一种角色自选举的方法、装置及计算机可读存储介质
相关申请的交叉引用
本申请基于申请号为201910901553.7、申请日为2019年09月23日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明实施例涉及但不限于多接入点AP网络，更具体地涉及一种角色自选举的方法、装置及计算机可读存储介质。
背景技术
随着家庭无线网络的发展，使用多台AP(Multi Access Point，多接入点)扩展无线覆盖网络会越来越多。
在家庭网关多AP网络组网中，设备有两种角色，一种是作为控制端的控制者(controller)，另一种是作为客户端的代理(agent)。如图1所示，controller控制者：是整个组网的逻辑控制单元，用于控制多AP组网中的前端网络、后端链路；例如收集组网中的AP、STA(Station，站点)的能力数据，控制漫游策略，将无线的配置下发同步给代理agent等。一个网络中有且只有一个控制者controller。因为控制者controller是网络控制主体，所以一般希望控制者controller位于网络。代理agent：是多AP组网的逻辑实体，主要接受多AP指令，并完成相应的操作，包括接受控制者controller下发的配置同步指令等。图1中只是示例有两个分别作为AP2和AP3的代理(agent)和两个STA站点，实际组网中，一个网络中可以有一个或多个代理agent。
目前，多AP网络中的AP由用户手动配置角色，例如用户可以通过WebUI(网络产品界面，Website User Interface)或者手机APP(Application，应用程序)来设定角色为控制者controller或代理agent。如此，导致多AP组网效率较低。
发明内容
有鉴于此，本发明实施例提供了一种角色自选举的方法，应用于多接入点AP网络，包括：所述多AP网络中的AP启动后，发送接入点自动配置搜索报文；当所述AP在预设时间内收到所述接入点自动配置搜索报文的响应报文时，将自己的角色设置为代理agent。
本发明实施例还提供了一种角色自选举的装置，应用于多接入点AP网络中的AP，包括：发送单元，用于所述AP启动后，发送接入点自动配置搜索报文；设置单元，用于当 在预设时间内收到所述接入点自动配置搜索报文的响应报文时，将所述AP的角色设置为代理agent。
本发明实施例还提供了一种角色自选举的装置，应用于多接入点AP网络中的AP，包括存储器、处理器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现上述角色自选举的方法。

图2为本发明一实施例提供的一种角色自选举的方法的流程示意图。如图2所示，该方法，应用于多接入点AP网络，包括：
步骤201，所述多AP网络中的AP启动后，发送接入点自动配置搜索报文；
步骤202，当所述AP在预设时间内收到所述接入点自动配置搜索报文的响应报文时，将自己的角色设置为代理agent；
其中，该方法还包括：
当所述AP在预设时间内没有收到所述接入点自动配置搜索报文的响应报文时，将自己的角色设置为控制者controller。
其中，该方法还包括：
当所述AP在预设时间内没有收到所述接入点自动配置搜索报文的响应报文时，重复发送所述接入点自动配置搜索报文；
以此类推，最多重复发送预设次数，直至收到所述接入点自动配置搜索报文的响应报文时，将自己的角色设置为代理agent。
其中，该方法还包括：
直至重复预设次数发送所述接入点自动配置搜索报，没有收到所述接入点自动配置搜索报文的响应报文时，确定与自己的广域网(WAN)接口直连的设备是否是1905设备；
如果所述与自己的WAN接口直连的设备是1905设备，则将自己的角色设置为代理agent。
其中，该方法还包括：
如果所述与自己的WAN接口直连的设备不是1905设备，则将自己的角色设置为控制者controller。
其中，所述确定与自己的WAN接口直连的设备是否是1905设备，包括：
确定自己的WAN接口是否收到拓扑发现报文；
当自己的WAN接口收到拓扑发现报文时，确定所述与自己的WAN接口直连的设备是1905设备；

其中，当所述AP将自己的角色设置为代理agent后，该方法还包括：
所述AP与所述多AP网络中的控制者controller设备进行无线保真技术简单配置WSC交互，完成无线配置同步。
图3为本发明另一实施例提供的一种角色自选举的方法的流程示意图。
