运营商可以通过部署无线接入点来实现对不同区域范围进行无线热点覆盖。用户可以通过无线桥接设备接入该区域的无线接入点而访问到网络资源。然而，在网络访问中，所接入的无线接入点可能会出现故障，使得网络访问失败。可更换故障无线接入点，然后更改接入该故障无线接入点的所有无线桥接设备的基本服务集标识(Basic Service Set ID-BSSID)，该BSSID可理解为无线层面所使用的媒体接入控制(MAC)地址。无线桥接设备可通过关联无线接入点的BSSID来接入该无线接入点。
更改接入故障无线接入点的无线桥接设备的BSSID的方式可以为：首先可确定接入该故障无线接入点的所有无线桥接设备，然后手工将每个无线桥接设备关联的故障无线接入点的BSSID，更改为替换该故障无线接入点的新无线接入点的BSSID，即重新关联新无线接入点的BSSID，以使该无线桥接设备接入该新无线接入点。

具体实施方式
下面将结合本公开示例中的附图，对本公开示例中的技术方案进行清楚、完整地描述。
本公开示例提供了一种更新BSSID和连接网络的方法和装置，以实现无需人工干预，自动更新关联的BSSID，降低维护工作量。
需要说明的是，本公开示例所提供的一种更新BSSID的方法，可以应用于无线桥接设备，该无线桥接设备可以例如为无线网桥。该无线桥接设备可通过关联无线接入点的BSSID来接入该无线接入点，进而通过该无线接入点进行网络连接。该无线桥接设备本地存储有最新关联的无线接入点的BSSID、SSID(Service Set Identifier-服务组合识别码)、以及配置信息。该配置信息可以包括该无线接入点的生厂商的标识(来源标识)、BSSID的后三个字节(地址标识)以及该BSSID。该SSID可以认为是一个局域网的名称，SSID技术可以将一个无线局域网分为几个需要不同身份验证的子网络，只有通过身份验证的用户才可以进入相应的子网络，防止未被授权的用户进入本网络。
如图1所示，本公开示例提供的一种更新BSSID的方法，应用于无线桥接设备，可以包括步骤：
S101：该无线桥接设备可接收第一无线接入点发送的接入报文，该接入报文可携带该第一无线接入点的服务组合识别码SSID和基本服务集标识BSSID；
可以理解的是，该无线桥接设备与已关联的第二无线接入点断开连接后，会进入主动扫描阶段。在该主动扫描阶段，无线桥接设备会主动接收第一无线接入点发送的接入报文。其中，该第一无线接入点发送的接入报文中可携带该第一无线接入点的SSID以及BSSID。当然该无线桥接设备可以通过主动扫描同时接收多个无线接入点发送的接入报文。接收到该第一无线接入点发送的接入报文后，该无线桥接设备可解析该接入报文以确定该第一无线接入点的SSID和BSSID。其中，解析该接入报文可以采用现有技术，在此不做赘述。具体的，该接入报文可以为属于管理帧的信标Beacon报文。
S102：该无线桥接设备可判断本地保存的目标SSID是否与接收的该接入报文携带的SSID匹配，如果是，可执行步骤S103；
具体的，接收到第一无线接入点发送的接入报文后，该无线桥接设备可分析该第一无线 接入点发送的接入报文中携带的SSID，判断该无线桥接设备本地保存的目标SSID是否与该SSID匹配。其中，该目标SSID为该无线桥接设备当前关联的第二无线接入点的SSID。无线桥接设备可将所携带SSID与本地保存的目标SSID不匹配的接入报文丢弃，并且可对SSID匹配的接入报文继续进行解析。
S103：该无线桥接设备可判断本地保存的目标BSSID是否与接收的该接入报文携带的BSSID相同，如果不相同，可执行步骤S104；
需要说明的是，在实际应用中，该无线桥接设备与已关联的第二无线接入点断开连接的情况有多种。一种情况为异常断开，如该第二无线接入点出现故障后被移除，导致该无线桥接设备与该第二无线接入点之间的网络连接断开。一种情况为正常断开，如电路断开(停电等)，导致该无线桥接设备与该第二无线接入点之间的网络连接断开，等等。
