背景技术
天线是终端，如智能手机，实现无线通信的必要组成部分，终端可以利用天线来接收基站发射的信号，也可以利用天线将信号发射出去。
然而在实践中发现，终端中一般配置一根天线，这根天线在自由空间中接收信号和发射信号时比较灵敏。但是，当终端贴近人体时，由于人体阻抗的干扰，会导致天线接收信号的灵敏度下降。
发明内容

实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行相关描述，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。
本公开实施例公开了一种终端及其天线切换方法，可以提高天线接收信号的灵敏度。
本公开实施例中，终端可以包括但不限于智能手机、笔记本电脑、个人计算机(Personal Computer，PC)、个人数字助理(Personal Digital Assistant，PDA)、移动互联网设备(Mobile Internet Device，MID)、智能穿戴设备(如智能手表、智能手环)等各类终端。其中，该终端的操作系统可包括但不限于Android操作系统、IOS操作系统、Symbian(塞班)操作系统、Black Berry(黑莓)操作系统、Windows Phone8操作系统等等。
请参见图1，图1是本公开实施例公开的一种终端的天线切换方法的流程示意图。其中，终端配置有第一天线和第二天线，该第一天线适用于在自由空间中接收信号和发射信号，该第二天线适用于在接近人体时接收信号和发射信号，终端默认使用第一天线。
在S110中、终端实时检测终端移动至距离人体为目标距离时的途经轨迹数据。
本公开实施例中，终端在自由空间和接近人体时接收信号的灵敏度是不一样的。在接近人体时，人体对天线的发射功率有吸收作用，导致终端发射功率衰减。终端的天线需要既满足自由空间的指标要求，又要满足接近人体时的指标要求，仅通过单一天线或天线匹配是难以实现两者兼顾的情况的。因此，本公开实施例中，在终端内部配置了第一天线和第二天线，或者在终端内配置了第一天线匹配电路和第二天线匹配电路。可选地，可以为第一天线匹配电路和 第二天线匹配电路设计不同的参数，以使得该第一天线匹配电路适用于在自由空间中接收信号和发射信号，该第二天线匹配电路适用于在接近人体时接收信号和发射信号。其中，该终端默认使用第一天线匹配电路。
本公开实施例中，终端可以实时检测终端移动至距离人体为目标距离时的途经轨迹数据，其中，该目标距离可以为终端内置的距离传感器测量到的实时距离，该途经轨迹数据可以为轨迹传感器(如重力传感器、陀螺仪)实时检测到的途经轨迹数据，该途经轨迹数据用于表征终端移动的轨迹，比如：移动过程中的轨迹(直线，弧线等)、加速度、倾斜角度等。
在S120中、终端判断目标距离是否小于或等于预设距离，若判定目标距离小于或等于预设距离，则执行S130，若判定目标距离大于预设距离，结束本流程。
本公开实施例中，终端可以判断目标距离是否小于或等于预设距离，其中，该预设距离可以为预先在终端上设定的距离，也可以为终端出厂时默认的距离，比如：预设距离为5cm。
本公开实施例中，当终端判断目标距离小于或等于预设距离时，终端可以确定终端接近于人体，当终端判断目标距离大于预设距离时，终端可以确定终端远离人体。
在S130中、终端判断预存储的特征数据集合中是否存在与途经轨迹数据匹配的特征数据，若判定预存储的特征数据集合中存在有与途经轨迹数据匹配的特征数据，则执行S140，若判断预存储的特征数据集合中未存在与途经轨迹数据匹配的特征数据，结束本流程。
