下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的天线切换进行详细地说明。
该天线切换方法应用于电子设备，所述电子设备包括M个天线，M为大于1的整数，图1是本申请实施例提供的天线切换方法的流程图，如图1所示，包括以下步骤：
步骤101，在所述M个天线中进行通信的天线为第一天线的情况下，识 别所述电子设备所处的第一使用场景。
电子设备包括的M个天线中可以包括两种类型的天线，分别为主天线和辅天线，所述第一天线可以为主天线，也可以为辅天线，这里不进行具体限定。
主天线和辅天线通常具备一定的辐射性能差异，且主天线的辐射性能通常比辅天线的辐射性能好。因此，电子设备进行通信的天线通常默认为所述M个天线中的主天线，即在一可选实施方式中，第一天线可以为M个天线中的主天线。
通常情况下，电子设备中可以包括一个主天线，而辅天线的数量可以根据实际情况进行设置，如电子设备中包括4个天线，可以设置天线1为主天线，设置天线2、天线3和天线4均为辅天线。
电子设备通过天线进行通信的情况下，在一些使用场景下，由于天线遮挡和周围环境等原因，会极大地影响天线对信号的接收，且电子设备处于不同使用场景时，对天线信号接收的影响程度会有所不同。在该种情况下，需要将该天线切换至其他天线上进行通信，以保证电子设备始终工作在性能更好的天线上，从而保证电子设备的通信性能。
在检测到所述M个天线中进行通信的天线为第一天线(该第一天线可以为主天线)的情况下，可以识别电子设备所处的第一使用场景。其中，可以通过现有的或新的检测方式，来检测所述M个天线中进行通信的天线是否为第一天线，这里不进行具体限定。
其中，可以将所述M个天线中进行通信的天线定义为第一天线，也可以将M个天线中主天线定义为第一天线，可以通过设置通信标识，来检测所述M个天线中进行通信的天线是否为第一天线。
在一可选实施方式中，可以将通信标识为数值1的天线确定为第一天线。
在另一可选实施方式中，若将M个天线中主天线定义为第一天线，在主天线的通信标识为数值1，而其他天线的通信标识为0时，则可以确定所述M个天线中进行通信的天线为第一天线，而在主天线的通信标识为0，而其他天线中某一天线的通信标识为1时，则可以确定所述M个天线中进行通信的天线不为第一天线。
所述电子设备所处的第一使用场景可以指的是：在所述M个天线中进行通信的天线为第一天线的情况下，用户对电子设备的使用场景，即在所述M个天线中进行通信的天线为第一天线的情况下，电子设备所处的使用场景，包括但不限于单手握、双手握、头手效应和身体遮挡等预设使用场景。
单手握可以指的是用户通过一只手使用电子设备，双手握可以指的是用户通过两只手“捧式”地使用电子设备，头手效应可以指的是用户使用电子设备时头部和手部靠近电子设备的听筒，比如用户使用电子设备打电话时的使用场景，则属于头手效应，而身体遮挡可以指的是用户使用电子设备时电子设备放置在遮挡位置，比如类似于电子设备放置在口袋(上衣口袋或裤子口袋等)中。
所述电子设备所处的使用场景的识别方式可以有多种，比如，可以利用电子设备中的一个或多个传感器，来识别电子设备所处的使用场景，在利用电子设备的多个传感器来识别电子设备所处的使用场景时，该多个传感器可以为相同的传感器，也可以为不同的传感器，这里不进行具体限定。
该多个传感器可以包括但不限于近距离传感器和红外传感器等，举几个例子来说，针对单手握和双手握的使用场景，可以通过在电子设备的上部分和下部分分别设置一个近距离传感器来进行识别，在设置在下部分的近距离传感器检测到有物体接近的情况下，则可以识别电子设备所处的使用场景为单手握，而在设置在上部分和下部分的近距离传感器均检测到有物体接近的情况下，则可以识别电子设备所处的使用场景为双手握。
针对头手效应的使用场景，可以通过设置在听筒附近的近距离传感器或红外传感器，来检测电子设备与大脑之间的距离，以在大脑靠近电子设备时，识别电子设备所处的使用场景为头手效应。
针对身体遮挡的使用场景，可以通过近距离传感器和红外传感器，来检测电子设备与身体各个部位之间的距离，在近距离传感器检测到电子设备远离用户手部，且红外传感器检测到电子设备靠近用户身体部位的情况下，识别电子设备所处的使用场景为身体遮挡。
也可以利用电子设备中的听筒，来识别头手效应的使用场景，举个例子来说，在检测到听筒处于使用状态的情况下，可以识别电子设备所处的使用 场景为头手效应。
还可以通过接收用户输入的信息，基于用户输入的信息来识别所述电子设备所处的使用场景。其中，用户输入的信息可以为表征所述电子设备当前所处的使用场景的相关信息。
步骤102，获取所述第一使用场景对应的不平衡阈值，所述不平衡阈值用于表征在所述第一使用场景中所述第一天线与所述M个天线中其他天线的第一辐射性能差异。
该步骤中，受实际的天线架构、走线方式、材料选择、实际使用场景、以及天线固有性能等因素的影响，不同天线之间会存在一定的辐射性能差异。
其中，辐射性能可以通过全向辐射功率(Total Radiated Power，TRP)指标和全向接收灵敏度(Total Isotropic Sensitivity，TIS)指标来表征，TPR可以反映在整个辐射球面电子设备的接收灵敏度的情况，TIS可以反映整机的发射功率情况。
不同天线之间的辐射性能差异可以包括第一辐射性能差异，该第一辐射性能差异指的是受实际的天线架构、走线方式、材料选择、以及实际使用场景等因素的影响，而导致的不同天线之间的辐射性能差异。其具体产生的原因是受实际的天线架构、走线方式、材料选择、以及实际使用场景等因素的影响，不同天线之间(包括主天线和辅天线之间)会存一定的不平衡性，这种不平衡性量化成的数值可以称之为不平衡阈值，该不平衡阈值可以表征第一天线与其他天线的第一辐射性能差异。
另外，受不同使用场景的影响，由于天线遮挡和周围环境等的不同，不同使用场景下所述第一天线与所述M个天线中其他天线的不平衡阈值会有所不同，即不同使用场景中所述第一天线与所述其他天线的第一辐射性能差异会有所不同。因此，可以获取所述电子设备当前所处的使用场景对应的不平衡阈值，将该不平衡阈值作为天线切换的依据。
可以在预设寄存器中查询所述电子设备当前所处的使用场景对应的不平衡阈值，该预设寄存器中可以以表格的形式存储不同使用场景下的不平衡阈值，且这些不平衡阈值可以是预先测试并存储在该预设寄存器中的。
具体的，可以采用以下方式获取不同使用场景下对应的不平衡阈值。
数据收集，针对电子设备中的每个天线，在该天线进行通信时，可以分使用场景(如单手握、双手握、身体遮挡、头手效应)在暗室中模拟测试，取得使进行通信的天线的TRP和TIS最优时，该天线和其他天线之间的不平衡阈值，如表1所示。
表1针对每个天线，不同使用场景下对应的不平衡阈值
| 使用场景 | 不平衡阈值 |
| 单手握 | A |
| 双手握 | B |
| 身体遮挡 | C |
| 头手效应 | D |
将每个天线在不同使用场景中对应的不平衡阈值以表格的形式存储在预设寄存器中，以供后续依据电子设备实际所处的使用场景选取对应的不平衡阈值。
具体的，可以获取所述第一天线在不同使用场景中对应的不平衡阈值，之后从所述第一天线在不同使用场景中对应的不平衡阈值中获取所述第一使用场景对应的不平衡阈值。
步骤103，基于所述不平衡阈值将所述第一天线切换至所述其他天线中的天线进行通信。
该步骤中，可以将不平衡阈值作为该使用场景下天线切换的依据，在一可选实施方式中，可以将所述不平衡阈值作为第一天线和其他天线之间的辐射性能差异的阈值，在所述其他天线中存在第二天线的情况下，可以将所述第一天线切换至所述第二天线进行通信，该第二天线的接收信号强度与第一天线的接收信号强度的第一差值大于所述不平衡阈值。
在另一可选实施方式中，受天线固有性能等因素的影响，不同天线之间(包括主天线和辅天线之间)会存在固有的辐射性能差异，该固有的辐射性能差异可以用基础阈值来表征，其用于表征所述第一天线与所述其他天线的第二辐射性能差异，而所述不平衡阈值和基础阈值的和即用于表征所述第一天线与所述其他天线之间总体的辐射性能差异。
可以将所述不平衡阈值和基础阈值的和作为第一天线和其他天线之间的 辐射性能差异的阈值，在所述其他天线中存在第二天线的情况下，可以将所述第一天线切换至所述第二天线进行通信，该第二天线的接收信号强度与第一天线的接收信号强度的第一差值大于所述不平衡阈值和基础阈值的和。
