Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Firstly, describing an application scenario of the present disclosure, the present disclosure is applied to a scenario in which access point devices such as routers and terminal devices of users are wirelessly connected, and aggregation and collaboration of multiple frequency bands of the access point in the scenario can be achieved, that is, the access point devices and the terminal devices can communicate in two frequency bands such as 2.4GHz, 5.2GHz and 5.8GHz at the same time; for example, the access point device and the terminal device may communicate over two frequency bands, 2.4GHz and 5.2GHz simultaneously; for another example, the access point device and the terminal device may communicate through two frequency bands, 2.4GHz and 5.8GHz simultaneously; for another example, the access point device and the terminal device may communicate over both the 5.2GHz and 5.8GHz frequency bands.
Currently, in order to improve the wireless transmission rate between an access point device and a terminal device, when a communication frequency band between the access point device and the terminal device is switched, the communication frequency band between the access point device and the terminal device is mainly switched from one frequency band to another frequency band, for example, from a 2.4GHz frequency band to a 5.8GHz frequency band, so as to attempt to improve the wireless transmission rate of the terminal device.
However, as the access point device and the terminal device can communicate through multiple frequency bands of 2.4GHz, 5.2GHz, 5.8GHz, and the like, it is no longer suitable to switch the communication frequency band between the access point device and the terminal device from one frequency band to another frequency band of the multiple frequency bands, on the other hand, due to the transmission rate between the access point device and the terminal device, the wireless transmission rate between the access point device and the terminal device may not be effectively improved if the communication frequency band between the access point device and the terminal device is directly switched to the frequency band with the higher maximum bandwidth.
In order to overcome the technical problems, the present disclosure provides a method, an apparatus, a device and a storage medium for connection control.
Fig. 1 is a flowchart illustrating a method of connection control for an access point device, as shown in fig. 1, according to an exemplary embodiment, comprising the steps of:
in step S11, determining a first frequency band combining mode of the current working of the terminal device; the frequency band combination mode comprises at least two frequency bands.
The first frequency band combination mode of the current working of the terminal equipment can be, for example, a frequency band combination of 2.4GHz and 5.8GHz, the terminal equipment communicates with the access point equipment through at least two frequency bands in the first frequency band combination mode, so that the maximum bandwidth supported by the terminal equipment can be improved, for example, the maximum bandwidth of the 2.4GHz frequency band is 40MHz, the maximum bandwidth of the 5.8GHz frequency band is 80MHz, the communication is performed between the terminal equipment and the access point equipment through the frequency band combination of 2.4GHz and 5.8GHz, and the maximum bandwidth supported by the terminal equipment can reach 40MHz+80 MHz=120 MHz.
The Access Point device may include a plurality of APs (Access points), the terminal device may include a plurality of STAs (stations), and the number of APs included in the Access Point device and the number of STAs included in the terminal device in the embodiments of the present disclosure are not limited.
For example, an access point device may include AP1, AP2, and AP3, with different APs operating in different frequency bands; the terminal equipment comprises an STA1, an STA2 and an STA3, wherein different STAs work in different frequency bands; the AP1 of the access point device and the STA1 of the terminal device may communicate in the 2.4GHz band, the AP2 of the access point device and the STA2 of the terminal device may communicate in the 5.2GHz band, and the AP3 of the access point device and the STA3 of the terminal device may communicate in the 5.8GHz band.
The access point device can determine the frequency band of the terminal device currently communicating with the access point device according to the received Beacon message or other messages from the terminal device, thereby determining the first frequency band combination mode of the current working of the terminal device, and providing a reference for whether to switch the current working frequency band combination mode of the terminal device.
In step S12, determining a second frequency band combining mode corresponding to the terminal device; the second frequency band combination mode is a frequency band combination mode supported by the terminal equipment, and the second frequency band combination mode is different from the first frequency band combination mode.
