If the non-AP station 106 does not support the solution of the embodiment of the present invention, the first wireless station and the second wireless station may be two wireless stations among all wireless stations except the non-AP station 106 in FIG. 1 .
网格资料用在一个单独的网格基本服务集(英文：basic service set，缩写：BSS)中。网格资料是识别网格基本服务集(英文：mesh basic service set，缩写：MBSS)的属性的参数的值的集合。The grid data is used in a separate grid basic service set (English: basic service set, abbreviation: BSS). The mesh data is a set of values of parameters identifying attributes of a mesh basic service set (English: mesh basic service set, abbreviation: MBSS).
上述网格对等帧为以下帧中的至少一个：网格对等打开(英文：mesh peeringopen)帧和网格对等确认(英文：mesh peering confirm)帧。如果mesh peering open帧和mesh peering confirm帧都携带第二无线站点的身份的信息以及该第二无线站点发送网格对等帧的端口的标识，通常在同一个mesh BSS中的第一无线站点和第二无线站点间，第二无线站点发送的mesh peering open帧和mesh peering confirm帧携带的网格对等帧的端口的标识是相同的。如果上述两者携带的网格对等帧的端口的标识不同，则第一无线站点按照预设的规则处理，例如以mesh peering confirm帧携带的为准，或者终止流程并报错。The above mesh peering frame is at least one of the following frames: a mesh peering open (English: mesh peering open) frame and a mesh peering confirm (English: mesh peering confirm) frame. If both the mesh peering open frame and the mesh peering confirm frame carry the identity information of the second wireless station and the identifier of the port through which the second wireless station sends the mesh peering frame, usually the first wireless station in the same mesh BSS and the Between the second wireless stations, the mesh peering open frame sent by the second wireless station and the mesh peering confirm frame carried by the mesh peering confirm frame have the same port identifier. If the port identifiers of the mesh peering frames carried by the above two are different, the first wireless station processes according to preset rules, for example, the mesh peering confirm frame carries, or terminates the process and reports an error.
无线站点的身份的信息可以为以下一个或多个的组合：无线站点的介质访问控制(英文：media access control，缩写：MAC)地址，无线站点的设备名称和无线站点的管理网际网络(英文：Internet，缩写：IP)地址。其中，设备名称是网络中设备的唯一名称，可以被手动的或者自动的分配给各个无线站点。如果无线站点的身份的信息为无线站点的管理IP地址或无线站点的管理IP地址与其他信息的组合，则管理员可以根据构建的无线局域网网格网络的拓扑中无线站点的身份的信息里的管理IP地址管理对应的无线站点。The identity information of the wireless station may be a combination of one or more of the following: the media access control (English: media access control, abbreviation: MAC) address of the wireless station, the device name of the wireless station and the management Internet of the wireless station (English: Internet, abbreviation: IP) address. The device name is the unique name of the device in the network, which can be manually or automatically assigned to each wireless station. If the identity information of the wireless site is the management IP address of the wireless site or the combination of the management IP address of the wireless site and other information, the administrator can use the information in the identity information of the wireless site in the topology of the constructed wireless local area network mesh network according to the The management IP address manages the corresponding wireless site.
