5 GHz (Gigahertz, GHz) wireless fidelity (wireless-fidelity, Wi-Fi) refers to operating in the 5GHz (5150MHz-5825MHz) radio wave frequency band, and uses the Institute of Electrical and Electronics Engineers (institute for electrical and electronic engineers, IEEE) Standard Wi-Fi. As the 2.4G frequency band used by the Wi-Fi network becomes more and more crowded and cannot meet the development needs, countries have successively opened up the 5G frequency band. Compared with 2.4G Wi-Fi, 5G Wi-Fi has a higher wireless transmission speed. Exemplarily, the 2.4G channel and 5G channel information involved in different Wi-Fi standards stipulated by IEEE may be shown in Table 1:

Table 1

At present, 5G Wi-Fi channels are mostly used by the military and civilians, and the development situation is complicated. For example, the 5G Wi-Fi channels opened in different regions are different; the 5G Wi-Fi channel regulations of different countries will also change with time; The channels are divided into indoor channels and outdoor channels. Some countries stipulate that indoor channels cannot be used by equipment working outdoors, etc. Different regulations make the availability of 5G Wi-Fi channels different in different countries at different times and in different scenarios.

When replacing and cloning between old and new devices, if the amount of data to be backed up is large, using the 5G frequency band for data transmission will greatly improve the efficiency of data transmission. Considering the complexity of the availability of the 5G frequency band, when performing data cloning in the 5G frequency band, it is necessary for the old and new devices to negotiate and determine a consistent 5G channel for interaction. In a possible implementation, the old and new devices can select a channel from the intersection of 5G channels jointly supported by both parties to interact, so as to realize data cloning on the 5G frequency band. This process can be specifically referred to the flowchart shown in FIG. 1 .

Exemplarily, as shown in FIG. 1 , it is a schematic flowchart of data transmission between old and new devices. The process includes the following steps:

S101(a), the new device queries the list of supported 5G channels;

S101(b), the old device queries the list of supported 5G channels;

S102, the old device sends a list of 5G channels supported by the old device to the new device;

S103, the new device compares whether the 5G channel lists supported by the new device and the old device overlap;

The comparison result in this step has two cases: case 1, the channels of the two parties have intersection; case 2, the channels of the two parties have no intersection. in:

If the comparison result is situation 1, execute step S104, that is, the new device and the old device perform data transmission on the 5G channel supported by both parties;

If the comparison result is situation 2, then step S105 is performed, that is, the new device and the old device perform data transmission on the 2.4G channel.

The data transmission process shown in Figure 1 above can be implemented through the application (application, App) installed on the new device and the old device (such as a cloned application), and this process needs to be able to obtain the list of 5G channels supported by the old device before the cloned application ( or collections) based on implementation. However, in practical applications, some systems do not provide a standard interface for the 5G channel of the chip. At this time, if the cloned application installed on the old device is a third-party app, the cloned application cannot query the list of 5G channels supported by the old device. It is also impossible to confirm the 5G channels supported by both parties by comparing the channel list between the device and the old device.

In view of the above problems, the embodiment of the present application provides a method of data transmission. In this method, when the list of 5G channels supported by the old device cannot be known, the new device tries to connect the 5G channels supported by itself with the peer end according to the preset rules. Establish a Wi-Fi connection, thereby improving the possibility of clone data transmission between old and new devices on the 5G channel, and improving user experience.
