Detailed Description

In order to make the features and advantages of the present application more comprehensible, embodiments accompanied with figures in the present application are described in detail below, wherein the embodiments are described only in some but not all embodiments of the present application. 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.

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 do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application as detailed in the accompanying claims.

In the description of the present application, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art. Furthermore, in the description of the present application, unless otherwise indicated, "a plurality" means two or more. "and/or" describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate that there are three cases of a alone, a and B together, and B alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

In daily life, there are typically many devices in the same wireless network scenario. When the equipment is started, the equipment usually selects and uses the channel with the best network quality according to a network protocol and related technologies, and when a plurality of equipment is started at the same time, the time for selecting the channels is consistent, and the same working channel is easy to select, so that interference is caused, and the quality transmission performance of the wireless network is reduced, the data is lost and the connection is unstable. For example, in a school scenario, wireless microphones and speakers are configured in each classroom for teaching, and are often turned on at the same time during a class, and under the condition that the number of channels is very limited at present, a situation that a plurality of wireless devices use the same channel often occurs. In view of this, the conventional channel adjustment method manually configures wireless network channels for a plurality of devices, and in the case that there are many devices to be adjusted, the manual setting method has a problem that the adjustment efficiency is low, and it is difficult to ensure the stability of the wireless network.

Therefore, in the channel determining method, if a plurality of devices are started at the same time in the wireless transmission system, random delay is performed when the devices are started, after the delay is finished, wireless channel configuration processing is started based on the channel quality of each channel in the wireless network, working channels are selected, and the time for each device to select the working channels is staggered through the random delay, so that the possibility that the plurality of devices simultaneously select the same channel can be reduced, the efficiency of selecting the working channels by the devices is improved, and the stability of the wireless network is ensured.

In order to more clearly clarify the technical scheme of the present application, the related concepts related to the present application are explained below.

The channel is a channel through which signals are transmitted in a communication system, and is formed by a transmission medium through which signals are transmitted from a transmitting end to a receiving end. According to the IEEE 802.11 protocol, in China, a 2.4GHz Wi-Fi frequency band is divided into 13 overlapped channels, the width of each channel is 22MHz (the width of each channel in the IEEE 802.11g standard and the IEEE 802.11n standard is 20MHz,IEEE 802.10B MHz), and the width of each channel in the 5GHz Wi-Fi frequency band is divided into 13 channels, and the width of each channel is 20MHz.

Signal strength (RECEIVED SIGNAL STRENGTH indication, RSSI) at the time of radio reception is related to the transmit power of the radio module, the design of the radio frequency front end and the gain of the antenna, the unit being that of power, generally expressed in dBm. The smaller the signal strength, the lower the channel occupancy in the channel.

Fig. 1 schematically illustrates an architecture of a wireless communication system according to an embodiment of the present application.

As shown in fig. 1, the wireless transmission system 100 may include at least two transmitting devices 101 and at least two receiving devices 102 (illustrated in fig. 1 as an example in which the wireless transmission system 100 includes three transmitting devices and three receiving devices). Each transmitting device 101 corresponds to a respective receiving device 102. The transmitting device 101 may transmit data to the corresponding receiving device 102 over a wireless network. The transmitting device 101 may be hardware or software. When the transmitting device 101 is hardware, it may be various electronic transmitting devices including, but not limited to, a wireless microphone, a smart watch, a smart phone, a tablet computer, a laptop portable computer, a desktop computer, and the like. When the transmitting device 101 is software, it may be installed in the above-listed electron-emitting device, which may be implemented as a plurality of software or software modules, or may be implemented as a single software or software module, which is not particularly limited herein. The receiving device 102 may be hardware or software. When the receiving device 102 is hardware, it may be a variety of electronic receiving devices including, but not limited to, a wireless sound box, a wireless projector, a wireless handle, a wireless headset, and the like. When the receiving apparatus 102 is software, it may be installed in the above-listed electronic receiving apparatus, which may be implemented as a plurality of software or software modules, or may be implemented as a single software or software module, which is not particularly limited herein.

