The following describes embodiments of the present application in detail.
Link aggregation refers to enabling a device to use two or more ports to access the internet at the same time, for example, a mobile phone uses Wi-Fi and LTE to access the network at the same time through link aggregation. an android network system, when Wi-Fi is enabled, may result in unavailability of a data network (connectivity Service network scoring mechanism results in disconnection of the data network), and link aggregation requires at least two or more available networks, so a prerequisite of a Service-Level Agreement (abbreviated as SLA) is to make Wi-Fi and the data network coexist. As shown in fig. 1, an electronic device 101 may be connected to a data network 103, which is a communication network for transmitting data traffic; Wi-Fi 102, a technology that allows an electronic device to connect to a wireless local area network, typically using the 2.4G UHF or 5G SHF ISM radio frequency bands; bluetooth 104, a wireless technology standard, may also be connected, enabling short-range data exchange (using UHF radio waves in the ISM band of 2.4-2.485 GHz) between fixed devices, mobile devices and building personal area networks, etc.
Referring to fig. 2A, fig. 2A is a schematic flowchart of a data transmission method applied to an electronic device according to an embodiment of the present application. The data transmission method comprises the following steps:
s201, the electronic equipment acquires a first data packet to be sent.
S202, when detecting that the first data packet is sent for the first time, the electronic device sends a first message to a server through a first wireless communication link in the multiple wireless communication links, and sends a second message to the server through a second wireless communication link, wherein the first message and the second message are synchronization sequence number (SYN) messages in a Transmission Control Protocol (TCP).
When sending a data packet to a network, the electronic device needs to acquire the right to access the network first, and after the three-way handshake of the transport layer is successful, the electronic device can send the first data packet to the server. In the prior art, an electronic device first sends a synchronization sequence number (SYN) message to a server through WIFI or a data network, and then sends an ACK message to the server when receiving the SYN and Acknowledgement Character (ACK) messages from the server, that is, three-way handshaking is completed, so that transmission of a data packet can be performed.
In the application, when it is detected that the first data packet is sent for the first time, a first message may be sent to the server through the first wireless communication link, and a second message may be sent to the server through the second wireless communication link, where the first message and the second message are SYN messages in a Transmission Control Protocol (TCP), and the first message may be copied to obtain the second message.
S203, when receiving a third packet from the server, the electronic device determines a wireless communication link corresponding to the third packet, and sends the first data packet through a network interface of the corresponding wireless communication link, where the third packet is used to indicate that the server receives the first packet or the second packet.
When the electronic device receives a third message from the server, that is, it indicates that the server receives the first message or the second message, the wireless communication link corresponding to the third message may be determined, and the first data packet is sent through the network interface of the corresponding wireless communication link, where the corresponding wireless communication link is the first wireless communication link or the second wireless communication link, and the third message is a SYN + ACK message in a transmission control protocol TCP.
For example, the corresponding wireless communication link is a first wireless communication link, which indicates that although the first wireless communication link and the second wireless communication link simultaneously transmit SYN messages to the server, the server transmits a third message through the first wireless communication link, that is, the server first receives the first message and responds to the electronic device, and the second wireless communication link may not successfully transmit the second message or has a slower transmission speed, so that the first wireless communication link may be more suitable for transmitting the first data packet than the second wireless communication link, and thus, the three-way handshake between the electronic device and the server may be continued through the first wireless communication link, and the first data packet may be transmitted through the first wireless communication link after the TCP connection is successfully established.
It can be seen that, in this embodiment of the application, an electronic device first obtains a first data packet to be sent, and then, when it is detected that the first data packet is sent for the first time, sends a first packet to a server through a first wireless communication link in a plurality of wireless communication links, and sends a second packet to the server through a second wireless communication link, where the first packet and the second packet are synchronization sequence number SYN packets in a transmission control protocol TCP, and finally, when a third packet from the server is received, determines a wireless communication link corresponding to the third packet, and sends the first data packet through a network interface of the corresponding wireless communication link, where the third packet is used to indicate that the server receives the first packet or the second packet. Because the electronic equipment can simultaneously send the first message to the server through the first wireless communication link and send the second message through the second wireless communication link, when receiving the third message from the server, the server can determine whether the first message or the second message is received first, so that the first wireless communication link or the second wireless communication link is selected to send the first data packet.
In one possible example, the determining a wireless communication link corresponding to the third packet and sending the first data packet through a network interface of the corresponding wireless communication link includes: determining that a wireless communication link for transmitting the third message is a first wireless communication link; marking the first data packet according to a first link identification of the first wireless communication link; and selecting a network interface of the first wireless communication link according to the first link identification to send the first data packet.
The server receives the first message sent by the first wireless communication link, and then replies a third message to the electronic device, or the server receives the second message sent by the second wireless communication link, and then replies the third message by the second wireless communication link.
If the wireless communication link for transmitting the third packet is determined to be the first wireless communication link, the first data packet may be sent after the network interface of the first wireless communication link is selected according to the first link identifier after the first data packet is marked according to the first link identifier of the first wireless link. The link identification is used to label the wireless communication link.
Wherein the server transmits the third message to the electronic device only through the first wireless communication link after receiving the first message transmitted through the first wireless communication link, thereby responding to the first message without any response even when receiving the second message transmitted through the second wireless communication link.
