It should be noted that, in the present disclosure, the embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, a flow chart of an embodiment of a data transmission method according to the disclosure is shown, as shown in fig. 1, the data transmission method includes the following steps:
step S101, obtaining the network state parameter of the current moment, wherein the network state parameter comprises the network transmission rate.
The network status parameters of the used network can be obtained in real time. The network used herein may be a wired network and a wireless network. The wireless network may include, but is not limited to, a 2G network, a 3G network, a 4G network, and a 5G network.
The network state parameters are used for characterizing the network state of the used network. Here, the network status parameters may include, for example: network transmission rate, data transmission delay, etc.
The network transmission rate may be obtained based on the flow shown in step S1011 to step S1012 in fig. 2.
In step S1011, the transmission data amount in the preset time period before the current time and adjacent to the current time is obtained.
The preset time period may include, but is not limited to, 30 seconds, 1 minute, 2 minutes, 5 minutes.
Here, when the transmission data amount in the preset time period is acquired, timing may be started from the time when the transmission data amount starts to be acquired according to the duration of the preset time period, and the acquisition operation may be ended at the corresponding termination time after the duration, that is, the transmission data amount in the preset time period may be counted.
Step S1012, obtaining the network transmission rate of the preset time period based on the transmission data amount and the duration of the preset time period, and taking the network transmission rate of the preset time period as the current network transmission rate.
Specifically, the network transmission rate may be obtained by taking the quotient of the transmission data amount and the duration of the preset time period. The duration of the preset time period may be set to be relatively short, for example, 30 seconds or 20 seconds, so that the network transmission rate obtained according to the data amount transmitted in the previous preset time period may be regarded as the real-time network transmission rate at the current time.
And step S102, determining a compression ratio corresponding to the current moment according to the network state parameters and a pre-established network state-compression ratio mapping relation, wherein the network state-compression ratio mapping relation is used for determining the data compression ratio according to the network state parameters.
In some application scenarios, different network state parameters may be mapped to several preset compression rates through a network state-compression rate mapping relationship. Specifically, the network state-compression ratio mapping relationship includes a plurality of network transmission rate intervals and preset compression ratios corresponding to the plurality of network transmission intervals, and the preset compression ratios corresponding to different network transmission intervals are different.
Referring to fig. 3, which shows a schematic flowchart of determining a compression rate corresponding to a current time according to the present disclosure, as shown in fig. 3, the above step S102 includes the following steps S1021 to S1022.
Step S1021, determining a network transmission rate interval corresponding to the network transmission rate at the current time.
Step S1022, a preset compression ratio corresponding to the network transmission rate interval is searched from the network state-compression ratio mapping relationship, and the preset compression ratio is determined as the compression ratio corresponding to the current time.
It should be appreciated that the plurality of network transmission rate intervals included in the network state-compression ratio mapping relationship may be preset. In the network state-compression ratio mapping relationship, the preset compression ratios corresponding to different network transmission intervals are different. Taking the example that the network utterance intervals include a first network transmission rate interval and a second network transmission rate interval, a first preset compression rate corresponding to the first network transmission rate interval is greater than a second preset compression rate corresponding to the second network transmission rate interval. Wherein any network transmission rate in the first network transmission rate interval is greater than any network transmission rate in the second network transmission rate interval.
For example, when the network state corresponding to the first network transmission rate interval is the 2G network state, in the network state-compression ratio mapping relationship, the preset compression ratio in the 2G network state is 40%; when the network state corresponding to the second network transmission rate interval is the 3G network state, in the network state-compression ratio mapping relationship, the preset compression ratio in the 3G network state is 60%. That is, in the 2G network state, a plurality of different first network transmission rates are included, and each of the plurality of first network transmission rates corresponds to a compression rate (i.e. 40%); in the 3G network state, a plurality of different second network transmission rates are included, and the plurality of second network transmission rates all correspond to a compression rate (i.e. 60%), so that the network transmission rates in the same network state all correspond to a compression rate, the fluctuation range of the compression rate is small in the object transmission process, and the distortion degree difference of each part of the transmission object is small. For example, when the first network transmission rate interval is 10-15 Kbit/s, in the network state-compression ratio mapping relationship, the preset compression ratio corresponding to the first network transmission rate interval is 35%; when the second network transmission rate interval is 15-20 Kbit/s, in the network state-compression ratio mapping relationship, the preset compression ratio corresponding to the second network transmission rate interval is 45%, each network transmission rate in the first network transmission rate interval corresponds to a compression ratio (i.e. 35%), each network transmission rate in the second network transmission rate interval corresponds to a compression ratio (i.e. 45%), and the purpose of small distortion difference of each part of transmission data can be achieved.
