Description

一种射频头端定位方法及射频头端定位系统
本申请要求于2017年9月30日提交中国专利局、申请号为201710923623.X、申请名称为“一种射频头端定位方法及射频头端定位系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种射频头端定位方法及射频头端定位系统。
背景技术
随着室内数字化的不断加强，伴随着室内容量的增长需求，运营商不断加强对室内的深度覆盖，越来越多的射频头端(Pico Remote Radio Unit，PRRU)被应用于室内。业主从安装美观考虑，要求PRRU安装在天花板吊顶内，安装完成之后，在日常维护阶段，当PRRU出现故障时，维护人员无法准确找到这些PRRU。施工人员在按照设计图纸安装PRRU的时候，由于技能和工程交付界面的问题，往往不会精确标记实际安装位置。因为PRRU的数量非常多，这样，即便有设计图纸，也不知道实际的具体位置安装了哪个PRRU，导致后续要对这些PRRU维护的时候，维护人员无法找到这些PRRU。
现有的方法是通过无线部署工具(Wireless Deployment Tool，WDT)在现场施工时对PRRU扫描电子序列号(Electronic Serial Number，ESN)并绑定位置。具体为：WDT导入工程设计图纸，在施工时，工程队或者督导按照PRRU的实际安装位置，扫描安装PRRU的ESN，并在WDT上做手工绑定，在所有PRRU安装完毕后，将绑定的PRRU的位置信息导入到U2000网管系统使用。
但是，现场施工时对PRRU扫ESN并绑定位置存在以下的问题：不同的局点一般是由不同的施工队负责，相同的局点也可能同时存在多个施工方；每个局点都需要专门的培训，合同界面推动难，多个工程队同时施工，依赖工程队采集有合同界面问题，需要增加成本；施工队技能低，采集容易引入误差，无法审计；WDT有终端要求，施工队的现有终端参差不齐，需要增加成本，如果都由督导执行，督导本身存在瓶颈，一个督导对应多个工程队，需要扫描时，工程队可能已经安装完毕，导致无法扫描。因此，导致PRRU的位置依然难以准确得到，影响了后期的室内系统运维的高效进行。
发明内容

所述网管服务器获取所述路测事件的网管侧路测信息，所述网管侧路测信息包括所述路测事件对应的射频头端；
所述网管服务器根据所述网管侧测量信息得到射频头端标识；
所述网管服务器根据所述网管侧测量信息和所述终端侧路测信息，得到与所述射频头端标识绑定的射频头端位置信息。
当用户使用路测终端进行路测时，由于路测过程是用户在走动时，进行不同位置的定点测量，那么路测事件是一次次的，而且每一次路测事件进行时，路测终端都是临时接入到一个射频头端中，在测试期间或者测试完成之后，路测终端获取到该次路测事件的终端侧路测信息，路测事件不仅仅包括一次，也可以是多次。由于每一次路测事件进行时，路测终端临时接入到一个射频头端中，而网管服务器与射频头端是连接的，那么网管服务器也可以获取到路测事件对应的网管侧路测信息，而且路测事件对应的射频头端也记录在网管侧路测信息中。网管服务器在得到的网管侧测量信息中，包括路测事件对应的射频头端，在已知射频头端的情况下，网管服务器可以通过网络获取或者预先设置了与射频头端相对应的射频头端标识。由于路测终端在每次路测事件接入到一个射频头端，路测终端可以自动记录路测事件所归属射频头端的位置在终端侧路测信息，或者记录路测终端本身在室内的位置在终端侧路测信息，根据都是一个路测事件的网管侧测量信息和终端侧路测信息，就能够计算得到射频头端位置信息，将射频头端标识与射频头端位置信息进行绑定，就实现了射频头端定位。相比于现场施工时对射频头端扫射频头端标识并绑定射频头端位置信息的方案，无需施工队现场扫描，可以在后期通过路测终端的路测过程完成，在工程标准化动作中顺带采集信息，完成位置的自动绑定，使得射频头端定位方便；并且室内射频头端数量多，有的安装在天花板内，无法快速找到故障射频头端的安装位置，根据终端侧路测信息和网管侧路测信息自动关联绑定射频头端位置信息和射频头端标识，保障了系统运维的高效率。

具体实施方式
本申请提供了一种射频头端定位方法及射频头端定位系统，通过路测时记录终端侧路测信息和网管侧路测信息，并根据终端侧路测信息和网管侧路测信息自动关联绑定射频头端位置信息和射频头端标识，使得射频头端定位方便，保障了系统运维的高效率。
