Description

无线保真WiFi通信方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
目前，手机普遍支持无线保真(wireless fidelity，WiFi)热点功能。手机(记为接入点)开启WiFi热点功能之后，其他支持WiFi上网的设备(记为终端设备)可以通过接入点开启的WiFi热点接入到网络设备中。
终端设备通过WiFi热点向网络设备发送数据的过程具体为：终端设备通过WiFi热点向接入点发送数据；接入点接收到该数据之后，向网络设备转发该数据。
由于终端设备随时可能通过WiFi热点发送数据，因此，接入点需要始终保持WiFi热点的开启，以便于随时接收来自终端设备的数据。但是接入点始终保持WiFi热点的开启状态将会产生较大的功耗。
发明内容
本申请提供一种无线保真WiFi通信方法及装置，解决了现有技术中接入点开启WiFi热点之后，WiFi热点产生较大功耗的问题。
为解决上述问题，本申请采用如下技术方案：
第一方面，提供一种无线保真WiFi通信方法，包括：接入点开启WiFi热点；接入点选择性地开启WiFi低功耗模式；响应开启WiFi低功耗模式，接入点周期性地广播低功耗指示帧，其中，低功耗指示帧承载有低功耗参数，低功耗参数用于指示接入点进入WiFi低功耗模式后，处于休眠状态的至少一个非连续时间段。
基于上述技术方案，接入点通过周期性广播低功耗指示帧，可以大大增加终端设备接收到低功耗指示帧的概率，从而降低终端设备无法接收到低功耗指示帧而在接入点的WiFi热点处于休眠状态时向接入点发送数据导致数据包丢失的情况。
此外，一般来说，接入点的WiFi热点处于休眠状态的多个时间段不会频繁发生变化，即使终端设备在本周期内未接收到低功耗指示帧，也可以根据上一个周期接收到的低功耗指示帧确定接入点的WiFi热点处于休眠状态的多个时间段。从而进一步降低了终端设备的数据包丢失的概率。
结合上述第一方面，在一种可能的实现方式中，该方法还包括：接入点根据接入WiFi热点的终端设备的信息，选择性地开启WiFi低功耗模式。
结合上述第一方面，在一种可能的实现方式中，该方法还包括：在至少一个终端设备接入WiFi热点的情况下，接入点确定至少一个终端设备是否支持WiFi低功耗模式；若一个或多个终端设备均支持WiFi低功耗模式，则接入点开启WiFi低功耗模式。
基于此，接入点根据终端设备的信息有选择性的开启WiFi低功耗模式，在接入WiFi热点的终端设备均支持WiFi低功耗模式的情况下，接入点开启WiFi低功耗模式，可以降低接入点WiFi热点产生的功耗。在存在终端设备不支持WiFi低功耗模式的情 况下，接入点不开启WiFi低功耗模式，可以避免导致终端设备发送的数据无法被接入点接收到的情况。
结合上述第一方面，在一种可能的实现方式中，该方法还包括：接入点确定是否接收到来自至少一个终端设备中每个终端设备的低功耗支持帧，低功耗支持帧用于表征终端设备支持WiFi低功耗模式；若是，则接入点确定至少一个终端设备均支持WiFi低功耗模式；若否，则接入点确定至少一个终端设备中包括不支持WiFi低功耗模式的终端设备。
基于此，终端设备可以通过向接入点发送低功耗支持帧，向接入点指示该终端设备支持WiFi低功耗模式，接入点可以根据是否接收到每个终端设备的低功耗支持帧，确定接入点是否支持WiFi低功耗模式。
结合上述第一方面，在一种可能的实现方式中，该方法还包括：在接入点处于开启WiFi热点且没有终端设备接入WiFi热点的状态，接入点开启WiFi低功耗模式。
基于此，接入点在无终端设备接入WiFi热点的情况下，开启WiFi低功耗模式，降低WiFi热点产生的功耗。
