Description

一种实现无线定位的方法、系统及定位位置计算装置 技术领域
本申请涉及无线通信领域，尤指一种实现无线定位的方法、系统及定位位置计算装置。
背景技术
随着时代的不断发展，定位技术受到越来越多的重视，高精度定位需求，尤其是米级定位精度，对无线定位提出了更高的技术要求。
GPS定位技术由于信号损耗等原因，在室内信号变弱的情况下，定位终端将无法搜索到足够的卫星；蜂窝网系统由于定位误差很大，无论在室外还是在室内都无法达到足够的精度，无法满足无线定位需求。
为了解决室内高精度定位问题，需要在地面建立无线定位系统。地面无线定位系统的各个定位信号站在近地布设。建立地面无线定位网络有多种方式，包括采用卫星制式的地面伪卫星系统、无线局域网系统等等。其中，地面伪卫星系统需要手机能够处理地面卫星和太空卫星信号的共存，对其动态范围提出了很大的要求；无线局域网主要采用基于信号强度的测距方法，定位精度严重依赖布设的网路密度，对定位网成本提出了很大要求。
通信网具有良好的覆盖，但由于现有通信网主要面对通信需求，对定位需求研究较少。通信网的定位误差在百米到数千米范围内，无法满足室内外定位需求，因此，通信网在定位领域处于边缘地位。如果通过增加通信网密度来提高定位精度，则会形成较大的网络建设成本，同时增加了网络间干扰。
表1为现有的LTE标准中支持的定位方式(来源：3GPP TS 36.305 V12.0.0(2013-12))；
表1中，A-GNSS：基于导航卫星定位方式，卫星信号接收定位终端测量卫星信号的到达时间，然后根据导航电文信息计算定位终端的位置， 然后通过无线通信传给定位中心；Downlink(下行链路定位方式)：定位终端测量LTE基站下行信号，把测量结果发给定位中心；目前标准中对Downlink定位方式只支持UE-assisted模式，即由UE进行辅助，而由定位中心(E-SMLC)进行定位的模式；ECID(增强小区ID定位方式)，根据小区ID定位，定位精度较低；Uplink(上行链路定位方式)，基站对定位终端的信号进行测量，然后发给定位中心。
Figure PCTCN2015071151-appb-000001
表1
从表1可以看出，除了A-GNSS之外，LTE不支持UE-based定位方式，即在Downlink或Uplink方式下，也必须通过网络，在定位中心(E-SMLC)中实现定位。在通信状况不佳的场景下，如衰落、干扰大等，上述定位模式将无法实现定位终端的定位，因此LTE的定位模式限制了利用LTE系统进行定位的实现。

步骤201、定位测量装置在确定的无线资源上接收通信网带内每个PSS发射的定位信号，获得每个PSS发射的定位信号的时间信息；
这里通信网带内是指在同一通信网络的频带范围内。

定位中心根据所述的每个PSS ID从存储在定位中心自身的PSS信息中查询相应的每个PSS的位置信息、和/或钟差信息；依据每个PSS发射的定位信号的时间信息及查询到的相应的每个PSS的位置信息、和/或钟差信息计算定位测量装置的位置信息。
本发明实施例通过新增的定位方式为Downlink和定位特征为UE-based的定位模式，在能够进行网络连接时，更新本地静态存储的PSS信息和定位模式；在不能进行网络连接时，直接读取本地静态存储的PSS信息和定位模式。由于发射定位信号采用的是广播的方式，不需要通信网的网络资源，在通信网不能进行网络连接时，仍然可以进行定位测量装置的定位。
在LTE的协议标准中，表1已经定义了实现方式和实现特征允许的其他定位模式，本发明实施例新提出了：实现方式为Downlink和实现特征为UE-based＝yes、及实现方式为Downlink和实现特征为UE-based＝no，且UE＝assisted和定位中心E-SMLC-based＝yes的定位模式。表2为包含本发明实施例定位模式的信息表。
和相关技术相比，本发明实施例增加了通过定位测量装置计算自身位置信息的部分。从本发明实施例的方法可见，由于增加了预先设定的定位模式，利用新增定位网元进行定位测量装置的位置计算，提高了定位测量装置的定 位精度；通过定义定位测量装置进行位置计算，增加了定位计算的实现方式。
本发明实施例钟差信息包含：PSS相对参考时钟的钟差信息、和/或PMS之间的钟差信息。
当PSS发射的定位信号已根据参考时钟进行修正，则钟差信息不包含PSS相对参考时钟的钟差信息。
当每个PMS之间的时钟已经被修正，则钟差信息不包含每个PMS之间的钟差信息。

