Objective
The IP Multimedia subsystem is an overlay system, that will serve the convergence of mobile, wireless and fixed broadband data networks into a common network architecture where all types of data communications will be hosted in all IP environment using the SIP protocols infrastructure.
As recent public trials have shown, IMS technology still suffers a number of confining factors mainly associated to:
1) Interoperability with underlying communication technologies and legacy infrastructures: IMS should be interoperable not only with the existing circuit switched legacy infrastructures, but also with the various versions of existing packet technologies.
2) Unified resources allocation mechanisms across heterogeneous networks: Guaranteeing a certain type of Quality of Service for a given set of IMS services in end-to-end manner, requires prior invocation of underlying resources negotiation and allocation mechanisms of each network type involved in the context of the call.
3) Terminals IP-level mobility management: Designated to deploy its services over a mixture of network technologies including wireless, mobile and fixed access, IMS should be able of dealing sufficiently with the important issue of terminals mobility management which nowadays is tackled at physical interface level, and results in services robustness weakening and increased probability of disrupted communication.
Building on the results of past and ongoing IST projects related to the research on IMS technology, VITAL aims at consolidating the technological framework that will enable the smooth transition of multimedia communications, including voice, from circuit to packet switched domain of the communications. With respect to this goal, the project will setup an experimental IMS distributed platform, elaborate solutions to the aforementioned problems and test, validate and assess the resultant integrated IMS functionality in the context of advanced traffic experiments and theoretical simulations.
