Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a link selection method according to an embodiment of the present application, applied to the electronic device shown in fig. 1, where the link selection method includes:
s201, when the electronic equipment detects a multilink starting request, the electronic equipment determines state information of a plurality of communication links to be connected.
The electronic device may specifically detect the multi-link initiation request, which may be an enabling request for the link aggregation function, or may detect an execution operation for enabling the link aggregation function, which is not limited herein.
The specific implementation manner of detecting the multilink start request may also be detecting a start operation for a multilink start request key, or detecting that a speed of current data transmission is lower than a preset speed threshold, and the like, which is not limited herein.
The status information may be various, and for example, may include the number of currently connected devices of each communication link, or may be the channel quality of each communication link, or may be the data transmission frequency, the data transmission rate, and the like of each communication link, which is not limited herein.

S202, the electronic equipment selects at least two target communication links in the plurality of communication links according to the state information.
The specific implementation manner of selecting at least two target communication links of the multiple communication links according to the state information may be various, for example, at least two target communication links with the best channel quality may be selected according to the channel quality of each communication link, or at least two target communication links with a smaller number of connected devices may be selected according to the number of connected devices of each communication link, which is not limited herein.
Wherein, the channel quality can be calculated according to the channel of the communication link, and the channel quality includes the capacity of the channel itself, the network speed, the network delay, etc.
S203, the electronic equipment is connected with the at least two target communication links.
It can be seen that, in the embodiment of the present application, when the electronic device detects a multilink start request, the electronic device determines state information of a plurality of communication links to be connected, selects at least two target communication links of the plurality of communication links according to the state information, and finally connects the at least two target communication links. Therefore, after the electronic equipment starts the multilinks, at least two target communication links are selected according to the state information of each communication link to be connected to transmit the data packets, and compared with a traditional link selection method, the link selection method can improve the reasonability and effectiveness of link selection, and meanwhile, compared with the method that data are transmitted through one communication link, the data transmission speed can be improved, the time consumed by data transmission is reduced, the network delay is reduced, and the data transmission efficiency of the electronic equipment is improved.
In one possible example, the determining the state information of the plurality of communication links to be connected when the multilink start request is detected includes:
when a multilink starting request is detected, determining data types of a plurality of data transmission tasks to be processed;
determining the types of the state information of the plurality of communication links to be connected according to the data types of the plurality of data transmission tasks;
and determining the state information of the plurality of communication links to be connected, which is matched with the type of the state information.
The data types may include a first data type and a second data type, where the first data type is a data type that requires data transmission through a wired network (for example, a dedicated hotspot of the smart home device, Wi-Fi, and the like, that is, does not require data transmission through a cellular mobile communication network), and the second data type is a data type that requires data transmission through a cellular mobile communication network.
For example, the electronic device is a smart phone, and the plurality of data transmission tasks include a transmission task in which the smart phone uploads data to a smart home, for example, a transmission task in which a television is turned on, and the like, and correspond to a first data type, and also include a transmission task in which the smart phone transmits chat information to another smart phone, and correspond to a second data type.
For example, when the data type is a first data type, the determined type of the state information may be the number of devices connected to each communication link, or the channel quality of each communication link, and when the data type is a second data type, the determined type of the state information may be the data transmission frequency or the data transmission rate of each communication link, which is not limited herein.

The specific implementation manner of selecting at least two target communication links in the multiple communication links to be connected according to the data transmission rate of each communication link to be connected in the first preset time period may be to select at least two target communication links with the highest data transmission rate in the multiple communication links to be connected, or to select at least two target communication links with a data transmission rate higher than a preset rate threshold in the multiple communication links to be connected, which is not limited herein.
As can be seen, in this example, the electronic device determines the data transmission rate of each time period according to the historical connection record of each communication link to determine the target communication link connected in each time period, which is beneficial to improving the intelligence of link selection.
In one possible example, after the connecting the at least two target communication links, the method further comprises:
