背景技术
随着互联网技术的发展，越来越多的家庭使用上了家庭网络。通常，家庭用户是通过购买运营商提供的宽带上网业务来实现家庭网络的组建。一般情况下，运营商往往只给用户提供网络接入设备(例如家庭网关等)，以供用户接入到网络中。在一些场景中，为了能够使更多的设备接入到网络中，用户通常会选择自行购买接入点(access point，AP)设备(例如路由器等)来实现家庭组网。
在用户自购AP设备进行家庭组网的场景下，当用户由于家庭网络出现问题而向运营商报障时，负责维护网络的人员需要直观地知道用户家里是否有自购的AP设备，以判断网络故障问题是否是由用户自购的AP设备引入的。
目前，判断用户家里是否有自购的AP设备通常是识别用户家中接入网络的设备具体的信息(例如厂商、型号等)，然后基于设备的厂商、型号等信息进一步判断该设备是否是AP设备。这种方案往往需要先建立识别库，识别库中包括有市面上各种AP设备对应的厂商以及型号等信息。然而，对于AP设备而言，能够生产AP设备的厂商众多，且每个厂商在不同的时期还会推出大量新的不同型号的AP设备，识别库的维护成本较高。因此，需要一种低成本的识别方案，用于识别接入网络中的设备是否为AP设备。

如图1所示，图1为本申请实施例中提供的系统架构的示例图。其中，服务器通过网络与内置于网络接入设备中的Agent服务通信连接，服务器与Agent服务之间可以互相收发信息；网络接入设备通过其自身的网络接口接入有多个接入设备，即多个接入设备通过接入到网络接入设备来实现接入网络；其中，接入设备1同时为一个AP设备，能够通过开启无线热点的方式来为其他的设备提供无线接入服务，AP设备可以下挂有一个或多个接入设备，这些下挂于AP设备的接入设备能够通过AP设备实现网络的接入；此外，网络接入设备可以通过搜索无线热点的方式来获取到AP设备对应的无线热点信息。
本申请实施例中所指的网络接入设备具体可以是网关、路由器、交换机、DSL或PON等能够提供网络接入服务的设备，具体此处不做限定。在本实施例以及后续实施例中，仅以网络接入设备为例进行介绍。
此外，接入设备可以是个人电脑、笔记本电脑、手机、智能音箱或路由器等具有接入网络功能的设备，具体此处不做限定。在本实施例以及后续实施例中，仅以接入设备为例进行介绍。
值得注意的是，在本申请实施例中，对设备进行识别的过程可以在网络接入设备侧进行，也可以在服务器侧进行，为了便于理解，下面将分别从网络接入设备和服务器这两个角度对本申请实施例提供的设备识别的方法进行详细的介绍。
首先，以下将从网络接入设备的角度对本申请实施例提供的设备识别的方法进行介绍，如图2所示，图2为本申请实施例提供的一种设备识别的方法的流程示例图。
本申请实施例提供的一种设备识别的方法，包括：
201、网络接入设备获取接入设备的MAC地址；
本实施例中，当需要确定接入到网络接入设备的接入设备中是否存在有AP设备时，可以由网络接入设备获取接入设备的MAC地址。可以理解的是，在网络中，由于每个连接网络的设备都需要分配唯一的IP地址，因此为了能够给每一个接入到网络中的设备分配唯一的IP地址，接入设备通常是通过DHCP协议接入到网络接入设备中的。其中，DHCP在给接入设备分配IP地址时，通常需要获取接入设备的相关信息，例如接入设备的MAC地址和接入设备的名称等信息，然后给接入设备分配一个唯一的IP地址，并且将接入设备的相关信息和分配给接入设备的IP地址关联起来，以确保每个接入设备能够分配到一个唯一的IP地址。通常，接入设备的相关信息和分配给接入设备的IP地址会作为DHCP信息记录在网络接入设备中，因此，网络接入设备在需要获取接入设备的MAC地址时，通过获取接入设备对应的DHCP信息即可实现接入设备MAC地址的获取，具体地，网络接入设备可以通过采集其下挂设备列表中对应的DHCP信息的方式，来获取接入设备的MAC地址。
