A method of determining when a communication device (11) is out-of-range of an incoming call from a central station (25), disallows communication between them for the out-of-range condition. In the central station (25), a page signal is transmitted (20) representing a call to the communication device (11). The central station (25) is capable of receiving (12) signals transmitted by the communication device (11). Recognizing (40) a lack of response by the communication device to the page signal from the central station, the central station withholds the transmission of a call set-up grant signal. Meanwhile, in the communication device, signals transmitted by the central station are received (50). The communication device transmits a page-response signal (555) representing the reception of the page signal. Recognizing an absence of a call set-up grant signal (562), the communication device indicates (563) to the subscriber that the communication device is out-of-range of the coverage area of the central station for the call.

대표청구항 ▼

A cordless telephone comprising: means for receiving a page signal providing notification that an incoming call is intended for the cordless telephone; means for transmitting a page-response signal acknowledging the reception of the page signal; means for detecting a call set-up grant signal responsive to the page-response signal to complete a call set-up; means for enabling the detecting means for a predetermined signal sampling time during which reception of the call set-up grant signal is expected, in response to the page-response signal transmitted; means for determining that the cordless telephone is out-of-range when the call set-up grant signal is not detected by the detecting means during the predetermined signal sampling time; and means for indicating to a user that notification of an incoming call was received and that the cordless telephone is out-of-range thereby preventing completion of the call set-up.