Specifically, a wireless transmitting module is arranged in the transmitting device, and a wireless receiving module is arranged in the receiving device. The wireless transmitting module and the wireless receiving module can be Wi-Fi modules. The transmitting device may send data to the receiving device via the wireless transmitting module. The receiving device may receive the data through a wireless receiving module. The following embodiments of the present application will be described by taking the transmitting device 101 as a wireless microphone and the receiving device 102 as a wireless speaker. The wireless microphone can be connected to the corresponding wireless sound box through a wireless network, and the collected sound signals are transmitted to the wireless sound box and played through the wireless sound box.

In the embodiment of the application, the wireless microphone can also comprise an audio collector and an encoder besides the wireless transmitting module. The audio collector may collect sound signals. The encoder may encode the acquired sound signal. The wireless transmitting module can transmit the encoded sound signals to the wireless loudspeaker box through a wireless network.

In the embodiment of the application, the wireless sound box can also comprise a decoder and a loudspeaker besides the wireless receiving module. The wireless receiving module can receive the coded sound signals sent by the wireless microphone through a wireless network. The decoder may decode the received sound signal. The speaker may play the decoded sound signal.

It should be understood that the number of transmitting devices and receiving devices in fig. 1 is merely illustrative, and any number of transmitting devices and receiving devices may be used, as desired for implementation.

It should be noted that, the channel determining method provided in the embodiment of the present application may be performed by any transmitting device in the wireless transmission system 100 shown in fig. 1, or may be performed by any receiving device in the wireless transmission system 100 shown in fig. 1.

If the method is executed by the transmitting device, the transmitting device may operate in a hot spot mode after the transmitting device and the corresponding receiving device are powered on. After determining the operating channel, the transmitting device may broadcast on the channel. The receiving device may poll its corresponding transmitting device for broadcast signals on each channel. After the receiving device receives a signal on the operating channel selected by its corresponding transmitting device, wireless communication may be established with the transmitting device. The transmitting device and the receiving device can perform data transmission on the selected working channel.

If the method is executed by the receiving device, the receiving device may operate in the hot spot mode after the transmitting device and the corresponding receiving device are powered on. After determining the operating channel, the receiving device may broadcast on the channel. The transmitting device may poll its corresponding receiving device for broadcast signals on each channel. After a transmitting device receives a signal on an operating channel selected by its corresponding receiving device, wireless communication may be established with the receiving device. The transmitting device and the receiving device can perform data transmission on the selected working channel. Referring to fig. 2, fig. 2 is a flow chart of a channel determining method according to an embodiment of the application. For convenience of description, the execution subject of the embodiment of the present application will be referred to as a target device. As described above, the target device may be any one of the transmitting devices in the wireless transmission system 100 shown in fig. 1, or may be any one of the receiving devices in the wireless transmission system 100 shown in fig. 1.

As shown in fig. 2, the channel determining method at least may include:

S201, responding to a starting instruction, and generating a first random delay time in a preset range.

Wherein the first random delay time is different from a random delay time generated by at least two transmitting devices or at least one other device of the at least two receiving devices except the target device. That is, if the target device is a transmitting device, the first random delay time generated by the target device is different from the random delay time generated by at least one other transmitting device other than the target device in at least two transmitting devices in the wireless transmission system 100. In other words, the first random delay time generated by each transmitting device in the wireless transmission system 100 at power-on is at least partially different, but may also be completely different. Wherein the first random delay time belongs to a preset range. The preset range is, for example, but not limited to, 1 millisecond to 20 milliseconds. That is, the first random delay time is in the range of 1 millisecond to 20 milliseconds.

If the target device is a receiving device, the first random delay time generated by the target device is different from the random delay time generated by at least one other receiving device except the target device in at least two receiving devices in the wireless transmission system 100. In other words, the first random delay time generated by each receiving device in the wireless transmission system 100 at power-on is at least partially different, but may also be completely different.

Specifically, when the target device receives the power-on command, the target device may be powered on in response to the power-on command, generate a random number within a preset range, and take the random number as the first random delay time.

Specifically, the target device can generate a random number in a preset range by using a timer contained in the target device as a random seed, and the random number is used as a first random delay time. The preset range is, for example, 1 to 20 milliseconds. That is, the timer may generate a random number as the first random delay time within a preset range of 1 ms to 20 ms. It is known that the target device maintains a waiting state until the first random delay time has arrived.

