具体实施方式
本申请以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括复数表达形式，除非其上下文中明确地有相反指示。还应当理解，本申请中使用的术语“和/或”是指并包含一个或多个所列出项目的任何或所有可能组合。
图1是本申请实施例示例性示出的一种应用场景示意图。
如图1所示，该场景包括电子设备100和路由设备200。其中，电子设备100为具备Wi-Fi功能的设备，也即是说，电子设备100支持无线保真(Wireless Fidelity，WiFi)技术，可以通过WiFi实现无线网络连接，进行网络数据的收发；路由设备200用于提供Wi-Fi热点。
示例性的，路由设备200可以是提供Wi-Fi热点的Wi-Fi路由器，电子设备100为包括Wi-Fi模组(或Wi-Fi芯片)等结构以提供WiFi功能的设备，电子设备可以通过自身的Wi-Fi模组连接路由设备200并通过路由设备200与外部网络进行通信。为方便描述，以下实施例中将Wi-Fi简写为WiFi，如将Wi-Fi芯片或Wi-Fi模组称为WiFi芯片。
示例性的，当电子设备100的WiFi功能设置为“开启”时(即WiFi功能开启中)，电子设备100可以周期性扫描当前环境范围内的WiFi信号，例如，电子设备100可以为用户显示当前检测到的一个或者多个WiFi信号以及对应的信号强度等信息；此外，电子设备100还可以根据预设的WiFi自动接入设置以及保存的成功接入的WiFi账号等实现WiFi自动接入等操作。当电子设备100的WiFi功能设置为“关闭”时(即WiFi功能被关闭)，电子设备100不会扫描当前环境范围内的WiFi信号，节省了设备的电量消耗，从而能够有效节省电子设备100的功耗。
其中，电子设备100从路由设备200接收到的通信消息，可以包括管理帧，例如beacon(信标)帧、须经路由设备200转发的其他连接设备上报的采集数据、以及路由设备200响应所连接电子设备的探测请求等。
可选地，电子设备100还可以包括蜂窝数据模组，进而，电子设备100可以通过自身的蜂窝数据模组与外部网络进行通信。示例性的，蜂窝数据模组可以为图2中的移动通信模块150。需要说明的是，蜂窝数据模组和WiFi芯片可以位于同一个硬件模块(如芯片) 上；也可以均为单独的硬件模块，本申请实施例对此不作限定。
在图1所示的场景中，若电子设备100与路由设备200存在不匹配或者路由设备200本身配置等问题，导会致电子设备100出现WiFi芯片不休眠以及频繁唤醒电子设备100的操作系统等情况发生，从而导致电子设备100耗电严重。
本申请实施例的发明人通过研究发现以下情况会导致电子设备耗电严重，具体如下：
情况1：路由设备发送beacon帧。
周期不准，导致WiFi芯片不休眠或休眠时间短。
在一些实施例中，路由设备可以向电子设备发送管理帧，例如Beacon(信标)帧等。
beacon帧周期不准的原因主要包括：电子设备和路由设备之间的时间戳(timestamp)没有对齐，导致电子设备无法收到beacon帧或者有较多的beacon帧无法接收。
若接收到较少的beacon帧数会导致WiFi芯片工作时间长，导致电子设备耗电严重，例如存在该问题的电子设备在0点到6点的耗电量可为7％到8％之间。
情况2：路由设备发送的beacon帧的数据待传指示信息(traffic indication map，TIM)位错误置位，电子设备误以为无线访问接入点((Wireless Access Point，AP)侧(即路由设备)仍有数据发送，WiFi芯片不休眠。
其中，TIM位指的是设备与AP连接时分配的关联标识(assoction ID)，当路由设备有数据要发给设备时，可以在beacon帧中将该电子设备对应的TIM位置位(如置1)，进而，该电子设备收到beacon帧看到自己对应的TIM置位后，知道路由设备有数据会发给自身，就会唤醒WiFi芯片，等待数据。