在实际应用中，网络接入设备中内置有Agent服务，Agent服务可以通过向网络接入设备发送命令来获取接入设备的MAC地址。具体地，首先由网络接入设备内置的Agent服务生成一个GET_SUB_DEVICE_LIST命令(即设备信息获取命令)，然后Agent服务向网络接入设备发送该GET_SUB_DEVICE_LIST命令，网络接入设备根据该GET_SUB_DEVICE_LIST命令采集其下挂设备列表中对应的DHCP信息，其中，网络接入设备的下挂设备列表中包括有通过局域网接口(LAN接口)接入到网络接入设备的设备以及通过网络接入设备所开启的WIFI热点接入到网络接入设备的设备，换句话说，网络接入设备的下挂设备列表中包括有通过有线的方式接入的设备以及通过无线的方式接入的设备。
其中，GET_SUB_DEVICE_LIST命令一般可以为JSON格式的命令，主要用于请求获取下 挂设备的信息，具体地，GET_SUB_DEVICE_LIST命令可以如下所示：
Figure PCTCN2020103624-appb-000001
显然，通过以上的示例可以看出，GET_SUB_DEVICE_LIST命令通过向网络接入设备请求获取参数值的方式来指示网络接入设备获取下挂设备对应的DHCP信息。
具体地，网络接入设备在获取到下挂设备对应的DHCP信息之后，可以向Agent服务返回响应信息，该响应信息与GET_SUB_DEVICE_LIST命令相对应，具体可以如下所示：
Figure PCTCN2020103624-appb-000002
在Agent服务获取到网络接入设备返回的DHCP信息之后，Agent服务便可以在DHCP信息中获取到下挂设备列表中每个接入设备对应的MAC地址。
值得注意的是，为了能够实现Agent服务主动向网络接入设备发送命令并且获取相应的MAC地址，可以预先给Agent服务提供可调用的API和动态链接库(dynamic link library，DLL)文件，其中，DLL文件可以向Agent服务提供代码、数据或函数，使Agent服务可以调用不属于其可执行代码的函数，具体地，在本实施例中，Agent服务可以根据DLL文件中的指令调用预提供的API，从而实现向网络接入设备发送命令并且获取相应的MAC地址。
在本实施例中，上述的API和DLL文件可以是由与网络接入设备连接的服务器提供给Agent服务的，也可以是由运维人员通过预先安装在网络接入设备中来提供给Agent服务的，此处不做具体限定。通常来说，在需要通过Agent服务获取网络接入设备下挂设备列表信息且网络接入设备中没有安装有相应的API和DLL文件的情况下，可以由服务器向Agent服务提供API和DLL文件，从而保证能够可靠地获取下挂设备列表信息。
202、网络接入设备获取WIFI热点的MAC地址；
在本实施例中，同样可以通过内置于网络接入设备中的Agent服务向网络接入设备发送命令来获取WIFI热点的MAC地址。其中，该WIFI热点指的是位于网络接入设备周边(即目标区域)的WIFI热点，Agent服务可以先生成一个GET_NEIGH_BOUR命令(即热点信息获取命令)，然后向网络接入设备发送该GET_NEIGH_BOUR命令，以使得网络接入设备可以根据该GET_NEIGH_BOUR命令启动WIFI芯片，来采集周边的WIFI热点信息；最后由网络接入设备向Agent服务返回采集到的WIFI热点信息，其中，WIFI热点信息中通常包括有WIFI热点的MAC地址以及WIFI热点的名称等信息，Agent服务基于该WIFI热点信息即可以获取到网络接入设备周边区域的WIFI热点的MAC地址。
