摘　　要：网络验收是网络交维前运营商把控网络质量与用户感知的第一关,是保证网络正常运行的重要一环。中国联通网研院对5G NSA无线网室外单站、室内覆盖系统及网络的验收方法及指标展开研究,通过理论分析、现网实测等方式制定无线覆盖类指标、速率类指标、PING时延类指标及接入/移动/保持类指标,全面合理地把控工程验收环节,并从网络优化的角度,对5G网络验收过程中未达到规划、验收门限要求的基站网络提出优化思路,保证验收工作的顺利进行。Before the new-constructed network are transferred to maintainer,network acceptance is the first key to control the network quality and user perception of operators and manufacturers.The acceptance methods and indicators of outdoor single station,indoor coverage system and network of 5G NSA wireless network are studied,and the wireless coverage index,rate index,PING delay index,accessing/mobile/maintaining index are drafted by theoretically analyzing and actual measurement of existing network,which could control project acceptance link comprehensively and reasonably.And then,from the point of view of network optimization,it puts forward optimization ideas for base stations or networks that fail to meet the requirements of planning and acceptance threshold in the process of 5G network acceptance to ensure the implementation of acceptance work.
