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。

Abstract

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.
