Referring to fig. 1, fig. 1 is a schematic diagram of a system frame of an electronic device according to an embodiment of the application. The data transmission method provided by the embodiment of the application is applied to electronic equipment, the electronic equipment supports the function of MPTCP (MultiPath Transmission Control Protocol, multiple transmission control protocol), the MPTCP is the expansion evolution of TCP, two communication parties are allowed to simultaneously establish a plurality of TCP links for data transmission, and when the two communication parties have a plurality of physical channels, the MPTCP realizes the concurrent transmission by simultaneously establishing TCP subflows on the plurality of physical channels. Different scheduling strategies are adopted on the MPTCP subflows to achieve different effects, an aggregate scheduling strategy is adopted to achieve high throughput, a redundant scheduling strategy is adopted to achieve low delay and high reliability. For example, an AP (wireless access point) of two hotspots is connected to a mobile phone through MPTCP at the same time.
In the prior art, some electronic devices have dual WiFi capability, so that multiple paths of dual WiFi exist between a mobile phone and a router, and the underlying support of multiple paths is provided for applying MPTCP, however, in the dual WiFi in the prior art, different TCP data streams are distributed to a primary WiFi or a secondary WiFi, and for a single data stream or a single WiFi, the single WiFi has the problems of large delay fluctuation and poor performance under interference. On the basis of double WiFi, if the capacity of MPTCP is expanded, one data stream can be transmitted on the double WiFi at the same time, and the link performance between the mobile phone and the router can be improved well.
In fig. 1, an electronic device 101 may be connected to a router 102 using WiFi, a technology that allows the electronic device to connect to a wireless local area network, typically using the 2.4G UHF or 5G SHF ISM radio frequency bands. The electronic device 101 may be connected to multiple routers 102 simultaneously through MPTCP, so that the electronic device may be connected to multiple radio access points through multiple transmission links, respectively, where the radio access points may also open a hotspot function for other electronic devices 103, such as the electronic device 103, to serve as one radio access point.
Referring to fig. 2, fig. 2 is a flow chart of a data transmission method according to an embodiment of the application. The data transmission method provided by the embodiment of the application is applied to the electronic equipment, and the specific flow can be as follows:
step 101, load information of a plurality of wireless access points currently connected with the electronic device is respectively obtained.
In the embodiment of the present application, the electronic device is respectively connected to a plurality of wireless access points through a multiplexing link, where the multiplexing link may be a TCP sub-stream that is simultaneously established on a plurality of physical channels by the electronic device through an MPTCP function, for example, two or more paths. For example, two transmission links are taken as an example, when a multiplexing link exists between the electronic device and the plurality of wireless access points, two transmission links may be selected from the multiplexing links to connect, where the two transmission links may be WiFi links, such as a 2.4G WiFi link and a 5G WiFi link, respectively, where the two wireless access points may have the same SSID (Service Set Identifier ) or may be different SSIDs. That is, the plurality of wireless access points currently connected to the electronic device include gateway devices connected through a local area network protocol and/or base station devices connected through a mobile communication protocol. Further, when two transmission links are selected from the multiple transmission links to connect with the corresponding radio access point, the selection may be performed according to the parameter information of the transmission links, such as delay, transmission rate, packet loss rate, and the like of the transmission links.
The wireless access point may be an AP providing a wireless network access service, a terminal device hotspot, or the like. The wireless network includes, but is not limited to, a wireless local area network based on IEEE802.11 series standard protocols, for example, a wireless local area network based on IEEE802.11n protocol, which is called a WiFi network, and the wireless device may access the corresponding wireless network through the wireless access point. In a subsequent embodiment of the invention, a wireless access point accessing a WiFi network is described as an example.
Further, after accessing to a plurality of wireless access points through a multiplexing link, load information of the plurality of wireless access points may be obtained, respectively. The load information may include a memory idle rate of each wireless access point, a CPU (Central Processing Unit ) idle rate, and the like.
In other embodiments, the load information may further include one or more of information of a current access device number, a maximum access device number, a current used bandwidth, a maximum bandwidth, and the like of each wireless access point. In the preferred embodiment of the invention, the wireless access point device can notify the electronic device of the information such as the current access device number, the maximum access device number, the current bandwidth, the maximum bandwidth and the like of the wireless access point device through the transmitted broadcast beacon frame and the probe response message of the response terminal.
