Based on the above mobile terminal hardware structure and communication network system, various embodiments of the present application are provided.

In order to improve the efficiency of the mobile terminal in transmitting data, the inventor thinks that when the mobile terminal is located in both the WIFI network and the cellular network, the data is transmitted through the WIFI network and the cellular network, thereby improving the efficiency of the mobile terminal in transmitting data.

The following describes a data transmission method provided by the present application with reference to specific embodiments.

Fig. 3 is a first flowchart of a data transmission method according to an embodiment of the present application. As shown in fig. 3, the method includes:

s301, when it is detected that the mobile terminal is connected to a WIFI network and a cellular network, judging whether a first Quality of Service (QoS) parameter of an application program currently running on the mobile terminal in the WIFI network meets a preset condition.

The execution main body of the embodiment of the application may be a mobile terminal, or may also be a data transmission device provided in the mobile terminal, and the data transmission device may be implemented by a combination of software and/or hardware.

Alternatively, the cellular network may be 2G, 3G, 4G, 5G, etc.

The mobile terminal can communicate with the public equipment through the WIFI network, so that a first QoS parameter of an application program, which is sent by the public server and currently operated by the mobile terminal under the WIFI network, is obtained.

Alternatively, the public device may be a communication base station, or may be a server corresponding to an application program.

The first QoS parameter includes at least one of a network transmission rate, a transmission delay, a first packet loss rate, and the like of the mobile terminal in the WIFI network.

The number of parameters included in the first QoS parameter is greater than or equal to the number of parameters included in the preset condition.

Optionally, when the first QoS parameter includes a network transmission rate and a transmission delay, the preset condition may include the network transmission rate and/or the transmission delay.

The preset condition is the minimum requirement that the network adopted when the mobile terminal sends data must meet.

Optionally, when the packet loss rate in the preset condition is 0.001, if the first packet loss rate is greater than 0.001, the first QoS parameter does not satisfy the preset condition.

Optionally, when the network transmission rate in the preset condition is 2 kbit/s and the packet loss rate is 0.001, if the network transmission rate in the first QoS parameter is less than 2 kbit/s and the first packet loss rate is greater than 0.001, the first QoS parameter does not satisfy the preset condition.

Optionally, when the network transmission rate in the preset condition is 2 kbit/s, the packet loss rate is 0.001, and the transmission delay is 1 ms, if the network transmission rate in the first QoS parameter is less than 2 kbit/s, the first packet loss rate is greater than 0.001, and the transmission delay is greater than 1 ms, the first QoS parameter does not satisfy the preset condition.

S302, if the first QoS parameter does not meet the preset condition, whether a second QoS parameter of an application program currently operated by the mobile terminal under the cellular network meets the preset condition is judged.

The second QoS parameter includes at least one of a transmission rate, a transmission delay, a second packet loss rate, and the like of the mobile terminal network in the cellular network.

Optionally, the execution method of S302 is similar to the execution method of S301, and the execution process of S302 is not described herein again.

In practical application, since the priority of the WIFI network is usually higher than that of the cellular network, it is determined whether the first QoS parameter meets the preset condition, and then it is determined whether the second QoS parameter meets the preset condition.

Of course, it is also possible to first determine whether the second QoS parameter satisfies the predetermined condition, and then determine whether the first QoS parameter satisfies the predetermined condition.

And S303, if the second QoS parameter does not meet the preset condition, sending the data of the application program through the WIFI network and the cellular network.

Optionally, the data of the application program is sent to the server corresponding to the application program through the WIFI network and the cellular network, and further, the data fed back to the mobile terminal by the server corresponding to the application program can be received through the WIFI network and the cellular network.

In the data transmission method provided in the embodiment of fig. 3, when neither the first QoS parameter nor the second QoS parameter satisfies the preset condition, that is, when both the network quality of the WIFI network and the cellular network is poor, the data of the application program is transmitted through the WIFI network and the cellular network, so that the efficiency of the mobile terminal for transmitting the data is improved.

On the basis of the above embodiments, the data transmission method provided by the embodiments of the present application is further described in detail below with reference to fig. 4.

Fig. 4 is a flowchart illustrating a second method for sending data according to an embodiment of the present application. As shown in fig. 4, the method includes:

s401, detecting that the mobile terminal is connected to a WIFI network and a cellular network.

S402, judging whether a first QoS parameter of an application program currently running in the mobile terminal under the WIFI network meets a preset condition.

If so, perform S403, otherwise perform S404.

And S403, sending the data of the application program through the WIFI network.

S404, judging whether a second QoS parameter of the application program currently operated by the mobile terminal in the cellular network meets a preset condition.

