In order to facilitate understanding of the inventive solution, a brief description of the hardware basis on which the inventive solution is implemented follows.
Referring to fig. 4, corresponding to the logical hierarchy of the android system, the Wi-Fi module 102 of the mobile terminal includes a Wi-Fi chip 1021, a Wi-Fi dual-port driver module 1022, a Wi-Fi dual-port protocol module 1023, a Wi-Fi dual-port frame module 1024, and a display module 1025.
The Wi-Fi chip 1021 supports a double-MAC technology, can burn two different MAC addresses at the same time, and is responsible for realizing data communication of the bottommost layer.
On the basis that the existing Wi-Fi drive only supports the wlan0, the Wi-Fi dual-port drive module 1022 additionally supports the wlan1, binds two MAC addresses with the wlan0 and the wlan1 respectively, and builds a communication channel to ensure that a drive command can be smoothly sent to the Wi-Fi chip 1021.
The Wi-Fi dual-port protocol module 1023 comprises two protocol stacks, which are respectively used for supporting a port wlan0 and a port wlan1, and contain relatively independent configuration files for storing wireless hotspot information and protocol stack configuration information. The information in the two ports wlan0 and wlan1 can be synchronized through separate services in the protocol stacks, so that the operation of a user on any one path can be stored, and in the process of starting Wi-Fi, when the protocol stacks are started, the protocol stacks of the two ports can be respectively started, and meanwhile, the Wi-Fi dual-port driving module 1022 can be notified to enable the two ports, and after the two wlan ports at the bottom layer are enabled, the bottom layer driving part and the following parts really have the double Wi-Fi functions. The Wi-Fi dual port protocol module 1023 completes the binding of the protocol stack and the bottom port through the common interface provided by the Wi-Fi dual port driver module 1022, and further completes the establishment of the message channel.
The Wi-Fi dual-port frame module 1024 is different from the original single Wi-Fi frame in that the support for a wlan1 port is newly added, the original Wi-Fi frame and a message mechanism are kept unchanged, a set of new message transmission mechanism is independently established, two sockets are simultaneously started to bind different protocol stacks, and normal communication of an upper layer and a lower layer is kept. The Wi-Fi dual port frame module 1024 distinguishes whether the issued command belongs to wlan0 or wlan1 by port number.
And the display module 1025 is used for displaying the user interface, receiving the triggered user interface operation and responding by other corresponding modules.
Based on the above description regarding the mobile terminal Wi-Fi module 102, the following describes in detail the implementation of the solution of the present invention.
In this embodiment, the Wi-Fi module 102 further includes a first Wi-Fi antenna and a second Wi-Fi antenna, and the Wi-Fi module 102 can connect to the two wireless hotspots through the first Wi-Fi antenna and the second Wi-Fi antenna at the same time. By default, referring to fig. 5, after the Wi-Fi module 102 establishes a connection with a first wireless hotspot working in a first frequency band through a first Wi-Fi antenna based on a first MAC address, the Wi-Fi module 102 establishes a connection with a second wireless hotspot working in a second frequency band through a second Wi-Fi antenna based on a second MAC address. When the first wireless hotspot works in the 2.4G frequency band, the second wireless hotspot works in the 5G frequency band, or when the first wireless hotspot works in the 5G frequency band, the second wireless hotspot works in the 2.4G frequency band. For example, after establishing a connection with a wireless hotspot operating in a 2.4G frequency band, the Wi-Fi module 102 of the mobile terminal defaults to establish a connection with another wireless hotspot operating in a 5G frequency band. It should be noted that, in other embodiments, the Wi-Fi module 102 of the mobile terminal may simultaneously connect two wireless hotspots operating in the 2.4G frequency band, and may also simultaneously connect two wireless hotspots operating in the 5G frequency band.
In real life, various public places usually provide free wireless access services, however, it is likely that these wireless hotspots providing free wireless access services are set by lawless persons for stealing user privacy data, for example, lawless persons usually set a wireless hotspot without password verification to induce a user to connect a mobile terminal to the wireless hotspot, and then background capture the user's account information, chat information and other privacy data.
In order to avoid the above situation, when the mobile terminal starts the application program, the mobile terminal first identifies the started application program to determine whether the application program is a preset application program with a security requirement, that is, whether the started application program has a risk of revealing user privacy data.
In this embodiment, a hierarchical manner may be adopted to determine whether the application is a preset application with a security requirement. Specifically, the mobile terminal divides the currently installed application program of the mobile terminal into different security levels according to configuration data input by a user, for example, a first security level has a higher security requirement on the network environment, a second security level has a lower security requirement on the network environment compared with the first security level, and a third security level has no security requirement on the network environment.
When the mobile terminal identifies whether the started application program is an application program with a safety requirement, if the started application program is identified to be an application program with a first safety level, the started application program is directly determined to be a preset application program; if the started application program is identified to be the application program with the second security level, the started application program is temporarily determined to be a preset application program; and if the started application program is identified to be the application program with the third security level, directly determining that the started application program is not the preset application program.
Optionally, in other embodiments, an application list may be preset locally on the mobile terminal, and the user adds the application with the security requirement to the preset application list, so that the mobile terminal may determine whether the application is the preset application by determining whether the application is located in the preset application list.
After the determination operation on the started application program is completed, if the application program is determined to be a preset application program (including a directly determined preset application program and a temporarily determined preset application program), a safe wireless hotspot in the two currently connected wireless hotspots is further determined.
Optionally, determining whether the wireless hotspot is a secure wireless hotspot may be implemented in a plurality of ways, where determining a secure wireless hotspot of two currently connected wireless hotspots includes:
and judging whether the two wireless hotspots which are connected currently adopt a preset public key encryption algorithm or not, and determining the wireless hotspot which starts the preset public key encryption algorithm as a safe wireless hotspot.
Generally, Wi-Fi technology has several encryption methods as follows:
1. WEP, WEP 64-bit or 128-bit data encryption.
2. WPA-PSK adopts Wi-Fi protected access of a pre-shared key and adopts WPA-PSK standard encryption technology, and the encryption type is TKIP.
3. WPA2-PSK, Wi-Fi protected access with pre-shared keys (version 2), and WPA2-PSK standard encryption technology, with the encryption type being AES.
4. WPA-PSK + WPA2-PSK, allowing the mobile terminal to perform cryptographic encryption using WPA-PSK or WPA 2-PSK.
5. WAPI, namely a wireless local area network authentication and privacy infrastructure, is an encryption technology supported by China.
As is well known, WEP is a simple encryption method based on shared keys, and has low security, and when a wireless hotspot transmits data by using such an encryption method, the transmitted data is easily intercepted. Therefore, in this embodiment, whether the wireless hotspot is safe or not can be determined by identifying whether the wireless hotspot adopts an encryption mode based on a public key encryption algorithm, and specifically, the wireless hotspot adopting a preset public key encryption algorithm is identified as a safe wireless hotspot. The specific selection of the preset public key encryption algorithm is not specifically limited in this embodiment, and a person skilled in the art can select a public key encryption algorithm with a higher encryption level than WEP as the preset public key encryption algorithm according to actual needs.
In addition, a safe hotspot list can be maintained locally at the mobile terminal, a user can add a trusted safe wireless hotspot to the safe hotspot list, and the mobile terminal can determine whether the wireless hotspot is a safe wireless hotspot by judging whether the wireless hotspot is located in the safe hotspot list.
After the identification of the safe wireless hotspot is completed, if the started application program is directly determined to be a preset application program, the mobile terminal directly configures the application program to perform data transmission through the determined safe wireless hotspot. For example, when the started application program is determined to be the application program with the security requirement, if the first wireless hotspot is determined to be the security wireless hotspot, the mobile terminal configures the application program to perform data transmission through the first wireless hotspot; and if the second wireless hotspot is determined to be the safe wireless hotspot, the mobile terminal configures the application program to transmit data through the second wireless hotspot.
On the other hand, if the started application program is temporarily determined to be a preset application program, the mobile terminal further identifies the determined available bandwidth of the secure wireless hotspot, and if the identified available bandwidth of the secure wireless hotspot is greater than or equal to the required bandwidth of the application program, the mobile terminal configures the application program to perform data transmission through the secure wireless hotspot; if the available bandwidth of the secure wireless hotspot is identified to be smaller than the required bandwidth of the application program, the mobile terminal configures the application program to perform data transmission through another wireless hotspot (for example, when the first wireless hotspot is determined as the secure wireless hotspot, the another wireless hotspot is the second wireless hotspot, or when the second wireless hotspot is determined as the secure wireless hotspot, the another wireless hotspot is the first wireless hotspot).
It should be noted that if it is determined that the two currently connected wireless hotspots (i.e., the first wireless hotspot and the second wireless hotspot) are both secure wireless hotspots, the application program may be configured to perform data transmission through the first wireless hotspot or the wireless hotspot;
or, configuring the application program to perform data transmission through the wireless hotspot with better network quality in the two currently connected wireless hotspots, thereby providing better network service for the wireless hotspot.
According to the Wi-Fi control method provided by the embodiment of the invention, for a mobile terminal which is simultaneously connected with two wireless hotspots, when an application program is started, whether the application program is a preset application program with a safety requirement is firstly determined, when the application program is determined to be the preset application program, a safe wireless hotspot in the two currently connected wireless hotspots is further determined, and then the application program is configured to carry out data transmission through the determined safe wireless hotspot, so that a safe network service is provided for the application program, and the purpose of improving the data transmission safety of the application program is achieved.
Further, a second embodiment of the Wi-Fi control method of the present invention is proposed based on the first embodiment of the Wi-Fi control method of the present invention, and in this embodiment, after step S10, the method further includes:
and when the application program is not a preset application program, configuring the application program to transmit data through the wireless hotspot with better network quality in the two currently connected wireless hotspots.
It should be noted that, in this embodiment, on the basis of the foregoing first embodiment, a processing scheme is provided in which the application program is not a preset application program, which is only described below, and other embodiments can refer to the foregoing first embodiment, and are not described herein again.
In this embodiment, when it is recognized that the started application program is not a preset application program, that is, when the application program does not have a security requirement, a wireless hotspot with better network quality in two currently connected wireless hotspots is determined, and then the application program is configured to perform data transmission through the wireless hotspot with better network quality. Specifically, a person skilled in the art can select which parameter to represent the network quality of the wireless hotspot according to actual needs, and may represent the network quality of the wireless hotspot by using the signal strength of the wireless hotspot, may also represent the network quality by using the data transceiving success rate of the wireless hotspot, and may also represent the network quality by using the negotiation rate of the wireless hotspot.
In order to more accurately represent the network quality of the wireless hotspot, the network quality of the wireless hotspot is represented by combining the signal strength, the negotiation rate and the data transceiving success rate in the embodiment. In the following, the network quality of the first wireless hotspot is taken as an example for description, and the detection of the network quality of the second wireless hotspot can be referred to.
Specifically, the mobile terminal first detects a Wi-Fi signal of a first wireless hotspot through the Wi-Fi module 102, then obtains the signal strength and negotiation rate of the first wireless hotspot according to the Wi-Fi signal detection of the first wireless hotspot, and then obtains a data transceiving success rate based on the first wireless hotspot from a bottom layer.
After the signal intensity, the negotiation rate and the data receiving and sending success rate of the first wireless hotspot are obtained, the quality scores corresponding to the signal intensity, the negotiation rate and the data receiving and sending success rate are respectively determined according to the size intervals of the signal intensity, the negotiation rate and the data receiving and sending success rate, then the weighted sum of the quality scores is calculated according to the preset weight coefficients corresponding to the signal intensity, the negotiation rate and the data receiving and sending success rate, and the calculated weighted sum is used as the network quality of the first wireless hotspot.
For example, it is assumed that the preset weight coefficients corresponding to the signal strength, the negotiation rate, and the data transceiving success rate are 0.4, 0.2, and 0.4, respectively.
Dividing 3 intensity intervals corresponding to the signal intensity, and respectively corresponding to quality scores of 60, 40 and 20 from large to small; corresponding to the negotiated rate, 3 rate intervals are also divided, and the rate intervals respectively correspond to quality scores of 60, 40 and 20 from large to small; the data transmission and reception success rate is also divided into 3 rate intervals, and the rate intervals respectively correspond to the quality scores of 60, 40 and 20 from large to small.
If it is determined that the quality scores corresponding to the signal strength, the negotiation rate, and the data transceiving success rate are 60, 40, and 40, respectively, the network quality of the first wireless hotspot is 60 × 0.4+40 × 0.2+40 × 0.4 — 48.

and configuring the application program to perform data transmission through the newly established connected secure wireless hotspot.
It should be noted that, in this embodiment, processing operations of non-secure wireless hotspots in connected wireless hotspots are added on the basis of the foregoing first embodiment, which is only described below, and other embodiments can refer to the foregoing corresponding embodiments, and are not described herein again.
After the mobile terminal finishes judging the two wireless hotspots, if it is determined that the two currently connected wireless hotspots are both unsafe wireless hotspots, the mobile terminal further identifies the network quality of the first wireless hotspot and the second wireless hotspot (the specific identification method may refer to the second embodiment, which is not described herein again), and determines the wireless hotspot with poor network quality in the two wireless hotspots.
After the wireless hotspot with poor network quality is determined, the mobile terminal disconnects the Wi-Fi module 102 from the wireless hotspot with poor network quality, and controls the Wi-Fi module 102 to establish connection with the safe wireless hotspot in the same frequency band where the disconnected wireless hotspot is located. For example, referring to fig. 6, when determining that the network quality of the first wireless hotspot operating in the 2.4G frequency band is poor, the mobile terminal controls the Wi-Fi module 102 to disconnect from the first wireless hotspot, scans other wireless hotspots operating in the 2.4G frequency band, determines a secure wireless hotspot, such as a third wireless hotspot, in the other wireless hotspots, and then controls the Wi-Fi module 102 to establish a connection with the third wireless hotspot.
After the Wi-Fi module 102 establishes a connection with the secure wireless hotspot, the mobile terminal configures the application program to perform data transmission through the secure wireless hotspot for which the connection is newly established.
