Description
Technical Field
The present invention relates to the field of wireless network technologies, and in particular, to a method and an apparatus for configuring 5G priority access based on multiple APs, and a computer-readable storage medium.
Background
With the popularization of wireless networks, wireless users are increasing, and many of the users use dual-band wireless terminals capable of supporting both 2.4G frequency bands and 5G frequency bands. Since 5.8GHz (5G for short) generally has more available channels, less interference and less number of terminals than 2.4GHz, the 5G priority function can enable the user to preferentially connect to the Service Set Identifier (SSID) of 5GHz, thereby obtaining better Wireless Local Area Network (WLAN) experience.
The WLAN mainly includes Stations (STA), Access Points (AP), Wireless Medium (WM), and a Distribution System (DS). STAs are typically terminals in a WLAN.
The 5G priority function is typically implemented on the AP, with the following implementation logic: first the AP needs to confirm whether the STA terminal type supports only 2.4G or simultaneously supports 5G. In order to give the AP enough time to confirm whether the STA supports 5G, the AP generally does not respond to the first 2 to 3 probe-request messages sent by the STA when the type of the STA is not known, so as to give the STA sufficient time to send a 5GHz probe-request message. If the AP opens the 5G priority and finds that the STA sending the probe-req supports dual-frequency, the AP cannot immediately respond to the probe-response or send a rejected probe-response, the rejection reason is busy, and the STA is not expected to be continuously connected with the 2.4G SSID after receiving the message. The STA finds that only the SSID of 5G is present in the SSID list in the scanning result, but no SSID of 2.4G is present, so that the STA preferentially connects to the SSID of 5G.
Of course, since there are many types of terminals and the algorithms of the terminals are not consistent, there may be a phenomenon that although the AP does not respond to the 2.4G protocol-response or returns the probe-response with the reject reason, the STA does not switch to the 5G SSID connection and continues to send the probe-request to the 2.4G SSID. For this situation, the AP may monitor the number of probe-requests received by its 2.4G Radio from the STA within a certain time, for example, 4 probe-request messages are received within 5 seconds, which indicates that the STA cannot connect to the 5G SSID, and in order to avoid the situation that one SSID of the STA cannot connect to the SSID, if the AP finds the above situation, the AP may access the STA to the 2.4G SSID.
The prior art has an effect on a single AP scene, but has a poor use effect on an application scene in which a plurality of APs use the same SSID for coverage. The number of times that the STA tries to connect is limited, for example, if 5 APs fail to connect repeatedly, the current wireless network is considered to be problematic, so the STA does not try to associate any more, and the user cannot surf the internet. However, since each AP works independently and does not know the status of each AP, the STA only connects 1 time to each AP, but fails to connect to the same SSID 5 times to each STA.
Therefore, how to solve the problem of terminal connection failure in multi-AP service is a problem that needs to be solved by those skilled in the art.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Next, a method for configuring 5G-preferred access based on multiple APs according to an embodiment of the present invention is described in detail. Fig. 1 is a flowchart of a 5G preferred access configuration method based on multiple APs according to an embodiment of the present invention, where the method includes:
s101: and receiving a connection request transmitted by the terminal.
Each AP processes the connection request transmitted by the terminal in the same manner, and in the embodiment of the present invention, an example of one AP is described.
When the terminal needs to connect to the network, the terminal sends a connection request, namely a probe-request, to the AP to which the terminal belongs.
S102: and when the local application is set with 5G priority and the connection request is 2.4G connection, judging whether the terminal in the database supports dual-frequency.
In the embodiment of the invention, the same terminal may send the connection request to a plurality of APs under the same SSID, in order to realize the data sharing among the APs, a database which is convenient for the plurality of APs to access together can be established, each AP can record the condition that the terminal sends the connection request in the database, and the AP can acquire the information such as the connection times of the terminal by inquiring the database.
The database may employ a Key-Value (Key-Value) storage database. Key-value store databases typically employ a hash table having a particular key and a pointer to particular data. The Key/value model has the advantages of simplicity and easy deployment for IT systems. Types of key-value store databases include Redis or Memorycache, among others.
The dual-band support means that the terminal supports both 2.4G and 5G bands.
In the initial state, the AP may determine whether the terminal supports dual-band according to the type of the connection request sent by the terminal. By recording whether the terminal supports dual-frequency or not in the database, other APs can know whether the terminal supports dual-frequency or not by inquiring the database, and the judgment is not needed to be carried out according to the type of the connection request sent by the terminal.
