具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本申请实施例的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义理解， 所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本申请实施例中的具体含义。本申请实施例中，“进一步地”、“示例性地”或者“可选地”等词用于表示作为例子、例证或说明，不应被解释为比其它实施例或设计方案更优选或更具有优势。使用“进一步地”、“示例性地”或者“可选地”等词旨在以具体方式呈现相关概念。
本申请实施例可以应用于各种通信系统，例如：全球移动通讯(GlobalSystem of Mobile communication，GSM)系统、码分多址(Code Division MultipleAccess，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long TermEvolution，LTE)系统、LIE-A(Advanced long term evolution，先进的长期演进)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、5G、超5代(Beyond Fifth Generation，B5G)、第6代(6th Generation，6G)系统等，本申请实施例并不限定。
本申请实施例的目标终端可以是能够和基站进行通信的设备。目标终端可以是任意一种具有无线收发功能的设备，包括但不限于：手机、平板电脑、移动电脑、电子手环、电子手表、智能穿戴设备、智能汽车等，本申请实施例并不限定。
本实申请施例的基站可以是能和目标终端进行通信的设备。基站可以是任意一种具有无线收发功能的设备。包括但不限于：基站NodeB、演进型基站eNodeB、5G通信系统中的基站、未来通信系统中的基站、WiFi系统中的接入节点、无线中继节点、无线回传节点等。基站还可以是云无线接入网络(Cloud Radioaccess Network，CRAN)场景下的无线控制器；基站还可以是小站，传输节点(Transmission Referencepoint，TRP)等，本申请实施例并不限定。
目前对目标终端的定位主要依靠卫星导航系统。通过卫星导航系统能够准确对户外/室外目标终端进行定位，但是当目标终端位于室内环境时，依靠卫星导航系统则难以获得目标终端的位置信息，即无法实现对目标终端的定位。
为详尽阐述本技术方案，以GPS定位系统、用户终端(User Equipment，UE)为例，对相关技术中的定位方法做进一步解释说明。
图1是通过GPS定位系统对用户终端进行定位的示意图。如图1所示，用户终端100在室外环境中，并能接收GPS定位系统200的信号。通过定位信号利用测距交会方法实现对用户终端100的定位。
图2是用户终端在室内场景如商场或地下停车场的示意图。如图2所示，用户终端100在室内环境中，难以接收到GPS定位系统200的定位信号，因此难以获取用户终端100位置信息。
图3是多基站协同对用户终端进行定位的示意图。如图3所示，为弥补卫星导航系统难以对室内用户终端进行定位的不足，相关技术采用多个基站协同实现对用户终端的定位。该方式虽然能够对位于室内的用户终端进行定位，但该定位方法需要通过多个基站，如图3所示的三个基站300协同作业，且还要求多个基站时间精准同步。为实现对室内用户终端的精准定位还要求三个基站300和用户终端100之间都是视线(Line Of Sight，LOS)环境。由此可知，多基站协同对用户终端进行定位有着严格的条件，在实际的蜂窝网络中，难以都满足。
本申请实施例提供了一种定位方法、定位装置、定位系统、定位设备、计算机可读存储 介质及计算机程序产品，通过分析基站、智能反射面(Reconfigurable Intelligent Surface，RIS)以及目标终端之间的到达角，从而得到目标终端的定位信息，不仅能够实现对位于室内环境的目标终端进行定位，还能够降低为获得定位信息的条件和提高定位准确度。
下面结合附图，对本申请实施例作进一步阐述。
图4是本申请一实施例提供的用于执行目标终端定位方法的系统架构示意图。如图4所示，该定位系统架构包括目标终端如用户终端100，基站300，智能反射面500，位置管理功能(Location Management Function，LMF)装置。
用户终端100，即需要被定位的目标终端，能够与基站300、智能反射面500通信连接。
基站300，能够与用户终端100、智能反射面500通过有线或无线方式进行通信连接。
智能反射面500，亦称重构智能表面或智能超表面，由智能反射单元阵列组成，每个智能反射单元能够独立地对入射信号进行某些改变。智能反射面500，通过在平面上集成许多无源反射单元，调节反射单元的相位，可以智能地调整无线网络环境，提升无线通信网络的覆盖性能，且具有低功耗、易部署等特点。智能反射面500可以是一个或一个以上。
位置管理功能装置，亦称定位管理功能装置，能够设置在定位服务器400中，也可以集成设置在用户终端100或基站300中。
当基站300和用户终端100存在视线径，定位服务器400通过获取基站300、智能反射面500的位置信息、用户终端100相对于智能反射面500的到达角信息以及用户终端100相对于基站300的到达角信息，可以得到用户终端100的位置信息。
