Description

实现地理围栏的方法和移动设备 技术领域
本发明涉及移动通信领域，尤其涉及一种实现地理围栏的方法和移动设备。
背景技术
地理围栏(Geo-fencing)是一种监测移动设备与特定地理区域之间的关系，并根据该关系提供信息服务的技术。其中，该特定地理区域由地理栅栏(geo-fence)确定。地理围栏的实现流程通常如下：首先建立地理栅栏；然后启动实时定位；接着比较地理栅栏的坐标与定位结果的坐标，判断移动设备是处于地理栅栏内还是外；最后，根据判断结果执行相应操作，如发送提醒、警告消息、在地图上显示定位点等。
通常地理栅栏的坐标和定位结果的坐标均采用相同的坐标系。然而，实际应用中，地理栅栏的坐标系与定位结果的坐标系常常会出现不一致的情况，从而导致较大的偏差。例如，当用户直接从采用GCJ02、BD09或BD09LL坐标系的地图上取点建立地理栅栏，并以全球定位系统(英文：Global Positioning System，缩写：GPS)作为定位技术时，地理栅栏的坐标系与利用GPS得到的定位结果所用的坐标系WGS84不同。
对于上述问题，现有技术中提供了另一种实现地理围栏的方法：直接规定了地理栅栏及定位结果分别可采用的坐标系，且在内部实现各坐标系间的转换；在每次成功定位时将定位结果的坐标转换成地理栅栏所采用的坐标系下的坐标，然后将该定位结果转换后的坐标与地理栅栏的坐标进行比较。然而，在这种方法中，在每一次启动地理围栏之后每隔一段时间会得到一个定位结果(例如，每二十秒得到一个定位结果)，由于每一个定位结果都要进行坐标转换，而后与地理栅栏的坐标进行比较，整个运算过程繁复，导致实现地理围栏的功耗较大。

具体实施方式
本发明实施例提供了一种实现地理围栏的方法和移动设备，用于降低实现地理围栏的功耗。
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“包含”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包含没有清楚地列出的或对于这些过程、方法、系统、产品或设备固有的其它步骤或单元。
需要说明的是：本文中所涉及的地理围栏(Geo-fencing)在设备中可以以一个应用或功能的形式体现，地理栅栏(geo-fence)是用户在设备的屏幕上设 定的一个栅栏。
请参阅图1，本发明的一个实施例中实现地理围栏的方法包含：
101、在检测到地理栅栏被设定时，确定在第一坐标系下表示所述地理栅栏的第一坐标，所述第一坐标系为所述地理栅栏采用的坐标系。
对地理栅栏采用不同的设定方法时，由于不同的设定方法中采用的坐标系可能不同，因此地理栅栏在不同的设定方法中的坐标也可能不同。当检测到地理栅栏被设定时，确定该地理栅栏的坐标以及该坐标是哪个坐标系下的。为描述方便，称该坐标为第一坐标，该坐标系为第一坐标系。
需要说明的是：“地理栅栏被设定”可以理解为：用户在设备的屏幕上手指滑动得到的地理栅栏，或者用户选择设备保存的地理栅栏，或者，用户在设备的屏幕上输入圆心和半径，利用其它应用加载得到地理栅栏。“在第一坐标系下表示所述地理栅栏的第一坐标”可以理解为：在第一坐标系下第一坐标可以表示地理栅栏，其中，第一坐标可以是多个坐标的集合或者一个坐标。
应理解：不同的地理栅栏采用的坐标系可以相同也可以不同，在此不作限制。
102、将所述第一坐标转换为在第二坐标系下表示所述地理栅栏的第二坐标，所述第二坐标系为实现所述地理围栏设定的定位技术采用的坐标系，所述第一坐标系与所述第二坐标系不同。
