EFFECTIVE PREDEFINED POLICY AND CHARGING CONTROL PCC INSTRUCTION HANDLING MECHANISM FOR COMMUNICATION SYSTEMS

摘要

Examples of the invention relates to an effective PCC instruction handling mechanism for communication systems such as 3GPP NR. A first control plane device (e.g. a SMF) configures and instructs a user plane device (e.g. a UPF) to install Policy and Charging Control (PCC) instructions that are relevant for at least one client device (e.g. a UE) by transmitting a control message to the user plane device. The control message transmitted to the user plane device comprises a first information element instructing the user plane device to install a received PCC instruction as a predefined PCC instruction and a second information element instructing the user plane device to activate the received PCC instruction. The first control plane device receives the PCC instruction in a control message from a second control plane device (e.g. a CPF). Thereby, e.g. reduced complexity in the first control plane device is possible and bulky signalling messages over communication interfaces is avoided in the communication system.
