技术领域
本申请涉及终端领域，尤其涉及一种网络加速方法和装置。
背景技术
随着互联网的快速发展，人们在日常生活中越来越离不开互联网。人们经常会利用碎片时间上网，比如在等待/乘坐电梯的碎片时间使用社交短视频类应用观看短视频。
然而，用户在上网过程中进入电梯时，由于电梯对网络信号的屏蔽作用，用户使用的电子设备(例如，手机)的网络信号(蜂窝网络信号或无线保真(wireless-fidelity,Wi-Fi)网络信号)通常会突然变差甚至掉网，从而造成用户上网卡顿，导致用户体验较差。
发明内容
本申请实施例提供一种网络加速方法和装置，能够解决用户进入电梯后上网卡顿的问题。
第一方面，本申请实施例提供一种网络加速方法，应用于电子设备，包括：电子设备运行第一应用；电子设备预测用户是否等待进入目标电梯；若确定用户等待进入目标电梯，电子设备的第一应用进行网络加速处理，网络加速处理包括提前缓存第一应用的运行数据、降低第一应用的帧率、降低第一应用的码率或降低第一应用的分辨率中的至少一种。
基于本申请实施例提供的网络加速方法，在用户等待进入目标电梯(即用户在电梯口附近等待)期间，前台应用(第一应用)可以进行网络加速处理，例如提前缓存应用数据和/或降低分辨率、帧率、码率等处理，避免用户进入电梯后上网卡顿的问题，使得后续用户在电梯内时可以继续查看第一应用的相关内容(例如，继续刷短视频，继续看电影等)。
在一种可能的实现方式中，电子设备存储至少一个电梯对应的地理围栏的围栏数据，围栏数据包括电子设备在电梯附近可连接到的Wi-Fi接入点的地址和可搜索到的Wi-Fi列表信息，Wi-Fi列表信息包括至少一个Wi-Fi接入点的地址；电子设备预测用户是否等待进入目标电梯，包括：从至少一个电梯对应的地理围栏的围栏数据中获取目标围栏数据，目标围栏数据指示的可连接到的Wi-Fi接入点地址与电子设备当前连接的Wi-Fi接入点地址相同；电子设备获取当前第一Wi-Fi列表信息，当前第一Wi-Fi列表信息包括所示电子设备当前可搜索到的Wi-Fi接入点的地址；若当前第一Wi-Fi列表信息与目标围栏数据指示的可搜索到的Wi-Fi列表信息之间相同的Wi-Fi接入点地址的数量满足第一条件，确定用户等待进入目标电梯。即电子设备检查当前连接的 Wi-Fi接入点地址(的BSSID)是否有对应的围栏数据。若连接的Wi-Fi对应的BSSID存在围栏数据(目标围栏数据)，电子设备可以进行Wi-Fi信息扫描得到当前第一Wi-Fi列表信息，将当前第一Wi-Fi列表信息与目标围栏数据指示的可搜索到的Wi-Fi列表信息进行对比。若当前第一Wi-Fi列表信息与目标围栏数据指示的可搜索到的Wi-Fi列表信息之间相同的Wi-Fi接入点地址的数量满足第一条件(例如，相同的Wi-Fi接入点地址的数量大于80％)，即用户在当前位置搜索到的Wi-Fi列表信息与目标电梯对应的Wi-Fi列表信息相似度较大，说明用户已经非常靠近目标电梯，等待进入目标电梯(可以理解的是，在目标电梯附近处才可以搜索到与目标电梯对应的Wi-Fi列表信息相似度较大的Wi-Fi列表信息)。
在一种可能的实现方式中，Wi-Fi列表信息还包括对应Wi-Fi接入点地址的网络信号强度，确定用户等待进入目标电梯之前，还包括：相同的Wi-Fi网络接入点地址中存在的可匹配Wi-Fi网络接入点的数量满足第二条件，可匹配Wi-Fi网络接入点为相同的Wi-Fi网络接入点地址中对应的网络信号强度之差小于第一阈值的Wi-Fi网络接入点。这样，基于相同的Wi-Fi网络接入点地址的数量和网络信号强度之差小于第一阈值的Wi-Fi网络接入点的数量，可以更加准确地判断出用户是否等待进入目标电梯(即用户是否到达电梯口)，减少误差。
在一种可能的实现方式中，第一条件为当前第一Wi-Fi列表信息与目标围栏数据之间相同的Wi-Fi接入点地址的数量超过第二阈值，或者第一条件为当前第一Wi-Fi列表信息与目标围栏数据之间相同的Wi-Fi接入点地址的数量占目标围栏数据中所有Wi-Fi接入点数量的比值超过第三阈值。当前第一Wi-Fi列表信息与目标围栏数据之间相同的Wi-Fi接入点地址的数量越多，表示用户在当前位置搜索到的Wi-Fi列表信息(当前第一Wi-Fi列表信息)与目标电梯对应的Wi-Fi列表信息相似度较大。
在一种可能的实现方式中，第二条件为可匹配Wi-Fi网络接入点的数量超过第四阈值，或者第二条件为可匹配Wi-Fi网络接入点的数量占目标围栏数据中所有Wi-Fi接入点数量的比值超过第五阈值。可匹配Wi-Fi网络接入点的数量越多，用户在当前位置搜索到的Wi-Fi列表信息(当前第一Wi-Fi列表信息)与目标电梯对应的Wi-Fi列表信息相似度越大。

在一种可能的实现方式中，在至少一个围栏数据中获取目标围栏数据之前，该方法还包括：根据电子设备的加速度确定用户由运动状态转换为停止状态，且电子设备连接有Wi-Fi网络。可以理解的，用户在等待电梯时，通常由走动转换到停止，进而电子设备可以通过速度的变化确定用户由运动状态转换为停止状态，触发预测用户是否等待进入目标电梯，进而可以进一步确定用户是否等待进入目标电梯。
在一种可能的实现方式中，该方法还包括：确定电子设备当前连接的Wi-Fi网络信号强度小于第七阈值，将当前连接的Wi-Fi网络切换为蜂窝网络。电子设备当前连接的Wi-Fi网络信号强度小于第七阈值时，可以认为用户进入电梯后电梯关闭导致当前连接的Wi-Fi网络信号强度骤降，此时电子设备可以将应用的数据流从Wi-Fi网络切换到蜂窝网络(信号覆盖相应电梯的蜂窝网络)，保证用户进入电梯后可以通过蜂窝网络上网，大大降低了应用的上网卡顿概率，能更好地提升用户的上网体验。
在一种可能的实现方式中，电子设备包括围栏管理模块，围栏管理模块用于当确定用户进电梯或出电梯，且电子设备连接有Wi-Fi网络，采集用户进电梯或出电梯时的第二Wi-Fi列表信息；根据第二Wi-Fi列表信息聚类生成至少一个电梯对应的地理围栏的围栏数据，或者将第二Wi-Fi列表信息发送至服务器，并从服务器接收至少一个电梯对应的地理围栏的围栏数据。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请的描述中，除非另有说明，“至少一个”是指一个或多个，“多个”是指两个或多于两个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
为了下述各实施例的描述清楚简洁，首先给出相关概念或技术的简要介绍：
体验质量(quality of experience，QoE):终端用户对移动网络提供的业务性能的主观感受。QoE可以通过接近量化的方法来表示终端用户对业务与网络的体验和感受，并反映当前业务和网络的质量与用户期望间的差距。
从移动通信网络的角度来说，要想获得更好的QoE的最佳方案就是提供一个优良的端到端的服务质量(quality of service，QoS)。广义的QoS为“决定用户满意程度的服务性能的综合效果”，包含多个层面较为广泛的内容。狭义QoS为底层分组数据传输的性能指标，如时延、抖动、带宽、误码等。QoS机制主要负责从网络的角度进行业务管理和提供业务的差异性，网络实体根据不同的质量需求来处理不同业务。但从终端用户的角度来体验QoS是一个更广、更主观的问题，即QoE所定义的范畴。
钩子(HOOK)函数：钩子函数实际上是一个处理消息的程序段。每当特定的消息发出，在没有到达目的窗口前，钩子函数可以先捕获该消息，亦即钩子函数先得到控制权。钩子函数可以加工处理(改变)该消息，也可以不作处理而继续传递该消息，还可以强制结束消息的传递。
数据流：本申请实施例中，将两个电子设备(例如，手机和应用程序的服务器)之间传输的数据序列记为数据流。数据流也可以称为业务流。在实际应用中，基于数据流的业务场景分类，数据流可以包括视频流、音频流、下载流、会话流等。
地理围栏：是使用定位系统网络(例如，全球卫星定位系统(global positioning system，GPS)网络、北斗卫星导航系统(beidou navigation satellite system，BDS)网络)和/或本地射频标识符(例如，Wi-Fi接入点(Wi-Fi节点)、蓝牙信标)在特定位置周围创建虚拟边界，该虚拟边界可以称为地理围栏。可以将地理围栏与硬件/软件应用程序配对，使得应用程序可以根据程序参数的指示以某种方式对地理边界进行响应。