本公开实施例中，当终端判断目标距离小于或等于预设距离时，终端可以确定终端接近于人体。由于终端接近人体的位置可以有多种可能，比如：接近耳朵、接近胸部、接近头部等等，因此，终端需要继续判断预存储的特征数据集合中是否存在与途经轨迹数据匹配的特征数据，以确定终端移动到接近人体的位置以及移动轨迹是否符合预先设计的。其中，该特征数据集合包括预先学习的终端移动至人体局部位置的途经轨迹的特征数据，该人体局部位置可以包括但不限于为耳朵、胸部、头部等等。
示例性地，该预先学习的终端移动至人体局部位置的途经轨迹可以为终端接到来电时，移动至人耳的途经轨迹；或者，终端收听广播时，移动至胸前的途经轨迹。
本公开实施例中，对于同一个用户来说，在某些特定的场合下(比如接听电话)，用户将终端移动至人体局部位置的途经轨迹一般是固定的，因此，终端可以预先学习终端移动至人体局部位置的途经轨迹的特征数据。终端可以通过用户手动学习的方式来学习终端移动至人体局部位置的途经轨迹的特征数据，此外，终端还可以通过智能学习的方式来学习终端移动至人体局部位置的途经轨迹的特征数据。
作为一种可选的实施方式，当终端判断预存储的特征数据集合中不存在与途经轨迹数据匹配的特征数据时，终端可以继续判断终端是否正在接收信号(比如接听来电、收听广播)，若判断终端正在接收信号，则执行S140，若判断终端未接收信号，结束本流程。
示例性地，假设终端被用户装在口袋里，用户习惯于通过耳机等方式来接听信号，终端可能就没有发生移动，终端判断预存储的特征数据集合中就不存在与途经轨迹数据匹配的特征数据，此时，若终端判断当前正在接收来电或者收听广播，为了提高天线接收信号的灵敏度，终端可以将当前默认使用的第一天线切换到第二天线。
在S140中、将第一天线切换到第二天线。
本公开实施例中，当终端判断预存储的特征数据集合中存在与途经轨迹数据匹配的特征数据时，表明终端当前的移动轨迹与预设的移动轨迹一致，此时，终端可以将当前默认使用的第一天线切换到第二天线。
在图1所描述的方法流程中，终端可以检测终端移动至距离人体为目标距离时的途经轨迹数据，并判断目标距离是否小于或等于预设距离，若是，则继续判断预存储的特征数据集合中是否存在与途经轨迹数据匹配的特征数据，若存在，则将第一天线切换到第二天线。
可见，通过本公开实施例，在判断终端接近人体后，又判断终端的运行轨迹数据为预存储的特征数据集合中的特征数据时，终端可以初步确定用户可能 通过将终端贴近该人体局部位置的方式来收听信号，此时，终端将默认使用的第一天线切换到适用于在接近人体时使用的第二天线，以提高天线接收信号的灵敏度。
请参见图2，图2是本公开实施例公开的一种终端的天线切换方法的流程示意图。其中，终端配置有第一天线和第二天线，该第一天线适用于在自由空间中接收信号和发射信号，该第二天线适用于在接近人体时接收信号和发射信号，终端默认使用第一天线。
在S210中、终端学习终端移动至人体局部位置的途经轨迹的特征数据。
本公开实施例中，终端可以以用户手动学习的方式来学习终端移动至人体局部位置的途经轨迹的特征数据。
示例性地，用户可以先将终端水平放置，并开启重力传感器和陀螺仪来检测终端的实时状态，并记录实时特征数据。然后，用户移动终端至人体局部位置(比如耳朵，头部)，在终端维持在人体局部位置，处于稳定状态时，结束实时特征数据的记录。此时，用户可以查看当前终端上显示的信号强度。若当前显示的信号强度较强，用户可以选择把记录的特征数据保存下来。其中，终端显示的信号强度可以以格数的形式来显示，比如信号强度显示格数总共有5格，当有3格满时可以认为当前信号强度较强，或者，终端显示的信号强度可以以百分比的形式来显示，比如60％。
在S220中、终端将学习的特征数据存储至特征数据集合中。
本公开实施例中，终端学习到终端移动至人体局部位置的途经轨迹的特征数据之后，终端可以将学习的特征数据存储至特征数据集合中。
在S230中、终端检测终端移动至距离人体为目标距离时的途经轨迹数据。