S202, after the first random delay time is finished, wireless channel configuration processing is started, and an operating channel is determined.

Specifically, after the first random delay time is over, the target device starts scanning channels in the wireless network, returns various data of the channels, and determines a working channel according to the various data of the channels. The data of the channel includes, but is not limited to, RSSI, packet loss rate, interference level, congestion level, adjacent channel interference, etc.

Specifically, an idle channel may be preferentially selected as the working channel. If no idle channel exists, the channel with the best channel quality is selected as the working channel according to each item of data of each channel.

Specifically, RSSI may be used as an indicator to determine whether a channel is idle. When no signal is transmitted in the channel (i.e. when the channel is idle), the current channel can be indicated as the idle channel when the RSSI is a preset threshold. The preset threshold is, for example, but not limited to, -128dBm. If the RSSI of the channel is larger than the preset threshold, the signal is transmitted in the channel, and the signal strength is stronger as the RSSI value is larger.

Specifically, the operating channel may be preferentially selected among the 5G channels. If the working channel cannot be selected from the 5G channels, the working channel can be selected from the 2.4G channels. In the embodiment of the application, a 5G channel can be used as a first type channel, and a 2.4G channel can be used as a second type channel.

Specifically, after the first random delay is finished, the target device may traverse each channel of the first type in turn, and determine that the channel of the first type of the target is a working channel when the signal strength corresponding to the channel of the first type of the target traversed is equal to a preset threshold. I.e. one free channel is selected from the channels of the first type as the working channel. It can be appreciated that when the target device traverses to the idle channel, the idle channel can be directly used as a working channel, and the remaining channels do not need to be traversed.

If the signal strength corresponding to the channel of which the target first type does not exist is equal to the preset threshold value after the target device finishes traversing each channel of the first type, that is, if no idle channel exists in the channels of the first type, the channel quality of each channel of the first type is compared, and the channel of the first type, the channel quality of which meets the first preset condition, is determined to be a working channel.

Specifically, the channel quality may be determined by parameters such as RSSI, packet loss rate, interference level, congestion level, and adjacent channel interference. It is known that the smaller the RSSI, the lower the occupancy of the channel, i.e. the better the channel quality. The smaller the packet loss rate, the better the channel quality. The lower the interference level, the better the channel quality. The lower the congestion level, the better the channel quality. The weaker the adjacent channel interference, the better the channel quality. In the embodiment of the application, the channel quality can be determined by part or all of the parameters. When the channel quality is determined by using multiple parameters together, the multiple parameters may be weighted and summed to obtain a final result. The weights of the parameters can be default weights which are set uniformly, and can also be set by a user according to the self requirements, and the embodiment of the application is not limited to the default weights.

Alternatively, the first type of channel that satisfies the first preset condition may be a first type of channel with the best channel quality. That is, the first type of channel having the best channel quality is determined as the operation channel, so that the best transmission effect of the selected operation channel can be ensured.

Alternatively, the first type of channel that satisfies the first preset condition may be any one of a plurality of first type channels with better channel quality. For example, the quality of each channel may be sorted from large to small, and one channel may be selected as the working channel from among channels of the channel quality rank 3.

In a specific implementation, after the target device scans all the channels of the first type, there may be all channels of the first type that have poor quality (serious channel congestion), and then a second type of channel may be scanned at this time, and an operating channel may be selected from the second type of channels.

Specifically, if the channel quality of each first type of channel does not meet the second preset condition, sequentially traversing each second type of channel, and determining a working channel according to the traversing result of each second type of channel.

Wherein the second type is different from the first type. The second preset condition is different from the first preset condition.

Specifically, the second preset condition may be that the channel idle time idle_time of the first type of channel is smaller than a time threshold and/or that the noise_floor of the first type of channel exceeds a noise threshold. Where idle_time is used to describe the time when the device is in an inactive state. The larger the parameter, the longer the channel idle time, the better the channel quality. noise floor is the ambient noise of the channel. The smaller the parameter, the less noise that indicates the channel and the lower the channel quality.