本申请实施例中，特定位置可以是电梯，即可以在电梯周围创建虚拟边界，电梯周围的虚拟边界即是电梯对应的地理围栏(地理围栏可以简称为围栏)。可以将电梯 对应的围栏与视频类应用、游戏类应用等应用程序关联起来。视频类应用、游戏类应用等应用程序可以基于电子设备是否处于电梯对应的围栏进行相应处理。例如，当电子设备处于电梯对应的围栏中时，视频类应用可以对当前正在播放的视频或即将要播放的视频进行缓存、降低分辨率等操作；当电子设备不在电梯对应的围栏中时，视频类应用可以停止对当前正在播放的视频或即将要播放的视频进行缓存、恢复视频的分辨率等操作。
网络通道：两个电子设备之间交互数据的通道。为了便于描述，可以将一个电子设备通过无线网卡与其他电子设备之间建立的网络通道记为Wi-Fi网络；将一个电子设备通过数据业务网卡与其他电子设备之间建立的网络通道记为蜂窝网络。
其中，无线网卡为支持无线局域网(Wireless Local Area Network，WLAN)上网的装置；数据业务网卡为支持长期演进(long term evolution，LTE)、第五代移动通信技术(5th generation mobile communication technology，5G)、全球移动通讯系统(global system for mobile communications，GSM)，通用分组无线服务(general packet radio service，GPRS)等移动通信技术上网的装置。
在实际应用中，网络通道的质量随用户所处的环境而变化。例如，当用户处于封闭的金属环境内时，例如电梯中，电梯关闭后，电梯的金属门吸收电磁波信号造成Wi-Fi网络信号的大幅衰减，从而造成用户上网卡顿，导致用户体验较差。
以电子设备为手机为例说明用户所处的环境对网络通道质量的影响。参见图1A中的(a)，用户使用手机中的游戏应用A玩游戏，其中，手机中的应用A通过手机中的无线网卡与应用A的服务器A建立网络连接，应用A和服务器A之间产生的数据流A(例如，游戏对战时产生的数据流)通过手机上的无线网卡和无线路由器之间的Wi-Fi网络传输。当用户进入电梯后，电梯关闭会造成Wi-Fi网络信号的骤降，进而导致数据流A减小，用户使用应用A时出现卡顿的现象，导致用户体验较差。
为了解决上述问题，参见图1A中的(b)，手机可以将数据流A切换到手机的数据业务网卡和基站之间的蜂窝网络上，以通过该蜂窝网络与服务器A传输数据流A，进而减小Wi-Fi网络信号骤降带来的上网卡顿。
然而，上述手机将Wi-Fi网络切换为蜂窝网络切换的时机是通过手机上内置的加速度传感器检测到用户乘坐电梯后，将Wi-Fi网络切换为蜂窝网络。即手机通过检测用户进入电梯且电梯运行后用户的移动状态来判断是否将Wi-Fi网络切换为蜂窝网络。对于用户而言，此时电梯已经关门并运行，已经使得应用A的数据流A减小，造成用户上网卡顿。
鉴于此，本申请实施例提供一种网络加速方法，在用户在电梯口附近等待期间，电子设备的操作系统可以向当前正在运行的应用通知用户等电梯事件，使得当前正在运行的应用可以根据用户等电梯事件进行提前缓存应用数据和/或降低分辨率等处理，以便后续用户在电梯内时可以继续查看应用的相关内容(例如，继续刷短视频，继续看电影等)。进一步的，在电梯关门瞬间，电子设备可以将应用的数据流从Wi-Fi网络切换到蜂窝网络，从而保证了用户进入电梯后依然能有流畅的上网体验，大大降低了应用的上网卡顿概率，能更好地提升用户的上网体验。

其中，应用层中存在各种应用，例如视频类应用，游戏类应用等。
服务层中存在网络加速服务模块、感知模块、路径管理模块和围栏管理模块。

策略层中设有流量管理模块和决策模块。
其中，流量管理模块用于对内核层上报的数据流进行统计，评估各个数据流的网络质量。
决策模块可以根据用户是否进出电梯执行相应的处理。例如，当确定用户进入电梯后，执行系统加速策略，请求一条新的网络通道进行调优(例如，可以将应用的业务从Wi-Fi网络切换到蜂窝网络)。当确定用户出电梯后，恢复应用的业务到Wi-Fi网络(即将应用的业务从蜂窝网络切换回Wi-Fi网络)。
内核层存在策略执行模块和流量上报模块。其中，流量上报模块用于收集数据流信息，并上报收集的数据流信息。策略执行模块用于执行网络通道的切换。
在本申请另一实施例中，上述实施例中一个模块(组件)可以拆分为两个或多个模块，或者位于同一层级的两个或多个模块可以合并为同一模块。

示例性的，如图3中的(a)所示，手机显示桌面201。响应于用户在桌面201点击设置应用的图标202的操作，如图3中的(b)所示，手机可以显示设置界面203。设置界面203中可以包括WLAN选项204，还可以包括搜索框以及个人账号、蓝牙、 移动网络、桌面和壁纸等功能选项。响应于用户点击WLAN选项204对应的控件的操作，如图3中的(c)所示，手机可以显示WLAN界面205。WLAN界面205中可以包括WLAN开关206。WLAN开关206为开启状态，表示手机可以连接WLAN进行上网。WLAN界面205中还可以包括网络加速选项207，以及更多WLAN设置选项和可用WLAN列表，可用WLAN列表可以包括手机当前扫描到的多个WLAN网络的名称(例如HONOR1、HONOR2、HONOR3等)和信号强度标识等。响应于用户点击网络加速选项207对应的控件的操作，如图3中的(d)所示，手机可以显示网络加速界面208。网络加速界面208中可以包括网络加速功能的文字说明209，文字说明209表示网络加速功能的作用是“评估当前网络质量，智能使用WLAN和移动数据提升上网体验，此过程会联网并消耗部分移动数据流量”。可选的，若用户开启荣耀智慧能力，网络加速将提供更智能的服务。用户可以点击链接“荣耀智慧能力与隐私的声明”来查看荣耀智慧能力的说明。其中，荣耀智慧能力开启后，操作系统可以收集用户使用手机的习惯，根据用户的习惯为用户提供个性化服务。网络加速界面208中还可以包括网络加速(LINK Trubo)对应的开关210。开关210为开启状态，表示用户同意开启网络加速功能，从而手机可以评估当前网络质量，智能使用WLAN和移动数据提升上网体验。当然，用户可以选择关闭开关210，即关闭网络加速功能。在开关210下方，可以显示文本框211，文本框211中的文字用于向用户说明网络加速功能的效果和流量使用情况。例如，网络加速功能开启后，提升下载速度35％，使用流量100M；减少网络卡顿40次，使用流量40M。需要说明的是，网络加速功能可以包括并发加速功能212和协同加速功能214。并发加速功能212包括多通道下载模式213，用户可以通过控件217进入多通道下载模式的设置界面，开启或关闭多通道下载模式。多通道下载模式213开启时，电子设备连接WLAN和移动网络时，可以同时使用多个网络通道并发下载，获得更极速的下载体验。图3中的(d)中多通道下载模式213是已关闭状态。协同加速功能214包括智能模式215和自定义模式216。智能模式215下，可以基于用户流量消耗情况和应用使用偏好，智能开启需要网络加速的应用。用户可以通过控件218开启或关闭智能模式。图3中的(d)中控件218为选中状态，智能模式开启。自定义模式216下，用户可以手动开启需要加速(网络加速)的应用。用户可以通过控件219开启或关闭自定义模式。图3中的(d)中控件219为未选中状态时，自定义模式关闭。用户选择协同加速功能214的智能模式215或自定义模式216时，相应应用程序(智能模式215下智能开启的需要网络加速的应用，或自定义模式216下用户手动选择的需要网络加速的应用)在前台运行时，若发生网络卡顿，电子设备可以将卡顿的网络通道切换到通信质量更好的网络通道，获得更好的上网体验。
如图4中的(a)所示，响应于用户选中控件219以开启自定义模式216的操作，如图4中的(b)所示，手机可以显示手机安装的各种应用程序的信息(图标、名称等)及其对应的开关。例如，手机可以显示微信对应的开关221、QQ对应的开关222、视频应用对应的开关223、抖音对应的开关224和音乐应用对应的开关225等。用户可以根据自己的需求手动选择需要加速的应用程序。例如，用户可以开启微信对应的开关221、QQ对应的开关222、视频应用对应的开关223、抖音对应的开关224，表示用户在使用微信QQ视频应用和抖音时，手机需要开启网络加速以保证 用户的使用体验。
参见图5，为本申请实施例提供的基于图2所示的各个模块实现的一种网络加速方法的时序图，包括两部分，第一部分是电梯对应的地理围栏的生成过程，包括步骤301a；第二部分是对用户到达、进入或走出电梯事件的预测和相应的网络加速过程，包括步骤301b-337。
