在本申请的一些实施例中,存储器301可以采用非易失性存储器,随机存取存储器,闪存以及只读存储器,随机存取存储器是在路由器启动或供电间隙时会丢弃其信息,只读存储器保存路由器的启动软件,启动软件是路由器运行的第一个软件,负责路由器进入正常的工作状态,路由器将完整的操作系统作为备用保存在随机存储存储器中,以便在操作系统不能使用时,作为备份使用,只读存储器通常设置在一个或多个芯片上,焊接在路由器的主机板上。闪存的主要用途是存储HiLink路由器30的操作系统,维持路由器的正常工作,如果路由器安装了闪存,则主要用来引导路由器操作系统的默认位置,只要闪存的容量足够,可以保存多个操作系统映像,以提供多重启动选项,其中,HiLink路由器30的操作系统采用Linux操作系统。非易失性存储器的主要作用是保存操作系统启动时读入的配置数据(启动配置)。随机存取存储器主要作为操作系统表和缓冲的存储区,操作系统可以通过随机存取存储器满足所有的常规存储需要,让路由器能迅速访问这些信息,其中,随机存取存储器的存储速度优于以上提到的三种。
处理器302可以包括一个或多个处理单元,例如,可以包括中央处理器CPU(Central Processing Unit)、图像处理器GPU(Graphics Processing Unit)、数字信号处理器(digital signal processing,DSP)、微处理器MCU(Micro-programmed Control Unit)、AI(Artificial Intelligence,人工智能)处理器或可编程逻辑器件FPGA(Field Programmable Gate Array)等的处理模块或处理电路。其中,不同的处理单元可以是独立的器件,也可以集成在一个或多个处理器中。处理器302中可以设置存储单元,用于存储指令和数据。在一些实施例中,处理器302中的存储单元为高速缓冲存储器,其中,HiLink路由器30的处理器302用于控制Hi键点亮,并且针对智能摄像头广播发送的Probe Request,在Probe Response中扩展IE2,以为智能摄像头提供临时的SSID和主接入点的SSID。
HiLink路由器30的接口303都有各自的名称和编号,一个接口的全名称由接口的类型标志与数字编号构成,编号自0开始。对于接口固定的路由器或采用模块化接口的路由器,在接口的全名称中,只采用一个数字,并根据其在路由器的物理顺序进行编号。例如Ethernet0表示第1个以太网接口,Serial1表示第2个串口。对于支持“在线插拔和删除”或具有更改物理接口配置的路由器,其接口全名称中至少包含两个数字,中间用斜杠“/”分割,其中,第1个数字代表插槽编号,第2个数字代表接口卡内的端口编号。对于支持“万用接口处理器”的路由器,其接口编号形式为“插槽/端口适配器/端口号”,如Ethernet4/0/1是4号插槽上第1个端口适配器的第2个以太网接口。
控制台端口304是使得用户或管理员能够利用入网设备与HiLink路由器30进行通讯,完成路由器的配置,该端口提供了一个EIA/TIA-232异步串行接口,用于在HiLink路由器30进行配置。
辅助端口305,辅助端口305与控制台端口304类似,也提供一个EIA/TIA-232异步串行接口,不同的是,其常用于连接调制解调器以实现对路由器的远程管理。
电源模块306可以包括电源、电源管理部件等。电源管理部件用于管理电源的充电和电源向其他模块的供电。
再返回图1所示的场景,下面对图2和图3所示的智能摄像头与HiLink路由器两者之间的配网过程进行说明。
智能摄像头20作为待配网的智能家居在出厂设置的状态下时被设置成AP模式,在AP模式下通过自身的无线通信模块204主动在全信道上广播发送探测请求(Probe Request),并在广播发送的Probe Request中扩展自定义信息元素IE 1。HiLink路由器30搜索到带有自定义信息元素IE 1的Probe Request后,解析Probe Request,向智能摄像头20回复一个Probe Response,首次回复的Probe Response仅仅是用于通知待配网的智能摄像头设备有设备发现了它,同意与待配网的智能摄像头设备进行配网。同时HiLink路由器30通过点亮HiLink路由器30的Hi键提示用户触发Hi键进行配网。其中,自定义信息元素IE 1中包含智能摄像头20的设备ID(可以是生产编号)和智能摄像头20的设备基本信息(如型号/版本、生产厂商、设备名称等)。
用户触发Hi键后,HiLink路由器30开始配网,路由器开放临时的SSID,并对智能摄像头20广播发送的Probe Request进行回复,在探测回复(Probe Response)中自定义扩展IE 2,在IE2中携带临时的SSID。其中,自定义信息元素IE 2中包含有路由器30智能摄像头20分配的临时的SSID和信道。
智能摄像头20接收到HiLink路由器30反馈的扩展有IE 2的Probe Response之后,切换到STA模式,并解析Probe Response中的IE 2携带的临时的SSID并通过临时的SSID接入临时网络和指定信道。HiLink路由器30通过临时的SSID向智能摄像头20传输HiLink路由器30的主接入点的SSID和密码,智能摄像头20接收到HiLink路由器30的主接入点的SSID和密码后,通过路由器的主接入点的SSID和密码接入HiLink路由器30的主接入点的网络,完成与HiLink路由器30的配网,最后再断开临时网络。
IE(Information Element)是在Probe Request或者Probe Response中扩展的数据片段。在本申请的一些实施例中,扩展IE包括扩展IE1和扩展IE2,扩展IE 1和扩展IE 2的字 段格式如下:

Vendor specific type用于标识特定的自定义类型。其中,本申请中,特定的自定义类型可以用来标记这个扩展IE 1和扩展IE 2是用于SOFT AP配网的,路由器30通过Vendor specific type判断智能摄像头20发出的探测请求是否是与路由器30进行配网的配网请求。例如将扩展IE1和扩展IE2中的Vendor specific type定义为19,即标识Probe Request或者Probe Response是路由器30和智能摄像头20用于SOFT AP配网的。
具体的,HiLink路由器30收到智能摄像头20发送的携带有扩展IE 1的之后,读出Vendor specific type的字段,如果Vendor specific type字段为19,说明此时智能摄像头20的发出的Probe Request是用于与路由器30进行SOFT AP配网的请求。则允许智能摄像头20进行配网)。并继续解析Vendor specific type字段之后的Data。如果Vendor specifictype的字段不是19,说明此时智能摄像头20发送的Probe Request并不是与路由器30进行配网的配网请求,根据本申请中的一些实施例,可以直接丢弃该Probe Request或者实现该Probe Request的其余的功能。
Data用于标识扩展的数据。其中,对于扩展IE1而言,扩展的数据至少可以包括:智能摄像头20的设备ID和智能摄像头20的设备基本信息(如设备类型、型号、版本、生产厂商、设备名称等)。示例性的,某款AI摄像头的设备ID可以为“101q”。其中,设备类型指的是该设备所属的类型,如智能摄像头20属于摄像头一类,其设备类型可以表示为“027”、HiLink路由器30属于路由器类,其设备类型可以表示为“1”、华为手机P30属于手机类,其设备类型可以表示为“14”。对于扩展IE2而言,扩展的数据至少可以包括:路由器30为待配网设备分配的临时的SSID和信道。

通过以上编号“1”、字节长“4”、设备ID的ASCII以及编号“2”、字节长“3”、设备类型的ASCII得到扩展IE1的Data为0x0104313031710203303237。其中,“0x”表示的是十六进制。扩展IE1的Data的字节数为11字节。
当然扩展IE1的字段格式也可以设置为其他的格式,扩展IE1的Data除了可以携带设备的ID和设备类型外,也可以携带设备名称(如AI摄像头)、设备的生产编号等其他的信息。本申请实施例在此均不作限定。
接下来,以HiLink路由器30为WS5200四核版为例对Probe Response和Probe Response中携带的扩展IE2的字段格式进行说明。HiLink路由器30为WS5200四核版的生产厂商为00-E0-FC(如指代华为生产厂商),设备型号为WS5200,设备ID为100005625634。
对于携带扩展IE2的Probe Response而言,扩展IE2的Data至少可以携带HiLink路由器30为智能摄像头分配的临时的SSID和指定信道号。如临时的SSID可以为智能摄像头和路由器当前SoftAP的SSID字符串,如“TEST-SOFTAP”,指定信道号可以为智能摄像头和路由器当前SoftAP所在信道编号“11”。

其中,Tag number可以定义为十六进制0xDD,即十进制221。Length定义的数据长度可以为0X10。OUI定义的生产厂商为00-E0-FC(路由器的生产厂商提供)。定义Vendor specific type携带扩展IE 2进行SOFT AP配网的标识为0X13。扩展IE2的Data具体如下表二所示:
表二
Figure PCTCN2021108191-appb-000005
表一中,不同的编号T标识的是IE2携带的数据的不同类型,如定义不同的编号T标识IE2携带的数据类型为临时SSID或指定信道号或其他信息,其占用1字节。字节长L表示的是临时SSID或指定信道号或其他信息的字符串所占用的字节数,其占用1字节。V表示的是临时SSID的ASCII或指定信道号的ASCII或其他信息的ASCII。

扩展IE2的Data携带HiLink路由器30除了可以携带SSID和指定信道之外,还可以携带HiLink路由器30的设备信息,如设备ID、型号、设备名称等。
值得注意的是,对于Tag number、Vendor specific type还可以定义为其他的标识,本申请实施例在此并不作限定。对于扩展IE1和扩展IE2的字段格式以及携带的内容,除了本申请实施例提到的以上信息外,还可以携带其他的信息,本申请实施例在此也不作限定。
以下通过与现有技术中传统的智能家居与路由器进行配网的方法的比较,来说明本 申请的以智能摄像头为例的智能家居和以HiLink路由器为例的路由器之间进行配网的方法的效果。
图4(a)为一种实现方式中的智能家居组播配网的配网流程示意图,图4(b)为另一种实现方式中的智能家居通过无线软AP的方式进行配网的流程示意图。
目前,智能家居与路由器之间进行配网的配网方式可以分为组播配网和无线软接入点(Soft-Access Point,Soft-AP)配网。如图4(a)所示的,待配网的智能家居在WiFi信标(Beacon)帧里扩展数据片段(Information Element,IE)并自动组播,路由器通过检测IE发现待配网设备,并通知用户触发组网。其中,本申请提供的一种实现方式中,IE的Date中携带了待配网的智能家居ID和标识待配网的智能家居进行联网的特定的SSID(如huaweiet)。路由器通过检测待配网的智能家居IE中携带的设备ID和特定的SSID发现待配网设备。IE中的Vendor specific type中携带用于待配网的智能家居进行组播配网的标识以使路由器识别待配网的智能家居需要进行组播配网。
通知用户触发组网的方式可以是路由器点亮自身的指示灯。用户可以通过触发路由器的Hi键、WPS按键等触发路由器组网。
用户触发路由器进行组网之后,由路由器通过组播报文向待配网的智能家居发送配网信息,待配网的智能家居扫描到组播报文之后并解析组播报文完成配网。其中,组播报文中携带了路由器为待配网的智能家居分配的AP的SSID和接入密码。SSID是路由器所在的局域网的名称。待配网的智能家居通过该接入密码和SSID接入路由器所提供的局域网。
采用组播配网的方式必须由待配网设备全信道(全信道指的是待配网设备和路由器在组播配网时的所有的信道)监听组播报文,在某一个信道监听到组播报文之后,立即停留在该信道并作为固定信道。停留在该信道后,路由器和待配网设备之间通过固定信道进行数据交互。但是组播配网的方式很容易受到恶意攻击且是单向组播,组播报文是在全信道广播,任何设备想要加入路由器和待配网设备的组播网络时,只需要将设备自身的IP地址改为网络的组播地址即可。组播配网的方式其安全性较低,因此组播配网的方式逐渐被淘汰。
如图4(b)所示的,待配网的智能家居通过SOFT AP的方式进行配网逐渐成为一种主流的方式。待配网的智能家居通过SOFT AP的方式进行配网时,必须在手机或电脑上安装SOFT AP的应用程序(APP),通过手机或电脑的APP实现待配网的智能家居与路由器的配网。具体为待配网的智能家居在出厂态时进入AP模式,由待配网的智能家居广播待配网设备的AP的SSID,手机或电脑上安装的SOFT AP的APP通过扫描待配网智能家居的AP的SSID连接到待配网智能家居,通过待配网智能家居自身的网络向待配网设备加密传输路由器的SSID和密码,待配网的智能家居通过待配网的智能家居的SSID接收手机或电脑传输的路由器的SSID和密码,并进行解密。此时,手机或电脑再断开与待配网的智能家居的AP的SSID连接,重新接回到手机或电脑原来的网络。待配网的智能家居通过解密后的路由器的SSID接入路由器的网络完成配网。采用SOFT AP的方式进行配网时,需要通过第三方手机或电脑的协助完成待配网的智能家居与路由器的配网,配网的操作繁琐。此外,通过手机或电脑为待配网的智能家居进行配网时,需 要手机和电脑切换其当前接入的网络至待配网的智能家居所广播的网络,因部分手机或电脑存在兼容性的问题,很容易导致配网失败,因此该种配网方式的配网易用性差。此外,在手机和电脑配网完成之后,经常会出现手机不能回连到原来的网络,导致用户的体验感较低。
通过本申请实施例公开的配网方法,智能摄像头在Probe Request中扩展IE 1,HiLink路由器针对Probe Request向智能摄像头反馈一个携带有扩展IE 2的Probe Response,智能摄像头通过扩展IE2中携带的临时的SSID和密码(临时的SSID和密码作为临时联网数据)接入临时网络(作为第一连接),并由HiLink路由器通过临时网络向智能摄像头传输HiLink路由器的主接入点的SSID和密码(主接入点的SSID和密码作为配网数据),智能摄像头通过主接入点的SSID和密码接入HiLink路由器的主接入点的网络完成配网(作为第二连接)。一方面,通过本申请实施例提供的配网方法,仅需用户触发Hi键便可启动配网流程,无需通过操作手机上的应用程序便可实现HiLink路由器30与智能摄像头20之间的配网,操作简单,配网可靠性高。另一方面,本申请实施例中智能摄像头20和HiLink路由器30之间配网时,本申请中HiLink路由器通过Probe Response携带的临时的SSID向智能摄像头反馈主接入点的SSID和密码,其安全性更高。
以下结合附图,对根据本申请的具体实施方式的HiLink路由器发现待配网的智能摄像头的方法进行进一步介绍。
请参见图5,图5为本申请实施例公开的一种HiLink路由器发现待配网的智能摄像头,并和待配网智能摄像头完成配网的线程示意图。
下面基于附图5描述以HiLink路由器为例的路由器(第二电子设备)和待配网的智能摄像头(第一电子设备)的配网的详细步骤:
S50:待配网的智能摄像头设备在出厂设置的状态下处于AP模式。待配网的智能摄像头设备进入AP模式后,以全时广播的方式持续不间断的在全信道自动广播扩展携带有扩展字段一(Information Element1,IE1)的探测请求(Probe Request)作为第二探测请求。其中,扩展IE1用于智能摄像头广播自身的设备信息,扩展IE 1中包含的设备信息包括待配网的智能摄像头的设备基本信息(如设备ID、设备类型、型号、版本、生产厂商、设备名称等),如此,位于同一本地网络下的各个设备可以发现待配网的智能摄像头设备。扩展IE1的字段格式可以参加以上实施例的描述。
进一步,待配网的智能摄像头设备也可以不采用全时广播的方式,而是定时的在全信道自动广播扩展有扩展IE 1的Probe Request,其可以以5秒或10秒为一时间间隔定时在全信道自动广播扩展有扩展IE 1的Probe Request。
S51:路由器(可以是HiLink路由器)接收到Probe Request后,搜索到带有自定义信息元素扩展IE 1的Probe Request,以确定智能摄像头的存在。作为回应,HiLink路由器在HiLink路由器自身的固定信道向待配网的智能摄像头设备发送针对探测请求的反馈第二探测响应Probe Response,这里第二探测响应Probe Response仅仅是通知待配网的智能摄像头设备有设备发现了它,同意待配网的智能摄像头设备进入配网。
S52:路由器(可以是HiLink路由器)接收到Probe Request后,解析携带有自定义信息元素扩展IE 1的Probe Request,通过解析扩展IE 1确定该Probe Request是否为与 HiLink路由器进行配网的配网请求,如果该Probe Request是与路由器进行配网的配网请求,则说明路由器可以和待配网的智能摄像头设备进行配网。此时点亮路由器的指示灯或按键等以提示用户触发按键进行配网。如点亮HiLink路由器的Hi键以提示用户触发Hi键进行配网。其中,点亮HiLink路由器的Hi键具体是使得Hi键亮灯的方式提醒用户。
对于该Probe Request是否为与HiLink路由器进行配网的配网请求具体如下:
示例性的,以上描述的Vendor specific type用于标识特定的自定义类型。其中,特定的自定义类型用来标记这个扩展IE 1和IE 2是用于SOFT AP配网的,路由器通过Probe Request中的Vendor specific type字段的标识判断该Probe Request是否为用于SOFT AP配网的配网请求。例如将IE1中的Vendor specific type定义为19(十进制)即标识其用于与路由器进行SOFT AP配网。HiLink路由器收到智能摄像头发送的携带有扩展IE 1的Probe Request之后,读出Vendor specific type的字段。如果Vendor specific type的字段为19,说明此时的Probe Request是用于和路由器进行SOFT AP配网的配网请求。
值得注意的是,S51和S52可以同步进行,也可以先执行S52,再执行S51。本申请实施例对于S51和S52的顺序并不作限定。
另外,除了可以通过点亮Hi键的方式提醒用户外,还可以通过路由器的指示灯闪烁、语音等方式提醒用户。本申请实施例在此并不作限定。
S53:用户触发Hi键。
S54:路由器(可以是HiLink路由器)的Hi键被触发后,HiLink路由器开始与智能摄像头配网,待配网的智能摄像头设备在AP模式仍以全时广播的方式持续不间断的在全信道自动广播扩展有扩展IE 1的Probe Request作为第一探测响应。
可以理解的是,HiLink路由器的Hi键被触发前扩展有IE 1的Probe Request,和HiLink路由器的Hi键被触发后扩展有扩展IE 1的Probe Request的内容可以相同。当然,Hi键被触发前扩展有IE 1的Probe Request,和HiLink路由器的Hi键被触发后扩展有扩展IE 1的Probe Request的内容也可以不相同。如Hi键被触发前扩展有IE 1的Probe Request可以携带设备ID、设备类型;扩展Hi键被触发后扩展有IE 1的Probe Request可以携带设备ID、设备类型、设备型号等。本申请实施例在此并不作限定。
S55:路由器(可以是HiLink路由器)再次搜索到带有自定义信息元素扩展IE 1的Probe Request(第一探测请求),并向待配网的智能摄像头设备发送针对Probe Request的反馈携带有扩展字段二(Information Element1,IE2)的Probe Response作为第一探测响应。其中,扩展IE 2中包含SOFT AP的临时的SSID(作为第一SSID)和指定信道,临时的SSID将作为隔离的网络,只用于HiLink路由器30和待配网的智能摄像头设备之间通过指定信道进行通讯,而无法通过外网连接访问。临时的SSID用于待配网的智能摄像头和路由器之间通过指定信道进行通信。
隔离的网络指的是临时的SSID的局域网仅用于给HiLink路由器和待配网的智能摄像头设备之间配网使用。在HiLink路由器发现待配网的智能摄像头之后,进行后续配网。扩展IE2的字段格式可以参加以上实施例的描述。
S56:待配网的智能摄像头设备接收到扩展有扩展IE2的Probe Response(第二探测响应),待配网的智能摄像头设备由AP模式切换到STA模式,并连接到HiLink路由器 分配的临时的SSID和指定信道。
S57:待配网的智能摄像头设备连接到临时的SSID和指定信道,并获取到临时的SSID的IP地址。IP地址用于智能摄像头设备接入路由器。待配网的智能摄像头基于IP地址与路由器进行以下步骤S58的IP层安全协商。
S58:路由器(可以是HiLink路由器)和待配网的智能摄像头设备进行IP层安全协商。然后HiLink路由器通过临时的SSID向待配网的智能摄像头设备加密传输主接入点的SSID和密码。
S59:待配网的智能摄像头设备接收主接入点的SSID(作为第二SSID)和密码并解密。通过解密得到的主接入点的SSID和密码连接到HiLink路由器的主AP完成配网。
S60:路由器关闭临时的SSID。
值得注意的是,也可以在执行步骤S50、步骤S51和步骤S52之后直接执行步骤S55至步骤S60。或者执行步骤S50、步骤S51和步骤S52之后直接执行步骤S58至步骤S60。本申请实施例在此并不作限定。
在本申请的一些实施例中,对于图5中S58中的HiLink路由器和待配网的智能摄像头设备进行IP层的安全协商,即对主接入点的SSID和密码进行加密。在待配网的智能摄像头设备按照S50至S57的方式接入到HiLink路由器分配的临时SSID后,需要对对主接入点的SSID和密码进行加密,对于IP层的安全协商和对SSID和密码进行加密的方式,本申请实施例中可以采用个人识别码(Personal Identification Number,PIN)加基于口令的指数密钥交换协议(simple password exponential key exchangeSPEKE)进行加密。在待配网的智能摄像头设备接收到加密的SSID和密码后,再基于PIN加SPEKE的方式对加密的SSID和密码进行解密。此外,对SSID和密码进行加解密的方式还可以是高级加密标准(Advanced Encryption Standard,AES)128加密算法对SSID和密码进行加密。再基于AES128对加密后的SSID和密码进行解密。此外,对SSID和密码进行加解密的方式还可以是其他类型,本申请实施例在此并不作限定。
通过本申请实施例的技术方案,在待配网的智能摄像头设备进入AP模式后,能继续在全信道自动广播扩展有扩展IE 1的Probe Request。路由器搜索到携带有扩展IE 1的Probe Request后,向待配网的智能摄像头设备反馈携带有扩展IE2的Probe Response。待配网的智能摄像头设备切换到STA模式并通过扩展IE2中携带的HiLink路由器分配的临时的SSID和密码接入临时网络。智能摄像头接入临时网络后,HiLink路由器通过临时网络向智能摄像头传输HiLink路由器的主接入点的SSID和密码。智能摄像头断开临时网络并通过主接入点的SSID和密码接入HiLink路由器的主接入点的网络完成配网。一方面,仅需用户触发Hi键便可启动配网流程,无需通过操作手机上的应用程序便可实现HiLink路由器与智能摄像头之间的配网,操作简单,无需切换网络,易用性好。另一方面,本申请实施例中,本申请中HiLink路由器通过携带有扩展IE2的Probe Response携带的临时的SSID建立的临时网络向智能摄像头反馈主接入点的SSID和密码。即HiLink路由器向待配网的智能摄像头传输主接入点的SSID和密码时,由临时网络所提供的指定信道实现HiLink路由器和智能摄像头之间的配网。不会影响智能摄像头和路由器的主接入点的网络安全,因此安全性更高。
