Mechanisms for next generation networks services integration across heterogeneous networks

Abstract

After working on research and development, deployment and support of Value-Added Services for Mobile Network Operators for more than a decade, strictly reduced to solutions based on Signaling System N°7 protocol stack, the advent of Next Generation Network standards, paradigms and deployments such as Long Term Evolution and the IP Multimedia Subsystem, adjusting to these new trends became an immediate need, so as not to perish in obsolescence. Albeit Value-Added Services running over legacy Circuit-Switched Core Networks will endure for at least a decade (especially in developing countries), the unavoidable requirement to adapting to whole new paradigms like Service Oriented Architecture and the Internet of Things, tightly coupled with the onset of new technologies and communication protocols like SIP and Diameter based on all-IP Packet Switched Core Networks, set the basis and led us to this research and development work.