本实施例可以应用于图4所示的多AP网络组网。如图4所示，AP1接入到PON HGW(Passive Optical Network Home Gateway，无源光纤网络家庭网关)下，AP2和AP3设备通过有线或者无线接入到AP1中。
本实施例可以应用于图5所示的多AP网络组网。如图5所示，AP1直接接入外部WAN(Wide Area Network，广域网)，AP2、AP3设备通过有线或者无线接入到AP1中。
本实施例中，以AP1作为执行主体为例，详细说明本实施例技术方案。
如图3所示，该方法，应用于多接入点AP网络，包括：
步骤301，AP1启动后，发送接入点自动配置搜索报文；
其中，该接入点自动配置搜索报文可以为现有1905协议中的AP-autoconfig search报文，该AP-autoconfig search报文是一种二层组播报文。
具体而言，当多AP网络中，已经设置有控制者controller设备时，控制者controller收到AP1发送的AP-autoconfig search报文后，会向AP1回复一个AP-autoconfig search response报文，该AP-autoconfig search response报文是一种二层单播报文。当多AP网络中，还没有控制者controller设备时，AP1发送的AP-autoconfig search报文后，并不会收到AP-autoconfig search response报文。另外，由于网络传输存在延时，为了提高准确性，可以提前设定一个预设时间。如此，AP1可以根据在预设时间内是否收到AP-autoconfig search response报文来判断网络中是否已经有控制者controller设备。
当所述AP1在预设时间内收到所述接入点自动配置搜索报文的响应报文时，执行步骤302，当所述AP1在预设时间内没有收到所述接入点自动配置搜索报文的响应报文时，执行步骤303：
步骤302，将自己的角色设置为代理agent；
步骤303，将自己的角色设置为控制者controller。
图6为本发明另一实施例提供的一种角色自选举的方法的流程示意图。
本实施例可以应用于图4所示的多AP网络组网。如图4所示，AP1接入到PON HGW(Passive Optical Network Home Gateway，无源光纤网络家庭网关)下，AP2和AP3设备通过有线或者无线接入到AP1中。
本实施例可以应用于图5所示的多AP网络组网。如图5所示，AP1直接接入外部WAN(Wide Area Network，广域网)，AP2、AP3设备通过有线或者无线接入到AP1中。
本实施例中，以AP2作为执行主体为例，详细说明本实施例技术方案。其中，AP2的WAN接口(Wide Area Network port，广域网接口)和设备AP1的LAN接口(Local Area Network port，局域网接口)连接。
如图6所示，该方法，应用于多接入点AP网络，包括：
步骤601，AP2启动后，发送接入点自动配置搜索报文；
其中，该接入点自动配置搜索报文可以为现有1905协议中的AP-autoconfig search报 文，该AP-autoconfig search报文是一种二层组播报文。
当多AP网络中，已经设置有控制者controller设备时，控制者controller收到AP2发送的AP-autoconfig search报文后，会向AP2回复一个AP-autoconfig search response报文，该AP-autoconfig search response报文是一种二层单播报文。当多AP网络中，还没有控制者controller设备时，AP2发送的AP-autoconfig search报文后，并不会收到AP-autoconfig search response报文。另外，由于网络传输存在延时，为了提高准确性，可以提前设定一个预设时间。如此，AP2可以根据是否收到AP-autoconfig search response报文来判断网络中是否已经有控制者controller设备。
并且为了避免误差，可以提前设定一个预设时间，当超过预设时间，没有收到响应时，可以根据预设的重复次数重复发送AP-autoconfig search报文。例如，如果超时60s(时间可以自定义)，重复3次(次数可以自定义)发送AP-autoconfig search报文。
当所述AP2在预设时间内收到所述接入点自动配置搜索报文的响应报文时，执行步骤602，当所述AP2在预设时间内没有收到所述接入点自动配置搜索报文的响应报文时，执行步骤603：
