换句话说，定位服务器并没有广播下发定位扫描请求消息，有参与众包的终端(相邻终端)来完全控制广播消息的发送的周期等，本发明实施例中有用户决定是否开进短距通信方式并发送广播消息，由于定位服务器不需要触发广播消息的下发，所以，这里面，需要请求定位的移动终端通过请求消息直接将扫描的信息上报，这里可以理解为该信息上报与定位请求合并成了一条消息，发送给定位服务器。
可选地，作为另一实施例，在230中，定位服务器可以根据可信度验证信息的数量的多少确定相邻终端的位置信息的可信度的高低，其中，可信度验证信息的数量越多，对应相邻终端的位置信息的可信度越高，可信度验证信息的数量越少，对应相邻终端的位置信息的可信度越低。
例如，可信度验证信息能够提供一个供定位服务器验证其可信度的验证证据信息。该可信度验证信息可以是用户输入或者用户选择的，也可以是通过相邻终端自动收集相关位置证据获得的。当可信度验证信息是用户输入或者用户选择的时候，相邻终端可以将其收集的能够用于证明其有效位置的数据呈现给用户，获取用户的选择，或者直接获取用户自己的手动输入的可信度验证信息。例如，当用户正在深圳坂田万科城丹桂轩吃自助，那么以下几种都可以作为可信度验证信息，第一种，全球定位系统(简称GPS，英文Global Positioning System)或辅助全球卫星定位系统(简称A-GPS，英文Assisted Global Positioning System)模块定位出来的用户大概位置；第二种，大众点评或美团等上面的消费记录等；第三种，用户主动拍摄的具有明显地理位置信息的实时图像或视频。应理解，可信息度验证信息包括至少上述一种情况。
如果相邻终端上报的可信度验证信息是一个室内封闭环境的明显的商家标志(图片或视频)，并且还有其他的可信度证据信息，比如消费记录、通过GPS证明其所在的大概位置，并且在可信度验证的数据库中大概位置 范围内，只有这样一个商家标志(图片或视频)，那么该用户提供的众包位置数据的可信度就很高，可以认为其能够提供的定位精度响应的也比较高，可以赋给其上报的位置以较高的可信度值，例如，其可信度指数为100。在例如，如果相邻终端提供的可信度验证信息仅有一张商家的店内的图片，则该相邻终端的位置可信度就会相对较低，例如，其可信度指数为1。换句话说，定位服务器可以根据相邻终端提供的位置可信度证据的多少确定可信度的大小。例如，可以设置可信度指数为1-100，数值越大表示位置信息的可信度越高，表示位置信息越精确。当然，为了定位算法的使用，也可以采用其他方式来表示可信度的高低，比如采用指数映射方式。可信度指数抽象出来以后，可以作为定位算法的系数或者指数来修正定位的精度。
可选地，作为另一实施例，在240中，定位服务器根据可信度的高低和广播消息的RSSI值确定相邻终端的位置信息的权重；
定位服务器根据权重和相邻终端的位置信息确定定位终端的位置信息。
例如，定位服务器在确定定位终端的位置时，可以将可信度高和RSSI值高的位置信息设置高的权重，将可信度低和RSSI值高的位置信息设置低的权重确定定位终端的位置信息，例如，可以采用三角定位法或质心定位法等来确定定位终端的位置信息。
可替代地，作为另一实施例，本发明实施例方法还包括：
定位服务器接收定位终端发送的反馈信息，反馈信息表示定位终端的位置信息是否准确；
定位服务器根据反馈信息调整相邻终端的位置信息的可信度。
具体地，定位终端接收定位服务器发送的位置信息后，可以根据该位置信息是否准确进行反馈，产生反馈信息，并向定位服务器发送，定位服务器收到反馈信息后，根据反馈信息调整相邻终端的位置信息的可信度。例如，当反馈信息表示定位终端的位置信息较准确时，服务器可以根据反馈信息调高相邻终端的位置信息的可信度，当反馈信息表示定位终端的位置信息不准确时，服务器可以根据反馈信息调低相邻终端的位置信息的可信度。