下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
首先简单介绍本申请应用的系统构架或场景。
如图1所示，为本申请的系统构架或场景的示意图，其中路测终端是具有通信功能的电子设备，具体可以是手机等，在路测过程中，路测终端可以通过室内的多个PRRU中的一个与网管服务器连接。用户在使用路测终端进行路测时，是可以进行移动的，而且是进行不同位置的定点测量，每一次测量称作为一次路测事件。
根据以上的描述，请参阅图2所示，本申请实施例提供一种射频头端定位方法，包括： 201、路测终端获取路测事件的终端侧路测信息；
本实施例中，当用户使用路测终端进行路测时，由于路测过程是用户在走动时，进行不同位置的定点测量，那么路测事件是一次次的，而且每一次路测事件进行时，路测终端都是临时接入到一个射频头端(PRRU)中，在测试期间或者测试完成之后，路测终端获取到该次路测事件的终端侧路测信息，路测事件不仅仅包括一次，也可以是多次。
202、网管服务器获取路测事件的网管侧路测信息；
本实施例中，由于每一次路测事件进行时，路测终端临时接入到一个PRRU中，而网管服务器与PRRU是连接的，那么网管服务器也可以获取到路测事件对应的网管侧路测信息，而且路测事件对应的PRRU也记录在网管侧路测信息中。
203、网管服务器根据网管侧测量信息得到射频头端标识；
本实施例中，网管服务器在得到的网管侧测量信息中，包括路测事件对应的PRRU，在已知PRRU的情况下，网管服务器可以通过网络获取或者预先设置了与PRRU相对应的射频头端标识，射频头端标识具体可以是设备序列号(Equipment Serial Number，ESN)，ESN作为PRRU的唯一标识。
204、网管服务器根据网管侧测量信息和终端侧路测信息，得到与射频头端标识绑定的射频头端位置信息。
本实施例中，由于路测终端在每次路测事件接入到一个PRRU，那么在已知PRRU施工时候的，PRRU布局的情况下，路测终端可以自动记录路测事件所归属PRRU的位置在终端侧路测信息，或者记录路测终端本身在室内的位置在终端侧路测信息，根据都是一个路测事件的网管侧测量信息和终端侧路测信息，就能够计算得到PRRU位置信息，将ESN与PRRU位置信息进行绑定，就实现了PRRU定位，对于已经定位的PRRU自然不需要重新进行定位了。
本申请实施例中，相比于现场施工时对PRRU扫ESN并绑定位置的方案，无需施工队现场扫描，可以在后期通过路测终端的路测过程完成，在工程标准化动作中顺带采集信息，完成位置的自动绑定，使得PRRU定位方便；并且室内PRRU数量多，有的安装在天花板内，无法快速找到故障PRRU的安装位置，根据终端侧路测信息和网管侧路测信息自动关联绑定PRRU位置信息和PRRU标识，保障了系统运维的高效率。
上述实施例中，PRRU位置信息可以是根据在施工时的PRRU设计图已经确定，也可以是不知道PRRU位置信息的情况，此时具体PRRU定位可以通过下面的两种方式来实现，下面通过实施例分别进行详细说明。
(一)、请参阅图3，本申请实施例提供一种射频头端定位方法，包括：
301、路测终端通过射频头端设计图获取射频头端布局信息；
本实施例中，在施工阶段，PRRU的安装位置已经设计好了，那么PRRU设计图上就有PRRU布局信息。
302、路测终端获取路测事件的测量事件标识及射频头端；
本实施例中，在路测终端进行路测过程时，每一次路测事件都临时接入到一个PRRU中，那么就能得到该次测量事件标识以及PRRU，测量事件标识包括临时移动用户标识 (Temporary Mobile Subscriber Identity，TMSI)和时间戳，路测终端每一次接入到PRRU都只是单次呼叫，因此每次的接入都会产生一个独有的TMSI，时间戳指的是路测终端每次进行路测事件的时间，TMSI和时间戳可以唯一的指示该路测终端的一此路测事件。
303、路测终端根据射频头端及射频头端布局信息，确定射频头端位置信息；
本实施例中，路测终端在每次路测事件时都能知道接入的PRRU，而已知PRRU布局信息的情况，可以确定每次路测事件时的PRRU的PRRU位置信息。
304、路测终端根据射频头端位置信息及测量事件标识得到终端侧测量信息；
