Example Embodiment

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027]In the prior art, when using a dual-mode mobile terminal, the network operator will continuously send broadcast control information to each user in the cell through the network system. The information includes the carrier frequency of the broadcast control channel. When the dual-mode mobile terminal is turned on , the two sets of RF front-ends of the dual-mode mobile terminal will respectively use the antennas connected to them to receive broadcast contro...

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...
