摘要
TDD-LTE与LTE-FDD混合组网对网络规划依赖较高。为实现LTE混合组网的基站选址自规划,使网络同时满足覆盖、能效比、负载、成本最优,提出了一种均衡多目标优化的混合组网基站选址规划模型。结合LTE混合组网理想回传的特点,重新构建多个目标优化函数,利用改进的离散多目标粒子群算法,从Pareto解集中模糊折衷选取较优解进行优化。仿真结果表明,提出的网络自规划方法能够综合提高网络性能同时减少成本,具有较好的应用价值。
The hybrid network of TDD-LTE and LTE-FDD has a high dependence on network planning.In order to realize the self-planning of the base station selection of the LTE hybrid network and make the network meet the requirements of coverage,load,energy efficiency and cost optimization,a hybrid networking base station location selection self-planning model with balancing multi-objective optimization is proposed.Based on the characteristics of LTE hybrid networking ideal backhaul,this model reconstructs multi-objective optimization functions.The improved discrete multi-objective particle swarm optimization algorithm is used to optimize the model by selecting better solutions from the Pareto solution.The case simulation results show that the proposed network self-planning method can improve network performance and reduce cost,and has good application value.
