在无线局域网(wireless local area network，WLAN)中，站点(station，STA)在接入WLAN时，接入点(access point，AP)会为STA分配一个关联标识符(association identifier，AID)，该AID用于标识该STA与该AP已建立对应关系，该STA与该AP可以进行通信，通常AP在为STA分配AID时，按照从1开始逐渐递增的顺序分配给STA。
在传统的组网中，每个AP的基本服务集标识符(basic service set identifier，BSSID)独立，每个AP各自管理自身关联的STA的AID。由于AP为其关联的STA分配的AID唯一，所以在一个BSSID标识的网络架构中，AID也可以在某些消息中代替媒体访问控制(media access control，MAC)地址对STA进行标识。例如，用AID区分对应STA的调度信息。
然而随着通信技术的发展，出现多个AP共用一个BSSID的网络架构，若还使用传统的分配方式进行AID的分配(如在该网络架构中多个AP分别为接入自己的AP分配AID)，则有可能会使得两个AP为不同STA分配相同的AID。这样，由于在一个BSSID标识的网络架构中存在相同AID的STA，所以在STA发送携带AID的消息给AP且未携带源MAC地址时，会导致AP无法区分STA。
发明内容
本申请提供了一种分配AID的方法、装置、系统、设备和存储介质，解决了在一个BSSID标识的网络架构中AP无法区分STA的问题。
第一方面，本申请提供了一种分配AID方法，该方法由管理设备执行，该方法包括：
管理设备获取STA的参数；该管理设备基于该STA的参数，为该STA分配AID，并在该管理设备管理的多个AP中确定第一AP，该第一AP用于向该STA发送该AID，该多个AP的BSSID相同，该多个AP中至少一个AP接收到该STA发送的认证请求，该第一AP属于该至少一个AP；该管理设备向该第一AP发送该AID和该STA的标识。
本申请所示的方案，管理设备使用STA的参数，为STA分配AID。管理设备确定向STA发送AID的第一AP，管理设备向第一AP发送AID和STA的标识，使得第一AP向STA发送AID。这样，在多个AP共用一个BSSID的网络架构中，由管理设备统一为STA分配AID，使得为该网络架构下各STA分配的AID不相同，进而使得在STA发送携带AID的消息给AP且未携带源MAC地址时，也可以使用AID区分STA。
在一种可能的实现方式中，该方法还包括：该管理设备向该多个AP中除该第一AP之外的其它AP发送该AID和该STA的标识。这样，由于其它AP中也会记录AID与该STA对 应，所以在该STA漫游至其它AP后，不需要重新进行认证以及关联，可以节约接入网络时长。
在一种可能的实现方式中，该方法还包括：该管理设备检测到该STA离线；该管理设备向该多个AP分别发送回收消息，该回收消息用于指示回收该AID。
本申请所示的方案，在STA离线后，管理设备可以通知各个AP回收该STA对应的AID，使得后续该AID可以被分配给其它STA，节约AID的资源。
在一种可能的实现方式中，该多个AP与该管理设备形成光纤到房间(fiber to the room，FTTR)的网络架构，该管理设备通过分配消息携带该AID和该STA的标识，该AID和该STA的标识位于该分配消息的载荷字段中，该分配消息的目的地址为接收该分配消息的AP的标识。其中，每个AP的标识用于唯一标识该AP。
在一种可能的实现方式中，该多个AP与该管理设备形成以太网架构，该管理设备通过以太网帧携带该AID和该STA的标识，该AID和该STA的标识位于该以太网帧的载荷字段中。
在一种可能的实现方式中，该多个AP与该管理设备形成无源光网络(passive optical network，PON)的架构，该管理设备通过光网络单元管理控制接口(ONU management and control interface，OMCI)消息携带该AID和该STA的标识，该AID和该STA的标识位于该OMCI消息的消息内容字段中。
在一种可能的实现方式中，该管理设备获取STA的参数，包括：该管理设备接收该多个AP中至少一个AP发送的认证上报消息，该认证上报消息包括该STA的参数；该管理设备从该认证上报消息中，获取该STA的参数。这样，管理设备可以从认证上报消息中，获取STA的参数。
在一种可能的实现方式中，该方法还包括：该管理设备获取该至少一个AP的特征信息，每个AP的特征信息包括负载信息、受到的干扰信息和接收该STA发送的信号的质量信息中的至少一种；该在该管理设备管理的多个AP中确定第一AP，包括：该管理设备基于该至少一个AP的特征信息，确定该至少一个AP分别与该STA的连接质量，将该至少一个AP中连接质量最高的AP确定为第一AP。
