Abstract
Abstract When the user of a radio telecommunication apparatus requests a privacy mode and a call origination, the apparatus of the present invention sends a call signal including the requested privacy mode to a base station. Thereafter, the apparatus receives an acknowledge signal from the base station, including a designated communication mode designated by the base station. If the received designated communication mode does not correspond to the requested privacy mode, the apparatus warns the user.

A radio telecommunication apparatus used in a radio telecommunication system, wherein speech signals are selectively communicated with a base station in either one of a privacy mode or a communication mode other than the privacy mode characterized in that the radio telecommunication apparatus comprises: requesting means (3) for requesting the base station to designate the privacy mode; receiving means (21) for receiving a designated communication mode designated by the base station; and warning means (5, 76, 78) responsive to the requesting means (3) and the receiving means (21) for warning the user of the apparatus if the received designated communication mode does not correspond to the requested privacy mode.
Claim 2
Dependent Claim
55 words
The apparatus of claim 1 characterized in that the requesting means (3, 15) comprises input means (3) for inputting a call origination request and a privacy mode request, and sending means (15) responsive to the input means (3) for sending a call signal including the inputted call origination request and the inputted privacy mode request.
Claim 3
Dependent Claim
40 words
The apparatus of claim 1 or 2 characterized in that the radio telecommunication apparatus further comprises mode assigning means (30) responsive to the receiving means (21) for assigning the received designated communication mode to a communication mode of the apparatus.
Claim 4
Independent Claim
24 words
The apparatus claimed in any preceding claim characterized in that the warning means (5, 76, 78) comprises sound generating means (78) for generating sound.
Claim 5
Independent Claim
40 words
The apparatus claimed in any preceding claim characterized in that the warning means (5, 76, 78) comprises informing means (5, 76) for informing the user of the apparatus that the requested privacy mode is not designated by the base station.
Claim 6
Dependent Claim
33 words
The apparatus of claim 5 characterized in that the informing means (5, 76) comprises displaying means (5) for displaying information indicating that the requested privacy mode is not designated by the base station.
Claim 7
Dependent Claim
36 words
The apparatus of claim 5 characterized in that the informing means (5, 76) comprises voice synthesis means (76) for generating a synthesized voice indicating that the requested privacy mode is not designated by the base station.
Claim 8
Dependent Claim
112 words
A radio telecommunication apparatus used in a radio telecommunication system, wherein speech signals are selectively communicated with a base station in either one of a privacy mode or a communication mode other than the privacy mode characterized in that the radio telecommunication apparatus comprises: receiving means (21) for receiving a mode change indication signal including a designated communication mode from the base station while the speech signals are communicated with the base station in the privacy mode; and warning means (5, 76, 78) responsive to the receiving means (21) for warning the user of the apparatus if the received designated communication mode does not correspond to the privacy mode of the apparatus.
Claim 9
Dependent Claim
53 words
The apparatus of claim 8 characterized in that the radio telecommunication apparatus further comprises mode change means (30) responsive to the receiving means for changing the privacy mode of the apparatus to the received designated communication mode if the received designated communication mode does not correspond to the privacy mode of the apparatus.

Claim 14
Dependent Claim
157 words
A radio telecommunication apparatus used in a radio telecommunication system, wherein speech signals are selectively communicated with a first base station covering a first zone in either one of a privacy mode or a communication mode other than the privacy mode, and wherein the first base station sends a mode change indication signal including a communication mode of a second base station if the apparatus approaches a second zone covered by the second base station characterized in that the radio telecommunication apparatus comprises: receiving means (21) for receiving the mode change indication signal including the communication mode of the second base station while the speech signals are communicated with the first base station in the privacy mode; and warning means (5, 76, 78) responsive to the receiving means (21) for warning the user of the apparatus if the received sent communication mode of the second base station does not correspond to the privacy mode of the apparatus.
Claim 15
Independent Claim
89 words
A method of warning the user of a radio telecommunication apparatus used in a radio telecommunication system, wherein speech signals are selectively communicated with a base station in either one of a privacy mode or a communication mode other than the privacy mode characterized in that the method comprises the steps of: requesting the base station to designate the privacy mode; receiving a designated communication mode designated by the base station; and warning the user if the received designated communication mode does not correspond to the requested privacy mode.
Claim 16
Independent Claim
101 words
A method of warning the user of a radio telecommunication apparatus used in a radio telecommunication system, wherein speech signals are selectively communicated with a base station in either one of a privacy mode or a communication mode other than the privacy mode characterized in that the method comprises the steps of: receiving a mode change indication signal including a designated communication mode from the base station while the speech signals are communicated with the base station in the privacy mode; and warning the user if the received designated communication mode does not correspond to the privacy mode of the apparatus.
Claim 17
Independent Claim
146 words
A method of warning the user of a radio telecommunication apparatus used in a radio telecommunication system, wherein speech signals are selectively communicated with a first base station covering a first zone in either one of a privacy mode or a communication mode other than the privacy mode, and wherein the first base station sends a mode change indication signal including a communication mode of a second base station if the apparatus approaches a second zone covered by the second base station characterized in that the method comprises the steps of: receiving the mode change indication signal including the communication mode of the second base station while the speech signals are communicated with the first base station in the privacy mode; and warning the user if the received sent communication mode of the second base station does not correspond to the privacy mode of the apparatus.