The load information may include a wireless access device load rate, and specifically may be calculated according to the number of devices that have access to the wireless access point, that is, the formula: wireless access device load rate= (number of devices that have accessed the wireless access point/maximum number of devices that the wireless access point can access) ×100% is calculated. The load information may further include a wireless access bandwidth load rate, and specifically may be calculated according to current bandwidth information of the wireless access point, that is, a formula: wireless access bandwidth load rate= (current used bandwidth of wireless access point/maximum bandwidth of wireless access point) = 100% is calculated. Further, the load information may be obtained by performing comprehensive calculation according to the wireless access device load rate and the wireless access bandwidth load rate, for example, the wireless access device load rate obtained by performing calculation according to the number of devices accessed to the wireless access point and the wireless access bandwidth load rate obtained by performing calculation according to the current bandwidth information of the wireless access point are set with different weights, and weighted summation is obtained.
It should be noted that, the calculation of the wireless access device load rate and the wireless access bandwidth load rate may be performed by the wireless access point and then transmitted to the electronic device, or may be obtained by the electronic device by self-calculation after receiving the information such as the current access device number, the maximum access device number, the current usage bandwidth, the maximum bandwidth, and the like sent by the wireless access point. The information may even be obtained from the wireless access point by a server connected to the wireless access point and calculated and then sent to the electronic device, which is not particularly limited herein.
Preferably, the load information corresponding to the wireless access point may be periodically received by the electronic device from the wireless access point. The wireless access point periodically reports (e.g., once every 5 minutes, once every fifteen minutes, once every half hour, etc.) load information to the electronic device. The electronic device may store the load information in a database according to identification information (e.g., SSID) of the wireless access point. When the electronic equipment receives or generates a load information acquisition request, inquiring from a database according to the identification information of the wireless access point included in the load information acquisition request to obtain the load information corresponding to the wireless access point.
In an embodiment, a load threshold may be preset as a threshold value for normal operation of the radio access point. After the load information of the plurality of wireless access points currently connected is acquired, comparing the load information with the load threshold, and if the load information is smaller than the load threshold, further executing the subsequent steps. For example, if the electronic device is currently connected to two wireless access points, namely, a first wireless access point and a second wireless access point, through MPTCP, and the load rates of the two wireless access points are obtained and then compared with the load threshold, and if the load rate of the first wireless access point is smaller than the load threshold and the load rate of the second wireless access point is greater than the load threshold, the second wireless access point can be directly confirmed to be in an unavailable state currently, and at this time, the electronic device can only transmit data to the first wireless access point when transmitting data subsequently. If the load rates of the first wireless access point and the second wireless access point are both less than the load threshold, step 102 may be continued.
Step 102, obtaining data to be transmitted, and dividing the data to be transmitted into a plurality of sub-data according to the load information of a plurality of wireless access points.
In an embodiment, when the electronic device needs to transmit data, the data to be transmitted may be divided into a plurality of sub-data according to the load information of the plurality of wireless access points, so as to perform subsequent split transmission, thereby improving transmission efficiency. Before dividing the data to be transmitted, an application program corresponding to the data to be transmitted can be determined, then whether the application program is a preset application program or not is judged, the preset application program can be some application programs with higher importance degree installed in the electronic equipment, and if yes, the step of dividing the data to be transmitted is executed. Therefore, when the electronic equipment runs the preset application program and transmits application data, the transmission efficiency can be effectively improved through the shunt transmission scheme provided by the application. And aiming at other application programs with lower importance, data division and shunt transmission are not needed, so that equipment resources are saved. The preset application program may be preconfigured for the electronic device system, or may be set for the user, for example, the preset application program may be added or subtracted.
Further, considering that the foreground application program can be intuitively seen by the user in the process of using the electronic device, there is a higher requirement on the efficiency of data transmission. Therefore, the preset application program may be a foreground application program, after the data to be transmitted is obtained, it is determined whether the application program corresponding to the data to be transmitted is an application program, if yes, the step of dividing the data to be transmitted may be continuously performed.
In another embodiment, the data amount of the data to be transmitted may be further acquired and whether the data amount is greater than a preset value may be intelligently set by the electronic device system, for example, 200M, and if so, the data to be transmitted may be divided into a plurality of sub-data. For example, after the game application is opened, the game needs to update and download the 500M update package, and at this time, it is confirmed that the data size of the game data is greater than the preset value, and the transmission efficiency can be greatly improved by dividing the data and then performing split transmission.
In the embodiment of the application, the data to be transmitted can be divided into a plurality of sub-data according to the load information of a plurality of wireless access points, and particularly the data to be transmitted can be divided into a plurality of sub-data according to the proportion among the load rates of a plurality of wireless access points as the dividing basis, so that the sub-data with smaller data quantity can be transmitted through the wireless access point with higher load, and the sub-data with larger data quantity can be transmitted through the wireless access point with lower load.
For example, if the electronic device is currently connected to two wireless access points, namely, a first wireless access point and a second wireless access point, through MPTCP, the load rates of the two wireless access points are obtained to be 20% of the load rate of the first wireless access point and 80% of the load rate of the second wireless access point, and the ratio of the load rates is 2:8, at this time, the data to be transmitted can be divided into two sub-data according to the ratio, that is, the data size ratio of the divided two word data is also 2:8, for example, the data quantity to be transmitted is 100M, and sub data a of 20M and sub data B of 80M can be obtained through division.
