Abstract
Battery saving can be achieved in a selective call receiver (i.e. in a radio pager) by only periodically activating the receiver. The activation rate or time cycle of the receiver determines how often the receiver can receive messages and the amount of time between the periods when messages can be received. The present invention provides a selective call receiver which has variable cycle rates. A system includes a plurality of receivers, some of which have a first cycle rate and some of which have a second cycle rate.
