[0049] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this invention.

[0050] It should be noted that in the description of this application, "multiple" is understood as "at least two". "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. A connected to B can represent: A and B directly connected, or A and B connected through C. Furthermore, in the description of this application, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order.

[0051] Furthermore, the data collection, dissemination, and use in the technical solution of this application all comply with the requirements of relevant national laws and regulations.

[0052] The following will describe in detail, with reference to the accompanying drawings, a message transmission method provided in the embodiments of this application.

[0053] First, the message transmission method provided in this application embodiment can be applied to dense WLAN scenarios, which can be composed of a wireless access controller AC+AP networking mode.

[0054] See Figure 1 The diagram illustrates a possible dense WLAN scenario according to an embodiment of this application. In this scenario, AP1 and AP2 are wireless access points connecting two different access switches, which are connected to the same network through a gateway and a core switch. Specifically, AP1 and AP2 are located in two adjacent BSSs, which constitute an OBSS. When AP1 and AP2 provide terminal services to multiple connected STAs within the OBSS, AP1 and AP2 compete for the shared channel resources within the OBSS.

[0055] Based on the above-mentioned dense WLAN scenarios, please refer to Figure 2As shown, this application embodiment provides a message transmission method, which can be executed by a wireless access point (AP). For example, it can be executed by AP1 or AP2 in the above-mentioned dense WLAN scenario, including:

[0056] S201: Receive beacon messages sent by neighboring wireless access points (APs).

[0057] Specifically, the adjacent AP is a wireless access point in an adjacent BSS that is in the same OBSS as the current device, wherein the current device is an AP or a STA.

[0058] For example, will Figure 1 If AP2 in the dense WLAN scenario shown is the current device, then AP1 in the dense WLAN scenario is the neighboring AP.

[0059] S202: Obtain the channel occupancy information of the terminal STA of the adjacent AP based on the beacon message.

[0060] Specifically, the beacon message carries STA channel occupancy information of adjacent APs, and the STA channel occupancy information includes at least the channel occupancy rate of each STA associated with the adjacent AP.

[0061] Optionally, STA channel occupancy information includes: the transmit tx channel occupancy rate and receive rx channel occupancy rate of each STA associated with an adjacent AP.

[0062] For example, assuming that AP1 is associated with STAs 1, 2, and 3, the STA channel occupancy information of AP1 carried in the beacon message can be shown in Table 1 below, based on the channel occupancy rate of each STA.

[0063] Table 1

[0064] Related STA TX channel occupancy rate (%) RX channel occupancy rate (%) STA1 4 31 STA2 5 32 STA3 4 31

[0065] S203: Obtain the channel occupancy resources of the adjacent APs based on the STA channel occupancy information of the adjacent APs.

[0066] Specifically, based on the radio air interface resources of the OBSS and the STA channel occupancy information of the adjacent APs, the channel occupancy resources of the adjacent APs are obtained.

[0067] For example, if the radio interface resources of the OBSS where AP1 and AP2 are located are 13.5KHz, and the average channel occupancy rate of each STA associated with AP1 is 37% as determined based on the above STA channel occupancy information, then the channel occupancy resource of AP1 is determined to be 5KHz according to the radio interface resources and STA channel occupancy information.

[0068] S204: Send a message response to the adjacent AP based on the channel occupancy resources.

[0069] Specifically, based on the channel resources occupied by neighboring APs in the OBSS, a message response is sent to the neighboring AP, including the following two cases:

[0070] Case 1: If the channel resources occupied by a neighboring AP exceed a preset threshold, a rate limiting notification message is sent to the neighboring AP.

[0071] Specifically, if the channel resources occupied by a neighboring AP exceed a preset threshold, the current device sends a rate limiting notification message to the neighboring AP to notify the neighboring AP to limit the rate of its own terminal service flow, thereby ensuring the QoS of the current device's terminal service. The terminal service flow may be, for example, the low-priority service flow of the neighboring AP. The rate limiting notification message may be sent using wired or wireless transmission methods.

[0072] For example, if AP1's channel resource usage exceeds a preset threshold, AP2 will send a rate limiting notification message to AP1 via wireless transmission to ensure the QoS of AP2's terminal services.

[0073] For example, if AP1's channel resource usage exceeds a preset threshold, AP2 can also send a rate limiting notification message to AP1 via wired transmission, thereby ensuring the transmission stability of the rate limiting notification message and effectively ensuring the QoS of AP2's terminal services.

[0074] Case 2: If the channel resource usage of the adjacent AP is not greater than the preset threshold, a beacon response message is sent to the adjacent AP.

[0075] Specifically, if the resources occupied by the adjacent AP channel do not exceed a preset threshold, that is, there is no need to limit the rate of the adjacent AP, then a beacon response message is sent to the adjacent AP. Optionally, in actual situations, it is also possible not to respond to the beacon message sent by the adjacent AP. This application does not restrict this.

[0076] For example, if the channel resources occupied by AP1 are not greater than a preset threshold, then AP2 sends a beacon response message to AP1 or does not respond to the beacon message sent by AP1.

