A fixed portion (102) of a two-way messaging system transmits (502) a first message (400) including a value (408) indicative of a response probability desired from a portable subscriber unit (122). The portable subscriber unit receives (602) the first message and selects (614) between responding (616) and not responding to the first message, in a manner that satisfies the response probability.

Method and apparatus for reducing inbound transmissions in a two-way

A selective call device (130) has a receiver (204) for receiving information at a first rate and a switch (229, 230) for selecting a streaming mode for providing the information. A processor (210) for determining when the streaming mode is selected, and in response thereto, creates a buffer (221, 222) for retaining the information. The processor (210) transfers the information from the buffer (221, 222) at a second rate for a display (228) to present the information that is transferred from the buffer (221, 222) as a continuous stream.

A method and apparatus eliminates an audible noise burst after reestablishment of an external timing signal in a radio base station (102). After a loss of the external timing signal, the base station (102) temporarily operates from an internal timing signal generator (226) to provide digital communications over a radio link (106) with a portable communication unit (120). After reestablishment of the external timing signal, the base station (102) detects (304) the presence of the signal, waits (306) for the signal to stabilize, and controls (312) the portable communication unit (120) to disable audio while switching (316) back to the external timing signal.

A method and apparatus are provided for synchronizing over-the-air time division duplexing communication within a defined geographical coverage area (201) of a communication system (200) that provides at least cordless radiotelephone operation between a plurality of portable radiotelephone transceivers and a plurality of telepoint base stations (202, 204, 206) geographically located within the coverage area (201). The communication system (200) transmits over-the-air a synchronization timing signal (203) including timing information corresponding to a transmit-and-receive duty cycle timing for time division duplexing communication. At least one telepoint base station (204, 206) within the coverage area (201) receives the synchronization timing signal (203). The at least one telepoint base station (204, 206) synchronizes its over-the-air time division duplexing communication transmit-and-receive duty cycle timing to the timing information.
