About this
Publication
Written by leading authority, David
Mangini, who has held industry leadership positions including VP of Wireless
Data Solution for AT&T Wireless Services and VP of Wireless Services for
SNET Mobility, this publication addresses both the technical and business
knowledge critical for success in planning for IMS networks and optimized
IMS-based applications and services. It is written in an easy to read style and
is highly informative, with just the right balance of technical information,
business insights, and consultation about the opportunities and potential
pitfalls associated with IMS. Pragmatic in his approach, David instructs of the
merits of IMS to facilitate convergence while maintaining a focus on business
drivers including flexible service creation and delivery, improved cost
structures, and new revenue streams from emerging applications and services
optimized by IMS.
Overview
IP Multimedia Subsystem (IMS) will bring change in telecommunications that
will bring more competition for services, greater mobility, and more specialized
services and content. The drivers behind this change are derived
from large and permanent shifts in the economics of today’s telecom market,
dynamic new technologies that offer more capabilities, and more subtle
shifts in our information age lifestyle that fuels greater demand for value-added
services. IMS will drive convergence in technologies, networks, access,
services, content, revenue, and control at degrees heretofore thought impractical.
This publication will evaluate the
impact of IMS on service creation and delivery with an emphasis on the evolving
needs of users and the resulting impact to wireless platforms and fixed
networks. As a result, business models will change for carriers as well as
content providers due to the enhanced access IMS platforms will provide for
directly reaching end-users across a variety of applications and
networks.
| "IMS is not economically viable if the goal is simply to replicate existing services in a new architecture. The payoff of IMS is to develop and introduce new value-added services for incremental revenue at a lower cost per subscriber.” |
This publication introduces and
discusses critical topics including:
- The importance of
Quality of Service (QoS) and resource allocation optimization in
IMS
- Service Configuration
Management (SCM) as a missing element in the IMS
framework
- Logical staged
introduction of IMS functionality across the Transport, Control, and Services
planes
- Advent and evolution of
the Virtual Network Operator (VNO), positioned to capitalize in
IMS
- Application partnering
for success in IMS services development and deployment
- Predictions for
near-term, intermediate, and long-term introduction of IMS-based
applications
IP Multimedia Subsystem (IMS): Driving New Business Models and Opportunities is a must-have resource for anyone
responsible for planning, designing, implementing, or managing IMS networks
and/or IMS-based applications and services.