在确定出接入报文所携带的SSID与该无线桥接设备本地保存的目标SSID匹配后，可从该接入报文中解析出该第一无线接入点的BSSID，并可判断该BSSID与该无线桥接设备本地保存的目标BSSID是否相同，其中，该目标BSSID为该第二无线接入点的BSSID。若相同，则可以确定该接入报文是该已关联的第二无线接入点发送的接入报文。例如，在该无线桥接设备与该第二无线接入点之间的电路出现故障断开时，该无线桥接设备与该第二无线接入点之间的网络连接可能断开。在电路连接被修复之后，该第二无线接入点可重新向该无线桥接设备发送接入报文。此时，无需对已关联的BSSID进行更新，并可以直接向第二无线接入点发送接入请求，与该第二无线接入点进行网络连接。若不相同，则可以继续后续的更新流程。
S104：该无线桥接设备可判断接收的该接入报文中是否携带该第二无线接入点的配置信息，如果携带，可执行步骤S105；
可以理解的是，当确定出该接收的接入报文中携带的BSSID与本地保存的目标BSSID不匹配时，会继续判断该接入报文中是否携带该无线桥接设备自身当前关联的第二无线接入点的配置信息。
当判断该接入报文中未携带该第二无线接入点的配置信息时，有如下两种情况。第一种情况是该接入报文中未携带任何预设配置信息，此时，可以认为该接入报文为与该无线桥接设备当前关联的第二无线接入点设置了相同的SSID的无线接入点、例如设置在同一个基站中的无线接入点发送的。可以理解的是，在实际应用中，为了解决无线信号的覆盖问题，一般可在同一个基站上安装一个以上无线接入点，例如3个无线接入点，该一个以上无线接入点可设置相同的SSID。
另一种情况是该接入报文中携带了预设配置信息，但该预设配置信息与该无线桥接设备本地保存的目标配置信息不匹配，即与无线桥接设备自身当前关联的第二无线接入点的配置信息不匹配。
该无线桥接设备在判断该接入报文中未携带该无线桥接设备自身当前关联的第二无线接入点的配置信息时，可将该接入报文丢弃。
具体的，如果该发送接入报文的无线接入点为替换故障无线接入点的无线接入点，则该接入报文中会携带可表示故障无线接入点的预设配置信息。例如，该预设配置信息中可以包括故障无线接入点的BSSID。当判断该接入报文中是否携带该无线桥接设备当前关联的第二无线接入点的配置信息时，可以包括：
该无线桥接设备可判断该预设BSSID与该无线桥接设备当前关联的该目标BSSID是否相同；
若相同，该无线桥接设备可判断该接入报文中携带所述配置信息；
若不相同，该无线桥接设备可将该接入报文丢弃。
可以理解的是，当该预设BSSID与该无线桥接设备当前关联的目标BSSID相同时，可以表明该预设BSSID即为该第二无线接入点的BSSID，该第一无线接入点为该第二无线接入点的替换无线接入点。若不相同，则表明该第一无线接入点中的预设配置信息中包括的预设BSSID不是该第二无线接入点的BSSID，则可将该接入报文丢弃。
由于该BSSID的位数较多，数据量较大，直接比对该预设BSSID会占用该无线桥接设备的大量资源且浪费时间。为了节省时间和资源，并且减少无线桥接设备的负载压力，还可提出如下方式。
在一个示例中，该第一无线接入点发送的接入报文中携带的预设配置信息，还可以包括预设来源标识和预设地址标识。
在判断所述预设BSSID与所述无线桥接设备当前关联的目标BSSID是否相同的步骤之前，本公开示例所提供的一种更新BSSID的方法还可以包括：
无线桥接设备可判断该预设来源标识、该预设地址标识与本地保存的对应的目标来源标识、目标地址标识是否匹配；
若所述预设来源标识、所述预设地址标识的一者与所述目标来源标识或目标地址标识不匹配，该无线桥接设备可将该接入报文丢弃；
若所述预设来源标识、所述预设地址标识分别与所述目标来源标识或目标地址标识匹配，该无线桥接设备可执行判断该预设BSSID与该无线桥接设备当前关联的该目标BSSID是否相同的步骤。
