现在的智能设备，以WiFi品类居多，比如智能插座、智能空调、智能空气净化器等。为保证这些智能设备的正常使用，首先需要将这些智能设备连接入网。由于家庭WiFi网络的普及,目前普遍采用WiFi网络与路由器(也可以称为接入点)完成连接,进而与手机/云端进行数据交互。
但是，由于这些智能设备没有人机交互界面，不具有像电脑、手机上可以展示的搜索、选择指定路由器以及输入连接密码的配置界面，从而不能自主地完成网络配置，因此，必须先解决智能设备正确连接路由器的问题。

本发明实施例提供了一种计算机存储介质，用于储存计算机程序，所述计算机程序使计算机执行时实现上述第四方面中的路由器的SSID获取方法。
第七方面，本发明实施例提供一种路由器的SSID获取***，包括：
配网设备、路由器和待入网设备；
所述路由器，用于发送信标帧，所述信标帧中包括所述路由器的SSID和BSSID；
所述配网设备，用于发送配网同步帧，所述配网同步帧中包括所述路由器的BSSID；
所述待入网设备，用于根据接收到的所述信标帧存储所述SSID和所述BSSID之间的对应关系，以及根据所述配网同步帧中的所述BSSID查询所述对应关系以获取所述SSID。
第八方面，本发明实施例提供一种服务集标识获取的方法，应用于待入网设备，包括：
接收入网设备发送的第一消息，所述第一消息包括第一信道信息以及第一服务集标识；
根据第一信道信息获取信标帧，所述信标帧包括第二服务集标识以及第二基础服务集标识；
根据所述第一服务集标识以及所述第二服务集标识确定目标服务集标识。
本发明实施例中，路由器对应的WiFi网络的网络名称可以用服务集标识(Service Set Identifier,简称SSID)来表示，路由器的地址信息可以用基础服务集标识(Basic Service Set Identifier,简称BSSID)来表示。在无线局域网中，BSSID即为无线路由器的介质访问控制(Media Access Control，简称MAC)地址，SSID即为无线网络的网络名称。本发明实施例中，路由器的SSID即是指路由器对应的WiFi网络的网络名称。
在本发明实施例中，诸如手机等配网设备可以与路由器预先建立连接，即配网设备已经联网，诸如智能家电等待入网设备还未联网，在配网设备对待入网设备进行网络配置的过程中，待入网设备需要获取该路由器的SSID亦即手机所接入的WiFi网络的网络名称，当然，待入网设备还需要获得网络的接入密码(PASSWD)等信息，只是PASSWD等信息可以采用传统方式获得。在本发明方案中，待入网设备也可以是待配网设备。待配网设备可以是智能家居设备(如常用的需要接入互联网的白电、小家电、照明等等)，接入点，各种传感器设备等。针对路由器的SSID的获取，一方面，路由器可以以一定时间间隔不断广播发出信标帧，信标帧中包括自己的SSID和BSSID，从而，接收到该信标帧的待入网设备解析该信标帧以存储SSID和BSSID之间的对应关系，另一方面，配网设备在对待入网设备进行网络配置时，可以广播发送配网同步帧，配网同步帧中包括配网设备所接入的路由器的BSSID。基于此，待入网设备收到配网同步帧后，根据其中包含的BSSID查询本地存储的各对应关系，若本地存储有与该BSSID对应的对应关系，则根据该对应关系直接获取该BSSID对应的SSID即可，从而，即使基于传统的网络配置方案进行SSID和PASSWD的多个字节的逐次发送过程中SSID对应的多个字节在传输过程中有丢失，基于本方案也能正确获得SSID，避免由于不能获取SSID而导致的配网失败问题， 从而提高了网络配置的成功率。

另外，下述各方法实施例中的步骤时序仅为一种举例，而非严格限定。
在介绍本发明实施例提供的网络配置方案之前，先对传统的采用SmartConfig模式进行网络配置的过程中容易导致的配网失败问题进行说明。
首先，在一种由配网设备、路由器、待入网设备构成的典型的配网***下，配网设备比如可以是手机、待入网设备比如可以是智能家电，配网设备已经与路由器建立连接，即配网设备已经接入WiFi网络，配网设备需要对作为信息孤岛的待入网设备进行网络配置，即将包含路由器的网络名称即SSID、接入密码即PASSWD以及一些辅助信息(比如SSID长度、PASSWD的长度、CRC、Flag等等)的配网信息传输给待入网设备，以使待入网设备基于这些配网信息接入路由器亦即接入WiFi网络。
