Abstract: A method and apparatus for on-the-fly mode change in a paging system (201) is provided. A transmitter controller (301) in a base station (207) receives paging information. From the paging information, the transmitter controller (301) is capable of identifying a plurality of paging protocols associated with the paging information. Each identified paging protocol is associated with a corresponding mode. Mode information (D.sub.3, D.sub.4) corresponding to each mode is provided to an exciter (303). Based upon the mode information, the exciter (303) modulates a frequency using predetermined values of frequency deviation and frequency offset associated with the mode. The exciter (303) produces a modulated signal that transitions from one mode to another without delay.
