Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a terminal access method, device, storage medium and wireless access equipment. Background Art

[0002] In order to better meet the deployment requirements of large wireless networks, a solution of wireless controller (AC) and wireless access point (AP) is proposed. In this solution, AP, as the front-end device, is deployed in different locations. Its main function is to expand the coverage of network signals. AC, as the back-end core device, is responsible for establishing communication connections with these APs scattered in different locations and centrally controlling these APs. The two work together to ensure the stable operation and security of the entire wireless network.

[0003] However, with the rapid growth of mobile devices and IoT terminals, the demand for wireless access in public places, conference centers, stadiums and other scenarios has exploded. In such a high-density environment, some APs need to handle access and communication requests from multiple terminals at the same time. Traditional access methods do not have an effective access control mechanism, and are limited by the bandwidth and capacity of APs, which leads to connection drops and unstable access in high-concurrency situations.

[0004] The existing solution is to increase the number of APs deployed in high-density scenarios, allowing terminals to connect to different APs to share the pressure of APs and achieve load balancing, which requires increasing the cost of APs. However, as the number of APs increases, channels will overlap between APs, and devices may frequently switch to different APs. Summary of the invention

[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0059] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0060] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0061] In the description of the present application, it should be noted that the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance. In addition, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0062] Based on the above statement, as introduced in the background technology, in a high-density environment of mobile devices and IoT terminals, in order to cope with high concurrency, connection drops and unstable access are prone to occur. The conventional solution of increasing the number of AP deployments will not only increase hardware costs, but too many APs will also cause channel overlap.

[0063] Based on the discovery of the above technical problems, the inventors have proposed the following technical solutions to solve or improve the above problems through creative work. It should be noted that the defects in the solutions in the above prior art are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in the embodiments of the present application for the above problems below should all be the contributions made by the inventors to the present application in the process of invention and creation, and should not be understood as technical contents known to those skilled in the art.

[0064] In view of the above technical problems, this embodiment provides a terminal access method. In the method, a wireless access device receives detection requests from multiple terminals; divides the multiple terminals into multiple terminal groups; and sequentially establishes communication connections with the terminals in each terminal group. In this way, for a large number of terminals accessing in a short period of time, orderly communication connections are established with these devices, thereby improving the stability of a large number of terminals accessing.

[0065] It should be noted that the wireless access device implementing the method may be any device that can provide a wireless access function. For example, the wireless access device may not only be the above-mentioned AP, but also a wireless router that integrates AC and AP.

[0066] To make the solution provided by this embodiment clearer, the following uses AP as a wireless access device to implement the method, and combines Figure 1 Each step of the method is described in detail. However, it should be understood that the operations of the flowchart may not be implemented in order, and steps without logical contextual relationships may be reversed in order or implemented simultaneously. In addition, those skilled in the art may add one or more other operations to the flowchart, or may remove one or more operations from the flowchart under the guidance of the content of this application.

[0067] Considering that the present implementation involves a wireless network access process of a terminal, in order to make the scheme to be introduced easier to understand, the process of establishing a communication connection between a single terminal and an AP is described in detail below, taking AP as an example of the wireless access device of the present invention.

[0068] When the terminal turns on the wireless function, it will actively scan the surrounding wireless signals to find available APs. During this process, the terminal will send a probe request, namely a Probe Request frame. The Probe Request frame is a wireless management frame used to query whether there are available APs around and obtain relevant information about the APs.

[0069] When the AP receives the Probe Request frame sent by the terminal, it will check its own configuration information to determine whether to allow the connection with the terminal. If allowed, the AP will send a probe response, namely a Probe Response frame. The Probe Response frame contains information such as the AP's SSID, supported rates, encryption methods, and signal strength.

[0070] If the terminal receives Probe Response frames from multiple APs, it will select the most suitable AP for connection based on factors such as signal strength, encryption method, network configuration, etc. Therefore, after determining the target AP, the terminal will send an Association Request frame to request to establish an association with the target AP.

[0071] After receiving the association request, the target AP will check the terminal's authentication information. If the authentication is successful, the target AP will send an association response, namely an Association Response frame, to confirm the association with the terminal. After receiving the association response, the terminal will perform corresponding network settings according to the configuration sent by the target AP, such as IP address allocation, DNS server, etc. At this point, the communication connection between the terminal and the target AP is successfully established.

