Also, although a logical order is shown in the flowchart diagrams, in some cases the steps shown or described may be performed in a different order than herein.

Figure 1 is a schematic flowchart of a method for implementing handover between networks in an embodiment of the present application. As shown in Figure 1, it may include:

Step 100: The electronic device determines that the quality of the first network has deteriorated based on the network quality of the first network currently accessed.

In an exemplary example, the first network is a Wi-Fi network, and step 100 may include:

It is determined that the round-trip time (RTT, Round-Trip Time) is greater than the preset RTT duration threshold, and the Wi-Fi transmission power (Tx Power) is less than the preset first transmission power threshold, and it is determined that the first network quality has deteriorated.

Among them, RTT represents the total delay experienced from the time the sender sends data to the time the sender receives the confirmation from the receiver. The larger the RTT, the longer the round trip time, which means the longer the network delay. The smaller the Wi-Fi Tx Power, the smaller the transmit power level of the electronic device connected to the control channel of the cell, which means the worse the network signal.

It is determined that the RTT is greater than the preset RTT duration threshold and the throughput (Throughput) is less than the preset throughput threshold, and it is determined that the first network quality has deteriorated.

Among them, throughput represents the amount of data that the router can process per second. The smaller the Wi-Fi Throughput, the lower the network rate will be.

It is determined that the RTT is greater than the preset RTT duration threshold, the Wi-Fi Tx Power is less than the preset first transmission power threshold, and the throughput is less than the preset throughput threshold, and it is determined that the first network quality has deteriorated.

In an exemplary example, the first network is a cellular network (Cellular Network), also called a mobile network (Mobile Network). Step 100 may include:

It is determined that the received signal strength indicator (RSSI, Received Signal Strength Indicator) is less than the preset RSSI threshold, and the cellular transmission power (Tx Power) is less than the preset second transmission power threshold, and it is determined that the first network quality has deteriorated.

Among them, RSSI reflects the received signal strength and interference level of the current channel. The smaller the RSSI, the weaker the received signal.

In an exemplary example, the first network is a cellular network, and step 100 may include:

It is determined that the RSSI is less than the preset RSSI threshold, and the Clear Channel Assessment (CCA, Clear Channel Assessment) level (Level) is less than the preset assessment threshold, and it is determined that the first network quality has deteriorated.

Among them, the smaller the CCA Level, the fewer available channels, which means the network is about to be congested.

It is determined that the RSSI is less than the preset RSSI threshold, the cellular Tx Power is less than the preset second transmission power threshold, and the CCA Level is less than the preset evaluation threshold, and it is determined that the first network quality has deteriorated.

It should be noted that the parameters reflecting network quality listed in the embodiments of this application, such as Tx Power, Throughput, RTT, HTTP and other parameters, are only some implementation examples and are not used to limit the scope of protection of this application. The parameters that affect network quality are not limited to the above parameters. In actual evaluation, other parameters can be selected to evaluate network quality.

Step 101: Perform network speed detection on the first network. If the time difference between two consecutive network speed detections is greater than the preset time length threshold, the electronic device switches from the first network to the second network.

In an exemplary example, network speed detection may include but is not limited to detection methods such as Hypertext Transfer Protocol (HTTP, Hypertext Transfer Protocol) network signal quality detection, Ping, Domain Name System (DNS, Domain Name System) information detection, and other detection methods.

Through the method for implementing handover between networks provided by the embodiments of the present application, when the network signal quality of the first network currently accessed by the electronic device deteriorates, the electronic device will access the second network in advance, so that when the signal quality of the first network deteriorates, the electronic device will access the second network in advance. It switched to the second network in time, which improved the user experience. Taking the cellular network and Wi-Fi network switching mechanism as an example, as long as there is a Wi-Fi signal, the Wi-Fi network can be connected first; and when the Wi-Fi signal becomes poor, the cellular network can be switched. In this way, when Wi-Fi is encountered When the Fi signal is poor, it will not be affected due to timely switching to the cellular network. impact user experience.