本申请所示的方案，管理设备使用至少一个AP的特征信息，在该至少一个AP中，确定连接质量最高的AP，作为STA待关联的AP。这样，至少一个AP为向管理设备发送认证上报消息的AP，也就是说至少一个AP为接收到STA发送的认证请求的AP，那么该至少一个AP中每个AP均能与STA进行通信，在这些AP中选取出连接质量最高的AP，能够使得选取到的AP能够与STA进行通信。
在一种可能的实现方式中，该方法还包括：该管理设备检测到该STA从该第一AP的覆盖范围内移动至该多个AP中第二AP的覆盖范围内；该管理设备向该第二AP发送通知消息，该通知消息用于指示该第二AP与该STA进行连接。这样，在STA漫游至第二AP的覆盖范围内后，管理设备可以通知第二AP为STA提供转发报文的功能，使得STA不会感知切换AP。
第二方面，本申请提供了一种分配AID的方法，该方法由第一AP执行，该方法包括：
第一AP接收管理设备发送的AID和STA的标识，该AID为该管理设备为该STA分配的AID；该第一AP将该STA的标识和该AID对应存储。
本申请所示的方案，在多个AP共用一个BSSID的网络架构中，由管理设备统一为STA分配AID，使得为该网络架构下各STA分配的AID不相同，进而使得在STA发送携带AID 的消息给AP且未携带源MAC地址时，也可以使用AID区分STA。
在一种可能的实现方式中，该方法还包括：在该第一AP为该管理设备指定的与该STA关联的AP的情况下，该第一AP向该STA发送该AID。这样，管理设备指定的AP向STA发送AID，不仅使得STA能够获取到自身对应的AID，而且不会重复接收到AID。
在一种可能的实现方式中，该第一AP接收管理设备发送的AID和STA的标识之前，还包括：该第一AP接收该STA发送的认证请求，该认证请求包括该STA的参数；该第一AP向该管理设备发送认证上报消息，该认证上报消息包括该STA的参数；该第一AP接收管理设备发送的AID和STA的标识之后，还包括：在该第一AP为该管理设备指定的与该STA关联的AP的情况下，该第一AP向该STA发送认证响应消息。
本申请所示的方案，在第一AP接收到STA发送的认证请求后，通报给管理设备，使得管理设备为STA分配AID，并且在第一AP被指定为与该STA关联的AP的情况下，向STA发送认证响应消息，使得STA能够继续执行接入网络的过程。而且仅由与该STA关联的AP向STA发送认证响应消息，使得STA不会重复接收到认证响应消息。
在一种可能的实现方式中，该方法还包括：该第一AP接收该管理设备发送的回收消息，该回收消息用于指示回收该AID；该第一AP回收该AID。
本申请所示的方案，在第一AP接收到AID的回收消息后，回收AID，使得AID还能够被分配给其它STA，节约AID的资源。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
下面描述相关技术的方案。
相关技术中，在传统的组网中，每个BSSID标识一个网络架构，在每个网络架构中包括一个AP，每个网络架构中的AP各自管理自身关联的STA的AID。由于AP为其关联的STA分配的AID唯一，所以在一个BSSID标识的网络架构中，AID也可以在某些消息中代替MAC 地址对STA进行标识。例如，如图1所示，三个网络架构分别包括AP1、AP2和AP3，AP1为STA1分配AID1，AP1为STA2分配AID2，AP2为STA3分配AID1，AP3为STA4分配AID1，AP3为STA5分配AID2。由于AP1和AP2的BSSID不相同，所以即使STA1与STA3在发送的消息中仅携带AID1，也不会混淆。
然而随着通信技术的发展，出现多个AP共用一个BSSID的网络架构，若该网络架构中多个AP分别为接入自己的STA分配AID，则有可能会使得两个AP为不同STA分配相同的AID。这样，由于在一个BSSID标识的网络架构中存在相同AID的STA，所以在STA发送携带AID的消息给AP且未携带源MAC地址时，会导致AP无法区分STA，并且在AP向自身关联的STA发送携带AID的消息时，STA侧将发生混淆。例如，如图2所示，在一个网络架构下包括AP4和AP5，AP4为STA6分配AID1，AP5为STA7分配AID1，AP5为STA8分配AID2。由于一个BSSID标识的网络架构下，各个AP的MAC地址相同，所以STA6发送带AID1且未携带源MAC地址的消息时，AP4和AP5均会收到该消息时，无法区分该消息属于STA6还是STA7。AP4发送信标(beacon)帧，指示AID1的STA6有数据待传输，STA6的休眠将被唤醒，同时STA7会误认为自身也有数据待传输，休眠也将被唤醒，影响节能效率。
本申请中，在多个AP共用一个BSSID的网络架构中，由管理设备统一为STA分配AID，使得为该网络架构下各STA分配的AID不相同，进而使得在STA发送携带AID的消息给AP且未携带源MAC地址时，也可以使用AID区分STA。
