The user-centric mobility support scheme

This paper proposes the mobility scheme based on an user perspective. First, we introduce the concept of the user-centric communication and present the protocol stacks of the User Equipment (UE) for supporting the user-centric mobility in Long Term Evolution (LTE) systems. We design a new protocol stack called Service Continuity Management (SCM). SCM has four functional blocks which is located between the application layer and the transport layer. SCM monitors the service Quality of Experience (QoE) and makes the multiple sessions for a one service using multiple radio adaptors in order to maintain QoE requirements. According to the simulation, the user-centric mobility scheme provides higher QoE score from voice service quality compare to the normal operation.