When the idle time of each first type of channel is smaller than the time threshold and/or the noise of each first type of channel is larger than the noise threshold, the congestion of each first type of channel is indicated, that is, each first type of channel cannot be used as a working channel. Then at this point the second type of channel may be scanned and an operating channel selected from the second type of channel.

The process of selecting an operating channel from the second type of channel and the process of selecting an operating channel from the first type of channel and the basis are similar, and the idle channel is preferentially selected as the operating channel. And if no idle channel exists, selecting a channel with channel quality meeting a first preset condition as a working channel. Specific choices are made according to the description of the previous embodiments, and are not repeated here.

After the working channel is determined, the target device can perform data transmission on the working channel to realize wireless communication. Then data transmission may be performed on the working channel after the first random delay less target device completes the selection of that channel. And then, when the target equipment with larger first random delay starts to select the channel, the quality of the channel which is selected before can be used as the basis of the current selection, so that the situation that the same channel is selected at the same time is avoided reasonably.

That is, since each target device generates the first random delay when being powered on, the first random delays of the target devices may be different, and the time when each target device starts to select the working channel after the first random delay is finished is different, so that the finally selected working channel may be randomly scattered.

Referring to fig. 3, fig. 3 illustrates a schematic diagram of channel concentration and channel random dispersion. For convenience of description, the embodiment of the application uses a 5G channel as an example for schematic illustration. As shown in fig. 3A, when a plurality of devices are turned on at the same time, the same working channel is easily selected, and a channel concentration condition occurs, so that signals interfere with each other, and problems such as degradation of communication quality, data transmission errors, connection interruption and the like can occur. As shown in fig. 3B, each device may have a different delay time by performing a random delay before selecting an operating channel. Therefore, when the channels are selected, a certain time difference exists, the probability of selecting the same channel at the same time is reduced, so that channel conflict is avoided, the occurrence of channel concentration is effectively prevented, and each channel is reasonably selected.

Further, after determining the working channel, the transmitting device performs data transmission on the working channel and detects channel quality of adjacent channels of the working channel. In particular, channel quality may be commonly determined based on a number of parameters including, but not limited to, channel bit error rate, RSSI, and channel signal to noise ratio. Taking RSSI as an example, when the RSSI of the adjacent channel is greater than-40 dBm, it indicates that the adjacent channel is performing high-power data transmission, and when the signal on the adjacent channel and the signal on the working channel of the transmitting device are simultaneously transmitted, the receiving end may not correctly decode the signal, resulting in communication failure or data error, so that larger interference is generated, and it is determined that the channel quality of the adjacent channel is lower.

Further, after the target device selects the working channel and starts data transmission, the channel quality of the adjacent channel of the working channel can be detected, and when the channel quality of the adjacent channel meets the third preset condition, the working channel is switched to realize the frequency band isolation from surrounding devices. Wherein the third preset condition may be that the RSSI of the channel is greater than a certain value, such as, but not limited to, greater than-40 dBm. That is, if the signal strength of the adjacent channel is strong, it means that the device selecting the adjacent channel may be located near the current target device, so that a certain interference may be generated on the signal transmission of the target device, and then the dynamic switching of the working channel may be performed at this time, and the device switches to the channel with weak channel strength of the adjacent channel, so as to realize the frequency band isolation from the surrounding devices.

Referring to fig. 4, fig. 4 is a schematic diagram of channel switching according to an embodiment of the application. As shown in fig. 4, after the device in classroom 1 selects channel 153 as the working channel, if the signal strength of its adjacent channel 149 is detected to exceed-40 dBm, it means that the device selecting channel 149 may be a device located near classroom 1 (e.g., a device in the left classroom of classroom 1), and in order to avoid signal interference between channels, the device in classroom 1 may switch its working channel from channel 153 to channel 157, thereby implementing band isolation with the device selecting channel 149, reducing signal interference between each other, and improving communication quality.

In a specific implementation, there may be a first random time generated by a plurality of devices that is the same, then the same operating channel is selected, and then the channel quality of the adjacent channels is detected simultaneously. To avoid switching devices to the same operating channel after band isolation in this case, embodiments of the present application may implement further discretization by a second random delay.

