Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and more specifically, relates to a multi-router fast Mesh networking method and system. Background Art

[0002] Since 5G transmission efficiency is higher, dual-band routers generally choose 5G as the backhaul link (BackhaulLink) of Mesh networking. Wireless networking between two routers is generally achieved by pressing the WPS (Wi-Fi Protected Setup) button. The main process includes:

[0003] Select a router to connect to the external network as the master device, select another router as the slave device, and press the WPS button on both simultaneously or in sequence.

[0004] When the master device presses the WPS button, it broadcasts a beacon packet. When the slave device receives this information, it indicates that there is a connected router, and the slave device sends a request to associate with it. After associating with the forward network (Fronthaul BSS) of the master device, it obtains the authentication information of the master device's backhaul link through the M1 to M8 messages of the WPS protocol, including SSID (Service Set Identifier), authentication encryption method, and password. After the slave device obtains this information, it disconnects from the forward network of the master device, and then uses this information to implement the authentication association of the master device's backhaul link. This process is called Onboarding.

[0005] After the master and slave devices complete Onboarding, the WPS process ends. After the slave device connects to the master device's backhaul link, it requests the master device to send configuration information to the slave device. The slave device configures the local interface according to the received configuration information to complete the network configuration synchronization.

[0006] From the WPS process, it can be seen that if a slave device wants to join the Mesh network, it can only perform WPS interaction with the master device one-to-one. New slave devices are allowed to join the WPS only after the Onboarding process is completed. Assuming that there are currently multiple slave devices that need to join, they can only be completed sequentially. This significantly prolongs the networking time and poor user perception. Summary of the invention

[0007] The present invention aims at the limitation of WPS networking and proposes a method for quickly adding multiple devices to a Mesh network. Based on the WPS protocol, the process is optimized to enable multiple devices to press the WPS button at the same time and quickly join the Mesh network of the main device within one cycle.

[0008] To achieve the above object, according to one aspect of the present invention, a multi-router fast Mesh networking method is provided, comprising:

[0009] The master device divides the frequency band into multiple resource channels RU according to the bandwidth of the current frequency band;

[0010] The master device broadcasts a beacon packet during the WPS process and adds a RU support flag bit in the extension field of the beacon packet;

[0011] According to the order in which the Probe Request packets of the slave devices are received, the master device sequentially allocates resource channels RU to the slave devices, and notifies the slave devices to establish association with the master device on the resource channels RU allocated to them; wherein the Probe Request packet of the slave device is replied after receiving the Beacon packet with the RU support flag bit broadcast by the master device, and the Probe Request packet also includes the RU support flag bit;

[0012] The master device exchanges data messages with the slave device on each resource channel RU of the associated slave device.

[0013] In one embodiment of the present invention, the master device performs data message interaction with the slave device on each resource channel RU of the associated slave device, specifically:

[0014] The master device publishes the MSG1 data message on each resource channel RU to inform the slave device that the backhaul link interaction process has started;

[0015] The master device receives the MSG2 data message sent by the slave device, wherein the MSG2 data message is sent to the master device after the slave device receives the message on the corresponding resource channel RU, and contains relevant information of the slave device;

[0016] After receiving the MSG2 data message from the slave device, the master device records the relevant information of the slave device and replies with a MSG3 data message on each resource channel RU. The MSG3 data message includes the SSID and encrypted authentication information of the Backhaul BSS of the master device.

[0017] The master device simultaneously sends a Deauthentication message to each slave device on each resource channel RU, disconnects the Fronthaul connection with the slave device, receives the Backhaul information obtained by the slave device through the MSG3 data message, and initiates association authentication to the Backhaul of the master device, thereby completing the Onboarding of multiple slave devices at the same time.