目前，SmartConfig模式主要采用802.11和802.2的长度(Length)字段或目的MAC地址(Destination)字段来传输这些配网信息。以采用Length字段传输配网信息来说，受限于Length字段能够承载的比特位数(12个比特位)，配网设备在对配网信息进行编码后，由于编码后得到的比特位数远远高于Length字段能够承载的位数，因此，为完成配网信息的完整传输，配网设备需要发送若干个配网数据帧才行，每个配网数据帧中包含一个Length字段。实际上，Length字段的12个比特位往往不能完全被用于进行配网信息的传输，为描述方面，假设每次只能传输8个比特即一个字节。假设SSID和PASSWD的长度都为12个字节，辅助信息长度为6个字节，那么至少需要发送30个配网数据帧才能完整地发送完配网信息。
但是，如果这30个字节中的任何一个字节在传输过程中丢失都将使得待入网设备无 法正确解析出路由器的SSID和PASSWD，从而无法接入网络，配网失败。由于每一个字节丢失的概率大致相同，所以理论上相同的时间内，SSID和PASSWD的长度越长，出错的概率越高，正确解析路由器的SSID和PASSWD的概率同样越低。
基于此，如果SSID可以自动补齐，相当于不传输SSID，可以有效减少真实的传输长度，进而提高配网成功率。从而，本发明实施例提供了一种自动获取路由器的SSID的方案，配网过程中可以有效减少需传输字节数(如果SSID和PASSWD长度相同，不考虑辅助信息，相当于将传输的字节长度减少为原来长度的50％)，进而提高配网的效率和成功率。
下面结合如下的一些实施例对本发明实施例提供的自动获取路由器的SSID的方案进行介绍。
图1为本发明实施例提供的一种路由器的SSID获取***的组成示意图，如图1所示，该***可以包括：配网设备、路由器和待入网设备。
路由器，用于发送信标帧，信标帧中包括路由器的SSID和BSSID。
配网设备，用于发送配网同步帧，配网同步帧中包括路由器的BSSID。
待入网设备，用于根据接收到的信标帧存储SSID和BSSID之间的对应关系，以及根据配网同步帧中的BSSID查询该对应关系以获取SSID。
图1所示***中，配网设备可以是手机等用户终端，该配网设备可以通过与路由器建立连接而接入WiFi网络，或者，该配网设备也可以通过与其他入网设备连接而接入网络，但是该配网设备以某种方式获得了上述路由器的诸如SSID、BSSID等信息。待入网设备可以是诸如智能冰箱、智能音箱、机器人等终端。配网设备中安装有与待入网设备对应的App，在日常应用中，通过该App用户对该待入网设备进行控制，比如对机器人进行开关控制、行走路线控制等。
在用户通过配网设备对待入网设备进行网络配置的过程中，首先，用户通过操作配网设备将配网设备接入WiFi网络即与路由器建立连接，之后，通过操作待入网设备对应的App来触发对待入网设备的网络配置，比如点击App界面中的“网络配置”按钮以触发网络配置过程。
基于用户的触发，配网设备可以先广播发送一次或多次配网同步帧。由于在802.11的MAC层协议中规定了多种类型的数据帧，因此，本发明实施例中的配网同步帧可以选自802.11的MAC层协议中规定的多种类型的数据帧中的任一种，将选择出的数据帧中的Length字段或Destination字段填充用于标识该数据帧作为配网同步帧的字符串。也就 是说，将Length字段中填充为预设值亦即预设长度的数据帧作为配网同步帧。
可以理解的是，由于是从多种数据帧中选择一种作为配网同步帧的，配网同步帧中除了包含被填充有预设的字符串的Length字段外，还会包含数据帧中本来就包含的其他字段，比如源MAC地址字段、BSSID字段等等，因此，在配网同步帧中还会包括配网设备所接入的路由器的BSSID以及配网设备的MAC地址等明文信息。
当待入网设备接收到配网设备发送的配网同步帧后，根据Length字段中填充的预设字符串得知接收到的是配网同步帧，从而可以从中解析出路由器的BSSID、配网设备的MAC地址等信息。
