The following describes embodiments of the present application in detail.

As shown in fig. 2A, a method for network handover provided in an embodiment of the present application is applied to the electronic device, where the electronic device has currently accessed a first LIFI network, and specifically includes the following steps:

step 201: determining a first application running in the foreground of the electronic equipment.

before accessing the first LIFI network, the electronic equipment starts the LIFI function. The specific implementation mode of the electronic device for starting the LIFI function is as follows: the method comprises the steps that an electronic device displays a setting interface, wherein the setting interface comprises an LIFI setting item, the LIFI setting item comprises an LIFI setting switch, and the LIFI setting switch is in a closed state at present; and under the condition that the clicking operation aiming at the LIFI setting switch is detected, the electronic equipment places the LIFI setting switch in an opening state and starts the LIFI function, and an interface is displayed as shown in fig. 2B.

the first LIFI network is the LIFI network with the maximum data transmission rate in the LIFI networks which can be accessed by the electronic equipment. For example, the LIFI network accessible to the electronic device includes an LIFI network 1, an LIFI network 2, and an LIFI network 3, where a data transmission rate of the LIFI network 1 is less than a data transmission rate of the LIFI network 2 is less than a data transmission rate of the LIFI network 3, and then the first LIFI network is the LIFI network 3.

or the first LIFI network is the LIFI network which is closest to the first distance between the access point and the electronic equipment in the LIFI network which can be accessed by the electronic equipment. For example, an LIFI network accessible to the electronic device includes an LIFI network 1, an LIFI network 2, and an LIFI network 3, a distance between an access point of the LIFI network 1 and the electronic device is 3 meters, a distance between the access point of the LIFI network 1 and the electronic device is 4 meters, a distance between the access point of the LIFI network 1 and the electronic device is 5 meters, and if the distance between the access point of the LIFI network 1 and the electronic device is < the distance between the access point of the LIFI network 2 and the electronic device < the distance between the access point of the LIFI network 3 and the electronic device, the LIFI network 1 is the first LIFI network.

or the first LIFI network is a LIFI network randomly selected from LIFI networks accessible to the electronic device.

Or the first LIFI network is a LIFI network which is accessed by the electronic equipment by default. For example, the LIFI network accessible to the electronic device includes an LIFI network 1, an LIFI network 2, and an LIFI network 3, where the LIFI network 2 is the LIFI network that the electronic device is defaulted to access, and then the LIFI network 2 is the first LIFI network.

Wherein the determining a first distance between the electronic device and an access point of the first LIFI network comprises: sending a distance detection request to an access point of the first LIFI network, wherein the distance detection request is used for requesting immediate feedback response when the distance detection request is received; receiving a distance detection response sent by an access point of the first LIFI network for the distance detection request; and determining a first distance between the electronic equipment and an access point of the first LIFI network according to the sending time of the distance detection request and the receiving time of the distance detection response.

After determining that network handover is required, the method further includes: the connection with the first LIFI network is disconnected.

In an implementation manner of the present application, after step 204, the method further includes: and limiting access to the first LIFI network, wherein the limiting time duration is a first time duration.

Wherein the first duration is fixed (e.g., 8min, 25min, 40min, 1h or other values). Or the first duration is determined by the electronic device based on the current first application, and specifically includes: the electronic device determines the duration corresponding to the current first application based on a first mapping relationship between the first application and the duration, where the first mapping relationship between the first application and the first duration is shown in table 1.

First application	Duration of time
		Video chat	10min
Game machine	5min
		Reading	4min
……	……

In an implementation manner of the present application, after the limiting access to the first LIFI network, the method further includes: and marking the first LIFI network in an LIFI setting interface. The LIFI setting interface after marking the first LIFI network is shown in fig. 2C, the first LIFI network is "2345", and the first LIFI network is marked by thickening the name of the first LIFI network. The labeling shown in fig. 2C is for example only and does not limit the embodiments of the present application.

The first LIFI network may be marked by changing a color of a name of the first LIFI network, or by adding a mark beside the name of the first LIFI network.

in an implementation manner of the present application, the determining a data transmission rate of the first LIFI network includes:

Determining a first numerical value and/or a second numerical value, wherein the first numerical value is the total data volume sent by the electronic equipment by using the first LIFI network in a first time period, the second numerical value is the total data volume received by the electronic equipment by using the first LIFI network in the first time period, and the termination time of the first time period is the current time; and determining the data transmission rate of the first LIFI network according to the first numerical value and/or the second numerical value.

The duration of the first time interval may be, for example, 2min, 4min, 5min, 9min, 15min, or other values.

Optionally, the determining a data transmission rate of the first LIFI network according to the first value and/or the second value includes: determining the data transmission rate based on a first formula, the first numerical value, and the second numerical value if the current task of the first application is a first task.