本实施例中，假定定位测量装置的定位信息存储单元没有信息(即上次关机前存储的信息)，且从通信盲点B点(不能收到eNodeB1、eNodeB2、eNodeB3通信信号的区域)移动到A点。假设定位测量装置在B点时开机，且其定位网元信息为空。也可假设定位网元信息为开机前的定位所获得的定位网元信息，本实施例为了说明定位网元信息的请求过程，假设定位网元信息为空。设定的定位模式为：实现方式为Downlink和实现特征为UE-based＝yes。
当定位测量装置在通信盲区B时，由于无法实现通信，因此无法完成自己的定位过程。
当定位测量装置移动到A点时，能够接收到基站信号，假设此时定位测量装置的归属基站为eNodeB1。
下面说明本实施例实现方式为Downlink和实现特征为UE-based＝yes的定位模式执行过程。
定位测量装置通过eNodeB1接入网络，并把归属基站的CELL ID发给E-SMLC，以根据所述CELLID更新本地静态存储的定位网元信息，本实施例具体包括：

根据获得的每个PSS的位置信息及钟差信息，及接收定位信号时获得的每个PSS发射的定位信号的到达时间，定位测量装置计算自身的位置。
本实施例中，由于对定位测量装置的定位请求是定位测量装置本身发起，因此，无需把位置信息发给E-SMLC。
实施例3

图8为本发明第三实施例的网络结构示意图，如图8所示，

当定位测量装置移动到A点时，能够接收到基站信号，假设此时定位测量装置的归属基站为eNodeB3。
下面说明本实施例实现方式为Downlink和实现特征为UE-based＝yes的定位模式执行过程。
定位测量装置在A点时，通过eNodeB3接入网络，并把归属基站的CELL ID发给定位中心(E-SMLC)，根据所述CELLID获得相应的PMS ID，根据PMS ID下载PMS所辖的定位网元信息；本实施例中，下载的定位网元信息有：

PMS2管理下的PSS3的位置信息、钟差信息；PSS4的位置信息、钟差信息；
PMS3管理下的PSS5的位置信息、钟差信息；PSS6的位置信息、钟差信息。
定位测量装置把这些信息在本地进行静态存储(假设为动态定位网元信息)。
当定位测量装置在B点时，不能够接入网络，假设此时定位测量装置仍然能够接收到足够的PSS发过来的定位信号，下面是此时定位测量装置自身发起定位请求时的过程。
定位测量装置检测定位信号，获得所述CELLID相应的每个PMS ID所辖的每个PSS的ID、及每个PSS发射的定位信号的到达时间；本实施例中，定位测量装置检测到每个PMS ID及PSS i(i从1到6)发射的定位信号的到达时间。
根据本实施例的定位模式，定位测量装置根据记录的每个PMS ID及每个PSS ID查找获得每个PSS的位置信息及钟差信息；
本实施例通过PMS ID、PSS ID在动态定位网元信息中检索到PSS i(i从1到6)的位置信息和钟差信息。
根据获得的每个PSS的位置信息及钟差信息，及接收定位信号时获得的每个PSS发射的定位信息的到达时间，定位测量装置计算自身的位置。
本实施例中，由于对定位测量装置的定位请求是终端本身发起，因此，终端无需把位置信息发给E-SMLC。
