技术领域
本发明涉及移动通信系统中射频调谐技术，尤其涉及一种射频调谐方法、终端、射频前端器件及计算机可读存储介质。
背景技术
目前，终端能够支持的频段越来越多，从而使得终端的功能不断完善与增加。然而，现有终端中所使用的射频前端器件所支持的工作频段是固定的，也就是说终端在最初的研发设计时某个射频通路设计为支持某个频段，则在实际工作中只能支持该频段，不可复用工作在除此频段以外的频段。例如，以频分双工(FDD)制式上所用的双工器为例，双工器的一个通路只能支持一个频段，那么在4G中，如果希望支持的FDD频段数目大于一个的话，那么每个频段都需要有一个对应的双工器。因此，终端所支持的频段的增加，会要求终端自身通过增加器件实现能够在不同制式和频段下正常工作，即对于不同制式和频段，在终端的具体电路上需要有与之相对应的射频通路。但是，在要求终端满足小型化、待机时间长等前提下，印刷电路板上可供射频前端器件使用的面积有限，器件的增多不仅将增大对印刷电路板进行布线与器件布局等方面的设计复杂度，而且还会提高成本。

实施例一
图1为本发明实施例射频调谐方法的实现流程示意图，如图1所示，该方法包括：
步骤101：获取用于控制射频前端器件工作于第一工作频段的第一控制指令；
具体地，终端开机后自动启动扫频操作、终端周期性自动启动扫频操作或终端的用户通过设置的操作界面启动扫频操作后，若所述终端检测到扫频的触发指令，则根据协议栈中对不同工作频段的使用优先级别的排序，获取第一使用优先级别的第一工作频段所对应的第一控制指令，所述第一控制指令用于控制所述射频前端器件工作于所述第一工作频段。
这里，所述射频前端器件可设置于所述终端上；所述射频前端器件包括射频天线、功率放大器、声表面滤波器、双工器、天线开关、射频收发芯片内部的放大器等；所述不同工作频段可以概括为低频频段、中频频段、高频频段，其中，所述每个低频频段、中频频段、高频频段中都包含有多个具体的工作频段；所述第一工作频段并非用于限定为一个具体的频段，所述第一工作频段用于代指任意一个具体的频段。
这里，在用户对终端或射频前端器件的预先调试过程中，可根据射频 前端器件工作于不同工作频段时所对应的调试结果与工作频段之间的关系，设置一个控制指令集，所述控制指令集包含有使射频前端器件工作于不同工作频段所需要的控制指令，例如：将射频前端器件在1920MHz～1980MHz频段所对应的控制指令作用于该射频前端器件，则可使该射频前端器件工作于该频段；所述控制指令集可以存储于终端中或外部的存储装置中，当所述控制指令集存储于外部的存储装置时，终端可通过给存储装置发送读取指令的方式从控制指令集中获取射频前端器件的控制指令；此外，可对射频前端器件设置ID标识，并将射频前端器件的ID标识插入至该射频前端器件所对应的控制指令中。

具体地，终端检测所述射频前端器件工作于所述第一工作频段时返回的回波损耗参数是否小于或等于预设阈值，若是，则检测网络侧发送的信号的第一参数是否满足设定的接入条件，若满足，则判定所述工作参数满足预设工作条件，否则判定所述工作参数不满足预设工作条件；当所述工 作参数被判定为满足预设工作条件时，终端向所述射频前端器件发送确认指令，以使所述射频前端器件保持工作于所述第一工作频段。
这里，当射频前端器件接收到步骤102中终端所发送的第一控制指令并根据所述第一控制指令调谐工作于第一工作频段后，所述射频前端器件会产生一个与工作于所述第一工作频段时所对应的回波损耗参数，并将所述回波损耗参数发送给终端。

