Description
本发明实施例涉及定位技术,尤其涉及一种移动终端的控制方法、装置及系统。
不同环境下的定位通常需要使用不同的定位技术。如,GNSS(Global Navigation Satellite System,全球导航卫星系统)定位技术通常用于支持室外环境下的定位;Wi-Fi、蓝牙定位技术等通常用于支持室内环境下的定位。
现有定位方式的选择通常根据移动终端接收到的信号情况决定。这里的信号既可以是GNSS卫星信号,也可以是蜂窝基站信号、Wi-Fi信号等。然而,由于现有导航定位方式选择时,依赖的信号易受NLOS(Non-line-of-Sight,非视距)传输、环境因素等的影响,常常会引入较大的误差,以致错误的判断移动终端的位置,而选择不合适的定位方式。以GNSS为例,GNSS卫星信号极易受高楼、树木等的遮挡,因此在城市峡谷区域(如两侧是高楼的街道)也会出现GNSS可视卫星数量较少、信号强度较低的情况,此时极易误判移动终端进入了室内环境,而错误的切换为室内定位方式或加载室内导航地图。

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,都属于本发明保护的范围。
当本发明实施例提及“第一”、“第二”等序数词时,除非根据上下文其确实表达顺序之意,应当理解为仅仅起区分的作用。
图1为本发明实施例的一种移动终端的控制方法的流程图,如图1所示,该方法包括:
步骤101、接收多天线节点在N个时刻分别发送的N个测向信号,所述多天线节点位于室内外临界区域。
室内室外的界面,通常是以墙壁、门或窗等界定的。墙壁、门或窗以内为室内,墙壁、门或窗以外为室外,而墙壁、门或窗等可以称为是室内外交界面。室内外临界区域是在室内外交界面附近且包含室内外交界面在内的一个空间区域。图2为本发明实施例的一种室内外临界区的示意图,如图2所示:第一平面平行于室内外交界面且与室内外交界面相距第一预设距离,第二平面平行于室内外交界面且与室内外交界面相距第二预设距离,第一平面与第二平面之间的空间均属于室内外临界区域;其中第一预设距离或第二预设距离可以根据需要预先设置,例如可以为5米、8米或10米等,第一预设距离与第二预设距离可以相等,也可以不等。
图3为本发明实施例的一种应用场景示意图。如图3所示,室内外交界面为商场的大门,在大门外和大门内、距离大门一定距离的空间范围可以称为室内外临界区域,其中室内外临界区域的大小可以根据实际情况设定。例如门外的立柱、大门、门内的柜子均位于室内外临界区域之内。本发明实施例的多天线节点位于室内外临界区域,多天线节点可以设置于位于室内外临界区域内的任何建筑物上,如图3所示,多天线节点可以位于门外的立柱上、大门上方或者门内的柜子上。
图4为本发明实施例的移动终端与多天线节点之间收发信号的示意图。如图4所示,多天线节点在N个时刻t1、t2、……tN分别发送N个测向信号,该N个时刻例如可以是固定时间间隔的N个时刻,也可以是变化时间间隔的N个时刻;移动终端可以按照测向信号发送的顺序,接收多天线节点在N个时刻分别发送的N测向信号。
需要说明的是,多天线节点具有多个用于收发信号的天线,例如可以为多天线Wi-Fi节点或多天线蓝牙节点。多天线节点可以处于信号收发状态,当移动终端进入其信号的覆盖范围时,移动终端就可以接收多天线节点发出的测向信号。
步骤102,根据所述N个测向信号,获取在所述N个时刻时所述移动终端与所述多天线节点之间的N个位置关系信息,所述N个时刻与所述N个位置关系信息一一对应。
