一种基于家庭宽带与MR数据的室内无线测量方法

An indoor wireless network measurement method based on broadband and MR data

室内无线信号的准确测量一直是电信运营商的工作难题,室内信号的准确性是基站小区的规划、无线网优化工作的重要依据。当前网络运营商对于无线网络覆盖质量情况主要通过DT(道路测试)、CQT以及MR(Measurement Report)采集来获得。其中路测数据仅能反映道路覆盖情况,无法采用用户家庭内部覆盖情况;现有MR数据上报的原始数据并无经纬度信息,只能反映整体小区信号覆盖情况,并不能反映精确位置的覆盖信息。而带有经纬度信息的MDT数据又面临着网络开销大、占用硬盘多、空数据比例大和室内定位误差大等缺点,所以如何获得用户在小区居民住宅内覆盖情况对移动运营商解决弱覆盖有着很大的意义。文章提出一种基于移动家庭宽带信息与MR数据关联的方法,利用关键字段实现信息关联从而获得居民室内无线信号的覆盖指标,在测量准确率和测试效率上有了明显提升。

The accurate measurement of indoor wireless network has always been a difficult problem for telecom operators.The accuracy of indoor signals is an important basis for the planning of base stations and the optimization of wireless networks.At present,the wireless network coverage quality of network operators is mainly obtained through DT(road test),CQT or MR(Measurement Report)acquisition.Among them,the road test data can only reflect the signal of road coverage,and cannot use the internal coverage of the user’s home;The original data reported by the existing MR data has no longitude and latitude information,and can only reflect the overall cell signal coverage,but not the coverage information of the precise location.However,the MDT data with longitude and latitude information is faced with the disadvantages of huge networkoverhead,large occupation of hard disk,large proportion of empty data and large indoor positioning error.Therefore,how to obtain the coverage of users in residential areas is of great significance for mobile operators to solve weak coverage.This paper proposes a method based on the association of broadband information and MR data,which uses key fields to achieve information association and obtain the coverage index of indoor wireless signals.The measurement accuracy and efficiency have been significantly improved.
