物联网终端，一般包含主控模块和通信模块。现有技术中，当物联网终端正常工作时，主控模块进行数据处理，通信模块通过高速通信链路从路由器获取数据并将数据发送给主控模块，或者是通过高速通信链路将主控模块处理后的数据发送给路由器。

本申请实施例提供了一种待机控制方法，用于降低终端待机时的功耗。
请参阅图1，为终端待机模式示意图。在常见的终端待机方法中，终端通过网络通信模块与路由器连接进行通信。终端主要包括主控中央处理器(central processing unit，CPU)和网络通信模块，当终端待机时，主控CPU处于下电状态，而网络通信模块与路由器保持心跳连接，可以支持快速联网和远程唤醒。由于终端待机时，网络通信模块与路由器保持心跳连接，功耗较高。
请参阅图2，本申请实施例中终端联网架构图。该架构可以用于终端视频数据传输等场景。本申请实施例中终端联网架构中增加了中继设备，终端通过中继设备与路由器进行通信连接，终端通过中继设备、路由器与云端进行通信连接。
终端组成结构主要包括主控CPU、无线保真(wireless fidelity，WiFi)模组、微控制单元(microcontroller unit，MCU)和电源管理单元(power management unit，PMU)，以及射频(radio frequency,RF)模组。本申请实施例中终端结构中增加了RF模组。
示例性的，主控CPU，例如可以是摄像头CPU、机顶盒CPU，负责运行媒体业务，如登录业务，推送业务和点播业务等；可选的，主控CPU可以包括如下至少一种类型：通用中央处理器、数字信号处理器(digital signal processor，DSP)、微处理器、微控制器(microcontroller unit，MCU)、或微处理器。例如，主控CPU可以是一个单核(single-CPU)处理器或多核(multi-CPU)处理器。或者该主控CPU可以是多个处理器构成的处理器组，多个处理器之间通过一个或多个总线彼此耦合。该主控CPU可以包括模拟-数字转换器(analog-to-digital converter，ADC)、数字-模拟转换器(digital-to-analog converter，DAC)以实现装置不同部件之间信号的连接。MCU用于电源控制和外部事件检测；PMU能为主控CPU及终端各组成模块提供电源；WIFI模组即高速通信模块还可以是第四代移动通信技术(the 4th generation mobile communication technology，4G)无线模块等，WIFI模组用于进行业务通信；示例性的，网络通信模块可以包括中央处理器CPU或微控制器MCU、射频收发器(也可以称作是射频电路)。
RF模组为唤醒模块，例如可以是蓝牙模块等，RF模组用于在终端待机模式下向中继设备发送保活报文从而与中继设备保持心跳连接，还可以接受中继设备发送的唤醒报文，将待机模式下的终端唤醒。RF模组的功耗低于WIFI模组的功耗，该RF模组功耗低的原因可以是：监听的频点的带宽窄，承载的数据量小，因此需要的能耗低；协议简单，芯片逻辑处理简单，功耗低。需要说明的是，终端RF模组可以集成在终端中；或作为外接硬件单独存在，应当理解，当终端RF模组作为单独存在的外接硬件时，在一种可选的情况中，终端RF模组可以通过串行外设接口(serial peripheral interface，SPI)与终端连接。
中继设备的组成结构主要包括主控CPU、WIFI模组、MCU以及RF模组。
中继设备结构中还设有中继设备代理模块，代理模块可以集成在中继设备WIFI模组中实现，也可以在中继设备WIFI模组之外的其他模块中实现。中继设备代理模块的功能包括云端 服务保活、终端远程唤醒和终端IP地址、路由器DHCP续约等。