[0018] In one embodiment of the present invention, the master device allocates a resource channel RU to the slave device, and notifies the slave device to establish an association with the master device on the resource channel RU allocated to it, specifically:

[0019] After receiving the Probe Request packet from the slave device, the master device records the information of the slave device and replies with a ProbeResponse;

[0020] After receiving the Association Request sent by the slave device, the master device replies with the Association Response to complete the association with the forward network of the slave device, and subsequently transmits the return link authentication message on the resource channel RU corresponding to the RU sequence number; wherein the Association Request is sent by the slave device to the master device after receiving the Probe Response of the master device.

[0021] In one embodiment of the present invention, during the WPS process, the master device allocates resource channels RU only to slave devices that meet the requirements, specifically: the RU flag bit is a preset value, and the signal strength of the slave device is greater than the preset strength.

[0022] In one embodiment of the present invention, during the WPS process, the master device allocates resource channels RU to the slave devices in sequence according to the order in which the Probe Request packets from the slave devices are received. When the RU sequence number = the total number of RUs, if the master device still receives a new Probe Request packet from the slave device, it directly replies with overlap information to the slave device.

[0023] In one embodiment of the present invention, the master device also starts a timer when starting the WPS process. When the timer is reached or canceled, if a new Probe Request packet from a slave device is received at this time, an overlap reply is directly sent to the slave device to inform the slave device that WPS interaction cannot be performed at this time and please try again later.

[0024] In one embodiment of the present invention, the relevant information of the slave device includes: the SSID and MAC message of the Fronthaul AP of the slave device.

[0025] According to another aspect of the present invention, a multi-router quick Mesh networking method is also provided, comprising:

[0026] During the WPS process, the slave device scans each channel of the frequency band. When receiving the beacon packet from the master device, it sends a Probe Request packet to the master device, and carries the RU support flag. The Probe Request packet of the slave device is replied after receiving the beacon packet with the RU support flag broadcast by the master device.

[0027] After receiving the Probe Response packet containing the RU sequence number from the master device, the slave device sends an Association Request to the master device, and completes the association of the master device's forward network after the master device replies with an Association Response, and waits for the master device to subsequently transmit a return link authentication message on the corresponding resource channel RU;

[0028] The slave device exchanges data messages with the master device on the corresponding resource channel RU associated with the master device.

[0029] In one embodiment of the present invention, the slave device performs data message interaction with the master device on the corresponding RU resource channel associated with the master device, specifically:

[0030] After receiving the MSG1 data message sent by the master device on its corresponding resource channel RU, the slave device sends a MSG2 data message to the master device, which includes the SSID and MAC information of the Fronthaul AP of the slave device; wherein the MSG1 data message is sent by the master device to inform the slave device that the backhaul link interaction process starts;

[0031] The slave device receives the MSG3 data message sent by the master device on its corresponding resource channel RU, wherein the MSG3 data message includes the SSID and encrypted authentication information of the Backhaul BSS of the master device;

[0032] The slave device receives the Deauthentication message sent by the master device on its corresponding resource channel RU, disconnects the Fronthaul connection with the master device, and initiates association authentication to the Backhaul of the master device through the Backhaul information obtained by MSG3, thereby completing Onboarding with the master device.

[0033] According to another aspect of the present invention, a multi-router fast Mesh networking system is also provided, comprising a master device and multiple devices, wherein the master device is used to execute the multi-router fast Mesh networking method on the master device side, and the slave device is used to execute the multi-router fast Mesh networking method on the master device side.

[0034] In general, the above technical solution conceived by the present invention has the following beneficial effects compared with the prior art:

[0035] Compatible with different devices, supporting both normal WPS networking process with normal devices and optimized networking process with devices that meet RU division requirements;

[0036] For devices that support RU division, multiple slave devices can be added to the Mesh network at the same time within one networking cycle. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] OFDMA (Orthogonal Frequency Division Multiple Access) is a multi-user transmission technology introduced by WiFi6, which divides the channel into smaller resource units (RU). Through OFDMA resource subdivision, multiple clients can occupy different RU resources for parallel transmission, greatly improving multi-user performance.

