[0029] The data transmission method provided by the embodiments of the present disclosure may be executed by a computer device, which may be understood as any device with processing and computing capabilities, and may include but is not limited to mobile terminals such as smart phones, laptops, personal digital assistants (PDAs), tablet computers (PADs), portable multimedia players (PMPs), vehicle-mounted terminals, wearable devices, etc., as well as fixed electronic devices such as digital TVs, desktop computers, smart home devices, etc.

[0030] In order to better understand the inventive concept of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure are described below in conjunction with exemplary embodiments.

[0031] Figure 1 is a flow chart of a data transmission method provided by an embodiment of the present disclosure, and the method can be executed by a computer device, such as Figure 1 As shown, the data transmission method provided in this embodiment includes the following steps:

[0032] Step 110: monitor the signal quality of each of the high-frequency channels and low-frequency channels accessed during the current period.

[0033] In the disclosed embodiment, the computer device has a dual-channel communication function, and can access the high-frequency channel and the low-frequency channel at the same time, and transmit data based on the high-frequency channel and the low-frequency channel at the same time. The high-frequency channel is used to transmit high-frequency signals, and the low-frequency channel is used to transmit low-frequency signals. The high-frequency channel has a high bandwidth; the low-frequency channel has a strong signal attenuation resistance and high penetration.

[0034] The frequency of high-frequency signals is usually between several hundred kilohertz (kHz) and several hundred megahertz (MHz). They have high frequencies, short wavelengths, and fast propagation speeds. They are easily affected by atmospheric disturbances and obstacles such as buildings, resulting in signal attenuation.

[0035] The frequency of low-frequency signals is generally between a few hertz (Hz) and several thousand hertz (kHz). It has a lower frequency, longer wavelength, and slower propagation speed, but it has a strong diffraction ability and can better penetrate buildings or the ground. It has a long propagation distance and can expand the coverage of wireless communication networks. In addition, low-frequency signals consume less energy during transmission, which helps to extend the battery life of the device.

[0036] The computer device can monitor the signal quality of each of the high-frequency channels and low-frequency channels accessed during the current period.

[0037] Step 120: Based on the signal quality of each of the high-frequency channel and the low-frequency channel, the target data to be transmitted is divided into first data to be transmitted in the high-frequency channel and second data to be transmitted in the low-frequency channel.

[0038] In the embodiment of the present disclosure, after obtaining the signal quality of each channel in the high-frequency channel and the low-frequency channel, the computer device can divide the target data to be transmitted into first data to be transmitted in the high-frequency channel and second data to be transmitted in the low-frequency channel based on the signal quality of each channel in the high-frequency channel and the low-frequency channel.

[0039] Specifically, the target data to be transmitted may be multimedia data, such as audio and video data.

[0040] The first data to be transmitted may include main data in the target data to be transmitted, for example, may be main data in multimedia data.

[0041] The second data to be transmitted includes redundant data in the target data to be transmitted, for example, may be redundant data in multimedia data.

[0042] Redundant data can be understood as redundant or repeated information in the main data. For example, redundant data can include spatial redundant data, temporal redundant data, coding redundant data, visual redundant data, structural redundant data, information entropy redundant data, and knowledge redundant data. Redundant data can help devices achieve data recovery.

[0043] Step 130: Send the first data to be transmitted to the receiving device through the high-frequency channel, and send the second data to be transmitted to the receiving device through the low-frequency channel.

[0044] In the embodiment of the present disclosure, the computer device may send the first data to be transmitted to the receiving device through a high-frequency channel, and send the second data to be transmitted to the receiving device through a low-frequency channel.

[0045] The receiving device can be understood as an electronic device, which can be understood as any device with processing and computing capabilities. The device can include but is not limited to mobile terminals such as smart phones, laptops, personal digital assistants (PDAs), tablet computers (PADs), portable multimedia players (PMPs), vehicle-mounted terminals, wearable devices, etc., as well as fixed devices such as digital TVs, desktop computers, smart home devices, etc.

[0046] For example, when the first data to be transmitted is main data in the target data to be transmitted, and the second data to be transmitted is redundant data in the target data to be transmitted, the receiving device can recover the main data based on the redundant data.

[0047] Therefore, the amount of data that needs to be transmitted in each of the high-frequency channel and the low-frequency channel can be determined based on the signal quality of the high-frequency channel and the signal quality of the low-frequency channel, and then the target data to be transmitted can be sent to the receiving device through the high-frequency channel and the low-frequency channel. The advantages of the high bandwidth of the high-frequency channel and the advantages of the high signal attenuation resistance and high penetration of the low-frequency channel can be combined for data transmission, which can reduce the interference of complex environments on signal transmission, improve the signal's anti-attenuation ability in complex environments, and improve the reliability and stability of data transmission.

[0048] Figure 2 is a flow chart of a data transmission method provided by an embodiment of the present disclosure, and the method can be executed by a computer device, such as Figure 2 As shown, the data transmission method provided in this embodiment includes the following steps:

[0049] Step 210: Obtain channel parameters of each of the high-frequency channels and low-frequency channels accessed during the current period.

[0050] In the embodiments of the present disclosure, the channel parameters of a channel may be understood as data reflecting the signal quality of the channel.

[0051] The channel parameters of the channel may include at least one parameter of the signal strength, signal-to-noise ratio, environmental data, user behavior data, and channel state information of the computer device.

[0052] Among them, the signal strength (Received Signal Strength Indication, RSSI) can be understood as the signal strength indication received by the computer device. It is used to measure the strength of the wireless signal received by the computer device. It is usually expressed in decibel milliwatts (dBm), which reflects the clarity and reliability of the signal.

[0053] The signal-to-interference plus noise ratio (SNR) can be understood as the ratio of the strength of the useful signal received by the computer device to the strength of the received interference signal (noise and interference).

[0054] Environmental data may be understood as environmental data around a computer device collected by sensors installed on the computer device, and may include, for example, temperature, humidity, air pressure, and the like.

[0055] The user behavior data type can be understood as the type of data generated by the user operating the computer device, for example, it may include media data, instruction data and other types.

[0056] Channel State Information (CSI) can be understood as the channel property of the communication link, which describes the attenuation factor of the signal transmitted on the channel, that is, the value of each element in the channel gain matrix H, such as signal scattering, environmental attenuation, distance attenuation and other information.

[0057] Step 220: For each channel, evaluate the signal quality of the channel based on the channel parameters of the channel.

[0058] In the embodiment of the present disclosure, for each channel, the computer device may evaluate the signal quality of the channel based on the channel parameters of the channel.

[0059] In some embodiments, the computer device may evaluate the signal quality of the channel through an adaptive multi-parameter fusion detection mechanism, which may evaluate the channel quality in real time and predict the future channel state by fusing multiple parameters and adaptive algorithms. Compared with traditional methods, the adaptive multi-parameter fusion detection mechanism not only considers the signal strength and noise level, but also integrates the time-varying characteristics, spectrum characteristics and environmental factors of the signal. Specifically, for each channel, based on the channel parameters of the channel, evaluating the signal quality of the channel may include S11-S14:

[0060] S11. For each channel, obtain the weight corresponding to each parameter in the channel parameters of the channel, where the weight is positively correlated with the influence of the parameter on data transmission.

[0061] The greater the influence of a parameter on data transmission, the greater the corresponding weight of the parameter; the smaller the influence of a parameter on data transmission, the smaller the corresponding weight of the parameter.

[0062] The computer device may determine the weight corresponding to each parameter in advance according to the degree of influence of each parameter on data transmission.

[0063] S12: Perform weighted summation on each parameter in the channel parameters of the channel and the weight corresponding to each parameter to obtain a fusion parameter of the channel.

[0064] For example, when the parameters in the channel parameters include the signal strength, signal-to-noise ratio, environmental data and user behavior data type, and channel state information of a computer device, the product of the signal strength and the weight corresponding to the signal strength, the product of the signal-to-noise ratio and the weight corresponding to the signal-to-noise ratio, the product of the environmental data and the weight corresponding to the environmental data, the product of the user behavior data type and the weight corresponding to the user behavior data type, and the channel state information and the product of the weight corresponding to the channel state information can be summed to obtain the fusion parameters of the channel.

[0065] S13. Sum each parameter in the channel parameters of the channel to obtain a parameter sum value.

[0066] S14. Calculate the ratio between the fusion parameter and the parameter sum value to obtain the signal quality of the channel.

[0067] Step 230: When the signal quality of the high frequency channel is greater than or equal to a preset threshold, the target data to be transmitted is determined as the first data to be transmitted of the high frequency channel.

[0068] In the embodiment of the present disclosure, when the signal quality of the high-frequency channel is greater than or equal to a preset threshold, it means that the signal quality of the high-frequency channel is good. At this time, the computer device can determine the target data to be transmitted as the first data to be transmitted of the high-frequency channel, that is, the high-frequency channel sends the target data to be transmitted to the receiving device.

[0069] The preset threshold can be set as needed and is not limited here.

[0070] Step 240: When the signal quality of the high-frequency channel is less than a preset threshold and the signal quality of the low-frequency channel is greater than or equal to the preset threshold, based on the signal quality of each channel in the high-frequency channel and the low-frequency channel, the target data to be transmitted is divided into first data to be transmitted in the high-frequency channel and second data to be transmitted in the low-frequency channel.

[0071] In the embodiment of the present disclosure, when the signal quality of the high-frequency channel is less than a preset threshold and the signal quality of the low-frequency channel is greater than or equal to the preset threshold, it means that the signal quality of the high-frequency channel is poor and the signal quality of the low-frequency channel is good. At this time, the computer device can divide the target data to be transmitted into first data to be transmitted in the high-frequency channel and second data to be transmitted in the low-frequency channel based on the signal quality of each channel in the high-frequency channel and the low-frequency channel.

[0072] Step 250: Send the first data to be transmitted to the receiving device through the high-frequency channel, and send the second data to be transmitted to the receiving device through the low-frequency channel.

