Iptv In China's Development Strategy-iptv, Ngn, 3g-communication Industry - Sodium

0 Introduction NGN, 3G and 3G evolution, WiMAX

, IPTV and NGBW, fixed-mobile convergence (FMC) and so is the communication industry and explore the hot topic of concern, it hopes to NGN, NGBW and FMC to solve the many types of network problems, such as network security, QoS issues, intelligent network management, network mobility and include the "triple play" network, including aggregation and fusion, smooth evolution of backward compatibility, set up to increase ARPU and net profit margin (APPU) and the effective multi-service value-added and profitable business models. and IPTV is large have been associated with NGN . For a profound understanding of the essence and the development of IPTV to the controversy, must have sufficient understanding of NGN and understanding.

1NGN the definition and connotation 1. 1NGN definition NGN following the October 10, 1996 the Clinton administration put forward a clear plan of action for the next generation Internet (NGI) and the ITU and ETSI, IETF-matching crystal. NGN concept put forward, it is IP popular in the successful expansion of the many exposed, while the apparent lack of convergence as IP technology on the expectations, and ". COM" bubble and subsequent global telecommunications downturn and the modern digital transmission, signal processing and advanced software engineering technology, the integrated product of modern science and technology, marking the expected specific implementation steps by the NGN gradually to GII this ideal goal, also marked the evolution of forward and backward compatible with smooth, easy and more value-added and profitable business next-generation network era is coming.

ITU-T Study Group 13 in the February 2004 meeting, after heated debate, gives the basic definition of NGN:

A) NGN is a packet-based network switching technology, including telecommunications services it can provide various services, including, to use a variety of broadband and the ability to have guaranteed quality of service delivery technology.

B) This should enable a variety of functions and services related to implementation and use of various transmission-related technology independent.

C) NGN enables users free access to different service providers.

D) NGN and support the universal mobility, which can provide users with a consistent and ubiquitous services.

1. 2NGN meaning A broad perspective, it should be said, NGN is a target network, it is not the next generation of the Internet, nor is the next generation of PSTN telephone network, next generation telecommunications networks, cable television or broadcast the next generation network, but gradually by the new generation of packet-switched transmission, and IP protocol-based financial voice, video, data in one face of the new network.

It will really make the network facilities from time, space and bandwidth limitations, the full realization of the network of personal and individual, so that network-based virtual world and the real world, the perfect integration of the network with the so-called near-zero at that end to end QoS network with excellent performance, satisfaction and system reliability and network availability, and thoroughly reliable network security.

Up to the global intelligent network management,