Step 103, transmitting the plurality of sub-data to the plurality of wireless access points through multiplexing links, wherein the multiplexing links are in one-to-one correspondence with the plurality of wireless access points.
Continuing with the above example, after dividing 100M data to be transmitted into 20M sub data a and 80M sub data B, the sub data B may be transmitted to the first wireless access point, and the sub data a may be transmitted to the second wireless access point, so as to implement transmission of sub data with smaller data size through the wireless access point with higher load, and transmission of sub data with larger data size through the wireless access point with lower load. And the data to be transmitted are reasonably distributed according to the load conditions of a plurality of wireless access points, and split transmission is performed, so that the transmission efficiency is effectively improved.
In an embodiment, after the data to be transmitted is divided, a tag may be further added to the divided sub-data, where the tag may indicate a target wireless access point where the sub-data needs to be transmitted, for example, the tag may include an SSID of the target wireless access point.
As can be seen from the foregoing, in the data transmission method provided by the embodiment of the present application, a plurality of wireless access points may be connected through a multiplexing link, load information of the plurality of wireless access points currently connected may be obtained, data to be transmitted may be obtained, the data to be transmitted may be divided into a plurality of sub-data according to the load information of the plurality of wireless access points, and the plurality of sub-data may be transmitted to the corresponding wireless access points through the multiplexing link. The embodiment of the application can be connected with a plurality of wireless access points at the same time, and divides the network data according to the load conditions of the plurality of wireless access points and then distributes the network data for transmission so as to realize reasonable distribution of the transmitted network data.
The data transmission method of the present application will be further described based on the method described in the above embodiments. Referring to fig. 3, fig. 3 is another flow chart of a data transmission method according to an embodiment of the present application, where the data transmission method includes:
Step 201, load information of a plurality of wireless access points connected currently is obtained respectively, wherein the load information includes bandwidth occupancy rate of the wireless access points or number of devices accessed by the wireless access points.
In an embodiment, the electronic device is connected to the multiple radio access points through multiple transmission links, respectively, where the multiple transmission links may be TCP sub-streams that are simultaneously established on multiple physical channels by the electronic device through MPTCP function, for example, two or more paths. The wireless access point may be an AP providing a wireless network access service, a terminal device hotspot, or the like.
After accessing to a plurality of wireless access points through a multiplexing link, load information of the plurality of wireless access points can be acquired respectively. The load information may include a bandwidth occupancy of the wireless access point or the number of devices accessed by the wireless access point.
Further, the load information may further include current bandwidth used and maximum bandwidth information of each wireless access point, and then calculate the bandwidth occupancy rate of the wireless access point according to the current bandwidth used and the maximum bandwidth information. Of course, in other embodiments, the load information may also include a memory idle rate of each wireless access point, a CPU (Central Processing Unit ) idle rate, and the like.
Preferably, the load information corresponding to the wireless access point may be periodically received by the electronic device from the wireless access point. The wireless access point periodically reports (e.g., once every 5 minutes, once every fifteen minutes, once every half hour, etc.) load information to the electronic device.
Step 202, calculating a first ratio of bandwidth occupancy of each of the plurality of wireless access points or a number of devices accessed by the plurality of wireless access points.
In an embodiment, if the load information includes the currently used bandwidth and the maximum bandwidth information of the wireless access point, the bandwidth occupancy rate may be calculated according to the current bandwidth and the maximum bandwidth information. I.e. using the formula: bandwidth occupancy= (current used bandwidth of wireless access point/maximum bandwidth of wireless access point) ×100% is calculated. And then, respectively calculating the bandwidth occupancy rates of the wireless access points to obtain a first ratio among the bandwidth occupancy rates.
For example, if the electronic device is currently connected to two wireless access points, namely, a first wireless access point and a second wireless access point, through MPTCP, the bandwidth occupancy rates of the two wireless access points are obtained to be 20% of the bandwidth occupancy rate of the first wireless access point and 80% of the bandwidth occupancy rate of the second wireless access point, and the ratio of the bandwidth occupancy rates is 2:8.
In another embodiment, the first ratio may also be calculated according to the number of devices that each of the plurality of wireless access points accesses, for example, the number of access devices of the two wireless access points is 6 for the first wireless access point and 4 for the second wireless access point, where the ratio of the number of access devices is 6:4.
in step 203, a second proportion of the data to be transmitted to be divided is calculated according to the first proportion, and the data to be transmitted is divided into a plurality of sub-data according to the second proportion.
