Summary:The invention, which relates to the technical field of mobile terminal communication, provides a frequency adjustment method and a mobile terminal. The frequency adjustment method comprises: when a mobile terminal can not realize network registration, a reference frequency for frequency adjustment by the mobile terminal is determined according to a signal received from a base station and a local oscillation frequency of the mobile terminal; on the basis of a preset adjustment step length, the reference frequency is adjusted; and according to the adjusted reference frequency, the signal received from the base station is demodulated and an operating frequency of the mobile terminal is determined. According to the invention, when the mobile terminal can not realize network registration, the frequency of the mobile terminal is adjusted based on the signal received from the base station and the local oscillation frequency; and the mobile terminal realizes information demodulation by using the adjusted frequency to
