The invention discloses a faulty frequency band processing method. The method comprises the following steps: when a faulty frequency band detection instruction is detected, determining the transmitting power of each to-be-detected frequency band, for each frequency band in the frequency bands, determining whether the frequency band is a faulty frequency band according to the transmitting power of the frequency band and the power of a feedback signal acquired by sending signals based on the transmitting power of the frequency band, and when the frequency band is determined as the faulty frequency band, shielding the frequency band. The invention further discloses a faulty frequency band processing apparatus. By means of the manner of detecting the faulty frequency band and shielding the faulty frequency band, a mobile terminal will not use the faulty frequency band, thereby effectively avoiding the influence to the network search speed and the cell handover caused by using the faulty frequency band, and avoiding the problem of waste of electric quantity caused by using the faulty frequency band.
Description
technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and device for processing faulty frequency bands. Background technique [0002] At present, there are many kinds of radio frequency channels for mobile terminals, for example: Global System for Mobile Communication (Global System for Mobile Communication, GSM) radio frequency channel, Code Division Multiple Access (CDMA) radio frequency channel, Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, WCDMA) radio frequency channel, time division synchronous code division multiple access (Time Division-Synchronous Code Division Multiple Access, TDSCDMA) radio frequency channel, long term evolution (Long Term Evolution, LTE) radio frequency channel. For any mobile terminal, one or more radio frequency channels mentioned above may be included. [0003] Wherein, for any radio frequency channel mentioned above, there is at least one f...
