Problems solved by technology

In this case, mobile phone search and cell switching will slow down, and some standard networks may even be unavailable in some areas, which reduces the communication efficiency of mobile terminals. However, users do not know that there is a hardware failure on the mobile phone, which seriously affects the user experience

Abstract

The invention discloses an RF fault detection method and device. The method comprises that emission powers of different emission links of a terminal are obtained; a directional coupler of the terminal is used to obtain corresponding coupling powers of the emission links; and an emission line with a fault is determined according to the emission powers and the corresponding coupling powers of the emission links. Thus, the different emission links are detected on the basis that hardware structure of a mobile terminal is not changed, the mobile terminal can find the emission link with faults timely, and the communication efficiency of the mobile terminal is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of terminals, and in particular, to a method and device for detecting radio frequency faults. Background technique [0002] Mobile terminals such as mobile phones send radio frequency signals to the base station through the transmission link to communicate with the base station or other mobile phones. Since the mobile phone is constantly moving, the distance between the mobile phone and the base station is constantly changing, so the transmission power of the mobile phone is not fixed. The distance is different, and the power level signal is sent to the mobile phone. After receiving the power level signal, the mobile phone will automatically adjust the transmission power. The transmission power is small when it is close to the base station, and the transmission power is high when it is far away from the base station. [0003] When the transmission link of certain frequency bands of mob...