Step 200: Determine whether the Wi-Fi transmission power is less than the first transmission power threshold. If the Wi-Fi transmission power is less than the first transmission power threshold, proceed to step 201; if the Wi-Fi transmission power is not less than the first transmission power threshold, proceed to step 200. 203.

Step 201: Determine whether the throughput is less than the throughput threshold. If the throughput is less than the throughput threshold, go to step 202; if the throughput is not less than the throughput threshold, go to step 203.

Step 202: Determine whether the RTT is greater than the first duration threshold. If the RTT is greater than the first duration threshold, proceed to step 204; if the RTT is not greater than the first duration threshold, proceed to step 203.

Step 203: After the preset first time interval Δt11, return to step 200 and continue to detect WIFI signals.

Step 204: HTTP network detects network signal quality.

Step 205: Check whether the time difference between two consecutive HTTP network detections is greater than the preset duration threshold. If the time difference is greater than the preset duration threshold, proceed to step 206; if the time difference is not greater than the preset duration threshold, return to step 203.

Step 206: The electronic device switches from the Wi-Fi network to the cellular network.

Through the first embodiment of switching from the Wi-Fi network to the cellular network shown in Figure 2, when the network signal quality of the Wi-Fi network currently connected to the electronic device deteriorates, the electronic device will access the cellular network in advance, so that When the Wi-Fi network signal is poor, it switches to the cellular network in time, improving the user experience. For example: when going out to take a taxi, if the Wi-Fi signal connected to the mobile phone becomes poor, it will switch to the cellular network in time to ensure that the taxi information can be refreshed; another example: when playing games at home, when the game freezes, It will no longer continue to connect to the Wi-Fi network, but will switch to the cellular network to play games, ensuring user experience.

Figure 3 is a schematic flowchart of the first embodiment of switching from a cellular network to a Wi-Fi network in this embodiment of the present application. As shown in Figure 3, it may include:

Step 300: Determine whether the cellular transmission power is less than the second transmission power threshold. If the cellular transmission power is less than the second transmission power threshold, proceed to step 301; if the cellular transmission power is not less than the second transmission power threshold, proceed to step 303.

Step 301: Determine whether the RSSI is less than the preset RSSI threshold. If the RSSI is less than the preset RSSI threshold, go to step 302; if the RSSI is not less than the preset RSSI threshold, go to step 303.

Step 302: Determine whether the CCA Level is less than the preset evaluation threshold. If the CCA Level is less than the preset evaluation threshold, proceed to step 304; if the CCA Level is not less than the preset evaluation threshold, proceed to Step 303.

Step 303: After the preset first time interval Δt11, return to step 300 and continue to detect cellular signals.

Step 304: HTTP network detects network signal quality.

Step 305: Check whether the time difference between two consecutive HTTP network detections is greater than the preset duration threshold. If the time difference is greater than the preset duration threshold, proceed to step 306; if the time difference is not greater than the preset duration threshold, return to step 303.

Step 306: The electronic device switches from the cellular network to the Wi-Fi network.

Through the first embodiment of switching from a cellular network to a Wi-Fi network as shown in Figure 3, when the network signal quality of the cellular network currently accessed by the electronic device deteriorates, the electronic device will access the Wi-Fi network in advance, so that When the cellular network signal is poor, it switches to the Wi-Fi network in time, improving the user experience. For example: after entering the home, due to poor cellular network signal in certain locations in the home, such as the bathroom, etc., and the cellular signal connected to the mobile phone becomes poor, it will switch to the Wi-Fi network in time to ensure the user's network experience. .

It can be seen from the embodiments shown in Figures 2 and 3 that the method for switching between a Wi-Fi network and a cellular network provided by embodiments of the present application evaluates and evaluates the network status of the network currently accessed by the electronic device before switching the network. Judgment to determine whether network switching is ultimately required.

Taking the first embodiment of switching from a Wi-Fi network to a cellular network shown in Figure 2 as an example, the signal quality of the currently accessed Wi-Fi network is first evaluated, and then it is determined whether to trigger the switching to the cellular network. In this process, the Wi-Fi network signal quality was evaluated, but the cellular network signal was not evaluated. In this way, there is a possibility that the cellular network signal is worse than the Wi-Fi network. At this time, if the signal quality is poor Switching from a Wi-Fi network to a cellular network will still cause electronic devices to be in an environment with poor network signals. Similarly, similar problems also exist for the first embodiment of switching the Wi-Fi network from the cellular network shown in FIG. 3 .

