具体实施方式
为了使本公开的目的、技术方案及优点更加清楚明白，下面通过具体实施方式结合附图对本公开实施例作进一步详细说明。此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
实施例一
目前的手机在接入wifi网路时，不管wifi网络的信号质量是好还是差，均是通过同一条wifi信号的传输路径进行传输，在信号好的情况下依然采用信号差的传输路径会让wifi信号的传输功耗显著增加，基于该问题，本实施例提供了一种减少wifi耗电的方法。
参见图1，图1为本实施例提供的一种减少wifi耗电的方法的流程步骤示意图。减少wifi耗电的方法包括以下步骤S101至S103。
S101、获取当前接入的wifi网络的信号参数。
获取信号参数的方法包括但不限于从终端的wifi天线上获取信号参数，通过该信号参数就可以知道终端接入的wifi信号当前的信号质量的情况。
S102、根据信号参数确定wifi信号的目标传输路径，目标传输路径包括：低能耗传输路径或常规传输路径。
本实施中wifi信号的传输路径可以在低能耗传输路径和常规传输路径之间进行切换，低 能耗传输路径是在常规传输路径的基础上进行适当的优化，在wifi信号质量好的情况下，取消了一部分不必要的中间节点，从而降低wifi信号传输过程中的耗电量。
S103、将wifi信号的传输路径切换到目标传输路径。
在另一实施例中，低功耗传输路径包括：信号天线、双工器Dip(Diplexer)和wifi收发芯片；常规传输路径包括：信号天线、双工器Dip、射频前端模块FEM(Front End Module)和wifi收发芯片。
上述的低功耗传输路径与常规传输路径相比，减少了射频前端模块FEM，在信号质量好的情况下可以不再需要射频前端模块FEM对信号进行处理，可以有效地降低wifi信号传输过程中的耗电量，达到降低功耗的目的。
在另一实施例中，根据信号参数确定wifi信号的目标传输路径，包括：当信号参数小于预设信号阈值时，选择常规传输路径传输；当信号参数大于等于预设信号阈值时，选择低功耗传输路径。
本实施例的目的是为了减小wifi耗电，因此预设信号阈值的具体数值可以根据实际情况进行设置，在保证wifi连接的稳定性和不额外增加功耗的情况下设置预设信号阈值的数值即可，本实施例中并不做具体限定。
在另一实施例中，目标传输路径包括：第一目标传输路径和第二目标传输路径；第一目标传输路径和第二目标传输路径同时为低能耗传输路径，或，同时为常规传输路径。
随着无线通信技术的发展，无线信号传输的带宽在快速的增加。为了满足更大的无线带宽，wifi信号的传输路径不再局限于一条，开始出现双MIMO和3MIMO，甚至是4MIMO技术。双MIMO技术就是将wifi信号的传输路径变成两条，这样在进行大量数据传输时可以同时使用两条传输路径来传输信息。因此本实施中的目标传输路径也包括但不限于第一目标传输路径和第二目标传输路径。在终端只接入一个wifi网络的情况下，可以采用第一目标传输路径和第二目标传输路径，第一目标传输路径和第二目标传输路径可以同时为低能耗传输路径，也可以同时为常规传输路径。
在另一实施例中，还包括：获取单位时间的数据吞吐量；当数据吞吐量小于预设吞吐阈值时，将wifi信号的传输路径切换到第一目标传输路径；当数据吞吐量大于等于预设吞吐阈值时，将wifi信号的传输路径切换到第一目标传输路径和第二目标传输路径。
当wifi信号可用的传输路径增加以后，为了确定何时需要增加实际占用的传输路径，可以对数据吞吐量进行统计，当单位时间的数据吞吐量大于等于预设吞吐阈值时可以增加一条传输路径，当小于预设吞吐阈值时可以只占用一条传输路径即可。本实施例中预设吞吐阈值 的实际数值可以根据天线设计指标进行合理设置，本实施例中并不做具体限定。
在另一实施例中，信号参数包括但不限于：工作频段、信道、无线信号强度、上下行通话质量、数据吞吐率和误码率中的至少一种。
本实施例提供了一种减少wifi耗电的方法，该方法包括：获取当前接入的wifi网络的信号参数；根据信号参数确定wifi信号的目标传输路径，目标传输路径包括：低能耗传输路径或常规传输路径；将wifi信号的传输路径切换到目标传输路径。通过获取当前接入的wifi网络的信号参数来确定wifi信号的好坏，从而确定wifi信号需要接入低能耗传输路径还是常规传输路径，再将wifi信号的传输路径切换到对应的目标传输路径上，从而实现了包括但不限于降低终端接入wifi网络时的功耗和发热的技术效果。