具体来说,移动终端与多天线节点之间的位置关系信息,例如为方位角和仰角θ。移动终端接收到多天线节点发出的测向信号后,例如可以通过2D MUSIC(2dimensional Multiple Signal Classification,多信号分类)算法、2D FBSS(2D forward/backward spatial smoothing-Music,2维前/后向空间平滑多信号分类)算法、2D FBSS-DOAM(2D FBSS based direction of arrival matrix,基于前/后向空间平滑的波达方向矩阵)算法或ESPRIT(2D Estimation of signal parameters by rotational invariance techniques,旋转不变技术估计信号参数)算法等来计算移动终端与多天线节点之间的方位角和仰角θ,移动终端与多天线节点之间的方位角和仰角θ的信息即为移动终端与多天线节点之间的位置关系信息。该算法可以由移动终端内植入代码通过软件来实现,还可以通过一个具有该计算功能的芯片来实现。
移动终端会根据多天线节点发送的N个测向信号,获取在N个时刻时,移动终端与多天线节点之间的N个方位角和N个仰角θ,也就是说,在N个时刻获取到和θ时,就获取到了在N个时刻所述移动终端与所述多天线节点之间的N个位置关系信息,且,所述N个时刻与所述N个位置关系信息一一对应,N≥2。
图5为本发明实施例的确定方位角和仰角坐标系的示意图,如图5所示,确定和θ的坐标系可以按照如下方式设定:地面为x-y平面,所述多天线节点在x-y平面的投影为原点,z轴垂直于x-y平面指向上方,y轴平行于室内外交界面,x轴垂直于y轴指向室外方向;为直线k1与x轴正
方向的夹角,直线k1为所述移动终端到地面的投影与所述原点之间的连线,移动终端到地面的距离为h;θ为直线k2与z轴负方向的夹角,直线k2为所述移动终端与所述多天线节点之间的连线。其中,x、y、z仅仅为了标注方便,其名称可以用其他字母来代替,只要不改变和θ的物理空间位置即可。
步骤103,根据所述N个位置关系信息中的至少M个位置关系信息,确定所述移动终端与所述多天线节点之间的位置关系的变化信息,2≤M≤N。
如果移动终端在运动中,如,从室内向室外移动,或从室外向室内移动,由于N个时刻与N个位置关系信息一一对应,那么在N个时刻获取的移动终端与多天线节点之间的位置关系是变化的。移动终端可以根据N个时刻获取的移动终端与多天线节点之间的位置关系信息获取移动终端与多天线节点之间的位置关系的变化信息。位置关系的变化信息表示移动终端相对于多天线节点的方位角和仰角的变化的信息,用于表示移动终端的运动趋势,即,移动终端从室外向室内运动,还是从室内向室外运动。
例如,当获取的N个时刻的N个位置关系信息为以及θ1、θ2、…、θN时,可以根据N个位置关系信息来确定移动终端与多天线节点之间的位置关系的变化信息,还可以选择N个位置关系信息中的M个位置关系信息来确定移动终端与多天线节点之间的位置关系的变化信息,M个位置关系信息可以是N个中连续选取的几个,也可以是间隔顺序选取的几个,其中,2≤M≤N。
步骤104、所述根据所述位置关系的变化信息,以与所述位置关系的变化信息相匹配的方式控制所述移动终端。
下面将结合附图5说明,移动终端如何根据位置关系的变化信息,选择与位置关系的变化信息相匹配的控制方式控制自身的操作。
例如,当时,如果移动终端与多天线节点之间的方位角逐渐增加,即位置关系的变化信息为时,则表明移动终
端的运动趋势为从室外向室内运动,那么以对应于这种运动趋势的第一方式控制所述移动终端;如果移动终端与多天线节点之间的方位角逐渐减小,即位置关系的变化信息为时,则表明移动终端的运动趋势为从室内向室外运动,那么以对应于这种运动趋势的第二方式控制所述移动终端,其中,为第i个时刻的方位角,1≤i≤M。
当时,如果移动终端与多天线节点之间的方位角逐渐减小,即位置关系的变化信息为则表明移动终端的运动趋势为从室外向室内运动,那么以对应于这种运动趋势的第一方式控制所述移动终端,如果移动终端与多天线节点之间的方位角逐渐增加,即位置关系的变化信息为则表明移动终端的运动趋势为从室内向室外运动,那么以对应于这种运动趋势的第二方式控制所述移动终端,其中,为第i个时刻的方位角,1≤i≤M。
当或时,如果移动终端与多天线节点之间的方位角不变,仰角逐渐减小,即位置关系的变化信息为