本实施例中，路测终端将得到的PRRU位置信息及包含TMSI和时间戳的测量事件标识合并成为终端侧测量信息。
305、网管服务器获取路测事件的网管侧路测信息；
本实施例中，由于每一次路测事件进行时，路测终端临时接入到一个PRRU中，而网管服务器与PRRU是连接的，那么网管服务器也可以获取到路测事件对应的网管侧路测信息，路测事件对应的PRRU记录在网管侧路测信息中，而且路测事件的TMSI和时间戳也记录在网管侧路测信息中。
306、网管服务器解析网管侧测量信息，得到路测事件对应的射频头端；
本实施例中，网管服务器解析网管侧测量信息，就能得到路测事件得到每次路测事件对应的PRRU。
307、网管服务器根据预置射频头端配置和存量信息，得到射频头端的射频头端标识；
本实施例中，网管服务器根据预先设置的PRRU配置和存量信息，可以知道每个PRRU所对应的ESN，进行匹配，就可以得到PRRU的ESN。
308、网管服务器根据测量事件标识，将网管侧测量信息和终端侧路测信息进行关联；
本实施例中，由于每一次路测事件时，网管侧测量信息和终端侧路测信息都会记录TMSI和时间戳，那么根据TMSI和时间戳就能将网管侧测量信息和终端侧路测信息进行关联。
309、网管服务器解析终端侧路测信息得到射频头端位置信息；
本实施例中，已知了终端侧路测信息中包含了PRRU位置信息，网管服务器解析终端侧路测信息得到PRRU位置信息。
310、网管服务器根据预置绑定算法，将射频头端标识与射频头端位置信息进行绑定。
本实施例中，网管服务器采取预置绑定算法，将射频头端标识与射频头端位置信息进行绑定，预置绑定算法需要根据不同情况，采用不同的算法，具体可以包括以下三种：(1)、PRRU位置相邻关系绑定算法；(2)、迭代绑定算法；(3)、路测相邻关系绑定算法。分别进行说明：
(1)、由于路测事件没有时间的先后顺序出现PRRU的关系，路测事件个数不足的情况下，某些PRRU位置信息的确定由于路测事件个数不足，达不到设定门限而与ESN绑定失败，这是就可以使用PRRU位置相邻关系绑定算法，如图4所示，未绑定的ESN可以依次迭代，根据信号大小的关系，在已经绑定的ESN集合中找到相邻的ESN(图4中0_129_1与0_132_1相邻，0_130_1与0_131_1相邻)，根据路测事件的位置，已经绑定的PRRU位置，绑定未绑定的PRRU位置；
(2)、由于PRRU信号波动较大，容易受到跨楼层影响(楼上楼下共小区)，导致PRRU位置的周围的路测事件点与实际的ESN不一致，如图6所示，PRRU1就受到了0_134_1、0_136_1、0_90_1(跨楼层ESN)的干扰；PRRU3受到了0_136_1的干扰。因此，可以采用本楼层或者跨楼层的迭代绑定算法，消除干扰路测事件点的影响，图5所示为先用一个路测事件点与所有的PRRU位置计算欧式距离，逐点计算；图6所示的为迭代绑定的结果，5次绑定门限，80％的正确绑定率迭代绑定的顺序：PRRU2、PRRU1、PRRU3；
(3)、如果PRRU间距过小，并且PRRU信号受路测人员遮挡时，PRRU点位周围的相同的ESN的路测事件点将会偏向一侧，并且路测事件点偏少，如图7所示，PRRU2和PRRU3左测分别是0_131_1，0_132_1的路测点位数据，此时，可以采用路测相邻关系绑定算法，消除干扰路测事件点的影响，根据路测时间的先后顺序确定未绑定的PRRU位置，确定ESN出现的先后顺序(图7中依次为0_130_1、0_131_1、0_132_1)，按顺序依次绑定PRRU2和PRRU3。
(二)、请参阅图8，本申请实施例提供一种射频头端定位方法，包括：
801、路测终端获取路测事件的测量事件标识及射频头端；
本实施例中，在施工之后，PRRU设计图已经丢失的情况下。在路测终端进行路测过程时，每一次路测事件都临时接入到一个PRRU中，那么就能得到该次测量事件标识以及PRRU，测量事件标识包括TMSI和时间戳，路测终端每一次接入到PRRU都只是单次呼叫，因此每次的接入都会产生一个独有的TMSI，时间戳指的是路测终端每次进行路测事件的时间，TMSI和时间戳可以唯一的指示该路测终端的一此路测事件。
802、路测终端根据测量事件标识得到终端侧测量信息；
本实施例中，路测终端将得到的PRRU位置信息及包含TMSI和时间戳的测量事件标识合并成为终端侧测量信息。
