"IP-Oriented
QoS in the Next Generation Networks: Application to Wireless Networks"
Emerging Internet Quality
of Service (QoS) mechanisms are expected to enable wide spread use of
real time services such as VoIP and videoconferencing. The "best effort"
Internet delivery cannot be used for the new multimedia applications.
New technologies and new standards are necessary to offer Quality of
Service (QoS) for these multimedia applications. Therefore new communication
architectures integrate mechanisms allowing guaranteed QoS services
as well as high rate communications.
The service level agreement
with a mobile Internet user is hard to satisfy, since there may not
be enough resources available in some parts of the network the mobile
user is moving into. The emerging Internet QoS architectures, differentiated
services and integrated services, do not consider user mobility. QoS
mechanisms enforce a differentiated sharing of bandwidth among services
and users. Thus, there must be mechanisms available to identify traffic
flows with different QoS parameters, and to make it possible to charge
the users based on requested quality. The integration of fixed and mobile
wireless access into IP networks presents a cost effective and efficient
way to provide seamless end-to-end connectivity and ubiquitous access
in a market where the demand for mobile Internet services has grown
rapidly and predicted to generate billions of dollars in revenue.
This tutorial covers to the
issues of QoS provisioning in heterogeneous networks and Internet access
over future wireless networks as well as ATM, MPLS, DiffServ, IntServ
frameworks. It discusses the characteristics of the Internet, mobility
and QoS provisioning in wireless and mobile IP networks. This tutorial
also covers routing, security, baseline architecture of the inter-networking
protocols and end to end traffic management issues.

"The 3GPP IMS as Service Platform for Next Generation Wireless
Multimedia Applications - Practical Experiences from the OPEN IMS Playground@FOKUS"
This tutorial starts with
a review of the IMS architecture as a multimedia applications enabler
clarifying the relationship between IMS core and application layer.
The tutorial reviews the key interfaces in between IMS core and application
layer and studies the main IMS applications server options (namely CAMEL,
OSA and SIP AS). The tutorial will focus particularly on new emerging
SIP Application Servers based on Servlet technologies. The tutorial
ends with an overview of the FOKUS IMS play ground (www.fokus.fraunhofer.de/ims)
and practical service examples.

division at the Fraunhofer Institute FOKUS, which also provides the
national NGN platforms and applications test and development centre
in Germany (www.fokus.fraunhofer.de/ngni). This testbed, covering also
the famous Open IMS playground forms the basis for many R&D and
industry projects performed for many international vendors and network
operators. Prof. Magedanz is senior member of the IEEE, editorial board
member of several journals, and the author of more than 200 technical
papers/articles. He is the author of two books on IN standards and IN
evolution. Based on his 17 years of experience in the teaching complex
IT and telecommunication technologies to different customer segments
in an easy to digest way, he is a globally recognised technology coach.

"Future
Open Mobile Services"
This tutorial provides an
overview of research on future mobile service architecture focusing
on adaptive service creation, deployment, provision and management in
heterogeneous mobile environments. Services include not only traditional
communication ones such as telephony, conferencing, etc. but also multimedia
ones such as email, videophone, word processing, web surfing, etc. The
user may use a variety of services offered by different operators and
also third parties on multiple heterogeneous terminals. The services
are also delivered through heterogeneous networks with different capabilities.
It is more appropriate to separate the service into two parts, core
service and service adaptation. The service adaptation should be carried
out dynamically at run time and by the service execution environment.
In order to perform service adaptation, the service execution environment
must have information about the service QoS requirements, information
about the characteristics of the communication link and information
about terminal capabilities. It is necessary to have tools to gather
and manipulate that dynamic information, especially when the user is
roaming between heterogeneous multi-provider networks. It is also crucial
to meet the user·s demand of service diversity, service personalisation
and context awareness. The tutorial will also provide an overview of
current approaches to mobile services such as VHE, MExE, J2ME, J2EE,
WAP, IMS, SIP, etc.

"WiFi
and WiMax: Theory and Practice"
The first half of the tutorial
addresses the family of standards that fall under the WiFi forum. It
starts by describing the DSSS and OFDM signaling schemes of 802.11b,
g and a. It then describes the MAC layer for the same family in
its original form which was intended for short range indoor WLAN. The
tutorial then addresses recent MAC enhancements and provisioning for
outdoor access including: mesh networking, rural communications, long
distance point-to-point, fast hand-off and integration with the 2G/3G
infrastructure.
The second half addresses
the group of standards that fall under the WiMax forum which are based
on 802.16. We describe the physical layer for various 802.16 systems
including 802.16e. Single Carrier, OFDM and OFDMA transmission
strategies are discussed with TDD, FDD and MESH framing. The structure
of the WiMax MAC layer is described including the data mapping and packet
scheduling of OFDMA frames. The expanding range of applications
for both 802.11 and 802.16 families is discussed by giving several deployment
scenarios.
