Step 401, the terminal device adjusts the handover parameters in the first handover parameter set according to the application type to obtain a second handover parameter set.
In the embodiment of the present invention, the terminal device may adjust the switching parameter corresponding to the application type in the first switching parameter set according to the application type, so as to obtain the second switching parameter set.
Optionally, in this embodiment of the present invention, if the application type is a video type, a call type, or a shopping type, the terminal device may adjust RSRP, SNR, and/or throughput in the first handover parameter set to obtain the second handover parameter set.
Optionally, in this embodiment of the present invention, if the application type is a game type, the terminal device may adjust a time delay and/or a BER in the first switching parameter set to obtain the second switching parameter set.
Optionally, in the embodiment of the present invention, when the handover parameter in the first handover parameter set meets a preset rule (for example, the time delay is greater than a preset value, or the BER is greater than a preset value), the terminal device may adjust the handover parameter in the first handover parameter set.
For example, if the initial setting is that the RSRP is lower than the threshold value by-90 to perform the antenna switching, in a game scenario, the time delay needs to be as small as possible, that is, it is to be ensured that the antenna switching is not so frequent as possible, and according to an actual scenario, the terminal device may decrease the threshold value by 3 steps (that is, -90) until the threshold value is lower than-100. In a video scene or a call scene, the terminal device may increase the threshold value by setting the step length to 1, so that the antenna is switched to a good antenna as much as possible, thereby ensuring throughput and call quality.
Step 402, the terminal device updates the first switching parameter set stored in the terminal device to the second switching parameter set.
In the embodiment of the present invention, since the terminal device may adjust the switching parameter in the first switching parameter set according to the application type to update the first switching parameter set (updated to the second switching parameter set), that is, update the reference parameter during antenna switching, the antenna parameter of the antenna after switching may further satisfy the switching parameter in the second switching parameter set, so that the antenna after switching may ensure the transmission performance of the terminal device.