上文中结合图2从定位服务器的角度描述了本发明实施例的定位的方法，下面结合图3从定位终端的角度描述本发明实施例的定位的方法。
图3是根据本发明一个实施例的定位方法的示意流程图。图3的方法由定位终端执行，具体地，如图3所示的方法，包括：

换句话说，定位终端向定位服务器发送定位请求消息，定位请求消息可以携带定位终端的标识信息，定位请求消息用于触发服务器根据定位终端的至少一个相邻终端的位置信息和可信度验证信息确定定位终端的位置信息，其中，至少一个相邻终端中的每一个相邻终端的可信度验证信息用于定位服务器确定该每一个相邻终端的位置信息的可信度，可信度表示至少该每一个相邻终端的位置信息的精确程度。
320，定位终端接收定位服务器发送的定位终端的位置信息。
应理解，定位终端可以为具有无线通信功能的用户设备，相邻终端为该定位终端短距通信范围内的终端，其中，短距通信方式包括蓝牙、WIFI或红外等，相邻终端包括至少一个终端。
具体地，定位终端需要定位时，会向定位服务器发送定位请求，之后，定位服务器通过获取定位终端的相邻终端的位置信息和可信度验证信息，根据可信度验证信息确定出相邻终端的位置信息的可信度，可信度表示相邻终端的位置信息的精确程度；定位服务器根据相邻终端的位置信息和可信度确定定位终端的位置信息，定位服务器向定位终端发送定位终端的位置信息。
因此，本发明实施例通过定位服务器获取定位终端的相邻终端的位置信息和可信度验证信息，进而确定出相邻终端的位置信息的可信度，并根据相邻终端的位置信息和可信度确定出定位终端的位置信息，能够提高定位精确度。
应理解，定位服务器可以根据相邻终端的位置信息和可信度采用三角定位法、质心定位法等来方法确定出定位终端的位置。本发明实施例对具体定位算法不作限定。

具体地，在定位终端向定位服务器发送定位请求后，定位服务器会向相邻终端发送定位扫描请求消息，定位扫描请求消息用于指示相邻终端接收定位终端发送的定位消息，例如，定位终端通过持续广播的形式发送定位消息，该定位消息中可以携带定位终端的标识，相邻终端接收到定位扫描请求消息后会自动通过短距网络接收定位终端发送的定位消息，相邻终端收到定位消息后，相邻终端根据定位消息生成扫描报告消息，扫描报告消息携带定位消息的RSSI值、相邻终端的位置信息和可信度验证信息，定位终端将该扫描报告消息发送至定位服务器，定位服务器根据扫描报告消息获取定位消息的RSSI值、相邻终端的位置信息和可信度验证信息，定位服务器根据定位消息的RSSI值、相邻终端的位置信息和可信度验证信息确定定位终端的位置信息，并将该位置信息发送至定位终端。
或者，定位服务器不会向相邻终端发送定位扫描请求消息，具体地，在定位终端向定位服务器发送定位请求后，定位终端会发送定位消息，例如，定位终端通过持续广播的形式发送定位消息，该定位消息中携带定位终端的标识，相邻终端通过短距网络接收定位终端发送的定位消息，相邻终端收到定位消息后，相邻终端根据定位消息生成扫描报告消息，扫描报告消息携带定位消息的RSSI值、相邻终端的位置信息和可信度验证信息，定位终端将该扫描报告消息发送至定位服务器，定位服务器根据扫描报告消息获取定位消息的RSSI值、相邻终端的位置信息和可信度验证信息，定位服务器根据定位消息的RSSI值、相邻终端的位置信息和可信度验证信息确定定位终端的位置信息，并将该位置信息发送至定位终端。
