Student thesis: Master's Thesis


With the popularity of mobile devices and advances in wireless network technology a wide variety of Over-The-Top (OTT) applications have been used by mobile user Facing data explosion brought by OTT applications operators act as "bitpipe" and hard to effectively identify different OTT applications from network-level information In this thesis we propose a reference model for application based policy control along with a two-phase packet filtering technique for the 3GPP Policy and Charging Control (PCC) system to perform application awareness for advanced policy control We also present a framework to support application information mapping with PCC functionality and application data flow Moreover an analytical model and extensive simulation are developed to investigate the application detection performed in the PCC system Numerical results showed that packet arrival rate and number of required signature packets significantly affect performance for application detection procedure
