TECHNICAL FIELD

[0001] The present application relates to the field of wireless communication, and more particularly, to an EasyMesh networking network switching method, a network protection system, a controller and a sub-controller access method. BACKGROUND

[0002] With the rapid development of network technology, people's requirements for the stability of wireless networks are getting higher and higher. EasyMesh can expand the coverage of wireless networks, improve the stability and performance of wireless networks, and is easy to operate. According to the general standard of EasyMesh, different brands of devices are allowed to form a Mesh network, so it is widely used in various places. The failure of the controller access point in the EasyMesh network will cause the connection of the entire network to be interrupted. After the failure of the controller access point, the user needs to re-network. At present, some users are not familiar with the operation, which often leads to network failure, resulting in poor user experience. In addition, the network in hotels, apartments, villas and other areas is more complex, and the placement of the equipment is fixed, which increases the workload of the user to re-network. In addition, hotels, apartments, villas and other areas have high requirements for network recovery speed. SUMMARY

[0008] S2: The sub-controller access point receives the parameter information of the controller access point, and disconnects the information synchronization channel;

[0009] S3: The sub-controller access point switches to the controller access point, and the controller access point switches to the sub-controller access point, and re-establishes the information synchronization channel between the controller access point and the sub-controller access point.

[0010] Further, in step S1, the parameter information that has changed most recently is synchronized to the sub-controller access point through the information synchronization channel, including: when the parameter information of the controller access point changes, the parameter information is synchronized to the sub-controller access point through the information synchronization channel, the sub-controller access point sends a parameter synchronization success message to the controller access point, if the sub-controller access point does not send the parameter synchronization success message or the controller access point does not receive the parameter synchronization success message, the parameter synchronization success message is re-sent, and if the controller access point receives the parameter synchronization success message, the step S2 is jumped to.

[0011] Further, in step S3, after the information synchronization channel between the controller access point and the sub-controller access point is re-established, the Fronthaul-AP and Backhaul-AP interfaces of the controller access point are started, and the terminal device and the Agent-AP access the controller access point.

[0012] Further, in step S3, the sub-controller access point switches to the controller access point, including: after receiving the disconnection of the Sub-STA wireless VLAN sub-interface of the controller access point or not receiving the message from the Sub-STA wireless VLAN sub-interface within a preset time, the sub-controller access point switches to the controller access point.

[0017] A controller access method is applied to the network switching method, including the following steps:

[0018] S01: judging whether the data service of the controller access point is normal, if the data service is normal, the step S2 is jumped to, and if the data service is not normal, the step S03 is jumped to.

[0035] It is understandable for those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0036] The technical solutions of the application will be further described below in combination with the drawings and embodiments.

[0037] Embodiment 1

[0038] An EasyMesh networking network switching method, as shown in Figure 1 , includes the following steps:

[0039] S1: When the data service of the controller access point of the EasyMesh networking is not normal, the parameter information of the last change is synchronized to the sub-controller access point through the information synchronization channel;

[0040] S2: The sub-controller access point receives the parameter information of the controller access point, and disconnects the information synchronization channel;

[0041] S3: The sub-controller access point switches to the controller access point, and the controller access point switches to the sub-controller access point, and the information synchronization channel of the controller access point and the sub-controller access point is re-established.

[0042] In the specific implementation process, as shown in Figure 3 , the parameter information of the last change away from the data service exception is synchronized to the sub-controller access point through the information synchronization channel. After receiving the parameter information, the sub-controller access point disconnects the synchronization channel and switches to the main controller access point, takes over the data service, and the original main controller access point switches to the sub-controller access point. The new main controller access point will re-establish the information synchronization channel with the sub-controller access point to ensure the synchronization of system data and the continuity of service, solving the problem of inconvenient re-networking.

[0043] Embodiment 2

[0044] The embodiment continues to disclose the following based on the embodiment 1.

[0045] In step S1, the parameter information changed last time is synchronized to the sub-controller access point through the information synchronization channel, including: when the parameter information of the controller access point changes, it is synchronized to the sub-controller access point through the information synchronization channel, the sub-controller access point sends a parameter synchronization success message to the controller access point, if the sub-controller access point does not send the parameter synchronization success message or the controller access point does not receive the parameter synchronization success message, the parameter synchronization success message is re-sent, if the controller access point receives the parameter synchronization success message, it jumps to step S2.

[0046] As shown in Figure 2 The sub-controller access point and the controller access point access the same uplink gateway LAN side through wired access, the uplink gateway is connected with the network end, the sub-controller access point and the controller access point establish a wireless special information synchronization channel of the same VLAN, but the VLAN is different from the data service VLAN, so that the channel is isolated from the data service.

[0047] Step S3, after re-establishing the information synchronization channel of the controller access point and the sub-controller access point, it also includes: opening the Fronthaul-AP and Backhaul-AP interface of the controller access point, so that the terminal device accesses the controller access point through the Agent-AP.

[0048] Step S3, the sub-controller access point switches to the controller access point, including: after receiving the disconnection of the Sub-STA wireless VLAN sub-interface of the controller access point or not receiving the message from the Sub-STA wireless VLAN sub-interface within the preset time, the sub-controller access point switches to the controller access point.

[0049] The establishment method of the information synchronization channel includes: the sub-controller access point creates a Sub-AP wireless VLAN sub-interface, the controller access point creates a Sub-STA wireless VLAN sub-interface, and the Sub-STA wireless VLAN sub-interface is wirelessly connected to the Sub-AP wireless VLAN sub-interface. After the establishment of the wireless special information synchronization channel, the sub-controller access point closes the Fronthaul-AP and Backhaul-AP interface to prevent the terminal device from directly accessing the Agent-AP, and the controller access point sends the WAN configuration, LAN configuration, SSID, authentication mode, encryption type, password, topology information and other parameter information to the sub-controller access point for synchronization.

[0050] Embodiment 3

[0051] The embodiment continues to disclose the following based on the embodiments 1 and 2:

[0052] The sub-controller access point disconnects the terminal device and the Agent-AP from the controller access point after the information synchronization channel is established.

[0053] The controller access point and the sub-controller access point synchronize the parameter information of the controller access point through the information synchronization channel.

[0054] An EasyMesh network protection system is applied to a network switching method, the sub-controller access point and the controller access point access the same uplink gateway LAN side through a wired access, and the sub-controller access point and the controller access point establish the information synchronization channel of the same VLAN.

[0055] In the specific implementation process, when the controller access point fails, the controller access point sends the parameter information that has changed for the last time to the sub-controller access point, and confirms whether the information synchronization is successful. After confirming that the parameter synchronization is successful, the controller access point roams the Agent-AP hung thereunder to the sub-controller access point, and then the controller access point disconnects the Sub-STA, that is, disconnects the wifi, closes the Sub-STA, switches the role to the sub-controller access point, creates a Sub-AP wireless VLAN sub-interface, and switches the role to the controller access point after receiving the disconnection of the Sub-STA or not receiving a message from the Sub-STA within five minutes. The Sub-AP is closed, a Sub-STA wireless VLAN sub-interface is created, a wireless private information synchronization channel is established again, the Fronthaul-AP and the Backhaul-AP interfaces are opened, and the terminal device and the Agent-AP can access.