且θ1>θ2>…>θM>0,,则表明移动终端的运动趋势为从室外向室内运动,那么以对应于这种运动趋势的第一方式控制所述移动终端,如果移动终端与多天线节点之间的方位角不变,仰角逐渐增加,即位置关系的变化信息为且0<θ1<θ2<…<θM,则表明移动终端的运动趋势为从室内向室外运动,那么以对应于这种运动趋势的第二方式控制所述移动终端,其中,为第i个时刻的方位角,θi为第i个时刻的仰角,1≤i≤M。
当时,如果移动终端与多天线节点之间的方位角不变,仰角逐渐增加,即位置关系的变化信息为且0<θ1<θ2<…<θM,则表明移动终端的运动趋势为从室外向室内运动,那么以对应于这种运动趋势的第一方式控制所述移动终端,如果移动终端与多天线节点之间的方位角不变,仰角逐渐减小,即位置关系的变化信息为
且θ1>θ2>…>θM>0,则表明移动终端的运动趋势为从室内向室外运动,那么以对应于这种运动趋势的第二方式控制所述移动终端,其中,
为第i个时刻的方位角,θi为第i个时刻的仰角,1≤i≤M。
可选的,为了更加准确的判断移动终端的运动趋势,还可以基于以下四种条件中的任意一种,来根据位置关系的变化信息,选择与位置关系的变化信息相匹配的控制方式控制自身的操作。
第一种条件:当时,如果移动终端与多天线节点之间的方位角逐渐增加,仰角逐渐减小,即位置关系的变化信息为
且θ1>θ2>…>θM,则表明移动终端的运动趋势为从室外向室内运动,那么以对应于这种运动趋势的第一方式控制所述移动终端;如果移动终端与多天线节点之间的方位角逐渐减小,仰角逐渐增加,即位置关系的变化信息为且θ1<θ2<…<θM,则表明移动终端的运动趋势为从室内向室外运动,那么以对应于这种运动趋势的第二方式控制所述移动终端。
第二种条件:当时,如果移动终端与多天线节点之间的方位角逐渐增加,仰角逐渐增加,即位置关系的变化信息为

移动终端。
第四种条件:当时,如果移动终端与多天线节点之间的方位角逐渐增加,仰角逐渐增加,即位置关系的变化信息为
且θ1<θ2<…<θM,则表明移动终端的运动趋势为从室内向室外运动,那么以对应于这种运动趋势的第二方式控制所述移动终端;如果移动终端与多天线节点之间的方位角逐渐减小,仰角逐渐减小,即位置关系的变化信息为且θ1>θ2>…>θM,则表明移动终端的运动趋势为从室外向室内运动,那么以对应于这种运动趋势的第一方式控制所述移动终端。
需要说明的是,本发明实施例中获取N个时刻时移动终端与多天线节点之间的N个位置关系信息,但是启用控制移动终端的动作,可以选取不同时间点。例如,设定预设时长、设定获取位置关系的数量、设定具体位置关系信息。
具体如下:
例如,设定预设时长,即从获取移动终端与多天线节点之间的第一个位置关系信息开始,到预设时长时,根据在该预设时长内获取的位置关系信息,确定移动终端与多天线节点之间的位置关系的变化信息,进而执行对移动终端的控制动作。该预设时长,可以为1秒、2秒或5秒等,预设时长例如可以根据移动终端所处环境或多天线节点参数来设置。可以以将预设时长平均分配选取N个时刻,也可随机选取N个时刻,获取N个位置关系信息。在具体实现中,可以固定时间窗,在每个时间窗内,根据获取到的位置关系信息来控制移动终端的动作。
例如,预设获取位置关系的数量,即从获取移动终端与多天线节点之间的第一个位置关系信息开始,到达第一预设位置关系数量,例如N个时,执行对移动终端的控制动作。还可以从获取移动终端与多天线节点之
间的第一个位置关系信息开始,到达第二预设位置关系数量,例如M个时,执行对移动终端的控制动作。
例如,设定具体位置关系信息,即,当获取的移动终端与多天线节点之间的位置关系信息表明移动终端跨域了室内外临界区域的界限,例如方位角从0-90°变化至90-180°,则表明移动终端已经从室外进入室内,则执行对移动终端的控制动作。
本发明实施例中,移动终端以第一方式控制移动终端,例如可以包括:控制所述移动终端使用与室内匹配的定位方式,或,控制所述移动终端加载室内导航地图。