在实现地理围栏时，移动设备根据设定的定位技术获得定位结果，并将获得的定位结果与地理栅栏所圈出的地理区域进行比较，以确定地理栅栏与该定位结果之间的关系。移动设备在进行比较时是将地理栅栏的坐标和定位结果的坐标进行比较。然而，地理栅栏采用的坐标系(也即第一坐标系)和为实现地理围栏所设定的定位技术采用的坐标系(也即第二坐标系)并不一定是同一个坐标系。因此，在第一坐标系和第二坐标系不同时，将第一坐标转换为第二坐标系下表示该地理栅栏的第二坐标。应理解：“在第二坐标系下表示所述地理栅栏的第二坐标”可以理解为：在第二坐标系下第二坐标可以表示地理栅栏，其中，第二坐标可以是多个坐标的集合或者一个坐标。
实际运用中，在将第一坐标转换为第二坐标之前，可以首先判断一下第一坐标系和第二坐标系是否相同，如果相同，则不需要对第一坐标进行转换；如 果不同，则将第一坐标转换为第二坐标。或者，也可以不判断第一坐标系和第二坐标系是否相同，而是直接将第一坐标转换为第二坐标；若第一坐标系和第二坐标系相同，那么转换后得到的第二坐标和第一坐标相同，若第一坐标系和第二坐标系不同，那么转换后得到的第二坐标和第一坐标不同。
将第一坐标转换为第二坐标的方法有多种。举例来说，可预置第一坐标系可能采用的坐标系转换到第二坐标系可能采用的坐标系所需的转换模型，在将第一坐标转换为第二坐标时，从各转换模型中挑选出适合当前采用的转换模型，并根据该转换模型来进行转换。
应理解：在检测到至少两个地理栅栏被设定的情况下，对每一个地理栅栏的第一坐标进行转换。
103、将利用所述定位技术确定的定位结果的坐标与表示所述地理栅栏的所述第二坐标进行比较。
定位技术有多种，例如全球导航卫星系统(英文：Global Navigation Satellite，缩写：GNSS)、蜂窝定位、无线保真定位(英文：Wireless-Fidelity，缩写：Wi-Fi)、传感器定位、蓝牙定位等等中的任意一种或多种。其中，GNSS可以是全球定位系统(英文：Global Positioning System，缩写：GPS)、北斗卫星导航系统(英文：BeiDou Navigation Satellite System，缩写：BDS)、伽利略定位系统等中的至少一个。不同的定位技术采用的坐标系可能相同，也可能不同。
在实现地理围栏的过程中，选择好定位技术后启动该定位技术对应的定位功能。具体的，启动该定位功能的时间可以在将第一坐标转换为第二坐标之前，也可以在将第一坐标转换为第二坐标之后，在此不作限制。
实际运用中，可预先设置好每种定位技术进行定位的频率，例如每分钟内定位60次，或者每分钟内定位30次等等，其中不同定位技术进行定位的频率可以相同也可以不同，在此不作限制。每获得一个定位结果，将该定位结果的坐标与地理栅栏的第二坐标进行比较。
应理解：在检测到至少两个地理栅栏被设定的情况下，将每一个地理栅栏的第二坐标和定位结果的坐标进行比较。
104、当所述定位结果的坐标与表示所述地理栅栏的所述第二坐标之间的 关系满足触发条件时，触发预设事件。
举例来说，该触发条件可以是定位结果位于地理栅栏内或者定位结果位于地理栅栏附近预置区域内。当满足该触发条件时，预设事件可以是推送该预置区域的相关广告信息，或者是自动登录该预置区域的社交网络，或者是显示实时位置等等。或者，该触发条件可以是定位结果位于地理栅栏之外。当满足该触发条件时，预设事件可以是自动退出预置区域的社交网络等等。
