Abstract
A radio telephone apparatus comprises detecting means for detecting a predetermined signal sequence other than a signal sequence associated with address signaling or an incoming call indicator signal and means for indicating that a call is received in response to the detection of the predetermined signal sequence. A user of the apparatus may prestore identification numbers of parties from whom the user wishes to receive calls. Also, by means of a transmitted password and a comparison of the password upon receipt with a prestored password, incoming calls will be received.

25. Radio telephone apparatus comprising:
-
receiving means for receiving signals over one or more radio channels; first establishing means for establishing a first communication link with a base station in response to first channel establishment information included in the signals received by said receiving means; first detecting means for detecting a signal sequence, indicative of an incoming call to the radio telephone apparatus, in the signals received through said first communication link; second establishing means for establishing a second communication link with an apparatus calling the radio telephone apparatus on the basis of second channel establishment information included in the signals received by said receiving means instead of releasing said first communication link in response to the detection of said signal sequence; second detecting means for detecting one or more password signals received through said second communication link; and indicating means for indicating reception of a call in response to the detection of said password signals. - View Dependent Claims (26, 27)
