Abstract

An apparatus of a next generation NodeB (gNB) comprises one or more baseband processors to receive a downlink Protocol Data Unit (DL PDU) from User Plane Function for a user equipment (UE) in a Radio Resource Control Inactive (RRC_INACTIVE) state, wherein the DL PDU includes a Paging Cause to indicate to the UE a reason for the page, and to send the Paging Cause in a paging message to the UE. The apparatus can include a memory to store the paging message.

First claim

1 . An apparatus of a next generation NodeB (gNB), comprising:
radio frequency circuitry configured to communicate with a user equipment (UE); and one or more baseband processors communicatively coupled to the radio frequency circuitry and configured to perform operations comprising:
receiving a downlink (DL) Protocol Data Unit (PDU) from a User Plane Function (UPF) for the UE in a Radio Resource Control Inactive (RRC_INACTIVE) state, wherein the DL PDU includes a Paging Cause to indicate to the UE a reason for the page; and
sending the Paging Cause in a paging message to the UE.

2 . The apparatus of claim 1 , wherein the Paging Cause indicates a type of traffic that has caused the paging.

3 . The apparatus of claim 2 , wherein the type of traffic includes Internet Protocol (IP) Multimedia Subsystem (IMS) voice traffic, IMS Short Message Service (SMS) traffic, IMS other traffic, or non-IMS traffic.

4 . The apparatus of claim 1 , wherein the Paging Cause is determined by a Core Network of the UPF.

5 . The apparatus of claim 1 , wherein Paging Cause is sent to the UE in a downlink (DL) Protocol Data Unit (PDU) SESSION INFORMATION header.

6 . A function of a core network (CN) configured to perform operations, comprising:
processing a Differentiated Service Code Point (DSCP) value received from a User Plane Function (UPF); and determining a Paging Cause for a user equipment (UE) in a Radio Resource Control Inactive (RRC INACTIVE) state based on the DSCP, wherein the Paging Cause indicates a reason for the page.

7 . The function of claim 6 , wherein the core network includes a Session Management Function (SMF), and the SMF is to determine the paging cause.

8 . The function of claim 6 , wherein the Paging cause indicates a type of traffic that has caused the paging.

9 . The function of claim 8 , wherein the type of traffic includes Internet Protocol (IP) Multimedia Subsystem (IMS) voice traffic, IMS Short Message Service (SMS) traffic, IMS other traffic, or non-IMS traffic.

10 . One or more machine readable media having instructions thereon that, when executed by an apparatus of a next generation NodeB (gNB), result in:
receiving a downlink (DL) Protocol Data Unit (PDU) from a User Plane Function (UPF) for a user equipment (UE) in a Radio Resource Control Inactive (RRC INACTIVE) state, wherein the DL PDU includes a Paging Cause to indicate to the UE a reason for the page; and sending the Paging Cause in a paging message to the UE.

11 . The one or more machine readable media of claim 10 , wherein the Paging cause indicates a type of traffic that has caused the paging.

12 . The one or more machine readable media of claim 10 , wherein the type of traffic includes Internet Protocol (IP) Multimedia Subsystem (IMS) voice traffic, IMS Short Message Service (SMS) traffic, IMS other traffic, or non-IMS traffic.

13 . The one or more machine readable media of claim 10 , wherein the Paging Cause is determined by a Core Network of the UPF.

14 . The one or more machine readable media of claim 10 , wherein Paging Cause is sent to the UE in a downlink (DL) Protocol Data Unit (PDU) SESSION INFORMATION header.

15 - 18 . (canceled)

19 . An apparatus of a user equipment (UE), comprising:
radio frequency circuitry configured to communicate with a a next generation NodeB (gNB); and one or more baseband processors communicatively coupled to the radio frequency circuitry and configured to perform operations comprising:
receiving a paging message from the gNB when the UE is in a Radio Resource Control Inactive (RRC_INACTIVE) state, wherein the paging message includes a Paging Cause to indicate to the UE a reason for the page.

20 . The apparatus of claim 19 , further comprising a dual subscriber identification module (SIM).