检测所述射频前端器件工作于所述第二工作频段时的工作参数是否满足预设工作条件，并在满足预设工作条件时使所述射频前端器件工作于所述第二工作频段，不满足预设工作条件时继续获取用于控制所述射频前端器件工作于除第一、第二工作频段以外的工作频段的控制指令，直至检测出工作参数满足预设工作条件的工作频段，或待检测的工作频段检测完毕。
具体地，当终端在步骤103中检测出所述射频前端器件工作于所述第 一工作频段时返回的回波损耗参数大于预设阈值，或者检测出所述射频前端器件工作于所述第一工作频段时返回的回波损耗参数小于或等于预设阈值、且网络侧所发送的信号的第一参数不满足设定的接入条件时，根据协议栈中对不同工作频段的使用优先级别的排序，获取第二使用优先级别的第二工作频段所对应的第二控制指令，所述第二控制指令用于控制所述射频前端器件工作于所述第二工作频段，所述第二工作频段不同于所述第一工作频段；终端将获取的所述用于控制所述射频前端器件工作于第二工作频段的第二控制指令向所述射频前端器件发送，以使所述射频前端器件工作于所述第二工作频段；终端检测所述射频前端器件工作于所述第二工作频段时返回的回波损耗参数是否小于或等于预设阈值，若是，则检测网络侧发送的信号的第一参数是否满足设定的接入条件，若满足，则判定所述工作参数满足预设工作条件，否则判定所述工作参数不满足预设工作条件；当所述工作参数被判定为满足预设工作条件时，终端向所述射频前端器件发送确认指令，以使所述射频前端器件保持工作于所述第二工作频段。
这里，终端可根据获取的第二控制指令中所插入的射频前端器件的ID标识，将所述第二控制指令向该ID标识所对应的射频前端器件发送。
这里，当终端检测出所述射频前端器件返回的回波损耗参数大于预设阈值，或者检测出所述射频前端器件工作于所述第一工作频段时返回的回波损耗参数小于或等于预设阈值、且网络侧所发送的信号的第一参数不满足设定的接入条件时，说明所述射频前端器件工作于所述第一工作频段时无法满足要求，需要重新使所述射频前端器件调谐工作于除第一工作频段以外的工作频段。
这里，当终端检测出所述射频前端器件工作于所述第二工作频段时返回的回波损耗参数大于预设阈值，或者检测出所述射频前端器件工作于所述第二工作频段时返回的回波损耗参数小于或等于预设阈值、且检测到网络侧所发送的信号的第一参数不满足设定的接入条件时，继续从控制指令集中获取用于控制所述射频前端器件工作于除第一、第二工作频段以外的工作频段的控制指令，直至检测出工作参数满足预设工作条件的工作频段，或协议栈中待检测的工作频段检测完毕。
举例说明：当终端检测出射频前端器件工作于所述第二工作频段时返回的回波损耗参数大于预设阈值时，从控制指令集中获取用于控制所述射频前端器件工作于第三工作频段的第三控制指令，以使所述射频前端器件工作于第三工作频段；当终端检测出所述射频前端器件工作于所述第三工作频段时返回的回波损耗参数小于预设阈值时，检测网络侧发送的信号的第一参数是否满足设定的接入条件，若不满足，则从控制指令集中获取用于控制所述射频前端器件工作于第四工作频段的第四控制指令，以使所述射频前端器件工作于第四工作频段；当终端检测出所述射频前端器件工作于所述第第四工作频段时返回的回波损耗参数小于预设阈值时，检测网络侧发送的信号的第一参数是否满足设定的接入条件，若满足，则向所述射频前端器件发送确认指令，以使所述射频前端器件保持工作于所述第四工作频段。在实际应用中，当终端处于移动状态且在连接态执行任务时，终端可以周期性地检测周围小区的信号质量并上报基站，当基站发现相邻小区信号的质量或者信号的强度高于设置的门限值、且当前服务小区信号的质量或者信号的强度低于设置的门限值，基站会让终端切换到相邻小区，终端通过调度射频前端器件执行调谐操作自动适时的执行切换动作，从而维持用户的正常使用。

下面将通过一个具体示例对本发明作进一步地的说明。
图5为本发明实施例终端的组成结构示意图，如图5所示，所述终端包括处理器31、射频前端器件32、存储器33；所述射频前端器件32包括射频天线321、射频前端322、射频收发芯片323。
这里，所述射频天线321、射频前端322、射频收发芯片323的内部包含有耦合器，配置为输出工作在不同工作频段时的回波损耗值；所述射频前端322包括功率放大器、声表面滤波器、双工器等器件。
这里，存储器33中预先存储有射频前端器件32在不同工作频段所对应的控制指令，即射频天线321、射频前端322、射频收发芯片323在不同工作频段所对应的控制指令，所述控制指令是用户在对终端或射频前端器件32进行的调试过程中，根据不同工作频段与调试结果之间的关系所设置的；所述不同工作频段可以概括为低频频段、中频频段、高频频段，所述每个低频频段、中频频段、高频频段中都包含有多个具体的频段；此外，预先为射频前端器件32中的每个器件设置一个ID标识，并将ID标识插入至对应器件的控制指令中，以方便处理器31调用。
