具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1，图1是本公开实施例提供的一种终端定位方法的流程图，应用于移动终端，如图1所示，所述方法包括以下步骤：
步骤101、在搜索到位于不同方向的至少两个信号源的情况下，确定所述至少两个信号源中每个信号源的地理位置信息和信号方向，其中，所述信号方向为相对于所述移动终端的方向。
本公开实施例中，所述移动终端可以先搜索附近是否有信号源，在搜索到信号源的情况下，可以进一步确定所搜索到的每个信号源相对于所述移动终端的方向，以判断是否存在位于不同方向的至少两个信号源，若确定存在位于不同方向的至少两个信号源，则确定此时能够依据所述至少两个信号源的相关信息，对所述移动终端进行定位。
具体地，该步骤中，所述移动终端可以全频段扫描附近可用的信号源，若在某个频点或频段上接收到某信号源发射出的信号，则确定搜索到工作于该频点或频段上的一个可用信号源，其中，所述信号源可以是所述移动终端附近的基站、无线路由器、移动终端等设备。
若所述移动终端搜索到位于不同方向的至少两个信号源，则可以分别确定所述至少两个信号源中每个信号源的地理位置信息和信号方向，具体地，所述确定所述至少两个信号源中每个信号源的地理位置信息，可以是通过获 取每个信号源携带的地理标识确定其地理位置信息，更具体地，可以是通过与所述至少两个信号源中每个信号源建立通信连接，然后分别向所述每个信号源发送用于获取该信号源的地理标识的请求消息，各信号源在接收到该请求消息后可以将其已定位的地理标识发送至所述移动终端。需说明的是，若所述信号源为基站、开放式无线路由器等位置确定的设备，则可以直接获取到该信号源的地理标识，若所述信号源为用户移动终端等，则为了确保用户的隐私，可以在用户授权的情况下，获取到该信号源的地理标识。
所述确定所述至少两个信号源中每个信号源的信号方向可以是基于天线阵列方向性变化原理，通过所述移动终端接收每个信号源的发射信号时天线的对应指向来确定该信号源相对于所述移动终端的方向，例如，所述移动终端在接收某信号源的发射信号时，当其天线对准该信号源时，接收到该信号源的发射信号强度最大，这样根据所述天线此时的指向，便可确定该信号源的信号方向。
需说明的是，在所述移动终端具备有效网络的情况下，也可以直接通过联网获取所述移动终端的位置和所述每个信号源的位置，来分别确定所述每个信号源相对于所述移动终端的方向。
可选的，所述方法还包括：
在未搜索到至少两个位于不同方向的信号源的情况下，输出提示消息，其中，所述提示消息用于提示用户当前位置可用信号源不足。
该实施方式中，在所述移动终端未搜索到至少两个位于不同方向的信号源的情况下(包括搜索到的信号源数量少于两个的情况，和搜索到至少两个均位于相同方向的信号源的情况)，可以输出相应的提示消息，以提示用户当前位置可搜索到的信号源数量不足，无法对移动终端进行定位，其中，所述提示消息可以是弹窗文字提醒、语音提醒或动画提醒等多种形式。
这样，在所述移动终端未搜索到至少两个位于不同方向的信号源的情况下，用户可以根据所述提示消息尝试移动所述移动终端的位置，以保证所述移动终端尽可能地搜索到可用于定位的至少两个信号源。
步骤102、根据所述至少两个信号源中每个信号源的地理位置信息和信号方向，确定所述移动终端所处的地理位置。
在确定所述至少两个信号源中每个信号源的地理位置信息和信号方向后，便可基于所述至少两个信号源中每个信号源的地理位置信息和信号方向和不平行直线相交的原理，确定所述移动终端所处的地理位置，具体地，当移动终端接收来自不同方位的信号源的发射信号时，各来自不同方位的发射信号的发射方向必然交汇于同一交点，该交点的位置即为移动终端所处位置，故据此原理，在确定至少两个信号源的地理位置信息和信号方向的情况下，便可通过至少两个信号源中每个信号源的地理位置和信号方向，确定每个信号源对应的信号发射线，其中，每个信号源均位于其对应的信号发射线上，进而可通过至少两根信号发射线的至少一个交点位置，得到所述移动终端所处的地理位置，如将其中某个交点所在的地理位置确定为所述移动终端的地理位置。
且为了便于用户直观地获知所述移动终端的定位位置，可以显示地图定位界面，其中，所述地图定位界面上显示有用于指示所述移动终端所处的地理位置的定位信息，即可根据所定位得到的所述移动终端所处的地理位置，在导航地图上使用用于标识所述移动终端所处位置的定位图标，来指示所述移动终端的具体地理位置。
本公开实施例中，上述移动终端可以是任何具有存储媒介的设备，例如：计算机(Computer)、手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端设备。
本实施例中的终端定位方法，移动终端可以搜索附近的位于不同方向的至少两个信号源，并确定所述至少两个信号源中每个信号源的地理位置信息和信号方向，从而可依据所述至少两个信号源中每个信号源的地理位置信息和信号方向，来对移动终端进行定位，而无需依赖任何有效的运营商网络或无线网络。
