Description

IMS Multimedia Telephony service has
been standardized in 3GPP as the replacement of the circuit switched telephony
service in cellular networks. The multimedia telephony service consists of
several service components such as voice, video and text. ‘IMS Multimedia
Telephony over Cellular Systems’ provides a comprehensive overview of the
service that will enable enriched telephony for mobile users. Enriched
telephony fulfils the user’s desire to communicate in new ways, for example by
sharing pictures and video clips.
In addition to an overview of the Multimedia Telephony service, the book
focuses on the modern media processing methods, which allows the quality of
the packet switched voice and video telephony not only to match but also
possibly exceed the quality of circuit switched telephony. Such key components
as adaptive jitter buffering and adaptation of conversational media are
explained in detail.
Key features:

Detailed description of how Multimedia Telephony sessions are set-up and
controlled
Analysis showing the capacity and quality of VoIP and Multimedia
Telephony in cellular networks
Coverage of other IMS services such as PoC specified by 3GPP and OMA
Description of suitable QoS and radio bearers for Multimedia Telephony
Explanation of the modern radio interface, especially High Speed Packet
Access, which is based on concepts such as link adaptation and fast hybrid
ARQ
The possibilities for the current and future standards covered in this book
make it an indispensable resource for engineers, designers and researchers in
VoIP, telecommunication companies and universities teaching and conducting
research in telecommunications. It will also be of interest to managers
needing an in-depth knowledge of the engineering and key issues of this
complex technology, and students aspiring to develop a career in this area.
