    Abstract: Methods and system for supporting traffic steering through a service function chain, the service function chain comprising at least one data processing function. An aspect of the disclosure provides for a method for steering traffic of a packet data unit (PDU) performed by a session management function. The method includes receiving PCC rules from a policy control function, the PCC rules including information comprising at least one of service function chain information; final delivery indication; and selective traffic steering information and associated parameters. The method further includes configuring at least one user plane function (UPF) according to the information. In some embodiments the configuring the at least one UPF includes instructing a first UPF to detect traffic according to the packet detection rules and route the received packet according to the forwarding action rules.

    Abstract: A method includes processing first data from a network node to determine a mobile device is accessing a communication network and to identify a first traffic pattern. The method also includes causing a network device to activate the first network function based on the first traffic pattern. The method further includes processing second data from the network node to determine the communication network is no longer being accessed by the mobile device and to identify a second traffic pattern. The method additionally includes causing the network device to deactivate the first network function and to activate a second network function based on the second traffic pattern. The method also includes determining a first network resource usage and causing a charge rate to be applied for using the first network function based on the first network resource usage.