当beacon帧中TIM位被错误置位或一直置位(即使没有数据发送也将TIM位都置上)时，会导致WiFi芯片不下电，引起严重功耗问题。目前TIM置位问题是功耗的首要(TOP)问题，具备该问题的电子设备(问题用户)的耗电量取决于错误置位的错误频率，1次/s的错误频率可导致电子设备耗电10％以上，0.5次/s的错误频率可导致电子设备耗电5％-7％。应理解，TIM位被错误置位可能与路由设备厂商的设计等因素有关。
情况3：路由设备配置密钥更新(rekey)过于频繁，频繁唤醒主机(host)，如唤醒中央处理器。
路由设备的广播密钥一般在指定的时间间隔后更新，然后通过广播密钥更新帧(group rekey帧，简称rekey包)将更新的广播密钥发送至电子设备。
但是，若广播密钥的更新间隔设置得非常短，则路由设备会频繁发送rekey包(如每30s更新一次)给电子设备，导致wifi芯片休眠中断被唤醒，导致电子设备耗电严重。
需要说明的是，在本申请的一些实施例中，广播密钥的更新间隔是路由设备的一个可配置项，但是由于用户无感知且较少有用户知道如何重新配置路由设备的该配置项恢复正常，从而导致该问题影响电子设备的功耗。其中，广播密钥的更新间隔设置得非常短可能是由于路由设备不规范或设置失误等原因造成的。
情况4：路由设备频繁踢电子设备，电子设备又重新发起WiFi连接，导致电子设备的功耗异常。
由于路由设备的自身产品设计等原因，路由设备在没有数据流量的时候会把电子设备 (如手机)踢掉，那么电子设备和路由设备会出现断链，有些路由设备一晚上会踢电子设备数百次，也即是频繁断链，电子设备在被踢后又会自动重连，这样往复造成较严重的功耗问题，问题用户(即具备该问题的电子设备)一般耗电15％以上。
情况5：块请求帧(ADDBA request，简称addba req帧)频繁唤醒host。
其中，addba req帧是用来建立块应答机制(Block Ack)的，但是部分路由设备会频繁发送addbareq action帧请求，导致唤醒host，WiFi芯片一直不休眠。应理解，因为这是管理帧，所以WiFi芯片不会进行过滤，导致电子设备一晚耗电10％左右。
情况6：聚合组播包频繁唤醒Host，WiFi芯片不休眠或休眠时间短。
其中，聚合组播包可以为聚合组播包(Aggregation MAC Service Data Unit，AMSDU)，AMSDU组播包是指把多个服务数据单元(MAC Service Data Unit，MSDU)聚合成的数据包。
目前，WiFi芯片侧进行安卓包过滤(Android Packet Filter，APF)时，只能过滤单个组播包或单个广播包；针对聚合帧，WiFi芯片侧只能过滤单个网络缓冲区(Netbuffer，netbuf)的小包聚合帧，且每个子帧的ip地址头都为组播地址或广播地址，而针对多个netbuf的聚合帧(大包聚合，如AMSDU组播包)或聚合帧中存在任何一个子帧的ip地址头为单播地址均不能进行过滤。
该情况下，问题用户会被频繁唤醒，灭屏耗电可达几百毫安时(mAh)，WiFi芯片不休眠或休眠时间短，导致电子设备一晚耗电10％左右。
情况7：APF过滤报文异常，芯片仍被频繁唤醒。
假设芯片侧已开启APF过滤组播包和广播包，若仍有组播包和广播包频繁唤醒WiFi芯片，则为APF过滤报文异常。
有鉴于此，本申请实施例提供了一种降低功耗的方法，可降低WiFi异常导致的功耗严重的问题。
本申请实施例中，电子设备可以在WiFi芯片出现异常时，关闭WiFi功能。该方法可以避免WiFi芯片异常时出现的不休眠或休眠时间短的情况，从而有效降低WiFi异常导致的功耗严重。为方便描述，下文也将关闭WiFi功能称为关闭WiFi。