The frequency band combination mode supported by the terminal equipment can comprise, for example: 2.4GHz and 5.2GHz, 2.4GHz and 5.8GHz, and 5.2GHz and 5.8GHz, or, a part of terminal devices may not support 5.2GHz and 5.8GHz, where the terminal devices do not support 5.2GHz and 5.8GHz, the manner of frequency band combination supported by the terminal devices may include: 2.4GHz and 5.2GHz, and 2.4GHz and 5.8 GHz.
A second frequency band combination mode can be determined from frequency band combination modes except the first frequency band combination mode in the frequency band combination modes supported by the terminal equipment; for example, if the terminal device supports three frequency band combination modes, i.e., a frequency band combination of 2.4GHz and 5.2GHz, a frequency band combination of 2.4GHz and 5.8GHz, and a frequency band combination of 5.2GHz and 5.8GHz, the second frequency band combination mode may be a frequency band combination of 2.4GHz and 5.2GHz, or the second frequency band combination mode may be a frequency band combination of 5.2GHz and 5.8GHz when the first frequency band combination mode currently operated by the terminal device is a frequency band combination of 2.4GHz and 5.8 GHz.
In one embodiment, determining the second frequency band combining mode corresponding to the terminal device includes: determining a bandwidth corresponding to a frequency band combination mode supported by terminal equipment; and determining a second frequency band combination mode corresponding to the terminal equipment from the frequency band combination modes supported by the terminal equipment under the condition that the bandwidth of the first frequency band combination mode is not the maximum bandwidth.
For example, from the frequency band combination modes supported by the terminal device, determining the second frequency band combination mode corresponding to the terminal device includes: determining one or more third frequency band combination modes from frequency band combination modes supported by the terminal equipment, wherein the one or more third frequency band combination modes are other frequency band combination modes except the first frequency band combination mode in the frequency band combination modes supported by the terminal equipment; and taking the frequency band combination mode with the largest bandwidth in the one or more third frequency band combination modes as a second frequency band combination mode.
In this way, when the bandwidth of the first frequency band combination mode is not the maximum bandwidth, the second frequency band combination mode corresponding to the terminal device is determined from the frequency band combination modes supported by the terminal device, so that the bandwidth of the second frequency band combination mode is higher, the terminal device can obtain higher maximum bandwidth, and the upper limit of the wireless transmission rate of the terminal device is improved.
In step S13, a first data transmission rate of the terminal device with the access point device in the first frequency band combining manner and a second data transmission rate of the terminal device with the access point device in the second frequency band combining manner are obtained.
In one embodiment, obtaining a first data transmission rate of the terminal device with the access point device in the first frequency band combining manner, and obtaining a second data transmission rate of the terminal device with the access point device in the second frequency band combining manner includes: taking the sum value of the data transmission rate of the terminal equipment and the access point equipment in each frequency band in the first frequency band combination mode as a first data transmission rate; and taking the sum value of the data transmission rate of the terminal equipment and the access point equipment in each frequency band in the second frequency band combination mode as a second data transmission rate.
For example, in the case where the terminal device and the access point device are connected in dual frequencies of the first frequency band and the second frequency band, the first frequency band combination mode is a frequency band combination of the first frequency band and the second frequency band, the terminal device may perform data transmission with the access point device through the first frequency band and the second frequency band at the same time, if the data transmission rate of the terminal device and the access point device in the first frequency band is a, and the data transmission rate of the terminal device and the access point device in the second frequency band is B, the first data transmission rate of the terminal device and the access point device in the first frequency band combination mode is a+b. The first frequency band and the second frequency band are frequency bands supported by the terminal equipment, and the frequency band combination of the first frequency band and the second frequency band is a frequency band combination mode supported by the terminal equipment.
If the second frequency band combination mode is a frequency band combination of a third frequency band and a fourth frequency band, the data transmission rate of the terminal equipment and the access point equipment is C under the third frequency band, and the data transmission rate of the terminal equipment and the access point equipment is D under the fourth frequency band, the second data transmission rate of the terminal equipment and the access point equipment is C+D under the second frequency band combination mode; the third frequency band and the fourth frequency band are frequency bands supported by the terminal equipment, and the frequency band combination of the third frequency band and the fourth frequency band is a frequency band combination mode supported by the terminal equipment.