实施例二
本实施例提供一种减少wifi耗电的装置，参见图2，图2为本实施例提供的一种减少wifi耗电的装置的结构示意图。其中减少wifi耗电的装置10包括：信号参数获取模块11，用于获取当前接入的wifi网络的信号参数；自适应控制模块12，用于根据信号参数确定wifi信号的目标传输路径，目标传输路径包括：低能耗传输路径或常规传输路径；路径选择模块13，用于将wifi信号的传输路径切换到目标传输路径。
信号参数获取模块获取信号参数的方法包括但不限于从终端的wifi天线上获取信号参数，通过该信号参数就可以知道终端接入的wifi网络当前的信号质量的情况；自适应控制模块在得到信号参数以后确定终端接入的wifi网络当前的信号质量，来确定wifi信号具体采用那条路径进行传输，例如，wifi信号质量好就可以采用低能耗路径进行传输，wifi信号质量差，在传输的过程中就可以对wifi信号进行增强，这就可以采用能够进行信号增强的常规路径进行传输，对信号进行增强会导致能耗的增加。
wifi信号的传输路径可以在低能耗传输路径和常规传输路径之间进行切换，低能耗传输路径是在常规传输路径的基础上进行适当的优化，在wifi信号质量好的情况下，取消了一部分不必要的中间节点，从而降低wifi信号传输过程中的耗电量。
在另一实施例中，低功耗传输路径包括：信号天线、双工器Dip和wifi收发芯片；常规传输路径包括：信号天线、双工器Dip、射频前端模块FEM和wifi收发芯片。
上述的低功耗传输路径与常规传输路径相比，减少了射频前端模块FEM，在信号质量好的情况下可以不再需要射频前端模块FEM对信号进行处理，可以有效地降低wifi信号传输过程中的耗电量，达到降低功耗的目的。
在另一实施例中，减少wifi耗电的装置还包括：数据统计模块，用于获取单位时间的数据吞吐量；目标传输路径包括第一目标传输路径和第二目标传输路径；第一目标传输路径和第二目标传输路径同时为低能耗传输路径，或，同时为常规传输路径。
路径选择模块，还用于当数据吞吐量小于预设吞吐阈值时，将wifi信号的传输路径切换到第一目标传输路径；当数据吞吐量大于等于预设吞吐阈值时，将wifi信号的传输路径切换到第一目标传输路径和第二目标传输路径。
随着无线通信技术的发展，无线信号传输的带宽在快速的增加。为了满足更大的无线带宽，wifi信号的传输路径不再局限于一条，开始出现双MIMO和3MIMO，甚至是4MIMO技术。双MIMO技术就是将wifi信号的传输路径变成两条，这样在进行大量数据传输时可以同时使用两条传输路径来传输信息。因此本实施中的目标传输路径也包括但不限于第一目标传输路径和第二目标传输路径。在终端只接入一个wifi网络的情况下，可以采用第一目标传输路径和第二目标传输路径，第一目标传输路径和第二目标传输路径可以同时为低能耗传输路径，也可以同时为常规传输路径。
当wifi信号可用的传输路径增加以后，为了确定何时需要增加实际占用的传输路径，可以对数据吞吐量进行统计，当单位时间的数据吞吐量大于等于预设吞吐阈值时可以增加一条传输路径，当小于预设吞吐阈值时可以只占用一条传输路径即可。本实施例中预设吞吐阈值的实际数值可以根据天线设计指标进行合理设置，本实施例中并不做具体限定。
可参见图3，图3为本实施例提供的另一种减少wifi耗电的装置的结构示意图。图3的减少wifi耗电的装置中包括了数据统计模块14，此时的目标传输路径就包括了第一目标传输路径和第二目标传输路径；并且第一目标传输路径和第二目标传输路径同时为低能耗传输路径，或，同时为常规传输路径。当减少wifi耗电的装置包括了数据统计模块14以后，路径选择模块13的功能还包括当数据吞吐量小于预设吞吐阈值时，将wifi信号的传输路径切换到第一目标传输路径；当数据吞吐量大于等于预设吞吐阈值时，将wifi信号的传输路径切换到第一目标传输路径和第二目标传输路径。
本实施例提供了一种减少wifi耗电的装置，该装置包括：信号参数获取模块，用于获取当前接入的wifi网络的信号参数；自适应控制模块，用于根据信号参数确定wifi信号的目标传输路径，目标传输路径包括：低能耗传输路径或常规传输路径；路径选择模块，用于将wifi信号的传输路径切换到目标传输路径。通过获取当前接入的wifi网络的信号参数来确定wifi信号的好坏，从而确定wifi信号需要接入低能耗传输路径还是常规传输路径，再将wifi信号的传输路径切换到对应的目标传输路径上，从而实现了包括但不限于降低终端接入wifi网络 时的功耗和发热的技术效果。