参见图2，图2是本公开实施例提供的另一种终端定位方法的流程图，应用于移动终端，本实施例在图1所示的实施例的基础上，对确定所述至少两个信号源中每个信号源的信号方向的步骤进行了细化，使得如何准确地确 定各信号源所在方位的实施方式更为清楚具体。如图2所示，所述方法包括以下步骤：
步骤201、在搜索到位于不同方向的至少两个信号源的情况下，获取所述至少两个信号源中每个信号源的地理位置信息。
该步骤的具体实施方式可以参见图1所示的方法实施例中步骤101的相关实施方式，为避免重复，这里不再赘述。
步骤202、通过所述移动终端的天线分别接收所述至少两个信号源中每个信号源的发射信号。
步骤203、分别将所述每个信号源的发射信号强度最大时所述天线的对应指向确定为该信号源的信号方向。
本实施例中，可以基于波束赋型原理，确定所述至少两个信号源中每个信号源的信号强度和信号方向，具体地，移动终端在接收各信号源的发射信号的过程中，所接收到的发射信号的强度将由于其天线指向的不同而不同，故基于波束赋型原理，当所述移动终端的天线的指向与某信号源所在的方位一致时，所接收到的该信号源的发射信号的强度将最大，而当所述移动终端的天线的指向与该信号源所在的方位不一致时，方向偏离程度越大，所接收到的该信号源的发射信号的强度将越小。因此，可基于所接收到的所述每个信号源的发射信号强度最大时，所述天线的对应指向确定各信号源的信号方向，并可通过检测所述每个信号源的发射信号强度最大时的信号强度，来确定各信号源的具体信号强度。
需说明的是，相关技术中使用4G通信协议的移动终端由于配置的天线数量不多，具备较高的天线传输效率，因此可以不要求必须支持波束赋型通信技术，而对于未来推广使用5G通信协议的移动终端，由于移动终端的尺寸较大，且需布置的天线数量较多，故需要进一步采用波束赋型通信技术来提高天线传输效率，以确保所述终端定位方法的可行性和准确性。
步骤204、根据所述至少两个信号源中每个信号源的地理位置信息和信号方向，确定所述移动终端所处的地理位置。
该步骤的具体实施方式可以参见图1所示的方法实施例中步骤102的实施方式，为避免重复，这里不再赘述。
可选的，所述步骤204包括：
根据所述至少两个信号源中每个信号源的地理位置信息和信号方向，确定所述每个信号源在地图上的位置和信号发射方向；
根据所述至少两个信号源中每两个信号源的信号发射方向的交点，在所述地图上确定所述移动终端所处的地理位置。
该实施方式，为了更准确和直观地显示所述移动终端的定位位置，可以在地图上确定所述每个信号源的位置及其信号发射方向，其中，所述地图可以是未显示在屏幕界面上用于后台确定所述移动终端所处的地理位置的虚拟地图，也可以是显示在屏幕界面上以供用户直观查看所述每个信号源在地图上的位置和信号发射方向的定位地图。
例如，搜索到移动终端附近的信号源A、B、C和D，在地图上确定各信号源的地理位置分布如图3a所示，其中，信号源A的信号发射方向为相对于移动终端偏左α角度，信号源B的信号发射方向为相对于移动终端偏左β角度，信号源C的信号发射方向为相对于移动终端偏左γ角度，信号源D的信号发射方向为相对于移动终端偏右δ角度，各信号源的信号发射方向可分别用直线示意并延长至相交点。
这样，根据所述地图上示意的各信号源的位置和信号发射方向，可以直接得到各信号源的信号发射方向的交点位置，从而可直接将所述交点位置确定为所述移动终端所处的地理位置，例如，如图3a所示，根据各信号源的发射方向的交点T，可确定交点T的地理位置即为所述移动终端的定位位置。
需说明的是，若由于所确定的各信号源的信号发射方向与实际存在一定偏差，而造成在所述地图上得到多个信号发射方向的交点位置时，可以计算其中处于较中心的目标交点位置，并以此作为定位得到的所述移动终端的地理位置。
当然，该实施方式同样可以应用到图1所示的实施例中，且能达到相同有益效果。
可选的，所述根据所述至少两个信号源中每两个信号源的信号发射方向的交点，在所述地图上确定所述移动终端所处的地理位置，包括：
若所述至少两个信号源的数量为至少三个，则确定至少三个信号源中每 两个信号源的信号发射方向的交点，得到至少两个交点；
基于所述至少两个交点中每个交点在所述地图上的位置分布信息，确定目标交点；
将所述目标交点在所述地图上的位置确定为所述移动终端所处的地理位置。
该实施方式中，当所述至少两个信号源的数量为至少三个时，可确定至少三个信号源中每两个信号源的信号发射方向的交点，从而得到至少两个交点，即基于每两个信号源的信号发射方向，便可得到一个交点。