其中，根据该配网设备的MAC地址，待入网设备可以锁定配网设备，即得知发送端是谁。
综上，基于接收到的配网同步帧，待入网设备可以锁定配网设备，并且知道该配网设备所接入的路由器的BSSID。
另一方面，配网设备所连接的路由器会按照一定的时间间隔(比如100毫秒)对外广播发送信标帧(beacon帧)，该beacon帧中包含路由器的BSSID和SSID。接收到该信标帧的待入网设备把接收到的路由器的SSID和BSSID对应存储下来。比如，待入网设备可以维护一个路由器列表，该列表中存储有待入网设备接收的各个beacon帧中所携带的一对SSID和BSSID。
基于此，对于待入网设备来说，如果其一旦根据配网同步帧得到了某路由器的BSSID，就可以根据该BSSID去查找当前的路由器列表，如果路由器列表中包含了该BSSID与某个SSID之间的对应关系，则可以直接基于该对应关系获取到该路由器的SSID。
为实现待入网设备的入网，待入网设备不仅要获得路由器的SSID，至少还需要获取PASSWD，PASSWD的获取过程可以采用传统的SmartConfig模式实现，从而与传统配网方式兼容。传统的SmartConfig模式，如前文所述，就是对配网信息进行编码，之后通过逐次发送配网数据帧进行编码后的配网信息的传输。详细的传输过程后续实施例中介绍。
综上，一方面，即使后续配网设备还是按照传统的方式发送包含SSID和PASSWD等的配网信息，该配网信息在传输过程中如果SSID对应的多个字节发生丢失等异常，也不会影响待入网设备对SSID的正确获取。
另一方面，由于通过这种方式可以获得SSID，则可选地，后续配网设备在发送配网信息时，可以不用再发送SSID。也就是说，配网过程中相当于只需要传输PASSWD字段和辅助信息就可以达到配网的目的。如果SSID和PASSWD的长度相等，辅助信息的长度 较短，理论上配网效率会提升将近一倍，配网成功率也会得到显著提高。
下面分别以配网设备、待入网设备的角度对本发明实施例提供的路由器的SSID获取方法进行详细介绍。
图2为本发明实施例提供的一种路由器的SSID获取方法的流程图，该路由器的SSID获取方法可以由图1所示的待入网设备来执行。如图2所示，该方法包括如下步骤：
201、接收路由器发送的信标帧，信标帧中包括路由器的SSID和BSSID。
202、存储SSID和BSSID之间的对应关系。
203、接收配网设备发送的配网同步帧，配网同步帧中包括路由器的BSSID。
204、根据配网同步帧中的BSSID查询所述对应关系以获取SSID。
如前文所述，配网同步帧中的长度字段(即Length字段)或目的MAC地址字段(即Destination字段)填充有预设的用于标识配网同步帧的字符串。从而，待入网设备解析出该预设字符串得知接收到的是配网同步帧，解析出其中包含的路由器的BSSID，基于该BSSID查询本地存储的对应关系，得到对应的SSID。
上述步骤的执行过程的详细描述可以参加前文实施例中的说明，在此不赘述。
另外，如前文所述，上述配网同步帧中还可以包括配网设备的MAC地址，从而，待入网设备可以根据配网设备的MAC地址锁定配网设备。锁定配网设备是指待入网设备记录下是哪个配网设备发送的配网同步帧，而配网设备可以用其MAC地址来唯一标识，从而，相当于是记录下配网设备的MAC地址与其发送的配网同步帧中的BSSID之间的对应关系。另外，通过锁定配网设备，待入网设备也知道后续需要接收谁发送的配网信息，即需要接收该配网设备发送的配网信息。
如前文所述，如果考虑与现有的SmartConfig模式兼容，后续配网设备发送的配网信息中可以包括路由器的SSID、PASSWD以及辅助信息。但是，如果不考虑兼容问题，后续配网设备发送的配网信息中可以仅包括PASSWD以及辅助信息，而不包括SSID。
简单来说，配网设备在发送配网信息时，可以从802.11的MAC层协议中所规定的多种数据帧中选择一种用于进行配网信息的发送，本发明实施例中，将选择出的用于进行配网信息发送的数据帧称为配网数据帧，在配网数据帧的Length字段或Destination字段来传输这些配网信息。
