【摘要】：将终端直通技术引入蜂窝网络,可以有效降低终端设备能耗,并提高频谱效率.但蜂窝用户会受到共信道终端直通用户的干扰,导致蜂窝业务接入失败.在嵌入终端直通功能蜂窝网络中,终端直通干扰和频谱资源不足都会导致蜂窝业务的接入失败.针对现有研究缺乏对嵌入终端直通功能蜂窝网络中接入性能分析的问题,提出了新生业务接入失败概率和切换业务接入失败概率来分析终端直通干扰和资源不足对蜂窝业务接入性能的影响.基于随机几何和随机过程,建立了一个随机网络模型来估计嵌入终端直通功能蜂窝网络中新生业务接入失败概率和切换业务接入失败概率.利用上述两个概率可以为网络规划提供帮助,保障蜂窝业务的成功接入.通过仿真,验证了估计的接入失败概率的准确性.
[Abstract]:Introducing terminal through technology into cellular network can effectively reduce the energy consumption of terminal equipment and improve the spectrum efficiency. However, cellular users will be interfered by the common channel terminal direct users, resulting in the failure of cellular service access. Aiming at the problem of lack of performance analysis on access performance of embedded terminal through functional cellular networks, the access failure probability of new service and handover service is proposed to analyze the effect of terminal through interference and resource shortage on access performance of cellular services. A stochastic network model is established to estimate the access failure probability of new services and handoff services in embedded through-functional cellular networks.The above two probabilities can be used to help network planning and ensure the successful access of cellular services.The accuracy of the estimated access failure probability is verified by simulation.
