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 includes: at the UPF: receiving downlink data of the 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 the QoS indicator received from the SMF, it is determined whether the AMF should serve The RAN of the target UE performs the paging strategy selection; in response to determining that the AMF should perform the paging strategy selection, the QoS indicator is used to identify the QoS information, and the paging strategy selection is performed based at least on the identified QoS information, and based on the selected paging strategy. The paging strategy sends a paging message to the RAN; and in response to determining that the pagi...

Embodiment 2

[0190] Embodiment 2: The method according to embodiment 1, wherein the QoS indicator includes QFI.

Embodiment 3

[0191] Embodiment 3: The method according to embodiment 1, wherein providing the QoS indicator to the AMF includes: sending the QoS indicator in the N11 message.

Abstract

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

Description

[0001] Related application [0002] This application claims the rights and interests of the provisional patent application serial number 62 / 502,122 filed on May 5, 2017, the entire disclosure of which is incorporated herein by reference. Technical field [0003] The present disclosure generally relates to the process of user equipment (UE) paging, and more specifically relates to paging strategy differentiation in the fifth generation (5G) telecommunication system. Background technique [0004] When there is data to be sent to the user equipment (UE) in the network, the network participates in the network to trigger a service request. In order to locate the UE, this may involve a function called "paging", for example, broadcasting a message to one or more last known locations of the UE and listening for responses. Paging can use different methods defined by the "Paging Strategy". The paging strategy can be based on the range of the paging area (how much the page should be broadcas...