The first frequency band, the second frequency band, the third frequency band and the fourth frequency band can be different frequency bands; or, the first frequency band, the second frequency band, the third frequency band and the fourth frequency band may also have the same frequency band, for example, the second frequency band and the third frequency band may be the same frequency band, and in this embodiment, it is not limited whether the first frequency band combination mode and the second frequency band combination mode include one or more identical frequency bands, and the first frequency band combination mode and the second frequency band combination mode may be different frequency band combination modes.
The method comprises the steps of acquiring a first data transmission rate of the terminal equipment and the access point equipment in a first frequency band combination mode and a second data transmission rate of the terminal equipment and the access point equipment in a second frequency band combination mode, and switching the current working frequency band combination mode of the terminal equipment according to the first data transmission rate and the second data transmission rate, so that the wireless transmission rate of the terminal equipment is improved.
In step S14, the current operating frequency band combination mode of the terminal device is switched from the first frequency band combination mode to the second frequency band combination mode according to the first data transmission rate and the second data transmission rate.
In one possible implementation manner, according to the first data transmission rate and the second data transmission rate, switching the current operating frequency band combination mode of the terminal device from the first frequency band combination mode to the second frequency band combination mode includes: and under the condition that the second data transmission rate is larger than the first data transmission rate, switching the current working frequency band combination mode of the terminal equipment from the first frequency band combination mode to the second frequency band combination mode.
For example, the first data transmission rate of the terminal device and the access point device in the first frequency band combination mode is a+b, the second data transmission rate of the terminal device and the access point device in the second frequency band combination mode is c+d, and (c+d) > (a+b), which indicates that the terminal device can obtain a higher data transmission rate than in the first frequency band combination mode in the second frequency band combination mode, and the current working frequency band combination mode of the terminal device can be switched from the first frequency band combination mode to the second frequency band combination mode, so as to improve the data transmission rate between the terminal device and the access point device.
The switching the current working frequency band combination mode of the terminal device from the first frequency band combination mode to the second frequency band combination mode may include, for example: the access point device sends a working frequency band combination mode switching request to the terminal device, wherein the working frequency band combination mode switching request carries at least two frequency bands included in the second frequency band combination mode.
For example, the access point device may send a Link Reconfiguration Notify packet to the terminal device, where the Link Reconfiguration Notify packet includes deleted frequency band information and added frequency band information, for example, when the frequency band combination mode of 2.4GHz and 5.8GHz is switched to the frequency band combination mode of 2.4GHz and 5.2GHz, the 5.8GHz frequency band is the deleted frequency band information, and the 5.2GHz frequency band is the added frequency band information, where in the embodiment of the present application, the packet format sent by the access point device to the terminal device is not limited when the working frequency band combination mode is switched.
In another embodiment, when the second data transmission rate is less than or equal to the first data transmission rate, the current operating frequency band combination mode of the terminal device is kept to be the first frequency band combination mode.
The second data transmission rate is smaller than or equal to the first data transmission rate, which means that if the current working frequency band combination mode of the terminal equipment is switched to the second frequency band combination mode, the data transmission rate between the terminal equipment and the access point equipment is lower than the current data transmission rate, which is not beneficial to ensuring the data transmission rate between the terminal equipment and the access point equipment; and under the condition that the second data transmission rate is smaller than or equal to the first data transmission rate, the current working frequency band combination mode of the terminal equipment is kept to be the first frequency band combination mode, so that the data transmission rate between the terminal equipment and the access point equipment is guaranteed.
In one embodiment, the data transmission rate of the terminal device with the access point device in each frequency band may be determined by: transmitting a measurement request for requesting measurement of the strength of the connection signal to the terminal device; the receiving terminal equipment sends a measurement report based on the measurement request, wherein the measurement report carries the received channel power indication RCPI of each frequency band; and determining the data transmission rate of the terminal equipment and the access point equipment under each frequency band according to the RCPI of each frequency band.
