Google Tech Talks
January, 14 2008
ABSTRACT
The SIP-based IP Multimedia Subsystem (IMS), while
recently introduced, has become one of the primary
distinguishing features of the next generation of
mobile telecommunication systems. IMS allows
mobile operators to offer advanced value-added
services - like VoIP, so-called push-to-media,
video, interactive gaming, and mobile banking - to
their customers timely and efficiently. Google's
plans to enter the wireless world open up a world
of possibilities for offering customers and
businesses advanced services such as targeted
location-based services and advertisements through
the IMS framework.
Deploying IMS, however, is a non-trivial task. The
core challenge for the telecom industry has been
and will be the integration of the current radio
access network (RAN) and IP transport
infrastructure with the IMS domain. Within
standardization bodies, efforts are underway to
address the issues for call setup and mobility
signaling, while developing unified user profile
management and Quality of Service (QoS)
architectures. The real goal is a standardized,
IMS-centric, end-to-end unified signaling
architecture.
To this end, this presentation provides an
overview of IMS and QoS signaling over integrated
RAN and IMS domains. By using an exemplary family
media service, aspects and specifics of the
end-to-end QoS invocation, control and policy
enforcement, including roaming scenarios, are
demonstrated. Based on laboratory measurements
performed at Sprint-Nextel aided with simulations,
the Post Dial Delay (PDD) delay is evaluated and
some practical recommendations for delay reduction
are presented. The presentation will conclude with
discussion of open issues and viable solutions.
This presentation should be of interest to
Googlers who work on mobile related projects and
intend to have a big picture of next generation
mobile systems such as application development,
and service and system integration with wireless
operators.
This presentation is based on the article S.
Zaghloul, A. Jukan, W. Alanqar: "Extending
QoS from Radio Access to all-IP Core in 3G
Networks - An Operator's Perspective," IEEE
Communications Magazine, Sept 2007.
