In an embodiment of the present application, referring to fig. 3, fig. 3 is a schematic flowchart of a method for determining a data link between a second virtual client and a second access point according to an embodiment of the present application. The subject of the method of fig. 3 may be the electronic device 300 of fig. 1. As shown in fig. 3, the method includes: s301 to S302.
S301, the electronic equipment establishes a data link between the second virtual client and the target access point.
Specifically, the target access point is an access point that is not associated with the electronic device. The number of the target access points is not limited in the embodiment of the application.
In the embodiment of the application, when the electronic equipment performs data communication with the first access point through the first virtual client, a data link between the electronic equipment and the target access point is established in advance through the second virtual client.
Illustratively, when only a single target access point exists in the network, a data link with the single target access point is previously established by 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, at which point the electronic device configures a plurality of virtual clients, such as: the electronic device may establish a data link with the target access point 1 through the virtual client 1, 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 either the target access point 2 or 3, and embodiments of the present application are not limited to establishing a data link with a particular virtual client with a particular target access point.
In the embodiment of the present application, referring to fig. 4, 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. The subject of the method of fig. 4 may be the electronic device 300 of fig. 1. As shown in fig. 4, the method includes: s401 to S402.
S401, the electronic equipment encapsulates the association message of the second virtual client and the target access point to obtain an encapsulated message.
Specifically, in the embodiment of the present application, the association message between the second virtual client and the target access point is encapsulated by a private protocol, where the association message includes: probe request message Rsp, identity authentication message Auth, association request message Assoc Req, key message EAPOL-Key, etc.
S402, the electronic equipment transmits the encapsulation message through the data link between the first virtual client and the first access point and the data transmission network between the first access point and the target access point, and establishes the data link between the second virtual client and the target access point.
Specifically, in the embodiment of the present application, the data transmission network between the first access point and the target access point, that is, the backbone network for transmitting data between the access point and the target access point, is a large-sized transmission network, which is used for connecting with a small-sized transmission network and transmitting data.
In the embodiment of the application, the electronic equipment sends the encapsulation message to the target access point through the data links of 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, sends the feedback message agreeing to be associated to the electronic equipment through the backbone networks of the first access point and the target access point and the data links of the first virtual client and the first access point, and completes message interaction, thus establishing the data links of the second virtual client and the target access point.
S302, the electronic equipment determines the 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 the embodiment of the application, the data link between the second virtual client and the second access point can be determined according to the parameters 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 data links, throughput of number of links, reliability of data links, signal strength, etc.
In the embodiment of the present application, the data link between the second virtual client and the second access point may be determined according to any one of the parameters of the data link.
For example, when the target access point is single, the data link between the second virtual client and the target access point is determined to be the data link between the second virtual client and the second access point when the signal strength between the electronic device and the target access point is greater than the signal strength between the electronic device and the first access point.
For example, when the number of target access points is plural, when the signal strength of the electronic device and one of the plurality of 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 plurality of target access points is determined to be 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, 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, according to a data link between the second virtual client and the second access point, a method for performing data communication between the electronic device and the second access point is shown in fig. 5, and fig. 5 is a schematic flowchart of a method for performing data communication between the electronic device and the second access point provided in the embodiment of the present application. The subject of the method of fig. 5 may be the electronic device 300 of fig. 1. As shown in fig. 5, the method includes: s501 to S502.
S501, the electronic device enables a data link between the second virtual client and the second access point.
Specifically, in order to reduce roaming time, the embodiment of the application limits the 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 for 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, in which the roaming method according to the embodiment of the present application and the time delay of the received message when the existing roaming method roams are listed in table 1.
