
receiving, from the UE, a response with the response having a cause labeled as a paging response in place of a Radio Area Network (RAN)-based Notification Area (RNA) update response.
7. The method of claim 6 wherein the response comprises a RRCResumeRequest.
8. The method of claim 6 wherein the UE is communicating with a gNB.
9. The method of claim 8 further comprising storing the paging message by the gNB in place of forwarding the paging message to the UE if an RRC timer is about to expire.
10. The method of claim 9 further comprising sending a paging failure message after the RNA update is complete.
11. The method of claim 6 further comprising when a timer for a periodic RNA update is about to expire, storing by a gNB a paging message and processing the paging message after completion of the periodic RNA update.
12. The method of claim 6 further comprising when the RRCResume request is received before transmission of the paging request, storing by the gNB the paging message and processing the paging message after completion of the RNA update.
13. A system for providing paging optimization, comprising:
a User Equipment (UE);
a gNB in communication with the UE; and
a core network in communication with the gNB; wherein
when an RRCResume request is received by the gNB from the UE before transmission of a paging request, the gNB stores a paging message and processes the paging message after completion of an Radio Area Network (RAN)-based Notification Area (RNA) update.