本申请实施例中，电子设备还可以在处于深度睡眠模式时进行WiFi异常WiFi监控和管理，其中，WiFi监控为识别WiFi芯片是否出现异常，管理包括关闭和开启WiFi功能。该方法可以避免关闭WiFi功能导致影响用户使用体验。
本申请实施例中，电子设备还可以在未进行可感知业务时进行WiFi异常WiFi监控和管理，其中，WiFi监控为识别WiFi芯片是否出现异常，管理包括关闭和开启WiFi功能，可感知业务可以为中断WiFi功能时出现暂停的业务。该方法可以避免关闭WiFi功能导致影响用户使用体验。
本申请实施例中，电子设备包括但不限于手机、平板电脑、桌面型计算机、膝上型计算机、手持计算机、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本等等。电子设备的示例性实施例包括但不限于搭载 Linux或者其它操作系统的便携式电子设备。电子设备也可为其 它便携式电子设备，诸如膝上型计算机(Laptop)等。

Kernel层还可以包括摄像头驱动，音频驱动和传感器驱动等。内核层还可以包括数字信号处理器驱动(未示出)以及图像处理器驱动(未示出)等。其中，摄像头驱动用于驱动摄像头模组中的一个或多个摄像头的图像传感器采集图像以及驱动图像信号处理器对图像进行预处理。数字信号处理器驱动用于驱动数字信号处理器处理图像。图像处理器驱动用于驱动图形处理器处理图像。
该软件架构还可以包括图3中未示出的、硬件抽象层(hardware abstract layer，HAL)，硬件抽象层，是位于应用程序框架层以及内核层之间的接口层，为操作系统提供虚拟硬件平台。
基于上述图1所示的应用场景以及图2和图3介绍的电子设备的软硬件架构，下面通过图4和图5说明深入该架构分别阐述本申请各个实施例提供的降低功耗的方法。
图4示出了本申请实施例提供的一种降低功耗的方法的流程示意图。如图4所示，该方法包括以下部分或全部步骤：
S11：省电精灵进入深度睡眠模式。
在一些实施例中，在执行S11之前，电子设备可以响应于用户操作，启动WiFi功能。例如电子设备的设置应用中包括WiFi开关或电子设备的主界面的下拉任务栏中包括WiFi开关，电子设备响应于作用于该WiFi开关的用户操作，启动WiFi功能，即电子设备可以通过WiFi芯片与路由设备建立连接。
在一些实施例中，省电精灵可以在确定用户处于睡眠状态时，进入深度睡眠模式(也可以称为夜间模式或睡眠模式)。其中，用户可以为电子设备的使用者。
在一种实现中，省电精灵可以根据当前时间、智能设备锁屏时长、智能设备静止时长、周围环境光亮度以及用户历史上睡眠习惯等信息，通过智能夜间模式算法判断用户是否处于睡眠状态；在用户处于睡眠状态时，进入深度睡眠模式。
例如，省电精灵可以通过智能夜间模式算法可以每十分钟会对用户的状态进行一次判断，如果判断用户当前处于睡眠状态，则可以根据用户习惯预测用户的起床时间。如果处于夜间模式下用户突然解锁设备，则智能夜间模式算法可以立刻退出夜间模式。如果处于夜间模式下，用户突然开灯，则智能夜间模式算法可以在下一次判断的时候退出夜间模式。
其中，智能夜间模式算法是对用户历史上睡眠习惯进行学习得到的，该学习包括学习用户过去一段时间内的开始睡眠时间、起床时间、用户处于睡眠时周围环境光亮度分布以及用户不处于睡眠时周围环境光亮度分布。
本申请实施例中，在用户处于睡眠状态时才启动WiFi监控功能，该方法可以避免在用户使用电子设备过程中出现网络中断而影响用户使用，在用户处于睡眠状态时减少WiFi异常带来的功耗过大的问题。
在本申请的另一些实施例中，省电精灵也可以在用户未处于睡眠模式下启动下述步骤以实现对WiFi耗电的管控(也即是步骤S11不是必须执行的步骤)，本申请实施例对应用场景不作限定，上述深度睡眠模式的场景为本本申请实施例提供的较佳的场景示例，不应构成对本申请实施例的限定。
S12：省电精灵判断数据业务开关是否打开。
进而，省电精灵在数据业务数据开关没有打开时，执行步骤S13；在数据业务数据开关打开时，执行步骤S14。
在一些实施例中，省电精灵可以在进入深度睡眠模式时，判断数据业务开关是否为开启状态。其中，数据业务开关用于开启蜂窝数据。例如，该数据业务开关可以为电子设备上的设置应用中的开关，如“移动网络”中的“移动数据”开关。
示例性的，数据业务开关可以如图7B中的用户界面中的移动网络开关721所示。
在本申请的另一些实施例中，省电精灵也可以不判断数据业务开关是否打开(即不执行步骤S12)，直接执行步骤S14。
S13：电子设备结束执行该方法。
在一些实施例中，省电精灵也可以不执行步骤S12和S13，而是直接执行S14，即无论数据业务开关是否打开均进行WiFi的WiFi监控和管理(简称管控)。
需要说明的是，图4所示的实施例中，省电精灵执行上述S12和S13，可以避免在数据业务开关关闭的情况下关闭WiFi导致电子设备没有联网，出现电子设备的时间、位置等需要联网更新的数据无法更新，从而影响用户体验，该方法可以保证电子设备在WiFi管控的过程中至少可以通过蜂窝数据进行联网，不会出现电子设备断网的情况发生，从而保证用户体验效果。
S14：省电精灵通知WiFi FWK启动WiFi监控。
在一些实施例中，省电精灵可以在数据业务数据开关打开时，通知WiFi FWK启动WiFi监控。
S15：WiFi FWK收到省电精灵发送的启动WiFi监控的通知时，启动WiFi监控。
S16：WiFi FWK周期性查询WiFi芯片的芯片状态。
在一些实施例中，WiFi FWK收到省电精灵发送的启动WiFi监控的通知时，周期性查询WiFi芯片的芯片状态。
其中，芯片状态可以包括正常状态和异常状态；本申请实施例对周期时长不做限定，例如，WiFi FWK可以每五分钟查询一次WiFi芯片的芯片状态。
在本申请的另一些实施例中，WiFi FWK也可以在收到省电精灵发送的启动WiFi监控的通知时，仅查询一次。那么，WiFi FWK执行步骤S21和S22时不需要停止WiFi监控；也不需要执行步骤S25和步骤S26。该方法仅在进入深度睡眠模式时对WiFi芯片的芯片状态进行WiFi监控。
需要说明的是，图4所示的实施例中，WiFi FWK是在省电精灵进入深度睡眠模式后周期性对WiFi芯片的芯片状态进行WiFi监控。该方法可以在深度睡眠模式的整个过程中持续对WiFi芯片的芯片状态进行WiFi监控，当WiFi芯片在整个过程中任一时刻出现异常时可以对WiFi进行管理，从而有效的降低电子设备的功耗，避免耗电严重。
S17：WiFi驱动基于路由数据，确定WiFi芯片的芯片状态。
其中，路由数据可以包括单播帧、beacon帧、rekey包、组播包、广播包和addba req帧中的至少一个，还可以包括未示出的其它数据。
关于WiFi驱动确定WiFi芯片的芯片状态的具体过程可以参见图5中的相关内容，此处暂不展开。
S18：WiFi驱动在确定WiFi芯片的芯片状态异常时，通知WiFi FWK。
在一些实施例中，WiFi驱动在确定WiFi芯片的芯片状态异常时，可以向WiFi FWK发送通知消息，该通知消息可以包括指示芯片状态的指示信息，如指示信息为1代表芯片状态异常，指示信息为0代表芯片状态正常。
可选的，WiFi驱动可以在判断WiFi芯片的芯片状态正常时通知WiFi FWK，也可以不通知WiFi FWK，本申请实施例对此不作限定。
可以理解的，由于WiFi芯片在芯片状态正常时不会造成大量耗电，因此，电子设备在WiFi芯片处于正常状态时可以不对WiFi进行管理，那么，在本申请实施例WiFi芯片的芯片状态正常时不通知WiFi FWK，可以减少通知造成的功耗。
