Intelligent Selection of Access Nodes for Multi-Interface Mobile Terminals
This paper tackles the problems of intelligent interface selection for mobile terminals connected to Fixed & Mobile Converged (FMC) network and equipped with multiple network interfaces of different access technologies. Selection mechanisms that can be found in today's networks are analyzed and their drawbacks are estimated. A new selection policy retaining the VoIP quality above a pre-defined threshold is elaborated. The new policy eliminates the drawbacks of today's algorithms, its easy realisation and integration in networks is possible thanks to the Integrated Mobility and Resource Management Mechanism. The performance of different selection policies is compared using ns2.
