实施例二
本实施例中，基站采用3D天线发送数据，终端可以根据接收的信号，将更多的测量信息反馈给基站。由于基站无法获知基站到终端的信道情况，因此，可以采用公用的广播方式发送定位信号。
发送定位信号的基站(此处基站对应于第二传输节点)可以是协作基站，如，协作基站在一个时间周期内n个子帧或子帧组上传输定位信号，n个子帧或子帧组对应多种传输方式，如：协作基站在所述n个子帧或子帧组中采用k个不同波束来发送定位信号，每个波束可以对应一个子帧或子帧组，也可以对应多个子帧或子帧组。其中，k,n均为大于等于2的整数。不同协作基站的n,k值可以相同或不同。
另外，基站(此处基站对应于第三传输节点)可以将定位信号的时频位置发送给终端，终端根据基站发送的定位信号位置信息接收定位信号，确定信号最强的波束，并将波束对应的子帧或子帧组的索引发送给基站(此处基站对应于第一传输节点)。本实施例中，发送定位信号时频位置的基站是终端当前接入的服务基站，该服务基站可以是协作基站也可以不是。本实施例中，将子帧或子帧组的索引发送到的基站是服务基站或协作基站，但本发明并不局限于此。
上述波束情况对于终端也可以是透明的，基站发送定位信号的分组情况，即：哪些子帧对应一个定位信号组，在一个时间周期内一个定位信号组可以对应一个子帧，也可以对应包括多个子帧的一个子帧组，终端接收到定位信号组信息后，终端对同一个定位信号组内的定位信号进行联合接收，将接收到最强信号的子帧或子帧组的索引上报给基站；
终端除了上报子帧或子帧组的索引信息作为定位信息外，还可以上报其它的定位信息，如：接收到的定位信号的强度(功率)、根据定位信号检测 到的时间提前量(TA)值、所述基站到所述终端的路径损失量、与所述基站到所述终端之间信道相关的信道特征信息，如与信道状态匹配的预编码信息、检测到的多径信息和超过阈值的路径数量中一个或多个。
基站将所述终端的定位信息传输给定位服务器，定位服务器根据所述定位信息，结合其它信息如协作基站的地理位置，确定终端的地理位置。定位服务器可以将获得的终端的地理位置传输给核心网或应用服务器或终端。
定位服务器可以利用TA和/或信号强度(路径损失量)确定终端距离相应基站的距离，所述定位服务器根据多个基站和所述终端的距离信息确定所述终端的位置。定位服务器还可以利用预编码信息对应的波束方向信息，或子帧/子帧组索引对应的波束方向信息确定终端对应于基站的角度，再根据多个基站和所述终端的角度信息确定所述终端的位置。定位服务器还可以根据多径信息和/或预编码信息和/或信号强度(路径损失量)，确定基站与终端之间信道的信道特征，再根据已经存储的信道特征与地理位置的映射关系确定所述终端位置。信道特征与地理位置的映射关系可以由终端上报。上述确定终端地理位置的方式可以组合使用，也可以单独使用。
实施例三
本实施例通过建立协助定位系统接入点(AP)与地理位置的映射关系，及终端上报的接入点信息来实现对终端定位。协助定位系统可以是移动通信之外的无线通信系统，如WLAN等。
上述映射关系的建立过程可以包括以下方式，
方式一：
定位服务系统根据接入点上报或者用户上报的信息，建立接入点与关联的物理端口(如作为AP的无线路由器所连接的网口)之间的映射关系；定位服务系统再根据网络布置或网络规划或接入点上报，建立物理端口与地理位置的映射关系。
具体映射关系建立方法，可以设备自动识别确定，也可以手动配置上传，， 也可以通过网络规划统一控制。例如：在AP初始配置时设置当前AP的地理位置，AP自动将其关联的物理端口通过连接的网络上传到定位服务系统，定位服务系统再根据已经建立的物理端口与地理位置的映射关系，确定所述AP对应的地理位置。物理端口和地理位置的映射关系可以在网络布置或规划时建立，也可以在网络建立后进行维护时建立。
