Abstract

A method of operating a UPF in a wireless communication system includes receiving a data packet, identifying a PFCP session context associated with the data packet, determining whether a PDR associated with the PFCP session context should be modified or a new PDR should be created, transmitting a request to a session management function to provision a new or modified PDR at the UPF, receiving a session modification response from the SMF provisioning the new or modified PDR for the PFCP session context at the UPF, and applying the new or modified PDR on the data packet.