Furthermore, the preset compression ratios corresponding to different intervals are different, and the value range of the compression ratio corresponding to each interval is 25% -1, so that the transmission object can be matched with the corresponding compression ratio in different network states, and the problem of excessive distortion of the transmission object can be avoided.
When the network transmission rate at the current moment is obtained, the network transmission rate interval corresponding to the network transmission rate at the current moment can be determined according to the network state-compression ratio mapping relation.
It should be noted that, when setting the preset compression rate corresponding to each network transmission rate interval, the set compression rate is preferably used, and the transmission object can be transmitted to the receiving end through the network. On the premise of ensuring that the transmission object can be transmitted to the receiving end through the network, the fidelity of the data is met as much as possible. For example, when the transmission object is a picture, when a preset compression rate corresponding to a network rate transmission interval is set, and when the network rate transmission in the interval is used, the picture compressed according to the preset compression rate can be transmitted to a receiving end firstly, and then the picture compressed according to the preset compression rate can obtain higher fidelity after being decompressed by the receiving end.
And S103, compressing the data to be transmitted of the transmission object at the current moment according to the compression rate, and transmitting the compressed data to be transmitted.
For the same transmission object, in the transmission process, if the network state parameters at different times are different, the compression rates corresponding to the data to be transmitted at the different times are also different. Accordingly, the fidelity of the transmission object received by the receiving end is also different.
In the prior art, the compression ratio of data to be transmitted is fixed, and the compression ratio cannot be adjusted according to network state parameters. Thus, when the network transmission rate is poor, the data may not be successfully transmitted, and when the network transmission rate is good, the fidelity of the transmission object may be low, both of which may reduce the user experience.
According to the embodiment, the compression ratio corresponding to the current moment is determined according to the network state parameter of the current moment and the pre-established network state-compression ratio mapping relation, so that the data to be transmitted of the transmission object at the current moment is compressed, and the compressed data to be transmitted is transmitted, so that the transmission object has high fidelity on the basis of ensuring the transmission object is successfully transmitted when the network state is good; and when the network state is poor, the transmission object can be ensured to be successfully transmitted at a higher speed, and the user experience is effectively improved.
In some optional implementations of this embodiment, the network state-compression ratio mapping relationship includes a preset function that maps different network state parameters to different compression ratios. In these optional implementation manners, the determining, according to the network state parameter and the pre-established network state-compression ratio mapping relationship in step S102, a compression ratio corresponding to the current time may include: and determining the compression rate corresponding to the current moment according to the preset function and the network state parameter of the current moment.
The network state-compression ratio mapping relationship may be constructed according to historical compression ratios corresponding to a plurality of historical network transmission rates and a plurality of historical network transmission rates, respectively. The historical compression rate can ensure that the transmission object is successfully transmitted, and the transmitted object has higher fidelity.
In these alternative implementations, for each network state parameter, there may be a compression rate corresponding to it, the compression rate being transformed with the real-time transformed network state parameter. At any time, the data to be transmitted can be transmitted by using the network transmission rate at the time. Thus, the data transmission efficiency can be improved.
In some optional implementation manners of this embodiment, the data transmission method further includes step S104, and in step S104, the network state-compression ratio mapping relationship is adjusted according to the transmission delay of the compressed data to be transmitted.
And optimizing the corresponding relation between the network state parameters and the compression ratio by continuously adjusting the network state-compression ratio mapping relation to obtain the compression ratio which is most matched with the current network state.
Specifically, step 104 includes the following steps S1041 to S1042.
Step S1041, if the transmission delay is smaller than the preset delay threshold, adjusting the network state-compression ratio mapping relationship to increase the compression ratio corresponding to the data to be transmitted.
Step S1042, if the transmission delay is greater than the preset delay threshold, adjusting the network state-compression ratio mapping relationship to reduce the compression ratio corresponding to the data to be transmitted.
