BEAM SWITCHING METHOD, DEVICE, AND MOBILE TERMINAL

Provided are a beam switching method, a device, and a mobile terminal, pertaining to the technical field of communications. The method comprises: measuring, at every first pre-determined time interval, a current signal strength of a current beam connected to a base station; if the current signal strength is greater than a pre-determined lower limit strength threshold, determining, on the basis of a change amplitude of the current signal strength and beam space-time correlations of the current beam with respect to all beams of a mobile terminal, a maximum signal strength corresponding to multiple candidate beams selected from all of the beams, wherein the beam space-time correlations are associated with an environment around the mobile terminal and a motion state thereof; and performing, on the basis of the maximum signal strength and the current signal strength, a switching operation on the beam of the mobile terminal that is connected to the base station. The present invention alleviates the technical problem of the prior art in which beam joining is tedious and power consuming.