301a、围栏管理模块采集电梯口附近的Wi-Fi信息，聚类生成电梯对应的围栏。
可以理解的，围栏是一个地域概念，可以指代有边界的地理区域。示例性的，参见图6，为一种电梯对应的围栏的示意图，电梯对应的围栏覆盖电梯周围区域。其中，电梯可以是指用户经常使用的电梯。用户经常使用的电梯可以包括用户的住所(家)附近的电梯，用户的办公室附近的电梯，用户常去的餐厅、商超附近的电梯等。
可以理解的是，电梯周围通常有多个固定的Wi-Fi接入点。例如，对于一梯多户的住宅楼，某一楼层的电梯口附近会有多个住户家中设置的Wi-Fi接入点。多个住户家中设置的Wi-Fi接入点的BSSID不同。又例如，对于办公楼，某一楼层的电梯口附近会有多个Wi-Fi接入点。其中，多个Wi-Fi接入点的BSSID不同(例如，一家公司面积比较大，安装了多个Wi-Fi接入点(无线访问接入点(wireless access point,AP)或者无线路由器)，该公司可以将多个Wi-Fi接入点的SSID设置为相同，但多个Wi-Fi接入点的BSSID不同)。参见图6，电梯对应的围栏内包括AP1、AP2、AP3、AP4、AP5等Wi-Fi接入点，这些Wi-Fi接入点是用户进出电梯时电子设备可以扫描到的Wi-Fi接入点。
电子设备可以在用户进出电梯(进电梯和/或出电梯)时采集Wi-Fi信息。电子设备可以根据加速度计等传感器的数据确定用户是否进出电梯。例如，若加速度计检测到电子设备的加速度从零开始增加，然后又降低为零，确定用户处于乘坐电梯的场景，并即将出电梯。
在一些实施例中，电子设备在用户进出电梯时采集到的Wi-Fi信息可以包括电子设备在用户进电梯前或出电梯后预设时间(例如，10-30秒)内采集到的Wi-Fi信息。也就是说，电子设备可以缓存用户进电梯前或出电梯后10-30秒内扫描到的Wi-Fi接入点的BSSID和信号强度。其中，电子设备采集到的Wi-Fi信息包括用户进电梯前或出电梯后电子设备连接的Wi-Fi接入点的地址和信号强度信息，以及电子设备扫描到的Wi-Fi列表信息。电子设备扫描到的Wi-Fi列表信息可以包括电子设备在电梯口扫描(搜索)到的至少一个Wi-Fi接入点的地址。可选的，Wi-Fi列表还可以包括电子设备在电梯口搜索到的至少一个Wi-Fi接入点的信号强度。示例性的，Wi-Fi接入点的地址可以是BSSID。Wi-Fi网络信号的强度可以是(received signal strength indication，RSSI)。可选的，Wi-Fi列表中还可以包括电子设备的开机时间和Wi-Fi信号的中心频率等，本申请不做限定。
为了更加准确地表征目标电梯所处的实际地理位置，本申请实施例可以通过多次采集Wi-Fi列表信息的方式生成地理围栏的围栏数据，例如图7所示的实施例。如图7所示，电子设备存储的至少一个围栏数据通过以下步骤预先获得：
S1、当根据加速度的变化状态确定用户进/出电梯，且电子设备连接有Wi-Fi网络，采集Wi-Fi列表信息。
可以理解的是，每次用户进/出电梯时电子设备可以采集Wi-Fi列表信息，一段时间(例如，一周、两周、一月)内电子设备可以采集多个Wi-Fi列表信息。
在一种可能的设计中，可以通过用户进出电梯时连接的Wi-Fi网络的BSSID作为该电梯对应的地理围栏的标识，从而区分不同电梯对应的地理围栏。例如，用户在住所乘坐电梯上下楼的应用场景下，可以采用电子设备在住所连接的Wi-Fi网络的BSSID作为住所的目标电梯的地理围栏的标识。又例如，用户在办公室乘坐电梯上下楼的应用场景下，可以采用在办公室连接的Wi-Fi网络的BSSID作为对应办公室的目标电梯的地理围栏的标识。
S2、当电子设备连接同一个Wi-Fi接入点时采集到的Wi-Fi列表的数目超过预设阈值，电子设备选取这些Wi-Fi列表(电子设备连接同一个Wi-Fi接入点采集到的全部Wi-Fi列表)中地址相同的Wi-Fi接入点，根据地址相同的Wi-Fi接入点的信息得到电梯对应的地理围栏的围栏数据。
可选的，预设阈值可以是2、3、4或者更大的数值，本申请实施例对此不做限定。
可以理解的，电子设备连接同一个Wi-Fi接入点时采集到的Wi-Fi列表可以是指电子设备连接相同Wi-Fi接入点(例如，住所的Wi-Fi接入点)的情况下，用户在不同时间进出电梯时采集得到的Wi-Fi列表信息。
以BSSID表示Wi-Fi接入点的地址，以RSSI表示Wi-Fi网络信号强度为例，示例性说明电子设备连接同一个Wi-Fi接入点时采集到的Wi-Fi列表的记录。
参见表1，电子设备每次进或出电梯时记录的Wi-Fi列表信息可以包括用户进或出电梯时电子设备连接的Wi-Fi接入点的BSSID和RSSI，以及电子设备当时所搜索到的Wi-Fi接入点的BSSID和RSSI。可选的，电子设备每次进或出电梯时记录的Wi-Fi列表信息还可以包括用户进或出电梯的时间戳。
表1
示例性的，以预设阈值为2，当Wi-Fi列表的记录数目超过2时，电子设备选取该2个Wi-Fi列表中Wi-Fi接入点地址相同的Wi-Fi接入点。比如表1中，第一条记录和第二记录之间地址相同的BSSID为6c:16:32:17:3c:95、6c:16:32:17:3c:51和 6c:17:32:27:2c:92，因此生成的围栏数据中Wi-Fi接入点的地址分为6c:16:32:17:3c:95、6c:16:32:17:3c:51和6c:17:32:27:2c:92，如表2所示。
进一步的，可以对地址相同的Wi-Fi接入点的信号强度取平均值生成围栏数据。参见表1，BSSID为6c:16:32:17:3c:95的Wi-Fi接入点对应的RSSI分别为-50dBm和-48dBm，对-50dBm和-48dBm取平均值为-49dBm。参见表2，围栏数据包括BSSID为6c:16:32:17:3c:95的Wi-Fi接入点的RSSI为-49dBm。同理，BSSID为6c:16:32:17:3c:51的Wi-Fi接入点的RSSI为-61dBm，BSSID为6c:17:32:27:2c:92的Wi-Fi接入点的RSSI为-71dBm。
表2
本申请实施例提供的方法，通过对不同时间下用户进出同一部电梯(例如，住所的电梯)时采集到的Wi-Fi列表信息的记录取交集和计算平均网络信号强度的方式，来生成电梯(例如，住所的电梯)的围栏数据，可以使得生成的围栏数据更接近电梯(例如，住所的电梯)所在实际的地理位置，进而提高电子设备预测用户是否等待进入电梯的准确程度。
在另一种可能的设计中，如图8所示，电子设备生成电梯对应的地理围栏的围栏数据(即电梯对应的围栏数据)的过程可以包括：电子设备获取用户进出电梯时采集到的Wi-Fi信息；根据电子设备在用户进出电梯时连接的BSSID(即电子设备进出电梯时连接的Wi-Fi接入点的BSSID)对Wi-Fi列表(即电子设备进出电梯时扫描到的Wi-Fi列表)进行分类，得到用户进出电梯时连接的多个BSSID中每个BSSID对应的多个Wi-Fi列表。可以将电子设备连接同一个BSSID时采集到的多个Wi-Fi列表中每个Wi-Fi列表中的每个Wi-Fi接入点的信号强度转换为距离，对所述多个Wi-Fi列表中地址相同的Wi-Fi接入点对应的距离取均值得到列表A。其中，电子设备连接同一个BSSID时采集到的多个Wi-Fi列表可以是在最近一段时间(例如，最近7天，最近14天等)采集到的。基于预设距离过滤(剔除)列表A中的Wi-Fi接入点得到列表B。列表B即围栏数据。换句话说，列表A中Wi-Fi接入点对应的距离大于预设距离时，丢弃该Wi-Fi接入点，得到列表B，列表B中每个Wi-Fi接入点对应的距离都不大于(小于或等于)预设距离。这样，可以使得后续生成的围栏的范围更加精确。然后，可以使用采集到的Wi-Fi列表匹配列表B，即对列表B进行有效性校验。当Wi-Fi列表的数据与列表B代表的围栏数据的相似度(包括BSSID的和距离的相似度)满足预设条件(例如，相似度达到80％)时，认为列表B代表的围栏数据有效，即可以用列表B表示电梯的围栏数据。
基于上述方法，电子设备可以创建至少一个电梯对应的围栏。例如，电子设备可 以创建用户的住所(家)附近的电梯对应的围栏，用户的办公室附近的电梯对应的围栏，用户常去的餐厅、商超附近的电梯对应的围栏等。
在一些实施例中，电子设备可以将采集到的Wi-Fi列表信息发送给服务器(云服务器)，服务器根据电子设备采集到的Wi-Fi列表信息生成围栏数据，服务器生成围栏数据的过程可以参考上文中电子设备生成围栏数据的过程。电子设备可以从服务器接收围栏数据并存储起来。