当所述至少两个交点不重合，即得到多个位于不同地理位置(存在一定位置偏差)的交点时，可以基于所述至少两个交点中每个交点在所述地图上的位置分布信息，确定目标交点，具体地，可以基于每个交点在所述地图上的位置分布信息，去掉其中距离多数交点位置较远的交点，得到分布较为集中的交点，然后可以基于一定算法(如工程经验值算法)，计算其中位于最中心位置的目标交点，或者，可以将所述至少两个交点中穿过最多信号发射线的交点作为目标交点，最后将所述目标交点在所述地图上的位置确定为所述移动终端所处的地理位置，这样，可以保证最终确定的目标交点位置与移动终端的真实位置较为接近。
例如，如图3b所示，根据地图上所确定的信号源A、B、C和D的位置和信号发射方向，得到4个交点T1、T2、T3和T4，由于有3个信号源的信号发射方向均穿过交点T1，且T1处于4个交点中较为中心的位置，从而可以定位交点T1在地图上的位置为所述移动终端的地理位置。
本实施例中，通过移动终端的天线接收位于不同方向的信号源的发射信号，将每个信号源的发射信号强度最大时所述天线的对应指向确定为该信号源的信号方向，从而可以保证较为准确地确定各信号源的信号方向，进而可保证终端定位位置的准确性。
另外，本实施例在图1所示的实施例的基础上还增加了多种可选的实施方式，这些可选的实施方式可以相互结合实现，也可以单独实现，且都能达到无需依赖任何有效的运营商网络或无线网络，便可对移动终端进行定位的技术效果。
下面结合图4，对本公开实施例中用户与移动终端的交互实施方式进行举例说明：
步骤401、用户在移动终端上开启终端定位功能。
步骤402、移动终端进入信号源搜索状态，搜索附近带有地理标识的信号源；
其中，当搜索到的信号源数量小于2个时，可以持续搜索，若超过一定时长(如30s)内仍未搜索到超过2个信号源，则执行步骤407。
步骤403、在搜索到至少两个信号源的情况下，分别与搜索到的每个信号源建立连接，并获取所述每个信号源的地理位置信息。
步骤404、确定所述每个信号源相对于移动终端的方向；
其中，在确定不存在至少两个信号源位于不同方向的情况下，执行步骤407。
步骤405、在确定存在至少两个信号源位于不同方向的情况下，根据所获取的所述每个信号源的地理位置信息和所述每个信号源相对于移动终端的方向，确定移动终端当前所处的地理位置。
步骤406、将所确定的移动终端的地理位置显示在地图定位界面上。
步骤407、输出提示消息，以提示用户当前可用于定位的信号源数量不足，需更换位置后重试。

存储器1009可用于存储软件程序以及各种数据。存储器1009可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作***、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器1009可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器1010是移动终端的控制中心，利用各种接口和线路连接整个移动终端的各个部分，通过运行或执行存储在存储器1009内的软件程序和/或模块，以及调用存储在存储器1009内的数据，执行移动终端的各种功能和处理数据，从而对移动终端进行整体监控。处理器1010可包括一个或多个处理单元；可选的，处理器1010可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作***、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器1010中。
移动终端1000还可以包括给各个部件供电的电源1011(比如电池)，可选的，电源1011可以通过电源管理***与处理器1010逻辑相连，从而通过电源管理***实现管理充电、放电、以及功耗管理等功能。
另外，移动终端1000包括一些未示出的功能模块，在此不再赘述。
可选的，本公开实施例还提供一种移动终端，包括处理器1010，存储器1009，存储在存储器1009上并可在所述处理器1010上运行的计算机程序，该计算机程序被处理器1010执行时实现上述终端定位方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
本公开实施例还提供一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，该计算机程序被处理器执行时实现上述终端定位方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。其中，所述的计算机可读存储介质，如只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本公开各个实施例所述的方法。
上面结合附图对本公开的实施例进行了描述，但是本公开并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本公开的启示下，在不脱离本公开宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本公开的保护之内。
