The following describes embodiments of the present application in detail.

Referring to fig. 2, fig. 2 is a schematic flowchart of a link aggregation data transmission method according to an embodiment of the present application, where the link aggregation data transmission method includes:

step 201: the mobile terminal detects a link quality of the first Wi-Fi data link and detects a link quality of the second Wi-Fi data link.

Among them, Wi-Fi (Wireless-Fidelity, Wi-Fi), which may also be called "WiFi" or "WiFi", is a Wireless connection mode. The mobile terminal includes a Wi-Fi module to enable the mobile terminal to have Wi-Fi functionality. The mobile terminal can comprise a first Wi-Fi module and a second Wi-Fi module and can support simultaneous receiving and transmitting of signals of two Wi-Fi frequency bands. The first Wi-Fi module and the second Wi-Fi module support different frequency bands, for example, the first Wi-Fi module supports a 2.4g (hz) frequency band, and the second Wi-Fi module supports a 5g (hz) frequency band; or the first Wi-Fi module supports a 5G (Hz) frequency band, and the second Wi-Fi module supports a 2.4G (Hz) frequency band.

The first Wi-Fi data link is a data connection path which is established between the mobile terminal and the wireless network and is connected through the first Wi-Fi module interface. The second Wi-Fi data link is a data connection path established between the mobile terminal and the wireless network and connected through the second Wi-Fi module interface. The first Wi-Fi data link supports data receiving and sending of a first Wi-Fi frequency band, and the second Wi-Fi data link supports data receiving and sending of a second Wi-Fi frequency band. The first Wi-Fi band is different from the second Wi-Fi band, for example, the first Wi-Fi band is 2.4g (hz) band, and the second Wi-Fi band is 5g (hz) band.

The link quality of the first Wi-Fi data link can be determined by the uplink and downlink data transmission rate, the round-trip delay, the packet loss rate, the bit error rate and the like of the first Wi-Fi data link. The higher the transmission rate of the uplink and downlink data, the smaller the round-trip delay, the lower the packet loss rate and the bit error rate, and the higher the link quality of the first Wi-Fi data link; the lower the transmission rate of the uplink and downlink data, the larger the round-trip delay, the higher the packet loss rate and the higher the error rate, and the lower the link quality of the first Wi-Fi data link. Similarly, the link quality of the second Wi-Fi data link may be determined by the uplink and downlink data transmission rate, the round trip delay, the packet loss rate, the bit error rate, and the like of the second Wi-Fi data link.

The link quality of the first Wi-Fi data link can be scored based on the uplink and downlink data transmission rate, the round-trip delay, the packet loss rate and the bit error rate of the first Wi-Fi data link, so that the quality score of the first Wi-Fi data link is obtained. Similarly, the link quality of the second Wi-Fi data link may be scored based on the uplink and downlink data transmission rate, the round trip delay, the packet loss rate, and the bit error rate of the second Wi-Fi data link, so as to obtain a quality score of the second Wi-Fi data link.

Wherein the first Wi-Fi data link comprises a first Wi-Fi uplink and a first Wi-Fi downlink. The quality of the first Wi-Fi uplink data link is determined by the uplink data transmission rate, round-trip delay, packet loss rate, bit error rate and the like of the first Wi-Fi uplink data link. The quality of the first Wi-Fi downlink data link is determined by the transmission rate, the round-trip delay, the packet loss rate, the bit error rate and the like of the downlink data of the first Wi-Fi downlink data link. Similarly, the second Wi-Fi data link includes a second Wi-Fi uplink data link and a second Wi-Fi downlink data link.

Before executing step 201, the mobile terminal starts the intelligent link aggregation function and only opens the Wi-Fi connection.

Link aggregation means that a mobile terminal can use two or more network ports to surf the internet at the same time, for example, two Wi-Fi networks can be opened at the same time for network access through link aggregation on a smart phone. The intelligent Link Aggregation (SLA) function refers to intelligently distributing the internet surfing requests of users to different internet surfing interfaces (a first Wi-Fi module interface and a second Wi-Fi module interface).

Specifically, the embodiment of the mobile terminal detecting the link quality of the first Wi-Fi data link may be:

the mobile terminal measures the data transmission rate, the round-trip delay, the packet loss rate and the bit error rate of a first Wi-Fi data link; and determining the link quality of the first Wi-Fi data link based on the data transmission rate, the round trip delay, the packet loss rate and the bit error rate of the first Wi-Fi data link.

