摘　　要：分析了LTE网络的技术能力，包括小区吞吐量，PDCCH、PHICH和PUCCH信道容量，接入容量，寻呼容量等，并基于技术能力分析了各种典型业务的PRB、PDCCHCCE、PUCCH、PRACH、寻呼、RRC连接等网络资源的消耗和占用情况，最后推导了限制LTE网络提供更多用户服务的瓶颈资源，提出了建设和运营优化时重点考察的瓶颈指标建议。The technical capability of LTE network was analyzed, which included cell throughput, channel capacity of PDCCH, PHICH and PUCCH, random access capacity, paging capacity and so on. Then, based on the technical ability, the consumption and occupancy of network resources such as PRB, PDCCH CCE, PUCCH, PRACH, paging, RRC connection were analyzed. Finally, the bottleneck resources which restrict the LTE network to provide more customer service were deduced, and the bottleneck index proposal which focuses on the construction and operation optimization was put forward.