Further, the transmission delay is the time from the beginning of the transmission of the data to be transmitted to the completion of the data transmission; the preset time delay threshold is a preset time length from the beginning to the end of transmission of the data to be transmitted, and can be 5-30s, 1-3 minutes and the like; the compression ratio is the ratio of the size of the file after compression to the size of the file before compression, for example: the file of 100MB was compressed to 90MB, with a compression ratio of 90/100 × 100% to 90%.
That is, when a certain data is transmitted, when the time length from the start of the transmission of the data to the completion of the transmission of the data is shorter than the time length set in advance, the compression ratio corresponding to the data to be transmitted in the network state-compression ratio mapping relationship needs to be increased.
When a certain data is transmitted, when the time length from the beginning of the transmission of the data to the completion of the data transmission is longer than the time length set in advance, the compression ratio corresponding to the data to be transmitted in the network state-compression ratio mapping relationship needs to be reduced.
In the transmission process, if there is a case that the compression ratio is small but the transmission is still unsuccessful (the transmission delay is greater than the preset delay threshold), in the network state-compression ratio mapping relationship, for the same compression ratio, the compression ratio needs to be corresponding to a larger network transmission rate; there are also situations where the compression rate is large but the transmission is successful within a short time period (the transmission delay is smaller than the preset delay threshold), and for the same compression rate, the compression rate needs to be corresponding to a smaller network transmission rate.
Referring to fig. 4, a schematic structural diagram of an embodiment of a data transmission device according to the present disclosure is shown. As shown in fig. 4, the data transmission apparatus includes: an acquisition module 401, a determination module 402 and a compression module 403. The acquiring module 401 is configured to acquire a network state parameter at a current time, where the network state parameter includes a network transmission rate;
a determining module 402, configured to determine a compression ratio corresponding to a current time according to the network state parameter and a pre-established network state-compression ratio mapping relationship, where the network state-compression ratio mapping relationship is used to determine a data compression ratio according to the network state parameter;
the compression module 403 is configured to compress the data to be transmitted of the transmission object at the current time according to the compression rate, and transmit the compressed data to be transmitted.
It should be noted that, for specific processing of the obtaining module 401, the determining module 402, and the compressing module 403 of the data transmission apparatus and the technical effects thereof, reference may be made to the related descriptions of step 101, step 102, and step 103 in the corresponding embodiment of fig. 1, which is not described herein again.
In some optional implementation manners of this embodiment, the network state-compression ratio mapping relationship includes a plurality of network transmission rate intervals and preset compression ratios respectively corresponding to the plurality of network transmission rate intervals, and different network transmission rate intervals correspond to different preset compression ratios; and the determining module 402 is further configured to: determining a network transmission rate interval corresponding to the network transmission rate at the current moment; searching a preset compression ratio corresponding to the network transmission rate interval from the network state-compression ratio mapping relation, and determining the preset compression ratio as a compression ratio corresponding to the current moment; the network transmission method comprises the steps that a first preset compression rate corresponding to a first network transmission rate interval is larger than a second preset compression rate corresponding to a second network transmission rate interval, any network transmission rate in the first network transmission rate interval is larger than any network transmission rate in the second network transmission rate interval, and the first network transmission rate and the second network transmission rate belong to a plurality of network transmission rate intervals.
In some optional implementations of this embodiment, the obtaining module 401 is further configured to: acquiring the transmission data volume before the current time and in a preset time period adjacent to the current time; and obtaining the network transmission rate of the last preset time period based on the transmission data volume and the duration of the preset time period, and taking the network transmission rate of the last preset time period as the current network transmission rate.
In some optional implementations of this embodiment, the apparatus further includes an adjusting module 404, where the adjusting module 404 is configured to: and adjusting the network state-compression ratio mapping relation according to the transmission delay of the compressed data to be transmitted.
In some optional implementations of this embodiment, the adjusting module 404 is further configured to: if the transmission delay is smaller than a preset delay threshold, adjusting the network state-compression ratio mapping relation to increase the compression ratio corresponding to the data to be transmitted;
and if the transmission delay is larger than a preset delay threshold, adjusting the network state-compression ratio mapping relation to reduce the compression ratio corresponding to the data to be transmitted.
The operation of the data transmission device is described below by way of a specific example.
