DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0018] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0019] Reference Figure 1 The figure is a schematic diagram of the structure of a WiFi roaming distributed Internet speed limit system according to an embodiment of the present application.

[0020] The wifi roaming distributed Internet speed limit system 1 includes a wireless access point (Wireless Access Point, AP) 10 and an access controller (Wireless Access Point Controller, AC) 20. Among them, AP is the HUB in the traditional wired network and is also the most commonly used device when building a small wireless local area network. AP is equivalent to a bridge connecting the wired network and the wireless network. Its main function is to connect various wireless network clients together, and then connect the wireless network to the Ethernet, so as to achieve the purpose of network wireless coverage. AC is a network device used to centrally control the controllable wireless APs in the local area network and manage all wireless APs in the wireless network, including: issuing configurations, modifying relevant configuration parameters, radio frequency intelligent management, access security control, etc.

[0021] In some embodiments, the AC is provided with a wifi roaming distributed Internet access speed limiting device 30 for implementing a wifi roaming distributed Internet access speed limiting method.

[0022] In the embodiment of the present application, when processing a large number of roaming events and speed limit requirements, the roaming events of the mobile terminal accessing the mobile network are monitored in real time by the AC, the AP involved in the roaming path is dynamically determined, and a speed limit start message is constructed and sent to the speed limit AP according to the roaming path, thereby realizing accurate speed limit control of the mobile terminal during roaming. Compared with the prior art, the present application can eliminate a gateway device, and only requires AP+AC deployment to achieve the speed limit function of the user's mobile device.

[0023] Reference Figure 2 As shown, it is a flowchart of a wifi roaming distributed Internet access speed limiting method shown in an embodiment of the present application, and the wifi roaming distributed Internet access speed limiting method includes the following steps.

[0024] S21: When a roaming event of a target mobile terminal is received, a roaming path of the target mobile terminal is determined based on the roaming event.

[0025] S22: Determine a start AP and an end AP in the roaming path.

[0026] The target mobile terminal refers to any mobile terminal (ie, user mobile device) connected to the wireless network.

[0027] When it is detected that the STA (i.e., the target mobile terminal) is in a limited speed Internet access state at a certain AP (i.e., the starting AP, hereinafter referred to as APx) and roams to another AP (i.e., the ending AP, hereinafter referred to as APy), the AC can know that the target mobile terminal has generated a roaming event. Among them, the roaming process refers to the 802.11K / V / R protocol specification. 802.11K / V / R is also called the "fast roaming three protocols", which can effectively solve the problems of serious packet loss, untimely roaming triggering, and the selection of the roaming target is not the most suitable AP in the traditional roaming process. According to the 802.11K / V / R protocol specification, the AP can know that the target mobile terminal has sent a roaming message, and construct a roaming event to send to the AC. The content of the roaming event field can be defined as:

[0028] Combined Figure 3 In some embodiments, the AC is always in a waiting state to receive a roaming event occurring in the wireless network. Once the roaming event is received, the AC parses the roaming event and determines the roaming path, that is, obtains information about which access point the target mobile terminal roams from based on the content of the roaming event. Once the roaming path is obtained, the AC jumps to the next step S33.

[0029] In an optional implementation, before constructing the rate limit start message according to the start AP and the end AP, the method further includes: Determine whether the starting AP exists in the speed limit list; When it is determined that the starting AP does not exist in the speed limit list, the starting AP is added to the speed limit list, and the first time corresponding to the starting AP at the current moment is stored; When it is determined that the starting AP exists in the speed limit list, a second time corresponding to the starting AP in the speed limit list is updated based on the first time.

[0030] In some embodiments, once the AC resolves APx and APy in the roaming path, the APx information of APx is recorded in a preset speed limit list, and the timestamp of the current moment is saved at the same time, which is referred to as the first time. Specifically, when it is detected that the target mobile terminal is in a speed-limited Internet access state at APx, the AC first obtains the APx information of APx, and determines whether the APx information exists in the speed limit list based on the APx tag. When it is determined that the APx information does not exist in the speed limit list, the APx information is added to the speed limit list, and the first time of the current moment is recorded, that is, the time when the speed limit occurs on APx at the target mobile terminal. If the APx information exists in the speed limit list, it is only necessary to update the current timestamp corresponding to the APx information, that is, to update the second time originally recorded in the speed limit list to the first time, without the need for repeated recording. When it is determined that the recording or updating is completed, the AC jumps to the next step S34, that is, S23.