在无线局域网网格网络中，并没有通常的物理端口，本发明中的术语“端口”不同于通信技术中通常的物理端口，也不同于一般的虚拟端口。本发明中的端口的标识是指能够表明发送网格对等帧的网格对等管理有限状态机(英文：mesh peering managementfinite state machine，缩写：MPM FSM)的标识。MPM FSM控制网格STA发送和接收网格对等帧。举例来说，如果第二无线站点中所有的MPM FSM都有不同的标识，则第二无线站点发送网格对等帧的端口的标识可以为发送该网格对等帧的MPM FSM的标识，或者为网格ID与MPMFSM的标识的组合；如果第二无线站点中在同一个网格中的所有的MPMFSM都有不同的标识，而不同网格中的MPM FSM可能有相同的标识，则第二无线站点发送网格对等帧的端口的标识可以为网格ID与MPM FSM的标识的组合。上述网格ID与MPM FSM的标识的组合可以是网格ID与MPM FSM的简单叠加，也可以根据网格ID与MPM FSM的标识计算得到第二无线站点发送网格对等帧的端口的标识，该标识可以唯一标识一个无线站点中的MPM FSM。In the wireless local area network mesh network, there is no common physical port, and the term "port" in the present invention is different from the common physical port in the communication technology, and also different from the common virtual port. The identifier of the port in the present invention refers to the identifier of the mesh peering management finite state machine (English: mesh peering management finite state machine, abbreviation: MPM FSM) that can send the mesh peering frame. The MPM FSM controls mesh STAs to send and receive mesh peer frames. For example, if all MPM FSMs in the second wireless station have different identities, the identity of the port through which the second wireless station sends the mesh peer-to-peer frame may be the identity of the MPM FSM that sends the mesh peer-to-peer frame, Or it is the combination of the grid ID and the identity of the MPMFSM; if all the MPMFSMs in the same grid in the second wireless site have different identities, and the MPM FSMs in different grids may have the same identity, then the first The identifier of the port through which the second wireless station sends the mesh peer-to-peer frame may be a combination of the mesh ID and the identifier of the MPM FSM. The combination of the above-mentioned grid ID and the identification of the MPM FSM can be a simple superposition of the grid ID and the MPM FSM, or the identification of the port through which the second wireless station sends the grid peer-to-peer frame can be calculated according to the grid ID and the identification of the MPM FSM. , which can uniquely identify the MPM FSM in a wireless site.

The first wireless station saves a first correspondence, where the first correspondence includes the grid data and the identity information of the second wireless station, and the second wireless station sends the grid pair The corresponding relationship between the identifier of the port of the peer-to-peer frame and the identifier of the port of the first wireless station to receive the peer-to-peer frame of the mesh.
第一无线站点获取网格对等帧中的网格资料，第二无线站点的身份的信息以及该第二无线站点发送网格对等帧的端口的标识，建立它们和该第一无线站点接收该网格对等帧的端口的标识间的对应关系，并将该对应关系作为第一对应关系保存在第一无线站点中。The first wireless station acquires the grid data in the grid peer-to-peer frame, the information of the identity of the second wireless station and the identification of the port through which the second wireless station sends the grid peer-to-peer frame, establishes them and receives the first wireless station The correspondence between the identifiers of the ports of the mesh peer-to-peer frame, and the correspondence is stored in the first wireless station as the first correspondence.
在无线站点的身份的信息是无线站点的MAC地址和其它信息(例如无线站点的设备名称和无线站点的管理IP地址中的一个或多个)的组合的情况下，可选的，第一无线站点接收第二无线站点周期性发送的信标(英文：beacon)帧，beacon帧中包括网格资料和第二无线站点的身份的信息。第一无线站点根据beacon帧中的网格资料和第二无线站点的身份的信息中的MAC地址更新上述第一对应关系中的第二无线站点的身份的信息中的其它信息。某些场景中，无线站点的身份的信息可能变化，例如无线站点的设备名称被重新命名，但无线站点的身份的信息中的无线站点的MAC地址不会变化，第一无线站点可以根据beacon帧中第二无线站点的身份的信息中的第二无线站点的MAC地址找到上述第一对应关系中的第二无线站点的身份的信息，并更新该第二无线站点的身份的信息。In the case where the information of the identity of the wireless station is a combination of the MAC address of the wireless station and other information (eg, one or more of the device name of the wireless station and the management IP address of the wireless station), optionally, the first wireless station The station receives a beacon (English: beacon) frame periodically sent by the second wireless station, where the beacon frame includes mesh data and information about the identity of the second wireless station. The first wireless station updates other information in the identity information of the second wireless station in the first correspondence according to the mesh data in the beacon frame and the MAC address in the identity information of the second wireless station.

上述网格对等帧为以下帧中的至少一个：网格对等打开帧和网格对等确认帧。如果mesh peering open帧和mesh peering confirm帧都携带第二无线站点的身份的信息以及该第二无线站点发送网格对等帧的端口的标识，通常在同一个mesh BSS中的该无线站点和第二无线站点间，第二无线站点发送的mesh peering open帧和mesh peering confirm帧携带的网格对等帧的端口的标识是相同的。如果上述两者携带的网格对等帧的端口的标识不同，则该无线站点按照预设的规则处理，例如以mesh peering confirm帧携带的为准，或者终止流程并报错。The above grid peer frame is at least one of the following frames: grid peer open frame and grid peer confirmation frame.
