Description

辅助定位的方法及装置 技术领域
本发明涉及通信技术领域，具体而言，涉及一种辅助定位的方法和一种辅助定位的装置。
背景技术
移动业务的快速发展极大地改变了人们的生活。据统计，大部分的业务量是在室内的场景下产生的，在室内的场景下如何实现精准的定位是提供移动服务的关键。
室内定位技术在实际应用中有着很大的需求，至少体现在以下方面：
1)公共安全服务：在发生重大的安全事故，如火灾的场景下，精准的室内定位可以使得救援服务更加的有效；
2)室内导航：在一个不熟悉的场所，精准的室内定位可以使得用户更加快捷的寻找所需，如空闲的车位、超市中需要购买的物品；
3)其他社会活动，如室内的市场推广等。
在3GPP Rel-9协议的制定过程中，研究了定位技术，确定了三种定位技术，分别是OTDOA(Observed Time Difference of Arrival，观察到达时间差)，A-GNSS(Assisted-Global Navigation Satellite System，辅助全球导航卫星系统)，E-CID(Enhanced Cell-ID positioning method，增强的小区ID定位方法)的方法，运营商可以根据小区覆盖，定位精度等方面选择其中的一种或是几种来实现定位。
对于OTDOA技术，主要的定位的基本思想是：UE(User Equipment，用户设备)根据eNodeB(基站)的下行参考信号，测量不同eNodeB的信号到达UE的时间差。根据UE测量结果，并结合eNodeB的坐标，采用合适的位置估算方法。一般位置估算方法至少需要考虑3个eNodeB定位的情况，UE测量的eNodeB的数据越多，测量精度越高，定 位性能的改善也越明显。
对于E-CID技术，在TDD(Time Division Duplexing，时分双工)系统中，当eNodeB采用小间隔天线阵列的智能天线时，可以估计出UE信号到达eNodeB的到达角度(AoA，Angel of Arrival)，因此可以估计出UE在小区中所处的方位。同时，根据eNodeB和UE测量所得到的UE信号发射相对于其接收的时间提前量(TA，Timing Advance)，可以估计出UE与eNodeB之间的传播距离。这样，综合AoA和TA测量结果，基于单个小区就可以进行UE定位。
对于A-GNSS技术，就是基于UE所接收到的若干卫星信号进行相关测量，然后进行UE定位。
但是，对于上述的三种定位的技术，在室内的场景下都会有一定的局限性，具体如下：
对于A-GNSS技术，在室内的场景下，受限于穿透损耗以及室内传播的复杂性，导致在室内收到的卫星信号会比较受限，影响定位精度；
对于E-CID技术，定位精度比较低，无法满足室内定位所需要的亚米级别的定位精度要求；
对于OTDOA技术，终端需要能够接收到至少3个基站的定位信号，在室内的场景下同样是难以实现的。
因此，如何能够有效提高室内场景下的定位精度成为亟待解决的技术问题。
发明内容
本发明正是基于上述技术问题至少之一，提出了一种新的辅助定位的方案，可以根据实际应用场景的需求合理布置辅助定位源来实现对其它终端的辅助定位，有效提高了其它终端在特殊场景下的定位精度。

在该技术方案中，由于在某些特殊场景下，如室内场景，终端与基站之间的通信会受到一定的局限性，因此通过由指定终端与基站和/或核心网建立连接，构成基于指定终端的微小区基站，以辅助其它终端进行定位，使得能够根据实际需求合理布置辅助定位源(如微小区基站)来实现对其它终端的辅助定位，有效提高了其它终端在特殊场景下(如室内场景下)的定位精度，解决了在某些特殊场景下由于基站与终端之间的通信受限而影响定位精度的问题。
在上述技术方案中，优选地，辅助所述其它终端进行定位的步骤具体包括：所述指定终端发送用于所述其它终端识别所述指定终端的信号，并向所述其它终端发送用于定位的导频。
在上述任一技术方案中，优选地，还包括：根据定位精度的需求，调整向所述其它终端发送的所述导频的导频图案。
具体来说，若定位精度要求较高，则可以向其它终端发送较为密集的导频图案；相反地，若定位精度要求较低，则可以向其它终端发送较为稀疏的导频图案。
在上述任一技术方案中，优选地，所述指定终端在基于协调的时频资源、预定义的时频资源或所述基站和/或核心网通知的时频资源上发送所述导频和用于所述其它终端识别所述指定终端的信号。

