Implementing a Session Aware Policy Based Mechanism for QoS Control in LTE
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 1
Abstract
Quality of Service (QoS) provisioning has become significant with the widely growth of multimedia applications and high increase in the number of users in both wireless and wired networks. In this paper, we implemented a session-aware policy based mechanism for QoS provisioning and control in LTE (Long Term Evolution) networks. Policies are a set of rules identifying the QoS parameters for users. Implementation included DiffServ (Differentiated Services) configuration and setting policies inside the PCRF (Policy Charging Rules Function) which is the brain entity in LTE, then mapping from QCI (QoS Class ID) to DiffServ. Moreover, the dialogue between PCEF (Policy Charging Enforce ment Function) and PCRF was implemented. Simulations on four different traffic application types: VoIP (voice over IP), video, web, and ftp (file transfer protocol) were performed under the network simulator (ns2). Results showed that applying PCEF over th e different traffic applications has a great effect in controlling these applications and specifically UDP (User Datagram Protocol) based applications such as video. Index Terms: QoS, LTE, PCRF, PCEF, EPS.
