Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
With the development of communication technology, wireless Access points (Access points) are becoming visible everywhere, and almost all smartphones, tablet computers and notebook computers support Access to the network through the wireless Access points. The wireless communication technology used by the relevant wireless access node may include collision detection.
Take WiFi communication as an example. In the WiFi communication mode, a CSMA/CA mechanism is configured. Among the main workflows based on the CSMA/CA (Carrier Sense Multiple Access with Collision Avoid) mechanism are: when the electronic device needs to transmit a data frame, it first detects the channel and after continuously detecting that the channel is idle for one DIFS (Distributed Inter-frame Spacing), it transmits the data frame. The wireless access point correctly receives the data frame and immediately sends out an acknowledgement for the data frame after waiting for one SIFS (Short interframe space). If the electronic device does not receive the acknowledgement frame ACK within a specified time, it must retransmit the frame until an acknowledgement is received, or discard the transmission after several retransmission failures. Then, under the limitation of the CSMA/CA mechanism, an electronic device accessing the WiFi network listens to the channel before sending the traffic, and selects to backoff for a random period of time once it finds that there is data transmission on the channel.
With the development of WiFi communication, in WiFi6 (original name: 802.11. Ax), the concept of BSS Color is introduced, that is, each wireless access point is equipped with a BSS Color with a length of 6 bits. In this case, the electronic device selects back-off only when the BSS Color carried in the transmitted data packet is the same as the BSS Color of the electronic device to which it has access when listening to the channel, otherwise, it can transmit by itself. In further research, the inventor found that, although collision of electronic devices transmitting services under different electronic devices is reduced in this case, collision under the same BSS Color is still serious for a wireless access point with a large traffic volume, which simultaneously serves a plurality of electronic devices.
Accordingly, the inventors propose a wireless communication method, apparatus, electronic device, and storage medium in the present application. After the electronic equipment initially negotiates the corresponding working time periods with the plurality of wireless access points, the working time periods of the plurality of wireless access points corresponding to the electronic equipment can be dynamically updated in real time according to the communication state detected by the electronic equipment and corresponding to each wireless access point, and the flexibility of the electronic equipment in the communication process is improved.
An operating environment for embodiments of the present application is described below with reference to the accompanying drawings.
The operating environment shown in fig. 1 includes an electronic device 100, a wireless access point 111, and a wireless access point 112.
The wireless access point 111 transmits wireless signals, and the wireless access point 112 also transmits wireless signals. Wherein the wireless access point 111 and the dotted circle surrounding the wireless access point 112 characterize the respective wireless signal coverage. The electronic device 110 may be illustrated as being within the coverage of both the wireless signals transmitted by the wireless access point 111 and the wireless signals transmitted by the wireless access point 112. In this way, the electronic device 110 may access the network through both the first wireless access point 111 and the wireless access point 112.
It should be noted that, in the embodiment of the present application, the number of the included wireless access points is not limited to the number shown in the figure, and more wireless access points may be included. Correspondingly, for the same wireless access point, more wireless access devices can be accessed simultaneously.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, a wireless communication method provided by an embodiment of the present application is applied to an electronic device, and the method includes:
Step S110: and acquiring a plurality of wireless access points in a wireless scanning mode.
It will be appreciated that the wireless signals transmitted by the wireless access points are all of a range of coverage. And when the electronic equipment is in the coverage range of the wireless signal transmitted by the wireless access point, the electronic equipment can receive the wireless signal transmitted by the wireless access point. Then, as one way, the electronic device may scan the target frequency band at a certain frequency after the wireless access function is started, and if the target signal can be scanned in the target frequency band, then determine that the wireless access point is scanned. It should be noted that, the target signal is a wireless signal transmitted by the wireless access point based on the target wireless communication protocol. The electronic device scans the designated frequency band for a wireless signal transmitted based on the target wireless communication protocol after the wireless access function is turned on, and if so, determines that the target signal is scanned.
Alternatively, the target protocol may be a WiFi communication protocol, or may be another wireless communication protocol, for example, a bluetooth protocol, etc.
Then the plurality of wireless access points can be obtained by the scanning method when the electronic device is within the coverage range of the plurality of wireless access points.