当然，上述对触发条件和预设事件的描述仅为举例说明，并不作限制。优选的，可以预设有供选择的多种触发条件和触发事件，在用户设置完成后，移动设备根据选择设置好的触发条件执行选择设置好的预设事件。
在检测到至少两个地理栅栏被设定的情况下，不同的地理栅栏对应的预设事件可以相同也可以不同，定位结果与不同的地理栅栏之间要满足的触发条件可以相同也可以不同。还可以预先设置不同地理栅栏对应的预设事件的优先级，在出现定位结果和至少两个地理栅栏之间同时满足对应的触发条件时，根据该优先级来执行预设事件。
本实施例中，由于在得到利用定位技术确定的定位结果之前，先将地理栅栏在该地理栅栏采用的第一坐标系下的第一坐标转换为该定位技术采用的第二坐标系下表示该地理栅栏的第二坐标，这样，在后续将每一个定位结果与地理栅栏进行比较时，无需将定位结果转换为地理栅栏所采用的坐标系下的定位结果，整个过程只进行了一次坐标转换，相比背景技术中每个定位结果都要进行一次坐标转换，本发明能够大大降低地理围栏的运算复杂程度，进而降低了地理围栏的功耗，而且能够消除因地理栅栏和定位结果的坐标系不同而导致的位置偏移问题。
本实施例中，在执行步骤101至104时，可以由移动设备(例如手机、平板电脑)或者应用程序处理器(英文：Application Processor，缩写：AP)来执行。优选的，还可以由独立于AP的低功耗处理器或者独立于AP的低功耗片上系统(英文：System on Chip，缩写：SoC)执行，其中该低功耗处理器和低功耗SoC分别指的是功耗小于AP功耗的处理器和SoC。这样，可以降低地理围栏时所需的功耗。
本实施例中，移动设备需利用一种定位技术进行定位。实际运用中，也可 以不仅仅是利用一种定位技术进行定位，还可以是利用至少两种定位技术，并在进行定位时在至少两种定位技术中进行切换。优选的，可以预先设置地理围栏采用的一个或多个定位技术。
在采用在至少两种定位技术中进行切换的定位模式时：在步骤102中，对每一个地理栅栏，需将该地理栅栏的第一坐标转换分别转为不同的定位技术采用的坐标系下表示该地理栅栏的新坐标。在步骤103中，将地理栅栏与每一个定位结果进行比较时，首先确定地理栅栏对应该定位结果的坐标系下的新坐标，再采用确定后的新坐标与定位结果的坐标进行比较。
本实施例中，需将所述第一坐标转换为在第二坐标系下表示所述地理栅栏的第二坐标。优选的，采用迭代偏移估计算法将所述第一坐标转换为在第二坐标系下表示所述地理栅栏的第二坐标。下面对迭代偏移估计算法进行解释。
为方便对迭代偏移估计算法进行描述，首先说明：移动设备内存储有移动设备内任意一个定位技术所采用的坐标系B转换为地理栅栏所采用的坐标系A的变换模型(简称为B-A变换模型)。请参阅图2，图2为本发明的实现地理围栏的方法中采用迭代偏移估计算法的示意图。
假设目标位置的第一坐标是一维空间下的一个坐标，已知该目标位置在一维坐标系A(也即第一坐标系)内的坐标为x1(也即第一坐标)，求解该x1对应到一维坐标系B(也即第二坐标系)中的坐标值x(也即第二坐标)。下面对迭代偏移估计算法进行具体描述。
步骤a，估计第一坐标x1和第二坐标x之间的偏移值。对坐标变换，存在以下两点合理假设：1、坐标系B内任意相邻的两个点(称为点1和点2)，该两个点分别映射到坐标系A内后得到两个映射点(称为点1'和点2')，点1'和点1之间的偏移与点2'和点2之间的偏移相近似。2、一个点在坐标系A内的坐标值a和在坐标系B内的坐标值b的距离相近。