换句话说，定位服务器并没有广播下发定位扫描请求消息，相邻终端只要扫描到定位消息，定位终端就会将该扫描报告消息发送至定位服务器。本实施中，只有开启短距网络的相邻终端才能够收到定位消息，换句话说，可能需要参与众包定位的用户长期开启短距通信模块，或者说，只有打开无线短距通信模块的用户才可以参与众包定位，对于用户来讲，可能比较费电，如果用户为了省电，自己关闭短距通信方式，对于定位服务提供者而言，可能导致参与众包的用户减少，本实施例中，是由用户手动控制开启或关闭短 距无线通信，本实施例给用户的感受可能会比较友好，提升用户体验，同样能够提高定位精确度。
可替代地，作为另一实施例，本发明实施例方法在320之前，还可以包括：

具体地，定位终端接收定位服务器发送的位置信息后，可以根据该位置信息是否准确进行反馈，产生反馈信息，并向定位服务器发送，定位服务器收到反馈信息后，根据反馈信息调整相邻终端的位置信息的可信度。例如，当反馈信息表示定位终端的位置信息较准确时，服务器可以根据反馈信息调高相邻终端的位置信息的可信度，当反馈信息表示定位终端的位置信息不准确时，服务器可以根据反馈信息调低相邻终端的位置信息的可信度。
上文中结合图2从定位服务器的角度描述了本发明实施例的定位的方法，结合图3从定位终端的角度描述本发明实施例的定位的方法。下面将结合图4从定位终端的相邻终端的角度描述本发明实施例的定位的方法。

上位中结合图2从定位服务器的角度描述了本发明实施例的定位的方法；结合图3从定位终端的角度描述本发明实施例的定位的方法；结合图4从定位终端的相邻终端的角度描述本发明实施例的定位的方法。下面将结合图5至图8的具体例子对本发明实施例的定位的方法做详细的描述。
图5是根据本发明另一实施例的定位方法的示意流程图。如图5所示，该方法包括：
501，定位终端向定位服务器发送定位请求消息。
具体地，要获取自己位置信息的定位终端向定位服务器发送定位请求消息，该定位请求消息用于向定位服务器请求自己的位置信息，在该定位请求消息中，携带定位终端的标识信息，例如，定位终端的身份标识(简称ID，英文IDentidy)、MAC(英文Media Access Control，介质访问控制))地址等。另外，在某些场景下，可能定位终端具有不是很精确的位置信息，比如通过GPS的或者基站定位出来的位置，定位请求消息中还可以携带该较粗略的位置信息。
502，定位服务器向相邻终端发送定位扫描请求消息。
具体地，定位服务器收到上述定位请求消息后，向参与了众包的成员广播定位扫描任务。具体地，定位服务器可以以广播的形式向所有成员发送该定位请求消息，也可以向部分成员发送该定位请求消息。更进一步的，如果定位请求消息中包含有定位终端的较粗略的位置信息，定位服务器可以根据该粗略的位置确定需要下发定位扫描任务的群组成员列表。例如，可以向该粗略位置周边的终端发送定位扫描请求消息。
503，相邻终端接收定位终端发送的定位消息。
具体地，收到定位服务器下发的定位扫描任务请求的终端(相邻终端)，会打开本地的短距无线通信模块，扫描接收由发起定位请求的定位终端在发起请求后用相同的短距无线通信方式开始持续广播的定位消息，该定位消息携带定位终端的用户标识。
504，相邻终端向定位服务器发送扫描报告消息。
其中，扫描报告消息携带定位消息的RSSI值、相邻终端的位置信息和可信度验证信息，
