The further integration of networks and improvement of transmission capabilities will enable the exchange of information to take place anytime, anywhere. It will also have an impact on major aspects of our lives, including business and education.

Compared to the traditional television system, IPTV integrates TV, IP, telecoms and digital media business model to bring about a wide range of innovations that not only affect service and technology but also the whole industry.

Fixed-mobile convergence is one of the most important trends in the telecom industry. IMS is a well-recognized sub-system under the NGN architecture, and a core technology of FMC.

Although FMC is undoubtedly a leading component that is helping to set the trend for the telecom business of the future, the industry still faces a long stretch before FMC becomes a realization, along with its converged services, terminals and networks. Backing up this idea is the fact that FMC service convergence is still in its infancy stage, while progress on convergence of the FMC terminal and network is just beginning to be seen.

Currently, the development trend in communication networks seems to definitely be going toward the convergence of fixed and mobile networks. The course of development from an existing, to a fully converged network, can be divided into three basic phases, which are: 1st phase, the creation of a service layer convergence based on the existing network; 2nd phase, the establishment of the Pre-IMS; and the 3rd phase, the development of a fully converged IMS. It should also be noted that network characteristics and developing strategies in different phases will be different as well.