The first task is, for example, voice chat, video chat, game, or other tasks that send and receive large amounts of data.

Wherein the first formula is: the speed is a data transmission rate, T is a duration of a first time period, a is a total data volume sent by the electronic device using the first LIFI network, and B is a total data volume received by the electronic device using the first LIFI network.

for example, assuming that the duration of the first period is 2min, the first value determined by the electronic device is 6MB, and the second value is 5MB, the data transmission rate of the first LIFI network is [ (6+5) ]/2 is 5.5 MB/min.

Optionally, the determining the data transmission rate according to the first value and/or the second value includes: determining the data transmission rate based on a second formula and the second value in a case where the current task of the first application is a second task.

And under the second task, the total data amount expected to be received by the electronic equipment is larger than a second value, and the total data amount expected to be sent by the electronic equipment is smaller than the second value. The second task is, for example, audio playing, video downloading, video watching, or other tasks that receive a large amount of data.

Wherein the second formula is: the speed is (E + F)/T, where the speed is a data transmission rate, the T is a duration of a first time period, the E is a total data volume received by the electronic device using the first LIFI network, and the F is a fixed value.

for example, assuming that the duration of the first period is 2min, the second value is 9MB, and F is 0.1MB, the data transmission rate of the first LIFI network is (9+0.1)/2 is 4.55 MB/min.

optionally, the determining the data transmission rate according to the first value and/or the second value includes: determining the data transmission rate based on a third formula and the first value in a case where the current task of the first application is a third task.

And under the third task, the total data amount expected to be sent by the electronic equipment is larger than a third value, and the total data amount expected to be received by the electronic equipment is smaller than the third value. The third task is, for example, application upload, video upload, audio upload, or other task that transmits a large amount of data.

wherein the third formula is: the speed is a data transmission rate, T is a duration of a first time period, G is a total data volume sent by the electronic device using the first LIFI network, and H is a fixed value.

for example, assuming that the duration of the first period is 2min, the first value is 9MB, and H is 0.2MB, then the data transmission rate of the first LIFI network is (9+0.2)/2 is 4.6 MB/min.

It can be seen that, in the embodiment of the present application, the data transmission rate of the first LIFI network is calculated by using the total data amount sent and/or received by the electronic device through the first LIFI network, so that the accuracy of determining the data transmission rate can be improved.

The first value, the second value, and the third value may be the same or different, and are not limited herein.

the first threshold, the second threshold, the third threshold, and the fourth threshold are associated with the first application, that is, the 4 thresholds corresponding to different applications may be the same or different. For example, the first threshold of the application 1 association is a1, the second threshold is a2, the third threshold is a3, and the fourth threshold is a4, and the first threshold of the application 2 association is a1, the second threshold is a5, the third threshold is a6, and the fourth threshold is a 4. The first threshold of the application 3 association is a7, the second threshold is a8, the third threshold is a9, and the fourth threshold is a 10.

The third mapping relationship is shown in table 3.

TABLE 3

Status of signal strength indicator	Signal strength
		one lattice signal	1

		Three-lattice signal	3

The signal strength indicator has, for example, a one-cell signal, a two-cell signal, and a three-cell signal. As shown in fig. 2D, in the currently accessible WIFI network of the electronic device, for example, the WIFI network 1234 and the WIFI network 2345, the state of the signal strength identifier of the WIFI network 1234 is a two-lattice signal, the state of the signal strength identifier of the WIFI network 2345 is a three-lattice signal, and the electronic device may determine, based on table 3, that the signal strength of the WIFI network 1234 is 2, and the signal strength of the WIFI network 2345 is 3.

Optionally, the determining a third distance between the electronic device and the access point corresponding to each WIFI network includes:

The electronic equipment sends a distance detection request to an access point corresponding to each WIFI network, wherein the distance detection request is used for requesting immediate feedback response when the distance detection request is received; receiving a distance detection response sent by an access point corresponding to each WIFI network aiming at the distance detection request; and determining a third distance between the electronic equipment and the access point corresponding to each WIFI network according to the sending time of the distance detection request and the receiving time of the distance detection response.

respectively determining an evaluation value of each WIFI network in the WIFI networks based on a tenth formula, the access priorities, the signal strengths and the third distances, wherein the evaluation value is used for evaluating the importance degree of each WIFI network;

And determining a first WIFI network based on the plurality of determined evaluation values.

Wherein the tenth formula is: t is an evaluation value, o, p and q are weights, the sum of o, p and q is equal to 1, U is an access priority, V is a signal strength, and W is a distance. O may be greater than p, less than p, or equal to p; a may be greater than q, may be less than q, or may be equal to q; p may be greater than q, less than q, or equal to q, and is not limited herein.
