102. Determining a first priority order of the plurality of wireless networks according to the network security levels of the plurality of wireless networks.

The electronic device may determine the first priority order of the plurality of wireless networks according to network security levels of the plurality of wireless networks, for example, the higher the security level is, the higher the priority is.

103. And acquiring the required safety level of the operating environment of the electronic equipment.

The security levels corresponding to different applications are different, even the security levels corresponding to different scenes of different applications are different, for example, the security requirement of a payment scene is high, while the security requirement of a non-payment scene is relatively low, and of course, different locations may also correspond to different security levels, for example, a familiar environment has a higher security level, and an unfamiliar environment has a lower security level. In specific implementation, the requirement security level corresponding to the operating environment can be determined by detecting the operating environment of the electronic device.

Optionally, in the step 103, obtaining the required security level of the operating environment of the electronic device may include the following steps:

32. and determining the required safety level corresponding to the foreground application according to a preset mapping relation between the application and the safety level.

The mapping relationship between the preset application and the security level can be pre-stored in the electronic device, and then, in specific implementation, the electronic device can obtain the current foreground application, and the required security level corresponding to the foreground application can be determined according to the mapping relationship.

33. acquiring a current position;

34. and determining the required safety level corresponding to the current position according to a mapping relation between a preset position and the safety level.

The electronic device may pre-store a mapping relationship between a preset position and a security level, and further, in a specific implementation, the electronic device may obtain a current position, and may determine a required security level corresponding to the current position according to the mapping relationship.

104. And when the required security level is higher than a preset security level, selecting at least two wireless networks from the plurality of wireless networks according to the first priority order to perform link aggregation operation.

The preset security level can be set by the user or defaulted by the system. The higher the priority, the better the security performance, then can select two at least wireless networks from a plurality of wireless networks according to this priority order and be used for realizing link aggregation operation, so, when the security requirement is higher, can select the high network of security to carry out link aggregation, not only promote transmission rate, also guaranteed the security of network environment.

In this embodiment, the network state parameter may be at least one of the following: signal strength value, target data transmission rate, target round trip delay, target bit error rate, etc., without limitation. The network state parameters reflect the stability or communication quality of the wireless network to some extent. In the specific implementation, when the required security level is lower than or equal to the preset security level, the electronic device may acquire the network state parameters of the multiple wireless networks, and further may determine the stability evaluation of each of the multiple wireless networks according to the network state parameters of the multiple wireless networks to obtain multiple evaluation values, and determine the second priority order of the multiple wireless networks according to the multiple evaluation values, for example, the larger the evaluation value is, the higher the priority is, and further, at least two wireless networks may be selected from the multiple wireless networks according to the second priority order to perform link aggregation operation, so that when the security requirement is not high, a wireless network with good stability may be selected to perform link aggregation operation, and the data transmission efficiency is improved.

Therefore, in specific implementation, in an intelligent home environment, the safety of each hotspot device is different, when the safety requirement is high, the hotspot device with high safety can be selected, the safety requirement is low, and the hotspot device with low safety but stable network can be switched to, so that the hotspot device can be flexibly selected to realize link aggregation operation.

Optionally, the network status parameters in the wireless network i include: when the target data transmission rate, the target round trip delay and the target error rate are adopted, the wireless network i is any one of the wireless networks; the step a2 of performing the stability evaluation on each of the wireless networks according to the network status parameters of the wireless networks to obtain a plurality of evaluation values may include the following steps:

a21, determining a target first evaluation value corresponding to the target data transmission rate according to a first mapping relation between a preset data transmission rate and the first evaluation value;

a22, determining a target second evaluation value corresponding to the target round-trip delay according to a second mapping relation between a preset round-trip delay and the second evaluation value;

a23, determining a target third evaluation value corresponding to the target error rate according to a third mapping relation between a preset error rate and the third evaluation value;

a24, acquiring a first weight corresponding to the first evaluation value, a second weight corresponding to the second evaluation value and a third weight corresponding to the third evaluation value, wherein the sum of the first weight, the second weight and the third weight is 1;

and A25, performing weighted operation according to the target first evaluation value, the target second evaluation value, the target third evaluation value, the first weight, the second weight and the third weight to obtain an evaluation value of the wireless network i.

