• Heterogeneous wireless networking
• Vertical handover
• Radio resource management
• Handover time

One major requirement that has to be satisfied in heterogeneous wireless networking environments is the support for real time services and applications that are becoming increasingly popular and should be effectively supported end-to-end. Thus special emphasis should be given for the design and dimensioning of the handover procedure which becomes a challenge when a user is moving within heterogeneous systems. In this work we deal with the problem of handover time minimization for bandwidth demanding and real time services in 4th generation wireless communications systems. In particular we present a framework for handover execution as well as its associated procedures that are activated adaptively to the available resources for achieving bounded latency, together with their performance which is evaluated via simulations.
