Abstract
A paging system transmits consecutively numbered page messages to receivers. Receivers detect missing page messages by interrogation of received page message numbers, and a missing page message is indicated by a gap in received page message numbers. However, page messages may be separated by long time intervals and a gap in received message numbers can not be detected until a subsequent page message is received. To more immediately detect a missing page message, a sequence message generated by the paging system provides a last transmitted page message number to receivers during otherwise unused portions of the transmission bandwidth. The receivers can thereby detect missing page messages without waiting until receiving a subsequent page message and without depleting the transmission bandwidth resource.
