TL;DR: Load-based radio access network coordination is presented and accompanied by illustrative examples to visualize how the multitude of LTE-Advanced Pro features can be handled in a holistic manner and potential evolution directions of mobile networks are discussed as an initial step toward the standardization of 5G.
Abstract: This article presents an overview of recent 3GPP developments in the area of traffic steering that are shaping the road toward the approaching 5G systems. Due to the increasing availability of RAN features addressing mobile data delivery over a variety of spectrum access techniques, a new traffic steering design is required for the evolving LTE-Advanced Pro standard. LTE evolution toward 5G brings an opportunity to introduce a native and unified approach to the coordination of radio access mechanisms in multi-radio access technology networks for efficient data delivery in mobile networks. This leads to a design of a unified traffic steering framework, aiming at the orchestration of traffic steering related features for optimal radio resource utilization. Load-based radio access network coordination is presented and accompanied by illustrative examples to visualize how the multitude of LTE-Advanced Pro features can be handled in a holistic manner. Based on the proposed solution, potential evolution directions of mobile networks are discussed as an initial step toward the standardization of 5G.

TL;DR: The authors study the LTE-A multi-cell systems' performance using a simulation framework, which integrates several frequency reuse techniques and provides a user-friendly graphical presentation of the evaluation results.
Abstract: Long Term Evolution Advanced (LTE-A) technology is considered as the most possible candidate for next generation mobile communications. LTE-A networks offer high capacity and are specified and designed to accommodate small, high performance, power-efficient end-user devices. Similarly to its predecessor LTE, LTE-A incorporates inter-cell interference mitigation methods in order to mitigate interference and to enhance efficiency in bandwidth usage. These methods include power and frequency allocation schemes that allow neighbouring cells and femtocells in heterogeneous networks to co-ordinately share and reuse available spectral resources, in order to avoid performance degradation for interference suffering cell-edge users. In this paper, the authors study the LTE-A multi-cell systems' performance using a simulation framework, which integrates several frequency reuse techniques and provides a user-friendly graphical presentation of the evaluation results. The optimal Fractional Frequency Reuse (FFR) configuration for the user-defined network instance is also determined, based on overall performance and fairness index metrics. Finally, the authors examine FFR techniques in two-tier femtocell/macrocell environments and evaluate them based on the optimization of different metrics, depending on the network operator's needs.
