当第一设备确定第一距离大于或等于第一阈值时，执行步骤402-406；当第一设备确定第一距离小于第二阈值时，执行步骤407和411。其中，第二阈值小于或等于第一阈值。
402、当第一距离大于或等于第一阈值时，第一设备向第二设备发送第一指示信息，第一指示信息用于指示第二设备采用第一定位方式。
其中，第一定位方式的定位精度较低，例如第一定位方式可以为基站定位的定位方式或IP地址定位的定位方式。第一定位方式的定位频率可以设置得较低(例如60s/次)，以节省耗电。第一定位方式的定位频率可以是系统默认的，也可以由用户进行设置。
示例性的，如图7所示，用户可以在目标设备的设置界面605点击控件607，如 图8所示，手机检测到用户点击控件607的操作后，手机可以显示目标设备定位方式设置界面801。其中，控件802表示第一距离大于第一阈值(例如，第一阈值为1km)，控件803表示当第一距离大于第一阈值时，采用第一定位方式(例如，基站定位)。控件804表示第一定位方式的定位精度(例如，可以为100m)，控件805表示第一定位方式的定位频率(例如，可以为60s/次)。
如图9中的(a)所示，用户点击控件802后，手机可以显示(下拉)列表控件806，用户可以重新设置(选择)第一阈值。如图9中的(b)所示，用户点击控件804后，手机可以显示(下拉)列表控件807，用户可以重新设置(选择)第一定位方式的定位精度。如图9中的(c)所示，用户点击控件805后，手机可以显示(下拉)列表控件808，用户可以重新设置(选择)第一定位方式的定位频率。
403、第二设备接收第一设备发送的第一指示信息。
第二设备可以通过云服务器接收第一指示信息。即第二设备可以接收云服务器转发的第一指示信息。
404、第二设备采用第一定位方式，并向第一设备发送采用第一定位方式得到的第一定位信息。
其中，第一定位信息用于指示第二设备的第一位置。
405、第一设备接收第二设备采用第一定位方式得到的第一定位信息。
第一设备可以通过云服务器接收第一定位信息。即第一设备可以接收云服务器转发的第一定位信息。
406、第一设备基于第一定位信息以第一显示方式显示第二设备的第一位置。
其中，第一显示方式可以是低精度显示方式，即通过第一显示方式显示的二设备的位置的误差范围较大。例如，可以用一个几何图形表示第二设备的第一位置，第二设备的第一位置的误差范围为100m(米)以内。当然，第二设备的第一位置的误差范围在也可以为50m、200m或300m等等，本申请不做限定。其中，几何图形可以是圆(圈)、椭圆、多边形、扇形或弓形等。
举例来说，如图10所示，手机可以在定位界面601中显示目标设备的图标701、目标设备的位置(目标设备的位置可以用圆圈702表示)和目标设备当前的定位方式703。其中，目标设备当前的定位方式可以为第一定位方式(例如，基站定位)；定位精度可以是100m(以内)，即圆圈702表示的位置的误差范围在100m以内；定位频率可以是60秒(s)/次。手机也可以显示手机用户的图标704以及手机的位置，手机的位置可以显示为一个精确的点或一个圆圈(图10中未示出)，可以视手机的定位方式而定。当然，手机也可以不显示手机用户的图标704，本申请不做限定。
在一种可能的设计中，第一设备基于第一定位信息以第一显示方式显示第二设备的第一位置后，第一设备接收用户对第二设备的位置的第一操作。第一设备响应于第一操作，以第二显示方式显示第二设备的位置，第二显示方式的显示精度大于第一显示方式的显示精度。
示例性的，如图11所示，用户可以点击目标设备的图标701或者圆圈702，手机可以显示功能列表控件706。该功能列表控件706可以包括精确定位控件707。用户可以点击精确定位控件707，手机检测到用户点击精确定位控件707的操作后，手机可 以通知目标设备采用第二定位方式，手机接收目标设备以第二定位方式得到的定位信息，而后，手机以第二显示方式显示目标设备的位置。如图11a中的(a)所示，可以用一个更小的几何图形(例如，更小的圆圈7021)表示目标设备的位置，该圆圈7021表示的位置的误差范围在50m以内；或者，如图11a中的(b)所示，可以用一个点7022来表示目标设备的位置，点7022表示的位置的误差范围可以在5米以内。第二定位方式的定位频率可以保持不变。