结合上述第一方面，在一种可能的实现方式中，该方法还包括：在接入点开启WiFi热点之后，若接入点未接收到来自终端设备的接入请求，则确定接入点处于开启WiFi热点且没有终端设备接入WiFi热点的状态。
结合上述第一方面，在一种可能的实现方式中，该方法还包括：在一个或多个接入WiFi热点的终端设备均与WiFi热点断开连接之后，确定接入点处于开启WiFi热点且没有终端设备接入WiFi热点的状态。
基于此，接入点可以确定在刚开启WiFi热点还没有终端设备接入的情况下，以及在接入WiFi热点的终端设备全部与WiFi热点断开连接的情况下，开启WiFi热点。
结合上述第一方面，在一种可能的实现方式中，该方法还包括：接入点生成强制开启WiFi低功耗模式的强制开启信息；响应于强制开启信息，接入点开启WiFi低功耗模式。
基于此，接入点可以在确定强制开启信息之后强制开启WIFI低功耗模式，适用于需要优先降低接入点的WIFI热点的功耗的场景。
结合上述第一方面，在一种可能的实现方式中，该方法还包括：接入点接收来自未接入WiFi热点的终端设备的WiFi热点接入请求；响应于WiFi热点接入请求，接入点关闭WiFi低功耗模式。
基于此，接入点在终端设备请求接入WiFi热点时，关闭WiFi低功耗模式。这样，在终端设备接入WiFi热点的过程中接入点始终处于接收状态，提高终端设备接入WiFi热点的成功率。
结合上述第一方面，在一种可能的实现方式中，非连续的多个时间段的时长根据在预设时间段内接入点与终端设备之间传输的数据量确定。
基于此，接入点可以在WiFi热点传输数据量大的情况下指示时间较长非连续的多个时间段，以保证数据传输的速率和时延。
接入点可以在WiFi热点传输数据量小的情况下，指示时间较短的非连续的多个时间段，以降低接入点的WiFi热点的功耗。
结合上述第一方面，在一种可能的实现方式中，该方法还还包括：响应WiFi低功耗模式开启，接入点在用户界面上显示第一标识，第一标识用于表征WiFi低功耗模式已开启。

结合上述第一方面，在一种可能的实现方式中，第一标识包括第一图标和第二图标，第一图标为WiFi热点图标，第二图标为WiFi低功耗模式图标。
基于此，接入点可以通过在WiFi热点图标增加WiFi低功耗模式图标表征接入点已开启WiFi低功耗模式。
结合上述第一方面，在一种可能的实现方式中，该方法还包括：接入点关闭WiFi低功耗模式。
基于此，接入点可以通过关闭WiFi低功耗模式，保证WiFi热点的常规运行。

第二方面，提供一种通信方法，包括：终端设备向接入点发送低功耗支持帧；低功耗支持帧用于表征终端设备支持WiFi低功耗模式；接入点为开启WiFi热点的接入点。
终端设备接收接入点周期性广播的低功耗指示帧，其中，低功耗指示帧承载有低功耗参数，低功耗参数用于指示接入点进入WiFi低功耗模式后，处于休眠状态的至少一个非连续时间段。
在至少一个非连续时间段以外的时间段，终端设备通过WiFi热点向接入点发送数据。
基于上述技术方案，终端设备通过向接入点发送低功耗支持帧指示自身支持WiFi低功耗模式。在接入点开启WiFi低功耗模式之后，终端设备在接入点的WiFi热点处于休眠状态时，不向接入点发送数据，终端设备确定在接入点处于休眠状态的时间段以外的时间段，向接入点发送数据。这样，可以避免终端设备发送的数据无法被接入点接收，而导致的终端设备的数据包丢失。

如图1所示，本申请实施例提供的通信方法可以应用于如图1所示的通信系统100中，如图1所示，该通信系统100中包括：接入点10，以及一个或多个终端设备20。接入点10和终端设备20之间通过WiFi热点的无线链路通信连接。
