具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域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，都属于本申请保护的范围。
移动终端的天线通常是一种驻波天线，天线的阻抗不匹配，将会导致大量的信号反射，使天线的辐射效率降低，同时，还会影响天线在宽频带内的增益，降低天线的性能，影响移动终端的通信效果。
移动终端中的天线系统，通常可以通过可变电容实现天线工作的频率调谐，当天线的阻抗发生变化时，可以对应调节可变电容和开关的通断，实现天线的阻抗匹配。但是，对于不同使用场景下，现有技术中的天线系统无法对天线的阻抗变化进行检测，使得当移动终端的使用场景发生变化时，天线系统无法根据使用场景的变化及时进行自适应调整，从而影响了移动终端的通信质量，降低了用户的体验度。
基于此，本申请实施例提供了一种智能调谐天线的方法、装置和移动终端，以对移动终端的天线性能进行优化。
为便于对本实施例进行理解，首先对本申请实施例所公开的一种智能调谐天线的方法进行详细介绍。
图1示出了一种天线系统的拓扑图，其中，本申请实施例所述的移动终端配置有该天线系统，可以对天线性能进行调谐。通常，可以通过天线调谐器进行天线匹配调谐，或者通过天线开关进行天线孔径调谐，因此，本申请实施例中，通过一个或多个接地开关和可变电容的配合来改变天线的电长度，以实现所需的工作频段谐 振。图1所示的天线系统的拓扑图中，包括天线，以及接地开关K1和K2，C为可变电容，具体实现时，图1所示的天线部分为实际天线结构，该天线可以通过一个或多个接地开关以及可变电容的配合，改变天线的电长度，实现所需要的工作频段谐振。其中，图1中虚线表示该开关可以有或者无，当然上述接地开关的数量，以及可变电容的变化范围，可以根据实际使用情况进行设置，优选接地开关的数量为2或3个，以在保证天线性能的基础上，尽量少用接地开关，减少硬件开支和硬件占用的空间。
基于上述天线系统的拓扑图，图2示出了一种智能调谐天线的方法的流程图，如图2所示，该方法应用于移动终端，包括以下步骤：
步骤S202，检测移动终端的天线信号的电性特征；天线信号包括发往天线侧的发射信号和/或来自天线侧的反射信号；
在实际使用时，发往天线侧的发射信号是指由射频前端发射并传输至天线侧的信号，来自天线侧的反射信号是指上述传输至天线侧的信号经天线端反射回来的信号，在检测电性特征时，可以单独对这两种信号进行检测，也可以同时对两种信号进行检测，其检测过程，可以通过耦合器实现，通过对发往天线侧的发射信号和/或来自天线侧的反射信号进行耦合，可以计算出天线信号的电性特征，因此，上述步骤S202的检测过程可以包括：如果移动终端的天线耦合器感测到天线信号，根据天线信号的功率计算天线信号的电性特征，其中，电性特征包括阻抗特征，如，天线的发射/接收功率、天线的电压驻波比、天线的总效率中的一个或组合特性；上述天线耦合器可以是双向耦合器。
步骤S204，根据电性特征识别移动终端当前所处的天线场景；
其中，天线场景包括以下至少之一：外物靠近天线场景、USB口连接外设场景、耳机连接场景；
通常不同场景下，天线阻抗会发生变化，导致天线信号的电性 特征也随之变化，并且，不同场景下，其电性特征的变化范围也不相同，因此，可以根据电性特征识别移动终端当前所处的天线场景。
步骤S206，根据识别出的天线场景查找预存的天线调谐策略；其中，天线调谐策略包括：场景标识和调谐指示；
步骤S208，按照查找到的调谐指示进行天线调谐操作，以优化移动终端的天线性能。
本申请实施例提供的一种智能调谐天线的方法、装置和移动终端，能够检测移动终端的天线信号的电性特征，并根据电性特征识别移动终端当前所处的天线场景，进而查找天线调谐策略，以优化移动终端的天线性能，使天线性能达到最优状态，进而改善用户使用移动终端的通信体验，提高了用户的体验度。
