本申请涉及大数据技术领域,尤其涉及一种基于MDT的室内信号外泄分析方法及***。This application relates to the field of big data technology, and in particular to a method and system for analyzing indoor signal leakage based on MDT.
背景技术Background technique
目前,移动网络中的4G网络覆盖已经比较完善,尤其是城市内部室外覆盖的信号质量比较好,但在靠近建筑物的街道道路上经常遇到掉话、通话质量不好的问题,严重影响用户感知,这种情况大部分是由于室内信号外泄造成的。正常情况下,室内信号应主要覆盖室内区域,室外覆盖由宏小区承担,在建筑物***要控制室内信号的强度,从而避免室内信号外泄到室外,从而保证室外终端优先接入室外宏小区,减少由于室内信号快速衰减造成的掉话、通话质量差等问题,因此及时发现全网室内信号外泄问题是网络优化的一个重要内容。At present, the 4G network coverage in the mobile network has been relatively complete, especially the signal quality of the outdoor coverage inside the city is relatively good, but on the streets and roads close to the buildings, the problems of dropped calls and poor call quality are often encountered, which seriously affects users Perception, this situation is mostly caused by indoor signal leakage. Under normal circumstances, indoor signals should mainly cover indoor areas, and outdoor coverage is undertaken by macro cells. The strength of indoor signals must be controlled at the periphery of the building to prevent indoor signals from leaking to the outdoors, thereby ensuring that outdoor terminals preferentially access outdoor macro cells. To reduce the problems of dropped calls and poor call quality caused by the rapid attenuation of indoor signals, it is an important content of network optimization to find out the problem of indoor signal leakage of the entire network in time.
而现有技术主要有路测或投诉触发的人工方式,存在如下缺陷:However, the prior art mainly has manual methods triggered by drive tests or complaints, which have the following defects:
1)路测触发方式一般是在室内分布建设初期,进行统一的测试,之后按需进行,一旦后续周边情况发生变化,无法及时发现,并且路测核查区域有限,无法频繁进行全网排查;1) The drive test trigger method is generally to conduct a unified test in the initial stage of indoor distribution construction, and then conduct it on demand. Once the surrounding situation changes later, it cannot be found in time, and the drive test verification area is limited, so it is impossible to conduct frequent network-wide investigations;
2)投诉触发方式是根据投诉位置进行定点分析,如果该位置被多次投诉,而且问题现象类似,同时在建筑物的***边缘区域,则有可能是室内信号外泄的原因,则需要现场对这片区域的室内室外信号进行测量,最终确定是否室内小区信号泄漏到***区域。这种方式的局限性在于只能用于问题发生后的处理,无法进行事前的全网排查。2) The complaint trigger method is to conduct a fixed-point analysis based on the complaint location. If the location has been complained many times and the problem is similar, and at the same time in the peripheral edge area of the building, it may be the cause of the indoor signal leakage. The indoor and outdoor signals in this area are measured to determine whether the indoor cell signal leaks to the peripheral area. The limitation of this method is that it can only be used to deal with the problem after it occurs, and it cannot conduct pre-existing network-wide investigations.