The electronic device may store a first mapping relationship between a preset data transmission rate and a first evaluation value, a second mapping relationship between a preset round-trip delay and a second evaluation value, and a third mapping relationship between a preset error rate and a third evaluation value in advance. Assume that the network state parameters of wireless network i include: when the target data transmission rate, the target round trip delay and the target error rate are determined, the wireless network i is any one of at least two wireless networks, further, a target first evaluation value corresponding to the target data transmission rate can be determined according to the first mapping relation, a target second evaluation value corresponding to the target round trip delay can be determined according to the second mapping relation, and a target third evaluation value corresponding to the target error rate can be determined according to the third mapping relation, of course, a first weight corresponding to the first evaluation value, a second weight corresponding to the second evaluation value and a third weight corresponding to the third evaluation value can be stored in the electronic device in advance, the sum of the first weight, the second weight and the third weight is 1, further, weighting operation can be performed according to the target first evaluation value, the target second evaluation value, the target third evaluation value, the first weight, the second weight and the third weight, the evaluation value of the wireless network i is obtained, and specifically, the evaluation value of the wireless network i can be obtained according to the following formula: the evaluation value of the wireless network i is the first target evaluation value + the first weight + the second target evaluation value + the second weight + the third target evaluation value + the third weight.

Optionally, before the step 101, the following steps may be further included:

b1, detecting the current electric quantity of the electronic equipment;

b2, when the current electric quantity is larger than a preset electric quantity threshold value, executing the step of network searching.

The preset electric quantity threshold value can be set by a user or defaulted by a system. In specific implementation, the intelligent link aggregation also increases the power consumption of the electronic device to a certain extent, in order to ensure smooth implementation of the intelligent aggregation link function, the electronic device may detect the current electric quantity of the electronic device, and when the current electric quantity is greater than the preset electric quantity threshold, step 101 is executed.

In the embodiment of the present application, link aggregation is that a device may use two or more network ports to surf the internet at the same time, for example, a Wi-Fi and a data network (data network, which may also be referred to as a mobile data network) may be used to access the network at the same time by link aggregation on a mobile phone, or 2 or more Wi-Fi networks may be used to access the network at the same time. The intelligent Link Aggregation (SLA) function refers to intelligently distributing internet access requests of users to different internet access interfaces (cellular communication module interfaces and Wi-Fi communication module interfaces). Link aggregation requires at least two or more available networks, so the SLA presupposes coexistence of Wi-Fi and data networks.

Optionally, when the electronic device starts the intelligent link aggregation function, the electronic device may perform step 101.

Optionally, in the step a4, at least two wireless networks may be selected from the plurality of wireless networks according to the second priority order, and a link aggregation operation is performed based on the at least two wireless networks, where the at least two wireless networks include 2 Wi-Fi data networks, the method may include the following steps:

c1, detecting the link quality of the first Wi-Fi data link and detecting the link quality of the second Wi-Fi data link;

c2, determining the proportion of data packets between the Wi-Fi data link and the second Wi-Fi data link according to the link quality of the first Wi-Fi data link and the link quality of the second Wi-Fi data link;

and C3, distributing the data packets to be transmitted in the first Wi-Fi data link and the second Wi-Fi data link according to the data packet distribution proportion.

The link quality of the Wi-Fi data link can be determined by the uplink and downlink data transmission rate, the round-trip delay, the bit error rate and the like of the Wi-Fi data link. The higher the transmission rate of the uplink and downlink data, the smaller the round-trip delay, the lower the error rate and the higher the link quality of the Wi-Fi data link; the lower the transmission rate of the uplink data and the downlink data, the larger the round-trip delay, the higher the error rate and the lower the link quality of the Wi-Fi data link.

The Wi-Fi data link can include a Wi-Fi uplink and a Wi-Fi downlink. The quality of the Wi-Fi uplink may be determined by the uplink data transmission rate, round trip delay, bit error rate, etc. of the Wi-Fi uplink. The quality of the Wi-Fi downlink data link can be determined by the downlink data transmission rate, the round-trip delay, the bit error rate and the like of the Wi-Fi data link.

The error rate is an index for measuring the accuracy of data transmission in a specified time, and is equal to 100% of error in transmission/total number of transmitted codes.

Wherein the electronic device may initiate the intelligent link aggregation function before performing step 101. The electronic device may also open dual Wi-Fi connections simultaneously.

When the electronic device starts the intelligent link aggregation function, the electronic device may send a network request (network request) to the network terminal to enable the data network, so that the electronic device may use 2 Wi-Fi networks simultaneously when the first Wi-Fi network and the second Wi-Fi network are started simultaneously.

Optionally, the electronic device detects the link quality of the first Wi-Fi data link, and specifically includes the following steps:

the electronic equipment measures the data transmission rate, the round trip delay and the error rate of the first Wi-Fi data link, and determines the link quality of the first Wi-Fi data link based on the round trip delay, the data transmission rate and the error rate of the Wi-Fi data link;

the electronic device detecting the link quality of the second Wi-Fi data link may specifically include the following steps:

the electronic device measures the data transmission rate, the round trip delay and the error rate of the second Wi-Fi data link, and determines the link quality of the second Wi-Fi data link based on the round trip delay, the data transmission rate and the error rate of the second Wi-Fi data link.