在一种可能的设计中，服务器可以接收多个电子设备在同一个电梯处上报的Wi-Fi列表信息，选取这些Wi-Fi列表(多个电子设备连接同一个Wi-Fi接入点采集到的全部Wi-Fi列表)中地址相同的Wi-Fi接入点，根据地址相同的Wi-Fi接入点的信息生成电梯对应的地理围栏的围栏数据，使得生成的围栏数据更加精确。
301b、响应于用户打开应用A的操作，应用A启动。
应用A是应用层的一个应用程序，例如可以是视频应用。响应于用户打开应用A的操作，应用A启动，电子设备可以显示应用A的相关界面。此时应用A是前台应用，即应用A的程序代码正在CPU中运行。
以应用A为游戏应用为例，如图9中的(a)所示，响应于用户在桌面401点击游戏应用的图标402的操作，视频应用启动，手机可以显示视频应用的主界面。响应于用户在视频应用的主界面选择一个视频进行播放，如图9中的(b)所示，手机可以显示视频播放界面403。视频播放界面403可以包括当前正在播放的视频的显示窗口、媒体标题和选集按钮等控件。
或者，步骤301b可以是应用A从后台切换至前台，此时应用A仍是前台应用。
302、感知模块感知到应用A启动，查询应用A是否支持网络加速。
示例性的，感知模块可以通过RunningProcess、ActivityLifecycleCallbacks、UsageStatsManager等函数监测当前的前台应用(例如，应用A)，并获取前台应用的标识。或者，若终端设备为Android系统，可以通过Android自带的无障碍功能监测当前的前台应用，并获取前台应用的标识。或者，若终端设备为Linux系统，可以读取Linux系统内核保存在/proc目录下的process进程信息监测当前的前台应用，并获取前台应用的标识。具体判断过程可以参考现有技术，在此不做赘述。其中，应用的标识用于唯一识别一个应用，可以和应用的包名具有一一对应的关系，也可以采用应用的包名。
感知模块中可以包括应用配置库，应用配置库中存储了多个应用程序是否支持网络加速的信息，多个应用程序包括应用A。如表3所示，示例性示出部分应用程序是否支持网络加速的信息。
表3

或者，应用配置库中可以仅存储支持网络加速的应用程序的信息。如表4所示，示例性示出部分支持网络加速的应用程序的信息。
表4
实际应用中，该应用配置库还可以存储多个应用标识，每个应用标识采用不同的字符表示该应用标识表示的应用是否支持网络加速。作为示例，可以采用“1”表示支持网络加速，采用“0”表示不支持网络加速。其他确定应用是否支持网络加速的方式不再一一举例。
在一种可能的实施方式中，如图3中的(d)所示，若用户选择协同加速功能214的智能模式215，应用配置库中的多个应用程序可以是基于用户流量消耗情况和应用使用偏好，智能确定出的需要网络加速的应用程序。
在另一种可能的实施方式中，如图4中的(a)所示，若用户选择协同加速功能的自定义模式216，应用配置库中的多个应用可以是基于用户的手动设置确定出的需要网络加速的应用。例如，如图4中的(b)所示，若用户开启微信对应的开关221、QQ对应的开关222、视频应用对应的开关223、抖音对应的开关224，应用配置库中的多个应用程序可以包括微信QQ视频应用和抖音
303、若确定应用A支持网络加速，感知模块向决策模块发送网络质量评估请求。
若感知模块通过查询应用配置库确定应用A支持网络加速，可以向决策模块发送网络质量评估请求。决策模块接收到网络质量评估请求后，可以执行步骤304。
其中，网络质量评估请求用于请求决策模块进行网络质量评估。网络质量评估请求中可以包括应用标识、应用的配置信息以及网络质量评估的标准。其中，应用的配置信息是指应用进行业务时的报文特征，报文特征为应用传输数据流时的数据包的头部特征。
或者，感知模块感知到应用A切换到前台，可以通知决策模块，决策模块可以查询应用配置库确定应用A是否支持网络加速，若确定应用A支持网络加速，可以执行步骤304。
304、决策模块向内核层的流量上报模块注册报文监测钩子。
报文监测钩子可以周期性探测应用A当前使用的网络通道的路径，以及监测应用A使用的网络通道传输的数据流的通信参数和统计信息。
应用A在实现某个功能时，可能产生一个或多个数据流。若检测到产生多个数据流，可以周期性检测应用A的每条数据流的通信参数和统计信息。
下面具体描述报文监测钩子如何监测应用A的数据流的通信参数和统计信息，并将监测到的数据流的通信参数和统计信息发送给流量管理模块。
电子设备的系统中存在Netfilter组件(钩子函数管理组件)，通过该组件可以获取到特定应用标识对应的应用(例如，应用A)的数据流。流量上报模块可以通过调用Netfilter组件获取应用A的数据流的报文。具体实现时，流量上报模块上报给流量管理模块的信息不仅包括应用A的数据流的报文，还包括应用A的数据流的报文的一些通信参数和统计信息。
参见图10，流量上报模块可以预先注册报文监测钩子(例如，nf_hook钩子函数)。在流量上报模块调用Netfilter组件后，Netfilter组件上报应用A的数据流的报文，流量上报模块接收到Netfilter组件上报的数据流的报文之后，调用预先注册的nf_hook钩子函数。
该nf_hook钩子函数对接收到的数据流的报文进行以下操作：报文解析、查流表和报文分析等操作。
在进行报文解析时，可以查看该报文是否存在应用标识以及该报文的四元组(或五元组)，以得到解析结果。若存在应用标识，则可以确定该报文对应的应用程序。四元组中包括源IP、目的IP、源端口、目的端口；五元组中包括：源IP、目的IP、源端口、目的端口以及协议号。另外，报文(数据包)本身也携带了头部特征。数据流的报文的四元组(或五元组)以及报文的头部特征等参数可以统称为数据流的通信参数。
在进行报文解析之后，根据解析结果查询流表，并更新流表的统计信息。流表中存储了各个应用中数据流的标识信息、以及各个数据流的报文总数、收发字节数(包括接收字节数和发送字节数)、错误包数量等。进一步的，可以根据报文总数确定是否下行无响应，例如，连续两个周期内接收到的报文总数相同，则确定下行无响应。可以根据收发字节数确定传输速率，例如，上一周期和本周期接收到的字节数的差值与周期的比值为本周期下行速率。可以根据报文中携带的序列号确定丢包情况，例如，丢包率(loss tolerance或packet loss rate)可以是缺失的序列号的数目与现有的序列号的数目的比值。当然，上述参数的确定方式仅用于举例，在实际应用中，还可以通过其他方式确定上述参数。数据流的报文总数、错误包数量、丢包率、收发字节数、速率(上行速率、下行速率)等信息可以统称为数据流的统计信息。实际应用中，各个流的统计信息还可以包括其他信息，例如，数据流随时间变化的流量分布信息、数据流的报文的时延信息等。
当然，若流表中不存在某个数据流的标识信息或相关统计信息时，则可以在流表中增加该数据流的标识以及相关的统计信息。
在查流表并更新流表信息之后，则可以对报文进行分析。例如，过滤报文，从而得到全部或部分报文。
作为一种示例，该过滤过程可以是过滤某个数据流的心跳包报文。则经过过滤处理后，得到该数据流的心跳包报文。该过滤处理过程可以是：通过预先设置某些特征，将满足该特征的报文保留。即满足预先设置的某些特征的报文就为过滤后的报文。
其中，心跳包报文为按照一定的时间间隔存在于数据流中的报文。心跳包报文在 固定位置(例如第6个字节)存在固定特征(例如0x64或0x65)。由于该心跳包报文为按照一定时间存在的报文，因此可以基于该心跳包报文计算获得时延(例如，手机向服务器发送心跳请求报文开始，到手机接收到服务器反馈的心跳响应报文为止，总共经历的时间)。
上述示例以过滤心跳包为例进行说明，实际应用中，还可以过滤处理以获得满足其它特征的数据包报文。
作为另一示例，过滤条件还可以包括：选择保留特定长度的数据包报文。在具体实现时，确定数据包报文的长度是否为预先设置的特定长度，若是，则保留该报文，若否，则将该报文过滤掉。
经过上述处理后，得到的过滤后的部分报文被存储在套接字缓存(Socket-Buffer，SKB)队列(queues)中。
SKB队列中存储的数据流的报文上报时的策略包括：立即上报和定期上报。
若为立即上报，流量上报模块中的特定线程及时查看队列，将队列中的报文及时上报给流量管理模块。
