Referring to fig. 2A, fig. 2A is a schematic flowchart of a data transmission method, which is applied to an electronic device according to an embodiment of the present application; as shown in the figure, the data transmission method includes:
201. and starting a mobile data network of the electronic equipment after detecting that the electronic equipment and the automobile data recorder are connected through the Wi-Fi network.
The electronic equipment can suggest a Wi-Fi network between the electronic equipment and the automobile data recorder through the Wi-Fi module, and after the Wi-Fi network is established between the electronic equipment and the automobile data recorder, the mobile data network of the electronic equipment can be started. The mobile data network may be at least one of: 2G mobile data network, 3G mobile data network, 4G mobile data network and 5G mobile data network.
In a possible example, before the step 201, starting the mobile data network of the electronic device, the following steps may be further included:
and detecting whether the Wi-Fi network has an internet communication function, and if not, executing a step of starting a mobile data network of the electronic equipment.
The electronic equipment is provided with a Wi-Fi module which can be used for detecting whether the Wi-Fi can surf the internet or not, if the Wi-Fi module cannot surf the internet, the data network is pulled up, and the data network is set to be a default network (for example, the electronic equipment is an android system, the android system supports coexistence of multiple networks, and when the Wi-Fi is connected with a drive recorder, a networkRequest can be sent again to pull up the mobile data network.
Certainly, a policy route can be added to the inside of the default policy route table of the electronic device, so that all data packets to the Wi-Fi intranet IP address go out of the Wi-Fi, and it is ensured that the electronic device can view driving record images in the driving recorder through the Wi-Fi. For example, the policy routing table may have the following codes: from all to 10.174.59.103/28lookup main, which ensures the direct communication between the electronic device and the automobile data recorder (10.174.59.103 is the IP address of the Wi-Fi interface on the electronic device, 28 represents the subnet mask number of the IP address, 10.174.59.103/28 represents all the IP addresses in the same subnet as 10.174.59.103, the IP address of the automobile data recorder is also in the IP section; the rule represents that the destination IP addresses of all the data packets are in 10.174.59.103/28 subnet, and then the data packets are sent to the network From the Wi-Fi interface WLAN 0).
202. And carrying out first data transmission between the Wi-Fi network and the automobile data recorder.
The electronic equipment can perform first data transmission with the automobile data recorder through the Wi-Fi network, so that the control command is sent to the automobile data recorder, and the image data sent by the automobile data recorder is received.
203. And performing second data transmission between the mobile data network and the mobile network equipment.
The electronic device can realize second data output with the mobile network device through the mobile data network, that is, can realize an internet surfing function, for example, a WeChat and QQ instant chat function. Therefore, the network access function is realized through the mobile data network while the image data of the automobile data recorder is received through the Wi-Fi network. Of course, if the electronic device may also be a dual-card dual-standby device, the mobile data networks of two Subscriber Identity Modules (SIMs) may be started to obtain 2 mobile data network communication links, and the second data transmission is implemented by the 2 mobile data network communication links.
In a specific implementation, the step 202 and the step 203 may be executed in parallel, or may not be executed in a sequential order.
For example, the electronic device is a mobile phone, for example, when a user is in a car, the mobile phone may start a Wi-Fi function, and the automobile data recorder may serve as a hotspot, and if the mobile phone and the automobile data recorder establish a connection through a Wi-Fi network, at this time, the mobile phone may control the automobile data recorder through the Wi-Fi network, and may also receive a video sent by the automobile data recorder, and at this time, if the user wants to surf the internet (for example, send a WeChat message), the mobile phone in the prior art needs to close the Wi-Fi network and start the mobile data network to communicate.
For further example, when the data transmission rate between the mobile phone and the automobile data recorder is gradually decreased, for example, is lower than a certain threshold (e.g., the preset threshold described above), it indicates that it is highly likely that the video that the user needs to view is completely transmitted, the Wi-Fi network may be closed, for example, the Wi-Fi network of the mobile phone is closed, and of course, a closing instruction may also be sent to the automobile data recorder to instruct the automobile data recorder to also close the Wi-Fi network. For another example, after the Wi-Fi connection is established between the mobile phone and the automobile data recorder, the data transmission rate between the mobile phone and the automobile data recorder may be detected, and if the data transmission rate is always greater than a certain threshold (such as the preset threshold) within a period of time, it indicates that the Wi-Fi network is occupied, and the mobile data network of the mobile phone is automatically started, so as to ensure that the mobile phone can normally surf the internet.
