Abstract

The invention provides a method for realizing communication between mobile terminals by use of FM. The method comprises the following steps: all available signal frequencies within a predetermined range in the surrounding area are scanned, and the signal frequency parameters of the signal frequencies are acquired; the signal frequency parameter of an interactive mobile terminal communicating with a target mobile terminal is acquired; a shared signal frequency of the target mobile terminal and the interactive mobile terminal in transmitting / receiving is calculated according to the signal frequency parameter of the target mobile terminal and the signal frequency parameter of the interactive mobile terminal; and frequency-modulation FM signal communication with the interactive mobile terminal is realized by use of the shared signal frequency. According to the invention, the signal equality of a signal frequency at which each mobile terminal receives or transmits a radio frequency signal is enabled to be at a most appropriate level. The problem that the signal quality is poor when some mobile terminals receive a radio frequency signal is solved.

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and mobile terminal for realizing communication between mobile terminals using FM. Background technique [0002] Mobile terminals such as mobile phones play an increasingly important role in people's daily life, and the functions of mobile terminals are becoming more and more abundant. [0003] In the prior art, mobile terminals such as mobile phones of certain models have an FM transmission function. The mobile terminal with transmitting function scans the idle signal frequency, and transmits FM signal through this idle signal frequency. The idle signal frequency mentioned here is the signal frequency scanned by the mobile terminal that is not occupied by the radio station. Radio frequency receiving equipment such as FM radio receives and broadcasts. [0004] There are many idle frequency points. Because there are many signal sources for mobile terminals, touch pan...