具体地，收到上述定位消息的相邻终端，会提取定位消息中的定位终端的用户标识，以及收到的定位消息信号的RSSI等信息，提取出的信息，会联合相邻终端自己本机的位置信息，生成扫描报告消息，扫描报告消息携带定位消息的RSSI值、相邻终端的位置信息和可信度验证信息。其中，该相邻终端的位置信息可以是用户主动输入，也可以是相邻终端自动获取本终端中可以获取的位置信息，例如，可以通过相邻终端的GPS模块，或者A-GPS模块获取相邻终端的位置信息，如果是用户主动输入位置信息，相邻终端在收到定位消息，可以通过UI界面显示输入窗口，提示用户输入当前的地理位置信息。可信度验证信息能够提供一个供定位服务器验证其可信度的验证证据信息。该可信度验证信息可以是用户输入或者用户选择的，也可以是通过相邻终端自动收集相关位置证据获得的。当可信度验证信息是用户输入或者用户选择的时候，相邻终端可以将其收集的能够用于证明其有效位置的数据呈现给用户，获取用户的选择，或者直接获取用户自己的手动输入的可信度验证信息。例如，当用户正在深圳坂田万科城丹桂轩吃自助，那么以下几种都可以作为可信度验证信息，第一种，GPS或A-GPS模块定位出来的用户大概位置；第二种，大众点评或美团等上面的消费记录等；第三种，用户主动拍摄的具有明显地理位置信息的实时图像或视频。应理解，可信息度验证信息包括至少上述一种情况。
应注意，上述相邻终端在收到定位服务器发送的定位扫描请求消息后，可以自动启动扫描定时器，该可以预设定时器的时间为5s、10s等，扫描定时器时间到期后，相邻终端可以自动关闭短距无线通信扫描功能，以避免由于参与众包定位而导致移动终端电量消耗过快。
505，定位服务器根据相邻终端的位置信息和可信度验证信息确定定位 终端的位置信息。
换句话说，定位服务器获取定位终端的相邻终端的位置信息和可信度验证信息。定位服务器根据可信度验证信息确定相邻终端的位置信息的可信度，可信度表示相邻终端的位置信息的精确程度。定位服务器根据相邻终端的位置信息和可信度确定定位终端的位置信息。
具体地，定位服务器在扫描定时器到期前，持续接收(收集)各个参与众包定位的相邻终端上报的扫描报告信息，并根据扫描报告信息中的可信度验证信息，对相邻终端的位置信息确定一个可信度，该可信度信息，可以理解为一个用于众包定位时其可以提供的精确度信息，例如，如表1所示，如果相邻终端上报的可信度验证信息是一个室内封闭环境的明显的商家标志(图片或视频)，并且还有其他的可信度证据信息，比如消费记录、通过GPS证明其所在的大概位置，并且在可信度验证的数据库中大概位置范围内，只有这样一个商家标志(图片或视频)，那么该用户提供的众包位置数据的可信度就很高，可以认为其能够提供的定位精度响应的也比较高，可以赋给其上报的位置以较高的可信度值，例如，其可信度指数为100。在例如，如果相邻终端提供的可信度验证信息仅有一张商家的店内的图片，则该相邻终端的位置可信度就会相对较低，例如，其可信度指数为1。换句话说，定位服务器可以根据相邻终端提供的位置可信度证据的多少确定可信度的大小。例如，可以设置可信度指数为1-100，数值越大表示位置信息的可信度越高，表示位置信息越精确。当然，为了定位算法的使用，也可以采用其他方式来表示可信度的高低，比如采用指数映射方式。可信度指数抽象出来以后，可以作为定位算法的系数或者指数来修正定位的精度。
表1可信度对应表
Figure PCTCN2015091511-appb-000001
应理解，上述给出了一个根据可信度验证证据映射出一个上报位置的可信度值的一个举例，上述例子只是一种可能的实现方式，还可以采用其他的方法确定位置信息的可信度，本发明实施并不对此做限定。
应理解，定位服务器确定出相邻终端的位置信息可信度以后，可以根据定位消息的RSSI值、相邻终端的位置信息和可信度确定定位终端的位置信息。其中，定位服务器在确定定位终端的位置时，可以将可信度高和RSSI值高的位置信息设置高的权重，将可信度低和RSSI值高的位置信息设置低的权重确定定位终端的位置信息，例如，可以采用三角定位法或质心定位法等来确定定位终端的位置信息。
