背景技术
WLAN(Wireless Local Area Network，无线局域网)技术是当今通信领域的热点之一。和有线相比，无线局域网的启动和实施相对简单，维护的成本低廉。WLAN中，可以通过无线路由设备来提供无线覆盖。但是，在实际的应用场景中，由于墙体等遮挡物的存在，可能会导致房屋的部分区域存在无线覆盖盲点。
为了解决上述问题，可以在无线路由设备与无线覆盖盲点区域之间，增加无线中继设备。通过无线中继设备对无线路由设备的无线信号的中继，可以扩大无线路由设备的无线覆盖范围，达到扫除无线覆盖盲点的目的。

具体实施方式
无线路由设备可按照预定信标时间间隔向无线中继设备发送信标(Beacon)报文，其中，该Beacon报文中可携带有SSID(Service Set Identifier，服务集标识)等。无线中继设备监听到该Beacon报文之后，可将该Beacon报文中携带的SSID添加到无线信道列表中。从而，无线中继设备可以将监听到的多个Beacon报文中携带的SSID添加到无线信道列表中。
无线中继设备可从无线信道列表中选择一个SSID，根据该SSID向对应的无线路由设备发送Probe Request(探测请求)报文。无线路由设备接收到该Probe Request报文之后，可向无线中继设备发送Probe Response(探测响应)报文，从而完成探测过程。在完成认证过程和关联过程之后，无线中继设备与无线路由设备建立连接，实现了对无线路由设备的无线信号的中继。
图1是本公开一示例示出的无线中继实现方法的交互流程图。如图1所示，在本公开示例中，无线中继实现方法可包括以下步骤S101-S108。
在步骤S101，无线中继设备可以发送Probe Request报文，其中，所述Probe Request报文携带有第一检测码和所述无线中继设备的设备信息。
无线中继设备上电启动后，如果判断出当前配置为默认配置，则可以按照预定发送时间间隔T1，在本设备支持的ISM(Industrial Scientific Medical，工业科学医学)频段内发送Probe Request报文。其中，ISM频段可为2.4GHz(吉赫兹)和5GHz。
在实际实施过程中，如果Probe Request报文发送过快，可能会占用较多资源。如果Probe Request报文发送过慢，可能会使得完成无线中继过程的时间过长。因此，可将上述发送时间间隔T1设置为60秒。
其中，无线中继设备中可保存有多个检测码。检测码可是一个由多个字节组成的字符串。在无线中继设备发送Probe Request报文之前，可以选择一个检测码作为第一检测码。例如，可选择“H3C_MAGIC”作为第一检测码。该无线中继设备可发送携带有选中的检测码、例 如第一检测码和所述无线中继设备的设备信息的Probe Request报文。
在其中一个实施方式中，每一个检测码可有对应的加密算法。例如，检测码“H3C_MAGIC”对应的加密算法可为AES(Advanced Encryption Standard，高级加密标准)加密算法，检测码“H3C”对应的加密算法可为DES(Data Encryption Standard，数据加密标准)加密算法。无线中继设备可使用选中的检测码、例如“H3C_MAGIC”对应的加密算法、例如AES加密算法对该无线中继设备的设备信息进行加密，得到密文的设备信息。该无线中继设备可发送携带有选中的检测码、例如第一检测码和密文的设备信息的Probe Request报文。当然，该无线中继设备的设备信息也可不进行加密，例如当第一检测码没有对应的加密算法时。
上述设备信息可以是MAC(Media Access Control，媒体访问控制)地址、电子标签和设备型号等信息中的一种或多种的组合。
在步骤S102，无线路由设备在接收到该Probe Request报文之后，可根据该Probe Request报文中携带的第一检测码和该无线中继设备的设备信息，判断是否允许该无线中继设备自动连接本无线路由设备，并在确定出允许时，向该无线中继设备发送Probe Response报文。
如图1所示，可能会有多个无线路由设备，例如无线路由设备1、无线路由设备2、…、无线路由设备M，M为大于1的整数，接收到该无线中继设备发出的Probe Request报文，因此，每一个无线路由设备均可执行上述步骤S102。
在步骤S102中，无线路由设备根据第一检测码和该无线中继设备的设备信息，判断是否允许无线中继设备自动连接本无线路由设备的方法可如图2所示，可以包括以下步骤S201-S204。
在步骤S201，判断本无线路由设备上是否存在与第一检测码相同的检测码。若存在，则执行步骤S202。若不存在，则执行步骤S204。
其中，无线路由设备上也可保存多个检测码，这些检测码可与无线中继设备上保存的检测码相同。
在步骤S202，本无线路由设备判断无线中继设备的设备信息是否正确。若正确，则执行步骤S203，否则执行步骤S204。
当无线中继设备的设备信息被第一检测码对应的加密算法加密时，无线路由设备为了从Probe Request报文中获取到无线中继设备的设备信息，可以查找第一检测码对应的加密算法并使用查找到的加密算法对应的解密算法，对该Probe Request报文中携带的密文的无线中继设备的设备信息进行解密，从而得到明文的无线中继设备的设备信息。而当无线中继设备的 设备信息没有被第一检测码对应的加密算法加密时，无线路由设备可从Probe Request报文中直接获取到明文的无线中继设备的设备信息。之后，无线路由设备可判断该明文的无线中继设备的信息是否正确。这样，可起到安全认证的作用。
无线路由设备判断该无线中继设备的信息是否正确，可以采用如下方法中的一种或多种的组合。
方法一：当无线中继设备的设备信息是MAC地址时，无线路由设备可将该MAC地址与MAC Header(MAC头)的Source MAC(源MAC)字段中携带的MAC地址进行比较。若两者相同，则确定该无线中继设备的设备信息正确。
方法二：当无线中继设备的设备信息是MAC地址、电子标签、设备型号等信息中的一种或多种组合时，无线路由设备可将无线中继设备的这些设备信息发送给云端服务器，以便查询这些设备信息的正确性。当无线路由设备接收到云端服务器返回的认证结果之后，可以获知这些设备信息是否正确。
在实际实施过程中，还可以使用其它的判断方法。例如，当无线中继设备的设备信息是电子标签时，无线中继设备可在Probe Request报文中增加一个用于携带电子标签的字段，以使无线路由设备可以比较该字段中携带的电子标签与该设备信息中的电子标签。或者，当无线中继设备的设备信息是设备型号时，无线中继设备可在Probe Request报文中增加一个用于携带设备型号的字段，以使无线路由设备可以比较该字段中携带的设备型号与该设备信息中的设备型号，本公开实施例对此不做限定。
在步骤S203，无线路由设备允许该无线中继设备自动连接本无线路由设备。
在步骤S204，无线路由设备不允许该无线中继设备自动连接本无线路由设备。
无线路由设备可以根据第一检测码和无线中继设备的设备信息，判断是否允许无线中继设备自动连接本无线路由设备。该Probe Request报文还可以携带有RSSI(Received Signal Strength Indication，接收信号强度指示)值。无线路由设备还可以根据该Probe Request报文中携带的RSSI值判断是否允许无线中继设备自动连接本无线路由设备，该判断方法可如图3所示包括以下步骤S301～S305。
在步骤S301，无线路由设备判断本设备上是否存在与该Probe Request报文中携带的第一检测码相同的检测码。若存在，则执行步骤S302。若不存在，则执行步骤S305。
在步骤S302，无线路由设备判断该Probe Request报文中携带的无线中继设备的设备信息是否正确。若正确，则执行步骤S303，否则，执行步骤S305。
在步骤S303，无线路由设备判断该Probe Request报文中携带的RSSI值是否大于预定强度阈值。若大于，则执行步骤S304，否则，执行步骤S305。
在一示例中，该Probe Request报文的Packet Information(报文信息)字段可以携带RSSI值。
在步骤S304，无线路由设备允许该无线中继设备自动连接本无线路由设备。
在步骤S305，无线路由设备不允许该无线中继设备自动连接本无线路由设备。
在如图3所示的方法中，在无线路由设备判断是否允许无线中继设备自动连接本无线路由设备时，增加判断RSSI值的目的是避免在有多个无线路由设备的环境中，无线中继设备错误的中继其它无线路由设备的无线信号。上述的预定强度阈值可以设置为-65dBm，对应的无遮挡直线距离约为2米。例如，如果无线路由设备判断出该Probe Request报文中携带的RSSI值大于-65dBm，可以允许该无线中继设备自动连接本无线路由设备，表明无线路由设备仅允许物理距离在约2米范围内的无线中继设备自动连接本无线路由设备。
进一步，在无线路由设备判断是否允许无线中继设备自动连接本无线路由设备时，增加判断RSSI值的目的还可包括：即使加密算法被破解，但是如果无线中继设备在物理距离上无法靠近无线路由设备，则该无线中继设备仍然无法自动连接该无线路由设备。
假如，图1中的无线路由设备1、无线路由设备2和无线路由设备M均允许该无线中继设备自动连接，则这些无线路由设备都可以向该无线中继设备发送Probe Response报文。其中，该Probe Response报文中可以携带第二检测码、该无线路由设备对应的SSID、密码和无线参数等。其中，无线参数可以包括：RSSI值、信道频宽模式、无线信道、信号质量(CINR(Carrier to Interference plus Noise Ratio，载波与干扰和噪声比)/SINR(Signal to Interference plus Noise Ratio，信号与干扰和噪声比))、时间偏移(timing offset)、频率偏移(frequency offset)、终端信号入射角度、无线中继方式、物理速率等参数中的一种或多种的组合。无线参数还可以包括其它参数，本公开实施例对此不做限定。