中继设备主控CPU可用于负责运行媒体业务WIFI模组即网络通信模块为高速通信模块，还可以是4G无线模块等，WIFI模组用于与终端进行业务通信；RF模组为唤醒模块，还可以是蓝牙模块等，RF模组用于在终端待机模式时与终端保持心跳连接，和在远程唤醒终端时向终端RF模组发送唤醒报文。需要说明的是，中继设备RF模组可以集成在中继设备中；或作为外接硬件单独存在，应当理解，当中继设备RF模组作为单独存在的外接硬件时，在一种可选的情况中，中继设备RF模组可以并通过串行外设接口与中继设备连接。
应当理解，终端设备和中继设备的WIFI模组中均包含RF模块，WIFI模组中的RF模块单位时间内传输的数据量大，在一种可选的情况中，WIFI模组中的RF模块单位时间内传输的数据量大于10M；而起到唤醒作用的RF模块单位时间内可传输的数据量小，在一种可选的情况中，起唤醒作用的RF模块单位时间内传输的数据量小于1M。
在本申请实施例的终端联网架构下，终端正常业务模式时，主控CPU与WIFI模组均为上电状态，终端通过WIFI模组基于第一通信链路与路由器和云端进行连接通信，RF模组待机或下电。当终端进入待机模式时，终端主控CPU下电，WIFI模组关闭大部分功能模块的供电，示例性的，网络通信模块关闭射频模块停止收发数据，仅保存部分模块的供电以维持内存刷新，终端通过RF模组基于第二通信链路与中继设备保持心跳连接，并通过中继设备保持与云端的连接，此时，WIFI模组处于超低功耗模式。由于RF模组的功耗较WIFI模组的功耗低，相较现有技术中终端通过WIFI模组进行心跳连接，终端待机功耗降低。在一种可选的情况中，第一通信链路为无线WIFI通信链路，传输速率高，第二通信链路为RF通讯链路，传输速率低，相比于第一通信链路，第二通信链路对应新的空口、基于简单的数据协议，示例性的，简单的数据协议体现在：载波的复杂度低、协议传输本身的复杂度低。

中继设备网络通信模块可以包括业务层、OS层、驱动层和硬件层；驱动层为硬件层的接口，OS层只有通过驱动层才能控制硬件设备的工作。
其中，中继设备业务层的HOSTAPD可以完成待机控制方法中的两个功能：1)从网络通信模块获取信道和设备IP参数2)设置设备在线不超时；云端保活代理：可代理终端设备向中继设备发送第一保活报文；动态主机配置协议(dynamic host configuration protocol，DHCP)代理：中继设备通过向路由器发送DCHP续约报文，用于IP地址续约租期；免费地址解析协议(address resolution protocol，ARP)代理：向路由器发送ARP报文等与路由器保持连接，防止路由器ARP表老化。OS层的RTOS为实时操作系统。

中继设备的网络通信模块和唤醒模块可以通过以上分层模型实现本申请实施例中待机控制的方法，中继设备执行的具体步骤请参见附图6对应的实施例。
基于图2所示的终端联网架构图，下面对本申请实施例提供的一种待机控制的方法进行说明，请参阅图5，为本申请实施例中待机控制方法的一个交互流程图。
终端设备的进入待机模式时，主控CPU下电、网络通信模块(例如可以是WIFI模组高速通信模块)关闭用于进行高速数据传输的RF模块并停止收发数据，只保留很少的供电以维持WIFI模组的内存刷新，由低速通信的RF模组替代高速通信的WIFI模组通过低速通信链路向中继设备定期发送保活报文，从而通过中继设备与云端服务器保持心跳连接。因此，终端设备在进入待机模式之前，需要与中继设备协商保活所需的准备工作。
该待机控制的方法具体包括：
步骤1、终端设备接收待机指令后将进入待机模式，通过第一通信链路向中继设备发送第一通知信息，该第一通知信息用于通知中继设备在终端设备进入待机模式之后，由中继设备代理终端设备向云端服务器发送第一保活报文，以告知云端服务器终端设备还存活。可选的，保活报文还可以称作心跳包，应当理解，心跳一般是指通信双方的某一端向另一端发送自定义指令，以判断双方是否存活，而且通常会按照一定间隔发送，类似于心跳，因此还被称为心跳指令。