可以理解的是，由于用户家庭网络中所采用的AP设备通常为功率较小的设备，这些 AP设备所发射的WIFI信号的有效传输距离通常为数十米左右(10米至30米)，一般来说，用户家庭网络中自购的AP设备可以有效地覆盖用户家中的各个角落。此外，用户在组建家庭网络的过程中，运营商所提供的网络接入设备通常也是布置于用户家中的。因此，在本实施例中，通过布置于用户家中的网络接入设备能够有效地采集到覆盖在用户家中的WIFI热点信息。
具体地，GET_NEIGH_BOUR命令一般可以为JSON格式的命令，主要用于请求网络接入设备获取其周边区域的WIFI热点信息，GET_NEIGH_BOUR命令的具体信息结构与上述的GET_SUB_DEVICE_LIST命令类似，具体可以参阅上面的描述，此处不再赘述。
值得注意的是，本实施例中，步骤201与步骤202之间没有必然的先后顺序，可以先执行步骤201，也可以先执行步骤202，也可以同时执行步骤201和202，具体此处不做限定。
203、若接入设备的MAC地址和WIFI热点的MAC地址属于同一个地址段，网络接入设备确定接入设备为AP设备；
在本实施例中，在Agent服务获取到接入设备的MAC地址和WIFI热点的MAC地址之后，Agent服务可以对接入设备的MAC地址和WIFI热点的MAC地址进行比较，来判断接入设备的MAC地址和WIFI热点的MAC地址是否属于同一个地址段。
其中，判断接入设备的MAC地址和WIFI热点的MAC地址是否属于同一个地址段指的是判断接入设备的MAC地址和WIFI热点的MAC地址是否是相邻的地址，或者是判断这两个地址是否均位于一个连续的地址段内，如果两个地址是相邻的地址或者均位于一个连续的地址段内，则可以确定该接入设备为AP设备。
可以理解的是，由上述的介绍可知，MAC地址中的前6位16进制数代表网络硬件制造商的编号，是由IEEE所分配的一个固定的编号；而MAC地址的后6位16进制数则代表该制造商所制造的某个网络产品的系列号，该系列号可以认为是该网络产品的唯一“身份标识”。也就是说，MAC地址的后6位16进制数是由制造商自定义的，而在一般情况下，制造商为了便于网络产品的管理，其对于网络产品的MAC地址的编号是有一定的规律的。
对于一个AP设备，制造商会分配一个连续的地址段给AP设备以用于不同的MAC地址，例如WIFI热点MAC地址、上行连接MAC地址、LAN口MAC地址等等，这些MAC地址都是连续的。具体地，以AP设备为路由器为例，假设该路由器有1个WAN口(广域网接口，用于连接网络接入设备的接口)，4个LAN口(局域网接口，用于接入其他的网络设备，例如个人电脑或笔记本电脑等)以及1个WIFI热点频段(例如运行于2.4GHz或5GHz频段的WIFI热点)。那么，该路由器至少有6个连续的MAC地址，其中，路由器的1个WAN口对应一个上行连接MAC地址，该上行连接MAC地址即为网络接入设备通过获取下挂设备列表的DHCP信息能够获取到的MAC地址，路由器的4个LAN口对应4个LAN口MAC地址，路由器的1个WIFI热点频段对应1个热点MAC地址，这6个MAC地址是连续的。例如，上述的6个MAC地址具体可以如下所示：
上行连接MAC地址：08：00：20：0A：8C：00；
4个LAN口MAC地址：08：00：20：0A：8C：01，08：00：20：0A：8C：02，08：00：20：0A：8C：03，08：00：20：0A：8C：04；
热点MAC地址：08：00：20：0A：8C：05。
由以上示例可以看出，上述的6个MAC地址的前十位十六进制数值均相同，后两位十 六进制数值分别为00至05，也就是说，这6个MAC地址是连续的。
基于上述的分析可以得知，对于用户家庭中的一个AP设备来说，该AP设备在接入到网络接入设备时所使用的MAC地址是一个上行连接MAC地址，而该AP设备在提供无线接入服务时(即开启WIFI热点时)所使用的MAC地址则是另一个MAC地址(即热点MAC地址)，而这两个MAC地址又是属于同一个地址段内的。因此，在本实施例中，可以将网络接入设备获取到的接入设备的MAC地址与WIFI热点的MAC进行对比，如果这两个MAC地址属于同一个地址段，则可以认为这两个MAC地址是同一个设备的地址，即确定该接入设备是一个具有开启WIFI热点以提供无线接入服务功能的AP设备。
具体地，考虑到不同的制造商在给AP设备分配MAC地址时可能会采用不同的习惯，并且对于不同的AP设备来说，不同的AP设备所具有的MAC地址段的长度也是不同的，因此，在本实施例中，判断接入设备的MAC地址和WIFI热点的MAC地址是否属于同一个地址段，可以采用以下的两种方式：
1、若接入设备的MAC地址与WIFI热点的MAC地址之间的差值绝对值小于或等于预设阈值，则确定接入设备的MAC地址和WIFI热点的MAC地址属于同一个地址段。
由于MAC地址通常表示为12个16进制数，因此，MAC地址实际上可以看做为一个由12个16进制数构成的数值，因此，在获得接入设备的MAC地址和WIFI热点的MAC地址之后，可以分别将这两个MAC地址转换为具体的数值，并且求取这两个数值之间的差值绝对值，如果差值绝对值小于或等于预设阈值(例如256)，则可以认为两个MAC地址是属于同一个地址段的。其中，预设阈值是根据大部分制造商给AP设备分配地址段的习惯来设置的，一般来说，制造商给AP设备所分配的地址段的长度不会大于256，即同一个AP设备中差值最大的两个MAC之间的差值也不会大于256，因此，在本实施例中可以设置预设阈值为256。可以理解的是，在实际应用中，该预设阈值是可以根据实际情况进行调整的，预设阈值越大，则最终识别为AP设备的接入设备则会越多，错误识别为AP设备的接入设备也会增加，识别错误率会提高，但是不容易漏识别AP设备(即一些AP设备没有被识别出来)；预设阈值越小，则识别精度会越高，相应的，也更容易漏识别。因此，在实际应用中，可以根据具体的识别需要，相应地调整预设阈值。
例如，假设接入设备的MAC地址为07：16：76：00：02：FF，WIFI热点的MAC地址为07：16：76：00：03：00，显然，这两个MAC地址的前8位16进制数均是相同的，即两个MAC地址之间的差值绝对值是由后4位16进制数决定的，其中，02：FF对应的数值具体为767(0*163+2*162+16*161+16*160)，03：00对应的数值具体为768(0*163+3*162+0*161+0*160)，因此，这两个MAC地址之间的差值绝对值为1，显然，接入设备的MAC地址和WIFI热点的MAC地址属于同一个地址段。
在实际应用中，可以分别将接入设备的MAC地址以及WIFI热点的MAC地址转换为一个由12个16进制数构成的数值之后，再对两个转换后的16进制数值作差，求取两个MAC地址的差值绝对值；另外，也可以是分别将接入设备的MAC地址以及WIFI热点的MAC地址转换为一个由10进制数构成的数值之后，再对两个转换后的10进制数值作差，求取两个MAC地址的差值绝对值，在此不对具体求取差值绝对值的过程进行限定。
此外，在确定接入设备的MAC地址与WIFI热点的MAC地址之间的差值绝对值的过程中，可以从两个MAC地址的低位数值开始计算相应的差值绝对值，在两个MAC地址的低位数值之间的差值绝对值满足小于或等于预设阈值的条件之后，再继续计算两个MAC地址的 高位数值之间的差值绝对值。例如，假设预设阈值为10，接入设备的MAC地址为07：16：76：00：02：20，WIFI热点的MAC地址为07：16：76：00：02：30，在确定两个MAC地址之间的差值绝对值的过程中，可以先比较两个MAC地址的后两位数值之间的差值绝对值，其中，接入设备的MAC地址后两位数值为20(转换为十进制后即为32)，WIFI热点的MAC地址后两位数值为30(转换为十进制后即为48)，显然，接入设备的MAC地址与WIFI热点的MAC地址的后两位数值之间的差值绝对值为16(48：32)，大于数值为10的预设阈值，因此，此时可以确定接入设备的MAC地址与WIFI热点的MAC地址不属于同一个地址段，而不需要继续比对两个MAC地址中其他位数值之间的差值，也不需要将整个MAC地址转换为一个具体的数值(例如16进制数值或者10进制数值)之后再作差，降低了计算量。
2、若接入设备的MAC地址的第一位数值至第N位数值与WIFI热点的MAC地址的第一位数值至第N位数值均相同，则确定接入设备的MAC地址和WIFI热点的MAC地址属于同一个地址段，其中，N为大于1的整数。
可以理解的是，对于一些制造商来说，为了便于对AP设备进行生产管理，其在给AP设备分配MAC地址的时候，分配给AP设备的多个MAC地址的前几位数值通常都是相同的。例如，以上述的路由器对应的6个MAC地址为例，6个MAC地址分别为：
08：00：20：0A：8C：00，
08：00：20：0A：8C：01，
08：00：20：0A：8C：02，
08：00：20：0A：8C：03，

显然，这6个MAC地址的前十位数值均是相同的，只有后两位数值是不相同的。基于此，在本实施例中，可以通过比较接入设备的MAC地址和WIFI热点的MAC地址这两个MAC地址的前N位数值是否相同，来判断两个MAC地址是否属于同一个地址段。其中，N为大于1的整数，具体可以为9、10或11等数值，在实际应用中，可以根据具体需要来设置N的数值。可以理解的是，N的数值越大时，接入设备被识别为AP设备所需要满足的条件也越高，例如，N为11时，接入设备的MAC地址只有在其前11位数值与WIFI热点的MAC地址的前11位数值相同时，才会被识别为AP设备，换句话说，N的数值越大时，识别的精度会越高，但是漏识别的概率也会越大；而N的数值越小时，识别的精度越低，但是漏识别的概率也会越小。因此，在实际应用中，可以根据实际的识别需要适应性地调整N的数值，从而在识别精度和漏识别概率中取得一个较好的平衡。
另外，在本实施例中，在判断得接入设备的MAC地址和WIFI热点的MAC地址属于同一个地址段之后，除了可以确定该接入设备为AP设备之外，还可以确定该接入设备与开启WIFI热点的设备为同一个设备，也就是说，可以将接入设备的信息和WIFI热点的信息关联起来，将该接入设备视为开启该WIFI热点的设备。这样一来，在一些场景下(例如需要确定开启WIFI热点的设备是哪一个设备的场景下)，可以快速地提供开启WIFI热点的设备信息，为如何确定开启WIFI热点的设备提供了可行的方案，增强了方案的灵活性。
204、网络接入设备接收服务器发送的设备识别请求；
在本实施例中，在负责家庭网络管理的运维人员需要获取用户家庭中是否存在有自购的AP设备时，运维人员可以通过在服务器的家庭网络管理系统上下发设备识别请求指令， 以使得服务器向用户家庭中的网络接入设备发送设备识别请求，其中，家庭网络管理系统是部署于服务器上的一种软件系统，能够与用户家庭中的网络接入设备通信连接，主要用于实现对用户家庭网络的管理。其中，家庭网络管理系统可以通过MQTT通道向网络接入设备发送设备识别请求。具体地，家庭网络管理系统可以是定期通过服务器向网络接入设备发送设备识别请求(例如由运维人员预先设置好家庭网络管理系统定期触发发送设备识别请求的指令)，也可以是在运维人员需要查询用户的家庭网络中是否存在有AP设备时再通过服务器向网络接入设备发送设备识别请求，在此不做具体限定。
205、网络接入设备向服务器发送被识别为AP设备的接入设备的信息。
在本实施例中，网络接入设备获取接入设备的MAC地址、获取WIFI热点的MAC地址以及根据接入设备的MAC地址和WIFI热点的MAC地址确定接入设备是否为AP设备等步骤均可以在网络接入设备启动之后便执行，或者是网络接入设备在工作过程中间隔一定的周期便执行上述的步骤，在网络接入设备确定得到具体某个或某几个接入设备为AP设备之后，网络接入设备可以将这些被识别为AP设备的接入设备对应的信息保存在本地的存储空间中。在网络接入设备获取到服务器发送的设备识别请求之后，便可以将预先保存在本地存储空间中的被识别为AP设备的接入设备对应的信息发送给服务器。其中，被识别为AP设备的接入设备的信息具体可以包括接入设备的MAC地址或接入设备的设备名称中的一种或多种。可以理解的是，接入设备的信息可以在获取DHCP信息的时候获取到，由于DHCP信息中通常会包括有接入设备的名称、接入设备的MAC地址等信息，因此，在确定了某个接入设备为AP设备之后，便可以将该接入设备对应的DHCP保存在本地的存储空间中，以作为该接入设备的待上报信息，直到网络接入设备获取到服务器下发的设备识别请求时，将该接入设备对应的待上报信息发送给服务器。显然，通过由网络接入设备主动执行识别接入设备的步骤并且保存被识别为AP设备的接入设备的信息，能够使得网络接入设备获取到设备识别请求时，快速向服务器反馈相应的信息，确保了AP设备信息的获取速度，有利于运维人员快速排障。
此外，在本实施例中，除了在接收到服务器发送的设备识别请求之后再由网络接入设备向服务器发送相应的接入设备信息，还可以是由网络接入设备间隔一定的周期主动向服务器发送被识别为AP设备的接入设备的信息，即网络接入设备定期主动向服务器反馈被识别为AP设备的接入设备的信息。例如，网络接入设备定期识别当前已接入的接入设备中是否存在有AP设备，并且在获得识别结果之后，主动向服务器发送被识别为AP设备的接入设备的信息。值得注意的是，网络接入设备可以在每一次进行AP设备的识别之后均向服务器反馈当前的识别结果，无论识别结果是识别到存在有AP设备还是未识别到存在有AP设备；此外，由于服务器在接收到网络接入设备发送的被识别为AP设备的接入设备对应的信息之后，通常都会将这些接入设备的信息保存在数据库中，因此，网络接入设备也可以是在识别到有新的AP设备之后，再给服务器反馈新识别到的AP设备对应的信息，而不需要每次在进行AP设备的识别之后都向服务器反馈相应的识别结果。可以理解的是，在网络接入设备主动向服务器发送接入设备的信息的情况下，在服务器接收到网络接入设备所发送的被识别为AP设备的接入设备的信息之后，服务器可以将这些接入设备的信息保存在数据库中，以便于在需要时能够及时显示该信息，例如在运维人员需要获知某一个家庭用户的家庭网络中是否存在有AP设备时，可以通过在服务器的家庭网络管理系统上通过查询数据库中来获取该信息。
本申请实施例中，通过获取接入设备对应的MAC地址，以及用户家中WIFI热点的MAC地址，然后比较接入设备的MAC地址和WIFI热点的MAC是否属于同一个连续的地址段，从而判断接入设备和开启WIFI热点的设备是否为同一个设备，进而识别接入设备是否为AP设备。由于识别过程中只需要获取接入设备的MAC地址以及WIFI热点的MAC，不再需要维护识别库，因此，可以降低识别的成本。
为了便于理解，以下将结合具体的例子对本申请实施例提供的设备识别的方法进行详细的介绍。
首先，由部署于服务器上的家庭网络管理系统向内置于网络接入设备中的Agent服务提供可调用的API和DLL文件；在网络接入设备启动之后，可以获取到家庭网络管理系统提供的API和DLL文件，网络接入设备可以启动其内置的Agent服务，并且由Agent服务加载API和DLL文件；在接入设备通过DHCP协议接入到网络接入设备时，网络接入设备可以记录接入设备对应的DHCP信息，具体包括接入设备的MAC地址和接入设备的设备名称等信息；其次，在Agent服务加载好API和DLL文件之后，Agent服务根据DLL文件中的指令调用预提供的API，来向网络接入设备发送GET_SUB_DEVICE_LIST命令；网络接入设备根据该GET_SUB_DEVICE_LIST命令采集连接到网络接入设备下的接入设备对应的DHCP信息，然后在采集完DHCP信息之后，向Agent服务返回采集到的DHCP信息，具体包括接入设备的MAC地址和接入设备的设备名称等信息；此外，Agent服务还根据DLL文件中的指令调用预提供的API，来向网络接入设备发送GET_NEIGH_BOUR命令；网络接入设备根据该GET_NEIGH_BOUR命令，启动WIFI芯片来采集周边的WIFI热点信息，并且在采集完毕之后向Agent服务返回相应的WIFI热点信息，具体包括WIFI热点的MAC地址和WIFI热点的名称等信息；最后，由Agent服务判断接入设备的MAC地址和WIFI热点的MAC地址是否属于同一个地址段内，如果是，则确定该接入设备为AP设备，并且向服务器发送该接入设备的信息。
请参阅图3，图3为本申请实施例提供的一种设备识别的方法的另一流程示例图。
本申请实施例提供的一种设备识别的方法，包括：
301、网络接入设备接收服务器发送的设备识别请求；
在本实施例中，当服务器侧的运维人员需要确定接入到网络接入设备的接入设备中是否存在有AP设备时，运维人员可以通过在服务器的家庭网络管理系统上下发设备识别请求指令，以使得服务器向用户家庭中的网络接入设备发送设备识别请求。
另外，若Agent服务中没有相应的API和DLL文件，那么服务器可以在向网络接入设备发送设备识别请求之前或者之后，向Agent服务提供API和DLL文件，其中，API和DLL文件的作用可以参考上述的步骤201和步骤202，在此不再赘述。
可以理解的是，本申请实施例中的设备识别请求具体可以是一个请求信息，也可以是两个请求信息，在设备识别请求为一个请求信息时，该请求信息用于同时请求获取接入设备的MAC地址和WIFI热点的MAC地址；在设备识别请求为两个请求信息时，这两个请求信息分别用于请求获取接入设备的MAC地址以及WIFI热点的MAC地址，另外，这两个请求信息可以是同时发送，也可以是具有任意的先后顺序，在此并不对两个请求信息的发送顺序做任何限定。
302、网络接入设备根据设备识别请求，获取接入设备的MAC地址；
在本实施例中，网络接入设备中内置的Agent服务在接收到服务器发送的设备识别请 求之后，再根据该设备识别请求来获取接入设备的MAC地址，也就是说，在本实施例中，Agent服务是在接收到设备识别请求之后，再获取接入设备的MAC地址。具体地，Agent服务获取接入设备的MAC地址的步骤与上述的步骤201相似，具体可以参阅上述的步骤201，在此不再赘述。
303、网络接入设备根据设备识别请求，获取WIFI热点的MAC地址；
在本实施例中，网络接入设备中内置的Agent服务在接收到服务器发送的设备识别请求之后，再根据该设备识别请求来获取WIFI热点的MAC地址，同样地，在本实施例中，Agent服务也是在接收到设备识别请求之后，再获取WIFI热点的MAC地址。具体地，Agent服务获取WIFI热点的MAC地址的步骤与上述的步骤202相似，具体可以参阅上述的步骤202，在此不再赘述。
值得注意的是，本实施例中，步骤302与步骤303之间没有必然的先后顺序，可以先执行步骤302，也可以先执行步骤303，也可以同时执行步骤302和303，具体此处不做限定。
