US 11,910,295 B2 · Apparatus and method for controlling network slice data rate in wireless communication system

Abstract

The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data rate after a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments, a method for operating a network node in a wireless communication system is provided. The method comprises obtaining slice policy information including a maximum data rate, monitoring a data rate of protocol data unit (PDU) sessions associated with the slice, determining whether a sum of data rates of PDU sessions associated with the slice exceeds the maximum data rate, transmitting, to a second network node, a policy enforcement request message for controlling the sum of data rates of the PDU sessions associated with the slice.

Dependent claims

A method for operating a policy control function (PCF) in a wireless communication system, the method comprising:

obtaining network slice related policy information including a maximum data rate for a network slice of a single-network slice selection assistance information (S-NSSAI), wherein the maximum data rate includes a maximum bit rate (MBR) of guaranteed bitrate (GBR) Quality of Service (QOS) flows and an aggregate maximum bit rate (AMBR) of non-guaranteed bitrate (non-GBR) QoS flows;
monitoring a data rate associated with the network slice;
determining whether the data rate associated with the network slice exceeds the maximum data rate;
reducing the AMBR of the non-GBR QoS flows not to exceed the maximum data rate in case that it is determined that the data rate associated with the network slice exceeds the maximum data rate, to control the data rate associated with the network slice;
and
transmitting, to a session management function (SMF), a policy update request message including the reduced AMBR.