803、网管服务器获取路测事件的网管侧路测信息；
本实施例中，由于每一次路测事件进行时，路测终端临时接入到一个PRRU中，而网管服务器与PRRU是连接的，那么网管服务器也可以获取到路测事件对应的网管侧路测信息，路测事件对应的PRRU记录在网管侧路测信息中，路测事件的TMSI和时间戳记录在网管侧路测信息中，而且路测事件对应的PRRU在接收到路测终端的信号时的接收电平，也记录在网管侧路测信息中。
804、网管服务器根据测量事件标识，将网管侧测量信息和终端侧路测信息进行关联；
本实施例中，由于每一次路测事件时，网管侧测量信息和终端侧路测信息都会记录TMSI和时间戳，那么根据TMSI和时间戳就能将网管侧测量信息和终端侧路测信息进行关联。
805、网管服务器解析终端侧路测信息得到终端位置信息，解析网管侧测量信息得到射频头端的接收电平及射频头端标识；
本实施例中，网管服务器解析终端侧路测信息得到终端位置信息，解析网管侧测量信息得到PRRU的接收电平及ESN。
806、网管服务器根据终端位置信息和射频头端的接收电平，通过场强定位算法计算得到射频头端位置信息；
本实施例中，网管服务器根据终端位置信息和射频头端的接收电平，通过场强定位算法计算得到PRRU位置信息。
807、网管服务器将射频头端标识与射频头端位置信息进行绑定。
本实施例中，网管服务器将射频头端标识与射频头端位置信息进行绑定。
本申请实施例中，虽然定位算法计算出的PRRU位置信息可能存在误差，但是通过采样点的数目和定点测量，可以平滑误差，提升精度。PRRU位置信息用于设备维护，比没有PRRU的位置信息要好很多。

本申请实施例中，在施工阶段，射频头端901的安装位置已经设计好了，那么射频头端设计图上就有射频头端布局信息。在路测终端902进行路测过程时，每一次路测事件都临时接入到一个射频头端901中，那么就能得到该次测量事件标识以及射频头端901，测量事件标识包括TMSI和时间戳，路测终端902每一次接入到射频头端901都只是单次呼叫，因此每次的接入都会产生一个独有的TMSI，时间戳指的是路测终端902每次进行路测事件的时间，TMSI和时间戳可以唯一的指示该路测终端902的一此路测事件。路测终端902在每次路测事件时都能知道接入的射频头端901，而已知射频头端布局信息的情况，可以确定每次路测事件时的射频头端901的射频头端位置信息。路测终端902将得到的射频头端位置信息及包含TMSI和时间戳的测量事件标识合并成为终端侧测量信息。
可选的，本申请的一些实施例中，

网管服务器903，还用于解析终端侧路测信息得到终端位置信息，解析网管侧测量信息得到射频头端901的接收电平及射频头端标识；
网管服务器903，还用于根据终端位置信息和射频头端901的接收电平，通过场强定位算法计算得到射频头端位置信息；
网管服务器903，还用于将射频头端标识与射频头端位置信息进行绑定。
本申请实施例中，在施工之后，射频头端设计图已经丢失的情况下。在路测终端902进行路测过程时，每一次路测事件都临时接入到一个射频头端901中，那么就能得到该次测量事件标识以及射频头端901，测量事件标识包括TMSI和时间戳，路测终端902每一次接入到射频头端901都只是单次呼叫，因此每次的接入都会产生一个独有的TMSI，时间戳指的是路测终端902每次进行路测事件的时间，TMSI和时间戳可以唯一的指示该路测终端902的一此路测事件。由于每一次路测事件进行时，路测终端902临时接入到一个射频头端901中，而网管服务器903与射频头端901是连接的，那么网管服务器903也可以获取到路测事件对应的网管侧路测信息，路测事件对应的射频头端901记录在网管侧路测信息中，路测事件的TMSI和时间戳记录在网管侧路测信息中，而且路测事件对应的射频头端901在接收到路测终端902的信号时的接收电平，也记录在网管侧路测信息中。网管服务器903根据测量事件标识，将网管侧测量信息和终端侧路测信息进行关联。网管服务器903根据终端位置信息和射频头端901的接收电平，通过场强定位算法计算得到射频头端位置信息，将射频头端标识与射频头端位置信息进行绑定，虽然定位算法计算出的射频头端位置信息可能存在误差，但是通过采样点的数目和定点测量，可以平滑误差，提升精度。射频头端位置信息用于设备维护，比没有射频头端901的位置信息要好很多。
