IMS: The Technology, Applications, and Challenges

Course ID

P-IMS1

Duration

3 day(s)

Aimed At

Professionals and managers responsible for telecommunications planning, design, engineering, deployment, business strategy, marketing, and services creation. You should have a couple of years of telecommunications experience including work with one or more wireless technologies such as GSM, CDMA/CDMA2000, UMTS, and WiMAX.

Course in a Nutshell

Communications networks are rapidly evolving into policy-based, packet-oriented networks intended to provide a particular quality-of-services (QoS) to subscribers while reducing the costs of capital expansions, network operations, and management. If you are in telecommunications engineering, deployment, strategy, marketing, or services creation, it is imperative that you understand the technology and business implications of IMS.

In this course, you will look at IMS from all angles including the technology, status of wireless and wireline standards, key challenges posed by the technology, financial drivers for its adoption, deployment, and even security considerations. You will also study the issue of network policy and how the different levels and types of policies for QoS and admission control have important implications for traffic engineering in the evolving networks. We will conclude with a look at the future of telecommunications networks, including a flat, all-IP infrastructure.
