The invention provides a terminal control method and a terminal. The terminal control method comprises the following steps: acquiring a network
frequency band currently working on the terminal; under the condition that the terminal works in the first
frequency band of the first network and the second
frequency band of the second network at the same time, determining whether the first frequency band generates
harmonic interference on the second frequency band; under the condition that the first frequency band generates
harmonic interference on the second frequency band, accessing a
harmonic filtering unit into a first
radio frequency path of the first network; and / or switching the first antenna connected with the first
radio frequency path and / or switching the second antenna connected with the second
radio frequency path. According to the embodiments of the present invention, when a first frequency band and a second frequency band which work at the same time generate
harmonic interference, a
harmonic filtering unit is accessed to a first radio frequency path of the first network under the control of the second radio frequency path, to filter out second
harmonics of a first frequency band, or improve the isolation between access antennas of the two radio frequency paths, so as to reduce or eliminate the
harmonic interference of the first frequency band on a second frequency band, and effectively guaranteeing the receiving effect of the second network.