在S240中、终端判断目标距离是否小于或等于预设距离，若判断目标距离小于或等于预设距离，执行步骤S205，若判断目标距离大于预设距离，结束本流程。
在S250中、终端判断预存储的特征数据集合中是否存在与途经轨迹数据匹配的特征数据，若判断预存储的特征数据集合中存在与途经轨迹数据匹配的特 征数据，执行步骤S260，若判断预存储的特征数据集合中未存在与途经轨迹数据匹配的特征数据，结束本流程。
在S260中、终端读取第一天线接收到的目标信号强度值。
本公开实施例中，终端判断预存储的特征数据集合中存在与途经轨迹数据匹配的特征数据之后，终端可以读取当前默认使用的第一天线接收到的目标信号强度值。
在S270中、终端判断目标信号强度值是否小于或等于预设信号强度值，若判断目标信号强度值小于或等于预设信号强度值，执行步骤S280，若判断目标信号强度值大于预设信号强度值，结束本流程。
本公开实施例中，终端读取到第一天线接收到的目标信号强度值之后，可以继续判断目标信号强度值是否小于或等于预设信号强度值，若是，表明终端接近人体后，第一天线接收到的目标信号受到了人体的影响，终端可以将当前默认使用的第一天线切换到第二天线，若否，表明终端接近人体后，第一天线接收到的目标信号没有受到人体的影响，或者，人体影响的程度不大，此时，终端可以不进行天线的切换操作。
在S280中、终端将第一天线切换到第二天线。
在S290中、当判断终端与人体的目标距离大于预设距离时，终端将第二天线切换到第一天线。
本公开实施例中，在终端将第一天线切换到第二天线之后，当检测到终端与人体的目标距离大于预设距离时，终端可以将第二天线切换到第一天线。
本公开实施例中，当检测到终端与人体的目标距离大于预设距离时，此时，终端处于自由空间，如果终端不将第二天线切换到第一天线的话，由于第二天线的匹配电路是针对接近人体来设计的，当第二天线在自由空间中接收信号和发射信号时，将会导致终端的功耗增大。在自由空间中，终端将第二天线切换到第一天线时，由于第一天线的匹配电路是针对自由空间来设计的，因此，第一天线在自由空间中接收信号和发射信号就可以减小终端的功耗。
在图2所描述的方法流程中，终端可以预先通过用户手动学习的方式来生成特征数据集合，即：终端可以学习终端移动至人体局部位置的途经轨迹的特 征数据，并将学习的特征数据存储至特征数据集合中。可选地，当终端同时满足以下条件时，将第一天线切换至第二天线：
当终端检测终端移动至距离人体为目标距离时的途经轨迹数据，判断目标距离小于或等于预设距离；
判断预存储的特征数据集合中存在与途经轨迹数据匹配的特征数据；以及
读取到的第一天线接收到的目标信号强度值小于或等于预设信号强度值。
此外，当判断终端与人体的目标距离大于预设距离时，终端可以将第二天线切换到第一天线。
可见，通过本公开实施例，终端可以实时根据终端与人体的距离、终端的运行轨迹以及终端当前信号强度来确定是否对当前正在使用的天线进行切换，从而可以提高天线接收信号的灵敏度，同时，减小终端的功耗。
请参见图3，图3是本公开实施例公开的一种终端的天线切换方法的流程示意图。其中，终端配置有第一天线和第二天线，该第一天线适用于在自由空间中接收信号和发射信号，该第二天线适用于在接近人体时接收信号和发射信号，终端默认使用第一天线。
在S301中、当检测到来电时，终端读取第一天线接收到的初始信号强度值。
本公开实施例中，终端可以通过智能学习的方式来学习终端移动至人体局部位置的途经轨迹的特征数据。可选地，终端可以在检测到来电时，读取第一天线接收到的初始信号强度值。
在S302中、终端学习终端移动至人体局部位置的途经轨迹的特征数据，并在终端移动至人体局部位置时，将第一天线切换到第二天线。
在S303中、终端判断第二天线接收到的信号强度值是否大于初始信号强度值，若判断第二天线接收到的信号强度值大于初始信号强度值，执行S304，若判断第二天线接收到的信号强度值小于或等于初始信号强度值，返回继续执行S303。