In an embodiment, the second ratio may be calculated according to the reciprocal of the first ratio, where the second ratio is a data dividing ratio, and the data to be transmitted is divided into a plurality of sub-data according to the second ratio. For example, if the bandwidth occupancy of each of the first wireless access point and the second wireless access point or the number of devices accessed by the plurality of wireless access points is a first ratio of 2:8, at this time, a second ratio of 8:2, the data to be transmitted can be divided into two sub-data according to the second proportion, for example, the data to be transmitted is 100M, and sub-data a of 80M and sub-data B of 20M can be obtained after division.
In an embodiment, the transmission quality of the plurality of wireless access points may be determined and scored according to load information, where the load information may include the bandwidth occupancy of the wireless access points and the number of accessed devices at the same time. For example, the lower the bandwidth occupancy, the fewer the number of access devices, indicating better communication quality, and the higher the quality score; the higher the bandwidth occupancy, the more the number of access devices, the worse the communication quality, and the lower the quality score. Then a first ratio between the quality scores of the plurality of wireless access points is obtained, and a second ratio of the divided sub-data is calculated.
In this embodiment, a radio access point with a higher quality score may be selected to transmit sub-data with a larger data size. If the quality score of the first wireless access point is higher than that of the second wireless access point, sub-data with larger divided data volume can be transmitted to the first wireless access point. If the quality score of the first wireless access point is lower than that of the second wireless access point, sub-data with larger divided data quantity can be transmitted to the second wireless access point. It can be appreciated that if the quality score of the first wireless access point is the same as the quality score of the second wireless access point, the data to be transmitted may be equally divided and randomly transmitted to the first wireless access point and the second wireless access point.
That is, in this embodiment of the application, the load information includes a bandwidth occupancy rate of the radio access point and the number of devices that are accessed, and the step of dividing the data to be transmitted into a plurality of sub-data according to the load information of the plurality of radio access points includes:
performing aggregation analysis on the bandwidth occupancy rate of the wireless access point and the number of the accessed devices, and calculating a quality score according to an analysis result;
calculating a first ratio of quality scores of the plurality of wireless access points;
and calculating a second proportion of the data to be transmitted, which is required to be divided, according to the first proportion, and dividing the data to be transmitted into a plurality of sub-data according to the second proportion.
In step 204, among the plurality of sub-data, the target wireless access point corresponding to each sub-data is determined according to the load information of the plurality of wireless access points.
In step 205, a mapping relationship between the sub-data and the corresponding target wireless access point is established.
In an embodiment, after the data to be transmitted is divided, a target wireless access point corresponding to the divided sub-data may be further determined according to load information of the wireless access point, where the target wireless access point may indicate the wireless access point to which the sub-data needs to be transmitted, and the target wireless access point may confirm through an SSID of the wireless access point. Then, a mapping relationship between the sub data and the SSID of the corresponding target wireless access point can be further established.
Step 206, determining target wireless access points corresponding to the plurality of sub-data according to the mapping relation.
Step 207, transmitting the sub-data through the transmission link corresponding to the target wireless access point.
For example, a first ratio of the first wireless access point to the second wireless access point is 2:8, then one can rely on 8:2 dividing the data to be transmitted, if the data to be transmitted is 100M, obtaining sub data a of 80M and sub data B of 20M after dividing, transmitting the sub data a to a first wireless access point, and transmitting the sub data B to a second wireless access point, so as to realize the transmission of the sub data with smaller data volume through the wireless access point with higher load and the transmission of the sub data with larger data volume through the wireless access point with lower load. And the data to be transmitted are reasonably distributed according to the load conditions of a plurality of wireless access points, and split transmission is performed, so that the transmission efficiency is effectively improved.
As can be seen from the foregoing, in the data transmission method provided in the embodiment of the present application, a plurality of wireless access points may be connected through a multiplex transmission link, load information of each of the plurality of wireless access points may be obtained, the load information includes a bandwidth occupancy rate of the wireless access point or a number of devices accessed by the wireless access point, a first ratio of a bandwidth occupancy rate of each of the plurality of wireless access points or a number of devices accessed by the plurality of wireless access points is calculated, a second ratio of data to be transmitted is calculated according to the first ratio, the data to be transmitted is divided into a plurality of sub-data according to the second ratio, among the plurality of sub-data, a mapping relationship between each sub-data and a corresponding target wireless access point is determined according to the load information of the plurality of wireless access points, the target wireless access points corresponding to the plurality of sub-data are respectively determined according to the mapping relationship, the sub-data are transmitted through the transmission link corresponding to the target wireless access points, and the data to be transmitted may be connected simultaneously, and the data to be divided into a plurality of sub-data according to the load conditions of the plurality of wireless access points, so that the network is reasonably transmitted after the data is divided.