For another example, in the driving process of the vehicle, the mobile phone receives the video sent by the automobile data recorder, analyzes the video, and automatically starts the mobile data network of the electronic device if a preset alarm picture (for example, a picture of other vehicles and objects (vehicles or pedestrians) being rubbed or touched, or a picture of pressing a solid line, or a picture of walking wrong ways) is analyzed, so that the user can report a case at the first time, or prompt the user, or inform family or friend. If the preset alarm picture is not analyzed, the mobile data network of the electronic equipment is not started, and after all, the user is easy to be distracted in the situation process, so that the user can drive the vehicle with the full mind. The preset alarm picture can be set by the user or the default of the system.
It can be seen that the data transmission method described in the embodiment of the application is applied to an electronic device, and after it is detected that the electronic device and an automobile data recorder are connected through a Wi-Fi network, a mobile data network of the electronic device is started, first data transmission is performed between the Wi-Fi network and the automobile data recorder, second data transmission is performed between the mobile data network and the mobile network device, it can be ensured that the electronic device can transmit images with the automobile data recorder through the Wi-Fi network, and meanwhile, an internet surfing function can be realized through the mobile data network.
In a possible example, before the step 201, starting the mobile data network of the electronic device, the following steps may be further included:
a1, detecting whether the data transmission rate between the electronic equipment and the automobile data recorder is greater than a preset threshold value;
a2, when the data transmission rate between the electronic equipment and the automobile data recorder is greater than the preset threshold value, executing the mobile data network for starting the electronic equipment;
a3, when the data transmission rate between the electronic equipment and the automobile data recorder is smaller than or equal to the preset threshold value, closing the Wi-Fi network.
The preset threshold value may be set by the user, or may be set by default. In specific implementation, the electronic device may detect a data transmission rate between the electronic device and the automobile data recorder, and when the data transmission rate is greater than a preset threshold, it indicates that the automobile data recorder transmits image data to the electronic device, and then, the mobile data network of the electronic device may be started.
In one possible example, the electronic device enables a plurality of mobile data network communication links, and the step 203 of performing the second data transmission with the mobile network device through the mobile data network may include the following steps:
31. acquiring a first data packet to be sent in the electronic equipment;
32. determining a first data flow to which the first data packet belongs;
33. detecting a link state of the first data flow, wherein the link state comprises a new state and an established state, the new state is used for indicating that a server does not respond to the first data flow, and the established state is used for indicating that the server responds to the first data flow;
34. when detecting that the link state of the first data stream is the new state, detecting whether the first data packet is sent for the first time; if the first data packet is detected to be sent for the first time, selecting a first mobile data network communication link in the multiple mobile data network communication links for the first data packet, and marking the first data packet according to a first link identification of the first mobile data network communication link; and selecting the network interface of the first mobile data network communication link according to the first link identification to send the first data packet.
The first data stream is a data stream in a first data stream set of the electronic device, the first data stream set is a data stream set in a plurality of data stream sets, and the data stream to which the data packet belongs is judged according to a ct pointer on the data packet. The new state is used for indicating that the server does not respond to the first data flow, which means that the electronic equipment sends a first message (SYN handshake signal) of the first data flow, but does not receive the reply of the server; the established state is used to indicate that the server has responded to the first data flow, which means that the electronic device sends a first message (SYN handshake signal) of the first data flow, the server replies to the electronic device, and the electronic device responds to the server again.
In addition, if the first data packet is sent for the first time, a first mobile data network communication link in the multiple mobile data network communication links is selected for the first data packet, then a link identifier is assigned to the first data packet, the first data packet is assigned to the ct pointer, and finally the first data packet is sent. For example, for a skb packet, the electronic device selects a first mobile data network communication link as Wi-Fi, and performs the following operations, namely skb- > mark, ct- > mark, skb-mark, and finally selects a network interface of the first mobile data network communication link according to the first link identifier to send the first packet.
