Abstract
The cellular mobile telephone apparatus comprises a radio unit having an antenna, and a telephone unit which is connected to the radio unit via a line and is formed of a main unit and handset. To originate a call, a user dials the telephone number of an other party to be called. When the dialing is detected, a calling tone indicating to the user that the call being originated is generated from a speaker of the telephone unit. To start speech communication, it is necessary to designate and capture a speech channel in the radio channel. When the capture of the designated speech channel is detected, the calling tone is stopped. After the communication, there are three types of terminating the call. At the end of communication, the type of the termination is detected and the corresponding synthesized voice message is generated.
