Abstract
Abstract The cellular mobile telephone apparatus comprises a radio unit (300) having an antenna (200), and a telephone unit (400) which is connected to the radio unit (300) via a line and is formed of a main unit (400a) and handset (400b). 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 the user that the call is originated is generated from a speaker (492) of the telephone unit (400a). 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.

Claim 4
Dependent Claim
27 words
The apparatus according to claim 1, characterized in that said second detection means comprises means for detecting an establishment of a speech channel in the radio channel.
Claim 5
Dependent Claim
27 words
The apparatus according to claim 1, characterized in that said second detection means comprises means for detecting an off-hook of the telecommunication apparatus of the other party.
Claim 6
Dependent Claim
47 words
The apparatus according to claim 1, further comprising: third detection means for detecting a termination of the call and a reason for the termination of the call; and second indicating means, connected to said third detection means, for indicating the reason for the termination of the call.
Claim 7
Dependent Claim
48 words
The apparatus according to claim 6, characterized in that said third detection means comprises means for detecting whether or not the user makes a termination operation, means for detecting whether or not the other party makes a termination operation, and means for detecting disconnection of the speech channel.
Claim 8
Dependent Claim
61 words
A radio telecommunication apparatus which is connected to a base station via a radio channel and communicated with a telecommunication apparatus of an other party via the base station, characterized by comprising: detection means for detecting a termination of communication and a reason for the termination; and indicating means, connected to said detection means, for indicating the reason for the termination.
Claim 9
Dependent Claim
49 words
The apparatus according to claim 8, characterized in that said detection means comprises means for characterized in that whether or not the user makes a termination operation, means for detecting whether or not the other party makes a termination operation, and means for detecting disconnection of the radio channel.
Claim 10
Dependent Claim
26 words
The apparatus according to claim 8, characterized in that said indicating means comprises means for generating a synthesized voice message expressing the reason for the termination.
Claim 11
Independent Claim
93 words
A method of originating a call from a ratio telecommunication apparatus which is connected to a base station via a radio channel, characterized by comprising the steps of: generating a call origination request with an identification number of a telecommunication apparatus of another party to be called; generating an indication tone upon the generation of the call origination request; seizing a control channel within the radio channel to detect a channel designation signal in the control channel; and seizing a speech channel within the radio channel in accordance with the channel designation signal.
Claim 12
Independent Claim
63 words
A method of terminating a call of a radio telecommunication apparatus which is connected to a base station via a radio channel, characterized by comprising the steps of: detecting whether the call is terminated due to the operation by the user of the telecommunication apparatus or due to the operation by another party; and generating a synthesized voice message denoting the detection result.
