In the embodiment of the application, when the first virtual client performs data communication with the first access point, the electronic device establishes a data link with the target access point through the second virtual client in advance.
Illustratively, when only a single target access point exists in the network, a data link with the single target access point is established in advance through the second virtual client.
When there are multiple target access points in the network, for example: target access point 1, target access point 2 and target access point 3, in which case the electronic device configures a plurality of virtual clients, for example: the electronic equipment comprises a virtual client 1, a virtual client 2 and a virtual client 3, wherein the electronic equipment can establish a data link with a target access point 1 through the virtual client 1 in advance, establish a data link with the target access point 2 through the virtual client 2 and establish a data link with the target access point 3 through the virtual client 3. Of course, the virtual client 1 may also establish a data link with any one of the target access points 2 or 3, and the embodiment of the present application does not limit that a specific virtual client establishes a data link with a specific target access point.
In an embodiment of the present application, please refer to fig. 4 for a method for an electronic device to establish a data link between a second virtual client and a target access point, where fig. 4 is a schematic flowchart of a method for establishing a data link between a second virtual client and a target access point according to an embodiment of the present application.

S402, the electronic device transmits the encapsulation message through a data link between the first virtual client and the first access point and a data transmission network between the first access point and the target access point, and establishes a data link between the second virtual client and the target access point.
Specifically, in the embodiment of the present application, a data transmission network between the first access point and the target access point, that is, a backbone network for transmitting data between the access point and the target access point, where the backbone network is a large transmission network, and is used to connect to a small transmission network and transmit data.
In the embodiment of the application, the electronic device sends the encapsulation message to the target access point through the data link between the first virtual client and the first access point and the backbone networks of the first access point and the target access point, the target access point receives the encapsulation message and sends the feedback message agreeing to be associated to the electronic device through the backbone networks of the first access point and the target access point and the data link between the first virtual client and the first access point, so that message interaction is completed, and the data link between the second virtual client and the target access point can be established.
S302, the electronic device determines a data link between the second virtual client and the second access point according to the data link between the second virtual client and the target access point.
Specifically, the second access point is one of the target access points.
In this embodiment of the present application, the data link between the second virtual client and the second access point may be determined according to the parameter of the data link between the second virtual client and the target access point. Wherein, the parameters of the data link include: data quality of the data link, throughput of the number link, reliability of the data link, signal strength, etc.
In this embodiment of the present application, the data link between the second virtual client and the second access point may be determined according to any parameter of the parameters of the data link, and the signal strength is exemplified in this embodiment of the present application.
For example, when the target access point is single, when the signal strength of the electronic device and the target access point is greater than the signal strength of the electronic device and the first access point, the data link between the second virtual client and the target access point is determined as the data link between the second virtual client and the second access point.
For example, when the number of the target access points is multiple, when the signal strength of the electronic device and one of the multiple target access points is greater than the signal strength of the electronic device and the first access point, the data link between the second virtual client and the one of the multiple target access points is determined as the data link between the second virtual client and the second access point.
S202, the electronic equipment performs data communication with the second access point according to the data link between the second virtual client and the second access point.
Specifically, in order to reduce the roaming switching time in the embodiment of the present application, when a channel when the electronic device communicates with the first access point is the same as a channel when the electronic device communicates with the second access point, referring to fig. 5, a method for the electronic device to perform data communication with the second access point according to a data link between the second virtual client and the second access point is provided, and fig. 5 is a schematic flowchart of a method for the electronic device to perform data communication with the second access point according to the embodiment of the present application. The execution subject of the method in fig. 5 may be the electronic device 300 in fig. 1. As shown in fig. 5, the method includes: s501 to S502.
S501, enabling a data link between a second virtual client and a second access point by the electronic equipment.
Specifically, in order to reduce the roaming time, the embodiment of the present application defines a sequence of enabling the data link between the second virtual client and the second access point and disabling the data link between the first virtual client and the first access point of the electronic device.
In the embodiment of the application, the data link between the second virtual client and the second access point is started first, and then the data link between the first virtual client and the first access point is stopped.
For example, please refer to table 1, where table 1 lists the time delay of receiving a message when the roaming method of the embodiment of the present application and the existing roaming method roam.
In table 1, the co-channel represents a channel when the electronic device communicates with the first access point, and is the same as a channel when the electronic device communicates with the second access point. When roaming is performed, the time delay for receiving the message is in the range of 0 to 4ms, and in the conventional roaming method, when the channel is the same, the time delay for receiving the message is in the range of 42 to 53ms, so that it can be known that the time delay for receiving the message by the roaming method of the embodiment of the present application is far less than the time delay for receiving the message by the conventional roaming method, and therefore the roaming time consumption of the roaming method of the embodiment of the present application is far less than the roaming time consumption of the conventional roaming method, and the internet experience of the user is improved.
