附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对实施例的描述中所需要使用的附图作简单的介绍。下面描述中的附图仅仅是本公开的示例性实施例。
图1示出了根据本公开实施例的移动设备结构示意图；
图2示出了根据本公开实施例的移动设备天线切换示意图；
图3示出了根据本公开实施例的移动设备中是相控阵液晶天线的结构示意图；

具体实施方式
在下文中，将参考附图详细描述本公开的优选实施例。注意，在本说明书和附图中，具有基本上相同步骤和元素用相同的附图标记来表示，且对这些步骤和元素的重复解释将被省略。
在本公开的以下实施例中，移动设备是指可以在移动中通过无线网络进行通信或上网的电子设备，例如包括手机、笔记本、平板电脑、POS机、车载电脑。进一步的，移动设备可以具有多种应用功能和一定处理能力，例如智能手机。
图1示出了根据本公开实施例的移动设备结构示意图。参见图1，移动设备100包括：方向传感器110，信号处理单元120，定向天线单元130。
根据本公开的一个示例，所述方向传感器110，检测移动设备100的当前移动方向。信号处理单元120，根据移动设备的当前移动方向确定定向天线单元130的天线调节方向，其中所述天线调节方向与所述移动设备的当前 移动方向相关。定向天线单元130，根据天线调节方向，将天线方向从第一方向调节到第二方向，所述天线调节方向和第二方向是移动设备的运动方向或运动方向上的最近一个基站所在的方向。
在本公开的一个实施例中，方向传感器110被配置为检测移动设备当前移动方向。方向传感器110例如可以包括陀螺仪和/或加速度传感器。
陀螺仪可以测量移动设备100的相对偏转角度。陀螺仪内部有一个陀螺，它的轴由于陀螺效应始终与初始方向平行，这样就可以通过与初始方向的偏差计算出实际方向。例如，移动设备中陀螺仪传感器具有一个结构非常精密的芯片，内部可以包含超微小的陀螺。陀螺仪传感器测量参考标准是内部中间在与地面垂直的方向上进行转动的陀螺。通过移动设备100与陀螺的夹角得到结果，因此可以在移动设备中安装陀螺仪以确定移动设备在地球坐标系中相对于X轴，Y轴，Z轴三个方向上分别偏移了多少度。
加速度传感器可以测量移动设备的移动加速度。例如，加速度传感器可以是三轴加速度传感器，用于测量移动设备在三个方向上的角度。加速度传感器由于加速度产生某个介质产生变形，通过测量其变形量并用相关电路转化成电压输出。移动设备100在任何方向上运动，加速度传感器就会有信号输出，移动设备100静止不动时加速度传感器则没有信号输出。
通过陀螺仪和/或加速度传感器可以计算移动设备的移动方向。例如，移动设备是在移动状态还是静止状态。向哪个方向移动，移动速度、加速度等等。可以根据地球坐标系，精确检测移动设备100的在XYZ三轴上的移动方向。相比其它方式，使用陀螺仪和/或加速度传感器计算移动设备的移动方向时，其系统结构及算法更简单、成本更低。当然，陀螺仪以及加速度传感器仅仅是示例，本领域技术人员应当了解，还可以使用其他方式来获取移动设备的移动方向等参数。
信号处理单元120根据移动设备的当前移动方向确定定向天线单元130的天线调节方向，该天线调节方向与移动设备的当前移动方向相关。
根据本公开的一个示例，天线调节方向与移动设备的当前移动方向一致。例如，当信号处理单元120确定移动设备当前移动方向为向正南方向移动时，可以直接将正南方向确定为定向天线单元130的天线调节方向。图2示出了根据本公开实施例的移动设备天线切换示意图。例如，参见图2，移动设备100从A向B移动，而A，B分属于不同小区。根据本公开实施例，当判断 出移动设备100从A向B移动时，可以将其天线方向从当前方向调节为沿A向B的连线方向并朝向B。
