1. A method of implementing an application rule for an application to be accessed by a User Equipment (UE) in a user session in a Service Based Architecture (SBA) domain in a 3GPP 5G core network of a telecommunications system, said SBA at least comprising a Policy Control Function (PCF), an Application Function (AF), a User Plane Function (UPF), and a Session Management Function (SMF), said method comprising the steps of:
receiving, by said PCF, an application rule comprising (i) an AF identifier (AF-ID) identifying said application rule, (ii) an application identifier (App-ID) identifying said application, and (iii) at least one service requirement for servicing said application in said SBA domain, wherein said application rule is different from existing Policy Charging and Control (PCC) rules and has higher precedence than existing per session PCC rules, and
instructing, by said PCF, said SMF to execute said at least one service requirement to all present and future user sessions pertaining to said application.
