Abstract
Ensuring Accounting accuracy is paramount in any mobile network. With the advent of Control and User Plane Separation (CUPS) in Third Generation Partnership Project (3GPP) specifications, beginning in 4G network implementations and extending to 5G network implementations, the erstwhile monolithic gateway has been split into two independent nodes, a control plane network function referred to as the Session Management (SMF) and a user plane network function referred to as the User Plane Function (UPF). This separation renders the UPF unaware of some of the events that have occurred at the SMF, which can result in billing inaccuracies. Proposed herein are techniques that may provide subscriber usage accounting accuracy and may also facilitate optimizing signaling between the SMF and the UPF.