If so, S405 is executed, otherwise, S406-S408 are executed.

S405, switching the network of the mobile terminal from the WIFI network to a cellular network, and sending data of the application program through the cellular network.

S406, determining a first length of a first sending window corresponding to the WIFI network according to the first packet loss rate; and/or determining a second length of a second sending window corresponding to the cellular network according to the second packet loss rate.

In one possible design, when the first packet loss rate is greater than or equal to a preset threshold value, acquiring a second length of a first sending window when the mobile terminal sends data through the WIFI network last time; and determining the ratio of the second length to the first preset value as the first length of the first sending window of the WIFI network.

Alternatively, the first length may be determined by the following equation 1:

C_r＝C_r-1the/R formula 1;

wherein, C_rDenotes a first length, C_r-1Representing the second length and R representing a preset threshold. Alternatively, R equals 2.

Optionally, for one-time data transmission, if the mobile terminal receives a confirmation character corresponding to one-time transmission, determining a square root of the number of networks used by the mobile terminal to transmit data at the current moment, and determining a first ratio of 1 to the square root; the second length and the sum of the first ratio and the second ratio of the second length are determined as the first length.

Alternatively, the first length may be determined by the following equation 2:

wherein, C_rIs a first length, C_r-1Is the second length, N is the number of networks,

is the square root of the square,

the first ratio is a first ratio of the first ratio,

is the second ratio.

The preset threshold may be 0, and may be a value greater than 0 and smaller than the packet loss rate in the preset condition. The first preset value is 2, and can also be 3, 4, etc.

Optionally, for data sent once, after the mobile terminal sends the data using the WIFI network, the length (i.e., the second length) of the first sending window when the mobile terminal executes the data sending this time through the WIFI network is recorded, so that when the mobile terminal sends the data through the WIFI network next time, the last recorded length (i.e., the second length) of the first sending window can be obtained.

The method for determining the second length of the second transmission window corresponding to the cellular network according to the second packet loss rate is the same as the method for determining the first length of the first transmission window corresponding to the WIFI network according to the first packet loss rate, and details are not repeated here.

And S407, transmitting data according to the first length of the first transmission window and/or the second length of the second transmission window.

Alternatively, the data may be transmitted by the following methods 1, 2, 3.

Method 1, data is transmitted according to a first length of a first transmission window.

And 2, transmitting the data according to the second length of the second transmission window.

And 3, transmitting data according to the first length of the first transmission window and the second length of the second transmission window.

In one possible design, the data is divided into a first data packet sequence and/or a second data packet sequence according to the first length and/or the second length; the first sequence of data packets is transmitted through a first transmission window and/or the second sequence of data packets is transmitted through a second transmission window.

Corresponding to the method 1, optionally, the data is divided into a first data packet sequence according to the first length, and the first data packet sequence is transmitted through the first transmission window.

Corresponding to the method 2, optionally, the data is divided into a second data packet sequence according to the second length, and the second data packet sequence is transmitted through the second transmission window.

Corresponding to the method 3, optionally, dividing the data into a first data packet sequence according to the first length, and transmitting the first data packet sequence through the first transmission window; and dividing the data into a second data packet sequence according to the second length, and transmitting the second data packet sequence through a second transmission window.

The number of data packets included in the first sequence of data packets is equal to the first length. The number of data packets included in the second data packet is equal to the second length.

Optionally, the data includes 10 consecutive data packets, the first length is 3 and the second length is 7, the obtained first data packet sequence includes 3 consecutive data packets, the second data packet sequence includes 7 consecutive data packets, the 3 consecutive data packets are consecutive data packets 1 to 3, respectively, and the 7 consecutive data packets are consecutive data packets 1 to 7, respectively.

The data transmission method in the embodiment of fig. 4 is different from the prior art. In the prior art, when the network quality of the WiFi network is poor and the network quality of the cellular network is good, the mobile terminal cannot automatically switch the WiFi network to the cellular network, so in practical applications, when a user uses the mobile terminal to play game entertainment, if the mobile terminal sends data through the WiFi network with poor network quality, the game may be jammed, and the user experience may be reduced. In the application, when the network quality of the WiFi network is poor (that is, the first QoS parameter does not satisfy the preset condition), and the network quality of the cellular network is good (the second QoS parameter satisfies the preset condition), the mobile terminal may send data through the cellular network, so that the game jam is alleviated, and the user experience is improved.

