The present invention is a novel and improved method for providing broadcast short message services (SMS) in a communication network. It is an objective of the present invention to provide a method and apparatus that insures the successful transmission of the broadcast message while minimizing the impact of providing the short messaging service on overall system capacity. It is further the objective of the present invention to provide a method and apparatus for receiving broadcast messages without depriving the receiver of the benefits of slotted paging, that being the savings in power consumption.
