Abstract

We present a new approach for mobility load balancing (MLB) and user association in dense small cell scenarios. This Self Organizing Network (SON) approach relies on Knapsack Optimisation (KO) to evenly distribute users across participating cells subject to constraints. It is shown that the new technique referred to as (MLB-KO) achieves substantial improvements (better than three times reduction) in blocking ratios for the studied use cases.