可替换的，天线调节方向也可以是在当前移动方向的基础上进行必要校正后的方向。例如，在确定移动设备的当前移动方向后，根据累计误差等对当前移动方向进行校正，将校正后的方向作为天线调节方向。
定向天线单元130，根据所述天线调节方向，将移动设备100的天线方向从第一方向调节到第二方向。与普通天线不同，定向天线单元130可以控制天线的在一特定方向接收信号和发射信号，而普通天线可以朝四周辐射信号，进行信号的接收和发送。根据本公开的一个示例，定向天线可以是相控阵定向天线或超材料天线中的至少一个。
超材料是由周期性或非周期性人造微结构排列而成的人工复合材料通过复杂的人造微结构设计与加工，实现人造“原子”对电磁场或者声纳的响应。超材料定向天线例如可以是将定向天线嵌入零折射率的超材料中，得到零折射率高定向性定向天线。还可以是网格状结构零折射率超材料置于定向天线上方的高定向型微带天线等等。
相控阵定向天线通过控制阵列定向天线中辐射单元的馈电相位来改变方向。控制相位可以改变定向天线方向图最大值的指向，以达到波束扫描的目的。它的馈电相位一般用电子计算机控制，相位变化速度快，例如毫秒量级，即定向天线方向图最大值指向或其他参数的变化迅速。
根据本公开的一个示例，相控阵定向天线可以是相控阵液晶天线。图3示出了根据本公开实施例中相控阵液晶天线的结构示意图。参见图3，相控阵液晶天线300包括配电电极310，液晶移相器320以及辐射电极330。
图8示出了根据本公开实施例的移动设备的另一种结构示意图。参见图8，根据本公开的一个示例，信号处理单元120包括信号接收器和信号调节器，信号接收器获取到天线调节方向信息时发送给信号调节器，信号调节器将该天线调节方向的信息从数字信号调制为模拟信号。然后，信号处理单元120将该模拟信号发送给相控阵液晶天线300。这样，相控阵液晶天线300基于该模拟信号调节配电电极310的电压，以调节液晶移相器320的液晶介电常数；并基于介电常数的改变，调节辐射电极330发射/接收的电磁波的相位，从而改变相控阵液晶天线的方向。此处，信号调节器包括与相控阵液晶天线连接的驱动芯片。可选地，信号调节器可以包括AD转换器，信号放大器或 解码器的一种或任意组合。比之传统的机械方法旋转定向天线，相控阵液晶天线调节速度快，且精度高。
本公开实施例根据移动设备的移动方向来改变定向天线的方向，使天线的方向朝向移动设备的移动方向，从而使得移动方向上的信号强度最大，这样，移动设备可以及时与移动方向的下一个小区建立连接，减少或避免了通信迟滞问题的发生。
图4示出了根据本公开实施例的移动设备的另一结构示意图。参见图4移动设备还可以包括通信单元140。通信单元140响应于定向天线方向从第一方向调节到第二方向，与第二方向上的信号小区建立连接并进行通信。例如，通信单元140可以获取第二方向上的信号小区的通信参数，基于通信参数与该小区建立连接。例如，通信单元140可以首先获取该下一个小区的通信协议，根据该通信协议与该小区建立连接，以接收和发送信息。可选的，当第二方向上有多个信号小区时，通信单元140也可以与多个小区分别建立连接。可选地，通信单元140也可以在信号处理单元120确定天线调节方向后，根据该天线调节方向与该调节方向上的信号小区建立连接。也就是说，与下一个小区建立连接的操作可以在天线方向调节之前，同时或之后任何时候进行。
图5示出了根据本公开实施例的移动设备的另一结构示意图。参见图5，在移动设备100中，信号处理单元120还包括信号检测单元1201。