Step S120: and determining that the plurality of wireless access points respectively correspond to the working time periods of the electronic equipment, wherein the electronic equipment communicates with the wireless access point matched with the current moment by accessing the corresponding working time periods.
In an embodiment, the electronic device may not always communicate through one wireless access point, but may switch between multiple wireless access points, i.e., communicate through one wireless access point for a certain period of time and communicate through another wireless access point for another period of time. Then, in order to implement the foregoing handoff prior to the plurality of wireless access points, as one way, the electronic device may negotiate with the plurality of wireless access points to determine that the plurality of wireless access points respectively correspond to the operating time periods of the electronic device when scanning for the plurality of wireless access points. For example, it may be determined that the plurality of wireless access points respectively correspond to the operating Time periods of the electronic device based on a Target Wake Time (Target Wake Time). In this way, the electronic device may detect the current time in real time, and further use the wireless access point with the corresponding working period matching the current time as the wireless access point used for current communication.
It should be noted that, the matching of the corresponding working period with the current time may be understood that the current time falls within the coverage range of the working period. For example, if a certain working period is from 2 points to 3 points, if the current time is 1:45, it can be understood that the current time is not matched with the certain working period when the electronic device detects that the current time is 1:45, and the current time does not reach 2 points yet. If the current time is 2:45, it can be understood that the electronic device determines that the current time matches the certain working period when detecting that the current time is 2:45.
For example, referring to fig. 3, fig. 3 shows an electronic device negotiating a certain period of operation with a scanned wireless access point AP0 and a wireless access point AP 1. The shaded portion in the period corresponding to AP0 is a period in which the wireless access point AP0 corresponds to the operating period of the electronic device, and the shaded portion in the period corresponding to AP1 is a period in which the wireless access point AP1 corresponds to the operating period of the electronic device. While the white portion thereof may be understood as wireless access point AP0 and wireless access point AP1 corresponding to the sleep period of the electronic device. In this case, the electronic device may detect that the current time matches the operation period of the wireless access point AP0 in the period of t1 to t2, and then determine that communication is performed by establishing a connection with the wireless access point AP0 in the period of t1 to t 2. Correspondingly, after the time is extended to t2, in the period from t2 to t3, the electronic device detects that the working period matched with the current time is the working period of the AP1, and further, in the period from t2 to t3, the electronic device establishes a connection with the wireless access point AP1 to perform communication.
It should be noted that, in one manner, the operating periods of the plurality of wireless access points corresponding to the electronic devices are completely staggered from each other, and not the operating periods (i.e., the sleep periods) may have portions overlapping each other.
It should be noted that, in this embodiment, the electronic device communicating through the wireless access point may be understood that the electronic device transfers the data that needs to be sent to the destination address to the connected wireless access point, and then forwards the data to the destination address from the wireless access point. And the destination address may point to a server or other terminal in the wide area network or may point to a server or terminal in the local area network.
Step S130: if a target wireless access point is detected in the wireless access points communicating with the electronic equipment, updating the working time periods of the plurality of wireless access points corresponding to the electronic equipment, wherein the target wireless access point is a wireless access point with the corresponding communication state meeting the target condition.
In order to detect the current communication situation in real time, the electronic device may detect the communication state of the connected wireless access point in real time, so as to determine whether the communication state of the connected wireless access point meets the target condition.
As one way, the target condition includes: the collision rate during communication based on the wireless access point is greater than the specified collision rate. In this manner, the step of updating the operating time periods of the electronic device for each of the plurality of wireless access points includes: the length of the working time period of the electronic equipment corresponding to the target wireless access point is shortened, and the length of the working time period of the electronic equipment corresponding to other wireless access points except the target wireless access point is prolonged.
From the foregoing, it can be appreciated that a collision situation may occur in an electronic device during communication through a wireless access point. The electronic device can determine the communication state of the wireless access point through the collision rate in the communication process. It will be appreciated that a greater communication collision rate characterizes a greater probability of requiring data retransmission, meaning that the communication state is not so good. And further, when the collision rate of the connected wireless access point is detected to be larger than the specified collision rate, judging the connected wireless access point as a target wireless access point, further shortening the length of the target wireless access point corresponding to the working time period of the electronic equipment, and correspondingly prolonging the lengths of other wireless access points except the target wireless access point corresponding to the working time period of the electronic equipment.