另外，在所述其他天线中不存在第二天线的情况下，可以不进行天线切换，或者，在第一天线的接收信号强度小于某一阈值，即第一天线的辐射性能比较差时，可以将第一天线切换至所述其他天线中的第三天线进行通信，该第三天线为所述其他天线中接收信号强度与第一天线的接收信号强度的第一差值最大的天线。
本实施例中，通过在电子设备中设置M个天线，并在所述M个天线中进行通信的天线为第一天线的情况下，识别所述电子设备所处的第一使用场景；获取所述第一使用场景对应的不平衡阈值，所述不平衡阈值用于表征在所述第一使用场景中所述第一天线与所述M个天线中其他天线的第一辐射性能差异；基于所述不平衡阈值将所述第一天线切换至所述其他天线中的天线进行通信。如此可以提供一种更加贴合用户实际使用场景的天线切换，使得天线切换更合理，且更为灵活、准确和可靠，从而可以提高天线切换的效果。
可选的，所述步骤103具体包括：
基于所述不平衡阈值和预设的基础阈值，确定所述第一天线与所述其他天线的辐射性能差异阈值，所述基础阈值用于表征所述第一天线与所述其他天线的第二辐射性能差异；
在所述其他天线中存在至少一个第二天线的情况下，将所述第一天线切换至任一个所述第二天线进行通信，所述第二天线的接收信号强度与所述第一天线的接收信号强度的第一差值大于所述辐射性能差异阈值。
本实施方式中，受天线固有性能等因素的影响，不同天线之间(包括主天线和辅天线之间)通常会存在固有的辐射性能差异，该固有的辐射性能差异可以用基础阈值来表征。
所述预设的基础阈值可以为所述第一天线对应的基础阈值，其用于表征所述第一天线与所述其他天线的第二辐射性能差异。
可以将不平衡阈值和预设的所述基础阈值相加得到的和确定为所述第一天线与所述其他天线的辐射性能差异阈值，并在所述其他天线中存在至少一 个第二天线的情况下，将所述第一天线切换至任一个所述第二天线进行通信，所述第二天线的接收信号强度与所述第一天线的接收信号强度的第一差值大于所述辐射性能差异阈值。
本实施方式中，通过基于所述不平衡阈值和预设的基础阈值，确定所述第一天线与所述其他天线的辐射性能差异阈值；在所述其他天线中存在至少一个第二天线的情况下，将所述第一天线切换至任一个所述第二天线进行通信，所述第二天线的接收信号强度与所述第一天线的接收信号强度的第一差值大于所述辐射性能差异阈值。如此，可以将当前通信的天线切换至接收信号强度比较好的第二天线，以保证电子设备始终在比较好的接收信号强度下进行通信。
可选的，在所述M个天线中存在至少一个第二天线的情况下，将所述第一天线切换至任一个所述第二天线进行通信，包括：
在所述其他天线中存在至少一个第二天线的情况下，确定第一目标天线，所述第一目标天线为所述第一差值最大的所述第二天线；
将所述第一天线切换至所述第一目标天线进行通信。
本实施方式中，天线切换的判决条件可以为：
Thre+Imb<max{RSRP
1-RSRP
0|…|RSRP
i-RSRP
0|…|RSRP
n-RSRP
0}。
其中，Thre为基础阈值，Imb为所述电子设备当前使用场景下对应的不平衡阈值，RSRP
0为第一天线的接收信号强度，RSRP
i为其他天线中第i个天线的接收信号强度，n为其他天线的数量。
也就是说，当其他天线中存在至少一个第二天线的接收信号强度与第一天线的接收信号强度的差值大于基础阈值与不平衡阈值之和时，将至少一个第二天线中接收信号强度与第一天线的接收信号强度的差值最大的第二天线确定为第一目标天线，并从第一天线切换至第一目标天线上进行通信。
本实施方式中，通过在所述其他天线中存在至少一个第二天线的情况下，确定第一目标天线，所述第一目标天线为所述第一差值最大的所述第二天线；将所述第一天线切换至所述第一目标天线进行通信。如此，可以将当前通信的天线切换至接收信号强度最好的第二天线，以保证电子设备始终在最优的接收信号强度的天线上进行通信。
可选的，在所述第一天线为主天线的情况下，所述将所述第一天线切换至任一个所述第二天线进行通信之后，所述方法还包括：
在识别到所述电子设备所处的使用场景不为预设使用场景的情况下，检测所述第一天线的接收信号强度与所述第二天线的接收信号强度的第二差值；
在所述第二差值大于第一预设阈值的情况下，将所述第二天线切换至所述第一天线进行通信，所述第一预设阈值小于所述辐射性能差异阈值。
