Problems solved by technology

Unlike EPS where MME can access QoS information, certain entities within the 5G system that can perform paging policy differentiation (such as SMF and AMF) cannot access QoS information

Embodiment 1

[0189] Embodiment 1: A method for distinguishing paging strategies in a 5G telecommunication network, the method comprising: at the UPF: receiving downlink data of a target UE; and in response to receiving the downlink data, providing a data notification to the SMF, The data notification includes a QoS indicator; at the SMF: in response to receiving the data notification from the UPF, the QoS indicator is provided to the AMF; at the AMF: in response to receiving the QoS indicator from the SMF, it is determined whether the AMF or the service should be The RAN of the target UE performs paging policy selection; in response to determining that the paging policy selection should be performed by the AMF, using a QoS indicator to identify QoS information, performing paging policy selection based at least on the identified QoS information, and The paging strategy sends a paging message to the RAN; and in response to determining that the paging strategy selection should be performed by ...

Abstract

According to one aspect of the present disclosure, a paging policy differentiation method in a 5G telecommunication network is provided. The User Plane Function (UPF) receives the downlink data of the target User Equipment (UE) and provides the Session Management Function (SMF) with a data notification including a Quality of Service (QoS) indicator, which the SMF uses to determine QoS Information (QoSI) sent to the Access Management Function (AMF). The AMF determines whether the paging policy selection should be performed by the AMF or the Radio Access Node (RAN) serving the target UE; if performed by the AMF, the AMF selects the paging policy based on the QoSI and sends the paging message to the RAN, and the RAN responds to the The UE performs paging; if performed by the RAN, the AMF provides the paging policy information to the RAN, which selects the paging policy and pages the UE accordingly.

Description

[0001] Related applications [0002] This application claims the benefit of Provisional Patent Application Serial No. 62 / 502,122, filed May 5, 2017, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates generally to user equipment (UE) paging procedures, and more particularly to paging policy differentiation in fifth generation (5G) telecommunication systems. Background technique [0004] When there is data in the network to be sent to a user equipment (UE), the network participates in a network-triggered service request. To locate the UE, this may involve a function called "paging", eg, broadcasting a message to one or more of the UE's last known locations and listening for responses. Paging can take different methods defined by "paging policies". The paging strategy can be based on the range of the paging area (how far the page should be broadcast), the paging response time (how long the network should...
