批量操作方法

amosbatch ipdatabase ‘lt all;st cell’ipdatabase 为批量EnodeB站名列表

amos -m rnc11,10.1.128.17

amos -m rbslist.txt 'lt all; kget'

参数查询指令:get . specialSubframePattern

参数配置指令:set . specialSubframePattern XX

(XX为对应要修改的值)

其他说明:修改参数需要闭解小区。

上下行时隙对比在网络中应保持一致,以避免小区间干扰。

参数配置指令:set EUtranCellTDD=BHHCGuangDongLuKou-ELH-1 rachRootSequence 630

(以将扇区BHHCGuangDongLuKou-ELH-1的参数设置为630为例)

其他说明:如果功能“Automated RACH Root Sequence Allocation”未开启,则直接修改即可生效。如果功能“Automated RACH Root Sequence Allocation”开启,则需要闭解小区才能生效。

1.3 推荐配置

以下为参数的推荐配置配置

这套参数的含义是每个对应qci的承载式10,每个qci承载的负载了为10/4000。

小区的负载率为所有qci承载值之和。

当两个负载均衡小区负载率的差值大于lbThreshold=30/1000时,启动负载均衡流程。

单个负载均衡周期内最大可调整的负载率差值为200/1000。

2 异频负载均衡的统计

下面的分别是统计负载均衡的统计点

?pmLbMeasuredUe

–Records the number of UEs selected for measurements

qualifying for load balancing action towards cells on the

related frequency. Those values are accumulated each

ROP. Used to calculate the LB measurement success

rate for the related cells.

–MOC: EUtranFreqRelation

?pmLbQualifiedUe

–Records the number of UEs qualified for load balancing

action towards the related cell. Those values are

accumulated each ROP. Used to calculate the LB

measurement success rate for the related cell.

–MOC: EUtranCellRelation

?pmHoPrepAttLteInterFLb

–The number of attempts to start outgoing intra LTE inter

frequency handover preparation due to load balancing.

–Sub-counter to pmHoPrepAttLteInterF (legacy)

–MOC: EUtranCellRelation

?pmHoPrepSuccLteInterFLb

–The number of successful outgoing intra LTE inter

frequency handover preparations that was performed for

load balancing reasons.

–Sub-counter to pmHoPrepSuccLteInterF (legacy)

?pmHoExeAttLteInterFLb

–The number of outgoing intra LTE inter frequency

handover execution attempts due to load balancing.

–Sub-counter to pmHoExeAttLteInterF (legacy)

frequency handovers that was performed for load

balancing reasons.