Specifically, the embodiment of the mobile terminal detecting the link quality of the second Wi-Fi data link may be as follows:

the mobile terminal measures the data transmission rate, the round-trip delay, the packet loss rate and the bit error rate of the second Wi-Fi data link; determining link quality of the second Wi-Fi data link based on data transmission rate, round-trip delay, packet loss rate and bit error rate of the second Wi-Fi data link;

specifically, the embodiment of the mobile terminal detecting the link quality of the first Wi-Fi data link and detecting the link quality of the second Wi-Fi data link may be as follows:

the mobile terminal measures the maximum data transmission rate of a first Wi-Fi data link and measures the maximum data transmission rate of a second Wi-Fi data link; determining a link quality of the first Wi-Fi data link and a link quality of the second Wi-Fi data link based on the maximum data transmission rate of the first Wi-Fi data link and the maximum data transmission rate of the second Wi-Fi data link.

In the embodiment of the application, the link quality of the first Wi-Fi data link and the link quality of the second Wi-Fi data link are calculated according to the following formulas:

weigh_wi-fi_1＝max_speed_wi-fi_1/(max_speed_wi-fi_1+max_speed_wi-fi_2)；

weigh_wi-fi_2＝max_speed_wi-fi_2/(max_speed_wi-fi_1+max_speed_wi-fi_2)；

wherein, weight _ Wi-Fi _1 represents the link quality of the first Wi-Fi data link, weight _ Wi-Fi _2 represents the link quality of the second Wi-Fi data link, max _ speed _ Wi-Fi _1 represents the maximum data transmission rate of the first Wi-Fi data link, and max _ speed _ Wi-Fi _2 represents the maximum data transmission rate of the second Wi-Fi data link. The sum of the link quality of the first Wi-Fi data link and the link quality of the second Wi-Fi data link is equal to 1.

Optionally, the maximum data transmission rate of the first Wi-Fi data link and the maximum data transmission rate of the second Wi-Fi data link may be modified by a data increment calculation rate of a Wi-Fi receive (rx) interface.

For example, data increment calculation rates on a first Wi-Fi receiving (rx) interface and a second Wi-Fi receiving (rx) interface are counted every 1s, and the maximum data transmission rate of the first Wi-Fi data link and the maximum data transmission rate of the second Wi-Fi data link are corrected through the data increment calculation rates.

tmp_speed＝(rx_bytes-last_rx_bytes)/1；

The modified max _ speed _ wi-fi _1 is max (max _ speed _ wi-fi _1, tmp _ speed);

the modified max _ speed _ wi-fi _2 is max (max _ speed _ wi-fi _2, tmp _ speed);

wherein rx _ bytes represents the data receiving amount on the first Wi-Fi interface and the second Wi-Fi interface within one second, last _ rx _ bytes represents the data receiving amount on the first Wi-Fi interface and the second Wi-Fi interface within the last second, tmp _ speed represents the data incremental calculation rate, max _ speed _ Wi-Fi _1 represents the maximum data transmission rate of the first Wi-Fi data link, and max _ speed _ Wi-Fi _2 represents the maximum data transmission rate of the second Wi-Fi data link. The modified max _ speed _ wi-fi _1 is the maximum value of the max _ speed _ wi-fi _1 and the tmp _ speed, and the modified max _ speed _ wi-fi _2 is the maximum value of the max _ speed _ wi-fi _2 and the tmp _ speed.

Optionally, the maximum data transmission rate of the first Wi-Fi data link and the maximum data transmission rate of the second Wi-Fi data link may be modified by a statistical Round-Trip Time (rtt).

For example, the mobile terminal may calculate the delay on the two interfaces (the first Wi-Fi module interface and the second Wi-Fi module interface) based on the rtt of the tcp itself, and one data link may calculate only the rtt of the first request after the three-way handshake, such as the rrt of the http get and the http post. The 3-way handshake refers to 3 acknowledgement procedures for TCP to establish a connection. The Transmission Control Protocol (tcp) counts rtt through a tcp _ rtt _ estimator () function to calculate a Retransmission Timeout (RTO), so that the delay calculation is calculated in the tcp _ rtt _ estimator () function.

The mobile terminal respectively determines a current first RTT of a first Wi-Fi data link and a current first RTT of a second Wi-Fi data link, and the method comprises the following steps:

the mobile terminal determines a second RTT for operating a Transmission Control Protocol (TCP);

the mobile terminal respectively acquires a third RTT determined last time by the first Wi-Fi module and the second Wi-Fi module;

and the mobile terminal determines the current first RTT of the first Wi-Fi module and the second Wi-Fi module based on the determined second RTT and the obtained third RTT which is determined last time by the first W-iFi module and the second Wi-Fi module.