304、若接入设备的MAC地址和WIFI热点的MAC地址属于同一个地址段，网络接入设备确定接入设备为AP设备；
本实施例中，步骤304与上述的步骤203相似，具体可以参阅上述的步骤203，在此不再赘述。
305、网络接入设备向服务器发送被识别为AP设备的接入设备的信息。
本实施例中，步骤305与上述的步骤205相似，具体可以参阅上述的步骤205，在此不再赘述。
在本实施例中，步骤301至步骤305与上述的步骤201至步骤205主要的区别在于：在步骤301至步骤305中，网络接入设备是在接收到服务器发送的设备识别请求后，再根据设备识别请求获取接入设备的MAC地址和WIFI热点的MAC地址，并且根据这两个MAC地址确定接入设备是否为AP设备，最后将被确定为AP设备的接入设备的信息发送给服务器；而在步骤201至步骤205中，网络接入设备是主动获取接入设备的MAC地址和WIFI热点的MAC地址，并且根据这两个MAC地址确定接入设备是否为AP设备，然后网络接入设备主动将被确定为AP设备的接入设备的信息发送给服务器，或者是先将被确定为AP设备的接入设备的信息存储在本地并且在获取到服务器发送的设备识别请求之后再将接入设备的信息发送给服务器。换句话说，在步骤301至步骤305中，网络接入设备是在接收到服务器发送的设备识别请求后，再进行AP设备的识别；而在步骤201至步骤205中，网络接入设备是主动进行AP设备的识别，然后主动向服务器反馈识别结果，或者是在接收到服务器发送的设备识别请求后，再发送预先获得的识别结果。
显然，在本实施例中，网络接入设备在接收到服务器发送的设备识别请求后再进行设备识别，能够确保识别结果是基于当前接入到网络接入设备中的接入设备以及当前网络接入设备周边的WIFI热点得到的，保证了识别结果的时效性，同时也避免了网络接入设备频繁向服务器发送识别结果，节省了信令消耗。
以上为从网络接入设备的角度对本申请实施例提供的设备识别的方法所进行的描述，以下将从服务器的角度对本申请实施例提供的设备识别的方法进行详细的介绍。如图4所示，图4为本申请实施例提供的一种设备识别的方法的流程示例图。
本申请实施例提供的一种设备识别的方法，包括：
401、服务器向网络接入设备发送地址获取请求；

402、网络接入设备根据地址获取请求获取接入设备的MAC地址；
本实施例中，网络接入设备获取接入设备的MAC地址的过程与上述的步骤201相似，具体可以参阅上述的步骤201，在此不再赘述。
403、网络接入设备根据地址获取请求获取WIFI热点的MAC地址；
本实施例中，网络接入设备获取WIFI热点的MAC地址的过程与上述的步骤202相似，具体可以参阅上述的步骤202，在此不再赘述。

404、服务器接收网络接入设备发送的接入设备的MAC地址和WIFI热点的MAC地址；

405、若接入设备的MAC地址和WIFI热点的MAC地址属于同一个地址段，服务器确定接入设备为AP设备。
在本实施例中，识别接入设备是否为AP设备的过程主要由服务器来执行，也就是说，网络接入设备主要负责获取接入设备的MAC地址以及WIFI热点的MAC地址，而根据接入设备的MAC地址以及WIFI热点的MAC地址判断接入设备是否为AP设备则由服务器来执行。具体地，服务器确定接入设备是否为AP设备的过程与步骤203类似，在此不再赘述。
在本实施例中，网络接入设备主要根据服务器发送的地址获取请求来获取接入设备的MAC地址和WIFI热点的MAC地址，而根据接入设备的MAC地址和WIFI热点的MAC地址判断接入设备是否为AP设备则由服务器来执行，通过将判断过程转至由具有更高的处理效率的服务器来执行，降低了网络接入设备的负载，同时提高了判断过程的效率。