在上述任一技术方案中，优选地，所述指定终端在预定义的资源上或在指定的资源段上进行扫描，以确定是否接收到所述定位请求。
在上述任一技术方案中，优选地，还包括：所述指定终端通过GPS(Global Positioning System，全球定位系统)、空中接口或有线的回传链路进行自身定位。
根据本发明的第二方面，还提出了一种辅助定位的方法，包括：待定位终端发送定位请求；接收终端化小区针对所述定位请求发送的响应信 号，以由所述终端化小区辅助所述待定位终端进行定位。
在该技术方案中，由于在某些特殊场景下，如室内场景，终端与基站之间的通信会受到一定的局限性，因此通过接收终端化小区对定位请求发送的响应信号，以由终端化小区辅助待定位终端进行定位，使得能够根据实际需求合理布置辅助定位源(如微小区基站)来实现对其它终端的辅助定位，有效提高了其它终端在特殊场景下(如室内场景下)的定位精度，解决了在某些特殊场景下由于基站与终端之间的通信受限而影响定位精度的问题。
在上述任一技术方案中，优选地，由所述终端化小区辅助所述待定位终端进行定位的方法具体包括：所述待定位终端确定包含多个所述终端化小区的集合；基于所述集合中的终端化小区发送的用于定位的导频，进行定位。
具体地，待定位终端可以根据定位精度的要求确定集合中的终端化小区的数量，如定位精度要求较高，则将数量较多的终端化小区加入到集合中，如定位精度要求较低，则将数量较少的终端化小区加入到集合中。
在上述任一技术方案中，优选地，根据接收到的所述终端化小区发送的所述响应信号的强度确定所述集合。具体地，可以将响应信号的强度较大的几个终端化小区加入到集合中。

综上所述，本发明的技术方案主要是提出了一种通过具备基站功能的终端辅助其它终端进行定位的方法，可以有效的改善室内场景下的定位精度。
具体流程如图5所示：
首先，T-SC(Terminal based-small cell，终端化小区)通过GPS，空口或是有线的backhaul实现自身的定位，需要注意的是在同一个区域内的不同的T-SC之间可能需要实现同步。
需要定位的终端502开启定位请求，当终端502由于业务的需求，需要实现定位功能的时候，终端502可以执行步骤506，即发送定位请求。发送定位请求的资源可以是预先定义的或是预先配置给终端502的。
T-SC 504在预定义的资源上扫描，确定是否接收了来自于终端502的定位请求。T-SC 504需要预先知道定位请求所占用的资源，可以通过交互信息来获知这个消息。或者T-SC 504可以通过在某个频段上进行扫描来获知是否存在定位请求。
T-SC 504在收到来自终端502的定位请求之后，将会进入到“基站”的模式，并执行步骤508，即发送同步信道、系统信息以及导频等信息以便需要定位的终端502可以识别到该T-SC 504。
终端502确定可以用于辅助定位的T-SC 504的集合。选择T-SC 504的原则可以是基于接收到的T-SC 504的信号强度或是其他可能的方法来实现。用于辅助定位的T-SC 504的集合是可以更新的，比如可以根据终端的移动来动态的选择辅助定位的T-SC 504的集合
T-SC 504执行步骤510，即发送定位导频，定位导频的导频图案可以复用目前的已有的导频图案，或是基于定位精度要求较高的时候，T-SC504可以在时频位置上发送更加密集的用于定位的导频图案。
终端502基于周围辅助的T-SC 504以及可能的其他基站的定位导频信号来实现定位。
具体地，如图6所示，位于室内的终端602由于较强的穿透损耗，无 法接收到来自于宏基站(如图6中所示的宏基站604A、604B、604C和604D)的定位信号，那么临近房间的T-SC(如图6中所示的T-SC 606A、606B和606C)可以开启基站功能，发送定位导频来为该终端602实现定位功能。需要注意的是，当终端602可以接收到来自于宏基站或是其他small cell的定位导频时，终端602也可以基于宏基站或是其他small cell发送的定位导频进行室内定位。同时可以根据定位精度的要求，来要求更多的T-SC来加入到辅助定位的集合或是要求发送更加密集的定位导频。
本发明的技术方案可以有效解决在室内传播环境较为复杂的情况下，终端利用传统的方法无法实现精准定位的问题。
以上结合附图详细说明了本发明的技术方案，本发明提出了一种新的辅助定位的方案，可以根据实际应用场景的需求合理布置微小区基站来实现对其它终端的辅助定位，有效提高了其它终端在特殊场景下的定位精度，解决了在某些特殊场景下由于基站与终端之间的通信受限而影响定位精度的问题。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