信号检测单元1201基于天线调节方向，检测该信号调节方向上所在的信号小区的信号，当检测到该方向的信号小区的信号后，信号处理单元120向定向天线单元130发送天线调节指令，定向天线单元130根据定向天线调节指令以及天线调节方向，将天线方向从第一方向调节到第二方向。例如，当信号处理单元120根据移动设备的当前移动方向确定了天线调节方向，此时，信号检测单元1201还要进一步检测天线调节方向所朝向的信号小区的信号，仅当检测到了该方向上的某个小区的信号时，才向定向天线单元130发送天线调节指令，以使天线方向从第一方向调节到第二方向。例如，参见图2，当信号处理单元120确定移动设备100从A向B移动，此时，信号检测单1201还要进一步检测B位置所属信号小区的信号，直到检测到该小区信号，信号处理单元120才发送天线调节指令。如果当移动设备在A位置时就进行天线方向切换，则可能导致移动设备100与A位置所在小区连接不上，由于移动 设备100又没有达到B位置，也接收不到B位置信号小区的信号，则会造成网络连接不上或网络延迟的问题。因此，本公开该实施例可以有效避免网络连接不上或网络延迟的问题。
根据本公开的另一个示例，当检测到所述信号调节方向上的信号小区的信号后，所述信号检测单元1201还可以进一步判断该信号小区的信号强度，当信号强度大于预设强度阈值时，所述信号处理单元120向所述定向天线单元130发送所述天线调节指令以调节天线方向。其中预设强度阈值例如可以是信号强度到达标准强度的30％或50％。还例如，当信号检测单元130在移动设备100的移动方向上检测到多个信号小区的信号后，可以将天线调节到信号最强的小区的方向，通信单元可以与信号最强的小区建立连接。以上示例可以避免移动设备与多个小区建立连接而造成的资源浪费，同时也可以避免太早切换而造成的接收不到当前小区信号的情况发生。
图6示出了根据本公开实施例的移动设备的再一结构示意图。参见图6,移动设备100还可以包括定位装置150。定位装置150可以检测移动设备100的当前位置。这样，信号处理单元120可以根据移动设备100的当前位置以及当前移动方向确定定向天线单元130的天线调节方向。例如，移动设备100中可以预先存储有各个小区位置的地图，这样，根据移动设备当前位置以及移动方向，就可以确定移动设备100将要进入的下一个小区是哪个小区，并且根据预先存储的各个小区地图，将天线单元调节到朝向该小区的方向。进一步的，还可以根据预先存储的信号小区地图，确定该信号小区的基站的位置。这样，信号处理单元120可以基于该基站的位置确定定向天线单元的天线调节方向。例如，将天线单元调节到朝向该基站发射接收信号的方向。这样可以保证移动设备发送接收信号的角度最佳。
根据本公开的一个示例，当信号处理器120根据移动设备100的当前位置以及当前移动方向确定移动设备可能进入多个信号小区时，例如，第一信号小区和第二信号小区。此时，信号处理器120中的信号检测单元1201可以检测第一信号小区以及第二信号小区的信号强度，并确定哪个信号小区的信号强度最大，将信号强度最大的信号小区确定为移动设备准备进入的下一个信号小区。并将天线调节到朝向该信号小区。
本公开实施例，可以根据移动设备的当前移动方向以及其他辅助参数确定移动设备的天线调节方向，可以更精确的确定天线调节方向，有效避免了 由于接收不到信号造成的网络延迟的技术问题。
以上介绍了根据本公开实施例的移动设备的结构和工作方式，下面将进一步介绍根据本公开实施例的移动设备天线调节方法。该天线调节方法为前述实施例中的移动设备中天线的调节方法，因此与移动设备的结构和功能对应，为了说明书的简洁，在此仅对该方法进行简要描述，具体内容可以参考前述实施例中的移动设备。

在步骤S702中，根据当前移动方向确定移动设备中的定向天线单元的天线调节方向，天线调节方向与当前移动方向相关。
