Fixed mobile convergence: challenges and solutions

Fixed mobile convergence is an emerging technology, which aims at integration and creation of a unified communication infrastructure from fixed and wireless mobile networks. In this converged communication infrastructure, users move across networks and access services seamlessly using different devices. Voice and video over IP is one of the emerging technologies in the realization of FMC. In this article we first discuss the features and technological requirements of FMC networks. We then present an architecture for implementing FMC and describe how to realize the voice call continuity of VoIP sessions using the current IP infrastructure. We further identify the requirements for VVoIP in ensuring video call continuity as well as the challenges associated with the migration from voice to multimedia services.