在判断所接收的接入报文中携带的预设BSSID与所述无线桥接设备当前关联的目标BSSID是否相同之前，可判断该接入报文中预设来源标识和该预设地址标识是否与本地保存的对应的目标来源标识和目标地址标识匹配。如果它们不匹配，则可将该接入报文丢弃。如果它们相匹配，则可针对该接入报文继续对比该预设BSSID与该目标BSSID是否相同，即可确定该接入报文是否携带该无线桥接设备当前关联的第二无线接入点的配置信息。通过先匹配该预设来源标识和该预设地址标识，再对比该预设BSSID的方式可以减少对比数据量，达到节省资源和时间的效果。
在实际应用中，当从替换故障无线接入点的新的无线接入点发送接入报文时，该接入报文中除携带该新的无线接入点的SSID和BSSID外，还携带其所替换的故障无线接入点的信息，即预设配置信息。在本公开示例中该故障无线接入点的信息(预设配置信息)中记录的预设来源标识和预设地址标识分别为该故障无线接入点的生产公司自定义的一个LOGO和该故障无线接入点的MAC地址(BSSID)的最后三个字节。其中，该故障无线接入点即为该无线桥接设备当前关联的第二无线接入点。在实际应用中，该接入报文一般只会携带一个预设配置信息，如果携带多个时，会优先考虑第一个。
当确定从新的无线接入点发送的接入报文携带有该预设配置信息时，首先可分析该预设配置信息的“identification”字段中的内容。可分别使用“sz_logo”和“sz_mac”来保存该无线接入点的生成商的logo和该无线接入点的MAC地址(预设BSSID)的最后三个字节。然后可将“sz_logo”和“sz_mac”与该无线桥接设备中保存的无线桥接设备当前关联的第二无线接入点的配置信息中的目标“sz_logo”(目标来源标识)和目标“sz_mac”(目标地址标识)进行对比。如果其中任何一组不匹配，则可将携带该预设配置信息的接入报文丢弃，如果都匹配成功，则可继续判断预设BSSID与该无线桥接设备当前关联的该目标BSSID是否相同。
举例而言，该无线桥接设备可解析出该预设配置信息中的“identification”字段的内容为“rrr233456”，其中，“sz_logo”为“rrr”，“sz_mac”为“233456”；且解析出该预设配置信息中携带的预设BSSID为08:00:12:23:34:56。该无线桥接设备中保存的目标BSSID为08:00:12:23:34:56，目标来源标识为“rrr”，目标地址标识为“233456”。首先可对比该“sz_logo”和目标来源标识以及“sz_mac”和目标地址标识，可以确定都匹配成功。然后，可继续对比 该预设BSSID与该目标BSSID，确定匹配成功。因此，可以确认该接入报文携带的该预设配置信息为该无线桥接设备当前关联的第二无线接入点的配置信息。当然，可以理解的是，当对比该“sz_logo”和目标来源标识以及“sz_mac”和目标地址标识时，有任何一组不匹配，都会直接将该对应的接入报文丢弃，不再进行后续的该预设BSSID与该目标BSSID的对比。
S105：该无线桥接设备可将该接入报文携带的BSSID保存为目标BSSID。
需要说明的是，当确定出该接入报文中携带该无线桥接设备关联的第二无线接入点的配置信息，该无线桥接设备可将该接入报文中携带的该第一无线接入点的BSSID保存为目标BSSID。
应用本公开示例，首先该无线桥接设备可判断接收的第一无线接入点发送的接入报文所携带的服务组合识别码SSID是否与本地保存的目标SSID、即该无线桥接设备当前关联的第二无线接入点的目标SSID匹配。若是，可继续判断该接入报文携带的BSSID是否与本地保存的目标BSSID、即该第二无线接入点的目标BSSID相同。若不相同，可判断该接入报文中是否携带该第二无线接入点的配置信息。如果携带，可将该接入报文携带的BSSID保存为目标BSSID。以实现无需人工干预，自动更新关联的BSSID，降低管理人员的维护工作量。