如图2所示，坐标系B内点m的坐标值为x，映射到坐标系A的点m'的坐标值为x1；坐标系B内点n的坐标值为x1，映射到坐标系A的点n'坐标值为x2，其中x2为x1根据B-A变换模型计算出的该坐标系B中的x1映射到坐标系A中得到的坐标值。
根据上述第2点合理假设有：x和x1的距离相近，因此在坐标系B内点 m和点n相邻。进而根据上述第1点合理假设有：点m'和点m之间的偏移d与点n'和点n之间的偏移d1近似，其中d＝x1－x，d1＝x2－x1；也即，d≈d1。
步骤b，计算x的估计值x'。由于d≈d1，因此，x1－x≈x2－x1，那么x≈x1－(x2－x1)，即有x'＝x1－(x2－x1)。
步骤c，进行迭代运算。如图2所示，由于x'相比x1是更加接近真实的x的，因此在坐标系B中将点n的坐标值替换为x'，根据B-A变换模型计算出坐标系B中坐标值为x'的点在坐标系A中的映射点的坐标值为x2'，也即将坐标系A中点n'的坐标值替换为x2'；那么新偏移值d1＝x2'－x'相比旧d1＝x2－x1是更加接近偏移值d的。因此x2'－x'≈x1－x，那么x≈x1－(x2'－x')，即有x的新估计值x″＝x1－(x2'－x')。
同上，x″相比x'是更加接近真实的x的，因此将点n的坐标值替换为x″。一直重复步骤c，直至点n替换后的坐标值映射到坐标系A中的坐标值与x1的差值的绝对值小于预置数值时，也即坐标系A内最新得到的点n'与点m'的距离小于预置数值时，即可得到接近于真实x的估计值。该预置数值由移动设备根据需求来设定，例如根据时延、计算复杂度等需求来设定。
对于二维坐标和三维坐标，每个维度的转换原理与一维坐标的转换相同，可根据上述步骤扩展得到，详细过程此处不再赘述。
同样的，在地理栅栏的第一坐标是多个坐标的集合的情况下，对第一坐标中的每一个坐标均采用上述迭代偏移估计方法，即可计算出该每一个坐标转换到第二坐标系下的坐标，那么计算出来的第二坐标系下的各坐标的集合则是第二坐标系下表示该地理栅栏的第二坐标。
本实施例中，采用迭代偏移估计算法来将地理栅栏的第一坐标转换为第二坐标，可以满足转换各种不同坐标系的需求，可应用于采用了各种不同坐标系的地理围栏中，适用范围更广。
为便于理解，下面以一个实际应用场景对本发明实施例的实现地理围栏的方法进行描述。
本实施例中，移动设备为手机。在设定地理栅栏时，手机的触摸显示屏上显示地图，其中该地图采用的坐标系为BD09。用户通过在触摸屏上滑动在该地图上手动圈出一个地理区域，手机获取该地理区域的边缘各点的坐标值，并 将各点的坐标值设定为地理栅栏，因此地理栅栏采用的坐标系为BD09。手机在检测到地理栅栏被设定时，确定坐标系BD09下表示该地理栅栏的第一坐标。
手机内预设实现地理围栏设定的定位技术采用的坐标系为格洛纳斯系统(英文缩写GLONASS)，该GLONASS采用的坐标系为PE-90。手机内预存有将坐标系PE-90转换到坐标系BD09所需的转换模型。
手机采用迭代偏移估计算法将第一坐标中的每一个坐标值转换成PE-90坐标系下表示该地理栅栏的第二坐标。
在计算第二坐标后，手机根据所设定的定位技术开启GLONASS定位功能，以对手机进行定位。手机内预先设置有定位频率，在开启定位功能后每隔一段时间获取定位结果的坐标，并将该定位结果的坐标与第二坐标进行比较。
当确定定位结果的坐标位于地理栅栏之外且距离地理栅栏的最短距离小于等于5米时，手机发出即将进入某区域的提醒消息。当确定实时定位结果位于地理栅栏内时，自动登录某区域的社交网络，并推送某区域的相关广告信息。当确定实时定位结果位于地理栅栏之外且距离地理栅栏距离大于5米时，自动退出某区域的社交网络。
