Mobile terminal and antenna switching method and device thereof

Abstract

An embodiment of the invention provides a mobile terminal and an antenna switching method and device thereof and relates to the technical field of communication. By the aid of the antenna switching method and device, radiation hazards to humans when a first antenna at the top of the mobile terminal receives and transmits low-frequency signals are reduced, interference to the humans from the first antenna is reduced, and influence on communication quality from the interference is alleviated. The antenna switching method includes detecting whether transceiving signals of the first radio frequency front end are low-frequency signals or not when in voice communication through the first radio frequency front end and a receiver, and when the transceiving signals of the first radio frequency front end are low-frequency signals, switching the antenna providing the transceiving signals for the first radio frequency front end as a second antenna which is the antenna at the bottom of the mobile terminal. The antenna switching method and device in the embodiment is used for antenna switching of the mobile terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal antenna switching method, device and mobile terminal. Background technique [0002] With the development of communication technology, mobile communication has gradually evolved from 2G (2-Generation wireless telephone technology, second-generation wireless telephone technology) to 3G (3rd Generation, third-generation mobile communication technology) and gradually developed to 4G (the 4 Generation mobile communication technology, the fourth generation mobile communication technology), from the original GSM (global system for mobile communication, global system for mobile communication, global system for mobile communication, GSM900 and GSM1800 two frequency bands evolved to now need to support TD-LTE (Time Division- Long Term Evolution, Time Division Long Term Evolution), FDD-LTE (Frequency Division Duplex-Long Term Evolution, Frequency Division Du...

AI Technical Summary

Problems solved by technology

When the first radio frequency front end 201 transmits and receives low-frequency signals through the first antenna 203 for voice calls, since the first antenna 203 is located at the top of the dual-mode mobile terminal 20, and the low-frequency signal power is large, when the dual-mode mobile terminal 20 uses a handset for voice calls , the low-frequency signals sent and received by the first RF front-end 201 will cause greater radiation hazards to the human body

At the same time, due to the long wavelength of the low-frequency signal, when the human body approaches, the first antenna 203 for sending and receiving the low-frequency signal is easily interfered, which in turn causes the problem of poor voice communication quality
