It can be understood that the period may be set according to an actual application scenario, and the embodiment of the present invention does not limit the period.
In practical application, whether the power amplifier, the main antenna switch and the auxiliary antenna switch are abnormal or not can be determined by reading configuration information of the power amplifier, the main antenna switch and the auxiliary antenna switch.

The embodiment of the invention can periodically read the PID and MID information, thereby detecting whether the power amplifier is abnormal. In practical application, a smaller value is set in a reading period, so that whether the power amplifier is abnormal or not can be detected as early as possible; if the read cycle is set to a large value, the later the abnormality of the power amplifier is detected, which may result in a problem that the communication abnormality cannot be solved as quickly as possible.