可选的，如图11所示，该功能列表控件706还可以包括距离控件708、运动速度控件709、运动方向控件710、历史轨迹控件711和路线控件712等。当用户点击距离控件708时，如图11b中的(a)所示，手机可以显示手机与目标设备的实时距离713。当用户点击运动速度控件709时，如图11b中的(b)所示，手机可以显示目标设备的实时运动速度714。当用户点击运动方向控件710时，如图11b中的(c)所示，手机可以显示目标设备的实时运动方向715(例如，实时运动方向可以用箭头或三角形指示，本申请不做限定)。当用户点击历史轨迹控件711时，如图11b中的(d)所示，手机可以显示目标设备的历史轨迹716(其中，圆圈717可以表示手机初次获取到的目标设备的位置)。当用户点击路线控件712时，手机可以显示从“我的位置”(手机的位置)到“目标设备的位置”的不同出行方式的优选出行方案(例如，公交出行方案(如图11c所示)，骑行(共享单车)出行方案，打车出行方案，自驾出行方案或步行出行方案等)。
可选的，手机每次接收到目标设备根据第一定位方式的定位频率发送的定位信息后，可以震动、发出提示音、闪烁呼吸灯或主动点亮屏幕，以提醒用户目标设备的位置已更新。同时，手机在定位界面601中更新目标设备的位置。
407、当第一距离小于第二阈值时，第一设备向第二设备发送第二指示信息，第二指示信息用于指示第二设备采用第二定位方式。
第二定位方式的定位精度较高，例如第二定位方式可以为卫星定位、Wifi定位、蓝牙定位、传感器惯性定位等定位方式。第二定位方式的定位频率可以设置得较高(例如，10s/次)，以精确定位目标设备。第二定位方式的定位频率可以是系统默认的，也可以由用户进行设置。用户对第二定位方式进行设置的过程可以参考步骤402，在此不做赘述。
需要说明的是，第一定位方式的定位精度小于第二定位方式的定位精度。第一定位方式的定位频率与第二定位方式的定位频率相同或不同。可选的，第一定位方式的定位频率可以小于第二定位方式的定位频率。
在一种可能的设计中，若第二阈值小于第一阈值，当第一距离小于第一阈值且大于第二阈值时，第一设备向第二设备发送第三指示信息，第三指示信息用于指示第二设备采用第三定位方式。其中，第三定位方式的定位精度和第一定位方式的定位精度相同，且第三定位方式的定位频率大于第一定位方式的定位频率；或者，第三定位方式的定位精度和第二定位方式的定位精度相同，且第三定位方式的定位频率小于第二定位方式的定位频率。
408、第二设备接收第一设备发送的第二指示信息。
第二设备可以通过云服务器接收第二指示信息。即第二设备可以接收云服务器转 发的第二指示信息。
409、第二设备采用第二定位方式，并向第一设备发送采用第二定位方式得到的第二定位信息。
其中，第二定位信息用于指示第二设备的第二位置。
410、第一设备接收第二设备采用第二定位方式得到的第二定位信息。
第一设备可以通过云服务器接收第二定位信息。即第一设备可以接收云服务器转发的第二定位信息。
411、第一设备基于第二定位信息以第二显示方式显示第二设备的第二位置。
需要说明的是，第二显示方式的显示精度大于第一显示方式的显示精度，即通过第二显示方式显示的第二设备的位置的误差范围小于通过第一显示方式显示的第二设备的位置的误差范围。例如，可以用一个更小的几何图形(相较于第一显示方式对应的几何图形)表示第二设备的第一位置，或者可以用一个点表示第二设备的第一位置，第二设备的第一位置的误差范围在5m(也可以是1m、2m、3m等等)以内。
如图12所示，手机可以在定位界面601中显示目标设备的图标701、目标设备的位置(目标设备的位置可以用一个点705表示)和目标设备当前的定位方式703。其中，目标设备当前的定位方式可以为第二定位方式(例如，GPS定位方式)，其定位精度可以是5m，即点104表示的位置的误差范围在5m之内，定位频率可以是10s/次。手机也可以显示手机用户的图标704以及手机的位置，手机的位置可以显示为一个精确的点或一个圆圈(图12中未示出)，视手机的定位方式而定。当然，手机也可以不显示手机用户的图标704，本申请不做限定。
