Description

一种定位方法及装置
本申请要求在2016年7月22日提交中国专利局、申请号为201610587182.6、发明名称为“一种定位方法及装置”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，尤其涉及一种定位方法及装置。
背景技术
在窄带物联网(Narrow Band Internet of Things，NB-IOT)的应用场景中，经常需要获得终端设备当前的位置信息。比如，在智能仓储与配送过程中，需要跟踪终端设备当前的位置信息。NB-IOT支持大量终端设备的接入，其中有些终端设备可能固定不动，有些终端设备会不断移动。
在目前的上行到达时间差(Uplink Time Difference of Arrival，UTDOA)定位方法中，由网络侧测量实体(Location Measurement Unit，LMU)测量移动终端信号到达的时间。该方法要求至少有三个LMU参与测量，每个LMU测量移动终端发射信号的到达时刻。LMU可以和基站结合在一起，也可以分开放置。每个LMU的地理位置是已知的，因此可以利用球面三角算出移动终端的位置。
在NB-IOT的某些应用场景下对定位精度要求较高，但NB-IOT中的终端设备一般要求低复杂度、低功耗，需要尽量减少定位对终端设备的影响。另外，终端设备可能处于弱覆盖下(如某地下室)，终端设备与网络侧设备之间的信道可能衰减比较大，不利于提高定位精度。
综上，目前在对终端设备进行定位时存在定位精度低、对终端设备的功耗大的问题。

收发机，用于在处理器的控制下接收和发送数据。
本申请实施例可以利用在被定位终端设备周围的固定终端设备接收被定位终端设备发送的目标信号，并基于接收到的目标信号确定定位信息，网络侧设备可以基于固定终端设备上报的定位信息对被定位终端设备进行定位。由于在被定位终端设备周围的固定终端设备与该被定位终端设备之间的距离较近，因此其对目标信号的测量结果较准确，从而可以提高对被定位终端设备的定位精度。
进一步的，由于被定位UE不需要连续监听信号，并发送测量结果，而只需要发送定位信号；同时，被定位UE与定位UE之间距离较近，所需发送功耗少，因此还可以降低终端设备的功耗。

