首先给出了密集市区Vo LT E的覆盖能力，并将其扩展到一般市区、郊区和农村等区域，根据覆盖机制提出了在链路恶化区域实施覆盖增强的举措。其次在分析Vo LT E容量时，先确定了上下行链路的信道开销，进而确认链路可用的R B资源，在此基础上分别计算控制信道和业务信道的LT E语音用户容量，提出最终的核算VoLTE容量的计算方法，有关覆盖和容量的结果可以为今后的VoLTE应用提供有益的参考。%The coverage capacity of VoLTE in dense urban area was presented ifrstly and applied to general urban, suburban and rural areas to propose a solution to coverage enhancement in the area with bad link according to coverage mechanism. Then, in order to analyze VoLTE capacity, the channel overhead of up/down link was determined ifrstly; the available RB resource for link was determined. Based on these, the number of LTE voice users of control channel and service channel were calculated, respectively. Finally, the calculation method of LTE capacity was proposed. The results corresponding coverage and capacity can provide a useful reference to VoLTE applications in the future.
