Problems solved by technology

Providing this information should not require the deployment of a dedicated control plane interface (such as the 3GPP Sd interface between the PCRF and the Application Detection Function (ADF: ApplicationDetectionFunction) / Traffic Detection Function (TDF: TrafficDetectionFunction)), because deploying such an interface will cause operational Cost and Network Scaling Issues

Abstract

The invention provides a PCC-framework-based service function chain control method and device. The method comprises PGW receives policy rule information, at least comprising service function chain information, of IP flow from a PCRF, and adds a policy rule information header to an uplink IP packet of IP flow from a user side; a service function execution unit carries out service function on the uplink IP packet according to the policy rule information and transmits the uplink IP packet obtained after execution of the service function to a service function edge function unit; and the service function edge function unit deletes and stores the policy rule information header, wherein the service function edge function unit can serve as an independent entity or be integrated into the PGW. A downlink IP packet corresponding to the IP flow executes the similar scheme. Technical scheme enables a service function chain can be updated dynamically, and provides capability for defining more flexible price plan and more flexible commercial charging mode for service providers.

Description

technical field [0001] The present invention relates to mobile services, in particular to a method and device for controlling a service function chain based on a Policy and Charging Control (PCC: Policy and Charging Control) architecture. Background technique [0002] According to the 3GPP evolved packet core network (EPC: EvolvedPacketCore) protocol (for example, 3GPPTS23.401, 402), user data exchanged by 3GPP users through the mobile access network is encapsulated in a specific channel (tunnel) and terminated in packet data A gateway (PGW: PacketDataNetworkGateWay), the PGW transmits user data to a packet data network (PDN: PacketDataNetwork) through a Gi or SGi interface. However, in actual deployment, user data is not directly exchanged between PGW and PDN. In most cases, user data passes through a set of business functions or value-added services of the so-called "SGi-LAN" between PGW and PDN. The same is true for the user data of the wired network, the user data of th...