For example, the electronic device acquires the wireless access point AP0 and the wireless access point AP1 after scanning, and then in the actual communication process, the electronic device detects that the communication state of the wireless access point AP0 meets the condition, so that the length of the wireless access point AP0 corresponding to the working period of the electronic device is further shortened, and the length of the wireless access point AP1 corresponding to the working period of the electronic device is prolonged, so as to shorten the time length of the electronic device connecting the wireless access point AP0 in the communication process. For example, if fig. 3 is a schematic diagram of the initially determined wireless access point AP0 and the wireless access point AP1 each corresponding to an operation period of the electronic device (where a hatched portion is the operation period and a blank portion is the sleep period), and fig. 4 is a diagram of the updated wireless access point AP0 and the wireless access point AP1 each corresponding to the operation period of the electronic device, then the comparison finds that the operation period of AP1 corresponding to the electronic device is prolonged and the operation period of AP0 corresponding to the electronic device is shortened.
While there are a number of ways to determine how much a wireless access point other than the target wireless access point corresponds to the operating period of the electronic device.
In one manner, the number of the other wireless access points than the target wireless access point is one, and the step of extending the length of the operation period corresponding to the other wireless access points than the target wireless access point includes: acquiring working parameters of other wireless access points except the target wireless access point; based on the operating parameters, it is determined that other wireless access points than the target wireless access point correspond to a length of the electronic device extended by an operating period of time.
Wherein the operating parameters include at least one of the following: wireless signal strength of the wireless access point; the number of terminal devices to which the wireless access point is currently connected; and data throughput of the wireless access point.
It should be noted that, it is desirable to have a smoother communication environment in the overall communication process of the electronic device when the electronic device re-updates the plurality of wireless access points corresponding to the operation time period of the electronic device. Correspondingly, if the wireless access points except the target wireless access point have better communication states, more communication time can be allocated appropriately, and a relatively longer working period can be obtained. For the wireless access point, the number of electronic devices currently accessed, the wireless signal strength, and the data throughput of the current wireless access point may affect the smoothness of the communication of the accessed electronic devices.
For example, in the case where there are many electronic devices connected to the wireless access point, the contention of the channel resources by the plurality of electronic devices is more intense, and thus more collisions are caused. In this case, the corresponding length of the corresponding working period is prolonged, so that better communication smoothness may still not be obtained, and instead, time is consumed to redetermine that the plurality of wireless access points correspond to the working period of the electronic device. However, if there are few electronic devices connected to the wireless access point, for example, the wireless access point has only 2 or 3 electronic devices connected thereto, then there is a possibility that many collisions will not occur during communication by the wireless access point. The same is true for both the wireless signal strength of the wireless access point and the data throughput of the wireless access point.
After a plurality of wireless access points are acquired in a wireless scanning manner, the electronic device can further negotiate with the plurality of wireless access points to determine that the plurality of wireless access points respectively correspond to the working time period of the electronic device, wherein after the working time period is determined, the electronic device communicates with the wireless access point matched with the current moment by accessing the corresponding working time period. And in the communication process, if a target wireless access point is detected in the wireless access points which are communicated with the electronic equipment, updating the working time periods of the plurality of wireless access points corresponding to the electronic equipment. Therefore, after the electronic equipment initially negotiates the corresponding working time periods with the plurality of wireless access points, the working time periods of the plurality of wireless access points corresponding to the electronic equipment can be dynamically updated in real time according to the communication state detected by the electronic equipment and corresponding to each wireless access point, and the flexibility of the electronic equipment in the communication process is improved.
Referring to fig. 5, a wireless communication method provided by an embodiment of the present application is applied to an electronic device, and the method includes:
step S210: and acquiring a plurality of wireless access points in a wireless scanning mode.
Step S210: and determining that the plurality of wireless access points respectively correspond to the working time periods of the electronic equipment, wherein the electronic equipment communicates with the wireless access point matched with the current moment by accessing the corresponding working time periods.
It should be noted that, as an aspect, when the wireless access device is in the non-operating period, the wireless access device corresponds to the electronic device being in a dormant state and being in a disconnected state with the electronic device. It should be noted that, the wireless access point may access a plurality of electronic devices within a period of time, and then the wireless access point corresponds to a period of time when one of the electronic devices is in an operating period of time, and corresponds to a period of time when the other electronic device is possibly in a non-operating period of time, that is, the aforementioned sleep period of time, and then is in a sleep state corresponding to the electronic device. Therefore, the wireless access point in this embodiment is in a sleep period or in a sleep state for a certain electronic device.