以使用Length字段来传输配网信息为例，受限于该Length字段能够承载的比特位数，每个配网数据帧中仅能够填充配网信息中的部分信息，可以理解的是，该部分信息是指对完整的配网信息进行编码后得到的完整比特字符串中的部分，从而，配网设备将 需要依次发送多个配网数据帧才能完成配网信息的发送。
基于此，待入网设备接收配网设备根据路由器对应的配网信息依次发送的各配网数据帧，通过解析每个配网数据帧中包括的配网信息中的部分信息，最终获得该路由器的配网信息，基于得到的配网信息连接入网。
可以理解的是，如果该配网信息中包含有路由器对应的SSID，而在发送该SSID的过程中，可能需要使用多个配网数据帧，如果其中的任一配网数据帧丢失，对于待入网设备来说并无影响，因为待入网设备已经基于配网设备发送的配网同步帧和路由器发送的信标帧得到了路由器对应的SSID。这也就意味着，即使配网数据帧中包括路由器的SSID，使得待入网设备可以从中解析出该SSID，待入网设备也会以根据BSSID查询得到的SSID替换掉从配网数据帧中解析得到的SSID。
图3为本发明实施例提供的另一种路由器的SSID获取方法的流程图，该路由器的SSID获取方法可以由图1所示的配网设备来执行。如图3所示，可以包括如下步骤：
301、与路由器建立通信连接。
302、发送配网同步帧，配网同步帧中包括路由器的BSSID，以使接收到配网同步帧的待入网设备在确定本地已存储有该BSSID后，根据本地存储的该BSSID和SSID的对应关系获取该SSID。
其中，配网同步帧中的长度字段或目的MAC地址字段填充有预设的用于标识配网同步帧的字符串，以供待入网设备据此识别该配网同步帧。
配网设备发送配网同步帧的过程可以参加前文实施例中的说明，在此不赘述。
另外，配网设备在发送完配网同步帧后，根据路由器对应的配网信息依次发送各配网数据帧，每个配网数据帧中包括配网信息中的部分信息，以使待入网设备解析各配网数据帧以获得配网信息，其中，每个配网数据帧中包含的部分信息承载于配网数据帧的长度字段即Length字段或目的MAC地址字段即Destination字段。
其中，在进行配网数据帧的发送过程中，可选地，配网设备可以按照如下方式进行发送：
根据预设编码格式，对配网信息进行编码；
对编码后的配网信息进行分组划分；
依次发送每个分组对应的分组帧和多个配网数据帧，分组帧中包括对应分组的分组标识，多个配网数据帧与对应分组内包括的多个字符串一一对应，该多个字符串是编码后的配网信息中的至少一部分信息；
其中，前述配网同步帧作为第一个分组的分组帧。
其中，分组标识承载于分组帧的Length字段或Destination字段中。
其中，每个配网数据帧中的Length字段或Destination字段中包括对应字符串和所述对应字符串的组内偏移量。也就是说，以Length字段为例，Length字段占12比特位，可以将这12比特位划分为两个部分，其中的第一部分为用于填充组内偏移量，第二部分用于填充配网信息中的部分信息即对应于该部分信息的一定长度的字符串。实际应用中，可以根据实际需求灵活划分这两个部分各自占用的位数。
从而，编码配网信息后得到完整的配网信息对应的比特位序列，上述对编码后的配网信息进行分组的过程就是：根据上述第二部分所占用的比特位数对该编码后得到的比特位序列进行划分，得到若干字符串，每个字符串需要用一个配网数据帧来传输；另外，为了保证待入网设备能够知道各配网数据帧的发送顺序，需要对每个配网数据帧进行序号标记，而本实施例中，通过分组标识和组内偏移量来进行配网数据帧的序号标记亦即是对配网数据帧中包含的字符串进行序号标记。
其中，本实施例中提到的分组帧，也可以从802.11的MAC层协议所规定的多种数据帧中选择一种用作分组帧，以Length字段为例，不同分组帧的Length字段中填充的分组标识不同，其中，第一个分组帧中填充的是第一个分组的分组标识，第二个分组帧中填充的是第二个分组的分组标识，依次类推。值得说明的是，第一个分组帧其实就可以是前述配送同步帧。
下面以如下示例来示意配网设备的配网信息的发送过程，该示例以用Length字段来进行配网信息的传输为例，并且假设每个配网数据帧的Length字段中第二部分可以填充的字符串位数为8位即一个字节。
