1. A method performed by a Policy Control Function (PCF) node for enabling user plane traffic classification in a communications system supporting Control and User Plane Separation (CUPS) with multiple User Plane Function (UPF) nodes, the method comprising:
receiving, from a Session Management Function (SMF) node, a policy request for a User Equipment, UE;
obtaining, from a Unified Data Repository (UDR) an indicator indicating Classification Optimization for Multiple User plane functions (COMU) for the UE; and
transmitting, to the SMF node, a policy response comprising the indicator indicating COMU.