若为定期上报，流量上报模块中设置了定时器，基于该定时器设置的时间以一定的周期查看SKB队列中的报文，将队列中的部分或全部报文上报给流量管理模块。
当然，实际应用中，SKB队列中存储的数据流的报文有些是需要立即上报的，有些是需要定期上报的。同样的原理，流量上报模块中的特定线程及时查看队列，将队列中的需要立即上报的报文及时上报给流量管理模块。流量上报模块中还设置了定时器，基于该定时器设置的时间以一定的周期查看SKB队列中的报文，将队列中的需要定期上报的报文上报给流量管理模块。
需要说明，上报报文时，还可以一并上报该报文相关的统计信息。
基于上述理解，流量上报模块并不是将Netfilter组件发送的所有报文均上报给流量管理模块。而是，将满足特定特征的报文(可以携带该满足特定特征的报文的通信参数和统计信息)上报给流量管理模块。同时上报该满足特征的报文相关的通信参数和统计信息。
作为示例，若报文1和报文2均属于同一数据流的报文。接收到报文1后查流表时，根据报文1更新流表中关于该数据流的统计信息，然而，报文1不满足特定特征，所以报文1被过滤掉，不会上报给流量管理模块。接收到报文2后查流表时，根据报文2更新流表中关于该数据流的统计信息，报文2满足特定特征，所以报文2不会被过滤掉，报文2会被上报给流量管理模块。即虽然上报了部分报文，然而，统计信息是基于该数据流下的所有报文得到的。
305、流量上报模块向流量管理模块周期性上报数据流的通信参数和统计信息。
其中，数据流的通信参数可以包括协议类型、源IP地址和端口/目的IP地址和端口、报文特征、报文信息(payload)等。其中，协议类型为应用传输数据流时的协议类型，源IP地址和端口为发送数据流时使用的IP地址和端口，目的IP地址和端口为接收数据流时使用的IP地址和端口，报文特征为应用传输数据流时的数据包的头部特征。数据流的通信参数可以是从数据流的报文的四元组或五元组获取到的。
例如，某社交通信类应用在进行音视频通话时，数据流对应的数据包的头部特征 为97开头，即data[0]＝97，传输数据包时采用UDP协议，源IP地址和端口分别为221.11.6.XX和8080，目的IP地址和端口分别为221.14.4.XX和5050。
数据流的统计信息可以包括往返时延(round trip time，RTT)、丢包率、收发字节数、速率(上行速率、下行速率)等。其中，收发字节数包括发送字节数(即上传流量)和接收字节数(即下载流量)。丢包率为丢失数据包数量占所发送数据包的比率。上行速率为发送数据流的速率，下行速率为接收数据流的速率。RTT表示从电子设备(发送端)发送数据开始，到接收收到来自对端(接收端)的确认(对端接收到数据后便立即发送确认)，总共经历的时长。
例如，某社交通信类应用在进行音视频通话时，收发字节数分别为10MB/8MB，上行速率和下行速率分别为200kbit/180kbit，RTT为50ms。
当然，实际应用中，流量上报模块还可以向流量管理模块上报应用网络报文的其他参数，例如流间隔时间、包间隔时间、包大小和流量分布等信息，本申请不做限定。
可选的，流量上报模块可以通过一条消息上报上述应用网络报文的通信参数和统计信息，或者，可以通过多条消息分别上报应用网络报文的通信参数和统计信息，本申请不做限定。
306a、流量管理模块根据数据流的通信参数和统计信息周期性进行网络质量评估得出当前QoE测量结果。
流量管理模块接收到应用A的数据流的通信参数和统计信息后，可以查询应用A的流特征库，比如可以根据报文的协议类型、端口、报文协议头等特征识别出前台运行的应用的业务场景(例如，识别出是抖音的短视频播放场景)并记录到流表中。其中，应用A的流特征库中存储该应用A的数据流的各种信息，例如，应用A使用当前网络时采用的协议的协议特征，应用A使用当前网络时传输的数据包的头部特征等。当然，还可以包括应用A使用当前网络时的流量特征等，在此不做限定。
流量管理模块可以定期对前台运行的应用的数据流进行QoE评估。实际应用中，不同的应用对应的QoE评估条件可以相同或不同。其中，QoE评估条件可以是指连续几个周期内数据流的统计信息满足的条件。同一个应用的不同业务场景对应的QoE评估条件可以相同或不同。例如，游戏应用的对战场景和跑图场景的QoE评估条件可以不同，又例如，视频应用中的视频选择场景、视频播放场景，小窗播放场景的QoE评估条件可以不同，基于不同的业务场景设计不同的QoE评估条件可以使得QoE评估更加准确。不同业务场景可以通过通信参数进行区分，通信参数满足的条件不同时，通信参数对应的业务场景也不同。同一个应用的同一个业务场景可以对应一种或多种QoE评估条件。每种QoE评估条件对应一个QoE测量结果(也可以称为QoE评估结果)。多种QoE评估条件可以对应同一个QoE测量结果，满足该多种QoE评估条件中的任一种时，可以得到相同的QoE测量结果。
以王者荣耀的对战场景为例，王者荣耀的对战场景对应的QoE评估条件可以是根据丢包率和/或时延满足的条件评估对战的卡顿情况。例如，若对战场景中丢包率满足3s内连续出现2次丢包20％的条件，和/或，对战场景的时延满足4s内连续出现2次时延超过200ms的条件，可以认为王者荣耀的对战场景的QoE测量结果为差，即对战过程中发生卡顿。
示例性的，QoE测量结果可以包括：优(流畅不卡顿)、中(可能卡顿)和差(卡顿)。例如，QoE测量结果为优的标识可以为00，QoE测量结果为中的标识可以为10，QoE测量结果为差的标识可以为11。
如表5所示，可以根据数据流的通信参数满足的条件对前台运行的应用的当前业务场景进行区分。进一步的，可以根据不同业务场景对应的不同QoE评估条件确定相应业务场景的QoE测量结果。应用程序的数据流的通信参数和统计信息分别满足不同条件时，QoE测量结果是不同的。
表5
其中，表5中的com.tencent.mm为微信包名，com.tencent.tmgp.sgame为王者荣耀包名。表5中一个条目表示应用程序的数据流的通信参数和统计信息分别满足相应条件时，可以得到相应的QoE测量结果。例如，王者荣耀的数据流采用udp协议+任意端口+0x10报文头部时，且该数据流在5个周期(统计周期)内连续3个周期时 延超过150ms，或在4个周期内连续3个周期丢包超过20％，则QoE测量结果为差。
表5仅列举了部分应用程序的数据流的QoE评估条件(包括数据流的通信参数和统计信息分别需要满足的条件)和QoE测量结果，且仅用于示例。在实际应用中还可以采用其他不同的QoE评估条件得到QoE测量结果。
在一些情况下，基于表5得到的QoE测量结果可能出现误判的情况。例如，用户使用短视频类应用时，若用户刷到某短视频，短视频类应用开始通过网络通道下载该短视频并缓存已经下载的该短视频的部分数据帧，再从缓存中获取该短视频的数据帧并开始播放。若该短视频的播放时长为15秒，以用户刷到该短视频为时间起点，从时间起点开始至第2秒，单位时间的下载速率会快速增大；从第2秒至第5秒，单位时间的下载速率会快速降低至0；从第5秒至第15秒播放结束，单位时间的下载速率维持0。
若采用上述表5中的条件，若确定端视频应用的数据流连续多个周期的时延超过350ms或连续多个周期的下行速率(均值)小于51kb/s，则表示数据流的QoE测量结果为差。上述示例中，在第5秒至第15秒期间，连续多个周期内的速率(均值)均为0，可能会判定当前数据流发生卡顿，即在当前网络通道上的传输质量较差。
然而，在具体应用中，在第5秒至第15秒期间，该应用的数据流所在的网络通道的网络质量并不差，只是当前没有从其他电子设备下载数据流的需求，所以连续多个周期内的速率均为0。鉴于此，本申请实施例提供另一种评估短视频类应用的QoE测量结果的方法。短视频类应用的数据流的特征如下：采用http协议、通过get向服务器请求视频内容、且get数据包中携带mp4字段。
参见图11，为本申请实施例提供的网络通道质量较好时，短视频类应用的数据流的速率特点。视频流的速率呈周期分布，每个周期包括速率不为0的时间段和速率为0的时间段。
例如，图11中，视频流的速率分布包括：连续的第一时间段、第二时间段和第三时间段，其中，第一时间段、第三时间段的速率不为0，第二时间段的速率为0。在第一时间段中的第一部分的平均速率大于第一值，表示视频流的传输质量满足要求，不需要提升网络质量，电子设备在第三时间段通过第一网卡传输视频流。
