CQT and Inbuilding System Optimisation Work Process
通信质量拨打测试(CQT)与室内分布系统(IBS)优化工作流程
1.Introduction
简介
This document outlines the CQT and Inbuilding Systems optimisation procedure for the CMCC network in Xi’an.
本文件概述了西安移动通信公司的CQT 与室内分布系统优化工作流程。
The CQT Methodology defined by the CMCC HQ is to benchmark the network performance as perceived by customers inside a building.
由CMCC总部所制定的CQT测试方法主要是用来评估室内用户可感知的网络的性能。
The CQT process/result itself is somewhat subjective and is not a basis for in-depth analysis of the network due to the lack of samples and engineering data.
CQT的测试过程/结果本身由于缺乏客观的工程数据和足够的采样，并非基于对网络性能的全方位的深入分析，所以在某种程度上是比较主观的，有一定的局限性。
To ensure its success, the CQT for a building should be performed after the surrounding or in building cells have been thoroughly optimised.
为保证CQT测试的成功，对某一楼内的CQT测试应该在对其楼内或者其周围小区的全面优化之后进行。
The optimisation procedure outline here is to ensure an acceptable level of network performance inside buildings where there are dedicated IBS providing dominant coverage. 本用户流程是为了保证主要由室内分布系统提供覆盖的建筑物内的网络性能能达到一个可以令人接受的水平。
For buildings where coverage is provided by Macro cells, apply normal optimization procedures.
对于那些已被宏小区覆盖的建筑物内的网络性能，适用常规的优化流程。
2.Candidate Buildings
候选建筑
In con-junction with CMCC, select a certain number of buildings per month for optimization/CQT. The resource scheduling should be balanced that with Drive Test work loads.
移动通信公司每月选定一定数目的建筑物(CQT候选点)供进行的CQT测试和优化，确定需调查的CQT候选点时，应注意其测试和优化工作量要与路测的工作量相平衡、合理搭配。
The list of building should be prioritise according to prominence, traffics and NMO performance.
根据建筑物的重要性、话务量大小与NMO分析的性能等，应对需调查的建筑物(CQT候选点)制订调查的优先级。
3.Optimisation Procedure
优化流程
3.1Data collection
Collect NMO statistics for main serving cells inside the building as specified in Appendix 2.如文件Opt88/CQT/Monthly Report中所详细说明的那样，对于CQT候选点的主服务小区的NMO数据进行收集。
3.2NMO analysis
Investigate cells with
调查小区的下列性能指标
Assignment failure > 4%
RACH >-100dBm
Link Imbalance > 6dB
HO DQ > 30%
HO UQ > 10%
HO failure > 10%
The above indicators are general guidelines only, the performance of the cell as a whole should be considered . Also be mindful that for dedicated IBS, RxLev for both uplink and downlink should be reasonable.
以上指标都只是一般的参考值，小区的总体性能应被考虑在其中。同时还要注意对于建筑物的室内分布系统来说，上行链路与下行链路的接收电平值应当合理。