接入点10用于开启WiFi热点，并接收终端设备20通过WiFi热点发送的数据；接入点10还可以用于向网络设备转发来自终端设备20通过WiFi热点发送的数据。 此外，接入点10还可以接收来自网络设备的数据，并通过WiFi热点向终端设备20发送数据。
终端设备20用于通过WiFi热点与接入点10建立通信连接，并通过WiFi热点向接入点10发送数据，或者通过WiFi热点接收来自接入点10的数据。
以上，对本申请的应用场景进行了简要介绍。
当前，随着移动数据流量资费的降低，用户使用终端设备(记为接入点)开启WiFi热点为其他终端设备(记为终端设备)分享数据流量的场景越来越多。
例如，用户使用手机开启WiFi热点，为其他手机或者笔记本等无线上网设备提供数据流量，其他手机或者笔记本等无线上网设备可以通过使用开启WiFi热点手机的数据流量接入网络。
接入点开启WiFi热点之后，终端设备通过WiFi热点接入接入点的时间，以及终端设备通过WiFi热点向接入点发送数据的时间不固定，因此，接入点无法确定终端设备通过WiFi热点接入接入点的时间，或者终端设备通过WiFi热点向接入点发送数据的时间。
因此，接入点需要持续的在WiFi热点的无线信道中检测是否存在终端设备通过WiFi热点向接入点发送的数据，避免因为接入点未及时接收到终端设备发送的数据，而导致的终端设备发送的数据丢失的情况。在接入点始终处于在WiFi热点的无线信道中检测数据的状态时，接入点产生的功耗将大大增加。
目前，为了降低接入点开启WiFi热点之后产生的功耗，提供了一种用于降低WiFi热点功耗的方法，如图2所示，该方法包括：
步骤a、接入点广播Self-允许发送(clear to send，CTS)帧。
一种可能的实现方式中，接入点开启WiFi热点之后，在一定条件下(例如，在预设时长内接收到终端设备通过WiFi热点发送的数据量小于预设数据量)，接入点生成Self-CTS帧。在此之后，接入点广播该Self-CTS帧。
其中，Self-CTS帧中承载有网络分配矢量(network allocation vector，NAV)指示信息。
NAV指示信息用于指示目标时间段。在该目标时间段内，接入点的WiFi热点进入休眠状态。接收到该Self-CTS帧的终端设备在目标时间段内不通过WiFi热点向接入点发送数据。
其中，接入点的WiFi热点进入休眠状态指的是：接入点不在WiFi热点的无线信道中检测数据。在该状态下，接入点的WiFi热点产生的功耗将大大降低。
步骤b、终端设备接收来自接入点的Self-CTS帧。
具体来说，终端设备接收到来自接入点的Self-CTS帧之后，根据第一Self-CTS帧中的NAV指示信息，确定接入点的WiFi热点进行休眠的时间。在该时间段内，终端设备不通过WiFi热点向接入点发送数据。
在上述方法中，接入点可以通过向终端设备发送Self-CTS帧指示接入点的WiFi热点进入休眠状态的时间。这样，接入点可以在该时间段内指示WiFi热点进入休眠状态，从而降低接入点的WiFi热点产生的功耗。此外，接入点广播Self-CTS帧，以使得终端设备接收到该Self-CTS帧后确定接入点的WiFi热点进入休眠状态的时间。在 该时间内，终端设备不通过WiFi热点向接入点发送数据。
但是，上述方法存在以下问题：
1、Self-CTS帧在WiFi热点的公共无线信道中传输，因此该Self-CTS帧可能被接入另一个接入点的WiFi热点的其他终端设备接收到。另一个接入点为除接入点以外的开启WiFi热点的设备。其他终端设备为接入另一个接入点的WiFi热点的终端设备。
