Control and Management

Abstract: The ETSI Technical Committee (TC)
GRID is addressing issues associated with the convergence of IT and
Telecommunications, with particular reference to the lack of interoperable Grid
solutions. The integration of grid technology provides new revenue streams for
Telecom operators through their converged fixed, mobile and data services from
their Next Generation Network (NGN) and by offering “Grid and cloud
computing data” services reusing the current deployed NGN infrastructure.
TC GRID identified the gaps and overlaps that need to be addressed for this
interconnection. This paper analyses two interconnection scenarios for
combining grid and NGN applications in a unified architecture. The proposal
takes advantage of standardized interfaces and current technology features for
integrating NGN and Cloud Services. The use of the TISPAN Resource and
Admission Control System (RACS) and Policy and Enforcement Manager (PEEM) are
described as possible vehicles for the integration.
Title: Method for Characterization and Classification
of Localization/Tracking Systems
Authors: Sarel
De Wet (
Abstract: Due to the large
variety of different tracking and localization systems, intended for different
applications from different disciplines, researchers and developers are faced
with a problem when comparing these systems as they are not presented in a
general form. This paper discuss and expands on the important aspects of two of
the most helpful papers in the field in order to present a method for
characterizing and classifying systems into a general form, enabling easier
comparison of systems as well as making better design choices.

Abstract: The IP Multimedia Subsystem has largely been standardized. Of critical
importance is the development of services which exploit the rich functionality
and deployment environment provided by the IMS. However, the age-old challenge
of mobility management still persists at the IMS layer. While substantial
research has been done focusing on this issue, the approaches taken have
largely been at lower layers of the protocol stack. Recent higher-layer
solutions, on the other hand, have not directly focused on the specific
challenges and opportunities presented by IMS multimedia session continuity.
Further, the expressive and feature-rich information from presence service, and
the interactivity of the RTSP protocol have largely been ignored. This paper
presents a proof of concept scenario-based analysis of how presence information
and the RTSP protocol can be leveraged to provide an enhanced multimedia
session continuity experience. It presents an introduction of the session
continuity service, overviews related work and outlines the framework for an
enhanced session continuity experience.