示例性的，该第一通信链路为终端设备的WIFI模组高速通信模块与中继设备的WIFI模 组高速通信模块之间的无线WIFI通信链路，第一通信链路为高速通信链路，当终端设备处于正常业务模式时，通过第一通信链路与云端服务器进行业务和数据通信。示例性的，中继设备通过向路由器发送DHCP续约报文和ARP报文等与路由器保持连接，并借由路由器进一步与云端服务器保持连接。其中，DHCP续约报文可用于IP地址续约租期，免费ARP报文用于防止路由器ARP表老化。在一种可选的情况中，中继设备向路由器发送DHCP续约报文和免费ARP报文的动作是周期性发送的，该发送周期可以为30秒至60秒，由于始终发送保活报文过于浪费资源提升系统功耗，本申请实施例通过周期性发送保活报文既可以确保中继设备与云端服务器保持连接，又合理降低了系统功耗。应当理解，路由器存在老化周期，每超过老化周期路由器中存储的关于终端设备的特征信息(例如ARP表、NAT表等)就会清除，为了避免路由器老化，中继设备给路由器发送DHCP续约报文和免费ARP报文的周期要小于路由器的老化周期，本申请实施例对中继设备向路由器发送报文的周期不作具体限定。
示例性的，中继设备代理终端设备向云端服务器发送云端保活报文，使得云端服务器认为终端与云端服务器处于连接状态。可选的，中继设备发送云端保活报文的周期可以为30秒至60秒。
步骤2、终端设备通过第一通信链路与中继设备协商待机参数和唤醒参数等。
示例性的，待机参数包括终端设备待机期间中继设备向终端设备发送终端保活报文的周期，可选的，保活报文还可以称为心跳包；示例性的，待机期间中继设备向终端设备发送终端保活报文的周期可以为5秒至10秒，但是本申请实施例对心跳周期的具体数值不作具体限定。
示例性的，唤醒参数可以包括唤醒随机码、唤醒随机数等参数，唤醒随机数为终端从待机状态被唤醒时的验证随机数，终端通过验证唤醒随机数可提高唤醒过程的安全性。
步骤3、终端设备通过第一通信链路向中继设备发送第二通知信息，该第二通知信息用于通知中继设备终端设备将关闭用于高速传输的WIFI模组中的RF模块，中继设备开启允许设备在线不超时功能，即中继设备不限定终端设备的在线时长，并与终端设备保持在网络通信的连接状态。其中，在线不超时功能可以理解为中继设备设置相关参数，即使超过预设时限未进行业务通信，也不判定终端设备为下线状态。
步骤4、终端设备关闭用于高速传输的WIFI模组中的RF模块。
应当理解，当终端设备处于正常业务模式时，由高速传输的WIFI模组完成数据和信息传输在内的网络通信功能，WIFI模组内部包含MCU、RF发送器、RF接收器等，当终端设备进入待机模式时，为了尽可能降低终端设备的功耗，关闭用于进行高速数据传输的RF模块并停止收发数据，只保留很少的供电以维持WIFI模组的内存刷新，此时终端设备的WIFI模组处于超低功耗模式，在一种可选的情况中，处于超低功耗模式的WIFI模组的工作电流大约只有10微安至20微安。应当理解，超低功耗模式与下电模式不同，由于WIFI模组内存始终在刷新，当有业务需求时终端设备的WIFI模组可以迅速恢复正常业务模式。
步骤5、终端设备下电主控CPU，终端进入待机模式。
步骤6、终端设备通过第二通信链路接受并应答中继设备发送的终端保活报文。
示例性的，终端设备进入待机模式之后，低速通信的RF模组通过第二通信链路接收中继设备发送的终端保活报文，并向中继设备发送应答报文，可选的，终端设备向中继设备发送 的应答报文可以是ACK报文，ACK报文形式简单，通常只占用4个字节或8个字节，而正常的保活报文(例如中继设备发送的云端保活报文和终端保活报文)需要占用十几个字节。应当理解，为了进一步降低终端设备在待机模式下的功耗，由中继设备向终端设备发送保活报文，终端设备只需要发送形式更简单的应答报文即可。即中继设备通过保活报文询问终端设备是否在线，终端设备只需要回答是即可，应答信息更简单，功耗更低。当中继设备收不到终端设备的回应时，则认为终端设备断线，此时中继设备停止向云端服务器发送云端保活报文，终端与云端服务器断开连接。当中继设备收到终端设备的回应时，则中继设备认为终端设备处于在线状态，并通过向云端服务器发送云端保活报文使终端设备与云端服务器保持连接状态。
可选的，中继设备向终端设备发送终端保活报文是周期性发送的，示例性的，该发送周期可以是步骤2中协商得到的。在一种可选的情况中，为了尽可能缩短唤醒终端所需的时间，在有业务需求时使终端尽快恢复到正常业务模式，终端低速RF模组每隔0.5秒至1秒启动一次，以用于接收和应答唤醒报文或保活报文。
在一个可选地情况下，终端在待机状态下，低速RF模组的工作电流为30微安至40微安，显著低于终端通过高速WIFI模组进行心跳保活时的工作电流约为300微安至400微安。
步骤7、云端服务器向中继设备发送第一唤醒报文。
当需要唤醒终端时，云端构建第一唤醒报文并发送给中继设备，第一唤醒报文中携带了待唤醒的终端设备的设备ID，此外，还可以携带唤醒周期，唤醒周期可以由云端确定，用于指示中继设备根据该唤醒周期发送唤醒报文给终端设备，唤醒周期的具体数值此处不做限定。可选的，该唤醒报文经由路由器按照唤醒周期定期发送给中继设备代理模块。
步骤8、中继设备基于接收到的第一唤醒报文构建第二唤醒报文。
中继设备接收到云端发送的唤醒报文后，从唤醒报文中解析获取需要唤醒的终端的设备ID，中继设备根据该设备ID获取终端设备的网络通信的相关参数，在一种可选的情况中，中继设备从WIFI模组高速通信模块的HOSPPAD处获得终端设备的网络通信的相关参数；中继设备基于解析结果构建第二唤醒报文，该第二唤醒报文可以包括设备ID、解析得到的网络通信的相关参数以及之前协商的唤醒特征码和唤醒随机数等，示例性的，网络通信的相关参数可以包括第一通信链路的信道参数、终端设备的地址参数等，该参数可用于终端设备与中继设备快速通过第一通信链路建立通信连接，以恢复正常业务模式。唤醒特征码为预设的用于识别唤醒报文的标识，例如云端可以通过向中继设备发送010101告知中继设备唤醒终端设备，该010101即为唤醒特征码。
步骤9、中继设备通过第二通信链路向终端设备发送第二唤醒报文。
中继设备通过第二通信链路向该设备ID对应的终端唤醒模块发送第二唤醒报文。
步骤10、终端设备接收到第二唤醒报文后，验证第二唤醒报文中携带的唤醒随机数与预设或协商的唤醒随机数是否一致，如果一致，则终端主控CPU上电；如果不一致，则终端仍然处于待机模式。终端开启高速WIFI模组中下电的部分上电，并开启RF模块，进入正常业务模式，可选的，终端设备基于第二唤醒报文中的信道、地址参数与中继设备快速建立通信连接，并恢复通过第一通信链路进行业务通信。
步骤11、终端设备通过第一通信链路向中继设备发送第三通知消息，第三通知消息用于 通知中继设备停止代理终端设备向云端发送保活报文，终端设备进入业务服务模式，例如可以进行登录业务、推送业务和点播业务等业务。

终端在业务服务模式下，可以通过中继设备、路由器与云端进行通信连接。终端通过终端网络通信模块与中继设备网络通信模块之间的第一通信链路传输数据。示例性的，第一通信链路为高速传输链路，传输速率大于10兆每秒。
当终端收到待机指令后，终端主控模块通过该第一通信链路向中继设备代理模块发送通知消息，通知中继设备代理模块进行云端待机保活代理，该云端待机保活代理用于使该终端与云端保持连接状态。
602、中继设备代理模块向云端发送报文；
中继设备代理模块收到终端主控模块发送的通知消息后，开启云端待机保活代理。
需要说明的是，中继设备代理模块位于中继设备中，中继设备代理模块向云端发送报文实际上是由中继设备代理模块通过中继设备网络通信模块向云端发送该报文，可选的，中继代理模块发送的报文经由路由器传送给云端。
本实施例中，云端待机保活代理可以包括以下几个方面：
1、中继设备代理模块通过路由器向云端定期发送保活报文，用于保持终端与云端的连接；
2、中继设备代理模块定期向路由器发送DHCP续约报文和免费ARP报文，保持终端与路由器的连接，其中，DHCP续约报文可用于IP地址续约租期，免费ARP报文用于防止路由器ARP表老化。
其中，中继设备代理模块发送保活报文的周期可以由中继设备与云端通过保活报文协商，发送DHCP续约报文和免费ARP报文的周期可以由中继设备代理模块与路由器协商或者由中继设备代理模块按照预设周期发送，此处对中继设备代理模块发送保活报文、DHCP续约报文和免费ARP报文的周期不作具体限定，示例性的，中继代理模块向云端发送报文的周期可以是30秒至60秒。应当理解，通过设置时间间隔定期发送保活报文是为了降低功耗，设置合适的时间间隔既可以确保中继设备和云端保持连接又合理降低了系统功耗。
603、终端主控模块向中继设备唤醒模块发送通知消息；
终端主控模块通过第一通信链路向中继设备唤醒模块发送待机通知消息。中继设备唤醒模块根据该待机通知消息与终端唤醒模块建立第二通信链路。终端主控模块可以在待机通知消息中携带心跳周期和唤醒随机数，或者，终端主控模块和中继设备唤醒模块通过报文协商心跳周期和唤醒随机数等参数。
其中，心跳周期为终端待机模式时，终端唤醒模块与中继设备唤醒模块之间发送心跳包的周期，在一种可选的情况中，终端唤醒模块与中继唤醒模块发送心跳包的周期可以为5秒 至10秒，但是本申请实施例对心跳周期的具体数值不作具体限定。
唤醒随机数为终端从待机状态被唤醒时的验证随机数，终端通过验证唤醒随机数可提高唤醒过程的安全性。
需要说明的是，步骤601与步骤603之间的执行顺序不做限定，可以先执行步骤601再执行步骤603；也可以先执行步骤603，再执行步骤601。
604、中继设备唤醒模块向中继网络通信模块发送通知消息；
该通知信息用于告知中继网络通信模块，终端将进入待机模式。中继网络通信模块接收中继设备唤醒模块发送的通知消息后，开启允许设备在线不超时功能。其中，在线不超时功能是指中继网络通信模块设置相关参数，保持终端网络通信模块为上线状态，即使超过预设时限未进行业务通信，也不判定终端下线。
605、终端主控模块向终端网络通信模块发送消息；
终端主控模块向终端网络通信模块发送通知消息，用于指示终端网络通信模块进入待机模式。
606、终端网络通信模块进入待机模式；
终端网络通信模块收到终端主控模块发送的通知消息后进入待机模式。
应当理解，处于待机模式的网络通信模块关闭了大部分功能模块的供电，仅保留很少一部分供电用于维持内存刷新。示例性的，处于待机模式的终端网络通信模块关闭射频模块不再发射或接收射频信号，且终端网络通信模块的CPU断电，不再处理通信业务，处于待机模式的终端网络通信模块的功耗很低，在一种可选的情况中，此状态的终端网络通信模块的工作电流大约只有10微安(uA)至20微安(uA)。
但是处于待机模式的终端网络通信模块并没有完全断电，会保留一部分模块处于耗电状态，只维持内存刷新，以便当通信需求出现时，可以迅速恢复正常业务模式。
607、终端主控模块向终端唤醒模块发送通知消息；
终端主控模块向终端唤醒模块发送通知消息，通知终端唤醒模块终端将进入待机模式，终端唤醒模块设置相关参数，使得唤醒模块可以接收和应答中继设备唤醒模块发送的保活报文。
608、终端主控模块下电；
终端主控模块下电，终端进入待机状态。