在另一个接入点和接入点距离较近的情况下，接入点和另一个接入点可能会共用公共无线信道。若接入点和另一个接入点共用公共无线信道，接入点通过WiFi热点在公共无线信道中发送的Self-CTS帧可能会被其他终端设备接收到。其他终端设备接收到该Self-CTS帧之后，其他终端设备将会在Self-CTS帧指示的时间段内不向另一个接入点发送数据。这将会导致本来可以通过WiFi热点正常传输数据的另一个接入点和其他终端设备之间无法继续通过WiFi热点传输数据。
2、接入点广播Self-CTS帧之后，接入点无法确认是否每个终端设备都接收到Self-CTS帧。若存在终端设备未接收到该Self-CTS帧，则在该Self-CTS帧指示的时间段内，终端设备仍有可能通过WiFi热点向接入点发送数据。但是，在该时间段内，接入点已经指示WiFi热点进入休眠状态，接入点将无法通过WiFi热点接收终端设备发送的这些数据，从而导致终端设备发送的数据包丢失。
在WiFi热点的使用场景中，WiFi热点的使用的无线信道非常容易受到干扰，Self-CTS帧未被终端设备接收到的几率较大。因此上述方法将会导致终端设备数据包丢失的几率较大。
基于上述问题，本申请提供一种通信方法，该方法包括：接入点开启WiFi低功耗模式之后，接入点将会周期性的广播低功耗指示帧，低功耗指示帧用于指示接入点的WiFi热点处于休眠状态的多个时间段。
接入点通过周期性广播低功耗指示帧，可以大大增加终端设备接收到低功耗指示帧的概率，降低了终端设备在接入点的WiFi热点处于休眠状态时向接入点发送数据的概率，减少了终端设备向接入点发送的据包丢失的情况。
而且，接入点的WiFi热点处于休眠状态的多个时间段不会频繁发生变化，即使终端设备在本周期内未接收到低功耗指示帧，也可以根据上一个周期接收到的低功耗指示帧确定接入点的WiFi热点处于休眠状态的多个时间段。从而进一步降低了终端设备的数据包丢失的概率。
此外，本申请还可以对接入点和终端设备进行关联，关联后的终端设备可以识别低功耗指示帧，未与接入点进行关联的终端设备将无法识别低功耗支持帧。
基于此，即使其他终端设备接收到低功耗指示帧，由于其他终端设备未与接入点关联无法识别该低功耗指示帧，因此其他终端设备也将不会只在低功耗指示帧指示的时间段以外发送数据，保证了其他终端设备仍能够正常使用另一个接入点的WiFi热点。
本申请实施例提供的方法，可以应用到如图1所示的通信系统中，如图3所示，该通信方法包括：
S300、接入点开启WiFi热点。
其中，WiFi热点用于接入点与终端设备通信。
S301、接入点选择性地开启WiFi低功耗模式。
在WiFi低功耗模式下，接入点的WiFi热点在非连续的多个时间段内处于休眠状态。在WiFi热点处于休眠状态时，接入点将不通过WiFi热点接收来自终端设备的数据。
一种可能的实现方式中，接入点在开启WiFi之后，判断当前的条件是否满足开启WiFi低功耗模式的条件。
若满足，则接入点选择开启WiFi低功耗模式。
若不满足，则接入点选择不开启WiFi低功耗模式。
S302、响应开启WiFi低功耗模式，接入点周期性地广播低功耗指示帧。相应的，终端设备接收来自接入点的低功耗指示帧。
其中，低功耗指示帧承载有低功耗参数，低功耗参数用于指示接入点进入WiFi低功耗模式后，处于休眠状态的至少一个非连续时间段。
一种可能的实现方式中，低功耗指示帧承载在接入点广播的Beacon帧中。Beacon帧为WiFi协议中规定的，接入点需要周期性发送的管理帧。在该情况下，接入点广播低功耗指示帧的周期为接入点发送Beacon帧的周期。
