Joint ICIC and Mobility Management Optimization in Self-Organizing Networks

In this work, we propose an optimization framework for joint mobility load balancing (MLB), mobility robustness optimization (MRO) and inter-cell interference coordination (ICIC). The centralized optimization framework achieves balanced network load, avoids MLB related handover problems and considers interference management of the network. Although, this optimization framework forms a theoretical bound for the system capacity, it may also cause an excessive computational complexity to implement. That is why, we also propose a heuristic ICIC compatible conflict avoidance algorithm that provides a distributed solution to the same problem. The results obtained through extensive simulations show that the proposed distributed mobility management algorithm approximates to the optimal solution and offers significant improvements.
