ABSTRACT:
This invention provides a mobile communication system in which a call-incoming side can switch a communication line to an appropriate one which corresponds to a communication type requested by a transmitter's terminal. One example of its construction is as follows.
A mobile station has a plurality of terminal units corresponding to plural types of communication and a call number is preliminarily assigned to each of them. A terminal unit in a telephone network uses a call number corresponding to a desired communication type when a datum is transmitted to the mobile station. The mobile station informs this call number to all of the terminal units which are connected to the mobile station. The respective terminal units inform the communication type to the mobile station only when the communication type corresponding to the call number can be handled. The mobile station informs this communication type contained in a reception call receiving signal to a mobile communication exchange. The mobile communication exchange selects a modulated/demodulator corresponding to this communication type.
