Abstract (en)
[origin: WO9927508A1] A pager (400) which provides voice paging protocol and a method (602) and apparatus for transmitting (906) and receiving (920) a selective call message that includes an indicator signal (610) indicative of at least one receiver and a data signal destined for the receiver. The method first transmits the indicator signal (722) and delays for a predetermined time interval. Subsequently, the method transmits (706) at least a portion of the first indicator signal and a message signal for the receiver (920) a first time. Thus, the present invention provides indicator signal time diversity before transmission of the actual message. The method may use an alert signal (e.g., a single bit) (100) indicative of a receiver as well as an address (202, 204) corresponding to the receiver.
