Abstract
A method is provided for signalling wherein one or more of a group of selective call receivers periodically synchronize to a portion of a received signal and determine whether an indicator indicating the presence of information for any of the group of selective call receivers reside within the received signal. If so, the selective call receivers determine whether other portions of the received signal contain information designated for them. Otherwise, if the indicator is not present, the selective call receivers conserve an energy source.