609、中继设备唤醒模块向终端唤醒模块发送保活报文；
中继设备唤醒模块通过第二通信链路按照协商的心跳周期向终端唤醒模块发送保活报文，中继设备唤醒模块发送保活报文的周期具体不做限定，例如，发送周期可以为0.5秒至1秒，确保终端可以在接到云端的通信需求时及时被唤醒。
需要说明的是，步骤609与步骤604的执行顺序不做具体限定，可以先执行步骤604再执行步骤609，可以先执行步骤609再执行步骤604，或者可以并行执行步骤604与步骤609。
610、终端唤醒模块向中继设备唤醒模块发送应答信息；
终端唤醒模块收到中继设备唤醒模块定期发送的保活报文后，终端唤醒模块将通过第二通信链路向中继设备唤醒模块发送应答信息，中继设备唤醒模块接收到终端唤醒模块发送的应答信息后，可以确认终端与中继设备仍保持连接。在终端待机状态下，终端通过终端唤醒 模块与中继设备唤醒模块进行心跳保活，在一个可选地情况下，终端唤醒模块的工作电流为30微安至40微安，显著低于终端通过网络通信模块进行心跳保活时约为300微安至400微安的工作电流。
611、云端向中继设备代理模块发送唤醒报文；
当需要唤醒终端时，云端构建唤醒报文并发送给中继设备代理模块，唤醒报文中携带了待唤醒的终端的设备ID，此外，还可以携带唤醒周期，唤醒周期可以由云端确定，用于指示中继设备根据该唤醒周期发送唤醒报文给终端，唤醒周期的具体数值此处不做限定。该唤醒报文经由路由器按照唤醒周期定期发送给中继设备代理模块。
612、中继设备代理模块向中继设备唤醒模块发送唤醒消息；
中继设备代理模块接收到云端发送的唤醒报文后，从唤醒报文中解析获取需要唤醒的终端的设备ID，然后给中继设备唤醒模块发送携带设备ID的唤醒消息。
613、中继设备唤醒模块获取中继设备网络通信模块的信道参数；
中继设备唤醒模块接收中继设备网络通信模块发送的携带设备ID信息的唤醒消息，中继设备唤醒模块根据设备ID从中继设备网络通信模块中获取中继设备网络通信模块的信道、地址等参数，该参数为可用于终端网络通信模块与中继设备网络通信模块建立通信连接的相关参数。
614、中继设备唤醒模块向终端唤醒模块发送唤醒报文；
中继设备唤醒模块构建唤醒报文，并通过第二通信链路向该设备ID对应的终端唤醒模块发送唤醒报文，唤醒报文中可以携带中继设备网络通信模块的信道参数，可选地，信道参数可以包括信道、地址等信息，可选地，唤醒报文中还可以携带唤醒特征码和唤醒随机数等。唤醒特征码为预设的用于识别唤醒报文的标识。终端唤醒模块验证唤醒随机数是否与终端主控模块预设或协商确定的唤醒随机数一致，若一致，则终端唤醒模块对终端进行唤醒；若不一致，则终端唤醒模块不对终端进行唤醒。
615、终端唤醒模块唤醒主控模块；
终端唤醒模块接收唤醒报文，并根据唤醒报文唤醒终端主控模块，终端主控模块上电。
616、终端唤醒模块唤醒终端网络通信模块；
终端唤醒模块接收唤醒报文后，可根据唤醒报文唤醒终端网络通信模块，网络通信模块下电部分重新上电，并开启射频模块，进入正常业务模式。可选地，终端唤醒模块向终端网络通信模块发送通知消息，通知消息中可以携带中继设备网络通信模块的信道参数。网络通信模块可以根据该信道参数快速恢复通过第一通信链路进行业务通信。
617、终端主控模块向中继设备网络通信模块发送通知消息；
终端主控模块通过第一通信链路向中继设备网络通信模块发送通知消息，通知中继设备网络通信模块终止终端保活代理，终端进入业务服务模式，可以进行例如登录业务、推送业务和点播业务等业务。
本申请实施例提供的待机控制方法，通过增加终端第二通信模块和中继设备，在在待机模式时，终端第一通信模块进入超低功耗待机模式，终端通过终端第二通信模块与中继设备保持心跳连接。由于终端第二通信模块较终端第一通信模块功耗低，因此，终端待机状态时的功耗降低。
