| 摘 要： | 针对LTE网络中小区之间负载不均衡的问题,提出了一种结合经济学中的博弈理论的解决方案.通过将博弈理论中的拍卖模型引入到LTE系统模型中,建立竞拍双方的效用函数,求出均衡解最大化其效用函数,从而合理地调整切换参数将热点小区的负载转移到目标小区.仿真结果证明了该算法的有效性,该方案可以合理有效地解决小区间负载不均衡问题、优化网络资源和提高资源利用率.

| Abstract: | A solution based on the game theory is presented in order to solving the cell load unbalance problem in the LTE networks. Through introducing an auction game theoretical model into the LTE system model, establishes the utility function. And then maximizes the utility function through seeking the solution of Nash equilibrium, thus transfers the load of the overload cell to the target cell consequently by adjusting handover parameters. The simulation results indicate the effectiveness of the algorithm, which can achieve the balance of load, optimize the network resources allocation and improve the resource utilization. |