假设完整的配网信息经过编码后包括以下字节：
12 0F 0C 00 34 4D 41 4C 4C 00 32 4F 55 54 45 52 0D 08
假设每8个字节分成一组，那么总共分成如下三组：
第1组：12 0F 0C 00 34 4D 41 4C
第2组：00 32 4F 55 54 45 52 0D
第3组：08
组内偏移量分别表示为：0x100,0x180,0x200,0x280,0x300,0x380,0x400,0x480，其中：
0x100：表示组内第1个字节
0x180：表示组内第2个字节
……
以此类推。
另外，假设依次发送的分组帧的Length字段中各自填充的分组标识为：0x3E0，0x3E1，0x3E2，…….，0x3EF，其中：
0x3E0：表示第1个分组
0x3E1：表示第2个分组
……
以此类推。
基于上述假设情况，配网设备的发送过程为：
第1个帧：配网同步帧亦即第1个分组帧，Length字段中填充为0x3E0；
第2个帧：第1个分组内的第1个配网数据帧，Length字段中填充为0x100+0x12＝0x112；其中，Length字段被划分为+号之前的第一部分和之后第二部分；
第3个帧：第1个分组内的第2个配网数据帧，Length字段中填充为0x180+0x0F＝0x18F；
第4个帧：第1个分组内的第3个配网数据帧，Length字段中填充为0x200+0x0C＝0x20C；
第5个帧：第1个分组内的第4个配网数据帧，Length字段中填充为0x280+0x00＝0x280；
第6个帧：第1个分组内的第5个配网数据帧，Length字段中填充为0x300+0x34＝0x334；
第7个帧：第1个分组内的第6个配网数据帧，Length字段中填充为0x380+0x4D＝0x3CD；
第8个帧：第1个分组内的第7个配网数据帧，Length字段中填充为0x400+0x41＝0x441；
第9个帧：第1个分组内的第8个配网数据帧，Length字段中填充为0x480+0x4C＝0x4CC；
第10个帧：第2个分组帧，Length字段中填充为0x3E1；
第11个帧：第2个分组内的第1个配网数据帧，Length字段中填充为0x100+0x00＝0x100；
第12个帧：第2个分组内的第2个配网数据帧，Length字段中填充为0x180+0x32＝0x1B2；
第13个帧：第2个分组内的第3个配网数据帧，Length字段中填充为0x200+0x4F＝0x24F；
第14个帧：第2个分组内的第4个配网数据帧，Length字段中填充为0x280+0x55＝0x2D5；
第15个帧：第2个分组内的第5个配网数据帧，Length字段中填充为0x300+0x54＝0x354；
第16个帧：第2个分组内的第6个配网数据帧，Length字段中填充为0x380+0x45＝0x3C5；
第17个帧：第2个分组内的第7个配网数据帧，Length字段中填充为0x400+0x52＝0x452；
第18个帧：第2个分组内的第8个配网数据帧，Length字段中填充为0x480+0x0D＝0x48D；
第19个帧：第3个分组帧，Length字段中填充为0x3E2；
第20个帧：第3个分组内的第1个配网数据帧，Length字段中填充为0x100+0x08＝0x108。
可选地，所有的字节发送完后，可以再从头重复发送，以保证正确接收。
基于该发送过程，待入网设备每接收到一帧后，按照相应的编码规则解析出相应的字符串，并回复字符串的位置顺序即可。

具体的，第一服务集标识为从DPP配置应答消息中获取的SSID。第二服务集标识为从信标帧中获取的SSID。如果待配网设备判断第一SSID和第二SSID的编码格式是否相同，如果相同，则待配网设备会在关联接入点的过程中发送相同的SSID。如果待配网设备判断第一SSID和第二SSID的编码格式不同，则待配网设备会在关联接入点的过程中发送第二SSID。可选的，待配网设备可以找到DPP配置应答消息中和在信标帧中相同的BSSID，并且通过BSSID来找到对应的第一SSID以及第二SSID。