Optionally, in some implementations, when the mobile terminal is located in both the WiFi network and the cellular network, the mobile terminal defaults to using the WiFi network to transmit data, and does not support transmitting data through both the WiFi network and the cellular network, so that the network quality in the WiFi network is poor, resulting in low efficiency of transmitting data by the mobile terminal. In the application, when the mobile terminal is located in the WiFi network and the cellular network at the same time, the data can be transmitted through the cellular network and the WiFi network at the same time, so that when the network quality of the WiFi network is poor, the efficiency of the mobile terminal for transmitting the data can be improved.

Optionally, in some implementations, when the mobile terminal is located in both the WiFi network and the cellular network, the mobile terminal defaults to using the WiFi network to transmit data, and thus the network quality in the WiFi network is poor, resulting in low efficiency of data transmission by the mobile terminal. In the application, when the first QoS parameter meets the preset condition, the data of the application program is sent through the WIFI network, and therefore the problem that the efficiency of sending the data by the mobile terminal is low when the network quality of the WIFI network is poor can be avoided.

Fig. 5 is a third flowchart of a data transmission method according to an embodiment of the present application. As shown in fig. 5, the method includes:

s501, when the mobile terminal is detected to be connected to a WIFI network and a cellular network, whether a first QoS parameter of an application program currently running on the mobile terminal in the WIFI network meets a preset condition is judged.

S502, if the first QoS parameter does not meet the preset condition, judging whether a second QoS parameter of an application program currently operated by the mobile terminal under the cellular network meets the preset condition.

S503, if the second QoS parameter does not satisfy the preset condition, determining whether the application program supports a Multi Path Transmission Control Protocol (MPTCP).

Optionally, it may be determined whether the application supports MPTCP according to the first identifier.

Alternatively, the first flag may be 0 or 1, 1 indicating that the application supports MPTCP, and 0 indicating that the application does not support MPTCP.

If the first identifier is 1, the application program supports MPTCP; if the first flag is 0, the application program does not support MPTCP.

Alternatively, the first identifier may be acquired by the following two methods.

In the mode 1, a mobile terminal sends a first request to a server, wherein the first request is used for requesting to acquire a first identifier, and the first identifier indicates whether MPTCP is supported or not; the server sends a first identifier to the mobile terminal according to the first request;

in the mode 2, the installation file of the application program comprises the first identifier, and the first identifier is written into the mobile terminal when the mobile terminal installs the application program according to the installation file.

And S504, if the data is supported, sending the data of the application program through the WIFI network and the cellular network.

It should be noted that, in the embodiment of fig. 5, when the application supports MPTCP, the data of the application may be transmitted through the WIFI network and the cellular network only through the above S406 to S408.

In the data transmission method implemented and provided in fig. 5, when neither the first QoS parameter nor the second QoS parameter satisfies the preset condition, that is, when the network quality of both the WIFI network and the cellular network is poor, the data of the application program can be transmitted through the WIFI network and the cellular network, so that the efficiency of the mobile terminal for transmitting the data can be improved. And when the application program supports MPTCP, the data of the application program is sent through the WIFI network and the cellular network, and protocol support is provided for the mobile terminal to send the data through the two networks.

Optionally, in S301 in the embodiment of fig. 3 or S402 in the embodiment of fig. 4, the following may also be performed: judging whether the application program supports MPTCP; and if the application program supports MPTCP, judging whether the first QoS parameter of the application program currently operated by the mobile terminal in the WIFI network meets a preset condition.

Optionally, S406 in the embodiment of fig. 4 may also be: judging whether the application program supports MPTCP; if so, determining a first length of a first sending window corresponding to the WIFI network according to a first packet loss rate included in the first QoS parameter.

On the basis of any of the above method embodiments, after the data of the application program is transmitted through the WIFI network and/or the cellular network, the method may further include:

judging whether a third QoS parameter of an application program currently running by the mobile terminal in the WIFI network meets a preset condition or not; and if the third QoS parameter meets the preset condition, restoring the network of the mobile terminal to be the WIFI network. And when data needing to be sent exist next time, sending the data through the WIFI network.

And the third QoS parameter is the parameter of the application program which is obtained again and currently operated by the mobile terminal under the WIFI network. The third QoS parameter includes at least one of a network transmission rate, a transmission delay, a packet loss rate, and the like of the mobile terminal in the WIFI network.

In the application, after the data of the application program is sent through the WIFI network and the cellular network or the cellular network, the network of the mobile terminal can be restored to the WIFI network, the data is sent through the WIFI network, so that the mobile terminal can flexibly determine that the data is sent through the cellular network and/or the WIFI network, and the flexibility of the mobile terminal in sending the data through different networks is improved under the condition of improving the data sending efficiency of the mobile terminal.
