Implementation Of Policy And Charging Control In Packet Core Network

As the popularity of mobile intelligent terminal and the widespread use of mobile applications (such as weibo, renren social website, Kaixin social website and QQ, etc.), data services in the mobile communication network showing explosive growth.The explosive growth of mobile data services on the one hand takes up the vast majority of wireless resources, on the other hand did not give the operators revenue growth.How to use limited mobile network resources to bring more revenue, how to make the mobile network pipeline smarter to become the main issue of the operators. In this paper, we had carried out specific research of the smart packet core pipeline, the identification, control and billing for different user service.First introduced the packet core network and the3GPP PCC architecture; systematically described the node device of Packet core network, the PCRF (Policy and Charging Rule Function Rules of Policy and Charging Control Function) and the PCEF (Policy and Charging Enforcement the Function Policy and Charging enhance the function of the system), and PCC testing purposes and methods. For the specific needs of operators and the difficulties of testing achievement, combined with the existing technical solutions, design and validate a set of hardware and software implementations. A detailed analysis of the operator’s testing requirements for user packet IP address, port number, IP address, QQ, Thunder, etc.A detailed analysis of the operator’s testing requirements for user packet IP address, port number, IP address, QQ, Thunder, etc. Verified the PCEF have the Inspection function for three or four layers of user data parsing, seven analytical and parse application-specific software, add the corresponding billing identifier for the releated data flow, and complete the normal billing functions. Test at the test site environment and the practical application of the live network to meet the operators’ actual demand, to identify the data flow and complete accounting through the inspection of IP address, URL, well-known software applications and other information of UE in the packet core network.