Specifically, after the first random delay finishes selecting the working channel, the target device may generate a second random delay time, detect the channel quality of the adjacent channel of the working channel after the second random delay time arrives, and switch the working channel when the channel quality of the adjacent channel meets a third preset condition. The second random delay time generation process is similar to the first random delay time generation process, and will not be described herein.

In addition, in the process of data transmission, the target equipment can also continuously monitor the data transmission quality, identify interference according to the monitoring result and the current wireless network load condition, and dynamically adjust the wireless channel, thereby realizing channel self-adaptive adjustment. For example, when the packet loss rate of the data transmission is monitored to be serious, or the data transmission delay is monitored to be serious, it can be determined that the current data transmission quality is poor, and the working channel needs to be switched. And then selecting a proper channel as a new working channel by combining the scanning results of all channels of the current wireless network, so as to ensure the stability of data transmission.

Further, when the target device detects that the adjacent channel occupancy of the working channel is low, the target device can also perform spread spectrum processing on the current working channel. That is, if the adjacent channel of the working channel is an idle channel, the bandwidth of the working channel can be expanded, so as to further improve the effect of data transmission. Referring to fig. 5, fig. 5 is a schematic diagram of an extended bandwidth provided in an embodiment of the present application. As shown in fig. 5, the working channel of the target device is channel 153, and the bandwidth of the channel is 20M. But both the adjacent channel 149 and channel 157 are idle channels, the bandwidth of the channels can be spread from 20M to 40M. The magnitude of the spreading is not limited in a particular implementation and the embodiments are not claimed to be so limited.

The embodiment of the application can start wireless channel configuration processing based on the channel quality of each channel in the wireless network after the delay is finished if a plurality of receiving devices are started at the same time in the wireless transmission system comprising a plurality of receiving devices, and the opportunity of selecting the working channels among the devices is staggered by carrying out the random delay, then carrying out the configuration processing of the wireless channels, selecting the corresponding working channels, improving the efficiency of selecting the channels by the devices and ensuring the stability of the wireless network. Further, after the working channel is selected and data transmission is performed, further dispersion of the channel can be realized through the second random delay time when the working channel is dynamically switched, so that the transmission quality of wireless data is further ensured. In addition, the embodiment of the application can realize the self-adaptive adjustment of the channel and the channel spread spectrum by monitoring the quality of each channel in the process of data transmission, thereby improving the effect of data transmission.

In some possible embodiments, when each device is powered on simultaneously, each device performs a first random delay according to a random number generated by its own timer. After the delay is finished, the first for loop is entered for traversing, and whether a 5G idle channel exists or not is searched. The criterion for the 5G idle channel may be the signal strength in the channel mentioned in the previous embodiment. For example, if the signal strength is-128 dBm, then the channel may be determined to be a 5G idle channel. That is, when the signal strength of a channel traversed to the channel is-128 dBm, the channel can be determined to be a 5G idle channel, so that the traversing is finished, the channel number of the channel is returned, and the channel is taken as a working channel.

If the signal strength of the channel which does not exist after the traversing is-128 dBm, the 5G idle channel is not present. And then the second for cycle is entered for traversing, and the channel quality of each channel is obtained. After obtaining the channel quality of each channel, determining the channel with the best channel quality, if the channel quality of the channel meets the second preset condition, returning the channel number of the channel, and taking the channel as a working channel.

If the channel quality of the channel does not meet the second preset condition, it indicates that all the 5G channels are poor in quality, that is, there is no available 5G channel, so that the third for loop is entered for traversing to find out whether there is a 2.4G idle channel. The criterion for the 2.4G idle channel may be the signal strength in the channel mentioned in the previous embodiment. For example, if the signal strength is-128 dBm, then the channel may be determined to be a 2.4G idle channel. That is, when the signal strength of a channel traversed to the channel is-128 dBm, the channel can be determined to be a 2.4G idle channel, so that the traversing is finished, the channel number of the channel is returned, and the channel is taken as a working channel.

If the signal strength of the channel which does not exist after the traversing is-128 dBm, the 2.4G idle channel is not existed currently. And then a fourth for cycle is entered for traversing, and the channel quality of each channel is obtained. After obtaining the channel quality of each channel, determining the channel with the best channel quality, returning the channel number of the channel, and taking the channel as a working channel.