例如,当移动终端和多天线节点的位置关系的变化信息,表明移动终端的运动趋势为从室外向室内运动时,则对应于这种运动趋势,控制移动终端采用室内定位方式或加载室内导航地图,从而与室内的定位方式相匹配。
与室内匹配的定位方式例如:Wi-Fi定位、蓝牙定位、磁场定位或光线定位等。
需要说明的是,本发明实施例中,移动终端以第二方式控制移动终端,例如可以包括:控制所述移动终端使用与室外匹配的定位方式,或,控制所述移动终端加载室外导航地图。
例如,当移动终端和多天线节点的位置关系的变化信息,表明移动终端的运动趋势为从室内向室外运动时,则对应于这种运动趋势,控制移动终端采用室外定位方式或加载室外导航地图,从而与室外的定位方式相匹配。
与室外匹配的定位方式包括:GNSS定位、蜂窝网络定位或Wi-Fi定位。
其中,Wi-Fi定位例如可以是:多个Wi-Fi热点向周围发射信号,移动终端检测每个热点的信号强弱,把检测到的信号强弱信息发送给服务器,服务器根据这些信息,查询每个热点在数据库里记录的坐标,进行运算,从而实现移动终端的定位。
蓝牙定位例如可以是:蓝牙向周围发射信号,带有蓝牙模块的移动终端通过接收这些蓝牙的信号,识别其ID确定移动终端所在的位置。
磁场定位是指:构建磁场地图,利用周围磁场的波动情况来确定移动终端在室内的位置。
光线定位可以包括红外光或可见光定位,例如,白光LED定位,是利用LED灯光发出的肉眼看不见的高速明暗闪烁信号来实现移动终端的定位。
GNSS定位,泛指所有的利用卫星导航系统实现的定位。
蜂窝网络定位,是指利用基站信号对移动终端进行的定位。
上述各种定位方式均属于现有技术,在此不再详述。
下面举例说明如何对移动终端进行控制。
例如,移动终端位于室外,室外定位单元(以GNSS中的GPS为例)GPS正在对移动终端进行定位,当通过本发明实施例的方法,移动终端获取了移动终端与多天线节点之间的位置关系的变化信息,该变化信息表明移动终端正在从室外向室内运动时,例如:移动终端与多天线节点之间的方位角变化为时,使用移动终端中的室内定位单元,如Wi-Fi或蓝牙。移动终端可以预设各室内定位单元使用的优先级,以在使用室内定位单元时,优选优先级最高的室内定位单元;还可以使用室内定位单元时,同时将多个室内定位单元打开,由各室内定位单元的信号强度决定使用哪一个定位单元实现室内定位。在使用室内定位单元时,可以关闭室外的定位单元,也可以保持室外定位单元的开启状态。如果关闭室外定位单元,则直接以室内定位单元的定位结果为准;如果保持室外定位单元的开启状态,则可以通过比较室内、室外定位单元二者的定位结果,若二者距离近,加权叠加二者的结果作为输出,若二者距离远,直接以新开始的系统为准。可以在移动终端中设置如何控制室外定位单元的状态,即保持开启、还是关闭。
使用室内定位单元后,该室内定位单元处于信号收发状态,能够对移
动终端进行室内定位。
另外,当变化信息表明移动终端正在从室外向室内运动时,还可以加载室内导航地图,使得室内外导航地图无缝连接。
还例如,移动终端位于室内,室内定位单元正在对移动终端进行定位,当通过本发明实施例的方法,移动终端获取了移动终端与多天线节点之间的位置关系的变化信息,该变化信息表明移动终端正在从室内向室外运动时,使用移动终端中室外定位单元,如GPS或蜂窝网络。移动终端可以预设各室外定位单元使用的优先级,以在使用室外定位单元时,优选优先级最高的室外定位单元;还可以在使用室外定位单元时,同时将多个室外定位单元打开,由各室外定位单元的信号强度决定使用哪一个定位单元实现室外定位。在使用室外定位单元时,对室内定位单元的控制,例如可以与在使用室内定位单元时,对室外定位单元的控制相同。
使用室外定位单元后,该室外定位单元处于信号收发状态,能够对移动终端进行室外定位。
另外,当变化信息表明移动终端正在从室内向室外运动时,还可以加载室外导航地图,使得室内外导航地图无缝连接。
可选择的,本发明实施例在所述获取所述移动终端与多天线节点之间的位置关系的变化信息之前,还包括根据定位信号的变化,移动终端与多天线节点建立无线连接。