Specifically, the following formula can be adopted to calculate the current first RTT of the first Wi-Fi data link and the current first RTT of the second Wi-Fi data link:

rtt_wi-fi_11＝(rtt_wi-fi_13+rtt_2)/2

rtt_wi-fi_21＝(rtt_wi-fi_23+rtt_2)/2

wherein, RTT _ Wi-Fi _11 represents a current first RTT of the first Wi-Fi data link, RTT _2 represents a second RTT of running a Transmission Control Protocol (TCP), and RTT _ Wi-Fi _13 represents a last determined third RTT of the first Wi-Fi data link; RTT _ Wi-Fi _21 represents a current first RTT of the second Wi-Fi data link, RTT _2 represents a second RTT of the second Wi-Fi data link running a transmission control protocol TCP, and RTT _ Wi-Fi _23 represents a last determined third RTT of the second Wi-Fi data link.

According to the embodiment of the application, the data transmission rate and the round trip delay are considered, and the calculation accuracy of the link quality of the first Wi-Fi data link and the link quality of the second WiFi data link can be improved.

In one possible example, before the mobile terminal detects a link quality of a first Wi-Fi data link and detects a link quality of a second Wi-Fi data link, the method further comprises:

the mobile terminal searches for available Wi-Fi hotspots around;

if the first Wi-Fi hotspot and the second Wi-Fi hotspot are searched to be available Wi-Fi hotspots, the mobile terminal respectively acquires working frequency bands of the first Wi-Fi hotspot and the second Wi-Fi hotspot;

if the working frequency bands of the first Wi-Fi hotspot and the second Wi-Fi hotspot do not belong to the same frequency band, the mobile terminal is connected with the first Wi-Fi hotspot and the second Wi-Fi hotspot to establish a first Wi-Fi data link and a second Wi-Fi data link.

Wherein, the Wi-Fi hotspot available refers to a hotspot through which a connection to a wireless network is possible.

The available Wi-Fi hotspots generally comprise 2.4G frequency band Wi-Fi hotspots and 5G frequency band Wi-Fi hotspots, and if the working frequency bands of the first Wi-Fi hotspot and the second Wi-Fi hotspot do not belong to the same frequency band, one of the first Wi-Fi hotspot and the second Wi-Fi hotspot is the 2.4G frequency band, and the other is the 5G frequency band. Because the mobile terminal comprises the first Wi-Fi module and the second Wi-Fi module, signals in two Wi-Fi frequency bands can be received and transmitted at the same time, the mobile terminal can be connected with two Wi-Fi hot spots in different frequency bands at the same time, and a Wi-Fi data link in the first frequency band and a Wi-Fi data link in the second frequency band are established.

The data packets transmitted in the first Wi-Fi data link need to pass through the first Wi-Fi hotspot, and the data packets transmitted in the second Wi-Fi data link need to pass through the second Wi-Fi hotspot.

Further, the method further comprises:

if the working frequency bands of the first Wi-Fi hotspot and the second Wi-Fi hotspot belong to the same frequency band, the mobile terminal determines whether the first Wi-Fi hotspot or the second Wi-Fi hotspot is a dual-frequency-band Wi-Fi hotspot;

if at least one of the first Wi-Fi hotspot and the second Wi-Fi hotspot is a dual-band Wi-Fi hotspot, the mobile terminal sends a frequency band switching instruction to one of the first Wi-Fi hotspot and the second Wi-Fi hotspot, wherein the frequency band switching instruction is used for switching the working frequency band of one of the first Wi-Fi hotspot and the second Wi-Fi hotspot;

and when the working frequency bands of the first Wi-Fi hotspot and the second Wi-Fi hotspot do not belong to the same frequency band, connecting the first Wi-Fi hotspot and the second Wi-Fi hotspot, and establishing a first Wi-Fi data link and a second Wi-Fi data link.

The dual-band Wi-Fi hotspot refers to a Wi-Fi hotspot supporting two frequency bands. A dual band Wi-Fi hotspot can switch between the two frequency bands.

Therefore, when the frequency bands of the two Wi-Fi hotspots connected with the mobile terminal belong to the same frequency band, in order to meet the requirement that the mobile terminal supports the function of aggregating the two Wi-Fi links, the working frequency band of one of the two Wi-Fi hotspots supporting the dual-frequency band Wi-Fi hotspot can be switched, the working frequency band of the dual-frequency band Wi-Fi hotspot connected with the mobile terminal can be intelligently switched, so that the requirement that the mobile terminal is connected with the two Wi-Fi hotspots of different frequency bands is met, and the function of aggregating the two Wi-Fi links is realized.

