BRIEF DESCRIPTION OF DRAWINGS

[0023] Figure 1 Fig. 1 is a flowchart of an embodiment of the load balancing method for the Android system provided by the present application.

[0024] Figure 2 Fig. 2 is a structural schematic diagram of an embodiment of the load balancing device for the Android system provided by the present application. DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Embodiment one:

[0027] According to the related art, in a use scenario, the Android system can use the same WIFI module to realize a plurality of different functions at the same time. The functions include but are not limited to WLAN wireless connection function, WIFI direct connection function and hotspot sharing function and the like.

[0028] Due to certain user needs, it may be necessary to enable two or more functions simultaneously. For example, simultaneously enabling WLAN wireless connectivity and Wi-Fi Direct, or simultaneously enabling WLAN wireless connectivity and HOTSPOT sharing. However, the relevant technologies do not provide necessary restrictions on each function, which may lead to one function having excessive bandwidth, thus consuming the bandwidth of other functions. For instance, if the WLAN wireless connection function is 100 Mbit / s, but the total bandwidth is only 150 Mbit / s, then only 50 Mbit / s of bandwidth is available for the portable WLAN hotspot function, potentially resulting in low bandwidth for the portable WLAN hotspot function. Depending on actual usage requirements, random contention between functions may occur, thus affecting network stability and reliability.

[0029] Please refer to Figure 1 , Figure 1 This invention provides a load balancing method for an Android system to address one or more of the aforementioned technical problems, comprising steps S1 to S3, wherein...

[0030] Step S1: Enable the QoS configuration option through the kernel of the Android system source code.

[0031] In this embodiment, the Android system runs on a Linux kernel, which supports configurable and customizable features. This embodiment enables QoS configuration options through the Linux kernel.

[0032] QoS stands for Quality of Service. Network QoS, also known as network service quality, allocates bandwidth to various services / functions to provide quality assurance when bandwidth resources are limited. Through QoS configuration, you can define the priority of network transmission data, the allocation of network resources, and the control of network transmission characteristics.

[0033] Furthermore, before the Android system starts, the process also includes: cross-compiling the iproute2 source code to generate the corresponding executable file, and porting the executable file to the Android system.

[0034] Iproute2 source code is open source code and can be obtained from open source libraries. By cross-compiling this source code to obtain the corresponding executable file, the executable file can be ported to the Android system, thereby upgrading the executable program of the Android system.

[0035] Step S2: After the Android system starts up, it receives several function activation commands from the user; wherein each function activation command corresponds to a certain function of the WIFI module.

[0036] As an example of the embodiment, the several function start commands can include a first function start command, a second function start command and a third function start command. The functions of the WIFI module include WLAN wireless connection function, WIFI direct connection function and hotspot sharing function. At this time, the first function start command corresponds to the WLAN wireless connection function, the second function start command corresponds to the WIFI direct connection function, and the third function start command corresponds to the hotspot sharing function.

[0037] Step S3, in response to the function start command, according to the total bandwidth of the WIFI module of the Android system, respectively issuing a speed limit command to the network interface corresponding to each function to achieve load balancing of several functions; wherein the speed limit command includes the upper limit of the bandwidth corresponding to each function.

[0038] In the embodiment, preferably, the total bandwidth of the WIFI module of the Android system can be set according to the hardware performance parameters of the WIFI module.

[0039] In step S3, when the user needs to use a certain function, the Android system will receive a function start command corresponding to the certain function, and then, in response to the function start command and according to the total bandwidth of the WIFI module of the Android system, respectively issuing a speed limit command to the network interface corresponding to each function. For example, as an example of the embodiment, the command / system / bin / tc qdisc add dev WLAN0 root tbf rate 100Mbit latency 50ms burst 1000 can be used to achieve the above. The above command is a standard parameter input of the tc instruction. Among them, WLAN0 represents the network interface used by the wireless WLAN function, and 100M represents that the maximum bandwidth of the wireless WLAN function is 100M. Similarly, WLAN1 can be used to correspond to the network interface used by the hotspot function, and other commands can be used to correspond to the network interface of the WIFI direct connection function, and so on.

[0040] Further, by the same way of setting, on the premise that the total bandwidth is greater than or equal to 200Mbit / s, the WLAN wireless connection function is configured to limit the speed to 100Mbit / s, and the hotspot sharing function is configured to limit the speed to 100Mbit / s. When the user uses the WLAN wireless connection function, if the data volume of online reaches the set upper limit value, that is, 100Mbit / s, the function will not continue to occupy the bandwidth configured by the hotspot sharing function. At this time, both functions can guarantee to be allocated to 100Mbit / s of bandwidth, achieving the effect of load balancing.

[0041] As an example of the embodiment, the bandwidth upper limit of each function can be a preset value. As another example of the embodiment, the user can configure the corresponding speed limiting option of the setting page, so that the bandwidth of each function can be allocated.

[0042] Further, if the user does not want to limit the function (the reasons why the user does not want to limit the function include that the user wants to close the function or simply does not want to limit the bandwidth of the function to meet the maximum use requirement of the function), the function closing command of the user is received, and a speed limiting cancel command of the network interface of the function corresponding to the function closing command is issued in response to the function closing command, so as to close the bandwidth limitation of the function corresponding to the function closing command. For example, / system / bin / tc qdisc del dev WLAN0 root tbf, which is a parameter of the standard tc instruction, the WLAN0 parameter indicates the interface used by the WLAN wireless function, and after the configuration, the speed limitation of the WLAN wireless function takes effect. Correspondingly, the WIFI direct function and the hotspot sharing function can be respectively set in the same way.

[0043] In the embodiment, the reasonable allocation of the specific bandwidth can be considered according to the use scene of the device. For example, in general, the requirement of the bandwidth of the hotspot sharing (screen projection) function is higher than that of the ordinary online service, so when the hotspot is turned on, sufficient bandwidth is often guaranteed for the hotspot function, and when the hotspot function is turned off, the bandwidth limitation is turned off.

[0044] Correspondingly, referring to Figure 2 The embodiment of the application further provides a load balancing device for an Android system, which comprises a configuration module 101, a receiving module 102 and a speed limiting module 103.

[0045] The configuration module 101 is used for opening a QoS configuration option through the kernel of the source code of the Android system.

[0046] The receiving module 102 is used for receiving a plurality of function starting commands of the user after the Android system is started, wherein the function starting commands one by one correspond to a plurality of functions of the WIFI module.

[0047] The speed limiting module 103 is used for issuing a speed limiting command to the network interface corresponding to each function according to the total bandwidth of the WIFI module of the Android system in response to the function starting command, so as to realize the load balancing of the plurality of functions, wherein the speed limiting command comprises the bandwidth upper limit corresponding to each function.

[0048] As a preferred solution, the load balancing device further comprises a transplantation module for cross-compiling iproute2 source code, generating corresponding executable files, and transplanting the executable files into the Android system before the Android system is started.

[0049] As a preferred solution, the functions of the WIFI module include WLAN wireless connection function, WIFI direct connection function and hotspot sharing function.

[0050] As a preferred solution, the total bandwidth of the Android system WIFI module is set according to the hardware performance parameters of the WIFI module.

[0051] As a preferred solution, the load balancing device further comprises a speed limiting cancellation module for receiving a function closing command of a user, and issuing a speed limiting cancellation command to the network interface of the function corresponding to the function closing command to close the bandwidth limitation of the function corresponding to the function closing command in response to the function closing command.