下面，按照分配AID的系统、系统中各类设备的硬件结构、分配AID的方法的顺序，从多个角度对本申请实施例提供的技术方案进行具体描述。
以下介绍本申请实施例提供的分配AID的系统。
参见图3，本申请实施例提供了一种分配AID的系统300。系统300包括多个AP301和管理设备302。多个AP301组成一个网络架构，在该网络架构中，AP301的BSSID相同，各AP301的MAC地址相同，相邻的两个AP301的覆盖范围可以有重叠，也可以没有重叠。例如，AP301可以是路由器、交换机或光锚等。管理设备302用于分配AID，管理设备302可以是网络架构中的某个AP，该AP称为是中心AP，如网络架构中能力最强的AP等，也可以是负责管理多个AP301的接入控制器等。其中，本申请实施例不对AP的数目和类型进行限制。
管理设备302与每个AP301能够通信，如通过光纤通信、通过线缆通信或通过无线通信等。在一种实现中，管理设备302与多个AP301形成FTTR的网络架构，管理设备302为光网关，多个AP301为边缘AP，边缘AP用于供STA接入，光网关与边缘AP之间通过光纤连接、通过无线连接或通过线缆连接。在另一种实现中，管理设备302与多个AP301形成以太网的架构。在另一种实现中，管理设备302与多个AP301形成PON的架构，管理设备302与多个AP301通过光纤连接。此处描述管理设备302与多个AP301形成PON的架构，是说明管理设备302和多个AP301之间的网络架构类似于PON。
上面介绍了本申请实施例提供的系统架构，下面对上述系统架构中设备的硬件结构进行介绍。
请参见图4，图4所示的设备400是对上述系统架构中AP301以及管理设备302的举例说明。可选地，设备400配置为AP301和管理设备302等。

存储器403例如是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其它类型的静态存储设备，又如是随机存取存储器(random access memory，RAM)或者可存储信息和指令的其它类型的动态存储设备，又如是电可擦可编程只读存储器(electrically erasable programmable read-only Memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其它光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其它磁存储设备，或者是能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其它介质，但不限于此。存储器403例如是独立存在，并通过通信总线402与处理器401相连接。存储器403也可以和处理器401集成在一起。
可选地，存储器403用于保存设备400为SAT分配的AID等。
网络接口404使用任何收发器一类的装置，用于与其它设备或通信网络通信。网络接口404包括有线网络接口，还可以包括无线网络接口。其中，有线网络接口例如可以为以太网接口。以太网接口可以是光接口，电接口或其组合。无线网络接口可以为WLAN接口，蜂窝网络网络接口或其组合等。
在具体实现中，作为一种实施例，处理器401可以包括一个或多个CPU。
在具体实现中，作为一种实施例，设备400可以包括多个处理器。这些处理器中的每一个可以是一个单核处理器(single-CPU)，也可以是一个多核处理器(multi-CPU)。这里的处理器可以指一个或多个设备、电路、和/或用于处理数据(如计算机程序指令)的处理核。
在一些实施例中，存储器403用于存储执行本申请方案的程序代码4031，程序代码4031为计算机指令，处理器401可以执行存储器403中存储的程序代码4031。也即是，设备400可以通过处理器401以及存储器403中的程序代码4031，来实现方法实施例提供的分配AID的方法。
在另一种实现方式中，图5示出了AP301的结构示意图，AP301包括主控板3011和接口板3012，主控板3011属于AP301的控制面，接口板3012属于AP301的数据面。主控板3011包括处理器和存储器。接口板3012包括处理器、存储器和接口卡。

下面描述本申请实施例中分配AID的方法流程中管理设备的处理，参见图6中步骤601至步骤603。在后文中，AP为AP301，管理设备为管理设备302。
步骤601，管理设备获取STA的参数。
其中，STA为任一请求接入AP的设备，如手机、平板、音箱或笔记本等。
在本实施例中，管理设备确定STA请求认证，获取STA的参数，该参数包括但不限于STA的能力等级和型号等。
步骤602，管理设备基于STA的参数，为STA分配AID，并在管理设备管理的多个AP中确定第一AP，第一AP用于向STA发送该AID，多个AP的基本服务集标识符BSSID相同，多个AP中至少一个AP接收到STA发送的认证请求。
