Description

一种设备之间组网的方法和设备

技术领域
本发明涉及通信领域,尤指一种设备之间组网的方法和设备。
背景技术
随着物联网与智能家居的兴起,多个设备的互联互通已经成为了各个产品重要的卖点之一。为此华为公司推出了HiLink连接协议,用于解决不同厂家、不同设备之间的互联互通问题。
互联互通的第一步是组网,但是在通过手机应用(App)进行设备添加(组网)的时候,由于需要手机自动重连指定SSID(某一个路由器的SSID),存在比较多的问题。
现有的HiLink连接协议提供了一种设备之间组网的方法如附图1所示。所述方法包括:
Step1:用户手机C连接主路由A以获得WiFi连接,从主路由A获得主路由A扫描到的周围可以组网的设备B的信息,用户在用户手机C上点击某按钮,确认添加B设备到用户手机C和主路由A所建立的WiFi网络;
Step2:用户手机C自动连接待添加设备B,并将主路由A的SSID和密码发送给设备B;
Step3:设备B收到路由器A的SSID和密码后,去连接主路由器A。
Step4:用户手机C重新连回到主路由A上,以重新获得WiFi连接(目的是不让用户感知到WiFi连接的断开重连)
该方法存在的问题包括以下中的一个或多个:
1、添加设备所耗的时间长
由于需要手机两次进行WiFi连接,消耗的时间较长。
2、可靠性低
WiFi重连依赖于路由和终端设备连接的稳定性,有失败的可能,且容易连错。

现有的HiLink连接协议提供的设备添加(或称设备之间进行组网)方案由于需要用户进行两次WiFi连接,带来了很多问题。
本发明提供的实施例用于解决设备通过无线终端进行组网时的性能以及成功率问题,取消了WiFi重连,通过主路由A直接给待添加设备B发送消息,待添加设备B收到消息后,主动去连接主路由A,使得设备之间的组网变得简单而高效。
本发明提供的一个方法实施例如图2所示,用户手机C、主路由A和设备B可以均具有wifi通信接口。所述方法可以包括:
Step1:用户手机C连接主路由A(即,用于进行拨号上网的路由器A),与所述主路由A组成一个Wifi网络,并且从主路由A获得主路由A扫描到的周围可以组网的设备B(如,具有wifi通信接口并且可以充当副路由的设备)的信息,用户在用户手机C上点击某按钮(如在用户手机C屏幕界面上显示的图标形式的按钮),确认添加设备B(即,确认将设备B添加到手机C和主路由A所组成的WiFi网络中),用户手机C将待添加的设备B的信息(如设备B的SSID(Service Set Identifier,服务集标识)或其他能标识所述设备B的信息)携带在第一消息中发送给主路由A。其中,主路由是需要进行拨号上网的路由器,副路由不需要进行拨号上网,主路由和副路由之间可以是采用桥接模式与对方建立连接。
Step2:主路由A收到手机C发送的第一消息后,获取到待添加设备B的SSID,并向此SSID发送第二消息(第二消息中需要包含路由器A的SSID和密码,至少所述密码需要被加密),通知B来连接自己(主路由器A)。
Step3:设备B收到主路由A的SSID和密码后,去连接主路由器A,从而设备添加完成,所述设备B被成功添加到所述手机C和主路由A所组成的WiFi网络中。
其中Step2,主路由A向待添加设备B发送自己的SSID和密码。这一步骤的实现可以有如下两种可选的方案。
可选方案一:
采用Probe Request Frame和Probe Response Frame的方式。
具体过程如下:
1、主路由器A向待添加设备B发送探测请求帧(Probe Request Frame),其中在Request information中添加标记,表示A向B请求B的公钥。Probe Request Frame的格式如下表1所示(IEEE std 802.11-2007 P84):
表1
Figure PCTCN2016113850-appb-000001
2、待添加设备B收到请求后,向主路由A发送探测响应帧(Probe Response Frame),其中,Requested information elements(被请求的信息元素)中携带B的公钥。Probe Response Frame的格式如下表2所示(IEEE std 802.11-2007 P85):
表2
Figure PCTCN2016113850-appb-000002
3、主路由A使用第二步获取到的B的公钥,对自己的SSID和密码进行加密(至少所述SSID需被加密),并将加密后的数据通过Data Frame发送给待添加设备B。
4、待添加设备B用自己的私钥解密所述加密后的数据获得主路由A的SSID和密码后,利用所述主路由A的SSID和密码去连接主路由A,从而加入所述手机C和主路由A所组成的WiFi网络中。
可选方案二:(采用Beacon Frame的方式)
1、待添加设备B恢复出厂上电后,每隔一段时间(可以采用默认值)通过信标帧(Beacon Frame)的方式,向外广播自己的WiFi信息时,将自己的公钥添加到Vendor Specific(厂商指定参数),一同广播出去。Beacon Frame的格式如下表3所示(IEEE std 802.11-2007 P80-81):
表3
Figure PCTCN2016113850-appb-000003
2、主路由A收到待添加设备B广播的B的公钥后,使用B的公钥对自己的SSID和密码进行加密(可选的,可以只对所述密码进行加密),并将加密后的数据通过Data Frame(数据帧)发送给待添加设备B。
3、待添加设备B用自己的私钥解密所述加密后的数据获得主路由A的SSID和密码后,利用所述主路由A的SSID和密码去连接主路由A,从而加入所述手机C和主路由A所组成的WiFi网络中。
本发明实施例提供的设备之间组网的方法,无需用户手机(即所述设备C)多次与路由器(即所述路由器A)建立WiFi连接,组网过程中,用户手机只需向连接的路由器发起组网请求(请求将设备B添加到所述用户手机和路由器建立的WiFi网络中),由路 由器主动向待添加设备B发送建立连接所需要的信息,从而将待添加设备B也连接到该路由器上,提高了组网的效率和可靠性。
本发明实施例提供的设备之间组网的方法不仅仅可以用在HiLink连接协议上,还可以用在所有基于802.11的组网环境中。
本发明实施例提供的设备(可以为所述路由器A或所述设备C)的结构示意图如图3所示,各模块可以通过总线相连。当所述设备为路由器时,所述触摸显示屏为可选的。当所述设备为设备C时,其具体可以为手机,其具体结构可以参考现有的手机的结构。如图3所示的设备可用于执行上述方法实施例提供的方法。所述收发器可以是具有wifi通信接口的wifi通信模块。
本发明各方法实施例之间相关部分可以相互参考;各装置实施例所提供的装置用于执行对应的方法实施例所提供的方法,故各装置实施例可以参考相关的方法实施例中的相关部分进行理解。
本发明各实施例中提供的消息/帧、模块或单元的名称仅为示例,可以使用其他名称,只要消息/帧、模块或单元的作用相同即可。
还需要说明的是,在本文中,诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来,而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分步骤是可以通过程序来指令相关硬件来完成,所述的程序可以存储于一投影设备的可读存储介质中,该程序在执行时,包括上述全部或部分步骤,所述的存储介质,如:FLASH、EEPROM等。