Step 202: the mobile terminal obtains a data packet to be transmitted, and determines transmission information between the first Wi-Fi data link and the second Wi-Fi data link based on the link quality of the first Wi-Fi data link, the link quality of the second Wi-Fi data link and the data packet to be transmitted.

In one possible example, the mobile terminal determining transmission information between the first Wi-Fi data link and the second Wi-Fi data link based on the link quality of the first Wi-Fi data link, the link quality of the second Wi-Fi data link, and the data packet to be transmitted includes:

the mobile terminal analyzes the data packet to be transmitted to obtain a plurality of first sub data packets;

if the link quality of the first Wi-Fi data link is greater than the link quality of the second Wi-Fi data link, the mobile terminal determines that the transmission information is that the first Wi-Fi data link is used for transmitting at least one first sub-packet i in the plurality of first sub-packets, and the second Wi-Fi data link is used for transmitting at least one first sub-packet j in the plurality of first sub-packets, wherein the size of the first sub-packet i is greater than that of the first sub-packet j.

Further, the method further comprises:

if the link quality of the first Wi-Fi data link is smaller than the link quality of the second Wi-Fi data link, the mobile terminal determines that the transmission information is at least one first sub-data packet i in the plurality of first sub-data packets transmitted by using the second Wi-Fi data link, and at least one first sub-data packet j in the plurality of first sub-data packets transmitted by using the first Wi-Fi data link, wherein the size of the first sub-data packet i is larger than that of the first sub-data packet j.

As can be seen, in this example, the mobile terminal transmits at least one first sub-packet i of the plurality of first sub-packets using the second Wi-Fi data link and transmits at least one first sub-packet j of the plurality of first sub-packets using the first Wi-Fi data link, and since the link quality of the second Wi-Fi data link is greater than that of the first Wi-Fi data link and the size of the first sub-packet i is greater than that of the first sub-packet j, the speed of data transmission can be increased.

In one possible example, the mobile terminal determines transmission information between the first Wi-Fi data link and the second Wi-Fi data link based on the link quality of the first Wi-Fi data link, the link quality of the second Wi-Fi data link, and the data packet to be transmitted, including:

the mobile terminal analyzes the data packet to be transmitted to obtain a plurality of second sub data packets;

if the link quality of the first Wi-Fi data link is smaller than the link quality of the second Wi-Fi data link, the mobile terminal determines that the transmission information is at least one second sub-packet p of the second sub-packets transmitted by using the second Wi-Fi data link, and at least one second sub-packet q of the second sub-packets transmitted by using the first Wi-Fi data link, where an importance degree of the second sub-packet p is greater than an importance degree of the second sub-packet q.

Further, the method further comprises:

if the link quality of the first Wi-Fi data link is greater than the link quality of the second Wi-Fi data link, the mobile terminal determines that the transmission information is at least one second sub-data packet p in the plurality of second sub-data packets transmitted by using the first Wi-Fi data link, and at least one second sub-data packet q in the plurality of second sub-data packets transmitted by using the second Wi-Fi data link, wherein the importance degree of the second sub-data packet p is greater than that of the second sub-data packet q.

As can be seen, in this example, the mobile terminal transmits at least one second subpacket p of the plurality of second subpackets by using the first Wi-Fi data link and transmits at least one second subpacket q of the plurality of second subpackets by using the second Wi-Fi data link, because the link quality of the second Wi-Fi data link is greater than that of the first Wi-Fi data link and the importance degree of the second subpacket p is greater than that of the second subpacket q, the data transmission speed is increased, and meanwhile, the security of important data packet transmission is increased to some extent.

the mobile terminal analyzes the data packet to be transmitted to obtain a plurality of third sub data packets;

if the link quality of the first Wi-Fi data link is greater than the link quality of the second Wi-Fi data link, the mobile terminal determines that the transmission information is that the first Wi-Fi data link is used for transmitting at least one third sub-packet m of the third sub-packets, and the second Wi-Fi data link is used for transmitting at least one third sub-packet n of the third sub-packets, wherein the real-time performance of the application corresponding to the third sub-packet m is higher than that of the application corresponding to the third sub-packet n.

Further, the method further comprises:

if the link quality of the first Wi-Fi data link is smaller than the link quality of the second Wi-Fi data link, the mobile terminal determines that the transmission information is that at least one third sub-data packet m in the multiple third sub-data packets is transmitted by using the second Wi-Fi data link, and at least one third sub-data packet n in the multiple third sub-data packets is transmitted by using the first Wi-Fi data link, wherein the real-time performance of the application corresponding to the third sub-data packet m is higher than that of the application corresponding to the third sub-data packet n.

