– This paper discusses the problem of interoperability of IP Telephony and Switched Circuit Networks in the area of routing information. We describe and analyze a solution for directory-based routing. We will present an architecture based on a distributed database on the switched circuit network and the IP network. The aim of the solution is to provide(More)
—A major challenge of future mobile networks is providing the needed elastic scaling to the increased traffic demand, number of users and applications with acceptable cost. Another challenge is suitability for numerous communications applications while curbing unwanted traffic on the air interface and the mobile devices. This paper proposes a vision of how(More)
—The main drivers for the mobile core network evolution is to serve the future challenges and set the way to 5G networks with need for high capacity and low latency. Different technologies such as Network Functions Virtualization (NFV) and Software Defined Networking (SDN) are being considered to address the future needs of 5G networks. However, future(More)
In this paper, we propose the usage of Software Defined Network as mobile backhaul for 5G networks. Mobile networks are facing major challenges to handle the increasing traffic demand. The mobile operators need to improve the effectiveness of their infrastructure. Moreover, they need to enable new business models with their existing network. In this paper(More)
