Claim 0:
1. 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.