基于上述的技术方案，当第一设备与第二设备之间的第一距离大于或等于第一阈值时，第一设备向第二设备发送第一指示信息，以指示第二设备采用第一定位方式；当第一距离小于第二阈值(第二阈值小于或等于第一阈值)时，第一设备向第二设备发送第二指示信息，以指示第二设备采用第二定位方式；其中，第一定位方式的定位精度小于第二定位方式的定位精度，这样，可以避免第二终端设备一直采用高精度的定位方式，能够在定位过程中降低终端的电量消耗，从而降低终端关机的可能性。
下面结合本申请实施例的应用场景及有益效果对本申请实施例提供的定位方法进行介绍。
场景1：主人追踪佩戴具有定位功能的设备(例如，具有定位功能的宠物定位项圈)的宠物。
在野外游玩时，若佩戴具有定位功能的宠物定位项圈的宠物狗走丢了，主人可以在手机的定位APP上定位宠物狗的位置，处理逻辑如下：
假设第二阈值小于第一阈值，第一阈值为1千米，第二阈值为500米。当手机的定位APP判断狗狗与主人之间的距离大于或等于1千米时，如图13中的(a)所示，手机(主人，以图标704表示)可以远程指示定位项圈(宠物狗，以图标701表示)采用第一定位方式(例如，基站定位方式，定位精度为100m)，且每60s上报一次位置信息。当手机的定位APP判断狗狗与主人之间的距离小于1千米且大于500米时，如图13中的(b)所示，手机可以远程指示定位项圈采用第三定位方式，第三定位方式的定位精度与第一定位方式相同(例如，基站定位方式，定位精度为100m)，第三 定位方式的定位频率大于第一定位方式的定位频率(例如，每30s上报一次位置信息)。或者，当手机的定位APP判断狗狗与主人之间的距离小于1千米且大于500米时，如图13中的(c)所示，手机可以远程指示定位项圈采用第三定位方式，第三定位方式的定位精度与第二定位方式相同(例如，GPS定位方式，定位精度为5m)，第三定位方式的定位频率小于第一定位方式的定位频率(例如，每40s上报一次位置信息)。当手机的定位APP判断狗狗与主人之间的距离小于500米时，如图13中的(d)所示，手机可以远程指示定位项圈采用第二定位方式(例如，GPS定位方式，定位精度为5m)，且每10s上报一次位置信息。
这样，避免了因为过度追求定位精度和定位频率而牺牲了定位项圈的工作时长，能够帮助主人尽快找到宠物，避免定位项圈关机导致主人无法找回宠物。
场景2：用户1与用户2通过微信共享位置。
假设用户1和用户2是微信好友，且用户1和用户2都微信在线。用户1在手机上通过微信向用户2佩戴的智能手表发起位置共享，用户2在智能手表上同意位置共享。若第一阈值为1千米，第二阈值等于第一阈值，当手机判断用户1与用户2之间的距离大于或等于1千米时，如图10所示，手机(用户1，以图标704表示)可以远程指示智能手表(用户2，以图标701表示)采用第一定位方式(例如，基站定位方式，定位精度为100m)且每60s上报一次位置信息。当手机判断用户1与用户2之间的距离小于1千米时，如图12所示，手机可以远程指示智能手表采用第二定位方式(例如，GPS定位方式，定位精度为5m)，且每10s上报一次位置信息。并且，手机可以将手机的位置信息发送给智能手表(例如，手机可以每60s或每20s或每10s向智能手表发送一次位置信息)，以便双方共享位置。另外，手机的定位方式可以与智能手表的定位方式相同或不同(例如，当智能手表采用第一定位方式时，手机可以采用第一定位方式或第二定位方式进行定位)。
这样，相比采用高精度的定位方式对目标终端进行多次定位导致目标终端的电量消耗增大，根据距离大小调整定位精度和定位频率可以在尽量靠近目标设备的情况下节省手机和智能手表的定位功耗，尽量避免手机和智能手表自动关机(例如，在寻找佩戴具有定位功能的设备(例如，可穿戴设备)的(走失的)老人或小孩的场景下，尽量靠近目标且保证目标设备不自动关机是特别重要的)。