步骤602，将自己的角色设置为代理agent；
具体而言，设备AP2的WAN接口up，发送AP-autoconfig search报文。若收到AP_AUTOCONFIGURATION_RESPONSE报文，设置自己角色为代理agent，结束流程。若没有收到AP_AUTOCONFIGURATION_RESPONSE报文，则进入步骤603，
步骤603，重复发送所述接入点自动配置搜索报文；以此类推，最多重复发送预设次数，直至收到所述接入点自动配置搜索报文的响应报文时，执行步骤604；没有收到所述接入点自动配置搜索报文的响应报文时，执行步骤605：
例如，重复发送所述接入点自动配置搜索报文后收到响应，则将自己的角色设置为代理agent，否则再次重复发送，收到响应则将自己的角色设置为代理agent，否则再次重复发送，以此类推，如果重复3次发送后都没有收到响应，则查看AP2的WAN接口下是否有1905设备，有则设置AP2角色为代理agent，结束流程，否则设置AP2角色为控制者controller。
步骤604，将自己的角色设置为代理agent；
步骤605，确定与自己的WAN接口直连的设备是否是1905设备；
其中，所述确定与自己的WAN接口直连的设备是否是1905设备，包括：
确定自己的WAN接口是否收到拓扑发现报文；
当自己的WAN接口收到拓扑发现报文时，确定所述与自己的WAN接口直连的设备 是1905设备；
当自己的WAN接口没有收到拓扑发现报文时，确定所述与自己的WAN接口直连的设备不是1905设备。
其中，如果AP2收到AP-autoconfig search response报文，说明在此网络中已经有控制者controller设备，将自己设置为代理agent，例如如果超时60s(时间可以自定义)，重复3次(次数可以自定义)，可以认为网络中还没有控制者controller设备，这个时候查看和自己的WAN接口直连的设备是否是1905设备。
如果是1905设备，则说明远离网络出口，执行步骤606，如果不是1905设备，则说明靠近网络出口，执行步骤607：
步骤606，将自己的角色设置为代理agent；
步骤607，将自己的角色设置为控制者controller。
具体而言，可以根据IEEE 1905.1-2013协议的discovery报文来确定直连设备是否是1905设备。例如设备AP2的WAN接口UP能够收到TOPOLOGY_DISCOVERY报文，则将自己设置为代理agent。
其中，可以根据IEEE 1905.1topology discovery protocol确定是否是1905设备。例如，Wan接口up后如果收到Topology discovery、Topology query、Topology notification等报文，则将自己设置为代理agent。
本发明的另一实施例中，当AP角色自选举为代理agent后，在上述实施例的基础上，该方法还包括：代理agent设备可以通过AP-autoconfig search response报文或者拓扑发现报文知道控制者controller设备的mac地址，与控制者controller设备进行WSC(Wi-Fi Simple Configuration，无线保真技术简单配置)交互，完成无线配置同步。
上述实施例提供的技术方案，家庭网关多AP组网(P1905协议、Multi-AP(Multi Access Point,多接入点)协议)中的AP设备，利用P1905协议的AP-autoconfiguration(接入点自动配置)部分进行角色自选举，减少了人工干预，提升了放装能力。
图7为本发明一实施例提供的一种角色自选举的装置的结构示意图。如图7所示，应用于多接入点AP网络中的AP，包括：
发送单元71，用于所述AP启动后，发送接入点自动配置搜索报文；
设置单元72，用于当在预设时间内收到所述接入点自动配置搜索报文的响应报文时，将所述AP的角色设置为代理agent。

其中，所述设置单元72，还用于直至重复预设次数发送所述接入点自动配置搜索报文，没有收到所述接入点自动配置搜索报文的响应报文时，确定与自己的WAN接口直连的设备是否是1905设备；
如果所述与自己的WAN接口直连的设备是1905设备，则将自己的角色设置为代理agent。
其中，所述设置单元72，还用于如果所述与自己的WAN接口直连的设备不是1905设备，则将自己的角色设置为控制者controller。
其中，所述确定与自己的WAN接口直连的设备是否是1905设备，包括：

其中，该装置还包括：