本实施方式中，主天线通常为电子设备中辐射性能最好的天线，为了保证电子设备可以始终保持在辐射性能最好的天线上进行通信，可以将天线进行回切，即将当前通信的辅天线切换至主天线。
具体的，在识别到所述电子设备所处的使用场景不为预设使用场景的情况下，可以实时、或每隔预设时间周期、或不定时的，对第一天线的接收信号强度和当前通信的第二天线的接收信号强度进行检测，以确定所述第一天线的接收信号强度与所述第二天线的接收信号强度的第二差值。其中，所述预设使用场景可以包括单手握、双手握、头手效应和身体遮挡等，这些使用场景通常会影响天线的辐射性能。
也就是说，当电子设备所处的使用场景不为影响天线辐射性能的使用场景时，在所述第二差值大于第一预设阈值的情况下，可以将所述第二天线切换至所述第一天线进行通信，其中，所述第一预设阈值小于所述辐射性能差异阈值。这样，可以使得当前通信的辅天线尽快回切至主天线，从而保证电子设备始终保持在辐射性能最好的天线上进行通信。
可选的，所述将所述第一天线切换至任一个所述第二天线进行通信之后，所述方法还包括：
在识别到所述电子设备所处的使用场景从所述第一使用场景切换至第二使用场景的情况下，检测第二目标天线的接收信号强度与进行通信的所述第二天线的接收信号强度的第三差值，所述第二目标天线为所述M个天线中除进行通信的所述第二天线之外的其他天线；
在所述第三差值大于第二预设阈值的情况下，将所述第二天线切换至所述第三差值最大的所述第二目标天线进行通信，所述第二预设阈值大于0。
本实施方式中，所述第二使用场景可以为单手握、双手握、头手效应或 身体遮挡等预设使用场景，也可以为其他使用场景，这里不进行具体限定，所述第二使用场景与所述第一使用场景不同。
在识别到所述电子设备所处的使用场景切换时，可以检测其他天线与进行通信的所述第二天线的接收信号强度的差异。在其他天线中存在比第二天线的接收信号强度好的第二目标天线时，可以将第二天线切换至接收信号强度最好的第二目标天线上进行通信。其中，第二预设阈值可以根据实际情况进行设置，为了保证天线切换有意义，可以合理提高第二预设阈值的取值，使得第二目标天线的接收信号强度适当好于或远远好于第二天线。
本实施方式中，在识别到所述电子设备所处的使用场景从所述第一使用场景切换至第二使用场景的情况下，检测第二目标天线的接收信号强度与进行通信的所述第二天线的接收信号强度的第三差值，所述第二目标天线为所述M个天线中除进行通信的所述第二天线之外的其他天线；在所述第三差值大于第二预设阈值的情况下，将所述第二天线切换至所述第三差值最大的所述第二目标天线进行通信，所述第二预设阈值大于0。如此，可以通过多次天线切换，以保证电子设备始终在最优的接收信号强度的天线上进行通信。
可选的，所述步骤101具体包括：
利用所述电子设备中的传感器识别所述电子设备所处的第一使用场景。
本实施方式中，可以利用电子设备中的一个或多个传感器，来识别电子设备所处的使用场景，在利用电子设备的多个传感器来识别电子设备所处的使用场景时，该多个传感器可以为相同的传感器，也可以为不同的传感器，这里不进行具体限定。
该多个传感器可以包括但不限于近距离传感器和红外传感器等，举几个例子来说，针对单手握和双手握的使用场景，可以通过在电子设备的上部分和下部分分别设置一个近距离传感器来进行识别，在设置在下部分的近距离传感器检测到有物体接近的情况下，则可以识别电子设备所处的使用场景为单手握，而在设置在上部分和下部分的近距离传感器均检测到有物体接近的情况下，则可以识别电子设备所处的使用场景为双手握。
针对头手效应的使用场景，可以通过设置在听筒附近的近距离传感器或红外传感器，来检测电子设备与大脑之间的距离，以在大脑靠近电子设备时， 识别电子设备所处的使用场景为头手效应。
针对身体遮挡的使用场景，可以通过近距离传感器和红外传感器，来检测电子设备与身体各个部位之间的距离，在近距离传感器检测到电子设备远离用户手部，且红外传感器检测到电子设备靠近用户身体部位的情况下，识别电子设备所处的使用场景为身体遮挡。
如此，可以利用电子设备中的传感器自动识别所述电子设备所处的使用场景，使得使用场景的识别非常简单。