例如,当所述移动终端接收到可视卫星的数目小于或等于第一阈值时,或者,当所述移动终端检测到Wi-Fi或蓝牙信号强度大于或等于第二阈值时,或者,当所述移动终端检测到Wi-Fi接入点的数量或蓝牙节点的数量大于或等于第四阈值时,表明移动终端的室内定位信号变弱,移动终端可能正在向室外方向运动,此时,所述移动终端与所述多天线节点建立无线连接。
例如,当所述移动终端检测到Wi-Fi或蓝牙信号强度小于或等于第三阈值时,或者,当所述移动终端检测到Wi-Fi接入点的数量或蓝牙节点的
数量小于或等于第五阈值时,表明移动终端的室内定位信号变弱,移动终端可能正在向室外方向运动,此时,所述移动终端与所述多天线节点建立无线连接。
需要说明的是,由于Wi-Fi信号与蓝牙信号的信号类型不同,强度级别也不同,当分别采用Wi-Fi定位或蓝牙定位时,上述第二阈值的强度大小不同,该第二阈值根据定位方式赋予不同的数值。
可选择的,本发明实施例中,在接收多天线节点在N个时刻分别发送的N个测向信号之前,移动终端仅开启正在使用的定位单元,而不开启其他的定位单元。仅当移动终端检测到当前定位单元的定位信号发生变化时,即初步判断移动终端可能正在运动中,或正靠近室内、或正靠近室外时,才开启移动终端中的其他定位单元。
例如,当移动终端位于室外时,仅开启GPS定位单元,关闭移动终端中的其他定位单元。仅当,移动终端检测到GPS定位信号产生降低时,才开启其他定位单元,如Wi-Fi。
采用这样的方案,避免了一直同时开启多个定位单元,定位单元不停的寻找信号而产生的功耗浪费。
由于多天线节点的信号类型可能与移动终端正在使用的定位单元的信号类型不同,而无法在移动终端和多天线节点之间建立连接。当移动终端检测到正在使用的定位单元的信号产生变化时,开启其他定位单元后,就可以通过某一与多天线节点相一致的定位信号与多天线节点建立连接,以获得相对精确的移动终端的位置信息。
本发明实施例提供的移动终端的控制方法,接收多天线节点发送的多个测向信号,并根据多个测向信号,可以获取在一段时间内移动终端和多天线节点之间的位置关系的变化信息,然后根据位置关系的变化信息,以与该变化信息匹配的方式控制移动终端;由于位置关系的变化信息可以准确的表示移动终端从室内向室外运动的运动趋势或者移动终端从室外向室内运动的运动趋势,从而可以基于准确的运动趋势来控制移动终端,提高了移动终端
在开启室内或室外的定位方式方面的控制准确性,以及加载室内或室外地图控制方面的准确性。
图6为本发明实施例的另一种移动终端的控制方法的流程图。如图6所示,
步骤601、移动终端向在N个时刻分别向位于室内外临界区域的多天线节点发送N个测向信号;多天线节点接收移动终端在N个时刻分别发送的N个测向信号。
多天线节点位于室内外临界区域,处于信号收发状态。
其中,所述多天线节点包括:多天线Wi-Fi节点或多天线蓝牙节点。
当移动终端检测到多天线节点的信号时,则开始向多天线节点发送测向信号,同时多天线节点开始接收移动终端发出的测向信号。
步骤602、多天线节点根据所述N个测向信号,获取在N个时刻时所述多天线节点与所述移动终端之间的N个位置关系信息,所述N个时刻与所述N个位置关系信息一一对应。
具体来说,当移动终端在某一时刻发送了一个测向信号,多天线节点接收到该测向信号时,例如可以通过:2D MUSIC算法、2D FBSS算法、FBSS-DOAM算法或ESPRIT算法等来计算多天线节点与移动终端之间的方位角和仰角θ,移动终端与多天线节点之间的方位角和仰角θ的信息即为移动终端与多天线节点之间的位置关系信息。
多天线节点接收所述移动终端在N个时刻分别发送的N个测向信号;并根据所述N个测向信号,获取在所述N个时刻时所述多天线节点与所述移动终端之间的N个方位角和N个仰角θ,即多天线节点与移动终端之间的位置关系信息;所述多天线节根据所述N个位置关系信息,确定所述多天线节点与所述移动终端之间的位置关系的变化信息。
步骤603、所述多天线节点根据所述N个位置关系信息中的至少M
