Method and device for detecting abnormality of radio frequency path of terminal equipment

Abstract

The invention discloses a detection method and a detection device for the abnormity of a radio frequency circuit of terminal equipment. The method comprises the steps of acquiring a radio frequency quality parameter value of N resident cells of each piece of terminal equipment of the M pieces of terminal equipment having a same model, thus acquiring M*N radio frequency quality parameter values; performing mathematical statistic treatment on the M*N radio frequency quality parameter values, thus acquiring a discrete type probability distribution function F(x), wherein x is the radio frequency quality parameter value; acquiring the abnormal probability P(E) of a radio frequency circuit device E in the terminal equipment having the same model with the M pieces of terminal equipment; and sending information including F(x) and P(E) to the terminal equipment to be detected having the same model with the M pieces of terminal equipment, wherein the information is applied to the terminal equipment to be detected for detecting whether the radio frequency circuit is abnormal. According to the method and the device provided by the invention, detection on the abnormity of the radio frequency circuit of the terminal equipment can be achieved without either the additional professional test equipment or the complex professional operation, knowledge and skills, so that material and manpower resources are saved, and thus the detection cost is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for detecting an abnormal radio frequency path of terminal equipment. Background technique [0002] With the rapid development of modern communication technologies, terminal devices with radio frequency access functions have been widely used in various fields of people's lives. The radio frequency path in the terminal equipment is mainly used to transmit and receive communication signals. The current radio frequency path includes transceivers, power amplifiers, duplexers, impedance matching networks, couplers, and feedback paths. During the process of transmitting signals, the The transceiver generates a low-power transmission signal, amplifies the low-power transmission signal through the power amplifier, and then transmits it to the coupler through the duplexer. The coupler couples the transmission signal and obtains two output signals, one of...
