A new generation of two-way paging devices will allow the subscriber unit to communicate with the paging system and indicate to the system various error conditions. One such error condition can occur when the paging system sends a series of messages to the subscriber unit with the acknowledgment to be transmitted by the subscriber unit sometime in the future. The risk involved is that the subscriber unit may miss one of the messages in the series. In the current scheme of things the subscriber unit is not aware that it has missed an entire message. Only when the paging system fails to receive an acknowl- edgment for the missed message will the system real- ize that a retransmission is in order. The paging system would have to wait for all the acknowledg- ments to arrive and then determine not only that a message was missed but also which message was missed. This determination would be based on the fact that the number of responses is less than the total number ofmessages transmitted to the pager.