个,确定所述多天线节点与所述移动终端之间的位置关系的变化信息,2≤M≤N。
如果移动终端在运动中,那么在N个时刻获取的多天线节点与移动终端之间的位置关系是变化的。多天线节点可以根据N个时刻获取的多天线节点与移动终端之间的位置关系信息获取多天线节点与移动终端之间的位置关系的变化信息。位置关系的变化信息表示多天线节点相对于移动终端的方位角和仰角的变化的信息,用于表示移动终端的运动趋势,即,移动终端从室外向室内运动,还是从室内向室外运动。
例如,当获取的N个时刻的N个位置关系信息为以及θ1、θ2、…、θN时,可以根据N个位置关系信息来确定多天线节点与移动终端之间的位置关系的变化信息,还可以选择N个位置关系信息中的M个位置关系信息来确定多天线节点与移动终端之间的位置关系的变化信息,M个位置关系信息可以是N个中连续选取的几个,也可以是间隔顺序选取的几个,其中,M≤N。
步骤604、所述多天线节点根据所述位置关系的变化信息,向所述移动终端发送与所述位置关系的变化信息相匹配的控制命令;所述移动终端接收所述多天线节点根据所述N个测向信号返回的控制命令。
根据多天线节点与移动终端之间的位置关系的变化信息,能够确定移动终端是从室内向室外运动,还是从室外向室内运动,多天线节点向移动终端发送与该运动趋势,即位置关系的变化信息相匹配的控制命令。
下面将结合附图5具体说明多天线节点如何向移动终端发送与位置关系的变化信息相匹配的控制命令。
当时,如果多天线节点与移动终端之间的方位角逐渐增加,即位置关系的变化信息为则表明移动终端的运动趋势为从室外向室内运动,那么多天线节点对应于这种运动趋势,向移动终端发送第一命令,移动终端相应接收第一命令;如果多天线节点与移动终端之间的方位角逐渐增加,即位置关系的变化信息为
则表明移动终端的运动趋势为从室内向室外运动,那么多天线节点对应于这种运动趋势向移动终端发送第二命令,移动终端相应接收第二命令,其中,为第i个时刻的方位角,1≤i≤M,M≤N。
当时,如果多天线节点与移动终端之间的方位角逐渐减小,即位置关系的变化信息为则表明移动终端的运动趋势从室外向室内运动,那么多天线节点对应于这种运动趋势,向移动终端发送第一命令,移动终端相应接收第一命令;如果多天线节点与移动终端之间的方位角逐渐增加,即位置关系的变化信息为则表明移动终端的运动趋势为从室内向室外运动,那么多天线节点对应于这种运动趋势向移动终端发送第二命令,移动终端相应接收第二命令,其中,为第i个时刻的方位角,1≤i≤M,M≤N。
当或时,如果多天线节点与移动终端之间的方位角不变,仰角逐渐减小,即位置关系的变化信息为
且θ1>θ2>…>θM>0,则表明移动终端的运动趋势为从室外向室内运动,多天线节点对应于这种运动趋势向移动终端发送第一命令,移动终端相应接收第一命令;如果多天线节点与移动终端之间的方位角不变,仰角逐渐增加,即位置关系的变化信息为且0<θ1<θ2<…<θM,则表明移动终端的运动趋势为从室内向室外运动,多天线节点向对应于这种运动趋势移动终端发送第二命令,移动终端相应接收第二命令,其中,为第i个时刻的方位角,θi为第i个时刻的仰角,1≤i≤M,M≤N。
当时,如果多天线节点与移动终端之间的方位角不变,仰角逐渐增加,即位置关系的变化信息为且0<θ1<θ2<…<θM,则表明移动终端的运动趋势从室外向室内运动,多天线节点对应于这种运动趋势向移动终端发送第一命令,移动终端相应接收第一命令;如果多天线节点与移动终端之间的方位角不变,仰角逐渐减小,即位置关系的变化信息为且θ1>θ2>…>θM>0,则表明移动终端的运动趋势从室内向室外运动,多天线节点对应于这种运动趋势向移动终端发
送第二命令,移动终端相应接收第二命令,其中,为第i个时刻的方位角,θi为第i个时刻的仰角,1≤i≤M,M≤N。
可选的,为了更加准确的判断移动终端的运动趋势,还可以基于以下四种条件中的任意一种,来根据位置关系的变化信息,选择与位置关系的变化信息相匹配的控制方式发出控制命令,来控制移动终端的操作。