Step S230: if a target wireless access point is detected in the wireless access points which communicate with the electronic equipment, updating the working time periods of the plurality of wireless access points corresponding to the electronic equipment when the target wireless access point is detected to be switched to the working time period, wherein the target wireless access point is a wireless access point with the corresponding communication state meeting the target condition.
It will be appreciated that in this embodiment the particular wireless access point through which the electronic device communicates at a time is determined based on the time period in which each wireless access point corresponds to the electronic device. Then when the electronic device re-determines that the plurality of wireless access points correspond to the operating time period of the electronic device, the electronic device may immediately communicate based on the new operating time period, and then the communication process currently being performed by the electronic device may be interrupted. For example, the electronic device is currently downloading the target file through the wireless access point AP0, and in the downloading process, the electronic device determines that the wireless access point AP0 is the target wireless access point, and further triggers renegotiation of the working period of the wireless access point AP0 corresponding to the electronic device, so that in this case, when the renegotiated working period may be obtained, the electronic device still is still in the working of downloading the target file through the wireless access point AP0, but, based on the renegotiated working period, the wireless access point AP0 corresponds to the non-working period of the electronic device, so that the electronic device must disconnect from the wireless access point AP0 first, and then, a task terminal for downloading the target file is caused, and if no breakpoint continuous transmission is supported in the downloading process, the electronic device must download the content downloaded based on the wireless access point AP0 before the new connection is re-downloaded.
In order to improve the above-mentioned problem, as one aspect, the step of updating the operation time periods of the plurality of wireless access points, each corresponding to the electronic device, when it is detected that the target wireless access point is switched to the operation time period other than the operation time period includes: when the target wireless access point is detected to be switched to the working time period, acquiring the communication state of the wireless access point which is accessed currently; and if the communication state of the currently accessed wireless access point does not meet the target condition, updating the working time periods of the plurality of wireless access points corresponding to the electronic equipment.
It will be appreciated that when it is detected that the target wireless access point has switched to a period of time other than the operating period, it is indicative that the electronic device has not been connected to the target wireless access point, and in this case, updating the plurality of wireless access points to each correspond to the operating period of the electronic device does not cause an interruption in the task in which the electronic device is communicating.
Wherein optionally, if the communication state of the currently accessed wireless access point does not meet the target condition, the step of updating the lengths of the working time periods of the plurality of wireless access points corresponding to the electronic device respectively includes: if the communication state of the currently accessed wireless access point does not meet the target condition; acquiring a stored communication state of the currently accessed wireless access point in a historical working time period; and if the communication state in the historical working time period does not meet the target condition, updating the working time period of the electronic equipment corresponding to each of the plurality of wireless access points.
In one manner, the electronic device starts communication based on the working period of the wireless access point for which the working period end configuration has been completed after detecting that the wireless access point completes the working period configuration. Alternatively, the electronic device starts communication based on the operating periods of the plurality of wireless access points after detecting that all wireless access points have completed the operating period configuration.
Optionally, if a target wireless access point is detected, the step of updating the working time periods of the plurality of wireless access points corresponding to the electronic device respectively includes: if the target wireless access point is detected, suspending the current communication data transmission; and after updating the working time periods of the wireless access points corresponding to the electronic equipment respectively, recovering the communication data transmission.
It should be noted that, in the embodiment of the present application, the manner of detecting whether the target wireless access point exists by the electronic device may be determined by collision detection for the wireless access point directly connected at present, and may also be directly obtained through sharing information of other devices. As shown in fig. 6, the electronic device 110 and the electronic device 100 are simultaneously in communication within the common coverage area of the wireless access point 111 and the wireless access point 112. In this case, then, the electronic device 110 negotiates the operating time periods of the wireless access point 111 and the wireless access point 112 corresponding to the electronic device 110, and the electronic device 100 negotiates the operating time periods of the wireless access point 111 and the wireless access point 112 corresponding to the electronic device 100.