需要指出的是，上述非连续的多个时间段的时长，与接入点与终端设备之间传输的数据量有关。
具体来说，在接入点与终端设备传输的数据量较多的情况下，非连续的多个时间段的时长较短，这样接入点与终端设备之间可以使用较多的时间通过WiFi热点传输数据，以满足接入点与终端设备之间通过WiFi热点传输数据的需求。
在接入点与终端设备传输的数据量较少的情况下，非连续的多个时间段的时长较短，这样接入点与终端设备之间可以使用较少的时间通过WiFi热点传输数据，以降低接入点的WiFi热点产生的功耗。
S303、终端设备确定在非连续的多个时间段以外的时间段，向接入点发送数据。
一种可能的实现方式中，终端设备接收到接入点广播的Beacon帧之后，终端设备解析该Beacon帧，确定Beacon帧信息承载的低功耗指示帧。终端设备确定低功耗指示帧指示的接入点的WiFi热点处于休眠状态的非连续的多个时间段。
在该非连续的多个时间段内，终端设备不通过WiFi热点向接入点发送数据，以避免数据包丢失。
在该非连续的多个时间段以外的时间段，接入点的WiFi热点正常工作，终端设备在该非连续的多个时间段以外的时间正常通过WiFi热点向接入点发送数据。
基于上述技术方案，接入点通过周期性广播低功耗指示帧，可以大大增加终端设备接收到低功耗指示帧的概率，降低了终端设备在接入点的WiFi热点处于休眠状态时向接入点发送数据的概率，减少了终端设备向接入点发送的据包丢失的情况。
此外，接入点的WiFi热点处于休眠状态的多个时间段不会频繁发生变化，即使终端设备在本周期内未接收到低功耗指示帧，也可以根据上一个周期接收到的低功耗指示帧确定接入点的WiFi热点处于休眠状态的多个时间段。从而进一步降低了终端设备的数据包丢失的概率。
需要指出的是，在本申请实施例中，接入点可以根据如下三种场景选择性的开启WiFi低功耗模式：场景a、接入点根据接入WiFi热点的终端设备的信息，选择性地开 启WiFi低功耗模式；场景b、接入点根据接入WiFi热点的数量，选择性的开启WiFi低功耗模式；场景c、接入点根据是否生成强制开启信息，选择性的开启WiFi低功耗模式。
下面，分别对场景a、场景b、以及场景c进行具体说明：
场景a、接入点根据接入WiFi热点的终端设备的信息，选择性地开启WiFi低功耗模式。
一种可能的实现方式中，上述终端设备的信息包括：终端设备是否支持WiFi低功耗模式。
相应的，接入点在接入WiFi热点的每个终端设备均支持WiFi低功耗模式的情况下，选择开启WiFi低功耗模式。
接入点在接入WiFi热点的终端设备中存在不支持WiFi低功耗模式的终端设备情况下，选择不开启WiFi低功耗模式。
可选的，接入点可以根据是否接收到来自终端设备的低功耗支持帧，确定终端设备是否支持WiFi低功耗模式。其中，低功耗支持帧用于指示终端设备支持WiFi低功耗模式。
具体来说，接入点在接收到上述每个终端设备发送的低功耗支持帧的情况下，确定每个终端设备均支持WiFi低功耗模式，此时，接入点开启WiFi低功耗模式。
接入点在未接收到上述每个终端设备发送的低功耗支持帧的情况下，确定存在不支持WiFi低功耗模式的终端设备，此时，接入点不开启WiFi低功耗模式。
一种可能的实现方式中，低功耗支持帧承载于终端设备向接入点发送的接入请求Associate Request帧。Associate Request帧是终端设备接入接入点的WiFi热点时向接入点发送的帧。
终端设备支持WiFi热点低功耗指的是：终端设备能够识别接入点发送的低功耗指示帧，确定低功耗指示帧指示的接入点的WIFI热点处于休眠状态的时间段。在这些时间段内，终端设备不通过WiFi热点向接入点发送数据，在这些时间段以外的时间段，终端设备可以通过WiFi热点向接入点发送数据。