[0073] Therefore, the signal quality of the channel can be comprehensively evaluated through multiple channel parameters of the channel, and the amount of data that needs to be transmitted in each channel of the high-frequency channel and the low-frequency channel can be determined according to the signal quality of the high-frequency channel and the signal quality of the low-frequency channel. Then, the target data to be transmitted is sent to the receiving device through the high-frequency channel and the low-frequency channel. The advantages of the high bandwidth of the high-frequency channel and the advantages of the high signal attenuation resistance and high penetration of the low-frequency channel can be combined for data transmission, which can reduce the interference of complex environments on signal transmission, improve the anti-attenuation ability of signals in complex environments, and improve the reliability and stability of data transmission.

[0074] Figure 3 is a flow chart of a data transmission method provided by an embodiment of the present disclosure, and the method can be executed by a computer device, such as Figure 3As shown, the data transmission method provided in this embodiment includes the following steps:

[0075] Step 310: Monitor the signal quality of each of the high-frequency channels and low-frequency channels accessed during the current period.

[0076] Step 320: Sum the signal quality of the high frequency channel and the signal quality of the low frequency channel to obtain a quality sum value.

[0077] Step 330: Calculate a first ratio between the signal quality and the quality sum value of the high frequency channel, and determine the percentage of the first ratio as a first data transmission ratio of the high frequency channel.

[0078] Step 340: Calculate a second ratio between the signal quality of the low-frequency channel and the quality sum value, and determine the percentage of the second ratio as a second data transmission ratio of the low-frequency channel.

[0079] Step 350: extract data of the first data transmission ratio from the target data to be transmitted to obtain first data to be transmitted.

[0080] Step 360: extract data of the second data transmission ratio from the target data to be transmitted to obtain second data to be transmitted.

[0081] Step 370: Send the first data to be transmitted to the receiving device through the high-frequency channel, and send the second data to be transmitted to the receiving device through the low-frequency channel.

[0082] Therefore, the amount of data that needs to be transmitted in each of the high-frequency channel and the low-frequency channel can be determined based on the signal quality of the high-frequency channel and the signal quality of the low-frequency channel, and then the target data to be transmitted can be sent to the receiving device through the high-frequency channel and the low-frequency channel. The advantages of the high bandwidth of the high-frequency channel and the advantages of the high signal attenuation resistance and high penetration of the low-frequency channel can be combined for data transmission, which can reduce the interference of complex environments on signal transmission, improve the signal's anti-attenuation ability in complex environments, and improve the reliability and stability of data transmission.

[0083] In some embodiments of the present disclosure, before sending the first data to be transmitted to the receiving device via the high-frequency channel and sending the second data to be transmitted to the receiving device via the low-frequency channel, the computer device may execute Figure 4 A flowchart of a data transmission method is provided, such as Figure 4 As shown, the data transmission method provided in this embodiment includes the following steps:

[0084] Step 410: Obtain the signal quality of each of the high-frequency channels and low-frequency channels accessed in a preset historical period before the current period.

[0085] The preset historical period can be understood as a period before the current period. The preset historical period can be set as needed, such as the past week, and there is no limitation here.

[0086] Step 420: Perform time series analysis on the signal quality of each channel in the preset historical period to obtain the signal quality trend of each channel in the preset historical period.

[0087] In an embodiment of the present disclosure, after obtaining the signal quality of each of the high-frequency channels and low-frequency channels accessed within a preset historical period, the computer device can perform a time series analysis on the signal quality of each channel within the preset historical period, that is, analyzing the changes in the signal quality of the high-frequency channels within the preset historical period in chronological order to obtain the signal quality trend of the high-frequency channels within the preset historical period, and analyzing the changes in the signal quality of the low-frequency channels within the preset historical period in chronological order to obtain the signal quality trend of the low-frequency channels within the preset historical period.

[0088] Step 430: predict the signal quality of each channel in the current time period based on the signal quality trend of each channel.

[0089] In an embodiment of the present disclosure, a computer device can predict the signal quality of a high-frequency channel in a current period based on the signal quality trend of the high-frequency channel in a preset historical period; and can predict the signal quality of a low-frequency channel in the current period based on the signal quality trend of the low-frequency channel in a preset historical period.

[0090] Step 440: When the signal quality of the high frequency channel in the current time period is less than the preset threshold and the signal quality of the low frequency channel is greater than or equal to the preset threshold, the key data in the target data to be transmitted is sent to the receiving device through the high frequency channel before the current time period arrives.

[0091] In an embodiment of the present disclosure, when the signal quality of the high-frequency channel in the current time period is less than a preset threshold and the signal quality of the low-frequency channel is greater than or equal to the preset threshold, it means that the signal quality of the high-frequency channel in the current time period is poor and the signal quality of the low-frequency channel is good. At this time, the computer device can send the key data in the target data to be transmitted to the receiving device through the high-frequency channel before the current time period arrives.

[0092] For example, the key data may be key frame data in multimedia data.

[0093] In this way, key data in the target data to be transmitted can be sent to the receiving device in advance before the network quality of the high-frequency channel deteriorates, which can further reduce the interference of complex environments on signal transmission, improve the signal's anti-attenuation ability in complex environments, and improve the reliability and stability of data transmission.