在本实施例中，管理设备校验STA的参数，判断是否准许STA上线，如管理设备判断STA的型号是否属于准许接入的型号，并且判断STA的能力等级是否符合管理设备所要求的能力等级，若二者均符合，则确定准许STA上线，否则不准许STA上线。若准许STA上线，则为STA分配AID，为了方便描述该AID称为是目标AID，如管理设备在当前未分配的AID中选取序号最小的AID。若不准许STA上线，则管理设备向接收到认证请求的某个AP发送认证失败消息，以使得该AP向STA发送认证响应消息，该认证响应消息指示认证失败。
并且管理设备在自身管理的多个AP中，确定第一AP，第一AP作为STA待关联的AP，第一AP用于向STA发送目标AID。在管理设备为中心AP时，若中心AP确定自身是第一AP，则可以不执行步骤603。
可选的，管理设备在分配AID时，可以按照STA的接入顺序由小到大分配，AID的范围为1至2007，每个AID对应一个可用标记位，该标记位默认置为1。在目标AID被分配给STA后，目标AID的标记位置为0。这样，管理设备在为STA分配AID时，是分配标记位置为1的AID，使得同一时刻不存在使用相同AID的STA。
需要说明的是，多个AP为STA有可能会接入的AP。另外，由于选取的第一AP是为了与STA通信，所以当前应该能与STA进行通信，那么第一AP属于接收到STA发送的认证请求的AP。
步骤603，管理设备向第一AP发送该AID和STA的标识。
在本实施例中，管理设备确定出目标AID和第一AP后，向第一AP发送目标AID和STA的标识，其中，STA的标识可以是STA的MAC地址，也可以是其它唯一指示STA的标识。
下面描述本申请实施例中分配AID的方法流程中AP的处理，参见步骤701至步骤702，在步骤701至步骤702是以第一AP为例进行说明，第一AP属于管理设备管理的多个AP。
步骤701，第一AP接收管理设备发送的AID和STA的标识，该AID为管理设备为STA分配的AID。
步骤702，第一AP将STA的标识和AID对应存储。
在本实施例中，第一AP将STA的标识与目标AID对应存储，使得在第一AP接收到包括目标AID的消息时，确定该消息来自于该STA的标识指示的STA，并且使得第一AP向STA发送消息时携带AID即可。这样，AID一般是1个或2个字节，而MAC地址是6个字 节，携带AID相比携带MAC地址能够节约消息的字节开销。
结合图6和步骤701至步骤702，管理设备与第一AP交互的流程参见图7。
基于图7所示的流程，在多个AP共用一个BSSID的网络架构中，由管理设备统一为STA分配AID，使得为该网络架构下各个STA分配的AID不相同，进而在发送消息时可以携带AID用于标识STA。
下面对从管理设备和AP两侧的角度对分配AID的方法进行说明，参见图8所示的流程。
步骤801，STA发送认证请求，该认证请求包括STA的参数。
在本实施例中，STA先扫描无线网络，在扫描完成后，在屏幕中显示扫描到的无线网络，用户选择连接网络架构包括多个AP的无线网络(该网络架构对应一个BSSID)，STA生成认证请求，该认证请求包括STA的参数，该参数包括但不限于STA的能力等级和型号等。STA发送该认证请求。此处仅是一种可能的方式来触发STA发送认证请求，本申请实施例对此不进行限定。
步骤802，第一AP接收STA发送的认证请求。
在本实施例中，当前覆盖STA的AP均能接收到STA发送的认证请求，此处是假定第一AP接收到STA发送的认证请求。
步骤803，第一AP向管理设备发送认证上报消息，认证上报消息包括STA的参数。
步骤802至步骤803中仅示出第一AP接收到STA发送的认证请求，并向管理设备发送认证上报消息，此处有可能还有其它AP也接收到该STA发送的认证请求，其它AP也会向管理设备发送认证上报消息。
步骤804，管理设备接收多个AP中至少一个AP发送的认证上报消息，认证上报消息包括STA的参数。
其中，认证上报消息用于指示请求为STA执行认证操作。
在本实施例中，至少一个AP会向管理设备发送认证上报消息，管理设备会接收到至少一个AP发送的认证上报消息。
步骤805，管理设备从认证上报消息中，获取STA的参数。
在本实施例中，认证上报消息中某个字段专门用于存放STA的参数，管理设备可以从该字段中获取到STA的参数。
步骤806，管理设备获取至少一个AP的特征信息，每个AP的特征信息包括负载信息、受到的干扰信息和接收STA发送的信号的质量信息中的至少一种。
其中，至少一个AP为多个AP中接收到STA发送的认证请求的AP。