换句话说，定位服务器参考对于多个上报的扫描信息，定位服务器经过验证其位置的可信度后，选择全部或者部分可信度较高的扫描报告，采用定位算法计算出被定为定位终端的位置信息，并将该信息下发给定位终端。
另外，定位服务器可以根据每次参与移动终端每次上报的位置可信度的情况，调整众包用户(已经在其定位系统注册的用户)的等级，也就是说，如果用户每次都贡献有效的位置，那么该用户就可以快速的成定位系统的优质用户，在以后的定位算法中，可以给予该用户(终端)的位置信息较高的权重。
506，定位服务器向定位终端发送定位终端的位置信息。
具体地，定位服务器可以通过蜂窝网络向定位终端发送定位终端的位置信息。
507，定位终端向定位服务器发送反馈信息。
具体地，反馈信息表示定位终端的位置信息是否准确；
定位终端向定位服务器发送反馈信息，以便定位服务器根据反馈信息调整相邻终端的位置信息的可信度。
508，定位服务器根据反馈信息调整相邻终端的位置信息的可信度。
具体地，例如，定位终端接收定位服务器发送的位置信息后，可以根据该位置信息是否准确进行反馈，产生反馈信息，并向定位服务器发送，定位服务器收到反馈信息后，根据反馈信息调整相邻终端的位置信息的可信度。例如，当反馈信息表示定位终端的位置信息较准确时，服务器可以根据反馈信息调高相邻终端的位置信息的可信度，当反馈信息表示定位终端的位置信息不准确时，服务器可以根据反馈信息调低相邻终端的位置信息的可信度。
另外，定位服务器可以对于用户上报的位置进行管理，比如，根据用户的移动速度、消费记录等等，对于相邻终端上报的位置赋上一个有效时间。对于有效时间内的用户，可能再次需要通过该终端进行众包定位时，就不再需要其上报位置信息，直接使用众包定位数据库中存储的有效位置数据就可以，例如，当用户(相邻终端)的移动速度较低或者用户位置固定时，有效时间可以较长，例如，1分钟、5分钟或10分钟等，当用户的移动速度较高时，有效时间可以较低，例如为10s钟，具体地，可以根据实际需要而定，本发明实施例并不对此作限定。
图6是根据本发明另一实施例的定位方法的示意流程图。如6实施例相对于图5实施例的区别点在于，定位服务器不会向相邻终端发送定位扫描请求消息，相邻终端只要扫描到定位终端发送的定位消息后信息就上报扫描报告消息，具体地，如图6所示，该方法包括：
601，定位终端向定位服务器发送定位请求消息。
具体地，要获取自己位置信息的定位终端向定位服务器发送定位请求消息，该定位请求消息用于向定位服务器请求自己的位置信息，在该定位请求消息中，携带定位终端的标识信息，例如，定位终端的ID、MAC地址等。另外，在某些场景下，可能定位终端具有不是很精确的位置信息，比如通过GPS的或者基站定位出来的位置，定位请求消息中还可以携带该较粗略的位置信息。
602，定位终端发送定位消息。
具体地，定位终端在发起请求后，采用短距无线通信方式开始持续广播的定位消息，该定位消息携带定位终端的用户标识。
603，相邻终端向定位服务器发送扫描报告消息。
其中，扫描报告消息携带定位消息的RSSI值、相邻终端的位置信息和可信度验证信息，
