Self-organized neighborhood mobility load balancing for LTE networks

摘要: This paper investigates mobility load balancing (MLB) in a hexagonal LTE (Long Term Evolution) macro cellular deployment. Gain and cost of MLB is evaluated by downlink (DL) system simulations terms quality service (QoS) enhancement versus increased resource expenses. A novel distributed SON (self-organizing network) algorithm, termed as neighborhood (NMLB) presented which also includes non-adjacent cells the optimization area compared to classical approach only adjacent neighbor are considered area. The simulation results show that NMLB gives significant gain w.r.t. traffic throughput complex scenarios where capacity not available but further away cells.