S19：WiFi FWK通知省电精灵WiFi芯片的芯片状态异常。
在一些实施例中，WiFi FWK在接收到WiFi驱动发送的指示WiFi芯片的芯片状态异常的通知时，可以向省电精灵发送通知消息，该通知消息可以包括指示芯片状态的指示信息，如指示信息为1代表芯片状态异常，指示信息为0代表芯片状态正常。
S20：省电精灵判断当前是否有可感知业务。
其中，可感知业务可以为用户可感知的业务，也就是说，该业务若暂停会被用户所感知。例如，可感知业务可以包括后台播放、下载和导航等业务。
在一些实施例中，省电精灵在判断当前有可感知业务(即电子设备正在执行可感知业务)时，执行步骤S13，结束执行以下步骤；在判断当前没有可感知业务时，执行以下步骤S21。
示例性的，省电精灵中可以包括异常识别模块，S20具体由异常识别模块执行。例如，在S19中WiFi FWK可以通知省电精灵中的异常识别模块WiFi芯片的芯片状态异常；进而，异常识别模块可以判断当前是否有可感知业务。
本申请实施例中，电子设备在执行可感知业务时，不关闭WiFi可以保证可感知业务不 被中断，可以避免可感知业务中断后影响用户体验。
在本申请的另一些实施例中，WiFi FWK也可以不执行上述S20和S13，直接执行下述步骤S21。
S21：省电精灵通知WiFi FWK关闭WiFi监控和WiFi。
S22：WiFi FWK关闭WiFi，停止WiFi监控。
在一些实施例中，WiFi FWK可以调用WiFi关闭接口以关闭WiFi功能。
本申请实施例中，电子设备在WiFi监控到WiFi出现异常时，将WiFi功能关闭，可以避免WiFi功能造成的功耗过大，耗电严重的问题。
S23：省电精灵退出深度睡眠模式。
在一些实施例中，省电精灵周期性通过智能夜间模式算法判断用户是否处于睡眠状态；在识别到用户不处于睡眠状态时，退出深度睡眠模式。
S24：省电精灵通知WiFi FWK停止WiFi监控。
在一些实施例中，省电精灵退出深度睡眠模式时，通知WiFi FWK停止WiFi监控。
S25：WiFi FWK判断当前是否在执行WiFi监控。
在一些实施例中，WiFi FWK在接收到省电精灵发送的指示停止WiFi监控的通知后，可以判断是否启动过WiFi监控；在WiFi监控启动时，执行步骤S26，在WiFi监控未启动时，执行步骤S13。
S26：WiFi FWK停止WiFi监控。
在一些实施例中，WiFi FWK在判断WiFi监控启动时，停止WiFi监控。
S27：WiFi FWK判断当前WiFi是否被关闭。
在一些实施例中，WiFi FWK可以判断WiFi是否被关闭过(或当前是否处于关闭状态)；在WiFi被关闭时，执行步骤S28，在WiFi未被关闭时，执行步骤S13。
S28：WiFi FWK启动WiFi。
在一些实施例中，WiFi FWK可以执行步骤S27确定WiFi被关闭时，启动WiFi。
本申请实施例中，在用户处于睡眠状态时启动WiFi监控功能，在用户处于非睡眠状态时停止WiFi监控且在WiFi被关闭时开启WiFi，可以避免在用户使用电子设备过程中网络中断的情况发生，该方法可以在用户处于睡眠状态时减少WiFi异常带来的功耗过大的问题。
图5示出了本申请实施例提供的另一种降低功耗的方法的流程示意图。如图5所示，该方法包括以下部分或全部步骤：
S1：电子设备启动WiFi异常的监控。
在一些实施例中，电子设备可以在开启WiFi功能后，启动WiFi异常的监控。
在另一些实施例中，电子设备的省电精灵可以在用户处于睡眠状态时判断数据业务开关是否打开，进而，在数据业务数据开关打开时，通知WiFi FWK启动WiFi监控。
S2：电子设备查询WiFi芯片的芯片状态。