In the embodiment of the application, if the link quality of a first Wi-Fi data link is better than that of a second Wi-Fi data link, determining that the data packet distribution ratio between the first Wi-Fi data link and the second Wi-Fi data link is more than 1; and if the link quality of the second Wi-Fi data link is better than that of the first Wi-Fi data link, determining that the data packet distribution ratio between the second Wi-Fi data link and the first data link is more than 1.

The link quality of the Wi-Fi data link can be scored based on the uplink and downlink data transmission rate, the round-trip delay and the bit error rate of the Wi-Fi data link, so that the quality score of the Wi-Fi data link is obtained. The electronic device may use a ratio of a quality of the first Wi-Fi data link to a quality of the second Wi-Fi data link as a packet allocation ratio between the first Wi-Fi data link and the second Wi-Fi data link.

The electronic equipment can also determine the quality grade of the first Wi-Fi data link according to the quality score of the first Wi-Fi data link, determine the quality grade of the second Wi-Fi data link according to the quality score of the second Wi-Fi data link, and determine the data packet distribution proportion between the first Wi-Fi data link and the second Wi-Fi data link according to the quality grade of the first Wi-Fi data link and the quality grade of the second Wi-Fi data link. Of course, the packet allocation ratio between the first Wi-Fi data link and the second Wi-Fi data link may also be determined according to the ratio of the quality level of the first Wi-Fi data link to the quality level of the second Wi-Fi data link. For example, if the link quality of the first Wi-Fi data link is class I and the quality class of the second Wi-Fi data link is class I, the packet allocation ratio between the first Wi-Fi data link and the second Wi-Fi data link is 1: 1; if the link quality of the first Wi-Fi data link is I level and the quality level of the second Wi-Fi data link is 2 level, the data packet distribution ratio between the first Wi-Fi data link and the second Wi-Fi data link is 1: 2; if the link quality of the first Wi-Fi data link is I level and the quality level of the second Wi-Fi data link is 3 level, the data packet distribution ratio between the first Wi-Fi data link and the second Wi-Fi data link is 1: 3; if the link quality of the first Wi-Fi data link is I level and the quality level of the second Wi-Fi data link is 4 level, the data packet distribution ratio between the first Wi-Fi data link and the second Wi-Fi data link is 1: 4; and if the link quality of the first Wi-Fi data link is I grade and the quality grade of the second Wi-Fi data link is 5 grade, the data packet distribution ratio between the first Wi-Fi data link and the second Wi-Fi data link is 1: 5.

In this embodiment, the electronic device may send an uplink data packet and may also receive a downlink data packet. The data packet to be transmitted may be an uplink data packet or a downlink data packet. For uplink data packets, the electronic device may allocate the uplink data packets for transmission in a first Wi-Fi uplink and a second Wi-Fi uplink; for downlink data packets, the electronic device may allocate the downlink data packets for transmission in the first Wi-Fi downlink data link and the second Wi-Fi downlink data link.

The data packets to be transmitted may be initiated by different services in the electronic device, for example, the data packets to be transmitted may be initiated by any one of a video service, a game service, a voice service, and an instant messaging service.

Optionally, in step C1, the electronic device detects the link quality of the first WiFi data link and detects the link quality of the second Wi-Fi data link, which may specifically include the following steps:

the electronic device measures a maximum data transmission rate of the first WiFi data link, measures a maximum data transmission rate of the second Wi-Fi data link, and determines link quality of the first WiFi data link and link quality of the second Wi-Fi data link based on the maximum data transmission rate of the first WiFi data link and the maximum data transmission rate of the second Wi-Fi data link.

In the embodiment of the present application, the link quality of the first Wi-Fi data link and the link quality of the second Wi-Fi data link may be calculated according to the following formulas:

weigh_wifi1＝max_speed_wifi1/(max_speed_wifi 1+max_speed_wifi2)；

weigh_wifi2＝1-weigh_wifi1；

wherein, weight _ WiFi1 represents the link quality of the first WiFi data link, weight _ WiFi2 represents the link quality of the second WiFi data link, max _ speed _ WiFi1 represents the maximum data transmission rate of the first WiFi data link, and max _ speed _ WiFi2 represents the maximum data transmission rate of the second WiFi data link. The sum of the link quality of the first WiFi data link and the link quality of the second Wi-Fi data link is equal to 1.

