METHOD AND MOBILE PHONE CAPABLE OF AUTOMATICALLY SWITCHING RADIO CHANNELS OF A FREQUENCY MODULATION RADIO
First Claim
1. A method for automatically switching radio channels of a frequency modulation (FM) radio within a mobile phone, the method comprising:
- receiving analog signals broadcasted by a base transceiver station via a first antenna, and receiving wireless broadcast signals via a second antenna, wherein the analog signal comprises local area identity (LAI) information of a local area of where the mobile phone is located;
converting the analog signals to digital signals;
reading the LAI information from the analog signals;
searching a channel database to retrieve available radio channel information in the local area based on the LAI information;
displaying radio station names corresponding to a selected radio channel;
playing radio broadcast broadcasted by the selected radio station according to the wireless broadcast signals, and synchronously monitoring if the LAI information changes;
determining if the FM radio needs to switch the selected radio channel to an available radio channel upon the condition that the LAI information changes;
automatically switching the FM radio to the available radio channel upon the condition that the FM radio needs to switch the selected radio channel to the available radio channel; and
playing the radio broadcast based on the available radio channel.

Abstract
A mobile phone capable of switching radio channels of an FM radio is provided. The mobile phone includes antennas for receiving analog signals and wireless signals. The mobile phone includes a signal conversion module for converting the analog signals to digital signals, and a channel database for storing radio channel information corresponding to LAI information of different local areas. A communication protocol processing module of the mobile phone is configured for receiving the digital signals, and for reading the LAI information of a local area where the mobile phone is located. A FM management module of the mobile phone is configured for searching the channel database to retrieve available radio channel information in the local area, synchronously monitoring if the LAI information changes, and determining if the FM radio needs to switch from one radio channel to another radio channel.
