摘　　要：为了降低基于中继技术的B3G/4G网络建设成本,通过分析网络建设成本与基站、中继节点数量比之间的关系,提出了成本效率模型。由成本效率模型推导出等成本直线,并将之与等容量曲线结合,进一步提出了成本优化模型。该模型明确地为B3G/4G蜂窝网络建设方案的评估与优化提供了直接有效的分析模型。仿真结果表明,在同样的系统容量和覆盖范围需求下,该模型可以有效分析网络建设成本,确定成本最优点。In order to reduce the construction cost of relay-based B3G/4G cellular network, by analyzing the relationship between the network construction cost and the ratio of base stations and relay nodes, this paper conducted a cost-efficiency model, from which an iso-cost line was derived. Combination of iso-cost line and the capacity curve led to a cost optimization model. For the first time, this model explicitly provides an effective model for cost assessment and optimization of B3G/4G cellular network construction. The simulation results demonstrate that the cost optimization model can effectively decrease network construction cost based on the same system capacity and coverage requirements.