具体实施方式
本申请实施例可以利用固定终端设备对被定位终端设备(例如，可以为移动终端)进行定位，如图1所示，固定终端设备作为定位测量实体，接收被定位终端设备发送的目标信号，并将测量后的定位信息发送给网络侧设备进行定位。
下面结合说明书附图对本申请实施例作进一步详细描述。
实施例一
如图2所示，为本申请实施例一提供的定位方法流程图，包括以下步骤：
S201：被定位终端设备生成用于固定终端设备监听的目标信号。
这里，固定终端设备(例如：用户设备(User Equipment，UE))监听的目标信号可以包括预设的定位信号和设备与设备之间通信的信号中的至少一种。预设的定位信号包括以下信号中的至少一种：预设的物理层信令，其中包括该被定位终端设备的标识信息；预设的媒体接入控制(Media Access Control，MAC)层信令，比如MAC层控制单元(Control Element，CE)，比如可以沿用图3所示的边通信共享信道(Sidelink Shared Channel，SL-SCH)MAC协议数据单元(Protocol Data Unit，PDU)，其中可以不包含任何的服务数据单元(ServiceDataUnit，SDU)，也即载荷(payload)为0；预设的高层信令，比如在设备到设备(Device-to-Device，D2D)发现(discovery)信号中，添加用于定位的标识，或者用于定位的业务类型。设备与设备之间通信的信号可以包括D2D发现信号和D2D通信消息中的至少一种。除此之外，还可以包括车与车(Vehicle to Vehicle，V2V)之间通信的信号，车与万物(Vehicle-to-Everything，V2E)之间通信的信号等物联网中的任何实体之间通信的信号。
在具体实施过程中，被定位终端设备可以在接收到网络侧设备发送的定位请求(该定位请求可以携带在寻呼消息中或专用的请求定位的消息中)后，再生成用于固定终端设备监听的目标信号。
网络侧设备可以在发送的定位请求中携带用于定位的目标信号的信号类 型，比如D2D发现信号或D2D通信消息等，以便被定位终端设备基于该信号类型发送目标信号。
本申请实施例中的网络侧设备可以是基站(evolved Node B，eNB)等网络侧设备。
S202：被定位终端设备发送目标信号。
具体实施过程中，被定位终端设备可以根据网络侧设备指示的信号发送资源发送目标信号，具体地，可以接收网络侧设备通过专用信令发送的用于发送目标信号的信号发送资源；或者，接收网络侧设备广播的信号发送资源池，从该信号发送资源池中选择(随机选择或者按照预设的规则选择)用于发送目标信号的信号发送资源。
这里，网络侧设备可以为每个被定位终端设备配置信号发送资源；并将为每个被定位终端设备配置的信号发送资源发送给该被定位终端设备。或者，为各个被定位终端设备配置信号发送资源池，然后广播信号发送资源池，被定位终端设备从信号发送资源池中选择用于发送目标信号的信号发送资源。
S203：固定终端设备监听被定位终端设备发送的目标信号。
在具体实施中，固定终端设备可以根据网络侧设备发送的(优选单播或多播的方式，也可以是广播的方式发送)被定位终端设备的标识信息和/或目标信号的信号类型监听目标信号。目标信号的信号类型比如D2D发现信号或D2D通信消息，还可以是具体通信信号的类型，比如语音信号、数据信号等。
这里，若目标信号是预设的定位信号(特定的专用于定位的信号)，固定终端设备可以通过监听预设的定位信号来确定对被定位终端设备进行定位的定位信息。若目标信号是设备与设备之间通信的信号，为了缩小监听范围，网络侧设备可以向固定终端设备指示具体需要监听的被定位终端设备或者指示目标信号的信号类型。当然，在目标信号是预设的定位信号的情况下，网络侧设备仍可以向固定终端设备指示具体需要监听的被定位终端设备，以进一步缩小监听范围。
在具体实施过程中，固定终端设备根据网络侧设备发送的信号接收资源， 监听被定位终端设备发送的目标信号，具体地，固定终端设备接收网络侧设备发送的(具体可以是通过广播的形式发送)用于监听目标信号的信号接收资源(用于接收一个或多个被定位终端设备发送的目标信号)；或者，固定终端设备根据网络侧设备发送的对应不同信号类型的信号接收资源(比如通过广播的形式发送)，以及网络侧设备发送的待监听的目标信号的信号类型(比如通过单播或多播的形式发送)，确定用于监听目标信号的信号接收资源。
S204：固定终端设备基于监听到的目标信号，确定用于对被定位终端设备进行定位的定位信息。
在具体实施中，固定终端设备首先确定自身被激活为定位测量实体，之后再启用作为定位测量实体的定位功能。具体地，固定终端设备可以根据以下方式中的至少一种确定自身被激活为定位测量实体：
1)固定终端设备在开机后作为所述定位测量实体。
2)固定终端设备在接收到网络侧设备发送的激活指令后，确定自身被激活为定位测量实体；这里，网络侧设备可以根据终端设备是否固定、是否具有目标信号接收能力、目前是否有定位需求等来发送激活指令。该激活指令可以是网络侧设备通过专用信令下发的，具体地，网络侧设备可以将该激活指令，以及被定位终端设备的标识信息和/或信号类型一起通过专用信令下发给固定终端设备。
3)固定终端设备接收网络侧设备发送的(比如通过广播的形式发送)激活条件(比如是否处于覆盖增强区域、是否位于预设的区域范围内等)，在确定自身符合所述激活条件后，确定自身被激活为定位测量实体。
固定终端设备确定的定位信息中可以包括固定终端设备和被定位终端设备的标识信息，以及以下信息中的至少一种：
1)固定终端设备接收目标信号的时间；
2)固定终端设备接收目标信号与所述被定位终端设备发送所述目标信号之间的时间差；
3)固定终端设备测量到的目标信号的接收信号强度。
S205：固定终端设备将确定的定位信息发送给网络侧设备。
这里，如果固定终端设备当前并未与网络侧设备建立连接，可以触发进入连接态并发送定位信息给网络侧设备；也可以记录定位信息，待下次进入连接态后再发送给网络侧设备。
S206：网络侧设备基于所述定位信息，确定所述被定位终端设备的位置。
在具体实施过程中，网络侧设备确定被定位终端设备的位置的方式可以有多种。比如，可以基于多个固定终端设备发送的定位信息，确定各个固定终端设备接收目标信号与被定位终端设备发送所述目标信号之间的时间差，并根据已知的各个固定终端设备的位置信息，计算得到被定位终端设备的位置信息(基于UTDOA定位原理)。或者，根据各个固定终端设备接收目标信号的接收信号强度，确定与被定位终端设备最接近的固定终端设备，根据接近定位原则，将与被定位终端设备最接近的固定终端设备的位置确定为被定位终端设备的位置。或者，根据测量到的目标信号的接收信号强度(比如参考信号接收功率(Reference Signal Receiving Power，RSRP)，结合已知的固定终端设备周围的信号强度分布图(也即从固定终端设备周围各个位置点到达固定终端设备的接收信号强度分布)，确定被定位终端设备的大致位置。或者，根据测量到的接收信号强度，估计被定位终端设备与多个固定终端设备之间的距离，并结合已知的多个固定终端设备的位置信息，确定被定位终端设备的位置信息。
上述实施例可以利用在被定位终端设备周围的固定终端设备接收被定位终端设备发送的目标信号，并基于接收到的目标信号确定定位信息，网络侧设备可以基于固定终端设备上报的定位信息对被定位终端设备进行定位。由于在被定位终端设备周围的固定终端设备与该被定位终端设备之间的距离较近，因此其对目标信号的测量结果较准确，从而可以提高对被定位终端设备的定位精度，并且可以降低终端设备的功耗。
下面通过两个具体的示例对本申请思想做进一步说明。
实施例二
如图4所示，为本申请实施例二提供的定位方法流程图，包括以下步骤：

这里，被定位终端设备发送目标信号的信号发送资源可以是网络侧设备通过专用信令配置的，也可以是从网络侧设备广播的发送资源池中，随机或基于预设的规则选择出来的。
S403：被激活为定位测量实体的固定终端设备监听被定位终端设备发送的目标信号，确定定位信息。

S501：网络侧设备向被定位终端设备发送定位请求。该定位请求可以携带在网络侧设备发送的寻呼消息中，或者网络侧设备也可以发送专用的请求定位的消息。
该定位请求可以包含用于定位的目标信号的信号类型，以便被定位终端设备基于该信号类型发送目标信号。
作为一种可选的实施方式，网络侧设备在需要对被定位终端设备进行定位时，若发现该被定位终端设备正在发送或者将要发送设备与设备之间通信 的信号，比如D2D discovery消息，D2D通信communication消息，则网络侧设备可以不用发送定位请求，直接进入S503。