在一种实现中，AP在向管理设备发送认证上报消息时，认证上报消息中包括AP的特征信息，AP的特征信息包括AP的负载信息、受到的干扰信息和接收STA发送的信号的质量信息中至少一种，AP的负载信息指当前关联的STA的数目或者剩余可关联STA的数目，AP受到的干扰信息指AP受到其它AP的干扰值，接收STA发送的信号的质量信息指AP接收到STA发送的认证请求的信号强度等。管理设备可以从认证上报消息中获取到AP的特征信息。
在另一种实现中，认证上报消息中不包括特征信息，管理设备可以向AP发送特征信息的获取请求，AP向管理设备上报特征信息。
在另一种实现中，认证上报消息中不包括特征信息，对于质量信息，管理设备可以向AP发送质量信息的获取请求，AP向管理设备上报接收STA发送的信号的质量信息。对于负载信息，管理设备可以确定当前与AP通信的STA的数目，如管理设备第一次指定STA关联AP时，会记录AP与STA通信，在STA从当前通信的AP漫游至另一个AP的覆盖范围内时， 管理设备会更新与AP通信的STA。对于受到的干扰信息，管理设备获取最近一次AP上报的干扰信息，确定为受到的干扰信息。
步骤807，管理设备基于STA的参数，为STA分配目标AID，管理设备基于该至少一个AP的特征信息，确定该至少一个AP分别与STA的连接质量，将该至少一个AP中连接质量最高的AP确定为第一AP。
其中，至少一个AP为接收到STA发送的认证请求的AP。此处由于选取的第一AP是用于与STA进行通信，所以应该选取当前能接收到STA发送的认证请求的AP，使得STA能够与第一AP通信。
在本实施例中，管理设备为STA分配目标AID的过程参见步骤602的描述，此处不再赘述。
在至少一个AP的特征信息包括一种的情况下，对于任一AP，若该AP的特征信息包括的内容与连接质量负相关，则将特征信息包括的内容取倒数，确定为AP与STA的连接质量，若该AP的特征信息包括的内容与连接质量正相关，则将特征信息包括的内容，确定为AP与STA的连接质量。例如，特征信息包括负载信息，负载信息为与AP通信的STA的数目，将STA的数目的倒数确定为与STA的连接质量。
在至少一个AP的特征信息包括多种的情况下，对于任一AP，对特征信息的各种内容进行加权，获得加权值，将加权值确定为连接质量。此处，在加权时，与连接质量负相关的内容取倒数，使用取倒数的内容进行加权处理。具体的，特征信息中的各种内容的权重可以根据实际需要设置，本申请实施例不进行限定。
管理设备在确定出AP与STA的连接质量后，将连接质量最高的AP确定为第一AP。
需要说明的是，上述仅是基于特征信息确定连接质量的一种示例性的方式，本申请实施例不进行限定。
步骤808，管理设备向第一AP发送目标AID和STA的标识。并且向多个AP中除第一AP之外的其它AP发送目标AID和STA的标识。
在本实施例中，管理设备有多种方式通知目标AID，如下提供两种可行的方式。
方式一，管理设备向每个AP发送分配消息，分配消息包括AID分配字段，AID分配字段中包括STA的标识字段、AID字段和响应认证请求的指示字段，STA的标识可以是STA的MAC地址，AID字段中存放目标AID，参见图9所示的AID分配字段。对于发送给第一AP的AID分配字段中，响应认证请求的指示字段的内容用于指示第一AP向STA发送目标AID。对于发送给多个AP中除第一AP之外的其它AP的AID分配字段中，响应认证请求的指示字段的内容用于指示不向STA发送目标AID。例如，在发送给第一AP的AID分配字段中，响应认证请求的指示字段的内容为1，在发送给其它AP的AID分配字段中，响应认证请求的指示字段的内容为0。
方式二，管理设备向每个AP发送分配消息，分配消息包括AID分配字段，AID分配字段中包括AP的标识字段、STA的标识字段和AID字段，其中，AP的标识字段中存放第一AP的标识，第一AP的标识唯一指示第一AP，AID字段中存放目标AID，参见图10所示的AID分配字段。接收到该AID分配字段的AP判断自身的标识是否与AID分配字段中AP的标识相同，若相同，说明该AP为第一AP，若不相同，则说明该AP是多个AP中除第一AP之外的其它AP。
在方式一和方式二中，管理设备向多个AP中除第一AP之外的其它AP发送STA的标识和目标AID后，其它AP存储有目标AID和STA的标识，这样，STA从第一AP的覆盖范围 内漫游至其它AP的覆盖范围内，即使消息中携带目标AID而不携带STA的标识，其它AP也能识别到STA。
可选的，为了区分分配消息和后文提到的回收消息，AID分配字段包括消息标识符，消息标识符取不同的值，分别标识分配消息和回收消息。例如，消息标识符为1时，消息为分配消息，消息标识符为0时，消息为回收消息。
需要说明的是，在图9和图10所示的AID分配字段，可以是AID分配字段的部分内容。
