发明名称 Method and control apparatus for radio paging systems
摘要 A control apparatus for an automatic radio paging system comprising a paging tone encoder circuit for generating a plurality of paging signals, a radio transmitter for transmitting the paging signals and a plurality of mobile pagers which are each tuned to a different paging signal. In particular, the control apparatus of the present invention communicatively coupled a Touch-Tone telephone subset with a radio paging system such that the person making the page is capable of initiating and controlling the paging operation from a remote telephone subset. The control apparatus provides the calling party with access to the radio paging system only after the calling party submits a properly coded access signal to the control apparatus. Thereafter, the calling party is free to initiate a page by sending paging information to the control apparatus from a Touch-Tone telephone subset. In response to this paging information, the control apparatus generates and transmits a paging signal corresponding to the mobile pager of the party being paged. Following transmission of the paging signal, the control apparatus couples the calling subset with the radio transmitter so that the calling party can transmit a voice communication to the paged party. The control apparatus is designed for use with a local or remote transmitter.