需要指出的是，在场景a中，如果终端设备未向接入点发送低功耗支持帧，则表示该终端设备不支持WiFi低功耗模式。终端设备接收到低功耗指示帧之后将无法识别低功耗指示帧中的内容，也就无法确定接入点的WiFi热点进入休眠状态的时间。在该情况下，即使接入点的WiFi热点进入休眠状态，终端设备仍可能通过WiFi热点向接入点发送数据。这将会导致终端设备发送的数据包丢失。
因此，在场景a中，接入点需要在接收到来自每个终端设备的低功耗支持帧的情况下，才能开启WiFi低功耗模式。若存在任一个终端设备未向接入点发送低功耗支持帧，则接入点不开启WiFi低功耗模式。
举例来说，在场景a中，存在三个终端设备接入接入点的WiFi热点，分别为终端设备#1，终端设备#2，终端设备#3。终端设备#1和终端设备#2为支持WiFi低功耗模式的终端设备，终端设备#3为不支持WiFi低功耗模式的终端设备。
在终端设备#1和终端设备#2接入接入点的WiFi热点的过程中，终端设备#1和终端设备#2向接入点发送的Associate Request帧中承载有低功耗支持帧。接入点据此确 定终端设备#1和终端设备#2支持WiFi低功耗模式。
在终端设备#3接入接入点的WiFi热点的过程中，终端设备#3向接入点发送的Associate Request帧中未承载有低功耗支持帧。接入点据此确定终端设备#3不支持WiFi低功耗模式。
在该情况下，接入点确定不开启WiFi低功耗模式。
场景b、接入点根据接入WiFi热点的数量，选择性的开启WiFi低功耗模式。
一种示例，接入点在不存在终端设备通过WiFi热点与接入点进行通信的情况下，开启WiFi低功耗模式。
接入点在存在终端设备通过WiFi热点与接入点进行通信的情况下根据上述场景a中记载的发放确定是否开启WiFi低功耗模式。
其中，不存在终端设备通过WiFi热点与接入点进行通信的场景包括以下至少一项：
接入点刚开启WiFi热点，终端设备尚未接入接入点的WiFi热点。
接入接入点的WiFi热点的终端设备全部与接入点的WiFi热点断开连接。
具体来说，在所述接入点开启所述WiFi热点之后，若所述接入点未接收到来自终端设备的接入请求，则确定所述接入点处于开启所述WiFi热点且没有终端设备接入所述WiFi热点的状态。
或者，在一个或多个接入所述WiFi热点的终端设备均与所述WiFi热点断开连接之后，确定所述接入点处于开启所述WiFi热点且没有终端设备接入所述WiFi热点的状态。
在场景b中，不存在终端设备通过WiFi热点与接入点进行通信，接入点无需通过WiFi热点接收来自终端设备的数据。此时，接入点可以开启WiFi低功耗模式，以降低接入点WiFi热点的功耗。
场景c、接入点根据是否生成强制开启信息，选择性的开启WiFi低功耗模式。
强制开启信息用于指示接入点强制开启WiFi低功耗模式。
具体来说，结合上述场景a和场景b可以确定，接入点可以根据是否所有终端设备都支持WiFi低功耗模式，或者接入WiFi热点的终端设备的数量，确定是否开启WiFi低功耗模式。
但是，在某些情况下，即使WiFi热点的使用条件不满足上述场景a或者场景b中记载的条件，但是为了降低WiFi热点产生的功耗，接入点仍需开启WiFi低功耗模式。
例如，接入点开启省电模式，此时，为了降低WiFi热点产生的功耗，接入点强制开启WiFi低功耗模式。
又例如，用户向接入点发送了用于强制开启WiFi热点低功耗模式的指令，此时，接入点需要强制开启WiFi低功耗模式。
在这些情况下中，接入点生成强制开启信息，并根据强制开启信息开启WiFi低功耗模式。