方式二：
定位服务系统根据接入点或接入接入点的终端上报的接入点的标识信息及地理位置，直接建立接入点的标识信息与地理位置的映射关系。
除了上述建立方式外，也可以采用其它建立方式。
AP或接入AP的终端通过移动通讯网络或协助定位网络上传上述信息，定位服务系统接收到上述信息后存储，建立AP和地理位置映射关系，用于后续终端定位。
所述接入点信息包括以下至少之一：检索到的k个AP接入点的信息如域名或AP服务器名称、检索到的k个接入点对应的TA值、检索到的k个接入点信号强度等，其中，k为大于等于1的正整数；
所述k个AP接入点的选择具体可以采用以下方式：
所述终端检测到的信号强度最大的k个接入点，k≤K，K为预设值；或者
所述终端检测到的信号强度超过阈值的接入点中信号强度最大的k个接入点，k≤K，K为预设值；
所述终端检测到的信号强度超过阈值的k个接入点，k为实际检测到的信号强度超过阈值的接入点的数目。
所述终端不需要具备接入AP的授权，仅需要具备检测AP的能力，就可以利用已经部署的AP以及所述终端检测到的AP信息，进行定位；
对于具有协助定位系统如wifi功能的移动设备，在移动过程中，搜索可以检测到的协助定位系统接入点(AP)，将搜索到的协助定位系统接入点信息通过移动通信网络(如：LTE网络、3G网络、2G网络)传输给定位服务系统，定位服务系统根据所述终端传递的信息(AP信相关信息)和AP对应 的地理位置信息确定所述终端的地理位置，终端的地理位置可以保存或传递给核心网或应用服务器或终端。在另一实施例中，定位服务系统通过网络将AP和地理位置映射关系传输所述终端，所述终端根据所述映射关系和检测到的AP信息确定自身位置。所述终端确定自身位置后可以位置信息传输给核心网，也可以不传输。
实施例四

所述特殊定位功能具体包括以下至少之一：气压感知功能、温度感知功能、湿度感知功能、风力感知功能、重力感知功能、水压感知功能、特定专有定位信号检测功能等。
所述终端可以直接将上述环境特征信息量化后传输给定位服务系统，也可以将所述信息转化为定位相关信息，如：根据气压确定垂直高度，根据水压确定水深度，根据温度、湿度、风力确定特殊地理环境(如在室内还是室外、在平原还是山区)。
所述特定专有定位信号检测功能包括：提供区域定位的服务商，将位于该服务区域的终端的位置信息传递给终端，终端再通过网络传递给定位服务系统，其中，所述位置信息可以是具体地理位置信息，也可以是部分地理位置信息，如：水平位置或垂直位置等。所述定位服务系统可以利用这些信息进行综合判断，最终确定终端位置；
实施五
终端可以具备上述实施例二到实施例四中一种或多种功能，当终端接入网络时，将自身具备的功能上报给接入的基站，基站传输给定位服务系统， 定位服务系统收到后，可以配置所述终端上报的定位信息类型并通过传输节点发送给终端，所述终端根据相关配置确定上报的定位信息类型。基站也可以不获取终端的能力，而是直接下发配置信息给终端，终端根据其能力选择性的进行上报。
上报的定位信息类型可以是一种或多种类型，具体组合可以参考上述实施例中提到的定位信息(如TA、子帧索引或子帧组索引、预编码信息、信号强度信息、多径信息、AP信息、特殊功能模块提供的环境特征信息等)进行任意组合，下面仅是一种示例，不限于下述描述，上报的定位信息类型的数目可以是2、3、4、5等值，如：
上报两种定位信息类型：TA和子帧索引(子帧组索引)，或者，TA和预编码信息，或者，TA和信号强度信息，或者，TA和多径信息，或者，AP信息和TA，或者，AP信息和环境特征信息。