As can be seen, in this example, after receiving the third packet sent by the server through the first wireless communication link, the electronic device completes the second handshake in the TCP protocol, so that it can be determined that the data transmission quality of the first wireless communication link is better than that of the second wireless communication link.
In one possible example, the determining a wireless communication link corresponding to the third packet and sending the first data packet through a network interface of the corresponding wireless communication link includes: determining a wireless communication link for transmitting the third message as a second wireless communication link; marking the first data packet according to a second link identification of the second wireless communication link; and selecting the network interface of the second wireless communication link according to the second link identification to send the first data packet.
If the wireless communication link for transmitting the third packet is determined to be the second wireless communication link, the first data packet may be sent after the network interface of the second wireless communication link is selected according to the second link identifier after the first data packet is marked according to the second link identifier of the second wireless link.
Wherein the server transmits the third message to the electronic device only through the second wireless communication link after receiving the first message transmitted through the second wireless communication link, thereby responding to the first message without any response even if the first message transmitted through the first wireless communication link is received.
As can be seen, in this example, after receiving the third packet sent by the server through the second wireless communication link, the electronic device completes the second handshake in the TCP protocol, so that it can be determined that the data transmission quality of the second wireless communication link is better than the data transmission quality of the first wireless communication link.
In one possible example, after determining the wireless communication link corresponding to the third packet, the method further includes: sending a fourth message to the server through the corresponding wireless communication link, wherein the fourth message is used for indicating the electronic equipment to receive the third message; and after the server receives the fourth message, determining to transmit the first data packet through the network interface of the corresponding wireless communication link.
After the wireless communication link corresponding to the third message is determined, the electronic device also sends a fourth message to the server through the corresponding wireless communication link, so that the server is informed of receiving the third message sent by the server, at this time, three-way handshake in the TCP protocol is completed, and the electronic device can access the server through the corresponding wireless communication link.
For example, as shown in fig. 2B, the electronic device simultaneously sends a first message and a second message to the server through the first wireless communication link and the second wireless communication link, the server sends a third message to the electronic device through the first wireless communication link after receiving the first message, and the electronic device sends a fourth message to the server through the first wireless communication link after receiving the third message, so that three-way handshake is completed.
As can be seen, in this example, the electronic device sends the fourth packet to the server through the wireless communication link corresponding to the third packet, so that three-way handshake in the TCP protocol is completed, and after the server receives the fourth packet, it is determined that the first data packet is sent through the network interface of the corresponding wireless communication link.
In one possible example, the method further comprises: if the first data packet is detected not to be sent for the first time, acquiring a link identification of the first data packet; when the link identification is detected to be a first link identification, determining that a wireless communication link for sending the first data packet for the first time is a first wireless communication link; and selecting a second link identification of a second wireless communication link to mark the first data packet, and selecting a network interface of the second wireless communication link to send the first data packet according to the second link identification, wherein the second wireless communication link is a wireless communication link except the first wireless communication link.
The situation that the electronic device detects that the first data packet is not sent for the first time means that the electronic device sends a SYN message to the server, but does not get a response from the server, which may be caused by poor channel quality of a wireless communication link sending the first data packet for the first time. In this case, the electronic device may select a wireless communication link other than the wireless communication link according to a wireless module provided in the electronic device.
The link identifier of the first data packet is obtained, when the link identifier is detected to be the first link identifier, it is determined that the first data packet is transmitted for the first time through the first wireless communication link, at this time, a second link identifier of a second wireless communication link needs to be selected to mark the first data packet, and the first data packet is transmitted through the second wireless communication link, where the second wireless communication link is a wireless communication link other than the first wireless communication link.
In this example, after the first data packet is failed to be transmitted through the first wireless communication link, the second wireless communication link is selected to transmit the first data packet, the second link identifier of the second wireless communication link is selected to mark the first data packet, and the network interface of the second wireless communication link is selected according to the second link identifier to transmit the first data packet, so that the success rate of data transmission can be improved.
In one possible example, the first communication link is a WIFI wireless communication link and the second communication link is a long term evolution LTE wireless communication link.
It can be seen that, in this example, when electronic device and server handshake for the first time, WIFI wireless communication link and LTE wireless communication link can handshake for the first time simultaneously, and through the preferred link, confirm that it transmits first data packet through which communication link, be favorable to improving data transmission's stability.
In one possible example, the first data packet is a data packet generated by the local terminal of the electronic device; or, the first data packet is a data packet to be forwarded and received by the electronic device.
Therefore, the electronic equipment can not only transmit the data packet generated by the equipment, but also forward the data packet, so that the diversity of data transmission tasks is ensured.
Referring to fig. 3, fig. 3 is a schematic flowchart of a data transmission method according to an embodiment of the present application, and the method is applied to an electronic device, where the electronic device enables multiple wireless communication links. As shown in the figure, the data transmission method includes:

S303, when receiving a third packet from the server, the electronic device determines that a wireless communication link transmitting the third packet is a first wireless communication link, where the third packet is used to indicate that the server receives the first packet or the second packet.
S304, the electronic device marks the first data packet according to the first link identification of the first wireless communication link.
S305, the electronic device selects a network interface of the first wireless communication link according to the first link identifier to send the first data packet.
