Abstract
The preset disclosure provides a paging strategy determination method, a device, a RAN network element and a core network element, the paging policy determination method includes: receiving a PPI value sent by a core network element, wherein the PPI value is determined according to the DSCP value of the downlink packet; and determining the paging policy according to the PPI value when the UE in the RRC deactivated state receives the downlink packet.
Claims18
A paging policy determination method applied to a RAN network element, the method comprising:
- receiving a Paging Policy Indication (PPI) value sent by a core network element, wherein the PPI value is determined according to a Differentiated Services Code Point (DSCP) value of the downlink packet;
- determining the paging policy according to the PPI value when the UE in the RRC deactivated state receives the downlink packet;
- wherein prior to receiving the PPI value sent by a core network element, the method further comprises:
- receiving a request message sent by the AMF entity, wherein the request message is used to request the RAN network element to report to the AMF entity, when the UE enters the RRC deactivated state, that the UE enters the RRC deactivated state;
- and
- reporting to the AMF entity that the UE enters the RRC deactivated state when the UE enters the RRC deactivated state, such that the AMF entity reports to the SMF entity that the UE enters the RRC deactivated state.
A paging policy determination method applied to a core network element, comprising:
- sending a Paging Policy Indication (PPI) value to the RAN network element;
- wherein the PPI value is determined according to a Differentiated Services Code Point (DSCP) value of the downlink packet, so that the RAN network element determines the paging policy according to the PPI value when the UE in the RRC deactivated state receives the downlink packet;
- wherein the core network element is an UPF entity, and prior to sending the PPI value to the RAN network element, the method further comprises:
- receiving a PPI value sent by the SMF entity;
- wherein the PPI value is determined by the SMF entity according to the DSCP value of the downlink packet received from the UPF entity;
- wherein sending the PPI value to the RAN network element, comprises:
- adding the PPI value into the N3 tunnel header;
- and
- sending the N3 tunnel header to the RAN network element.
A RAN network element, comprising a transceiver interface, a memory, a processor and a program stored on the memory and capable of running on the processor;
- wherein,
- the transceiver interface is configured to receive a PPI value sent by a core network element, wherein the PPI value is determined according to the DSCP value of the downlink packet;
- the processor is configured to determine the paging policy according to the PPI value when the UE in the RRC deactivated state receives the downlink packet.