通常，上述天线调谐策略为移动终端出厂前预置的；和/或，天线调谐策略为移动终端从云服务器获取的。例如，对于USB口连接外设场景，或者耳机连接场景，移动终端可以通过检测对应接口的电平信号来识别场景，因此，对于这些场景下的天线调谐策略可以在移动终端出厂前预置。而对于外物靠近天线场景，由于不同靠近情况天线的电性特征不同，如液体靠近、金属材质靠近或者人体靠近时，其电性特征均不相同，因此，可以通过后期机器学习的方式，从云端服务器获得。
具体实现时，机器学习的过程可以在移动终端上进行，移动终端可以将学习的数据发送至云端服务器，由云端服务器进行大数据的统计和分析处理，进而生成天线调谐策略。基于此，在图2所示方法的基础上，本申请实施例还提供了另一种智能调谐天线的方法的流程图，包括以下步骤：
步骤S302，如果移动终端开启场景学习模式，记录当前场景下检测到的天线信号的电性特征；
具体地，在移动终端的功能菜单中可以配置场景学习模式控件，其中，场景学习模式控件包括预先设置的场景标识和场景操作 提示信息；用户在使用移动终端进行场景学习时，可以选择相应的场景标识，来对对应的场景进行学习，如果场景标识被选中，移动终端可以开启场景标识对应的场景学习模式。
用户还可以预先设置一个学习周期，当移动终端的运行时间达到一个学习周期的时长时，移动终端可以提醒用户开启场景学习模式，进行指定场景的学习。
以上述天线场景为外物靠近天线场景为例进行说明，移动终端开启场景学习模式后，用户可以通过移动终端的人机交互界面显示当前可进行学习的天线场景，用户选择外物靠近天线场景后，移动终端可以继续提示靠近的方式，如手握天线位置，或者手掌贴近天线位置等，此时，天线系统的天线阻抗就会发生变化，移动终端检测到的天线信号的电性特征也随之变化，移动终端可以继续记录并保存该电性特征的变化特征。
为了增加场景学习模式的普遍适用性，在实际学习过程中，移动终端可以对当前场景进行多次学习，采用统计的方式统计并记录当前场景下检测到的天线信号的电性特征。
对于上述多种天线场景，如液体靠近、金属材质靠近等，可以采用遍历切换的方式，学习不同场景下的电性特征，并存储到移动终端的指定寄存器中，以便于生成场景学习数据。
步骤S304，生成场景学习数据，,场景学习数据包括：移动终端的类型标识、当前场景的场景标识和电性特征；
步骤S306，发送场景学习数据至移动终端的云服务器，以使云服务器根据接收到的场景学习数据进行大数据分析，生成与类型标识对应的天线调谐策略。
具体实现时，移动终端可以在用户的操作下，向云服务器发送天线调谐策略的更新请求，此时，云服务器可以将最新生成的天线调谐策略数据包发送至移动终端，使移动终端进行更新；云服务器还可以定期向移动终端发送天线调谐策略的更新提示，以提示用户进行下载和更新，用户可以根据实际使用情况选择是否对天线调谐 策略进行更新等，以便于移动终端在非场景学习模式下，再次遇到该天线场景时，可以快速查找到对应的天线调谐策略，优化天线的天线性能。
当移动终端存储有上述天线调谐策略后，可以继续按照步骤S308～步骤S316的过程对天线进行调谐。
步骤S308，检测移动终端的天线信号的电性特征；天线信号包括发往天线侧的发射信号和/或来自天线侧的反射信号；
步骤S310，根据电性特征识别移动终端当前所处的天线场景；
步骤S312，根据识别出的天线场景查找预存的天线调谐策略；其中，天线调谐策略包括：场景标识和调谐指示；
此时，天线调谐策略可以为移动终端出厂前预置的；和/或，经过步骤S302～步骤S306的过程从云服务器获取的。
具体实现时，移动终端的天线调谐电路可以包括：分别与天线本体连接的天线调谐器和天线开关；天线调谐器包括可变电容；天线开关包括开关和电感串联的电路；因此，按照步骤S312查找到的调谐指示进行天线调谐操作的步骤，包括步骤S314和步骤S316的过程。
步骤S314，从查找到的调谐指示中获取天线调谐器的电容值和天线开关的开关标识；