As shown in Figure 4, before the electronic device switches from the first network to the second network, the method for implementing handover between networks provided by the embodiment of the present application may also include:

For the Http continuous detection time difference in the parameters:

When the HTTP continuous detection time difference is <△t*50%, the corresponding level of the HTTP continuous detection time difference is excellent. The scoring of the HTTP continuous detection time difference is shown in Table 2. After scoring, the S_http first score value/second score value is obtained is 100;

When △t*50%<Http continuous detection time difference<△t*70%, the corresponding level of Http continuous detection time difference is good. The scoring of Http continuous detection time difference is shown in Table 2. The first score of S_http obtained after scoring Value/second scoring value is 80;

When △t*70% <Http continuous detection time difference <△t*85%, the corresponding level of Http continuous detection time difference is medium. The scoring of Http continuous detection time difference is shown in Table 2. The first score of S_http obtained after scoring Value/second scoring value is 60;

Among them, 0＜Pa1＜1, 0＜Pb1＜1, 0＜Pc1＜1, 0＜Pd1 <1, and Pa1+Pb1+Pc1+Pd1=1. Pa2, Pb2, Pc2 and Pd2 are the weight values of tx pwr2, throughput2, RTT2 and Http2 continuous detection time difference indicators respectively, among which, 0＜Pa2＜1, 0＜Pb2＜1, 0＜Pc2＜1, 0＜Pd2＜1 , and Pa2+Pb2+Pc2+Pd2=1.

Step 401: The evaluation result of the second network is better than the evaluation result of the first network, and switching from the first network to the second network is performed.

In an exemplary example, step 401 may include: comparing the first score value and the second score value, determining that the second score value of the second network is greater than the first score value of the first network, and performing switching from the first network to the second network.

In an exemplary example, it is determined that the second score value of the second network is not greater than the first score value of the first network, and after the preset second time interval Δt22, the results of the first network and the second network are returned. The signal quality is evaluated separately until it is determined that the second score value of the second network is higher than the first score value of the first network, and switching from the first network to the second network is performed. In one embodiment, when the number of times of detecting the signal quality of the first network and the second network exceeds a preset threshold, you can also choose to exit the detection and not perform network switching.

Through the embodiment shown in Figure 4, the network signal quality of the first network is evaluated, and the network signal of the second network is also evaluated, which avoids that the network signal of the second network is worse than that of the first network. The possibility better ensures that the signal quality of the second network to be switched to is indeed better than that of the first network, and achieving timely switching also ensures the stability of the switching and improves the user experience.

In an exemplary example, after determining that the second score value of the second network is greater than the first score value of the first network and before performing the switch from the first network to the second network, the method may further include:

Calculate the difference between the second score value of the second network and the preset handover confirmation value;

If the calculated difference is greater than the first score of the first network, the step of switching from the first network to the second network is performed.

In one embodiment, the handover confirmation value is a preset parameter value used to ensure that the signal quality of the second network to which the handover is switched is indeed stably better than the signal quality of the first network.

By adding further confirmation of the switching confirmation value, the problem of endless switching between the first network and the second network is avoided when the score values of the first network and the second network are different, and the electronic device will not be left in a network unstable state. The environment effectively avoids the "ping-pong effect" of back-and-forth switching and ensures the user's network experience.

Taking the cellular network and Wi-Fi network switching mechanism as an example, as long as there is a Wi-Fi signal, the Wi-Fi network can be connected first; and when the Wi-Fi signal becomes poor, the cellular network can be switched. In this way, when Wi-Fi is encountered Even when the Fi signal is very poor, the user experience will not be affected because it switches to the cellular network in time.

This better ensures that the signal quality of the second network to which the switch is made is indeed better than that of the first network, and achieving timely switching also ensures the stability of the switching and improves the user experience.

In an illustrative example, the processing module is also used to:
