Abstract

The invention provides a method for quickly switching a frequency point, a device for quickly switching the frequency point and a mobile terminal. The method includes the following steps that: after acell is searched, a first system message sent by a base station where the cell is located is received; the first system message is parsed; a second system message sent by the base station where the cell is located is received after the first system message is successfully parsed; the second system message is parsed, wherein the second system message contains an MFBI indication and a correspondingfrequency point number; and when the MFBI indication indicates that the frequency point number needs to be switched, the current frequency point number is switched to a corresponding frequency pointnumber, otherwise, the current frequency point number is maintained. The method and device of the invention can reduce the complexity of frequency point switching, is not prone to making mistakes, andhas high robustness.

Description

technical field [0001] The present invention relates to the technical field of network switching, in particular to a method, device and mobile terminal for quickly switching frequency points. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) project is the evolution of 3G. The LTE system defines FDD (Frequency Division Duplex, frequency division duplex) and TDD (Time Division Duplex, time division duplex). It improves and enhances the 3G Its air access technology adopts OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple-Input Multiple-Output) technologies as the only standards for its wireless network evolution. [0003] The TDD LTE frequency band is allocated to three operators in China, Band38 range: 2570-2619.9MHz is assigned to China Mobile, and the corresponding frequency point number is 37750-38249. Band41 is a large frequency band, including the frequency of Band38, the range is: 2496-2690MHz. But in addition to Band3...