其中，信道频宽模式可以是HT(High Throughput，高吞吐量)20、HT40、HT80、或HT160等。
无线中继方式可以是单频或双频。当无线路由设备支持双频，无线中继设备也支持双频时，无线路由设备可以指定无线中继设备的无线中继方式。例如，无线路由设备可以指定该无线中继设备以双频方式中继该无线路由设备的无线信号，还可以进一步指定该无线中继设备与该无线路由设备进行数据传输所使用的第一频段以及该无线中继设备与无线客户端进行 数据传输所使用的第二频段。例如，第一频段可以是2.4GHz、第二频段可以是5GHz，或者，第一频段可以是5GHz、第二频段可以是2.4GHz。在一示例中，无线中继设备可以使用第一频段进行无线中继，使用第二频段进行无线覆盖。
无线路由设备在发送Probe Response报文之前，选择一个检测码作为第二检测码。例如，无线路由设备可选择“H3C_MAGIC”作为第二检测码，使用选中的检测码“H3C_MAGIC”对应的AES加密算法对SSID、密码和无线参数进行加密，得到密文的SSID、密码和无线参数等。无线路由设备可发送携带有选中的检测码(即第二检测码)和密文的SSID、密码和无线参数等的Probe Response报文。Probe Response报文中的第二检测码与Probe Request报文中的第一检测码可以相同，也可以不同。如果第二检测码没有对应的加密算法，SSID、密码和无线参数也可不进行加密。
在步骤S103，无线中继设备接收无线路由设备发送的Probe Response报文。
无线中继设备在接收到任一Probe Response报文之后，可判断本设备上是否存在与该Probe Response报文中携带的第二检测码相同的检测码。若存在，则可以从该Probe Response报文中获取SSID、密码和无线参数。例如，当SSID、密码和无线参数被第二检测码对应的加密算法加密时，该无线中继设备可查找所述第二检测码对应的加密算法，并使用查找到的加密算法对应的解密算法，对该Probe Response报文中携带的密文的SSID、密码和无线参数进行解密，从而得到明文的SSID、密码和无线参数。
在步骤S104，若在预定等待时间T2内无线中继设备接收到两个以上无线路由设备发送的Probe Response报文，则无线中继设备可选择一个无线路由设备。
在预定等待时间T2到达时，此时无线中继设备可能会获取到多个SSID、密码和无线参数。在这种情况下，无线中继设备可选择满足预设条件的无线参数对应的SSID和密码，为了描述方便，可称为第一SSID和第一密码。无线中继设备可选择发出携带有第一SSID和第一密码的Probe Response报文的无线路由设备。
由于无线参数可以包括RSSI值、信道频宽模式、无线信道、信号质量(CINR/SINR)、时间偏移、频率偏移、终端信号入射角度、无线中继方式、物理速率等参数中的一种或多种的组合，从而，上述预设条件可以结合上述参数中的一种或多种的组合进行设定。例如，当无线参数为RSSI值时，上述预设条件可以为RSSI值大于预定强度阈值，本公开实施例对此不做限定。
另外，在实际实施过程中，如果预定等待时间T2过短，则无线中继设备可能会无法连接 到理想的无线路由设备。如果预定等待时间T2过长，可能会使得完成无线中继过程的时间太长。因此，优选的，可将等待时间T2设置为60秒。
假设，在步骤S104中，无线中继设备选择的是图1中的无线路由设备2。
在步骤S105，无线中继设备向选中的无线路由设备(无线路由设备2)发送Authentication Request(认证请求)报文。其中，该Authentication Request报文中可携带该选中的无线路由设备发送的Probe Response报文中携带的第一SSID和第一密码。
在步骤S106，选中的无线路由设备接收到该Authentication Request报文之后，根据第一SSID和第一密码对该无线中继设备进行认证，并在认证通过后向该无线中继设备发送Authentication Response(认证响应)报文。
在步骤S107，无线中继设备接收到该Authentication Response报文之后，向选中的无线路由设备发送Association Request(关联请求)报文。
在步骤S108，选中的无线路由设备接收到该Association Request报文之后，向该无线中继设备发送Association Response(关联响应)报文。
该无线中继设备接收到该Association Response报文之后，即与该选中的无线路由设备建立了连接，可以对该选中的无线路由设备的无线信号进行中继。
