  • Method and apparatus for improving audio reception in a paging device
    Patent number: 9270307
    Abstract: A method (300) and apparatus (200) are provided for operating a portable pager. The method and apparatus eliminate channel noise between paging tones and voice messages. Channel noise is squelched between paging tones and voice messages using a delayed N timer, thereby allowing the speaker to remain on. Paging tones are received and played at the speaker during a signaling squelch mode of operation. The detection of the paging tones and subsequent drop in carrier signal, initiates a timer during which channel noise is squelched during a carrier squelch mode of operation. The timer is delayed (delay N timer) so as to expire only after the carrier frequency is re-established. Once the carrier signal is re-established followed by the delayed timer expiration, the carrier squelch is removed. The speaker remains on during both signaling squelch and carrier squelch. Hence, paging tones are heard, channel noise is silenced, and then voice messages are played.