[0045] In order to solve the problems existing in the prior art, the present invention proposes a multi-router fast Mesh networking method for the WPS networking limitation. Based on the WPS protocol, the process is optimized to enable multiple devices to press the WPS button at the same time and quickly join the Mesh network of the main device within one cycle, that is:

[0046] Based on the WPS protocol, the association between the master device and the slave device is completed (the slave device is connected to the forward network of the master device);

[0047] Optimize the WPS protocol to allow multiple slave devices to associate with the master device through WPS within a certain period of time (excluding subsequent WPS protocol interactions);

[0048] Drawing on OFDMA technology, multiple RUs are divided on the current channel and bandwidth resources of the master device (for example, if the bandwidth is 80M and each RU occupies 20M, then 4 RUs can be divided). Backhaul authentication information is transmitted simultaneously with different slave devices on the corresponding RU, and finally the Onboarding process of multiple (up to 4 at 80M bandwidth) slave devices is completed at the same time.

[0049] The master device divides the frequency band into multiple resource channels RU according to the bandwidth of the current frequency band, and each resource channel occupies 20M bandwidth. Assuming that the current bandwidth of the master device is 80M, it is divided into 80 / 20 = 4 RUs, marked as RU1 to RU4 in sequence. At this time, a maximum of 4 slave devices are allowed to make networking requests at the same time.

[0050] like Figure 1 As shown in the figure, the main device is Fronthaul AP (for mobile phone and other terminal access) + Backhaul BSS (for backhaul link), and the sub-device is Fronthaul STA in the WPS stage, and Fronthaul AP (for mobile phone and other terminal access) + Backhaul STA after the networking is completed. The solid line indicates that the sub-device is first associated with the forward network of the main device in the WPS stage, and the dotted line is the backhaul link established between the sub-device and the main device after the subsequent Onboarding process is completed, that is, the networking is completed.

[0051] First, from the perspective of the master device, Figure 2 As shown, the present invention provides a multi-router fast Mesh networking method, comprising:

[0052] S11, the master device divides the frequency band into multiple resource channels RU according to the bandwidth of the current frequency band;

[0053] S12, the master device broadcasts a beacon packet during the WPS process, and adds a RU support flag bit in the extension field of the beacon packet;

[0054] S13. The master device allocates resource channels RU to the slave devices in turn according to the order in which the Probe Request packets from the slave devices are received, and notifies the slave devices to establish association with the master device on the resource channels RU allocated to them; wherein the Probe Request packet of the slave device is replied after receiving the beacon packet with the RU support flag bit broadcast by the master device, and the Probe Request packet also includes the RU support flag bit;

[0055] S14. The master device exchanges data messages with the slave device on each resource channel RU of the associated slave device.

[0056] Furthermore, the master device exchanges data messages with the slave device on each resource channel RU of the associated slave device, specifically:

[0057] The master device publishes the MSG1 data message on each resource channel RU to inform the slave device that the backhaul link interaction process has started;

[0058] The master device receives the MSG2 data message sent by the slave device, wherein the MSG2 data message is sent to the master device after the slave device receives the message on the corresponding resource channel RU, and contains relevant information of the slave device;

[0059] After receiving the MSG2 data message from the slave device, the master device records the relevant information of the slave device and replies with a MSG3 data message on each resource channel RU. The MSG3 data message includes the SSID and encrypted authentication information of the Backhaul BSS of the master device.

[0060] The master device simultaneously sends a Deauthentication message to each slave device on each resource channel RU, disconnects the Fronthaul connection with the slave device, receives the Backhaul information obtained by the slave device through the MSG3 data message, and initiates association authentication to the Backhaul of the master device, thereby completing the Onboarding of multiple slave devices at the same time.

[0061] Further, the master device allocates a resource channel RU to the slave device, and notifies the slave device to establish an association with the master device on the resource channel RU allocated to it, specifically:

[0062] After receiving the Probe Request packet from the slave device, the master device records the information of the slave device and replies with a ProbeResponse;

[0063] After receiving the Association Request sent by the slave device, the master device replies with the Association Response to complete the association with the forward network of the slave device, and subsequently transmits the return link authentication message on the resource channel RU corresponding to the RU sequence number; wherein the Association Request is sent by the slave device to the master device after receiving the Probe Response of the master device.

[0064] Furthermore, during the WPS process, the master device allocates resource channels RU only to slave devices that meet the requirements, specifically: the RU flag bit is a preset value, and the signal strength of the slave device is greater than the preset strength.

[0065] Furthermore, during the WPS process, the master device allocates resource channels RU to the slave devices in sequence according to the order in which the Probe Request packets from the slave devices are received. When the RU sequence number = the total number of RUs, if the master device still receives a new Probe Request packet from the slave device, it directly replies with overlap information to the slave device.

[0066] Furthermore, the master device also starts a timer when starting the WPS process. When the timer is reached or canceled, if a new Probe Request packet from a slave device is received at this time, it directly replies overlap to the slave device, informing the slave device that WPS interaction cannot be performed at this time and please try again later.

[0067] Furthermore, the relevant information of the slave device includes: SSID and MAC information of the Fronthaul AP of the slave device.

[0068] From the perspective of equipment, Figure 3 As shown, the present invention provides a multi-router fast Mesh networking method, comprising:

[0069] S21. The slave device scans each channel of the frequency band during the WPS process. When receiving the beacon packet of the master device, it sends a Probe Request packet to the master device, and carries the support RU flag. The Probe Request packet of the slave device is replied after receiving the beacon packet with the RU support flag broadcast by the master device.

[0070] S22, after receiving the Probe Response packet containing the RU sequence number sent by the master device, the slave device sends an Association Request to the master device, and completes the association of the master device's forward network after the master device replies with an Association Response, and waits for the master device to subsequently transmit a return link authentication message on the corresponding resource channel RU;

[0071] S23. The slave device exchanges data messages with the master device on the corresponding resource channel RU associated with the master device.

[0072] Further, the slave device interacts with the master device via data messages on the corresponding RU resource channel associated with the master device, specifically:

[0073] After receiving the MSG1 data message sent by the master device on its corresponding resource channel RU, the slave device sends a MSG2 data message to the master device, which includes the SSID and MAC information of the Fronthaul AP of the slave device; wherein the MSG1 data message is sent by the master device to inform the slave device that the backhaul link interaction process starts;

[0074] The slave device receives the MSG3 data message sent by the master device on its corresponding resource channel RU, wherein the MSG3 data message includes the SSID and encrypted authentication information of the Backhaul BSS of the master device;

[0075] The slave device receives the Deauthentication message sent by the master device on its corresponding resource channel RU, disconnects the Fronthaul connection with the master device, and initiates association authentication to the Backhaul of the master device through the Backhaul information obtained by MSG3, thereby completing Onboarding with the master device.

[0076] Furthermore, the present invention also provides a multi-router quick Mesh networking system, comprising a master device and multiple devices, wherein the master device is used to execute the multi-router quick Mesh networking method on the master device side, and the slave device is used to execute the multi-router quick Mesh networking method on the master device side.

[0077] like Figure 4 As shown, the specific implementation process of the multi-router fast Mesh networking method of the present invention is:

[0078] The master and slave devices start the WPS process (for example, pressing the WPS buttons of the master device and multiple slave devices in sequence). After pressing the WPS button, the master device starts the timer and broadcasts a beacon packet at the same time, adding a RU support flag bit in the extended field of the beacon packet.

[0079] After pressing the WPS button, device A scans each channel of the frequency band (the 5G frequency band is taken as an example in the embodiment of the present invention, and all OFDMA wifi standards can be supported, including the current wifi6, wifi7 and subsequent evolution forms). When receiving the beacon packet of the master device, it sends a Probe Request packet to the master device and carries the support RU mark bit.

[0080] After receiving the Probe Request packet from slave device A, the master device checks the RU flag bit and the signal strength of the slave device. If the requirements are met (the RU flag bit is a preset value (for example, 1), and the signal strength is greater than a preset strength value (for example, -40dBm)), the master device records the information of the slave device (including device Mac, etc.) and replies with a Probe Response, carrying the RU serial number RUIndex. At this time, RUIndex = 1.

[0081] After receiving the Probe Response from the master device, the slave device sends an Association Request to the master device, and completes the association of the master device's forward network after the master device replies with an Association Response, and waits for the master device to subsequently transmit a return link authentication message on RU1.

[0082] When the master device continues to receive the Probe Request packet from the slave device B, it will directly send overlap information to the slave device B and interrupt the networking process according to the normal WPS protocol process. This process is removed after optimization here, and the RU mark bit of the slave device B and the signal strength of the slave device are checked as before. After meeting the requirements, the RU sequence number is updated (RUIndex=2 at this time), and the slave device B is informed through the Probe Response. After receiving the message, the slave device B completes the management and waits on RU2 for the master device to transmit the return link information message.

[0083] When the RU number RUIndex = the total number of RUs RUTotal, if the master device still receives the ProbeRequest packet from the slave device, it will directly reply with the overlap information. (That is, during the WPS process, the master device notifies the slave device to communicate on RUIndex+1 after receiving a ProbeRequest from the slave device, and refuses when the maximum RU value (RUTotal) is exceeded).

[0084] When the timer (this timer is not the WPS timeout timer, but another new timer (for example, 30s), during which multiple slave devices are allowed to associate with the master device through the WPS protocol, and WPS protocol association is no longer allowed after this time) expires, the master device exchanges data messages with the slave device on each RU resource channel of the associated slave device.

[0085] The master device first publishes the MSG1 data message on each RU to inform the slave device that the backhaul link interaction process has started. After receiving the message on the corresponding RU, each slave device sends the MSG2 data message to the master device, which contains the SSID and MAC information of the slave device's Fronthaul AP.

[0086] After receiving MSG2 from the slave device, the master device records the SSID and MAC message of the fronthaul AP of the slave device, and replies with MSG3 data message on each RU, including the SSID and encryption authentication information of the backhaul. After receiving the message, the slave device saves it.

[0087] Next, the master device sends a Deauthentication message to each slave device on each RU at the same time, and the slave device disconnects from the Fronthaul connection of the master device, and initiates association authentication to the Backhaul of the master device through the Backhaul information obtained by MSG3, thereby completing the Onboarding of multiple slave devices at the same time.

[0088] When the timer is reached or canceled, if the slave device still receives a Probe Request packet, it will directly reply with "overlap" to inform the slave device that WPS interaction is not possible at this time and please try again later.

[0089] It should be noted that, in the present invention, the WPS protocol is used to complete the forward network association between the slave device and the master device, and the subsequent MSG1 to Deauthentication are completed on the resource channel RU allocated by the master device.

[0090] against Figure 5 , after pressing the WPS button, the master device starts the timer, broadcasts the WPS beacon message, and listens to the Probe Request message of the slave device. When the first message from the slave device is received within the timer, the message is parsed to see if it supports RU fragmentation. If it supports and meets the signal strength requirements, the multi-terminal networking process is performed, otherwise the normal WPS pairing process is performed and the timer is canceled. The multi-terminal networking process first informs the slave device of the corresponding RU resource information and completes the association of the slave device. When receiving messages from other slave devices later, if the slave device also meets the RU fragmentation and signal strength requirements, the slave device information is saved and the WPS association is completed. Otherwise, the slave device Overlap is directly notified, and the slave device WPS process ends. When the timer expires, the master device no longer receives new Probe Request messages from the slave device. The master device simultaneously sends the backhaul link authentication information to multiple saved slave devices on the RU agreed with the slave device, so that multiple slave devices can quickly complete the Onboarding process.

[0091] against Figure 6 After pressing the WPS button, the slave device obtains the RU resources for subsequent interactions and completes the forward network association with the master device. After the slave device receives the master device's backlink link authentication information and Deauthentication on the corresponding RU, it disconnects the forward network connection with the master device and completes the Onboarding process.

[0092] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