另外，该无线中继设备接收到该Association Response报文之后，还可以将本设备设置为Client(客户端)模式，按照满足上述预设条件的无线参数进行无线设置，并将该无线参数保存在非默认配置的配置文件中。此时，该无线中继设备的当前配置可更新为非默认配置。这样，当该无线中继设备再次上电启动时，由于用于指示启动位置的指针指向保存有该配置文件的内存空间，因此，可以按照该配置文件直接进行无线设置，从而可实现对该选中的无线路由设备的无线信号的中继。
在图1所示的无线中继实现方法中，当无线中继设备只接收到一个无线路由设备响应的Probe Response报文时，无线中继设备可不执行步骤S104的选择操作，而直接与该无线路由设备进行步骤S105～步骤S108的认证和关联过程。
在上述方法中，无线中继设备在中继成功之后，可以发出指示信号，用于表示中继成功。例如，无线中继设备可以通过LED(Light emitting diode，发光二极管)指示灯发出指示信号，或者，通过声音发出指示信号等，本公开实施例对此不做限定。
本公开实施例的上述方法中，无线中继设备可以向第一无线路由设备发送携带有第一检 测码和该无线中继设备的设备信息的Probe Request报文。所述第一无线路由设备接收到该Probe Request报文之后，会根据第一检测码和该设备信息，判断是否允许该无线中继设备自动连接本无线路由设备。第一无线路由设备在确定出允许自动连接时向该无线中继设备发送携带有所述第一无线路由设备对应的SSID和密码的Probe Response报文。该无线中继设备可以接收到多个第一无线路由设备发送的Probe Response报文，并向第二无线路由设备发送携带有所述第二无线路由设备对应的SSID和密码的Authentication Request报文，以能够实现对所述第二无线路由设备的无线信号的中继。可以理解的是，所述第二无线路由设备是所述第一无线路由设备中的一个。在上述过程中，无线中继设备与无线路由设备之间可以自动发现和协商，从而实现了一种简单快捷的无线中继实现方法，达到了简化配置和优化网络的目的。
在一示例中，所述无线中继设备可以在发送所述Probe Request报文起等待预定时间，当预定时间到达时，根据在所述预定时间内接收到的Probe Response报文，选择发送所述Probe Response报文的所述第一无线路由设备中的一个作为所述第二无线路由设备。其中，所述Probe Response报文中还携带有第二检测码和无线参数；所述无线中继设备中存在与所述第二无线路由设备发送的Probe Response报文中携带的第二检测码相同的检测码。
在另一示例中，在所述预定时间到达时，所述无线中继设备从接收到的Probe Response报文中选择所携带的无线参数满足预设条件的第一Probe Response报文；所述无线中继设备选择发出所述第一探测响应报文的无线路由设备作为所述第二无线路由设备。
在一示例中，从接收到的探测响应报文中选择所携带的无线参数满足预设条件的第一探测响应报文可以包括：所述无线中继设备查找所接收到的探测响应报文中携带的第二检测码对应的加密算法；所述无线中继设备使用查找到的加密算法对应的解密算法，对所接收到的探测响应报文中携带的密文的SSID、密码和无线参数进行解密，得到明文的SSID、密码和无线参数；并且所述无线中继设备选择所携带的无线参数满足预设条件的探测响应报文作为所述第一探测响应报文。

本公开第二无线中继实现装置的实施例可以应用在无线路由设备上。第二无线中继实现装置实施例可以通过软件实现，也可以通过硬件或者软硬件结合的方式实现。以软件实现为例，作为一个逻辑意义上的装置，第二无线中继装置可以理解为存储在机器可读存储介质中的机器可读指令。从硬件层面而言，如图8所示，为本公开无线路由设备的一种硬件结构图，除了图8所示的处理器81、内部总线82、网络接口83以及机器可读存储介质84之外，该无线路由设备还可以包括其他硬件以实现例如通用无线路由等的其他功能，对此不再赘述。
在不同的实施例中，所述机器可读存储介质84可以是：RAM(Radom Access Memory，随机存取存储器)、易失存储器、非易失性存储器、闪存、存储驱动器(如硬盘驱动器)、固态硬盘、任何类型的存储盘(如光盘、DVD等)，或者类似的存储介质，或者它们的组合。
进一步，机器可读存储介质84上可存储由处理器81执行的第二无线中继实现装置90对应的机器可读指令。请参考图9，图9是本公开一示例示出的应用于无线路由设备中的第二无线中继实现装置的一种结构示意图。从功能上划分，所述第二无线中继实现装置90可包括以下模块：第一接收模块901、第一判断模块902、发送模块903、第二接收模块904和认证模块905。
第一接收模块901可被配置为接收无线中继设备发送的携带有第一检测码和无线中继设备的设备信息的Probe Request报文。
