Abstract
A selective paging receiver with message display has a receiver section, a number setting circuit, a paging number detector, and a display panel. The receiver section receives paging signals sent to the paging receiver, and recovers a paging number data signal and a message data signal from the paging signals. The message data signal includes both individual message data for the paging receiver, and common message data for the paging receiver in common with a preselected group of similar receivers. A number setting circuit assigns both a preselected individual paging number and a preselected common paging number to the receiver. The paging number detector searches for the individual paging number in a particular group time frame of the paging number signal. This time frame corresponds to a paging receiver group to which the paging receiver belongs. The paging number detector conducts a parallel search for the common paging number without regard for the particular group time frame. Upon detection of the individual paging number, the paging number detector outputs an individual detection signal. Upon detection of the common paging number, the paging number detector outputs a common detection signal. The display responds to the individual detection signal by displaying the contents of the individual message data and responds to the common detection signal by displaying the contents of the common message data.
