ABSTRACT:
A selective call receiver (130) for conserving power having a first battery saving period, has a receiver (504) for receiving and obtaining synchronization to selective call signals having a multiplicity of frames. A synchronizer (602, 604) determines a first occurrence of a preassigned frame (200) of the multiplicity of frames. The receiver (504) receives the preassigned frame (200), each of frame designating a system collapse value for selecting a second battery saving period, and a TD collapse bit (406) and a TD collapse value (408) for designating a third battery saving period. A decoder/controller (506) decodes the TD collapse bit (406), the TD collapse value (408) and the system collapse value transmitted in the selective call signals. The decoder/controller (506) calculates the third battery saving period from the TD collapse value (408) and a battery save selector (616) selects the third battery saving period designated by the TD collapse value (408) when the TD collapse bit (406) is set.