The data transmission rate of the terminal equipment and the access point equipment in each frequency band can be determined by receiving a test report which is sent by the terminal equipment and carries RCPI (Received Channel Power Indicator and received channel power indication), so that the method is helpful for determining whether to switch the current working frequency band combination mode of the terminal equipment; the content of the data transmission rate between the terminal device and the access point device in each frequency band is determined according to the RCPI of each frequency band, and the embodiments of the present application will not be described in detail.
In one embodiment, before performing step S11, it may also be determined that all access points of the access point device are in an operating state.
For example, the access point device may support 2.4GHz, 5.2GHz, and 5.8GHz, where the maximum bandwidth of the 5.2GHz band may reach 160MHz, but the access point device may perform DFS (Dynamic Frequency Selection ) before using the 5.2GHz band, where DFS refers to allowing unlicensed devices to share the 5GHz band allocated to the radar system to avoid interference of these 5GHz bands allocated to the radar system with the access point device; for example, the DFS may detect channels 52, 56, 60, 64, etc. for a preset period of time, for example, 1 minute, to avoid the influence of the access point device on the 5.2GHz band when the channels are allocated to the radar system, where the access point device is temporarily unable to communicate with the terminal device in the 5.2GHz band during the DFS.
By determining that all access points of the access point device are in a working state, the terminal device can perform data transmission with the access point device in a frequency band combination mode with larger bandwidth in the supported frequency band combination modes as much as possible, and the terminal device can obtain higher data transmission rate.
For example, if the three frequency bands of 2.4GHz, 5.2GHz and 5.8GHz of the access point device are all in an operating state, when the terminal device and the access point device perform data transmission in the frequency band combining manner of 2.4GHz and 5.8GHz, and when the current operating frequency band combining manner of the terminal device is switched, the current operating frequency band combining manner of the terminal device can be switched to the frequency band combining manner of 2.4GHz and 5.2GHz, so that the maximum bandwidth of 40mhz+80mhz=120 MHz before switching can be switched to the maximum bandwidth of 40mhz+160mhz=200 MHz.
Thus, under the condition of completing DFS, the switching from the frequency band combination mode of 2.4GHz and 5.8GHz to the frequency band combination mode of 2.4GHz and 5.2GHz can be realized; or under the condition that the terminal equipment supports the frequency band combination mode of 5.2GHz and 5.8GHz, the switching from the frequency band combination mode of 2.4GHz and 5.8GHz to the frequency band combination mode of 5.2GHz and 5.8GHz can be realized, and the maximum bandwidth of data transmission between the terminal equipment and the access point equipment is improved.
In another embodiment, in the case that the current operating frequency band combination mode is the frequency band combination mode with the largest bandwidth among the frequency band combination modes supported by the terminal device, the switching of the current operating frequency band combination mode is not performed any more, so that the maximum bandwidth supported by the terminal device is reached between the terminal device and the access point device, which means that the data transmission rate between the terminal device and the access point device has a high probability of meeting the use requirement of the user, and the operation power consumption of the access point device or the terminal device can be reduced.
According to the connection control method provided by the disclosure, according to the first data transmission rate corresponding to the first frequency band combination mode of the current operation of the terminal equipment and the second data transmission rate corresponding to the second frequency band combination mode, the current operation frequency band combination mode of the terminal equipment can be switched from the first frequency band combination mode to the second frequency band combination mode.
Fig. 2 is a flowchart illustrating a method of connection control according to an exemplary embodiment, and as shown in fig. 2, a frequency band combination manner supported by a terminal device may be determined by:
step S21, a message frame is sent to the terminal equipment, and the message frame is used for indicating the terminal equipment to send feedback message frames based on the message frame in a mode of combining a plurality of frequency bands.
The message frame sent by the access point device to the terminal device may be, for example, a Beacon Request measurement Request sent by the access point device to the terminal device, where the message frame is used to instruct the terminal device to send feedback message frames based on the message frame by using a mode of combining multiple frequency bands.