本公开实施例中，终端读取到第一天线接收到的初始信号强度值，并在将第一天线切换到第二天线，读取到第二天线接收到的信号强度值之后，终端可 以判断第二天线接收到的信号强度值是否大于初始信号强度值，若是，表明切换到第二天线后，天线接收的信号强度较强，终端可以执行S304，若否，表明切换到第二天线后，天线当前接收的信号强度较弱，由于终端读取的第二天线接收到的信号强度值为实时变化的数值，因此，终端可以返回继续执行S303。
在S304中、终端将学习的特征数据存储至特征数据集合中。
在S305中、当判断终端与人体的目标距离大于预设距离时，终端将第二天线切换到第一天线。
在S306中、终端检测终端移动至距离人体为目标距离时的途经轨迹数据。
在S307中、终端判断目标距离是否小于或等于预设距离，若判断目标距离小于或等于预设距离，执行S308，若判断目标距离大于预设距离，结束本流程。
在S308中、终端判断预存储的特征数据集合中是否存在与途经轨迹数据匹配的特征数据，若判断预存储的特征数据集合中存在与途经轨迹数据匹配的特征数据，执行S309，若判断预存储的特征数据集合中未存在与途经轨迹数据匹配的特征数据，结束流程。
在S309中、终端读取第一天线接收到的目标信号强度值。
在S310中、终端判断目标信号强度值是否小于或等于预设信号强度值，若判断目标信号强度值小于或等于预设信号强度值，执行S311，若判断目标信号强度值大于预设信号强度值，结束流程。
在S311中、终端将第一天线切换到第二天线。
在S312中、当判断终端与人体的目标距离大于预设距离时，终端将第二天线切换到第一天线。
在图3所描述的方法流程中，终端可以预先通过智能学习的方式来生成特征数据集合，即：当检测到来电时，终端可以读取第一天线接收到的初始信号强度值，并当检测到终端与人体局部位置的目标距离小于或等于预设距离时，将第一天线切换到第二天线，并读取第二天线接收到的信号强度值，当判断信号强度值大于初始信号强度值时，学习终端移动至人体局部位置的途经轨迹的特征数据，并将学习的特征数据存储至特征数据集合中。可选地，当终端同时满足以下条件时，将第一天线切换到第二天线：
当终端检测终端移动至距离人体为目标距离时的途经轨迹数据，判断目标距离小于或等于预设距离；
判断预存储的特征数据集合中存在与途经轨迹数据匹配的特征数据；以及
读取到的第一天线接收到的目标信号强度值小于或等于预设信号强度值。
此外，当检测到终端与人体的目标距离大于预设距离时，终端可以将第二天线切换到第一天线。
可见，通过本公开实施例，终端可以实时根据终端与人体的距离、终端的运行轨迹以及终端当前的信号强度来确定是否对当前正在使用的天线进行切换，从而可以提高天线接收信号的灵敏度，同时，减小终端的功耗。

第二处理器部件430，还设置为在轨迹传感器部件410检测终端移动至距离人体为目标距离时的途经轨迹数据之前，学习终端移动至人体局部位置的途经轨迹的特征数据。
本公开实施例中，第二处理器部件430可以以手动学习的方式来学习终端移动至人体局部位置的途经轨迹的特征数据。
示例性地，用户可以先将终端水平放置，并开启重力传感器和陀螺仪来检测终端的实时状态，并记录实时特征数据，用户移动终端至人体局部位置(比如耳朵，头部)，在终端维持在人体局部位置，处于稳定状态时，结束实时特征数据的记录。此时，用户可以查看当前终端上显示的信号强度。若当前显示的信号强度较强，用户可以选择把记录的特征数据保存下来。其中，终端显示的信号强度可以以格数的形式来显示，比如信号强度显示格数总共有5格，当有3格满时可以认为当前信号强度较强，或者，终端显示的信号强度可以以百分比的形式来显示，比如60％。
第一存储器460，设置为将学习的特征数据存储至特征数据集合中。
