Providing IPTV in the IMS network

Abstract

Providing IPTV in the IMS network is increasingly a problem solved today. All households are gradually passing through innovation and slowly every equipment becomes the so-called intelligent or smart and can be connected to a private or public network where it can be monitored, configured, diagnosed and then repaired.. This same upgrading takes place in television, and its current output is in the form of IPTV (Internet Protocol Television) provided in the IP Multimedia Subsystem Network, a new generation network that provides both audio and video data. IMS has originated in 1999 for the 3GPP standard in the 5th edition when switching from a 2G network to a 3G network. It has supported the older GSM and GPRS networks, but also a new UMTS network. In the sixth edition, it also has began to work on WLAN networks, more voice-oriented, or speech recognition services. This paper focuses on the provision of IPTV (Internet Protocol Television) in the IMS (IP Multimedia Subsystem) network. The aim of our paper is to design IPTV services in the IMS network, define the IMS architecture and the IMS network components such as HSS (Home Subscriber Server), various types of CSCF (Call State Control Function), describe the functionality and services provided by IMS and IPTV and, finally, compare the quality of the IPTV service provided by our network and by network of selected operator.