在一个示例中，在接收第一无线接入点发送的接入报文之前，该方法还可以包括：断开该无线桥接设备与该第二无线接入点的网络连接。其中，当在设定的时间长度内未接收到该第二无线接入点发送的信息时，表明该无线桥接设备与该第二无线接入点断开。
可以理解的是，无线桥接设备在与无线接入点进行关联并建立网络连接后，不会再接收任何接入报文，只有在与无线接入点断开网络连接时，才会接收接入报文。当该无线桥接设备在设定的时间内未接收到该第二无线接入点发送的信息时，就可以表明该无线桥接设备与该第二无线接入点断开。在实际应用中，该信息可以有多种形式，可以是该第二无线接入点发送的接入报文，也可以是网络数据信息。当然该网络数据信息也可以是以报文的形式发送向该无线桥接设备的，但此时的报文与该接入报文不同，等等。
在另一示例中，为了节省该无线桥接设备本地的资源，减少无线桥接设备的负载压力，该无线桥接设备可以将未携带该无线桥接设备当前关联的第二无线接入点的配置信息的接入报文丢弃。具体的，当判断该接入报文中未携带该无线桥接设备当前关联的第二无线接入点的配置信息时，该方法还可以包括：将该接入报文丢弃，其中，将该接入报文丢弃可以采用现有技术，在此不做赘述。
一方面，如图2所示，本公开示例还提供了一种连接网络的方法，可以应用于无线桥接 设备。在基于该步骤S101～S105所述的更新基本服务集标识BSSID的方法、将所述接入报文中携带的关于所述第一无线接入点的BSSID保存为目标BSSID(S105)之后，可以包括如下步骤。
S106：该无线桥接设备可向第一无线接入点发送接入请求，并可与第一无线接入点建立网络连接。
基于步骤S101～S105，该无线桥接设备更新该目标BSSID后，可以向该第一无线接入点发送接入请求。该第一无线接入点接收到该接入请求后，可以允许该无线桥接设备与自身(第一无线接入点)建立网络连接。应用本公开示例可以更快捷的为与出现故障的无线接入点建立网络连接的无线桥接设备提供网络服务。
一方面，如图3所示，本公开示例还提供了一种更新BSSID的方法，应用于第一无线接入点，该第一无线接入点为替换故障无线接入点的新的无线接入点，可以包括如下步骤。
S301：该第一无线接入点可发送第一接入报文，该第一接入报文携带第一无线接入点的服务组合识别码SSID、基本服务集标识BSSID以及预设配置信息。无线桥接设备接收该第一接入报文后，可根据该第一接入报文，判断是否更新本地已关联的第二无线接入点的BSSID。
可以理解的是，无线桥接设备可根据接收到的该第一接入报文来决定是否更新本地已关联的无线接入点的BSSID。该第一接入报文中携带第一无线接入点的SSID、BSSID以及预设配置信息，使得无线桥接设备可通过该预设配置信息判断该第一无线接入点是否为替换其当前关联的无线接入点的新的无线接入点，以此来判断是否更新本地已关联的第二无线接入点的BSSID(目标BSSID)。
应用本公开示例，该第一无线接入点可发送携带第一无线接入点的SSID、BSSID以及预设配置信息的第一接入报文，以使无线桥接设备根据该第一接入报文，判断是否更新本地已关联的第二无线接入点的BSSID。可以实现该无线桥接设备自动更新已关联的BSSID，无需人工干预，达到节省时间和精力目的。
具体的，如图4所示，基于步骤S301，本公开示例还提供了一种更新BSSID的方法，该方法还可以包括以下步骤。
S401：第一无线接入点可接收无线桥接设备发送的接入请求。
S402：第一无线接入点可根据该无线桥接设备发送的接入请求，与所述无线桥接设备建立网络连接。
S403：第一无线接入点可更新接入的无线桥接设备的数量。