The electronic device may determine a packet allocation ratio between the first WiFi data link and the second Wi-Fi data link based on a ratio of a link quality of the first WiFi data link to a link quality of the second Wi-Fi data link.

For example, if the link quality of the first WiFi data link is 0.2 and the link quality of the second Wi-Fi data link is 0.8, it is determined that the packet allocation ratio between the first WiFi data link and the second Wi-Fi data link is 2: 8.

Optionally, the maximum data transfer rate of the second Wi-Fi data link and the maximum data transfer rate of the first WiFi data link may be modified by incrementally calculating the data rates of WiFi1 and WiFi2 receive (rx) interfaces.

For example, data incremental computation rates on WiFi1 and WiFi2 receiving (rx) interfaces are counted every 1s, and the maximum data transmission rate of the first WiFi data link and the maximum data transmission rate of the second Wi-Fi data link are corrected through the data incremental computation rates.

tmp_speed＝(rx_bytes-last_rx_bytes)/1；

The modified max _ speed _ wifi1 is max (max _ speed _ wifi1, tmp _ speed);

the modified max _ speed _ wifi2 is max (max _ speed _ wifi2, tmp _ speed);

wherein rx _ bytes represents the data receiving amount on the WiFi1 and WiFi2 receiving interfaces in one second, last _ rx _ bytes represents the data receiving amount on the WiFi1 and WiFi2 receiving interfaces in the last second, tmp _ speed represents the data incremental calculation rate, max _ speed _ WiFi1 represents the maximum data transmission rate of the first WiFi data link, and max _ speed _ WiFi2 represents the maximum data transmission rate of the second Wi-Fi data link. The modified max _ speed _ wifi1 is the maximum value of max _ speed _ wifi1 and tmp _ speed, and the modified max _ speed _ wifi2 is the maximum value of max _ speed _ wifi2 and tmp _ speed.

Optionally, the maximum data transmission rate of the second Wi-Fi data link and the maximum data transmission rate of the first WiFi data link may be modified by a statistical Round-Trip Time (rtt).

For example, the electronic device may calculate the delay on the two interfaces (Wi-Fi communication module interface 1 and Wi-Fi communication module interface 2) based on the rtt of the tcp itself, and one data link may calculate only the rtt of the first request after the three-way handshake, such as http get and rrt of http post. The 3-way handshake refers to 3 acknowledgement procedures for TCP to establish a connection. The Transmission Control Protocol (tcp) counts rtt through a tcp _ rtt _ estimator () function to calculate a Retransmission Timeout (RTO), so that the delay calculation is calculated in the tcp _ rtt _ estimator () function.

The electronic device respectively determines a current first RTT of a first WiFi data link and a current first RTT of a second Wi-Fi data link, and the method comprises the following steps:

the electronic equipment determines a second RTT for operating a Transmission Control Protocol (TCP);

the electronic equipment respectively acquires a third RTT determined last time by the first Wi-Fi communication module and the second Wi-Fi communication module;

and the electronic equipment determines the current first RTT of the first WiFi communication module and the second Wi-Fi communication module according to the determined second RTT and the obtained last determined third RTT of the first Wi-Fi communication module and the second Wi-Fi communication module.

Specifically, the following formulas may be adopted to calculate the current first RTT of the first WiFi data link and the current first RTT of the second Wi-Fi data link:

rtt_wifi_1＝(rtt_wifi1_3+rtt_2)/2

rtt_wifi2_1＝(rtt_wifi2_3+rtt_2)/2

wherein, RTT _ WiFi _1 represents a current first RTT of the first WiFi data link, RTT _2 represents a second RTT running a transmission control protocol TCP, and RTT _ WiFi1_3 represents a last determined third RTT of the first WiFi data link; RTT _ wifi2_1 represents the current first RTT of the second Wi-Fi data link, RTT _2 represents the second RTT running one transmission control protocol TCP, and RTT _ wifi2_3 represents the last determined third RTT of the second Wi-Fi data link.

According to the embodiment of the application, the data transmission rate and the round trip delay are considered, and the calculation accuracy of the link quality of 2 WiFi data links can be improved.

It can be seen that the link aggregation implementation method described in the embodiment of the present application is applied to an electronic device, performs network search to obtain a plurality of wireless networks, where each wireless network corresponds to a hotspot device and a network security level, determines a first priority order of the plurality of wireless networks according to the network security levels of the plurality of wireless networks, obtains a required security level of an operating environment of the electronic device, and selects at least two wireless networks from the plurality of wireless networks according to the first priority order to perform link aggregation operation when the required security level is higher than a preset security level, so that a network with high security can be selected to implement link aggregation when the security level is higher, that is, network environment security is ensured, and network transmission efficiency is also improved.