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, and when the channels are the same, the present application enables the data link between the second virtual client and the second access point, and then disables the data link between the first virtual client and the first access point. When roaming is carried out, the time delay of receiving the message is in the range of 0 to 4ms, and in the existing roaming method, when channels are the same, the time delay of receiving the message is in the range of 42 to 53ms, so that the time delay of receiving the message by the roaming method of the embodiment of the application is far less than the time delay of receiving the message by the existing roaming method, therefore, the roaming time consumption of the roaming method of the embodiment of the application is far less than the roaming time consumption of the existing roaming method, and the Internet surfing experience of users is improved.
TABLE 1
S502, the electronic device disables the data link between the first virtual client and the first access point after enabling the data link between the second virtual client and the second access point.
In order to reduce excessive time consumption for channel switching, when a channel when an electronic device communicates with a first access point is different from a channel when the electronic device communicates with a second access point, according to a data link between a second virtual client and the second access point, a method for data communication between the electronic device and the second access point is shown in fig. 6, and fig. 6 is a schematic flowchart of a method for data communication between the electronic device and the second access point according to an embodiment of the present application. The subject of the execution 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 equipment disables a data link between a first virtual client and a first access point.
Specifically, in the embodiment of the present application, in order to reduce excessive time consumption for channel switching, 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 from each other, the data link between the first virtual client and the first access point is first deactivated, and after the channels when the electronic device communicates with the first access point are switched to signals between the electronic device and the second access point, the data link between the second virtual client and the second access point is activated. When roaming is carried out, the time delay of the received message is in the range of 9 to 14ms, and when the channels are different in the existing roaming method, the time delay of the received message is in the range of 53 to 67ms, so that the time delay of the received message in the roaming method of the embodiment of the application is far less than the time delay of the received message in the existing roaming method, the time consumption of switching channels in the roaming method of the embodiment of the application is far less than the time consumption of the existing roaming method, and the time consumption of roaming in the roaming method of the embodiment of the application is far less than the time consumption of roaming in the existing roaming method, and the Internet surfing experience of users is improved.
S602, after the electronic device disables the data link between the first virtual client and the first access point, switching the channel when the electronic device communicates with the first access point to the channel between the electronic device and the second access point.
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 the internet experience of a user is improved, the following method is adopted, and referring to fig. 7, fig. 7 is a schematic flow chart of the method for ensuring that data is not lost in the roaming process, which is provided by the embodiment of the application. The subject of the execution 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 equipment starts a data link between the second virtual client and the second access point, acquiring a first data message sent by the electronic equipment, and storing the first data message.
Specifically, after determining the data link between the second virtual client and the second access point, the electronic device acquires a data packet sent by the electronic device before enabling the data link between the second virtual client and the second access point, where the electronic device sends a packet, which may also be referred to as an uplink packet, to the second access point.
In order to ensure that data is not lost in the roaming process, the embodiment of the application stores the uplink message in the electronic equipment.
S702, the electronic device sends a first data message to the second access point after enabling the data link between the second virtual client and the second access point.
For example, referring to table 1, after the method of fig. 7 is adopted, when the roaming method of the embodiment of the present application sends an uplink packet, there is no phenomenon of losing a data packet, 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, so as to improve the internet experience of the user.
Referring to fig. 8, fig. 8 is a schematic flow chart of another method for guaranteeing data not to be lost in roaming according to an embodiment of the present application. The subject of the execution 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, the electronic device stores a second data message through a second access point before enabling a data link between the second virtual client and the second access point.
Specifically, after determining the data link between the second virtual module and the second access point, the electronic device stores, through the second access point, a second data packet, which is a data packet sent by the first access point to the electronic device, before enabling 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, where the second data packet may also be referred to as a downlink packet.
S802, after enabling a data link between the second virtual client and the second access point, the electronic device receives a second data message sent by the second access point.
For example, referring to table 1, after the method of fig. 8 is adopted, the roaming method in the embodiment of the present application does not have the phenomenon of losing the data packet when sending the downlink message, and compared with the existing roaming method, when sending the downlink message, the roaming method can occasionally have the phenomenon of losing the data packet and the phenomenon of inevitably losing the data packet, thereby improving the internet experience of the user.
