QoS Aware Multi-homing in Integrated 3 GPP and non-3 GPP Future Networks

In future networks, collaboration of heterogeneous wireless access technologies is inevitable. 3GPP has already standardized the interconnection of non-3GPP access technologies with the exiting 3GPP access networks. This enables users to make seamless vertical handovers between available access networks. However, the question still remains whether the non3GPP access technologies can deliver the Quality of Service (QoS) demands of user applications? Within the context of the Open Connectivity Services (OConS) of the SAIL European project, this work investigates the effects of the integration of two network types on user Quality of Experience (QoE). In order to accomplish QoS guaranteed service from non-3GPP access technologies, this paper proposes a novel resource management algorithm. With the help of simulation results it is proved that network operators can get significant performance boost for their networks when the proposed scheme is deployed in an environment with heterogeneous access networks.
