PROBLEM TO BE SOLVED: To prevent the portability of a mobile station terminal and a data terminal from being lowered by constituting the mobile station terminal so as to execute data access to the data terminal through a receiving circuit and a transmitting circuit. SOLUTION: A mobile station terminal 100 is connected to a base station 10 through a radio wave and the base station 10 is connected to a public telephone network 30 through an exchange 20. A transmitting voice signal is transmitted/received among the terminal 100, the station 10 and the network 30. In the case of accessing data from a data terminal 200, the terminal 200 is connected to the terminal 100 through an infrared-ray interface. Connection relation between the terminal 100 and the network 30 is similar to the connection between the terminals 200, 100. Since data access can be attained without connecting the terminal 200 to another equipment through a cord or the like, the portability of the data terminal 200 and the mobile station terminal 100 can be prevented from being reduced. |