在一些实施例中，WiFi FWK收到省电精灵发送的启动WiFi监控的通知时，启动WiFi监控，即开始周期性向WiFi驱动查询WiFi芯片的芯片状态；WiFi驱动可以通过以下步骤 S3至步骤S10确定WiFi芯片的芯片状态(为图4中的步骤S17的一种具体实现)。
S3：电子设备获取beacon帧的接收率对应的标志(简称第一标志)。
其中，beacon帧是由路由设备发送至电子设备的管理帧；第一标志用于指示beacon帧的接收率是否出现异常，例如，第一标志可以为0，0用于指示beacon帧的接收率正常；第一标志可以为1，1用于指示beacon帧的接收率异常。其中，beacon帧的接收率也可以称为信标帧接收率。
示例性的，电子设备获取beacon帧的接收率对应的标志的具体过程可以参见以下步骤S31至S35。
S31:电子设备判断beacon帧的接收率是否异常。
进而，电子设备在确定beacon帧的接收率异常时，执行步骤S33；在确定beacon帧的接收率正常时，执行步骤S32。
在一些实施例中，电子设备可以将预设时间内实际收到beacon帧数除以应收beacon帧数(也可以称为预设帧数)，得到beacon接收率(也可以称为信标帧接收率)，若计算得到的beacon接收率低于预设接收率，则认为beacon帧的接收率异常。其中，应收beacon帧数可以为预设帧数。
例如，预设时间为5min，预设接收率可以为60％，那么，电子设备可以在启动WiFi监控后，每五分钟计算一次beacon接收率，若计算得到的beacon接收率低于60％，则确定beacon帧的接收率异常。
需要说明的是，若电子设备接收到较少的beacon帧数会导致WiFi芯片工作时间长，导致电子设备耗电严重，例如接收率低于60％的用户可以为称为问题用户，问题用户0-6点的耗电量大概为7％至8％。本申请实施例可以识别出该问题用户，在符合若干条件(如图4所示的数据开关开启和/或没有可感知业务等)的情况下关闭WiFi，可以避免WiFi芯片工作时间长，可以有效减少电子设备的耗电。
S32:电子设备将第一标志置0。
也就是说，电子设备获取的第一标志为0。其中，0用于指示beacon帧的接收率正常。
S33:电子设备判断beacon帧的接收率对应的异常次数(简称第一异常次数)是否大于N1次。进而，电子设备在确定第一异常次数大于N1次时，执行步骤S35；在确定beacon帧的接收率正常时，执行步骤S34。其中，N1为正整数。
在一些实施例中，电子设备可以从存储中获取记录的第一异常次数，在该异常次数加1后得到更新的第一异常次数，将更新后的第一异常次数与N1比较，从而确定beacon帧的接收率对应的异常次数是否大于N1次。
S34:电子设备将记录的第一异常次数加1。
S35:电子设备将第一标志置1。
也就是说，电子设备获取的第一标志为1。其中，1用于指示beacon帧的接收率异常。

其中，TIM位是指路由设备发送至电子设备的beacon帧中该电子设备对应的标志位，该标志位被置位用于指示路由设备在接下来预设时间内将发送数据给该电子设备。第二标志用于指示TIM位错误置位的频率是否出现异常，例如，第二标志可以为0，0用于指示 TIM位错误置位的频率正常，第二标志可以为1，1用于指示TIM位错误置位的频率异常。
其中，若电子设备的beacon帧中TIM位被置位，但等待预设时间(也可以称为第一时间段)没有接收到来自路由设备发送的数据，则认为TIM位错误置位；TIM位错误置位的频率是指预设时间内TIM位错误置位的次数。如第一时间段可以为60ms。
例如，电子设备每间隔1s接收到一个beacon帧，若该beacon帧中TIM位被置位，则电子设备会等待60ms，若60ms内电子设备接收到该路由设备发送的数据，则该beacon没有被错位置位，反之则被错位置位；若电子设备1s中接收到10个beacon帧，10个beacon帧中有8个错误，则电子设备可以确定TIM位错误置位的频率为每秒钟8帧。
