Access IP Multimedia Services

The IMS (IP Multimedia Subsystem) is the future
trend that will merge the Internet with the cellular
world. However, a majority of legacy devices today
and future lack coherent support for next generation
networked multimedia services. The goal of this book
is to find a way to access IMS services for non-IMS
devices, especially for the mobile phone devices. In
this book, we proposed a browser-based IMS System
Architecture for the non-IMS devices to access IMS
services. The system architecture mainly focuses on
portable non-IMS devices, but it is also compatible
with fixed devices. Besides, we also proposed
several technical solutions to the problems in
security, provisioning, identity management, inter-
working, and device management. To evaluate the
architecture we implemented three IMS use cases: IMS
Registration, Presence service, and Page mode
Instant Message. Based on the testing result, we
validate the possibility of the system architecture.
The work also outlines a roadmap for future
potential works and system extensions.

In this book, we proposed a browser-based IMS System Architecture for the non-IMS devices to access IMS services. The system architecture mainly focuses on portable non-IMS devices, but it is also compatible with fixed devices.