参见图12，视频流的速率分布还可以包括：连续的第四时间段、第五时间段和第六时间段，第四时间段和第六时间段的速率不为0，第五时间段的速率为0。在第四时间段中的第二部分的平均速率小于或等于第一值，表示视频流的传输质量不满足要求，需要提升网络质量，电子设备在第六时间段通过电子设备的第二网卡传输视频流，为了评判标准统一，可以设置第二部分的时长和第一部分的时长相等。
为了使得速率为0的情况下，评判标准更精确，还可以设置第一时间段中的第一部分的结束时间和第一时间段的结束时间相同，第四时间段中的第二部分的结束之间和第四时间段的结束时间相同。
根据图11所示的速率特点和图12所示的速率特点可以理解：速率为0的情况比较特殊，在评估短视频类应用的视频流的传输质量时需要将速率为0的情况单独考虑。
速率不为0的一段时间段内，该段时间内可以选取一部分时间(例如，和第一部分的时长相同)，可以记为第七时间段，确定第七时间段的平均速率小于或等于第一 值，电子设备在第八时间段通过第二网卡传输视频流，其中，第八时间段的开始时间为第七时间段的结束时间。当然，确定第七时间段的平均速率大于第一值，电子设备在第八时间段通过第一网卡传输视频流。
在具体实现时，可以将速率为0的情况和速率不为0的情况分开考虑。其中，本申请实施例中的速率表示均值周期(例如，300ms、400ms、500ms、600ms、700ms等)内视频流的平均下行速率。
平均速率不存在0的情况：多个(例如，2个，3个，4个，5个等)均值周期内的平均速率均较小，则该数据流的传输质量较差。当然，也可以是1个均值周期内的平均速率值较小，则该数据流的传输质量较差。
平均速率存在0的情况：由于网络原因导致平均速率出现0的情况，通常平均速率出现0之前，平均速率已经开始变小(在具体实现时，可以取一段时间内的平均速率，该段时间的结束时间可以为速率变为0的时间)，这种情况才需要提升传输质量；由于当前播放的短视频缓存结束导致平均速率出现0的情况，通常平均速率出现0之前平均速率仍然较大，这种情况不需要提升传输质量。所以，平均速率出现0时，需要追溯到平均速率首次变为0的均值周期之前一个均值周期(最后一个非0速率的均值周期)的平均速率；在具体实现时，可以将平均速率出现0的周期的平均速率延用平均速率首次变为0时上一个均值周期(最后一个非0速率的均值周期)的平均速率。当然，也可以理解每出现平均速率为0的情况，均延用上一均值周期的平均速率。然后在多个均值周期内的平均速率均较小时，则该数据流的传输质量较差。
鉴于上述描述，可以设置以多个均值周期的平均速率作为参考。首先根据单个均值周期(可以记为第一周期)的平均速率确定当前均值周期的周期传输质量，然后根据多个均值周期的周期传输质量确定当前数据流的数据流传输质量。
在确定单个均值周期的周期传输质量时，若平均速率不为0，则可以在平均速率小于或等于阈值A(可以等于第一值，也可以不等于第一值)的情况下，判定当前均值周期的周期传输质量为差；在平均速率大于阈值A的情况下，判定当前均值周期的周期传输质量为优。若平均速率为0，在延用上一均值周期的平均速率的情况下，相当于延用了上一均值周期的周期传输质量(差或优)。因此在上一均值周期的周期传输质量为差的情况下，认为当前均值周期的周期传输质量也为差，在上一均值周期为优的情况下，认为当前均值周期的周期传输质量也为优。本申请实施例对平均速率为0的情况采用延用上一均值周期的周期传输质量还是延用上一均值周期的速率不做限定。当然，实际应用中，平均速率为0时，也可以根据过去多个均值周期(例如，3,5,7个等)的周期传输质量确定，例如，根据多个均值周期传输质量的标识中的众数确定。
综上所述，单个均值周期的周期传输质量的结果包括以下：
优：本均值周期的平均速度大于或等于阈值A(例如，50kb/s)；或者，平均速率等于0、且上一个均值周期的周期传输质量为优。
差：平均速度小于阈值A、且不等于0；或者，平均速率等于0、且上一个均值周期的周期传输质量为差。
在确定各个均值周期的周期传输质量之后，在当前均值周期可以查看本均值周期以及本均值周期之前连续的M-1个均值周期的周期传输质量，在连续的M个均值周期 的周期传输质量中，若存在至少N个均值周期的周期传输质量为差，则判定数据流的数据流传输质量为差。其中，N小于或等于M。若少于N个均值周期的周期传输质量为差，则判定数据流的数据流传输质量为优。
306b、流量管理模块周期性向决策模块上报当前QoE测量结果。
需要说明的是，应用A启动之后，流量上报模块可以周期性检测应用A使用的网络的网络质量，并周期性上报应用网络报文的通信参数和统计信息。流量管理模块根据应用网络报文的通信参数和统计信息周期性进行网络质量评估得出QoE测量结果，并周期性向决策模块通知当前QoE测量结果，直至应用A关闭。
也就是说，在应用A启动期间(或前台运行期间)，流量上报模块一直在周期性检测应用A使用的网络的网络质量，流量管理模块一直在周期性进行网络质量评估得出QoE测量结果，并周期性向决策模块通知当前QoE测量结果。
即，步骤305-步骤306b在应用A启动期间(或前台运行期间)可以周期性执行。
另外，应用A启动之后，还可以包括以下步骤：
307、应用A向网络加速服务模块发送注册请求，该注册请求用于请求电梯预测服务，以便应用A可以感知用户是否到达电梯口。
其中，注册请求可以携带应用A的标识以及需要注册的服务(电梯预测服务)的标识。电梯预测服务可以感知用户是否到达电梯或进入电梯。应用A注册电梯预测服务后，可以获知用户是否到达电梯或进入电梯。
308a、网络加速服务模块向感知模块发送注册请求。
308b、感知模块向围栏管理模块发送注册请求。
309a、围栏管理模块记录注册电梯预测能力的应用信息，向感知模块发送注册结果。
围栏管理模块接收到应用A的注册请求后，对注册的应用进行鉴权和校验，例如可以进行以下判断：(1)查询应用配置库确定应用A是否支持网络加速；(2)确定应用A是否在前台运行；(3)确定应用A是否具备电梯预测权限。需要说明的是，应用A若需要注册电梯预测服务，首先可以在开发者网站(例如，荣耀开发者网站)上注册开发者，注册开发者成功后可以申请appid和电梯预测服务kit的权限。kit是一种用于向应用层(的应用程序)提供基础服务的软件开发工具包(software development kit，SDK)。后续感知模块检查应用A是否是荣耀开发者网站上注册过的合法用户，并且查看应用A是否具有电梯预测服务kit的权限(即电梯预测权限)。其中，具有电梯预测权限的应用可以从电子设备的操作系统获取电梯事件(例如，用户到达电梯口等电梯事件、用户进入电梯事件)，根据电梯事件确定是否进行网络加速处理，网络加速处理包括提前缓存第一应用的运行数据、降低第一应用的帧率、降低第一应用的码率、降低第一应用的分辨率中的至少一种。
围栏管理模块对注册的应用鉴权和校验成功后，例如确定应用A支持网络加速，应用A在前台运行，且应用A具备电梯预测权限，可以记录应用A的应用信息。并且，围栏管理模块可以向感知模块课发送注册结果，注册结果为注册成功。这样，后续围栏管理模块检测到电梯事件后会通知给对应的注册者(例如，应用A)。
309b、感知模块向网络加速服务模块发送注册结果。
310、网络加速服务模块向应用A发送注册结果。
需要说明的是，步骤302-步骤306b和步骤307-步骤310之间没有必然的执行先后顺序，可以是先执行步骤302-步骤306b，再执行步骤307-步骤310；也可以是先执行步骤307-步骤310，再执行步骤302-步骤306b；还可以是同时执行步骤302-步骤306b和步骤307-步骤310；本实施例对上述各步骤之间的执行先后顺序不作具体限定。
311、决策模块向围栏管理模块上报卡顿信息。
当决策模块从流量管理模块接收到卡顿信息(即QoE测量结果为差(卡顿))后，可以将卡顿信息发送给围栏管理模块。
312、围栏管理模块接收到卡顿信息后采集卡顿指纹信息，根据卡顿指纹信息对电梯对应的Wi-Fi连接列表(Wi-Fi列表)进行修正。
其中，卡顿指纹信息可以包括时间戳(接收到卡顿信息的时间)、接收到卡顿信息后采集到的Wi-Fi连接列表(包括Wi-Fi接入点的地址和信号强度)、GPS等信息。可选的，卡顿指纹信息还可以包括电子设备的型号等信息。
电子设备可以根据卡顿指纹信息对电梯对应的Wi-Fi列表进行修正，这样可以使得围栏数据更加精确。如果电子设备连接某电梯(例如，第一电梯)的Wi-Fi接入点(例如，第一Wi-Fi接入点)时，围栏管理模块从未接收到决策模块上报的卡顿信息，认为用户乘坐该电梯时不会发生卡顿(例如，电梯里有Wi-Fi的AP的场景)，则无需为该电梯生成围栏数据，即可以过滤掉电子设备在该电梯处采集的Wi-Fi连接列表等信息。
在一些实施例中，电子设备可以将采集的卡顿指纹信息定期上传到云服务器，以便云服务器根据卡顿指纹信息对围栏数据进行更新。
313、围栏管理模块监听用户的运动状态变化，在用户的运动状态变化满足预设条件时，检测是否存在电梯对应的围栏，若检测到电梯对应的围栏，确定用户到达电梯口。
其中，预设条件是针对用户乘坐电梯时的运动特征设置的。可以理解的是，用户乘坐电梯时一般需要先步行到电梯口，在电梯口前静止等待电梯门打开。示例性的，预设条件可以是用户从步行状态到停止，并保持相对静止状态(例如，持续5s)。其中，用户的运动状态(例如，步行状态或静止状态)可以是根据陀螺仪采集的数据确定的。
可选的，电子设备内可以设置有加速度传感器、陀螺仪传感器等识别用户的状态是步行状态还是停止状态。
可以理解的，用户在等待电梯时，通常由走动转换到停止，进而电子设备可以通过速度的变化确定用户由运动状态转换为停止状态，触发预测用户是否等待进入目标电梯，进而可以进一步确定用户是否等待进入目标电梯。
可选的，检测是否存在电梯对应的围栏前，可以判断当前时间是否处于预设时间段内，预设时间段可以是上下班高峰时间段(例如，8：30-9：30、17：30-18：30)。可以理解的是，在预设时间段内用户乘坐电梯的可能性较高，因此在预设时间段内检测是否存在电梯对应的围栏可以避免功耗浪费。
围栏管理模块检测周围是否存在电梯对应的围栏，例如可以是检查电子设备当前 连接的Wi-Fi对应的BSSID是否有对应的围栏数据，若连接的Wi-Fi对应的BSSID存在围栏数据，电子设备可以进行Wi-Fi信息扫描。围栏管理模块获取扫描到的Wi-Fi信息与电子设备存储的围栏数据进行匹配，确定扫描到的BSSID是否满足预设条件，预设条件例如可以是扫描到的BSSID与某电梯对应的围栏数据(目标围栏数据)中的BSSID有重叠(即有相同的BSSID)，且相同BSSID中信号强度差小于t dbm的BSSID的个数占目标围栏数据中所有BSSID数量的比值>80％，若扫描到的BSSID满足预设条件，匹配成功，则上报到达电梯口事件。
可选的，电子设备存储有至少一个电梯对应的围栏。例如，电子设备可以存储用户的住所(家)附近的电梯对应的围栏，用户的办公室附近的电梯对应的围栏，用户常去的餐厅、商超附近的电梯对应的围栏等。在电子设备存储的至少一个电梯对应的围栏中，每个电梯对应的围栏对应一个Wi-Fi接入点的地址(例如，BSSID)，该Wi-Fi接入点是用户进出该电梯时常用(经常连接的)的Wi-Fi接入点。例如，在目标电梯处于办公场所的场景下，可以使用用户在办公场所的目标电梯处连接的Wi-Fi接入点的地址来对应该办公场所的电梯对应的围栏。又例如，在目标电梯处于住所的场景下，可以使用用户在住所出所连接的Wi-Fi接入点的地址来对应住处的电梯对应的围栏。
若当前电子设备扫描到的Wi-Fi列表信息与目标围栏数据之间相同的Wi-Fi接入点地址的数量满足第一条件，确定用户等待进入目标电梯。
可选的，第一条件可以是当前电子设备扫描到的Wi-Fi列表信息与目标围栏数据之间相同的Wi-Fi接入点地址的数量超过第二阈值。第二阈值可以是1、2、3、4或者更大的数值，本申请实施例不对第二阈值的具体数值做限定。
示例性的，以第二阈值为2为例进行示例性说明，参见表6，当前电子设备扫描到的Wi-Fi列表和目标围栏数据之间相同的Wi-Fi接入点的地址为：连接的地址1、地址2、地址4和地址5，当前电子设备扫描到的Wi-Fi列表和目标围栏数据之间相同的Wi-Fi接入点的地址的数量超过2，电子设备可以确定用户等待进入目标电梯。
表6
可选的，第一条件还可以是当前电子设备扫描到的Wi-Fi列表信息与目标围栏数据之间相同的Wi-Fi接入点地址的数量占所述目标围栏数据中所有Wi-Fi接入点数量的比值超过第三阈值。
可选的，第三阈值可以是50％、60％、70％或者80％，本申请实施例不对第三阈值的具体数值做限定。
示例性的，以第三阈值为70％为例进行示例性说明，再次参见表6，当前电子设备扫描到的Wi-Fi列表和目标围栏数据之间相同的Wi-Fi接入点的地址的数量为4个，目标围栏数据中所有Wi-Fi接入点数量为5个，相同的Wi-Fi接入点的地址的数量的占比为80％，超过第三阈值的70％，电子设备可以确定用户等待进入目标电梯。
本申请实施例提供的上述方法，在预测用户是否等待进入目标电梯时，可以通过电子设备预先存储的围栏数据与当前电子设备扫描到的Wi-Fi网络列表进行对比，当满足第一条件时，电子设备可以确定用户等待进入目标电梯。
在一种可能的设计中，确定用户等待进入目标电梯之前，确定相同的Wi-Fi接入点地址中存在的可匹配Wi-Fi接入点的数量满足第二条件，可匹配Wi-Fi接入点为相同的Wi-Fi接入点地址中对应的网络信号强度之差小于第一阈值的Wi-Fi接入点。可选的，第一阈值可以是5、8、10或者12等，本申请实施例对第一阈值的具体数值不做限定。
示例性的，以第一阈值为10为例进行示例性说明，再次参见表6，当前电子设备扫描到的Wi-Fi列表与目标围栏数据之间相同的Wi-Fi接入点的地址为：连接的地址1、地址2、地址4和地址5。其中，当前电子设备扫描到的Wi-Fi列表的连接的地址1与目标围栏数据的连接的地址1之间的网络信号强度之差为2，小于第一阈值，即连接的地址1为可匹配Wi-Fi接入点。当前电子设备扫描到的Wi-Fi列表的地址2与目标围栏数据的地址2之间的网络信号强度之差为18，大于第一阈值，即地址2不是可匹配Wi-Fi接入点。同理，地址4是可匹配Wi-Fi接入点，地址5不是可匹配Wi-Fi接入点。
可选的，第二条件可以是可匹配Wi-Fi接入点的数量超过第四阈值。可选的，第四阈值可以是2、3、4或者更大的数值，本申请实施例不对第四阈值的具体数值做限定。
示例性的，以第四阈值为3进行示例性说明，再次参见表6，结合上述可匹配Wi-Fi接入点的说明，表6中可匹配Wi-Fi接入点的数量为2个，即表6中的当前电子设备扫描到的Wi-Fi列表不满足第二条件，电子设备确定用户没有等待进入目标电梯。
可选的，第二条件可以是可匹配Wi-Fi接入点的数量占所述目标围栏数据中所有Wi-Fi接入点数量的比值超过第五阈值。可选的，第五阈值可以是50％、60％、70％或者80％，本申请实施例不对第五阈值的具体数值做限定。
示例性的，以第五阈值为70％进行示例性说明，再次参见表6，结合上述可匹配Wi-Fi接入点的说明，表6中可匹配Wi-Fi接入点的数量为2个，表6中目标围栏数据中的所有Wi-Fi接入点的数量为5个，可匹配Wi-Fi接入点的数量目标围栏数据中所有Wi-Fi接入点数量的比值为40％，即电子设备确定用户没有等待进入目标电梯。
本申请实施例提供的上述方法，在通过围栏数据预测用户是否等待进入目标电梯时，在通过当前电子设备扫描到的Wi-Fi接入点与目标围栏数据之间相同的Wi-Fi接入点的地址进行预测时，引入网络信号强度，增加围栏数据表征对应的目标电梯所在的地理位置的相似度，提高预测的准确度。
在实际应用时，如图13所示，用户1201携带电子设备1202从T1位置步行到T2位置，在T2位置停止步行，若用户在T2位置处于静止状态(没有位移，但是不代表身体不可以动)超过5s，则电子设备1202可以启动围栏检测，检测周围是否存在电梯对应的围栏。具体的，电子设备1202可以进行Wi-Fi列表扫描，并将扫描到的Wi-Fi列表与预先存储的围栏数据进行比对，如果信号强度差小于t dbm的相同BSSID的个数占目标围栏数据中所有Wi-Fi接入点数量的比值<80％，则认为匹配不成功，预测结果为用户不在电梯围栏内，判定用户未到达电梯口。其中，t可以是5、8、10或者12等。
例如，电子设备1202在T2位置连接的BSSID和扫描到的Wi-Fi列表可以如表7所示。电子设备1202在T2位置连接的Wi-Fi接入点为AP1(AP1对应BSSID1，即电子设备1202在T2位置连接BSSID1)，AP1的信号强度为-50。电子设备1202在T2位置扫描到的Wi-Fi接入点可以包括AP2、AP5，AP7、AP8。AP2、AP5，AP7、AP8分别对应的BSSID为BSSID1、BSSID2、BSSID5、BSSID7、BSSID8，分别对应的信号强度为-60、-42、-32、-30。
表7
