NGN 201: Core Network: Technology
1. MODULE OVERVIEW
This module will provide an overview of all the technologies, protocols and
standards that are to be used in the core network of a telecommunications
company. This section will cover the underlying technologies and technology
based protocols that will be used in making the Next Generation Network the
cornerstone of a new telecommunication environment.

The Technical aspects of the 3GPP Multimedia System (IMS)
Principles, Standards, Architecture and Applications
A technical overview of the architecture, components and protocols of the
emerging 3GPP IP Multimedia Subsystem (IMS) / 3 GPP2 Multimedia
Domain (MMD) which provides the technological basis for the provision of
mobile multimedia services within converging networks.
The driving forces for the IMS architecture definition, introduces the key
signaling and control protocols of all IP networks (i.e., SIP and Diameter)
forming the basis for IMS component interactions, and explaining the key
IMS elements and their interactions.
The IMS application server options, namely CAMEL, OSA/Parlay and SIP
AS. –
Current IMS products, deployment status and open issues tackled in
