In the description that follows, specific embodiments of the present application will be described with reference to steps and symbols executed by one or more computers, unless otherwise indicated. Accordingly, these steps and operations will be referred to, several times, as being performed by a computer, the computer performing operations involving a processing unit of the computer in electronic signals representing data in a structured form. This operation transforms the data or maintains it at locations in the computer's memory system, which may be reconfigured or otherwise altered in a manner well known to those skilled in the art. The data maintains a data structure that is a physical location of the memory that has particular characteristics defined by the data format. However, while the principles of the application have been described in language specific to above, it is not intended to be limited to the specific form set forth herein, and it will be recognized by those of ordinary skill in the art that various of the steps and operations described below may be implemented in hardware.
The terms "first", "second", and "third", etc. in this application are used to distinguish between different objects and not to describe a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to only those steps or modules listed, but rather, some embodiments may include other steps or modules not listed or inherent to such process, method, article, or apparatus.
Referring to fig. 1, fig. 1 is a schematic diagram of a system framework of an electronic device according to an embodiment of the present disclosure. The data Transmission method provided by the embodiment of the application is applied to an electronic device, the electronic device supports an MPTCP (multi path Transmission Control Protocol) function, the MPTCP is an extended evolution of the TCP, allows two communication parties to establish a plurality of TCP links for data Transmission at the same time, and when the two communication parties have a plurality of physical channels, the MPTCP realizes concurrent Transmission by establishing TCP subflows on the plurality of physical channels at the same time. Different scheduling strategies are adopted on the MPTCP substreams to realize different effects, an aggregation scheduling strategy is adopted to realize high throughput, and a redundancy scheduling strategy is adopted to realize low delay and high reliability. For example, a mobile phone is simultaneously connected to two APs (wireless access points) of a hot spot through MPTCP.
In the prior art, some electronic devices have dual-WiFi capability, so that multipath of dual-WiFi exists between a mobile phone and a router, and provides a bottom layer support of multipath for applying MPTCP, however, dual-WiFi in the prior art allocates different TCP data streams to main WiFi or secondary WiFi, and for a single data stream or single WiFi, single WiFi has a problem of large time delay fluctuation and poor performance under interference. On the basis of the double WiFi, if the capacity of the 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 well improved.
In fig. 1, anelectronic device 101 may connect to arouter 102 to use 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. Theelectronic device 101 may be simultaneously connected to the plurality ofrouters 102 through MPTCP, so that the electronic device is respectively connected to the plurality of wireless access points through multiple transmission links, where the wireless access points may also open a hot spot function for otherelectronic devices 103, such as theelectronic device 103, to serve as a wireless access point.
Referring to fig. 2, fig. 2 is a schematic flowchart of a data transmission method according to an embodiment of the present disclosure. 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:
In this embodiment, the electronic device is respectively connected to the multiple wireless access points through multiple transmission links, where the multiple transmission links may be TCP sub-streams, such as two or more TCP sub-streams, that are simultaneously established on multiple physical channels by the electronic device through an MPTCP function. For example, two transmission links are taken as an example to describe, when multiple transmission links exist between the electronic device and multiple wireless access points, two transmission links may be selected from the multiple transmission links to connect, where the two transmission links may be WiFi links, such as 2.4G WiFi links and 5G WiFi links, respectively, and the two wireless access points may have the same SSID (Service Set Identifier) or different SSIDs. That is, the plurality of wireless access points to which the electronic device is currently connected includes a gateway device connected through a local area network protocol and/or a base station device connected through a mobile communication protocol. Further, when two transmission links are selected from the multiple transmission links to connect with the corresponding wireless access point, the selection may be performed according to 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 known as a WiFi network, and a wireless device can access the corresponding wireless network through the wireless access point. In the subsequent embodiments of the present invention, a description is given by taking a wireless access point accessing a WiFi network as an example.
Further, after accessing to a plurality of wireless access points through a multi-transmission link, the load information of the plurality of wireless access points can be acquired respectively. The load information may include a memory idle rate, a CPU (Central Processing Unit) idle rate, and the like of each wireless access point.
In other embodiments, the load information may further include one or more of information of a current number of access devices, a maximum number of access devices, a current used bandwidth, a maximum bandwidth, and the like of each wireless access point. In the preferred embodiment of the present invention, the wireless access point device may notify the electronic device of information such as the current number of access devices, the maximum number of access devices, the current usage bandwidth, the maximum bandwidth, and the like, 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 may specifically be calculated according to the number of devices that have accessed the wireless access point, that is, using a formula: the radio access device load rate (the number of devices that have accessed the radio access point/the maximum number of devices that can be accessed by the radio access point) × 100% is calculated. The load information may further include a wireless access bandwidth load rate, and specifically, the load information may be calculated according to current bandwidth information of the wireless access point, that is, using a formula: the radio access bandwidth load rate (current used bandwidth of the radio access point/maximum bandwidth of the radio access point) × 100% is calculated. Further, the load information may also be obtained by performing comprehensive calculation according to the load rate of the wireless access device and the load rate of the wireless access bandwidth, for example, setting different weights according to the load rate of the wireless access device calculated according to the number of devices that have accessed the wireless access point and the load rate of the wireless access bandwidth calculated according to the current bandwidth information of the wireless access point, and performing weighted summation to obtain the load information.