[0077] In an optional embodiment, the beacon message sent by the neighboring AP to the current AP also carries the first STA count of the neighboring AP, wherein the first STA count is the number of STAs associated with the neighboring AP. Then, sending the rate limiting notification message to the neighboring AP includes:

[0078] Step 1: Calculate the minimum guaranteed bandwidth for adjacent APs based on the channel bandwidth information and the total number of STAs.

[0079] Step 2: Send a rate-limiting notification message carrying the minimum guaranteed bandwidth to the adjacent AP.

[0080] Specifically, the channel bandwidth information is the bandwidth information of the area channel of the OBSS. Then, based on the channel bandwidth information and the total number of STAs in the corresponding OBSS area, the minimum guaranteed bandwidth of the adjacent AP is calculated. The total number of STAs is obtained based on the first number of STAs carried in the beacon message and the second number of STAs carried by the current device. The first number of STAs is the number of STAs associated with the adjacent AP, and the second number of STAs is the number of STAs associated with the current device.

[0081] For example, if the channel bandwidth information of the OBSS area is 8MHz, and the number of STAs associated with AP1 is 3 and the number of STAs associated with AP2 is 5, then when the adjacent AP is AP1, the minimum guaranteed bandwidth is 1MHz.

[0082] It is worth noting that, in practice, the adjacent AP can also receive the beacon message sent by the current AP, thereby enabling the adjacent AP to obtain the second STA count of the current AP. Therefore, sending the rate limiting notification message to the adjacent AP also includes: directly sending the rate limiting notification message to the adjacent AP.

[0083] In this mode, the neighboring AP will calculate and store the total number of STAs between itself and the current AP based on the second number of STAs obtained. Thus, when the neighboring AP receives the rate limiting notification message sent by the current AP to the neighboring AP, the neighboring AP can calculate the corresponding minimum guaranteed bandwidth based on the recorded total number of STAs, thereby reducing the amount of data that the rate limiting notification message needs to carry and ensuring the stability of message transmission.

[0084] Based on the above method, a rate limiting notification message is sent to the adjacent AP, thereby notifying the adjacent AP to limit the rate of its own terminal service flow while ensuring that it is not less than the minimum guaranteed bandwidth, so as to ensure the QoS of the overall OBSS area.

[0085] In one optional embodiment, after sending a message response to the neighboring AP, the method further includes: recording and maintaining the STA channel occupancy information of the neighboring AP and the number of neighboring STAs in the local space to ensure the QoS of its own terminal services at all times.

[0086] See Figure 3The diagram shown is an interaction timing diagram for a possible application scenario provided in this application embodiment. This interaction timing diagram applies to AP1 and AP2, and for AP2, AP1 is its neighboring AP. Specifically, assuming that the channel resource occupancy of AP2 in the application scenario is greater than a preset threshold, the scenario includes:

[0087] S301: AP1 obtains the channel occupancy information and the number of STAs associated with AP1.

[0088] S302: AP1 sends a beacon message to AP2, wherein the beacon message carries the channel occupancy information of the STA associated with AP1 and the number of STAs.

[0089] S303: AP2 records and maintains the obtained STA channel occupancy information and number of STAs associated with AP1.

[0090] S304: AP2 obtains the channel occupancy information and the number of STAs associated with AP1, and obtains the channel occupancy resources and minimum guaranteed bandwidth of AP1.

[0091] S305: AP2 responds to AP1's channel resource usage exceeding a preset threshold by sending a rate limiting notification message to AP1.

[0092] S306: AP1 limits the rate of its own low-priority terminal service flows based on the rate limiting notification message.

[0093] Based on the above method, when AP1 occupies a lot of channel resources in the OBSS area, in response to the rate limiting notification message sent by AP2, AP1 reduces the channel resources it occupies, thereby ensuring the QoS of AP2's high-priority terminal services.

[0094] See Figure 4 The diagram shown illustrates an interaction timing diagram for another possible application scenario provided in this application embodiment. This interaction timing diagram applies to AP1 and AP2, and for AP2, AP1 is its neighboring AP. Specifically, assuming that the channel resource occupancy of AP2 in the application scenario does not exceed a preset threshold, the scenario includes:

[0095] S401: AP1 obtains the channel occupancy information and the number of STAs associated with AP1.

[0096] S402: AP1 sends a beacon message to AP2, wherein the beacon message carries the STA channel occupancy information and the number of STAs associated with AP1.

[0097] S403: AP2 records and maintains the obtained STA channel occupancy information and number of STAs associated with AP1.

[0098] S404: AP2 obtains the channel occupancy information and the number of STAs associated with AP1, and obtains the channel occupancy resources and minimum guaranteed bandwidth of AP1.

[0099] S405: AP2 responds to AP1 by sending a beacon response message if the channel resource usage of AP1 is not greater than a preset threshold.

[0100] S406: AP1 performs default processing based on the beacon response message.

[0101] Based on the above method, when AP1 receives a beacon response message, it is determined that AP1 has not occupied too many channel resources in the OBSS area, thereby ensuring the overall QoS of the terminal services of AP1 and AP2.