The feedback message frame sent by the terminal device based on the message frame may be, for example, a Beacon message carrying AP information sent by the terminal device to the access point device when the terminal device receives a Beacon Request measurement Request sent by the access point device to the terminal device, for example, the terminal device may determine that the terminal device sends the AP information to the access point device through two frequency bands of 2.4GHz and 5.2GHz according to the Beacon message carrying the AP information.
In one embodiment, transmitting a message frame to a terminal device includes: acquiring traffic usage information of terminal equipment; and sending a message frame to the terminal equipment in the condition that the network of the terminal equipment is determined to be in an idle state according to the traffic usage information.
For example, the access point device may send a test request to the terminal device, determine traffic usage information of the terminal device according to a received test report based on the test request sent by the terminal device, and determine whether a network of the terminal device is in an idle state according to the traffic usage information.
Under the condition that the network of the terminal equipment is in an idle state according to the traffic use information, the message frame is sent to the terminal equipment, so that the influence of the message frame sent to the terminal equipment on the user network can be reduced, and the use experience of the user is prevented from being reduced.
In another embodiment, transmitting the message frame to the terminal device includes: determining a received signal strength indication, RSSI, (Received Signal Strength Indication ) between the access point device and the terminal device; and sending the message frame to the terminal equipment under the condition that the RSSI is greater than or equal to a preset signal strength threshold value. The preset signal strength threshold can be set according to actual requirements.
Therefore, the RSSI is larger than or equal to a preset signal strength threshold, and the wireless connection condition between the access point equipment and the terminal equipment is good, so that the use of the terminal equipment by a user is not affected when a message frame is sent to the terminal equipment; meanwhile, if the current working frequency band combination mode of the terminal equipment is switched subsequently under the condition that the RSSI is larger than or equal to the preset signal strength threshold, the access point equipment and the terminal equipment still have better wireless connection condition with larger probability in the switched frequency band combination mode, and the data transmission rate of the terminal equipment is improved.
Step S22, receiving a feedback message frame sent by the terminal equipment in a mode of combining a plurality of preset frequency bands.
For example, in the case where the access point device has transmitted a message frame to the terminal device, the access point device may receive AP information from the terminal device at both 2.4GHz and 5.2GHz frequency bands.
Step S23, determining a frequency band combination mode supported by the terminal equipment according to the received feedback message frame.
In one possible implementation manner, determining, according to the received feedback message frame, a frequency band combination manner supported by the terminal device includes: and under the condition that the feedback message frame is received, taking a preset frequency band combination mode corresponding to the feedback message frame as a frequency band combination mode supported by the terminal equipment.
For example, in the case that the access point device has sent a message frame to the terminal device, the access point device may receive AP information from the terminal device in two frequency bands of 2.4GHz and 5.2GHz at the same time, and then determine that the terminal device supports a frequency band combination manner including the 2.4GHz frequency band and the 5.2GHz frequency band, and thus determine other frequency band combination manners supported by the terminal device respectively.
In one embodiment, the frequency band combination manner supported by the terminal device may also be determined by the following manner: according to the history connection record of the access point equipment and the terminal equipment, determining a history frequency band combination mode of the history connection of the terminal equipment; and using the historical frequency band combination mode as a frequency band combination mode supported by the terminal equipment.
For example, according to the history connection record of the access point device and the terminal device, the terminal device and the access point device perform data transmission in a frequency band combination mode of the 5.2GHz frequency band and the 5.8GHz frequency band, which indicates that the terminal device has the capability of performing data transmission in a frequency band combination mode of the 5.2GHz frequency band and the 5.8GHz frequency band.
In this way, the historical frequency band combination mode is used as the frequency band combination mode supported by the terminal equipment, and the frequency band combination mode supported by the terminal equipment is not required to be determined by sending a message frame to the terminal equipment and according to the feedback message frame, so that the frequency band combination mode supported by the terminal equipment can be rapidly determined, and the operation power consumption of the access point equipment and the terminal equipment can be reduced.