When the AP receives the connection request, it may determine whether the 5G-first function is currently enabled according to the configuration. When the AP sets 5G priority and the terminal sends a 2.4G connection, the AP may query the database to know whether the terminal supports dual-band. When the terminal supports dual-band, executing S103; when the terminal does not support dual band, S105 is performed.
S103: and judging whether the rejected times of the terminal in the database within the preset time reach a preset upper limit value or not.
After a terminal sends a connection request to an AP and is rejected, the terminal sends a connection request to other APs under the SSID, and when the terminal sends the connection request for multiple times and is rejected, the terminal stops sending the connection request, thereby causing the connection failure of the terminal. The number of times that the terminal is rejected is recorded in the database, and each time the AP rejects the connection request of the terminal, the number of times that the terminal is rejected is increased by one in the database.
Therefore, in the embodiment of the present invention, when the AP receives the connection request from the terminal, the current AP may query the number of times that the terminal is rejected within the preset time in the data, because the current AP does not know whether the terminal has already sent the connection request to another AP.
The value of the preset time may be set according to a time span when the terminal continuously sends the connection request for multiple times, which is not limited herein.
When the number of times that the terminal is rejected within the preset time does not reach the preset upper limit, it indicates that the subsequent terminal still sends a connection request, and in order to implement that the terminal can preferentially connect to 5G, the AP may perform S104 at this time.
When the number of times that the terminal is rejected within the preset time reaches the preset upper limit, it indicates that the terminal does not send a connection request to the AP for this time, and in order to ensure that the terminal can implement connection with the AP, the AP may perform S105.
S104: and sending a rejection message to the terminal, and adding one to the rejected times of the terminal in the database.
The AP may send a rejected probe response to the terminal because busy indicates that the current SSID is too busy to access. In practical application, the AP may not respond to the connection request of the terminal, so that the terminal cannot find the SSID of 2.4G.
When the AP rejects the connection request of the terminal, in order to facilitate other APs to know the number of times that the terminal sends the connection request, the number of times that the terminal is rejected, which is recorded in the database, needs to be increased by one.
S105: and sending a reply message to the terminal so as to facilitate the terminal to access the wireless local area network.
When the AP allows the terminal to access, the AP sends a reply message, namely a probe-response, to the terminal, and at the moment, the terminal can realize the connection with the AP according to the reply message replied by the AP.
In practical applications, for a terminal supporting dual-band, the first connection request sent by the terminal is often a 2.4G connection, and after the terminal is rejected several times, the terminal may send a 5G connection to the AP. Therefore, when the local application is set with 5G priority and the connection request is 5G connection, the AP sends a reply message to the terminal, so that the terminal can access the wireless local area network.
If the local application does not set the 5G priority, and the AP receives a connection request sent by the terminal, the AP directly sends a reply message to the terminal, so that the terminal can access the wireless local area network conveniently.
According to the technical scheme, the connection request transmitted by the terminal is received; when the local application is set with 5G priority and the connection request is 2.4G connection, judging whether the terminal in the database supports dual-frequency; and when the terminal does not support the dual-frequency, sending a reply message to the terminal so as to facilitate the terminal to access the wireless local area network. When the terminal supports double frequency, judging whether the rejected times of the terminal in the database within the preset time reach a preset upper limit value or not; and when the rejected times of the terminal do not reach the preset upper limit value, in order to enable the terminal to be preferentially connected with 5G, sending a rejection message to the terminal, and adding one to the rejected times of the terminal in the database. When the number of times that the terminal is rejected reaches a preset upper limit value, in order to ensure the effective connection of the terminal, a reply message is sent to the terminal, so that the terminal can access the wireless local area network conveniently. In the technical scheme, each AP can acquire the connection times of the terminal which is executed currently according to the times of refusing the terminal recorded in the database, so that the connection between the terminal and the AP is realized when the terminal reaches the upper limit value of the connection times, and the problem of connection failure of the terminal during multi-AP service is solved while the 5G priority connection is ensured.
Considering that when the terminal is rejected by the current AP, the terminal may send a connection request to another AP, and a time interval for the terminal to send the connection request multiple times is not too long, in order to reduce interference between two unrelated connection requests, in this embodiment of the present invention, an effective time may be set for the number of times the terminal is rejected. Specifically, when the number of times that the terminal is rejected in the database is added for the first time, timing is started; and when the timing time reaches the preset time, clearing the rejected times of the terminal. And after the rejected times of the terminal are cleared, the terminal starts to count again when sending the connection request again.