[0072] Based on the above implementation, the process of establishing a communication connection between a single terminal and an AP is introduced, such as Figure 1 As shown, the method provided by the implementation includes:

[0073] S1, receiving detection requests from multiple terminals.

[0074] Among them, the probe request is a Probe Response frame initiated by the terminal when accessing the wireless network. In addition, in this embodiment, the AP presets a time period, and multiple terminals initiate probe requests to the AP during this time period. Assuming that the duration of the time period is 10ms, after the AP receives the probe request from the first terminal, it starts to count the terminals that initiate probe requests within the next 10ms. It can be understood that when the AP receives the probe request from the first terminal, a 10-millisecond timer will be started. During this period, all terminals that initiate probe requests to the AP will be recorded. Exemplary:

[0075] Terminal A sends a probe request at 0th millisecond, triggering the timer.

[0076] Terminal B sends a probe request at the 2nd millisecond.

[0077] Terminal C sends a probe request at the 5th millisecond.

[0078] Terminal D sends a probe request at the 8th millisecond.

[0079] Terminal E sends a probe request at the 12th millisecond, but the timer has expired at this time, so the probe request of device E will not be counted in this statistics.

[0080] Based on the introduction of the multiple terminals and the detection request in step S1 in the above embodiment, continue to refer to Figure 1 , the method further comprises:

[0081] S2, dividing the multiple terminals into multiple terminal groups.

[0082] In this regard, this embodiment provides multiple division methods. In order to respond to the terminal that initiates the earliest detection request as soon as possible, in one of the division methods, the AP obtains a first ranking result of the multiple terminals according to the sequence of the detection requests of the multiple terminals; and divides the multiple terminals into multiple terminal groups according to the first ranking result.

[0083] Exemplarily, it is assumed that each terminal group includes at most 10 terminals. When the AP detects that a large number of terminals request access, the multiple terminals can be sorted according to the time sequence in which the terminals send out the detection requests, and then the terminals are grouped into groups of 10 according to the sorting results. If there are less than 10 terminals left at the end, these terminals will also be divided into an independent terminal group. In this way, the AP can group the terminals that send out requests at the same time or close in time into the same group. If the multiple terminal groups are responded to in sequence according to their sorting, the terminals that initiate the detection requests early can be responded to first, thereby improving the response efficiency of the system and the user experience.

[0084] In another embodiment, considering that the terminal usually selects the nearest AP as the access point of the wireless network, and the terminal at a longer distance will select other APs closer to itself as the access point of the wireless network. Therefore, the AP can also obtain a second sorting result of the multiple terminals according to the signal strength of the detection requests of the multiple terminals; and divide the multiple terminals into multiple terminal groups according to the second sorting result.

[0085] Exemplarily, it is continued to be assumed that each terminal group includes a maximum of 10 terminals. When the AP detects that a large number of terminals have requested access, the multiple terminals can be sorted according to the signal strength of the detection request sent by the terminal, that is, the stronger the signal means the closer to the AP, and vice versa. Then, the AP groups them into groups of 10 according to the sorting results. At the end of the division, there may be less than 10 terminals left, which are also divided into 1 terminal group. In this way, the terminals with higher signal strength can be divided into the same group. If the responses are made in sequence according to the ranking of multiple terminal groups, the terminals with closer distances can be responded to first.

[0086] It should be noted that each terminal has its own device identification, and the above-mentioned sorting and grouping of terminals is based on the terminal identification as the processing object. Figure 1 , the method further comprises:

[0087] S3, establish communication connection with the terminals in each terminal group in turn.

[0088] For example, it is further assumed that each terminal group includes 10 terminals. Figure 2 As shown in the figure, the AP is connected to the AC for communication. The AP will sort the terminals according to the time sequence of receiving the probe request and group the sorted terminals. For each terminal group in the figure, the 10 terminals are represented as STA_1 to STA_10. In this example, the time sequence is measured by the number of clock interruptions (jiffers). Therefore, for the first terminal group, it can be assumed that the jiffers for receiving the probe request from terminal STA_1 is 800001, the jiffers for receiving the probe request from terminal STA_2 is 800002, and the jiffers for receiving the probe request from terminal STA_3 is 800003.

