104. And selecting at least two wireless networks from the plurality of wireless networks according to the priority order to carry out link aggregation operation.

The higher the priority, the better the network performance, and according to the priority order, at least two wireless networks can be selected from the multiple wireless networks to implement the link aggregation operation.

For example, in an intelligent home environment, the electronic device may determine a distance between the electronic device and another hotspot device to obtain a plurality of distance values, and determine an access priority between the hotspot devices according to the plurality of distance values and network state parameters of the other plurality of hotspot devices, where the access priority reflects a ranking order of network performance to a certain extent, and further preferentially selects 2 hotspot devices with high priorities to perform link aggregation processing, so that a link aggregation network with good network quality is implemented, and data transmission efficiency is facilitated to be improved.

The preset electric quantity threshold value can be set by a user or defaulted by a system. In a specific implementation, the intelligent link aggregation also increases the power consumption of the electronic device to a certain extent, in order to ensure the 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 a preset electric quantity threshold, perform a step of selecting at least two wireless networks from the plurality of wireless networks according to the priority order to perform a link aggregation operation.

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 104, at least two wireless networks may be selected from the plurality of wireless networks according to the 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:

b1, detecting the link quality of the first Wi-Fi data link and detecting the link quality of the second Wi-Fi data link;

b2, 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 B3, 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 B1, 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 one hotspot device and one network state parameter, determines a distance value between the hotspot device corresponding to each wireless network in the plurality of wireless networks and the electronic device to obtain a plurality of distance values, determines a priority order of the plurality of wireless networks according to the plurality of distance values and the network state parameters of the plurality of wireless networks, and selects at least two wireless networks from the plurality of wireless networks to perform link aggregation operation according to the priority order.