步骤S316，根据电容值调节天线调谐器的可变电容，以及根据开关标识控制天线开关中各个开关的开关状态。
为了便于对上述智能调谐天线的方法进行理解，图4示出了一种天线系统的结构框图，以及，图5示出了一种天线系统的信号走向示意图。移动终端可以通过上述智能调谐天线的方法对图4或图5所示的天线系统进行调谐，具体地，图4包括天线、可变电容、天线开关、天线耦合器和数字处理单元，为了便于说明，前述天线调谐器仅仅示出了可变电容部分。图5所示的天线耦合器为双向耦合器，该双向耦合器可以对发往天线侧的发射信号进行耦合，以及 对来自天线侧的反射信号进行耦合，其中，图5所示的虚线箭头(1)所示的走向为双向耦合器对发往天线侧的发射信号进行耦合的过程，虚线箭头(2)所示的走向为双向耦合器对来自天线侧的反射信号进行耦合的过程，双向耦合器生成耦合信号后可以将耦合信号发送至数字处理单元。
具体地，数字处理单元可以包括数字处理器，模数转换器和射频前端，其中，数字处理单元为基带数字处理单元，数字处理器可以采用高速并行的DSP芯片；双向耦合器可以根据实际使用需求选择高精度的双向耦合器，从而可以实时感测到天线信号的阻抗变化，以及不同电容值和天线开关组合下的阻抗情况。
基于图4和图5，上述智能调谐天线的过程包括：(1)天线耦合器感测移动终端的天线信号，对天线信号进行耦合，生成耦合信号，并发送至DSP芯片(数字处理器)，DSP芯片可以根据耦合信号计算出当前天线信号的阻抗变化，识别移动终端当前所处的天线场景，并获知当前可变电容的电容值与天线开关中各个开关的开关状态，快速查找调谐指示，以获知可变电容的调节值和天线开关闭合与否的信息，对可变电容的电容值和天线开关的开关状态进行调整，达到阻抗匹配的状态，以优化天线的天线性能。
上述通过双向耦合器进行双向耦合的方式，可以缓解不同天线场景对天线信号的影响，同时，移动终端还可以通过学习的方式针对不同天线场景配置可变电容的电容值和天线开关的开关状态，生成天线调谐策略，并存储电性特征与天线调谐策略的对应关系，使得再次出现上述电性特征时，直接通过对应关系查找调节信号，以优化天线性能。
在上述方法的基础上，本申请实施例还提供了一种智能调谐天线的装置，该装置应用于移动终端，图6所示的一种智能调谐天线的装置的结构示意图，该装置包括：
电性特征检测模块60，用于检测移动终端的天线信号的电性特征；天线信号包括发往天线侧的发射信号和/或来自天线侧的反 射信号；
场景识别模块62，用于根据电性特征识别移动终端当前所处的天线场景，天线场景包括以下至少之一：外物靠近天线场景、USB口连接外设场景、耳机连接场景；
策略查找模块64，用于根据识别出的天线场景查找预存的天线调谐策略；其中，天线调谐策略包括：场景标识和调谐指示；
调谐模块66，用于按照查找到的调谐指示进行天线调谐操作，以优化移动终端的天线性能。
图7示出了另一种智能调谐天线的装置的结构示意图，除图6所示的结构外，上述装置还包括：
场景学习模块68，用于当移动终端开启场景学习模式时，记录当前场景下检测到的天线信号的电性特征；生成场景学习数据，场景学习数据包括：移动终端的类型标识、当前场景的场景标识和电性特征；
数据发送模块70，用于发送场景学习数据至移动终端的云服务器，以使云服务器根据接收到的场景学习数据进行大数据分析，生成与类型标识对应的天线调谐策略。
具体实现时，上述移动终端的天线调谐电路包括：分别与天线本体连接的天线调谐器和天线开关；天线调谐器包括可变电容；天线开关包括开关和电感串联的电路；
因此，上述调谐模块66用于从查找到的调谐指示中获取天线调谐器的电容值和天线开关的开关标识；根据电容值调节天线调谐器的可变电容，以及根据开关标识控制天线开关中各个开关的开关状态。
具体实现时，上述电性特征检测模块用于当移动终端的天线耦合器感测到天线信号时，根据天线信号的功率计算天线信号的电性特征，其中，电性特征包括阻抗特征。