It should be noted that, the calculation of the load rate of the wireless access device and the load rate of the wireless access bandwidth may be performed by the wireless access point and then transmitted to the electronic device, or may be calculated by the electronic device after receiving information such as the current number of access devices, the maximum number of access devices, the current usage bandwidth, and the maximum bandwidth sent by the wireless access point. Even the server connected to the wireless access point may obtain the information from the wireless access point, calculate the information, and send the information to the electronic device, which is not limited in this respect.
Preferably, the load information corresponding to the wireless access point may be periodically received from the wireless access point by the electronic device. The wireless access point reports load information to the electronic device periodically (e.g., once every 5 minutes, once every fifteen minutes, once every half hour, etc.). The electronic device may store the load information in a database according to identification information (such as SSID) of the wireless access point. When the electronic equipment receives or generates a load information acquisition request, the load information corresponding to the wireless access point is obtained by inquiring a database according to the identification information of the wireless access point included in the load information acquisition request.
In an embodiment, a load threshold may be preset to be a critical value for the normal operation of the wireless access point. And comparing the obtained load information of the plurality of currently connected wireless access points with the load threshold, and if the obtained load information is smaller than the load threshold, further executing the subsequent steps. For example, if the electronic device is currently connected with 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 and then compared with the load threshold, 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 determined to be in an unavailable state, and at this time, the electronic device can only transmit data to the first wireless access point during subsequent data transmission. 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.
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, determining an application program corresponding to the data to be transmitted, and then judging whether the application program is a preset application program, wherein the preset application program can be some application programs with higher importance degree installed in the electronic equipment, and if so, executing the step of dividing the data to be transmitted. Therefore, the transmission efficiency can be effectively improved through the shunt transmission scheme provided by the application when the electronic equipment runs the preset application program and transmits the application data. And for other application programs with lower importance degrees, data division and shunt transmission are not needed, and equipment resources are saved. The preset application program may be configured in advance for the electronic device system, or may be set by the user himself, for example, the preset application program is added or deleted.
Further, considering that the foreground application is directly viewable by the user during the use of the electronic device, there is a higher demand for the efficiency of data transmission. Therefore, the preset application program can also be a foreground application program, after the data to be transmitted is obtained, whether the application program corresponding to the data to be transmitted is the application program is judged, and if yes, the step of dividing the data to be transmitted can be continuously executed.
In another embodiment, the data size of the data to be transmitted may be further obtained, and whether the data size is greater than a preset value is determined, where the preset value may be intelligently set by an electronic device system, for example, 200M, and if the data size is greater than the preset value, the data to be transmitted may be divided into a plurality of sub-data. For example, after a game application is opened, a game needs to update and download a 500M update package, and at this time, it is determined that the data volume of the game data is greater than a preset value, and then 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 subdata according to the load information of the plurality of wireless access points, and the data to be transmitted can be divided into a plurality of subdata according to the division basis of the ratio of the load rates of the plurality of wireless access points, so that the subdata with smaller data volume can be transmitted through the wireless access points with higher load, and the subdata with larger data volume can be transmitted through the wireless access points 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 obtained load rates of the two wireless access points are respectively 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: at this time, the data to be transmitted may also be divided into two subdata according to the ratio, that is, the ratio of the data amount of the divided two word data is also 2: for example, if the amount of data to be transmitted is 100M, 20M of sub-data a and 80M of sub-data B can be obtained through division.
And 103, respectively transmitting the plurality of subdata to a plurality of wireless access points through a plurality of transmission links, wherein the plurality of transmission links correspond to the plurality of wireless access points one to one.
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 transmit sub-data with a smaller data amount through the wireless access point with a higher load, and transmit sub-data with a larger data amount through the wireless access point with a lower load. Data to be transmitted are reasonably distributed according to the load conditions of the wireless access points, and are transmitted in a shunting manner, 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 to which the sub-data needs to be transmitted, and for example, the tag may include an SSID of the target wireless access point.
As can be seen from the above, the data transmission method provided in the embodiment of the present application may respectively connect to a plurality of wireless access points through a multi-path transmission link, respectively obtain load information of the plurality of wireless access points currently connected, respectively obtain data to be transmitted, divide the data to be transmitted into a plurality of sub-data according to the load information of the plurality of wireless access points, and respectively transmit the plurality of sub-data to corresponding wireless access points through the multi-path transmission link. The embodiment of the application can be simultaneously connected with a plurality of wireless access points, and divides and then distributes the transmission of the network data according to the load conditions of the plurality of wireless access points so as to realize reasonable distribution of the transmitted network data.
The data transmission method of the present application will be further described below on the basis of the methods described in the above embodiments. Referring to fig. 3, fig. 3 is another schematic flow chart of a data transmission method according to an embodiment of the present application, where the data transmission method includes:
In an embodiment, the electronic device is connected to the plurality of wireless access points respectively through a plurality of transmission links, where the plurality of transmission links may be TCP sub-streams, such as two or more TCP sub-streams, that are simultaneously established on a plurality of physical channels by the electronic device through the MPTCP function. 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 multiplex transmission link, the load information of the plurality of wireless access points can be respectively obtained. The load information may include a bandwidth occupancy of the wireless access point or a number of devices accessed by the wireless access point.