TABLE 1
S502, after the electronic device starts the data link between the second virtual client and the second access point, the electronic device stops the data link between the first virtual client and the first access point.
In this embodiment of the present application, in order to reduce the time consumption for switching the channel too much, when a channel when the electronic device communicates with the first access point is different from a channel when the electronic device communicates with the second access point, referring to fig. 6, a method for the electronic device to perform data communication with the second access point according to a data link between the second virtual client and the second access point is provided, and fig. 6 is a schematic flowchart of a method for the electronic device to perform data communication with the second access point according to the embodiment of the present application. The execution subject of the method in fig. 6 may be the electronic device 300 in fig. 1. As shown in fig. 6, the method includes: s601 to S603.
S601, the electronic device disables the data link between the first virtual client and the first access point.
Specifically, in the embodiment of the present application, in order to reduce the time consumption for switching the channel, the data link between the first virtual client and the first access point is first disabled, and then the data link between the second virtual client and the second access point is enabled.
For example, please refer to table 1, in table 1, different channels represent channels when the electronic device communicates with the first access point, and are different from channels when the electronic device communicates with the second access point, and when the channels are different, the application first disables the data link between the first virtual client and the first access point, switches the channels when the electronic device communicates with the first access point to signals of the electronic device and the second access point, and then enables the data link between the second virtual client and the second access point. When roaming is performed, the time delay for receiving the message is within a range of 9 to 14ms, and when the channels are different in the conventional roaming method, the time delay for receiving the message is within a range of 53 to 67ms, so that it can be known that the time delay for receiving the message by the roaming method in the embodiment of the present application is far less than the time delay for receiving the message by the conventional roaming method, and therefore, the time consumed for switching the channel by the roaming method in the embodiment of the present application is far less than the time consumed by the conventional roaming method, and the time consumed by roaming by the roaming method in the embodiment of the present application is far less than the time consumed by roaming by the conventional roaming method, thereby improving the internet experience of the user.
S602, after deactivating the data link between the first virtual client and the first access point, the electronic device switches a channel when the electronic device communicates with the first access point to a channel between the electronic device and the second access point.
And S603, enabling a data link between the second virtual client and the second access point.
In order to ensure that data is not lost in the roaming process and improve the internet surfing experience of the user, the following method is adopted in the embodiment of the present application, and please refer to fig. 7, where fig. 7 is a schematic flow chart of a method for ensuring that data is not lost in the roaming process provided in the embodiment of the present application. The execution subject of the method in fig. 7 may be the electronic device 300 in fig. 1. As shown in fig. 7, the method includes: s701 to S702.
S701, before the electronic device starts a data link between the second virtual client and the second access point, obtaining a first data message sent by the electronic device, and storing the first data message.
Specifically, after determining a data link between the second virtual client and the second access point, the electronic device obtains a data packet sent by the electronic device before starting the data link between the second virtual client and the second access point, where the electronic device sends a packet to the second access point, which may also be referred to as an uplink packet.
In order to ensure that data is not lost in the roaming process, the uplink message is stored in the electronic equipment.
S702, after the data link between the second virtual client and the second access point is enabled, the electronic device sends a first data message to the second access point.
For example, referring to table 1, after the method shown in fig. 7 is adopted, when the roaming method according to the embodiment of the present application sends an uplink packet, there is no phenomenon of data packet loss, and compared with the existing roaming method, when the uplink packet is sent, there are two phenomena of occasional packet loss and inevitable packet loss, which improves the internet experience of the user.
Referring to fig. 8, fig. 8 is a schematic flow chart of another method for ensuring that data is not lost during roaming according to the embodiment of the present application. The execution subject of the method in fig. 8 may be the electronic device 300 in fig. 1. As shown in fig. 8, the method includes: s801 to S802.
S801, before enabling a data link between the second virtual client and the second access point, the electronic device stores the second data packet through the second access point.
Specifically, after determining the data link between the second virtual module and the second access point, and before starting the data link between the second virtual client and the second access point and the data link between the second virtual client and the second access point, the electronic device stores a second data message through the second access point, where the second data message is a data message sent to the electronic device by the first access point, and the second data message may also be referred to as a downlink message.
S802, after the data link between the second virtual client and the second access point is enabled, the electronic device receives a second data message sent by the second access point.
For example, referring to table 1, after the method in fig. 8 is adopted, when the roaming method in the embodiment of the present application sends a downlink packet, there is no phenomenon of data packet loss, and compared with the existing roaming method, when sending a downlink packet, there are two phenomena of packet loss and inevitable packet loss occasionally, which improves the internet experience of the user.
In summary, in the technical solution of the present application, when a first virtual client associates with a first access point, a data link between a second virtual client and a second access point is determined; and the electronic equipment performs data communication with the second access point according to the data link between the second virtual client and the second access point.
