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.