示例性的，在不同的网络架构中，承载AID分配字段的消息格式有可能不相同。例如，多个AP与管理设备形成FTTR的网络架构，管理设备与多个AP之间分别通过光纤连接或者无线连接等。承载AID分配字段的消息可以称为是分配消息，参见图11所示的分配消息，分配消息包括AID分配字段、目的地址字段、源地址字段、消息类型字段、载荷长度字段和载荷字段，载荷字段也可以称为是净荷字段。对于发送给任一AP的分配消息，目的地址为该AP的标识，AP的标识唯一指示该AP，不同AP具有不同的标识，此处AP的标识可以是任意可以唯一标识AP的内容，如索引号等，例如，发送给第一AP的分配消息的目的地址为第一AP的索引号。源地址为管理设备的标识，管理设备的标识可以是管理设备的MAC地址，或者是唯一标识管理设备的索引标识。值得注意的是，在管理设备为中心AP时，由于中心AP与其它AP的MAC地址相同，所以管理设备的标识不是MAC地址。消息类型字段标识分配消息是控制消息，而不是数据消息。
可选的，分配消息还包括保留(reserved)字段。
多个AP与管理设备形成以太网架构，管理设备与多个AP分别通过光纤或电缆连接。承载AID分配字段的分配消息格式是以太网帧，参见图12所示的以太网帧，AID分配字段位于以太网帧的载荷字段中。在图12所示的以太网帧中，若管理设备不是网络架构下的中心AP，则源地址为管理设备的MAC地址，目的地址为接收以太网帧的AP的虚拟MAC地址。若管理设备是网络架构下的中心AP，则源地址为管理设备的虚拟MAC地址，目的地址为接收以太网帧的AP的虚拟MAC地址。此处，在一个BSSID标识的网络架构内，由于每个AP的MAC地址相同，所以为了区分不同的AP，为每个AP分配一个虚拟MAC地址，用于区分不同的AP。例如，在每个AP上线后，管理设备为每个AP分配不同的虚拟MAC地址。另外，每个AP的虚拟MAC地址对STA不可见，在AP与STA通信时，携带的是AP的MAC地址，而非虚拟MAC地址。
另外，以太网帧还包括类型(type)字段、长度(length)字段和帧校验序列(frame check sequence，FCS)字段等。
多个AP与管理设备形成PON的架构，管理设备与多个AP之间通过光分配网络(optical distribution network，ODN)连接。承载AID分配字段的分配消息格式是OMCI消息的格式，参见13所示的OMCI消息，AID分配字段位于OMCI消息的消息内容(Message Contents)字段中。在图13所示的OMCI消息中，OMCI消息还包括无源光接入系统封装格式(Gigabit-Capable PON encapsulation mode，GEM)头(Header)字段、事务相关标识(Transaction Correlation Identifier)字段、消息类型(Message Type)字段、设备标识(Device Identifier)字段、消息标识(Message Identifier)字段和OMCI末尾(Trailer)字段等。
其中，GEM Header字段包括GEM载荷长度、GEM端口标识、载荷类型标识(payload type indicator，PTI)和信头差错校验(header error check，HEC)等，不同GEM端口标识用于标识不同AP，AP接收到OMCI消息后，可以将携带自身对应的GEM端口标识的OMCI消息，确定为发送给自己的OMCI消息。
Transaction Correlation Identifier字段的值在一组对应请求和响应的消息要一致。Message Type字段用于标识消息的具体类型，例如，Message Type字段的内容为0x20。Device Identifier字段用于标识AP的类型。Message Identifier字段用于标识消息的总类型，Message Type属于Message Identifier标识的总类型中的一种。OMCI Trailer字段用于消息校验。
步骤809，第一AP接收管理设备发送的目标AID和STA的标识。
步骤810，除第一AP之外的其它AP接收管理设备发送的目标AID和STA的标识。
在本实施例中，除第一AP之外的其它AP将目标AID和STA的标识对应存储，在图8中仅示出第二AP接收目标AID和STA的标识。
步骤811，第一AP将STA的标识和目标AID对应存储。
在本实施例中，第一AP将STA的标识与目标AID存储为对应关系，并且在该对应关系中记录STA的能力信息等。
步骤812，在第一AP为管理设备指定的与STA关联的AP的情况下，第一AP向STA发送认证响应消息。
在本实施例中，第一AP接收到目标AID和STA的标识时，由于第一AP是管理设备指定的响应STA的设备，所以第一AP向STA发送认证响应消息。
步骤813，STA接收认证响应消息，发送关联请求。
在本实施例中，STA接收第一AP发送的认证响应消息后，生成关联请求，关联请求包括但不限于STA支持的速率、信道、服务质量(quality of service，QoS)的能力，以及选择的接入认证和加密算法等，然后STA发送关联请求。此处由于相同BSSID的AP的MAC地址相同，所以对于STA来说，只是向该MAC地址的AP发送关联请求，覆盖STA的AP均可能接收到关联请求。
