Abstract
In a first aspect of the invention, when it is expected to disconnect a booster during a call, the station class mark is changed to that applicable when a portable telephone is used as an independent unit in accordance with a key input from the user before the initiation of the call. In a second aspect of the invention, the telephone number of the remote party is stored in a memory during a call. When a connection or disconnection of a booster is detected, the call is terminated, and a redialing operation is automatically performed using the stored telephone number. In a third aspect of the invention, when the connection of a booster is detected during a call, an instruction is given to the booster to operate in a portable telephone mode. In a fourth aspect of the invention, when the connection or disconnection of a booster is detected during a call, a request to change the station class mark is sent to the base station.
