Abstract

The tighter and tighter converging integration of fixed and mobile telecommunication networks along with the telecom-IP network convergence have opened up the enormous market potential for a rich ecosystem of Next-Generation (NG) converged net-work technologies and services. Such NG services are envisioned to have the capability of seamlessly exploiting all the population of Web applications already available in the IP network and at the same time of leveraging the legacy capabilities and functions of typically proprietary and less open telecom-munication networks. To some extent, the evolution trend is similar to what is happening for pervasive and ubiquitous services in all IP-based mobile computing. Since device miniaturization and wireless communications are making more and more feasible mobility-enhanced services to exploit all potential and opportunities of mobile computing, the goal of the mobility scenarios is becoming the realization of easily and automatically integrated services, towards the ultimate objective of disappearing computing, i.e., the seamless and transparent collaboration of wireless devices to most human activities without the need of explicit user/administration intervention. However, this vision of both converged and seamlessly integrated NG wireless services introduces novel challenging issues for the software infrastructure necessary to support that scenario. The chal-lenges stem from the fact that a converged network needs to carry a multitude of high-bandwidth services over heterogeneous networks that are distributed, multipoint, diverse, and interactive in nature. Support infrastructures will not just relate to the creative routing of connections based on database lookups, but will take on a broader scope including multimedia session management, co-ordination of multi-protocol connections, horizontal/vertical handoff management, mobility predictions, advanced security, … In addi-tion, to stay ahead in the competition and provide market leading offerings, NG network providers further need to enable a global ecosystem of third-party independent application developers to deliver NG converged services by leveraging open standard-based service delivery platforms. Moreover, to establish a common architecture, standards and frameworks will be required to ensure the interoperability of converged networks and services, also to facilitate best utilization of the existing telecommunication infrastructures within the converged ecosystem. Therefore, not to increase too much the burden of NG service designers and implementers in the articulated and converged wireless deployment sce-nario of the future, there is the need for novel middleware solutions capable of addressing connectivity-level, integration, and context-dependent support aspects.