请参见图7，图7是本公开实施例公开的一种终端的结构示意图，其中，图7所示的终端是在图5所示的终端的基础上优化得到的，与图5所示的终端相比，图7所示的终端除了包括图5所示的终端的所有单元外，还可以包括：第四处理器部件470以及第二存储器480，其中，
第四处理器部件470，设置为在轨迹传感器部件410检测终端移动至距离人体为目标距离时的途经轨迹数据之前，当检测到来电时，读取第一天线接收到的初始信号强度值。
第二处理器部件430，还设置为学习终端移动至人体局部位置的途经轨迹的 特征数据。
天线切换开关440，还设置为在终端移动至人体局部位置时，将第一天线切换到第二天线。
第四处理器部件470，还设置为判断第二天线接收到的信号强度值是否大于初始信号强度值。
第二存储器480，设置为当第四处理器部件470判断第二天线接收到的信号强度值大于初始信号强度值时，将学习的特征数据存储至特征数据集合中。
本公开实施例中，第四处理器部件470在检测到来电时，读取第一天线接收到的初始信号强度值之后，上述第二处理器部件430可以通过智能学习的方式来学习终端移动至人体局部位置的途经轨迹的特征数据。天线切换开关440可以在终端移动至人体局部位置时，将第一天线切换到第二天线，第四处理器部件470判断第二天线接收到的信号强度值是否大于初始信号强度值，若是，表明天线切换开关440切换到第二天线后，天线接收的信号强度较强，第二存储器480可以将学习的特征数据存储至特征数据集合中，若否，表明天线切换开关440切换到第二天线后，天线当前接收的信号强度较弱，由于第四处理器部件470读取的第二天线接收到的信号强度值为实时变化的数值，因此，第四处理器部件470可以继续判断第二天线接收到的信号强度值是否大于初始信号强度值。
天线切换开关440，还设置为当第一处理器部件420判断终端与人体的目标距离大于预设距离时，将第二天线切换到第一天线。
需要说明的是，上述第二处理器部件430可以包括多个子处理器或多个子控制器，该第二处理器部件430中的一个子处理器或子控制器设置为判断预存储的特征数据集合中是否存在与途经轨迹数据匹配的特征数据，该第二处理器部件430中的另外一个子处理器或子控制器用于学习终端移动至人体局部位置的途经轨迹的特征数据。
第四处理器部件470可以包括多个子处理器或多个子控制器，该第四处理器部件470中的一个子处理器或子控制器设置为当检测到来电时，读取第一天线接收到的初始信号强度值，该第四处理器部件470中的另外一个子处理器或 子控制器设置为判断第二天线接收到的信号强度值是否大于初始信号强度值。
在图4-图7所示的终端400中，终端配置有第一天线和第二天线，该第一天线适用于在自由空间中接收信号和发射信号，该第二天线适用于在接近人体时接收信号和发射信号，该终端默认使用第一天线。轨迹传感器部件410可以检测终端移动至距离人体为目标距离时的途经轨迹数据，第一处理器部件420判断目标距离是否小于或等于预设距离，若是，则第二处理器部件430判断预存储的特征数据集合中是否存在与途经轨迹数据匹配的特征数据，若存在，则天线切换开关440将第一天线切换到第二天线。
可见，通过本公开实施例，在第一处理器部件420判断终端接近人体后，第二处理器部件430又判断终端的运行轨迹数据为预存储的特征数据集合中的特征数据时，终端可以初步确定用户可能通过将终端贴近该人体局部位置的方式来收听信号，此时，天线切换开关440将默认使用的第一天线切换到适用于在接近人体时的第二天线后，就可以提高天线接收信号的灵敏度。

工业实用性
本公开实施例在判断终端接近人体后，又判断终端的运行轨迹数据为预存储的特征数据集合中的特征数据时，可以初步确定该终端处于与人体近距离接触使用状态。此时，将默认使用的第一天线切换到适用于在接近人体时的第二天线，以提高天线接收信号的灵敏度。