具体地，开启短距无线通信方式的相邻终端接收定位终端发送的定位消息，相邻终端收到定位消息后，会提取定位消息中的定位终端的用户标识，以及收到的定位消息信号的RSSI等信息，提取出的信息，会联合相邻终端自己本机的位置信息，生成扫描报告消息，扫描报告消息携带定位消息的RSSI值、相邻终端的位置信息和可信度验证信息。其中，该相邻终端的位置信息可以是用户主动输入，也可以是相邻终端自动获取本终端中可以获取 的位置信息，例如，可以通过相邻终端的GPS模块，或者A-GPS模块获取相邻终端的位置信息，如果是用户主动输入位置信息，相邻终端在收到定位消息，可以通过UI界面显示输入窗口，提示用户输入当前的地理位置信息。可信度验证信息能够提供一个供定位服务器验证其可信度的验证证据信息。该可信度验证信息可以是用户输入或者用户选择的，也可以是通过相邻终端自动收集相关位置证据获得的。当可信度验证信息是用户输入或者用户选择的时候，相邻终端可以将其收集的能够用于证明其有效位置的数据呈现给用户，获取用户的选择，或者直接获取用户自己的手动输入的可信度验证信息。例如，当用户正在深圳坂田万科城丹桂轩吃自助，那么以下几种都可以作为可信度验证信息，第一种，GPS或A-GPS模块定位出来的用户大概位置；第二种，大众点评或美团等上面的消费记录等；第三种，用户主动拍摄的具有明显地理位置信息的实时图像或视频。应理解，可信息度验证信息包括至少上述一种情况。
应注意，上述相邻终端在收到定位服务器发送的定位扫描请求消息后，可以自动启动扫描定时器，该可以预设定时器的时间为5s、10s等，扫描定时器时间到期后，相邻终端可以自动关闭短距无线通信扫描功能，以避免由于参与众包定位而导致移动终端电量消耗过快。
604，定位服务器根据相邻终端的位置信息和可信度验证信息确定定位终端的位置信息。
换句话说，定位服务器获取定位终端的相邻终端的位置信息和可信度验证信息。定位服务器根据可信度验证信息确定相邻终端的位置信息的可信度，可信度表示相邻终端的位置信息的精确程度。定位服务器根据相邻终端的位置信息和可信度确定定位终端的位置信息。
具体地，定位服务器在扫描定时器到期前，持续接收(收集)各个参与众包定位的相邻终端上报的扫描报告信息，并根据扫描报告信息中的可信度验证信息，对相邻终端的位置信息确定一个可信度，该可信度信息，可以理解为一个用于众包定位时其可以提供的精确度信息，例如，如表1所示，如果相邻终端上报的可信度验证信息是一个室内封闭环境的明显的商家标志(图片或视频)，并且还有其他的可信度证据信息，比如消费记录、通过GPS证明其所在的大概位置，并且在可信度验证的数据库中大概位置范围内，只有这样一个商家标志(图片或视频)，那么该用户提供的众包位置数据的可 信度就很高，可以认为其能够提供的定位精度响应的也比较高，可以赋给其上报的位置以较高的可信度值，例如，其可信度指数为100。在例如，如果相邻终端提供的可信度验证信息仅有一张商家的店内的图片，则该相邻终端的位置可信度就会相对较低，例如，其可信度指数为1。换句话说，定位服务器可以根据相邻终端提供的位置可信度证据的多少确定可信度的大小。例如，可以设置可信度指数为1-100，数值越大表示位置信息的可信度越高，表示位置信息越精确。当然，为了定位算法的使用，也可以采用其他方式来表示可信度的高低，比如采用指数映射方式。可信度指数抽象出来以后，可以作为定位算法的系数或者指数来修正定位的精度。
应理解，上述给出了一个根据可信度验证证据映射出一个上报位置的可信度值的一个举例，上述例子只是一种可能的实现方式，还可以采用其他的方法确定位置信息的可信度，本发明实施并不对此做限定。
应理解，定位服务器确定出相邻终端的位置信息可信度以后，可以根据定位消息的RSSI值、相邻终端的位置信息和可信度确定定位终端的位置信息。其中，定位服务器在确定定位终端的位置时，可以将可信度高和RSSI值高的位置信息设置高的权重，将可信度低和RSSI值高的位置信息设置低的权重确定定位终端的位置信息，例如，可以采用三角定位法或质心定位法等来确定定位终端的位置信息。
换句话说，定位服务器参考对于多个上报的扫描信息，定位服务器经过验证其位置的可信度后，选择全部或者部分可信度较高的扫描报告，采用定位算法计算出被定为定位终端的位置信息，并将该信息下发给定位终端。
