摘要 研究了VoLTE的业务模型、容量相关的关键技术以及容量受限因素,对控制信道和业务信道资源调度机制作了细致的研究。根据资源调度机制研究了VoLTE容量性能评估方法,最终在一定配置下应用该方法对控制信道可调度用户数及业务信道可承载用户数进行理论推算,并对理想蜂窝网络结构下的用户容量进行仿真。此外在不同厂家设备条件下,针对VoLTE实验网,对实际业务信道可承载的用户数进行测试。最终确定了实际场景下,VoLTE单小区最大承载用户数可达200个左右,证实了VoLTE可以提供比2G/3G系统更大的承载能力。 The btsiness model, key technologies related with capacity for VoLTE, and limiting factors of capacity were studied, the resource scheduling mechanisms of control channel and traffic channel were meticulously researched, assess method of capacity according to the resource scheduling mechanism was also studied. Under certain configuration, using the method to calculate the number of users that control channel could schedule in theory, the number of users that traffic channel may carry under an ideal cellular network was obtained while simulating the capacity of VoLTE under ideal cellular network. It was eventually confirmed that under actual scenarios, the maximum user number for VoLTE single cell is around 200, proving larger capacity than 2G/3G systems.