需要指出的是，接入点可以通过TCP/IP层及TCP/IP层以上的层生成强制开启信息，然后将该强制开启信息发送给WiFi芯片，由WiFi芯片开启WiFi低功耗模式。
基于上述技术方案，本申请提供了接入点需要开启WiFi低功耗模式的三种场景。 基于上述场景a和场景b，接入点可以在避免终端设备发送的数据包丢失的情况下，开启WiFi低功耗模式，达到降低接入点的WiFi热点产生的功耗的目的。基于上述场景c，接入点可以强制开启WiFi低功耗模式，在一些场景下，可以优先保证降低接入点的WiFi热点产生的功耗。
在S300的一种可能的实现方式中，如图4所示，接入点广播的低功耗指示帧用于指示第一时间段中，接入点的WiFi热点处于休眠状态的多个非连续时间段。
接入点将需要指示的第一时间段划分为多个连续的第二时间段，并进一步从每个第二时间段中确定出第三时间段。第三时间段为接入点的WiFi热点处于休眠状态的多个非连续时间段中的一个时间段。
低功耗指示帧分别指示第一时间段的开始时间，第一时间段中包括几个第二时间段，每个第二时间段的时间长度，每个第二时间段中的第三时间段的时间长度。
其中，第一时间段中包括的第二时间段为连续的时间段，第一时间段中包括的第二时间段的时长之和等于第一时间段的时长。第三时间段为非连续的时间段，第三时间段的开始时间与第二时间段的开始时间相同。
一种示例，承载有低功耗指示帧的Beacon帧中至少包括以下至少一个字段：Count字段、Duration字段、Interval字段、Start Time字段。以下结合表1对上述4个字段进行详细说明：
表1
Figure PCTCN2021078342-appb-000001
具体来说，上述Interval字段用于指示图4中示出的的第二时间段的时长，Duration字段用于指示图4中示出的的第三时间段的时长，Count字段用于指示一个第一时间段内包括几个第二时间段，Start Time字段用于指示第一时间段的开始时间。
一种可能的实现方式中，如图5所示，在接入点开启WiFi热点之后，接入点确定是否开启WiFi低功耗模式包括以下S500-S512。下面进行详细说明：
S500、接入点开启WiFiI热点。
S501、接入点开启WiFi低功耗模式。
需要说明的是，在接入点开启WiFi热点之后，用户操作终端设备向接入点的WiFi热点发起接入需要一定的时间。
在这段时间内，接入点的WiFi热点将无需检测终端设备通过WiFi热点发送的数据。因此，在接入点开启WiFi热点之后，接入点可以立即WiFi低功耗模式，以降低 终端设备未发起接入这段时间内，WiFi热点产生的功耗。
S502、接入点接收WiFi热点接入请求。
WiFi热点接入请求为终端设备向接入点发送的用于请求接入WiFi热点的请求。
一种可能的实现方式中，WiFi热点接入请求为终端设备向接入点发送的(authentication，AUTH)帧。
S503、接入点关闭WiFi低功耗模式。
具体来说，在接入点接收到终端设备发送的WiFi热点接入请求之后，接入点和终端设备需要通过WiFi热点进行信令交互，以确定是否允许终端设备接入接入点的WiFi热点。
此时，为了保证终端设备接入WiFi热点的成功率，以及降低终端设备接入WiFi热点的时延，接入点关闭WiFi低功耗模式，以避免在休眠状态下无法与终端设备进行信令交互导致终端设备接入WiFi热点失败的问题，或者终端设备接入WiFi热点的时延较高的问题。
S504、接入点与终端设备进行关联。
其中，接入点与终端设备进行关联的过程为终端设备接入接入点的WiFi热点的过程。
