QoS Based IPTV over LTE-WLAN Heterogeneous Networks

Abstract

Heterogeneous networks required IP Multimedia Subsystem (IMS) technologies to perform their control signaling and improve their communication services. However, the highest IPTV-QoS cannot be performed using IMS only as it cannot differentiate between IPTV video components. In this paper, we implement our IPTV-flow label technique in LTE-WLAN heterogeneous systems that used to improve QoS by providing IPTV sub traffic priority according to the network administrator policy. The proposed architecture has been implemented and analyzed using Opnet Modeler 17.5 software. The produced results demonstrate that IPTV users receive high definition video data with a variation in quantity in conformity with data priority by using Opnet 17.5 software.