以电梯对应的围栏对应的Wi-Fi列表为表8为例。可见，电子设备1202在T2位置扫描到的Wi-Fi列表和电梯对应的围栏对于的Wi-Fi列表中相同的BSSID可以包括BSSID1、BSSID2、BSSID5。BSSID1、BSSID2、BSSID5的信号强度差分别为2、18、35。信号强度差小于t dbm(例如，t＝10)的相同BSSID的个数占比<80％。因此匹配不成功，预测结果为用户不在电梯围栏内，判定用户未到达电梯口。
表8
进一步的，用户可以从T2位置步行到T3位置，在T3位置停止步行，若用户在T3位置处于静止状态超过5s，则电子设备1202可以再次启动围栏检测，检测周围是否存在电梯对应的围栏。具体的，电子设备1202可以进行Wi-Fi列表扫描，并将扫描到的Wi-Fi列表与预先存储的围栏数据进行比对，如果信号强度差小于t dbm的相同BSSID的个数占比>80％，则认为匹配成功，预测结果为在电梯围栏内，即判定用户已到达电梯口，可以向感知模块上报到达电梯口事件。
例如，电子设备1202在T2位置扫描到的Wi-Fi列表可以如表9所示。电子设备1202在T3位置连接的Wi-Fi接入点为AP1(AP1对应BSSID1，即电子设备1202在T2位置连接BSSID1)，AP1的信号强度为-50。电子设备1202在T3位置扫描到的Wi-Fi接入点可以包括AP2、AP3，AP4、AP5。AP2、AP3，AP4、AP5分别对应的BSSID为BSSID1、BSSID2、BSSID5、BSSID7、BSSID8，分别对应的信号强度为-80、-58、-48、-78。
表9
以电梯对应的围栏对应的Wi-Fi列表为表8为例，可见，电子设备1202在T3位置扫描到的Wi-Fi列表和电梯对应的围栏对于的Wi-Fi列表中相同的BSSID可以包括AP1、AP2、AP3、AP4、AP5。信号强度差小于t dbm(例如，t＝10)的相同BSSID的个数占比>80％。因此匹配成功，预测结果为用户在电梯围栏内，判定用户到达电梯口。
参考图13，假设应用A为短视频应用，如图14所示，电子设备在T1位置可以连接BSSID1播放视频，视频分辨率正常；在T2位置可以连接BSSID1播放视频，视频分辨率正常；在T3位置可以连接BSSID1播放视频，并且提前缓存，降低视频分辨率。
314、围栏管理模块向感知模块通知用户到达电梯口等电梯事件。
315、感知模块向网络加速服务模块通知用户到达电梯口等电梯事件。
316、网络加速服务模块向应用A通知用户到达电梯口等电梯事件。
317、应用A接收到用户到达电梯口等电梯事件，提前进行网络加速。
应用A接收到用户到达电梯口等电梯事件，确定用户等待进入目标电梯，应用A(第一应用)进行网络加速处理，网络加速处理包括提前缓存第一应用的运行数据、降低第一应用的帧率、降低第一应用的码率或降低第一应用的分辨率中的至少一种。
以应用A为视频类应用为例，应用A接收到用户到达电梯口等电梯事件后，应用A可以提前缓存当前播放的视频或即将播放的视频，和/或降低当前视频的分辨率，以减少后续视频卡顿现象，提升用户体验。
以应用A为游戏类应用为例，应用A接收到用户到达电梯口等电梯事件后，应用A可以切换游戏服务器、降低游戏帧率，以减少后续的卡顿现象，提升用户体验。
318、围栏管理模块确定用户进入电梯。
用户从T3位置进入电梯，电梯关门瞬间电子设备检测到WI-FI信号强度骤降(信号强度下降幅度大于预设阈值)，围栏管理模块基于WI-FI信号强度的变化判定用户已进入电梯，可以向感知模块上报进入电梯事件，通知用户进入电梯。可选的，第七阈值可以是-60dBm、-70dBm、-75dBm等，本申请实施例不对第七阈值的具体数值做限定。
319、围栏管理模块通知感知模块用户进入电梯事件。
320、感知模块通知决策模块用户进入电梯事件。
321、决策模块接收到用户进入电梯事件后，执行系统加速策略，请求一条新的网络通道进行调优。
322、决策模块向路径管理模块发送更优路径请求。
其中，更优路径请求用于请求一条相比当前网络通道质量更优的网络通道。
323、路径管理模块激活并探测网络质量，确定存在相比当前网络通道质量更优的网络通道。
路径管理模块接收到决策模块发送的更优路径请求时，可以激活并探测各个网络通道的网络质量，确定是否存在相比当前网络通道质量更优的网络通道。
在实际应用中，若电子设备中设有2.4GHz频段的无线网卡1、5.0GHz频段的无线网卡2、运营商A的数据业务网卡1和运营商B的数据业务网卡2。则可以默认无线网卡1或无线网卡2中的一个为主Wi-Fi，另一无线网卡为副Wi-Fi；默认运营商A的数据业务网卡1和运营商B的数据业务网卡2中的一个为主卡，另一个数据业务网卡为副卡。
作为示例，2.4GHz频段的网络通道为主Wi-Fi网络，5.0GHz频段的网络通道为辅Wi-Fi网络，数据业务网卡1对应的网络通道为主蜂窝网络，数据业务网卡2对应的网络通道为辅蜂窝网络。
在主Wi-Fi网络可用的情况下，系统默认电子设备或前台应用当前的主用网络为主Wi-Fi网络，在主Wi-Fi网络不可用的情况下，系统默认电子设备或前台应用当前的主用网络为主卡蜂窝网络。在主卡蜂窝网络不可用的情况下，系统默认电子设备或前台应用当前的主用网络为副Wi-Fi网络，在副Wi-Fi网络不可用的情况下，系统默认电子设备或前台应用当前的主用网络为副卡蜂窝网络。
在应用A开启后在前台运行时，应用A按照上述规则使用主用网络；即使应用A在前台时，系统将应用A中的部分数据流切换到其他网络上，在应用A切换到后台后，应用A中的数据流恢复使用系统默认的主用网络；在应用A从后台切换到前台后，应用A继续使用系统默认的主用网络。
路径管理模块可以按照主Wi-Fi、主卡网络、副Wi-Fi和副卡网络的顺序依次请求，直到找到一条可用且质量满足要求(网络质量优于当前正在使用的网络通道)的网络通道。
324、路径管理模块向决策模块通知质量更优的网络通道。
路径管理模块可以将上述可用且质量满足要求的网络的网络路径通知给决策模块。
325、决策模块向内核层的策略执行模块通知将应用A的数据流切换到更优的网络通道上。
即决策模块触发切换，以便将应用A的数据流切换到更优的网络通道上。例如，可以将应用A的数据流从Wi-Fi网络切换到蜂窝网络(蜂窝网络在电梯中的信号质量优于Wi-Fi网络)。
326、策略执行模块将应用A的数据流切换到更优的网络通道上。
这样，应用A可以通过更优的网络通道进行上网，可以提高用户体验。
在一些实施例中，决策模块可以向内核层的策略执行模块通知将应用A的数据流切换到多条质量较优(网络质量优于当前正在使用的网络通道)的网络通道上。策略执行模块将应用A的数据流切换到多条质量较优的网络通道上，以便应用A可以通过多条质量较优的网络通道进行上网，可以提高用户体验。
327、围栏管理模块检测到用户出电梯。
328、围栏管理模块通知感知模块用户出电梯事件。
329、感知模块通知决策模块用户出电梯事件。
330、决策模块接收到用户出电梯事件后，恢复应用A的业务到Wi-Fi网络。
即决策模块可以将应用A的业务从蜂窝网络切换回Wi-Fi网络(Wi-Fi网络在电梯外的信号质量优于蜂窝网络)。
当应用A停止运行或切换到后台时，可以执行以下步骤：
331、应用A向网络加速服务模块发送去注册请求，请求停止电梯预测服务。
332、网络加速服务模块向感知模块发送去注册请求。
333、感知模块向围栏管理模块发送去注册请求，通知围栏管理模块停止应用A的电梯预测服务。
334、围栏管理模块停止应用A的电梯预测服务，不再向应用A通知用户是否进入电梯。
335、感知模块向决策模块通知停止应用A的网络加速和QoE测量。
感知模块感知到应用A停止运行或切换到后台或接收到应用A发送的去注册请求后，通知决策模块停止对该应用进行网络加速，恢复数据流，释放已请求的网络。
336、决策模块向策略执行模块通知停止应用A的网络加速和QoE测量。
337、策略执行模块停止应用A的网络加速和QoE测量。

基于本申请实施例提供的网络加速方法，在用户在电梯口附近等待期间，电子设备的操作系统可以向当前正在运行的应用通知用户等电梯事件，使得当前正在运行的应用可以根据用户等电梯事件进行提前缓存应用数据和/或降低分辨率等处理，以便后续用户在电梯内时可以继续查看应用的相关内容(例如，继续刷短视频，继续看电影等)。进一步的，在电梯关门瞬间，电子设备可以将应用的数据流从Wi-Fi网络切换到蜂窝网络，从而保证了用户进入电梯后依然能有流畅的上网体验，大大降低了应用的上网卡顿概率，能更好地提升用户的上网体验。
