Building Services on Heterogeneous Networks

摘要

The dream of one single universal mobile telecommunications system turned out to be a dream. Reality is that there are a number of discrete network services. The key challenge for service providers is to turn these heterogeneous network platforms into one homogeneous connectivity service platform. The demonstration of such a platform and the investigation of research issues related to efficiency, cost and a highest possible degree of transparency for the user comprise the first research area of the Next Generation Networks initiative (NGNi). The second research area concerns the study of issues of service discovery and provision over an integrated network platform described previously. Existing service discovery standards were designed use in intranet environments and are thus inappropriate for use in an integrated environment of global scale. Issues to be investigated include overcoming the heterogeneous nature of multi-service networks for the provision of transparent service discovery as well as mechanisms for automatically configuring elaborate request service packages.