Further, the load information may further include information of a currently used bandwidth and a maximum bandwidth of each wireless access point, and then the bandwidth occupancy rate of the wireless access point is calculated. Of course, in other embodiments, the load information may also include a memory idle rate, a CPU (Central Processing Unit) idle rate, and the like of each wireless access point.
Preferably, the load information corresponding to the wireless access point may be periodically received from the wireless access point by the electronic device. The wireless access point reports load information to the electronic device periodically (e.g., once every 5 minutes, once every fifteen minutes, once every half hour, etc.).
In an embodiment, if the load information includes information of a currently used bandwidth and a maximum bandwidth of the wireless access point, the bandwidth occupancy may be calculated accordingly. I.e. using the formula: bandwidth occupancy is calculated as (current used bandwidth of wireless access point/maximum bandwidth of wireless access point) × 100%. And then respectively calculating the respective bandwidth occupancy rates of the plurality of wireless access points to obtain a first proportion among the plurality of bandwidth occupancy rates.
For example, if the electronic device currently connects 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 respectively obtained as the bandwidth occupancy rate of the first wireless access point being 20% and the bandwidth occupancy rate of the second wireless access point being 80%, 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 accessed by each of the multiple wireless access points, 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, respectively, and the ratio of the number of access devices is 6: 4.
In an embodiment, a second ratio, which is a data dividing ratio, may be calculated according to a reciprocal of the first 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 rate of each of the first wireless access point and the second wireless access point or the first ratio of the number of devices accessed by the multiple wireless access points is 2: 8, calculating a second ratio of 8: 2, the data to be transmitted may also be divided into two sub-data according to the second ratio, for example, the data amount to be transmitted is 100M, and then 80M sub-data a and 20M sub-data B may be obtained through division.
In an embodiment, the transmission quality of the multiple wireless access points may be determined and scored according to load information, where the load information may include both the bandwidth occupancy of the wireless access points and the number of devices accessed. For example, the lower the bandwidth occupancy rate, the smaller the number of access devices, the better the communication quality is, and at this time, the higher the quality score is; the higher the bandwidth occupancy rate, the more access devices, the worse the communication quality, and the lower the quality score. Then, a first ratio among the quality scores of the plurality of wireless access points is obtained, and a second ratio for dividing the sub-data is calculated.
In this embodiment, the wireless access point with a higher quality score may be selected to transmit the sub data with a larger data size. For example, if the quality score of the first wireless access point is higher than the quality score of the second wireless access point, the sub data with a larger divided data amount may 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, the sub data with larger divided data volume can be transmitted to the second wireless access point. It can be understood 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 application embodiment, the load information includes the bandwidth occupancy rate of the wireless access point and the number of devices 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 wireless 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 needs to be divided, according to the first proportion, and dividing the data to be transmitted into a plurality of subdata according to the second proportion.
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 a wireless access point to which the sub-data needs to be transmitted, and the target wireless access point may perform confirmation through an SSID of the wireless access point. Then, the mapping relation between the subdata and the SSID of the corresponding target wireless access point can be further established.
And step 206, respectively determining the target wireless access points corresponding to the plurality of subdata according to the mapping relation.
And step 207, transmitting the sub data through the transmission link corresponding to the target wireless access point.
For example, the first ratio of the first wireless access point to the second wireless access point is 2: 8, then the data can be obtained from 8: and 2, dividing the data to be transmitted, if the data to be transmitted is 100M, obtaining 80M subdata A and 20M subdata B after division, transmitting the subdata A to the first wireless access point, and transmitting the subdata B to the second wireless access point, so that the subdata with smaller data volume is transmitted through the wireless access point with higher load, and the subdata with larger data volume is transmitted through the wireless access point with lower load. Data to be transmitted are reasonably distributed according to the load conditions of the wireless access points, and are transmitted in a shunting manner, so that the transmission efficiency is effectively improved.
As can be seen from the above, the data transmission method provided in this embodiment of the present application may respectively connect to multiple wireless access points through multiple transmission links, respectively obtain load information of the multiple wireless access points currently connected, where the load information includes bandwidth occupancy of the wireless access points or the number of devices accessed by the wireless access points, calculate a first ratio of the bandwidth occupancy of each of the multiple wireless access points or the number of devices accessed by the multiple wireless access points, calculate a second ratio of the data to be transmitted that needs to be divided according to the first ratio, divide the data to be transmitted into multiple sub-data according to the second ratio, among the multiple sub-data, respectively determine a target wireless access point corresponding to each sub-data according to the load information of the multiple wireless access points, and establish a mapping relationship between the sub-data and the corresponding target wireless access point, the method comprises the steps of respectively determining target wireless access points corresponding to a plurality of subdata according to the mapping relation, and transmitting the subdata through transmission links corresponding to the target wireless access points.
