摘要
针对多模终端(multi-mode users equipment,MUE)进行高速业务并行传输时,提高服务质量的同时,带来了大量能耗的问题,提出一种异构网络并行传输能效模型,定义核心内容:最优传输速率分配、网络排位及接入判决规则。依据网络资源情况,对异构网络中所有接入网络进行排位,根据MUE业务传输需求判决哪些网络需要被选择进行并行传输,通过计算得出所有承载网络各自最优分配的传输速率,被选中的承载网络按照最优分配的传输速率对MUE业务进行并行传输,实现能效最大化。通过Matlab仿真分析验证了该改进模型的有效性。
The high speed parallel transmission through multi-mode user equipment(MUE)improves service quality,but also brings a lot of energy consumption.To solve the problem,an energy efficiency model of concurrent transmission in heterogeneous network was put forward.The core contents of the energy efficiency model were defined including optimal transmission rate allocation,as well as the rule of network ranking and access judgment.All the access networks were ranked based on network sources and according to the MUE service transmission requirement,which networks to be selected for parallel transmission were judged.Optimal distributed transmission rate of each carrier network was calculated.The chosen carrier networks parallel transmitted MUE service to achieve maximum energy efficiency according to the optimal distributed transmission rate.The effectiveness of the improved model was verified by the Matlab simulation results.
