1. A mobile terminal, comprising:

  • a central processor, a fixed network access control module, a frequency shift keying processing module, a call processing module, a mobile communication module and an electronic switch module, whereinthe fixed network access control module is connected with the central processor, comprises an analogue subscriber line interface, and is configured to connect the mobile terminal and an analogue subscriber line, and to notify the central processor that the mobile terminal is connected with a fixed telephone network when the analogue subscriber line is connected with the analogue subscriber line interface;

    the frequency shift keying processing module is connected with the central processor, and is configured to identify a signaling from the connected analogue subscriber line and send the signaling from the connected analogue subscriber line to the central processor, and to identify a signaling from the central processor and send the signaling from the central processor to the connected analogue subscriber line;

    the call processing module is configured to extract a voice signal from the analogue subscriber line and send the voice signal from the analogue subscriber line to a voice output device of the mobile terminal to be played, and to send a voice signal from a user to the analogue subscriber line;

    the mobile communication module is configured to achieve communication between the mobile terminal and outside based on a radio network; and

    the central processor is configured to process a signaling from the frequency shift keying processing module and send a signaling to be transmitted by the analogue subscriber line to the frequency shift keying processing module, and to control the electronic switch module to close a radio frequency sending/receiving function of the mobile communication module when the fixed network access control module notifies the central processor that the mobile terminal is connected with the fixed telephone network.
