Abstract
A method and apparatus for providing extended battery saving operation in a conventional selective call signaling protocol, such as the POCSAG signaling protocol includes the transmission of an ordered batch identifier code word in the first frame following a preamble transmission. Upon detection of the ordered batch identifier code word, those selective call receivers capable of extended battery saving operation would supply power to the receiver only during those batches assigned to the receiver group to which the selective call receiver belongs, such as for every second or fourth batch transmission. The method for providing extended battery saving capability is transparent to conventional selective call receivers operating within the system.