在接入点与终端设备进行关联的过程中，若终端设备支持WiFi低功耗模式，终端设备将会向接入点发送低功耗支持帧。
S505、若接入点与终端设备关联失败，则接入点开启WiFi低功耗模式。
具体来说，若接入点与终端设备关联失败，则接入点的WiFi热点中仍然没有终端设备接入，此时，接入点开启WiFi低功耗模式，以降低WiFi热点产生的功耗。
S506、若接入点与终端设备关联成功，接入点确定终端设备是否支持WiFi低功耗模式。
具体来说，接入点可以根据是否接收到该终端设备的低功耗支持帧，确定终端设备是否支持WiFi低功耗模式。
S507、在终端设备不支持WiFi低功耗模式的情况下，接入点关闭WiFi低功耗模式。
这样，可以避免接入点开启WiFi低功耗模式后，终端设备在WiFi热点处于休眠状态的情况下向接入点发送数据，导致终端设备的数据包丢失。
S508、在终端设备支持WiFi低功耗模式的情况下，接入点开启WIFI低功耗模式。
S509、接入点保持开启WiFi低功耗模式，直至接收到新的WiFi热点接入请求。
在此之后，终端设备执行以上S502-S507，确定是否开启WiFi低功耗模式。
也即是说，在接入点开启WiFi低功耗模式的情况下，若存在新的终端设备请求接入WiFi热点，则接入点关闭WiFi低功耗模式，与新的终端设备进行关联，并根据关联结果以及新的终端设备是否支持WiFi低功耗模式确定是否开启WiFi低功耗模式。
S510、若存在终端设备与接入点的WiFi热点断开连接、接入点确定是否存在终端设备接入WiFi热点。
接入点确定存在终端设备断开与WiFi热点的连接之后，确定是否继续开启WiFi低功耗模式。
S511、若是，则接入点保持开启WiFi低功耗模式。
S512、若否，则接入点保持关闭WiFi低功耗模式。
一种可能的实现方式中，接入点在开启WiFi低功耗模式的情况下，可以显示第一标识。第一标识用于表征接入点开启了WiFi低功耗模式。
如图6所示，为第一标识的一种示意图。如图7所示，为接入点显示第一标识的界面示意图。第一标识包括第一图标和第二图标，第一图标为WiFi热点图标，第二图标为WiFi低功耗模式图标。
具体来说，接入点的WiFi芯片执行以上S500-S509中的一个或多个步骤之后，WiFi芯片确定是否开启WIFI低功耗模式。若WiFi芯片确定开启WiFi低功耗模式，则生成第四指示信息。WiFi芯片向SOC芯片发送第四指示信息。第四指示信息用于指示接入点显示第一标识。
SOC芯片接收到第四指示信息之后，指示接入点显示第一标识。
一种示例，SOC芯片调用接入点的UI界面，并在接入点的UI界面上显示第一标识。
又一种可能的实现方式中，接入点在关闭WiFi低功耗模式的情况下，可以显示第二标识。第二标识用于表征接入点关闭了WiFi低功耗模式。
如图8所示，为第二标识的一种示意图。如图9所示，为接入点显示第二标识的界面示意图。第二标识包括第一图标，第一图标为WiFi热点图标。
具体来说，接入点的WiFi芯片执行以上S500-S509中的一个或多个步骤之后，WiFi芯片确定是否开启WiFi低功耗模式。若WiFi芯片确定关闭WiFi低功耗模式，则生成第五指示信息。WiFi芯片向SOC芯片发送第五指示信息。第五指示信息用于指示接入点显示第二标识。
SOC芯片接收到第五指示信息之后，指示接入点显示第二标识。
一种示例，SOC芯片调用接入点的UI界面，并在接入点的UI界面上显示第二标识。
基于上述技术方案，接入点可以根据是否开启了WiFi低功耗模式，在UI界面上显示相应的标识。这样，可以便于用于根据接入点显示的标识直观的确定接入点的WiFi热点的状态。
