IPTV Quality of Service Improvement Approach Over LTE Network

Abstract

The latest experiences hint that 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. Success of IPTV services depends on how the customer perceives QoS related to the provided stream. The satisfaction of this factor is crucial to the success of IMS services. This need constitutes a major challenge for the IMS-based IPTV on the horizon of overcoming the failure of existing QoS models namely IntServ (Integrated Services) and DiffServ (Differentiated Services). 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.
