Abstract

A paging system where messages are numbered before they are transmitted. The paging receivers in the system compare both the number and the text information in each message which is received to the message number and the text information in the most recently received previous message. The comparison is used to determine if the same message was previously received and if the any messages were missed. The receiver includes an icon which is turned on to indicate if a message has been received. The icon is set to a blinking state if a message is received and if there is a break is the sequence of message numbers indicating that a message has been missed.