步骤814，第一AP接收STA发送的关联请求。
步骤815，在第一AP为管理设备指定的与STA关联的AP的情况下，第一AP向STA发送关联响应消息，关联响应消息包括目标AID。
在本实施例中，第一AP是管理设备指定的与STA关联的设备，第一AP向STA发送关联响应消息，在该关联响应消息中包括目标AID。
另外，对于除第一AP之外的其它AP也有可能接收到关联请求，但是由于其它AP并不是指定与STA关联的设备，所以不会向该STA回复关联响应消息。
需要说明的是，在多个AP与管理设备形成FTTR的网络架构的情况下，在步骤803中，认证上报消息的格式可以与图11所示的消息的格式相同。在多个AP与管理设备形成以太网架构的情况下，在步骤803中，认证上报消息的格式可以与图12所示的以太网帧的格式相同。在多个AP与管理设备形成PON的架构的情况下，在步骤803中，认证上报消息的格式可以与图13所示的OMCI消息的格式相同。
还需要说明是，在图8所示的流程中，管理设备向第二AP发送目标AID和STA的标识，在步骤808中，也可以是在第一AP与STA关联完成后，第一AP向第二AP发送目标AID和STA的标识。另外，管理设备或第一AP向第二AP发送目标AID和STA的标识时，还可以发送第一AP与STA关联时协商的内容，如STA支持的速率、信道、QoS的能力，以及选择的接入认证和加密算法等，这样，STA漫游至第二AP的覆盖范围内后，第二AP可以直接与STA通信，为STA提供报文转发的功能。
本申请实施例中，在STA移动后，还可以调整为STA的报文提供转发处理的AP，处理过程如下：
经过图8所示的流程STA与第一AP关联之后，第一AP负责对STA的报文(STA的报文包括发往STA的报文以及接收自STA的报文)进行转发，认为STA当前处于第一AP的覆盖范围，STA有可能会发生移动，使得从第一AP的覆盖范围内移动至多个AP中第二AP的覆盖范围内。例如，用户所在的公司包括多个办公区域，用户从一个办公区域移动至另一个办公区域，用户的STA也可能从第一AP的覆盖范围内移动至第二AP的覆盖范围内。参见图14，管理设备可以向第二AP发送通知消息，为了和后文中的通知消息区分，该通知消息称为是第一通知消息，该第一通知消息指示第二AP与STA进行连接。第二AP接收到该第一通知消息后，后续再接收到该STA的报文后，负责进行转发处理。此处第二AP已经存储有STA的标识和目标AID，所以第二AP能够基于AID区分STA。
可选的，管理设备可以向第一AP发送第二通知消息，第二通知消息指示第一AP不再转发STA的报文。这样，在第一AP与第二AP的覆盖范围有重叠时，也是同一时刻仅有一个AP负责转发STA的报文。
示例性的，第一通知消息和第二通知消息还可以携带相同的时间指示标识，该时间指示标识指示第一AP在该时间之后不再转发STA的报文，并指示第二AP在该时间之后开始转发STA的报文。
示例性的，管理设备确定STA进入第二AP的覆盖范围内的处理为：
每次AP接收到STA发送的报文后，记录接收报文的信号强度，向管理设备发送该信号强度和STA的标识，或者向管理设备发送该信号强度和目标AID。管理设备接收到该信号强度和目标AID后，第一AP接收STA发送的报文的信号强度为第一强度，第二AP接收STA发送的报文的信号强度为第二强度，若第一强度低于第二强度，则确定STA从第一AP的覆盖范围内漫游至第二AP的覆盖范围内。此处AP也可以周期性获取接收STA发送的报文的信号强度，向管理设备发送。
可选的，若在一段时间内第一强度持续低于第二强度，则确定STA从第一AP的覆盖范围内漫游至第二AP的覆盖范围内。
需要说明的是，第一通知消息中可以携带STA的标识以及指示转发报文的标识，第二通知消息中可以携带STA的标识以及指示停止转发报文的标识。
还需要说明的是，STA发出报文时，覆盖该STA的AP均有可能接收到该报文，但是由于某一时刻管理设备仅指定一个AP与STA进行连接，所以不会存在多个AP同时处理STA的报文。另外，由于多个AP的MAC地址相同，所以从STA的角度看，STA认为始终接入一个无线网络。
本申请实施例中，为了使得更多的STA接入无线网络，在STA从无线网络离线后，回收为该STA分配的AID，被回收的AID可以分配给其它待接入无线网络的AP。回收处理流程参见图15的步骤1501至步骤1505。
步骤1501，管理设备检测到STA离线。
在本实施例中，管理设备检测STA离线有多种方式，此处提供两种可行的方式：
方式一，每次AP接收到STA发送的报文后，记录接收报文的信号强度，向管理设备发送该信号强度和STA的标识，或者向管理设备发送该信号强度和目标AID。管理设备在第一时长内未接收到AP发送接收STA的报文的信号强度，则确定STA离线。第一时长可以根据实际需要设置。