The rejected times of the terminal are limited in time, so that statistics can be carried out only on the rejected times when the terminal sends the connection request currently, and interference of non-related connection requests is avoided.
In practical applications, it may happen that the terminal always sends a 2.4G connection request, so that the terminal realizes a 2.4G connection with the AP only when the number of times that the terminal is rejected within a preset time reaches a preset upper limit value. For such a situation, in order to improve the processing efficiency of the AP and reduce the useless judgment of the AP, the connection situation of the terminal may be evaluated many times.
In the embodiment of the present invention, for a terminal supporting dual-band, the number of times that the terminal realizes 2.4G connection with an AP only when the number of times that the terminal is rejected in a preset time reaches a preset upper limit value may be counted, and the number of times may be referred to as a number of times of handover. When the number of times that the terminal is rejected reaches a preset upper limit value, after the AP sends a reply message to the terminal for 2.4G connection with the terminal, the number of times of switching of the terminal in the database needs to be increased by one.
Before determining whether the terminal in the database supports dual-band, the AP may first determine whether the number of times of switching of the terminal in the database reaches a switching threshold.
The value of the switching threshold may be set according to actual requirements, and is not limited herein.
And when the switching times of the terminal do not reach the switching threshold value, executing a step of judging whether the terminal supports dual-frequency in the database.
When the switching times of the terminal reach the switching threshold value, the terminal is indicated to have continuously connected with the 2.4G frequency band for many times, even if the AP rejects the current connection request of the terminal, when the rejected times of the terminal in the preset time reach the preset upper limit value, the terminal still sends the 2.4G connection request to the AP. In order to improve the processing efficiency of the AP, when the number of times of switching of the terminal reaches the switching threshold, the AP may directly send a reply message to the terminal, so that the terminal can access the wireless local area network.
By detecting the switching times of the terminal, under the condition that the terminal realizes the 2.4G connection with the AP only when the times of rejecting the terminal within the preset time reaches the preset upper limit value for many times, if the terminal still sends a 2.4G connection request to the AP, the AP directly sends a reply message to the terminal, the connection request of the terminal does not need to be rejected for many times, and the processing efficiency of the AP is improved.
In the embodiment of the present invention, in order to avoid the situation that the terminal can only connect to the 2.4G frequency band for a long time due to the limitation of the handover threshold, an effective time may be set for the number of handovers. Specifically, when the switching frequency of the terminal reaches a switching threshold value, setting effective time; and when receiving the 2.4G connection request sent by the terminal within the effective time, sending a reply message to the terminal so as to facilitate the terminal to access the wireless local area network. When the valid time is over, the connection request of the terminal is processed again according to the flow shown in fig. 1.
When the valid time is over, a new round of statistics can be performed, and at this time, the switching times of the terminal can be cleared, so that the switching times of the terminal can be counted again.
By setting the effective time, the processing efficiency of the AP on the terminal connection request is improved, and the situation that the terminal can only be connected with the 2.4G frequency band when the switching times of the terminal reach the switching threshold value is avoided.
In the embodiment of the present invention, the information of the terminal may be recorded in a key value storage database, and as shown in table 1, the terminal list includes 3 key value pairs.
TABLE 1
In a specific implementation, as to whether the terminal supports 5G, a "0" may be used to indicate that the terminal does not support 5G, and a "1" may be used to indicate that the terminal supports 5G.
In table 1, whether the terminal supports 5G is recorded in the form of a 5G MAC table. The timeout time is used to indicate the valid time of various types of information, taking a 5G MAC table as an example, when the AP determines whether the terminal supports 5G, the information is recorded in the 5G MAC table, at this time, timing is started, when the timing time reaches 1 day, the recording is cleared, and whether the terminal supports 5G is determined again. The validity of the information recorded in the key-value storage database can be guaranteed by setting the timeout time.
And when the 3 key value pairs are all on-line, each AP independently reads the operation to be taken next, and simultaneously writes the new state into the key value storage database. Because each AP writes in and reads the same key value storage database, and simultaneously takes the MAC of the terminal as a key word, the AP can automatically acquire the value of the current terminal at other APs.
