【摘要】：將終端直通技術(shù)引入蜂窩網(wǎng)絡(luò),可以有效降低終端設(shè)備能耗,并提高頻譜效率.但蜂窩用戶會(huì)受到共信道終端直通用戶的干擾,導(dǎo)致蜂窩業(yè)務(wù)接入失敗.在嵌入終端直通功能蜂窩網(wǎng)絡(luò)中,終端直通干擾和頻譜資源不足都會(huì)導(dǎo)致蜂窩業(yè)務(wù)的接入失敗.針對(duì)現(xiàn)有研究缺乏對(duì)嵌入終端直通功能蜂窩網(wǎng)絡(luò)中接入性能分析的問題,提出了新生業(yè)務(wù)接入失敗概率和切換業(yè)務(wù)接入失敗概率來分析終端直通干擾和資源不足對(duì)蜂窩業(yè)務(wù)接入性能的影響.基于隨機(jī)幾何和隨機(jī)過程,建立了一個(gè)隨機(jī)網(wǎng)絡(luò)模型來估計(jì)嵌入終端直通功能蜂窩網(wǎng)絡(luò)中新生業(yè)務(wù)接入失敗概率和切換業(yè)務(wù)接入失敗概率.利用上述兩個(gè)概率可以為網(wǎng)絡(luò)規(guī)劃提供幫助,保障蜂窩業(yè)務(wù)的成功接入.通過仿真,驗(yàn)證了估計(jì)的接入失敗概率的準(zhǔn)確性.
[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.