需要说明的是，当无线桥接设备根据第一无线接入点发送的第一接入报文确定当前关联的无线接入点要被替换时，该无线桥接设备可将本地关联(保存)的目标BSSID更新为该第一接入报文中携带的该第一无线接入点的BSSID。同时，该无线桥接设备可向该第一无线接入点发送一个接入请求，该第一无线接入点可根据该接入请求，与该无线桥接设备建立网络连接。并且，为了便于该第一无线接入点确定是否可以发送第一接入报文，在与无线桥接设备建立网络连接后，该第一无线接入点可更新所接入的无线桥接设备的数量。通过限制接入的无线桥接设备的数量，可避免因该第一无线接入点接入的无线桥接设备的数量过多而影响该第一无线接入点自身的性能。
具体的，该携带预设配置信息的第一接入报文与未携带预设配置信息的第二接入报文不同。该携带预设配置信息的第一接入报文是替换掉故障无线接入点的新的无线接入点在满足一定条件下所发出的。而第二接入报文可以是任何无线接入点发出的，其中，该任何无线接入点包括该新的无线接入点。具体的，如图3所示，在所述发送第一接入报文(S301)之前，本公开示例所提供的一种更新BSSID的方法还可以包括：
S302：该第一无线接入点可判断是否符合发送该第一接入报文的预定条件，若符合，执行步骤S301，其中，该预定条件包括：接入该第一无线接入点的无线桥接设备的数量未达到预设的目标数量，和/或自该第一无线接入点被配置生效开始到该第一无线接入点发送第一接入报文的时长未超过预设时长。
该第一无线接入点配置完成后，可以首先判断自身是否符合发送第一接入报文的预定条件，若符合，发送该第一接入报文，若不符合，发送第二接入报文。其中该预定条件可被预先设置。
需要说明的是，当接入该第一无线接入点的无线桥接设备的数量未达到预设的目标数量，可以以广播的形式发送第一接入报文。或者，自该第一无线接入点被配置生效开始到发送第一接入报文的时长未超过预设时长，可以发送第一接入报文。对于同时设置预设目标数量和预设时长的情况下，如果经过了预设时长，且接入该第一无线接入点的无线桥接设备的数量未达到预设的目标数量，该第一无线接入点可以不再发送第一接入报文。此时，可以重新设置该第一无线接入点的预定条件，或者手动将未接入的无线桥接设备接入该第一无线接入点。另外的，如果在预设时长内，接入该第一无线接入点的无线桥接设备的数量已达到预设的目标数量，此时，该第一无线接入点可以不再发送第一接入报文，也可以继续发送第一接入报文，直到达到预设时长时才会停止发送第一接入报文。
具体的，为了及时地检测该第一无线接入点是否符合预定条件，智能地控制该第一无线接入点发送第一接入报文，本公开示例所提供的一种更新BSSID的方法，还可以包括：在该无线桥接设备与该第一无线接入点建立网络连接后，更新接入该第一无线接入点的无线桥接设备的数量。
具体的，如图3所示，当判断不符合发送该第一接入报文的预定条件时，本公开示例所提供的一种更新BSSID的方法还可以包括：
S303：该第一无线接入点可发送第二接入报文，该第二接入报文携带该第一无线接入点的服务组合识别码SSID和基本服务集标识BSSID。
需要说明的是，当不符合发送第一接入报文的预定条件时，理论上可以表明该第一无线接入点中已经接入预设的目标数量的无线桥接设备，该第一无线接入点不再希望接入无线桥接设备。此时，该第一无线接入点会继续发送仅携带自身SSID和BSSID的第二接入报文。在实际应用中，当该无线桥接设备与当前关联的无线接入点由于断电等正常原因而断开连接时，可以通过该第二接入报文，重新相互建立网络连接。
一方面，相应于上述方法示例，本公开示例还提供了一种无线桥接设备，如图5所示，所述无线桥接设备500可以包括：存储介质510、处理器520、通信接口530以及将存储介质510、处理器520和通信接口530耦合在一起的耦合机构540。存储介质510可存储由处理器520执行的多个机器可读指令模块。所述机器可读指令模块可包括：报文接收模块501、SSID判断模块502、BSSID判断模块503、配置信息判断模块504和保存模块505。