方式二，与STA关联的AP检测到STA离线，该AP向管理设备发送STA离线的消息，管理设备接收到该消息后，确定STA离线。示例性的，该AP检测到STA离线的方式为：AP 主动确定STA离线，例如，在STA已经关联至该AP后，管理人员在该AP中输入接入黑名单，若STA位于该黑名单中，则该AP确定STA离线。再例如，与STA关联的AP会周期性向AP发送管理帧，STA在目标数目个周期或者第二时长内未响应，确定STA离线。目标数目和第二时长可以根据实际需要设置。
或者，STA在某些情况下，向AP发送离线消息，该AP确定STA离线。例如，STA切换无线网络，STA向该AP发送离线消息，该AP确定STA离线。
方式一和方式二仅是两种可选的方式，本申请实施例对此不进行限定。
步骤1502，管理设备向第一AP分别发送回收消息，回收消息用于指示回收目标AID。
在本实施例中，管理设备确定STA离线后，生成回收消息，该回收消息包括STA的标识或者目标AID。管理设备向多个分配发送回收消息。
示例性的，回收消息包括AID回收字段，AID回收字段中包括AID字段，或者AID回收字段包括AID字段和STA的标识字段。或者，AID回收字段包括AID字段、STA的标识字段和消息标识符字段，AID字段用于存放目标AID，消息标识符用于指示消息是回收消息还是分配消息，在消息标识符取值为1时，消息是分配消息，在消息标识符取值为0时，消息是回收消息，例如，参见图16所示的AID回收字段，以及AID分配字段。
示例性的，在不同的网络架构中，承载AID回收字段的回收消息格式有可能不相同。例如，多个AP与管理设备形成FTTR的网络架构，管理设备与多个AP之间分别通过光纤连接或者无线连接等。参见图17所示的回收消息，回收消息包括AID回收字段、目的地址字段、源地址字段、消息类型字段、载荷长度字段和载荷字段。对于发送给任一AP的回收消息，目的地址为该AP的标识，AP的标识唯一指示该AP，不同AP具有不同的标识。源地址为管理设备的标识，管理设备的标识可以是管理设备的MAC地址，或者是唯一标识管理设备的索引标识。消息类型字段标识回收消息是控制消息。
可选的，回收消息还包括保留字段。
再例如，多个AP与管理设备形成以太网架构，管理设备与多个AP分别通过光纤或电缆连接。承载AID回收字段的回收消息格式是以太网帧，AID回收字段位于以太网帧的载荷字段中。源地址和目的地址参见图12所示的以太网帧的源地址和目的地址。
再例如，多个AP与管理设备形成PON的架构，管理设备与多个AP之间通过ODN连接。承载AID回收字段的回收消息格式是OMCI消息的格式，AID回收字段位于OMCI消息的消息内容字段中。此处，OMCI消息的结构参见图13。
步骤1503，多个AP分别接收管理设备发送的回收消息。
步骤1504，多个AP分别回收目标AID。
在本实施例中，多个AP中的每个AP接收到回收消息后，将目标AID删除。例如，多个AP中第一AP将目标AID和STA的标识的对应关系删除。
步骤1505，多个AP分别向管理设备发送回收完成消息。
在本实施例中，在AP将目标AID删除后，STA的标识与目标AID不存在对应关系。管理设备接收到多个AP中每个AP发送的回收完成消息后，管理设备可以将目标AID分配给待接入的另一STA。这样，在STA离线后，目标AID还可以提供给其它STA使用，提高AID的利用率。
可选的，在目标AID被回收后，管理设备设置目标AID的标记位置为1，说明目标AID可以分配给其它STA。
需要说明的是，在图15中仅示出了管理设备向第一AP发送回收消息，管理设备向其它 AP发送回收消息的处理参见图15。
在另一种实现中，管理设备仅向第一AP发送AID和STA的标识，管理设备可以仅向第一AP发送回收消息，使得第一AP将AID删除。
在另一种实现中，管理设备向自身管理的多个AP均发送AID和STA的标识，管理设备可以向第一AP发送回收消息，使得第一AP将AID删除，并且使得第一AP向多个AP中除第一AP之外的其它AP发送回收消息，使得其它AP将AID删除。
本申请实施例中，还提供了管理设备检测AP的状态的过程，处理为：管理设备与各AP之间建立心跳连接，管理设备周期性向AP发送心跳消息，若连续目标数目个周期内，管理设备未接收到某个AP发送的心跳答复消息，则确定该AP故障，可以向管理人员的设备发送提示消息，使得管理人员及时对该AP进行故障排查。此处目标数目可以根据实际需要设置。
本申请实施例中，在一个BSSID标识的网络架构中，由管理设备统一分配AID，使得接入该网络架构中不同STA对应不同的AID，使得多个AP与STA之间携带AID的消息不会发生混乱。而且由于一个AID唯一对应一个STA，所以可以使用AID代替MAC地址标识STA，节约字节开销。例如，MAC地址为6字节，而使用AID可以降低至1字节或者2字节。
