A new architecture for enhancing the QoS of IPTV video components in LTE systems

IMS (IP Multimedia Subsystem) technologies cannot perform its highest QoS (Quality of Service) approaches as they aren't able to distinguish between the priorities of IPTV (Internet Protocol Television) video components. IMS system also cannot ensure high IPTV data transfer due to the limitation of available cellular bandwidth. In this paper, we try to merge the advantage of high bandwidth assigned to LTE (Long Term Evolution) and a new PHB (Per-Hop Behavior) that classify and differentiate between IPTV sub traffics by using IPv6 Flow Label. This new architecture permits high-quality IPTV video components with the capability to prioritize the sub traffic according to the network administrator policy which itself allows IPTV packets to avoid best-effort treatment. The proposed architecture is implemented using OPNET software using two different scenarios. The obtained results show that IPTV users receive high-quality video data with a change in quantity according to data priority.