[0031] Through the above optional implementation, when processing a large number of roaming events and speed limit requirements, by judging whether the starting AP information already exists in the speed limit list, duplicate records are avoided, effectively saving storage space. At the same time, the timestamp of the starting AP in the speed limit list is updated in real time, ensuring the accuracy and timeliness of the speed limit information, optimizing the wireless network management efficiency, and improving the user experience. S23: Construct a rate limit start message according to the start AP and the end AP.

[0032] In some embodiments, the AC constructs a message for opening the speed limit based on the acquired roaming path information, i.e., the information that the target mobile terminal roams from APx to APy. The message for opening the speed limit includes multiple parameters, a parameter type (e.g., a string, a numeric type, etc.) corresponding to each parameter, and a parameter description. The multiple parameters may include a data key value, a maximum downlink bandwidth, and a maximum uplink bandwidth. In the embodiment of the present application, the data key value refers to the IP address of the target mobile terminal, and the message for opening the speed limit may be defined as:

[0033] S24: Send the speed limit activation message to the end AP, so that the end AP activates the speed limit function for the target mobile terminal based on the speed limit activation message.

[0034] In some embodiments, after AC completes the speed limit start message, it will send the speed limit start message to APy to implement speed limit management for the target mobile terminal after roaming. Specifically, AP receives the IP address and the upstream and downstream speed limit content, and calls the echo 'ip upstream downstream'> / proc / bandwidth instruction. The speed limit module in AP will fill the speed limit information into the hardware register, so that the chip will limit the speed of the specified IP.

[0035] After sending the message, the AC returns to step S21 and continues to wait for receiving the next roaming event.

[0036] Through the above-mentioned optional implementation methods, the present application monitors the roaming events of the target mobile terminal in real time, dynamically determines the starting AP and the ending AP in its roaming path, and constructs and sends a speed limit start message to the ending AP accordingly, thereby realizing precise speed limit control of the target mobile terminal during the roaming process, improving the flexibility and efficiency of wireless network management, ensuring the rational allocation and use of network resources, while also optimizing the user's Internet experience and avoiding network congestion caused by individual users occupying too much bandwidth.

[0037] In an optional embodiment, the method further comprises: Determine whether the waiting time meets the preset time threshold; When it is determined that the waiting time meets the preset time threshold, obtaining the speed limit list content of the speed limit list; Determine whether the speed limit list is empty; When it is determined that the speed limit list is empty, returning to execute the operation of determining whether the waiting time meets the preset time threshold; When it is determined that the speed limit list is not empty, determining whether the time difference between the first time and the second time satisfies the preset time threshold; When it is determined that the time difference does not meet the preset time threshold, returning to execute the operation of obtaining the speed limit list content of the speed limit list; When it is determined that the time difference meets the preset time threshold, a speed limit disable message is constructed, and the speed limit disable message is sent to the starting AP, so that the starting AP disables the speed limit function for the target mobile terminal based on the speed limit disable message.

[0038] Reference Figure 3In some embodiments, frequent roaming switching will cause roaming events to frequently pass through AC, and AC will start a timer and set the timer to a preset time threshold (for example, 5 seconds). After the timer is started, AC enters a waiting state until the timer time reaches the preset time threshold. After the time is reached, AC jumps to the next step S36. AC obtains the content of the speed limit list in the speed limit list and determines whether the speed limit list is empty. If the speed limit list is empty, it means that there is no mobile terminal that needs speed limit management at present. AC returns to step S35, restarts the timer and waits. If the speed limit list is not empty, jump to the next step S37, that is, obtain APx information in the speed limit list. Specifically, AC obtains the time information in the APx information from the speed limit list, including the new time information at the current moment (that is, the first time mentioned above) and the original time information stored in the speed limit list (that is, the second time mentioned above). After obtaining the time information, AC jumps to the next step S38 to determine whether the timestamp has timed out. AC determines whether the timestamp of the APx information recorded in the speed limit list differs from the current time by more than 5 seconds, that is, calculates the time difference between the first time and the second time, and determines whether the time difference is greater than the preset time threshold. If the timestamp has not timed out (that is, the time difference does not exceed 5 seconds), it means that the target mobile terminal may still be within the coverage of APy, and AC returns to step S36 to continue checking the contents of the speed limit list. If the timestamp has timed out (that is, the time difference exceeds 5 seconds), it means that the target mobile terminal may have left the coverage of APy or roamed to other APs, that is, the target mobile terminal has not roamed to the original AP device within the preset time threshold, and AC can send a speed limit rule command to close the target mobile terminal to the previous AP device, and AC jumps to the next step S39, that is, constructing and sending a speed limit closing message. AC constructs a speed limit closing message based on the APx information recorded in the speed limit list, and sends the speed limit closing message to APx to cancel the speed limit management of the target mobile terminal under APx. After sending the speed limit closing message, AC returns to step S35, restarts the timer and waits for the next cycle of inspection.

[0039] According to the same implementation manner as step S23, the AC can construct a message for closing the speed limit.

[0040] Through the above optional implementation, the AC receives, analyzes and processes roaming events, and implements speed limit management for mobile terminals during roaming. At the same time, through the setting of timers and the maintenance of speed limit lists, the timeliness and accuracy of speed limit management are ensured, and the network behavior of mobile terminals during roaming can be effectively controlled, thereby improving the stability and security of wireless networks.

[0041] Reference Figure 4In some embodiments, the AC can be triggered by preset conditions, that is, the AC automatically decides to turn on or off the speed limit function of the specified AP according to the internal logic or speed limit policy, or the web page trigger and the CLI command line trigger. Among them, the web page trigger means that the user turns on or off the speed limit function of the specified AP through the operation on the web page, refer to Figure 5 CLI command line trigger means that the user enters a command through the command line interface (CLI) to enable or disable the rate limit function of a specified AP.

[0042] Regardless of which speed limit triggering method is used, after receiving the trigger signal, the AC will update the speed limit list according to the trigger instruction, and record or modify the relevant information of the speed limit, such as the speed-limited AP, the speed-limited terminal, the speed limit rate, etc. After completing the update of the speed limit list, the AC jumps to the next step S42 or S43, depending on whether the trigger instruction is to turn on or off the speed limit.

[0043] In an optional embodiment, the method further comprises: When receiving the speed limit start instruction from the specified AP, a private message for starting the speed limit is constructed; The speed limit enabling private message is sent to the designated AP, so that the designated AP enables the speed limit function for the target mobile terminal based on the speed limit enabling private message.

[0044] Refer to Figure 4 In some embodiments, when a speed limit activation instruction is received, the AC constructs a speed limit activation private message based on the information in the speed limit list, that is, the speed limit function is only for the designated AP and the designated mobile terminal. The speed limit activation private message may include key information such as the AP identifier of the designated AP, the terminal identifier of the speed limit, and the speed limit rate. The AC sends the constructed speed limit activation private message to the designated AP via the wireless network. After receiving the speed limit activation private message, the designated AP parses the information in the speed limit activation private message and activates the speed limit function for the designated terminal based on the parsing result. After the speed limit function is activated, the designated AP continues to perform its original network communication tasks, and at the same time limits the network traffic of the designated terminal according to the speed limit setting.

[0045] In an optional embodiment, the method further comprises: When receiving the speed limit closing instruction from the designated AP, construct a speed limit closing private message; The speed limit disable private message is sent to the designated AP, so that the designated AP disables the speed limit function for the target mobile terminal based on the speed limit disable private message.

[0046] Refer to Figure 4In some embodiments, when a speed limit off instruction is received, that is, when the speed limit function under the specified AP needs to be turned off, the AC constructs a speed limit off private message based on the information in the speed limit list. The speed limit off private message also contains key information such as the AP identifier of the specified AP and the speed-limited terminal identifier. The AC sends the constructed speed limit off private message to the specified AP via the wireless network. After receiving the speed limit off private message, the specified AP parses the information in the speed limit off private message and turns off the speed limit function for the specified terminal based on the parsing result. After the speed limit function is turned off, the AP resumes normal network communication support for the specified terminal and no longer imposes traffic restrictions on it.

[0047] In some embodiments, when the AC sends a private message to enable speed limit to a designated AP so that the designated AP enables the speed limit function for the target mobile terminal, the AC records the sending time of the private message to enable speed limit, starts timing based on the sending time to obtain the speed limit activation time of the designated AP for the target mobile terminal, and compares the start speed limit time with a preset speed limit time threshold. When the speed limit activation time is greater than the preset speed limit time threshold, the designated AP can be ordered to disable the speed limit function for the target mobile terminal, that is, the AC constructs a private message to disable speed limit, and sends the private message to disable speed limit to the designated AP.

[0048] Through the above optional implementation, the speed limit management of the specified AP by the AC realizes the network traffic control of the specified terminal in the wireless network. Through multiple triggering methods such as preset condition triggering, web page triggering, and CLI command line triggering, users can flexibly turn on and off the speed limit function. At the same time, the update of the speed limit list ensures the accuracy and real-time nature of the speed limit information, which helps to improve the management efficiency and user experience of the wireless network.