需要说明的是，若beacon帧中TIM位被错误置位或一直置位(即使没有数据发送也将TIM位都置上)时，导致WiFi芯片不下电，会引起严重功耗问题。本申请实施例中，电子设备通过获取TIM位错误置位的频率，在该频率过大时关闭WiFi功能，即让WiFi芯片下电，可以避免出现严重功耗，可以有效减少耗电。
示例性的，电子设备获取TIM位错误置位的频率对应的标志的具体过程可以参见以下步骤S41至S45。
S41:电子设备判断TIM位错误置位的频率是否异常。进而，电子设备在确定TIM位错误置位的频率异常时，执行步骤S43；在确定TIM位错误置位的频率正常时，执行步骤S42。
在一些实施例中，电子设备可以计算预设时间内(也可以称为第二时间段)接收到的beacon帧中TIM位错误的频率，若该频率大于预设频率，则确定TIM位错误置位的频率异常，反之为正常。其中，电子设备在接收beacon帧后预设时间内没有接收到数据则确定该beacon帧中TIM位错误。
也就是说，在第二时间段内接收到TIM位错误的信标帧的次数大于第一预设次数时，确定TIM位错误置位的频率异常。
示例性的，如第二时间段可以为1s，第一预设次数为8，则若电子设备可以每秒计算一次TIM位错误置位的频率，假设在1s中接收到10个beacon帧，10个beacon帧中有8个错误，则电子设备可以确定当前出现TIM位错误置位的频率异常。

其中，rekey包是路由设备发送至电子设备的广播密码更新帧；rekey包的发送频率可以是指路由设备配置的rekey包发送频率(即路由设备发送rekey包的频率)，也即是，电子设备接收rekey包的接收频率。需要说明的是，本申请的部分实施例中，由于实际情况等原因导致路由设备发送rekey包的频率不等于电子设备接收rekey包的接收频率，那么，电子设备可以将电子设备接收rekey包的接收频率确定为判断rekey包是否异常的频率。其中，rekey包的发送频率也可以称为广播密钥更新帧的发送频率。
其中，第三标志用于指示rekey包的发送频率是否出现异常，例如，第三标志可以为0，0用于指示rekey包的发送频率正常，第三标志可以为1，1用于指示rekey包的发送频率异常。

进而，电子设备在确定rekey包的发送频率异常时，执行步骤S53；在确定rekey包的发送频率正常时，执行步骤S52。
在一些实施例中，电子设备可以计算rekey包的发送间隔时间，若rekey包的发送间隔时间小于预设时间间隔(如30s)，则确定rekey包的发送频率异常，反之则正常。
在另一些实施例中，当连续N个时间段内每个时间段中广播密钥更新帧的个数均超过第一预设个数时，电子设备确定广播密钥更新帧的发送频率出现异常，N为正整数。
例如N为10，N个时间段中每一个时间段为1分钟，第一预设个数为2，若电子设备可以计算每分钟接收到的rekey包的个数，若连续十分钟内每分钟接收到至少两个rekey包，则确定rekey包的发送频率异常，反之则正常。
需要说明的是，若电子设备频繁接收到路由设备发送的rekey包，即rekey包的发送频率过高，会导致wifi芯片休眠中断被唤醒，导致电子设备耗电严重。本申请实施例中，电子设备通过获取rekey包的发送频率，在该频率过大(即异常)时关闭WiFi功能，可以避免电子设备出现严重功耗的情况，可以有效减少耗电。

需要说明的是，若电子设备频繁接收到路由设备发送的addba req帧，即addba req帧的发送频率过高，会导致WiFi芯片一直不休眠或休眠时间过短，导致电子设备耗电严重。本申请实施例中，电子设备通过获取addba req帧的发送频率，在该频率过大(即异常)时关闭WiFi功能，可以避免电子设备出现严重功耗的情况，可以有效减少耗电。
