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.