实施例三
本实施例给出了一种可实现的减少wifi耗电的装置的实施方式。
可参见图4，图4为本实施提供的一种减少wifi耗电的装置和wifi信号传输路径的结构示意图。
数据统计模块14，用于获取当前5G终端传输数据量的大小。在一些业务场景下数据量比较高，高于某个阈值(比如手游、看视频等刚加载资源的时候)，wifi要切至双通道来满足用户对于高速数据传输的要求。当数据量低于阈值时，则关闭双通道，降低终端功耗。
信号参数获取模块11，用于获取wifi的网络环境(wifi网络的信号参数)。wifi网络的信号参数包括工作频段、信道、无线信号强度、上下行通话质量、数据吞吐率、误码率等参数指标。
信号参数获取模块11的工作过程如下，天线接收来自基站的通讯信号，经过射频前端滤波，信号放大到进入wifi主芯片变频，再传输给基带处理模块，将信号进行模数处理，换算成对应的网络参数，如频段、信道号Arfcn(Absolute Radio Frequency Channel Number)或中心频点，还包括信号质量参数，如信号强度RSSI(Received Signal Strength Indication)、信噪比SNR(Signal Noise Ratio)、信道质量指数CQI(Channel Quality Index)、上行发射功率等，通过这些参数的采集及对比，即可得到不同通道下的网络信号质量差异，来指导路径选择。
自适应控制模块12，该模块与路径选择模块13相连，根据上述数据统计模块14和信号参数获取模块11得到的数据控制wifi主芯片及开关，继而控制通道模式(单双通道)及最优路径的选择。
路径选择模块13，与自适应控制模块12相连,用于根据当前网络情况和传输数据量大小的走线线路进行调整控制。如图4，在4对收发通道加入开关，额外引入了4对不经过FEM的收发通道，总共8对wifi收发通道。针对情况1：数据量低于阈值，且不经过FEM的通道信号质量达标，优先在不经过FEM的路径中选择最优的一条通道，减少了FEM带来的功耗；针对情况2：数据量低于阈值，且不经过FEM的通道信号质量不达标，则在经过FEM的路径中选择最优的一条通道；针对情况3：数据量高于阈值，且不经过FEM的通道信号质量达标，优先在不经过FEM的路径中选择最优的两条通道2T2R；针对情况4：数据量高于阈值，且不经过FEM的通道信号质量不达标，则在经过FEM的路径中选择最优的两条通道2T2R。 在本模块中引入开关是为了收发通道能够跳过FEM，减少FEM引入的功耗。
为了对自适应控制模块12中的参数进行调整，以及提供必要的程序驱动，本公开中自适应控制模块12还包括程序单元15，用于驱动程序的调用，控制wifi信号按照最优路径传输，并针对上述4种情况做出具体程序调度。
本实施例提供的一种优化wifi耗电的装置，在wifi收发芯片与射频FEM间添加开关，开关的作用是当信号强度足够时可以直接绕过FEM，避免了FEM的功耗，当信号较弱时则开关可以切至FEM，通过FEM放大信号；通过传输数据包的大小判断当前用户对于数据传输的要求，进而选择单通道还是双通道传输数据，在数据量不大的情况下选择单通道(天线)，降低手机功耗，反之选择开启双通道；使用信号侦测模块采集各wifi通道的收发信号质量，切换开关的引入又额外增加了4路收发信道，从优选择最佳射频路径。
实施例四：
本实施例还提供了一种计算机可读存储介质，该计算机可读存储介质包括在用于存储信息(诸如计算机可读指令、数据结构、计算机程序模块或其他数据)的任何方法或技术中实施的易失性或非易失性、可移除或不可移除的介质。计算机可读存储介质包括但不限于RAM(Random Access Memory，随机存取存储器)、ROM(Read-Only Memory，只读存储器)、EEPROM(Electrically Erasable Programmable Read Only Memory，带电可擦可编程只读存储器)、闪存或其他存储器技术、CD-ROM(Compact Disc Read-Only Memory，光盘只读存储器)、数字多功能盘(DVD)或其他光盘存储、磁盒、磁带、磁盘存储或其他磁存储装置、或者可以用于存储期望的信息并且可以被计算机访问的任何其他的介质。
本实施例中的计算机可读存储介质可用于存储一个或者多个计算机程序，其存储的一个或者多个计算机程序可被处理器执行，以实现上述的减少wifi耗电的方法的步骤。
