PURPOSE:To switch a call by depressing a hook switch for short time when the other call is received during that a codeless telephone mobile station is in call in the mobile station having a transmitter-receiver and a hook switch. CONSTITUTION:When the hook switch 19 is depressed during the call, a hook switch depression counting means 20 starts the counting of depression time. When depression time is longer than prescribed time T, line wire termination data is generated in a transmission data generating means 10 and line wire termination data is sent from a transmission antenna 17 and a system returns to a standby state. When depression time is shorter than prescribed time T, the data generating means 10 generates the hook data for closing the line wire again after it is opened for prescribed time. Then, the hook data is sent from the transmission antenna 17 through an RF transmission circuit 11 so as to maintain the line wire call. |