It can be seen that, through the foregoing steps 31-34, in this embodiment of the present application, for a non-retransmitted data packet in a newly-established data stream, an electronic device can select a first mobile data network communication link from multiple mobile data network communication links for a first data packet, and mark the first data packet according to a link identifier of the first mobile data network communication link, so that a corresponding network interface can be directly enabled to send the first data packet according to the link identifier during subsequent sending, which avoids that transmission efficiency is affected due to link instability when all data packets are sent only through the same network interface, and is beneficial to improving data transmission efficiency of the electronic device.
As shown in fig. 2B, fig. 2B is a flowchart for implementing sending of a data packet at an electronic device based on a TCP/IP network architecture, where the data packet is sent from an application layer (Send), the data packet is sent to a network via a driver and a hardware layer, the application packet (Rev) is sent from the hardware layer to the driver layer, then to the TCP/IP network protocol stack, and then to the application layer, and is in a symmetric state, and the IP layer is nested with a linux kernelNetfilter firewall framework. All IP packets arriving at the TCP/IP protocol stack will pass through the Netfilter framework of the IP layer, and further, the original flow chart of the packets in the Netfilter framework is shown in fig. 2C, which is the Netfilter framework shown in fig. 2C, and there are 5 packet processing points, namely, forwarding, INPUT, FORWARD, OUTPUT, and post. And realizing packet sending and receiving of the data packet through the Netfilter framework, which is concretely as follows.
Specifically, the process of the package sending process is as follows: the application layer sends a data packet to a TCP layer, the TCP layer sends the data packet to an OUTPUT packet processing hook point of an IP layer through route judgment, then the data packet is sent to a POSTROUTING processing point, finally the data packet is sent to a mobile data network through a network card, the data packet needs to pass through a routing subsystem when being sent, the inquiry data needs to be sent to the network from which network interface, and at the moment, a strategy routing table can be inquired.
Specifically, the packet receiving processing procedure: after the network sends the data packet to the IP layer, the data packet is processed by a first processing point forwarding of the Netfilter framework and then is judged by the routing, whether the data packet is sent to the application layer for processing or forwarding is judged, and the electronic device basically sends the data packet to the application layer for processing, so the data packet needs to pass through the INPUT processing point and then is sent to the application layer.
In one possible example, the data transmission method includes: if the first data packet is detected not to be sent for the first time, a first mobile data network communication link for sending the first data packet for the first time is determined, a second link identification of a second mobile data network communication link is selected to mark the first data packet, a network interface of the second mobile data network communication link is selected according to the second link identification to send the first data packet, and the second mobile data network communication link is a mobile data network communication link except the first mobile data network communication link.
The condition that the electronic device detects that the first data packet is not sent for the first time means that the electronic device sends a first message (SYN handshake signal) to the server, but does not get a response from the server, which may be caused by poor channel quality of a first mobile data network communication link to which the first data packet belongs. In this case, the electronic device may select a mobile data network communication link other than the first mobile data network communication link according to a wireless module provided in the electronic device.
In this example, the electronic device can exclude the first mobile data network communication link used by the first data packet based on the wireless communication module of the electronic device, and select another mobile data network communication link to transmit data, thereby ensuring timeliness and efficiency of data transmission.
In one possible example, the data transmission method includes: and when the link state of the first data flow is detected to be the established state, marking the first data packet according to the link identification of the first data flow, and selecting a network interface of the adaptive mobile data network communication link according to the link identification of the first data packet to transmit the first data packet.
The established state refers to that when normal TCP network connection is established between the electronic equipment and the server, the electronic equipment firstly sends out a SYN message, the server uses SYN + ACK response to indicate that the message is received, and finally the electronic equipment responds with ACK message. Such that a reliable TCP connection can be established between the electronic device and the server and data can be transferred between the client and the server. And after judging whether the reliable connection is established or not, judging whether the first data packet is complete or not, and if the first data packet is incomplete or damaged, returning. If the first data packet is complete, the link ct pointer value is assigned to the first data packet. For example, for a complete skb data packet, the electronic device already establishes a normal connection with the server, and skb- > mark ═ ct- > mark processing is required when the data packet is sent.
