Integrated Broad-Band Communication Systems in Belgium

Belgian politicians, the National Telecommunications Administration (RTT), and the telecommunication industry in general fully realize the major economic, industrial, and social importance of an advanced telecommunications infrastructure for the future of the country. A national effort is therefore underway. This paper describes the specific Belgian telecommunications environment, its development towards an ISDN infrastructure, and evolution towards the integration of telecommunication and distribution services into a uniform broad-band communication network. The present network structures for both telecommunication and distribution services are briefly discussed in this paper. Furthermore, plans and experiments in the area of ISDN are also described. Explanations related to the basic concepts of a national integrated broad-band communication network and possible architectures for a demonstration project are given.     

Introducing Widget-based IMS Client Applications

Classic telecommunication methods and Internet services are converging. For this reason Telecommunication companies are looking for new ways to include their services in Web 2.0 applications. A strong candidate for the telecommunication infrastructure of the future is the IP Multimedia Subsystem (IMS), an all IP telecommunication core network. In the last few years a new kind of application has increasingly gained popularity: they are known as widgets. Widgets are small but fancy applications based on Web technologies that are very easy to develop. This paper describes a new approach to combining widgets with telecommunication features, such as Voice over IP calls or messaging, using IMS. Our solution includes a new abstraction layer with interfaces for the different telecommunication capabilities. Moreover, we implemented a widget engine that makes these telecommunication interfaces available to its widgets. Our solution allows the rapid development of new IMS client applications and a short time-to-market. The combination of other Web 2.0 services with IMS features becomes an exploitable opportunity.

Mobility support in wireless Internet

The tremendous advancement and popularity of wireless access technologies necessitates the convergence of multimedia (audio, video, and text) services on a unified global (seamless) network infrastructure. Circuit-switched proprietary telecommunication networks are evolving toward more cost-effective and uniform packet-switched networks such as those based on IP. However, one of the key challenges for the deployment of such wireless Internet infrastructure is to efficiently manage user mobility. To provide seamless services to mobile users, several protocols have been proposed over the years targeting different layers in the network protocol stack. In this article we present a cross-layer perspective on the mobility protocols by identifying the key features of their design principles and performance issues. An analysis of the signaling overhead and handoff delay for some representative protocols in each layer is also presented. Our conclusion is that although the application layer protocol is worse than the protocols operating in the lower layers, in terms of handoff delay and signaling overhead, it is better suited as a potential mobility solution for the next-generation heterogeneous networks, if we consider such factors as protocol stack modification, infrastructure change, and inherent operational complexity.
