Abstract

A method includes a first electronic device that detects a signal strength when the first electronic device communicates with a second electronic device, and determines whether the signal strength is less than a preset value. When the signal strength is less than the preset value, the first electronic device determines a current service state of the second electronic device, and determines, based on the current service state, working modes including a first working mode and a second working mode that respectively correspond to the first electronic device and the second electronic device and that are suitable for the current service state. The first electronic device switches a working mode of the first electronic device to the determined first working mode, and sends an instruction to indicate to the second electronic device to switch a working mode of the second electronic device to the second working mode.

when the signal strength is less than the first preset value;
determining a current service state of the second electronic device; and
determining, based on the current service state, working modes that respectively correspond to the first electronic device and the second electronic device and that are suitable for the current service state, wherein determining the working modes comprises at least one of:
determining that the first electronic device and the second electronic device are in a third mode when the current service state is a first service state, wherein the third mode is sending and receiving data on the 2.4G frequency band and the 5G frequency band;
determining that the first electronic device is in a fifth mode and the second electronic device is in a fourth mode when the current service state is a second service state, wherein the fifth mode is sending data on the 5G frequency band and receiving data on the 2.4G frequency band, and wherein the fourth mode is sending data on the 2.4G frequency band and receiving data on the 5G frequency band; and
determining that the first electronic device is in the fourth mode and the second electronic device is in the fifth mode when the current service state is a third service state;

switching the first electronic device from the first mode or the second mode to a first determined mode that corresponds to the first electronic device, wherein the first determined mode is one of the third mode, the fourth mode, or the fifth mode; and
sending a first instruction to indicate to the second electronic device to switch from the first mode or the second mode to a second determined mode that corresponds to the second electronic device,

wherein the second determined mode is one of the third mode, the fourth mode, or the fifth mode.

2. The wireless data transmission method of claim 1 , further comprising determining whether the current service state is the first service state, wherein the first service state comprises that a current service of the second electronic device is a preset service, and wherein the preset service is a game service or a voice service.

3. The wireless data transmission method of claim 1 , further comprising at least one of:
determining, using a format of a data frame, whether the current service state is the first service state; or
determining, using a data throughput, whether the current service state is one of the second service state or the third service state.

6. The wireless data transmission method of claim 1 , wherein after switching the first electronic device and sending the first instruction, the wireless data transmission method further comprises:
detecting whether communication quality is improved;
maintaining the first determined mode to perform data transmission when the communication quality is improved; and
performing when the communication quality does not improve:
switching the first determined mode to the first mode or the second mode; and
sending a second instruction to indicate to the second electronic device to switch the determined mode to the first mode or the second mode.

7. The wireless data transmission method of claim 1 , further comprising determining whether the current service state is one of the second service state or the third service state, wherein the second service state comprises that an uplink service volume is greater than a downlink service volume, and wherein the third service state comprises that the downlink service volume is greater than the uplink service volume.