[0089] Then, AP is Figure 2 Each terminal group is assigned a specified time window, and a polling cycle duration is set, and the access request of the terminal in a terminal group is processed within this cycle duration. Therefore, the AP can first send a response frame of the probe request, that is, a Probe Response frame, to the terminal in the first terminal group, indicating that the first terminal group can send an access request within this time window. Only the terminal that receives the response frame is allowed to authenticate and associate with the AP within this cycle. Then, after the time window allocated to the first terminal group ends, the AP continues to send a response frame of the probe request to the terminal in the second terminal group, indicating that the second terminal group can send an access request within this time window. Only the terminal that receives the response frame is allowed to authenticate and associate with the AP within this cycle. And so on, each terminal group is polled until the communication interaction of accessing the wireless network is performed with the terminal in the last terminal group. In this way, through the above implementation, for a large number of terminals accessed in a short period of time, by establishing orderly communication connections with these devices, the stability of a large number of terminals when accessing is improved.

[0090] In addition, as described in the background technology, in an environment with high terminal density, some APs need to process access and communication requests from multiple terminals at the same time, which may cause connection drops and unstable access. Figure 3 As shown, in Figure 1 Between steps S1 and S2, the following is also included:

[0091] S1.5, determine whether the number of the multiple terminals is greater than a number threshold.

[0092] If yes, then step S2 is executed, otherwise, there is no need to group the multiple terminals, and the detection requests of the multiple terminals can be processed according to the traditional access method. In this embodiment, 30 can be used as the quantity threshold.

[0093] In addition, it is also found in practice that after receiving the Probe Request frame sent by the terminal, the AP will follow a series of steps to encapsulate the Probe Response frame, including: setting the frame control field, address field, sequence control field, timestamp, capability information field, SSID element, supported rate, DSSS parameter set and other optional elements. After these steps are completed, the AP encapsulates all information into a Probe Response frame according to the 802.11 protocol and sends it to the requesting terminal through a wireless signal. When a large number of terminals need to be responded to, the above method is used to construct the Probe Response frame for each terminal, which will cause a large delay.

[0094] In this regard, this embodiment provides a response template to improve the response efficiency. Figure 3 ,exist Figure 1 Between steps S2 and S3, the method provided in this embodiment further includes:

[0095] S2.5, record the terminal characteristic information of each terminal.

[0096] The terminal characteristic information of each terminal includes the MAC address and signal strength of the terminal. In a specific implementation, the AP may apply for a cache space in a memory and record the terminal characteristic information of each terminal into the cache space.

[0097] Based on the terminal feature information of each terminal, continue to refer to Figure 3 , this implementation also provides the following optional implementation of step S3:

[0098] S3-1, for each terminal group, a response frame is constructed for each terminal in the terminal group according to a preset response template and terminal feature information of each terminal in the terminal group.

[0099] In this regard, the AP may fill the terminal feature information of each terminal in the terminal group into a preset position of the response template to obtain a response frame of each terminal in the terminal group.

[0100] S3-2, sending a corresponding response frame to each terminal in the terminal group.

[0101] The response frame is used to instruct the corresponding terminal to interact with the wireless access device to establish a communication connection.

[0102] For example, taking the Probe Response frame as an example, the AP caches dynamic information such as the terminal's MAC address and signal strength. When the AP needs to reply to the Probe Response frame, it only needs to take out the dynamic information from the cache, fill in the corresponding position of the response template, and then send it to the terminal immediately. In this way, the complex process of regenerating and parsing the management frame every time is avoided, thereby significantly improving the response efficiency of the AP. After receiving the Probe Response frame, each terminal can perform subsequent authentication and association with the AP, thereby accessing the wireless network provided by the AP.

[0103] Based on the same inventive concept as the terminal access method provided in this embodiment, this embodiment also provides a terminal access device, which includes at least one software function module that can be stored in the memory 120 or fixed in the wireless access device in the form of software.

In addition, since the invention concept is the same as that of the terminal access method, the terminal access device can also implement other steps or sub-steps of the method through the modules, which will not be described in detail in this embodiment.