As can be seen, in this example, the mobile terminal transmits at least one third sub-packet m of the plurality of third sub-packets using the first Wi-Fi data link and transmits at least one third sub-packet n of the plurality of third sub-packets using the second Wi-Fi data link, because the link quality of the first Wi-Fi data link is greater than the link quality of the second Wi-Fi data link and the real-time property of the application corresponding to the third sub-packet m is higher than the real-time property of the application corresponding to the third sub-packet n, not only the data transmission speed is increased, but also the internet experience of the user is improved.

if the data packet to be transmitted is a data packet of the video application, the mobile terminal determines a target segmentation proportion corresponding to the size of the data packet to be transmitted based on the mapping relation between the size of the data packet and the segmentation proportion;

the mobile terminal performs data packet segmentation operation on the data packet to be transmitted based on the target segmentation proportion to obtain a first buffer sub data packet and a second buffer sub data packet, wherein the playing time corresponding to the first buffer sub data packet is earlier than the playing time corresponding to the second buffer sub data packet;

if the link quality of the first Wi-Fi data link is smaller than the link quality of the second Wi-Fi data link, the mobile terminal determines that the transmission information is that the first buffer sub-data packet is transmitted by using the second Wi-Fi data link, and the second buffer sub-data packet is transmitted by using the first Wi-Fi data link.

Further, the method further comprises:

and if the link quality of the first Wi-Fi data link is greater than the link quality of the second Wi-Fi data link, the mobile terminal determines that the transmission information is that the first buffer sub-data packet is transmitted by using the first Wi-Fi data link and the second buffer sub-data packet is transmitted by using the second Wi-Fi data link.

As can be seen, in this example, the mobile terminal transmits the first buffered sub data packet using the second Wi-Fi data link and transmits the second buffered sub data packet using the first Wi-Fi data link, and since the link quality of the first Wi-Fi data link is smaller than the link quality of the second Wi-Fi data link and the playing time corresponding to the first buffered sub data packet is earlier than the playing time corresponding to the second buffered sub data packet, not only is the data transmission speed increased, but also the video experience of the user is improved.

In one possible example, after the mobile terminal obtains the data packet to be transmitted, the method further includes:

the mobile terminal acquires the current residual electric quantity of the mobile terminal;

the mobile terminal determines transmission information between the first Wi-Fi data link and the second Wi-Fi data link based on the link quality of the first Wi-Fi data link, the link quality of the second Wi-Fi data link and the data packet to be transmitted, and the method comprises the following steps:

the mobile terminal determines an initial data packet distribution ratio between the first Wi-Fi data link and the second Wi-Fi data link based on the link quality of the first Wi-Fi data link and the link quality of the second Wi-Fi data link;

if the residual electric quantity is smaller than a first threshold value, the size of the data packet to be transmitted is larger than or equal to a second threshold value, and the link quality of the first Wi-Fi data link is larger than that of the second Wi-Fi data link, the mobile terminal improves the initial data packet distribution proportion between the first Wi-Fi data link and the second Wi-Fi data link to obtain the data packet distribution proportion between the first Wi-Fi data link and the second Wi-Fi data link;

and the mobile terminal takes the proportion of the data packet distribution between the first Wi-Fi data link and the second Wi-Fi data link as the transmission information.

Further, the method further comprises:

if the residual electric quantity is smaller than a first threshold value, the size of a data packet to be transmitted is larger than or equal to a second threshold value, and the link quality of the first Wi-Fi data link is smaller than that of the second Wi-Fi data link, the mobile terminal reduces the initial data packet distribution proportion between the first Wi-Fi data link and the second Wi-Fi data link to obtain the data packet distribution proportion between the first Wi-Fi data link and the second Wi-Fi data link;

the mobile terminal takes the data packet distribution ratio between the first Wi-Fi data link and the second Wi-Fi data link as transmission information.

Step 203: and the mobile terminal transmits the data packet to be transmitted in the first Wi-Fi data link and the second Wi-Fi data link based on the transmission information.

The mobile terminal may send an uplink data packet and may also receive a downlink data packet. The data packet to be transmitted may be an uplink data packet or a downlink data packet. For uplink data packets, the mobile terminal may transmit the uplink data packets in the first Wi-Fi uplink and the second Wi-Fi uplink based on the transmission information; for downlink data packets, the mobile terminal may transmit the downlink data packets in the first Wi-Fi downlink and the second Wi-Fi downlink based on the transmission information.
