Application driven SON

Recently, the self organization approach has been incorporated into the 3rd Generation Partnership Project (3GPP) standards in order to implement mechanisms such as auto configuration, auto healing, and self optimization of the deployed network architecture. However, the Self Organization Networks (SONs) functionalities in Long Term Evolution (LTE) do not include Heterogeneous Networks (HetNets) scenarios that involve trusted non-3GPP access points (e.g., trusted Wi-Fi networks). Moreover, fulfill Quality of Experience (QoE) for users on a perapplication base, it is not the goal of SON. In this paper, we will focus on the requirements for the next-generation SON, which should aim at assisting the Mobile Network Operator (MNO) in order to maintain the QoE by using per-flow optimization, taking into account the latest proposals about data offloading and the simultaneous use of multiple interfaces.