In this case, the electronic device 100 and the electronic device 110 may share the detected target wireless access point with each other, so that the electronic device 100 and the electronic device 110 may timely learn about the target wireless access point (e.g., the wireless access point 111 and the wireless access point 112 in fig. 6) existing in the plurality of wireless access points even if any wireless access points are not connected. Illustratively, the electronic device 110 is currently communicating through the wireless access point 111, and in this process, the electronic device 110, because it is in a connection state with the wireless access point 111, may directly detect the communication state (e.g., collision rate) of the wireless access point 111, while at the same time, the electronic device 100 may also acquire the communication state of the wireless access point 112 shared by the electronic device 110 through other communication paths. For example, the other communication path may be a communication path directly established between electronic device 100 and electronic device 110 through bluetooth or NFC.
In this way, as a way, the electronic device may obtain, in a case of communicating through one wireless access point, a communication state of another unconnected wireless access point from information shared by other electronic devices through other communication paths. Wherein the other communication paths are communication paths independent of any wireless access point. And the electronic equipment can more timely and effectively acquire the communication states of more wireless access points, so that the working time periods of the plurality of wireless access points corresponding to the electronic equipment can be updated more in real time.
Furthermore, in one approach, as shown in fig. 7, the electronic device may scan for more wireless access points, such as wireless access point 111, wireless access point 112, and wireless access point 113 in fig. 7. Then only wireless access point 111 and wireless access point 112 may be negotiated during the initial wireless hotspot scanning phase of the electronic device, each corresponding to an operational period of electronic device 100, in which case electronic device 100 would only communicate through either wireless access point 111 or wireless access point 112 during the communication process. The electronic device detects that the communication state of the wireless access point 111 or the wireless access point 112 in the process of industrial communication not only meets the specified collision rate, but also far exceeds the specified collision rate, so that the currently adopted wireless access point can be abandoned and a new wireless access point can be adopted. For example, if it is detected that the collision rate of the wireless access point 111 far exceeds the specified collision rate, the electronic device 100 may discard the wireless access point 111 and instead negotiate the operating time period for each of the wireless access point 112 and the wireless access point 113 for the electronic device.
After a plurality of wireless access points are acquired in a wireless scanning manner, the electronic device can further negotiate with the plurality of wireless access points to determine that the plurality of wireless access points respectively correspond to the working time period of the electronic device, wherein after the working time period is determined, the electronic device communicates with the wireless access point matched with the current moment by accessing the corresponding working time period. And in the communication process, if a target wireless access point is detected in the wireless access points which are communicated with the electronic equipment, updating the working time periods of the plurality of wireless access points corresponding to the electronic equipment. Therefore, after the electronic equipment initially negotiates the corresponding working time periods with the plurality of wireless access points, the working time periods of the plurality of wireless access points corresponding to the electronic equipment can be dynamically updated in real time according to the communication state detected by the electronic equipment and corresponding to each wireless access point, and the flexibility of the electronic equipment in the communication process is improved. And moreover, under the condition that the collision rate of the target wireless access point is detected to be larger than the designated collision rate, the working time corresponding to the target wireless access point can be shortened, so that the collision of the electronic equipment in the communication process can be reduced, and the passing smoothness can be improved. Furthermore, in the embodiment of the application, the working time periods of the plurality of wireless access points corresponding to the electronic equipment are started when the target wireless access point is switched to the working time period, so that the influence of the updating working time period on the communication process is reduced.
Referring to fig. 8, a wireless communication method provided by an embodiment of the present application is applied to an electronic device, and the method includes:
step S310: and acquiring a plurality of wireless access points in a wireless scanning mode.
Step S320: and acquiring the characteristic parameters of each of the plurality of wireless access points.
Step S330: and sequentially determining that the plurality of wireless access points respectively correspond to the working time periods of the electronic equipment based on the characteristic parameters, wherein the working time periods respectively corresponding to the plurality of wireless access points are mutually staggered, and the electronic equipment communicates with the wireless access points matched with the current moment by accessing the corresponding working time periods.
As one way, the characteristic parameter includes a wireless signal strength; the step of sequentially determining that the plurality of wireless access points respectively correspond to the working time periods of the electronic equipment based on the characteristic parameters comprises the following steps: and sequentially determining the working time periods of the plurality of wireless access points corresponding to the electronic equipment according to the sequence of the corresponding wireless signal intensity from high to low.