第一条件,当时,如果多天线节点与移动终端之间的方位角逐渐增加,仰角逐渐减小,即位置关系的变化信息为

第四条件,当时,如果多天线节点与移动终端之间的方位角逐渐增加,仰角逐渐增加,即位置关系的变化信息为
且θ1<θ2<…<θM,则表明移动终端的运动趋势为从室内向室外运动,那么多天线节点对应于这种运动趋势向移动终端发送第二命令,移动终端相应接收第二命令;如果多天线节点与移动终端之间的方位角逐渐减小,仰角逐渐减小,即位置关系的变化信息为且θ1>θ2>…>θM,则表明移动终端的运动趋势为从室外向室内运动,那么多天线节点对应于这种运动趋势向移动终端发送第一命令,移动终端相应接收第一命令。
需要说明的是,本发明实施例中获取N个时刻时多天线节点与移动终端之间的N个位置关系信息,但是发送第一/第二命令的动作,可以选取不同时间点。例如,设定预设时长、设定获取位置关系的数量、设定具体位置关系信息。具体参见步骤104中,对预设时长、获取位置关系的数量、具体位置关系信息的说明,在此不再赘述。
步骤605、所述移动终端执行所述控制命令。
移动终端接收多天线节点发送的控制命令后,执行相应的控制命令。
当控制命令为第一命令时,所述移动终端使用与室内匹配的定位方式,或加载室内导航地图。
当控制命令为第二命令时,所述移动终端使用与室外匹配的定位方式,或加载室外导航地图。
可选择的,本发明实施例在获取所述多天线节点与所述移动终端之间的位置关系的变化信息之前,还包括所述多天线节点与所述移动终端之间
建立无线连接。
本发明实施例提供的另一种移动终端的控制方法,移动终端向多天线节点发送多个测向信号,多天线节点接收多个测向信号后,根据多个测向信号,可以获取在一段时间内多天线节点与移动终端之间的位置关系的变化信息,然后根据位置关系的变化信息,移动终端接收多天线节点发出的与该变化信息匹配控制命令,并执行该控制命令;由于位置关系的变化信息可以准确的表示移动终端从室内向室外运动的运动趋势或者移动终端从室外向室内运动的运动趋势,从而可以基于准确的运动趋势来控制移动终端,提高了移动终端在开启室内或室外的定位方式方面的控制准确性,以及加载室内或室外地图控制方面的准确性。
本发明实施例进一步给出实现上述方法实施例中各步骤及方法的移动终端的控制装置。
需要说明的是,上述各方法实施例中,以移动终端或者多天线节点作为执行主体进行说明。在具体实现方式中,也可以由移动终端中的一个或多个芯片或者多天线节点中的一个或多个芯片作为执行主体。
上述各方法实施例中,描述了一个多天线节点与移动终端进行通信的技术方案。在具体实现方式中,可以在室内外临界区域中设置多个多天线节点;终端在处于室内外临界区域附近时,可以与多个多天线节点进行通信;通过移动终端与每个多天线节点之间的位置关系(例如方位角或仰角),可以定位出移动终端的具体位置;通过移动终端在多个时刻的具体位置,可以更加准确的判断出移动终端的运动趋势,进而更加准确的控制移动终端。
上述各方法实施例中,描述了一个移动终端与多天线节点进行通信的技术方案。在具体实现方式中,可以多个移动终端进行配合来完成本实施例中的方案。例如:手机和穿戴式设备(例如智能手环、智能眼镜)的配合;智能手环接收多天线节点发送的多个测向信号后,将测向信号发送给手机进行处理;手机根据该测向信号得到手环与多天线节点之间的位置关系信息;由于手环和手机在同一个用户身上,所以手环与多天线节点之间的位置关系和
手机与多天线节点之间的位置关系相同;进而可以对手机或手环进行相应的控制。
在另一种实现方式中,还可以根据终端之前的位置信息和终端当前所处的位置来控制终端。例如:终端之前使用室外方式定位,通过终端与多天线节点配合计算出终端当前处于室内,如:90°≤方位角则说明终端已经从室外移动到了室内,可以控制终端使用室内方式定位。又例如:终端之前加载的室内导航地图,通过终端与多天线节点配合计算出终端当前处于室外,如:0°≤方位角或270°≤方位角则说明终端已经从室内移动到了室外,可以控制终端加载室外导航地图。