另外，定位服务器可以根据每次参与移动终端每次上报的位置可信度的情况，调整众包用户(已经在其定位系统注册的用户)的等级，也就是说，如果用户每次都贡献有效的位置，那么该用户就可以快速的成定位系统的优质用户，在以后的定位算法中，可以给予该用户(终端)的位置信息较高的权重。
605，定位服务器向定位终端发送定位终端的位置信息。
具体地，定位服务器可以通过蜂窝网络向定位终端发送定位终端的位置信息。
606，定位终端向定位服务器发送反馈信息。

定位终端向定位服务器发送反馈信息，以便定位服务器根据反馈信息调整相邻终端的位置信息的可信度。
607，定位服务器根据反馈信息调整相邻终端的位置信息的可信度。
具体地，例如，定位终端接收定位服务器发送的位置信息后，可以根据该位置信息是否准确进行反馈，产生反馈信息，并向定位服务器发送，定位服务器收到反馈信息后，根据反馈信息调整相邻终端的位置信息的可信度。例如，当反馈信息表示定位终端的位置信息较准确时，服务器可以根据反馈信息调高相邻终端的位置信息的可信度，当反馈信息表示定位终端的位置信息不准确时，服务器可以根据反馈信息调低相邻终端的位置信息的可信度。
另外，定位服务器可以对于用户上报的位置进行管理，比如，根据用户的移动速度、消费记录等等，对于终端上报的位置赋上一个有效时间。对于有效时间内的用户，可能再次需要通过该终端进行众包定位时，就不再需要其上报位置信息，直接使用众包定位数据库中存储的有效位置数据就可以，例如，当用户(相邻终端)的移动速度较低或者用户位置固定时，有效时间可以较长，例如，1分钟、5分钟或10分钟等，当用户的移动速度较高时，有效时间可以较低，例如为10s钟，具体地，可以根据实际需要而定，本发明实施例并不对此作限定。
在本发明实施例中，只有打开无线短距通信模块的用户才可以参与众包定位，对于用户来讲，可能比较费电，如果用户为了省电，自己关闭短距通信方式，对于定位服务提供者而言，可能导致参与众包的用户较少。由于是由用户自己来控制开关自己手机上的无线短距通信模块的，该实施例方法给用户的感受可能会比较友好。
图7是根据本发明另一实施例的定位方法的示意流程图。如7实施例相对于图5实施例的区别点在于，服务器广播或组播下发定位扫描请求后，由收到该请求的参与众包定位的移动终端(相邻终端)发送广播信息，广播消息携带相邻终端的位置信息、相邻终端的可信度验证信息。参与众包定位的相邻终端可以持续一段时间广播该广播消息，例如，可以通过定时器来确定该一端时间。收到广播消息定的定位终端会根据收集上来的广播消息，以及每个消息的RSSI值，生成上报消息，上报消息携带相邻终端的位置信息、相邻终端的可信度验证信息和广播消息的RSSI值，进一步地，生成定位请求消息，定位请求消息包括上报消息。

702，定位服务器会向相邻终端发送定位扫描请求消息。
具体地，定位服务器收到上述定位请求消息后，向参与了众包的成员广播定位扫描任务。具体地，定位服务器可以以广播的形式向所有成员发送该定位请求消息，也可以向部分成员发送该定位请求消息。更进一步的，如果定位请求消息中包含有定位终端的较粗略的位置信息，定位服务器可以根据该粗略的位置确定需要下发定位扫描任务的群组成员列表。例如，可以向该粗略位置周边的终端发送定位扫描请求消息。
应注意，上述相邻终端在收到定位服务器发送的定位扫描请求消息后，可以自动启动扫描定时器，该可以预设定时器的时间为5s、10s等，扫描定时器时间到期后，相邻终端可以自动关闭短距无线通信扫描功能，以避免由于参与众包定位而导致移动终端电量消耗过快。