Therefore, the judgment of the connection between the electronic equipment and the server and the judgment of whether the data packet is intact are carried out, the error transmission of data can be avoided, and the data transmission efficiency is improved.
In one possible example, the selecting a first mobile data network communication link of the plurality of mobile data network communication links for the first data packet comprises: querying a preset corresponding relation, and determining the first mobile data network communication link corresponding to the first data stream, where the corresponding relation includes a corresponding relation between a data stream and the plurality of mobile data network communication links, the data stream is a data stream of at least one data transmission task of the electronic device, each data transmission task is associated with an application started by the electronic device, and each data transmission task includes one or more data streams.
The preset corresponding relationship refers to a corresponding relationship previously set by a user or a corresponding relationship self-defined by an electronic equipment system. The user can use the one or more mobile data network communication links correspondingly according to the data transmission task type or quantity, and the user-defined corresponding relation of the electronic equipment system is that the electronic equipment outside the user setting preferentially selects the mobile data network communication link to be used. And then transmitting the data task according to the corresponding relation.
As can be seen, in this example, the first mobile data network communication link corresponding to the first data stream that needs to be transmitted by the electronic device may be set by a user or may be selected preferentially, so that the mobile data network communication link with poor channel quality can be avoided, and the transmission speed of data transmission is improved.
In one possible example, before obtaining the first data packet to be sent, the method further includes: and establishing the preset corresponding relation according to a preset data stream splitting strategy.
The data distribution strategy comprises the channel quality parameters of a mobile data network communication link and the like according to the data transmission task type.
Therefore, in this example, the electronic device performs shunt transmission on the data transmission task, and the stability and the transmission rate of the target data transmission task can be effectively improved.
In a possible example, the establishing the preset corresponding relationship according to a preset data stream splitting policy includes: determining a channel quality parameter for each of the plurality of mobile data network communication links, the channel quality parameters including transmission delay and rate; and dividing the data stream of the at least one data transmission task according to the channel quality parameter of the mobile data network communication link and the preset parameter of the data stream to obtain the preset corresponding relation.
The preset parameters of the data stream include data volume, type, importance degree and security of the data stream, wherein the security includes information such as payment and verification. The larger the data volume of the data stream is, the better the channel quality parameter of the mobile data network communication link which is matched with the data stream is; for the data stream with higher importance degree and higher security requirement, a mobile data network communication link with good channel quality parameters is selected to ensure accurate transmission of data.
As can be seen, in this example, the electronic device can determine the corresponding relationship between the data transmission task and the mobile data network communication link, and then perform data transmission according to the number of channels and the channel quality parameter of the wireless communication module. And the data stream of the at least one data transmission task is preferentially divided according to the channel quality parameters of the wireless communication module, so that the improvement of the data transmission speed and the safety of data transmission are ensured.
In a possible example, the establishing the preset corresponding relationship according to a preset data stream splitting policy includes: determining device capability information of a wireless communication module of the electronic device; and dividing the data stream of at least one data transmission task according to the equipment capability information and preset parameters of the data stream to obtain the preset corresponding relation.
The device capability information of the wireless communication module refers to parameters such as hardware parameters of the wireless communication module and channel capacity of wireless communication. In actual operation, for example, listening to music, uploading a big data file and the like, three adaptive wireless communication modules are selected according to three data transmission task types, and when the three adaptive wireless communication modules are selected, big data are matched with a high-quality channel to perform data transmission, and small data are matched with a poor channel to perform data transmission.
For the selection of the wireless communication module, the network charge is also considered, and a data transmission task of big data can be transmitted through Wi-Fi; data transmission tasks with smaller data volumes can be transmitted by LTE per flow charging.
Therefore, the electronic equipment can select the wireless communication module preferentially according to the capability information of the wireless communication module, can ensure that the transmission capability is matched with the transmission task, avoids waste, reduces the transmission speed, and ensures the low cost and the transmission efficiency of data transmission.
In one possible example, the preset parameter includes at least one of: data volume, type, priority; the priority includes any one of: importance level, task type level of the associated foreground, security level.
Therefore, in the example, the electronic device can preset parameters to perform data transmission on the data transmission task, and the improvement of the data transmission speed and the safety of the data transmission are ensured.
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.