In a pre-established network state-compression ratio mapping relationship, a preset compression ratio corresponding to a 5G network state is 100%, a preset compression ratio corresponding to a 4G network state is 80%, a preset compression ratio corresponding to a 3G network state is 60%, a preset compression ratio corresponding to a 2G network state is 40%, in a state lower than a network transmission rate in the 2G network state, the preset compression ratio corresponding to the state is 25%, the minimum value in preset time delay threshold values is 5s, and the maximum value is 30 s.
When a user wants to send a picture, first, the obtaining module 401 of the device obtains the transmission data volume in the preset time period before and adjacent to the current time, and obtains the current network transmission rate based on the transmission data volume and the duration of the preset time period.
Next, the determining module 402 determines a network transmission rate interval corresponding to the current network transmission rate, if the network state corresponding to the determined network transmission rate interval is a 5G network state, the current compression rate is 100% (that is, compression is not needed), after the picture is compressed by the 100% compression rate and transmits a certain amount of data, the compressing module 403 obtains a change in the current network transmission rate currently obtained by the module 401, if the determining module 402 determines again that the network state corresponding to the network transmission rate interval corresponding to the current network transmission rate is a 4G network state, the current compression rate is 80%, and the compressing module 103 compresses the data to be transmitted at the current time at the 80% compression rate.
When the device compresses the picture at a compression rate of 40% in a 2G network state, the obtained current network transmission rate changes, and if the network state corresponding to the network transmission rate interval corresponding to the current network transmission rate is determined to be a 3G network state again, the current compression rate is changed to 60%.
And by analogy, if the current network transmission rate is changed and the network state needs to be changed, obtaining a preset compression rate corresponding to the current network state based on the changed network state and the network state-compression rate mapping relation, and compressing the data to be transmitted of the picture at the current moment according to the preset compression rate.
Then, if the current network transmission rate is in the 4G network state, but the picture is found to have been successfully sent after a duration of less than 5s, the adjusting module 404 adjusts the current network state-compression ratio mapping relationship, and increases the preset compression ratio in the network state-compression ratio mapping relationship, so that the picture has a greater fidelity; if the current network transmission rate is in the 3G network state, and the picture is still not successfully sent after 30s, the preset compression rate in the network state-compression rate mapping relation is reduced, so that the picture can be successfully sent as soon as possible, and the user experience is improved.
Finally, the compression module 403 compresses the data to be transmitted at the current moment of the picture at the current compression rate until the compressed data to be transmitted is completely transmitted.
In some optional implementations of this embodiment, the network state-compression ratio mapping relationship includes a preset function that maps different network state parameters to different compression ratios; and the determining module 402 is further configured to: and determining the compression rate corresponding to the current moment according to the preset function and the network state parameter of the current moment.
Similarly, the operation of the data transmission device will be described below by way of a specific example.
In the pre-established network state-compression ratio mapping relationship, the network state and the compression ratio are in a functional relationship A1, the minimum value in the preset time delay threshold value is 5s, and the maximum value is 30 s.
When a user wants to send a picture, first, the obtaining module 401 of the device obtains the current network status parameter N1.
Next, the determining module 402 obtains a compression ratio M1 corresponding to the current network state parameter N1 based on the current network state parameter N1 and a preset function a1, the compressing module 403 compresses the data to be transmitted at the current time with the compression ratio M1, after certain data is transmitted, the obtaining module 401 obtains the current network state N2 and obtains the compression ratio M2 corresponding to the current network state parameter N2 based on a preset function a1, and the compressing module 403 compresses the data to be transmitted at the current time with the compression ratio M2.
By analogy, if the current network state parameter changes, the preset compression rate corresponding to the current network state parameter is obtained based on the current network state parameter and the preset function a1, and the data to be transmitted of the picture at the current moment is compressed according to the preset compression rate.
Then, if the picture is successfully sent within a time length of less than 5 seconds under the current network state parameter, the adjusting module 404 adjusts the current preset function a1 to be the function a2, and the function a2 increases the preset compression rate in the network state-compression rate mapping relationship, so that the picture has a higher fidelity; if the picture is not successfully sent after 30 seconds under the current network state parameter, the adjusting module 404 adjusts the current preset function a1 to be the function A3, and the preset compression rate in the network state-compression rate mapping relationship is reduced in the function A3, so that the picture can be successfully sent as soon as possible, and the user experience is improved.
Finally, the compression module 403 compresses the data to be transmitted at the current moment of the picture at the current compression rate until the compressed data to be transmitted is completely transmitted.
