MESSAGE/RESPONSE TRACKING FOR A TWO-WAY PAGER

摘要

A two-way selective call receiving device (10) is responsive to the receipt of a message with an identifier falling within a limited set of possible identifiers in order to control the ability of the selective call receiving device (10) to transmit a response to a prior message having the same identifier. The selective call receiving device (10) utilizes a tracking table (54) that stores information tracking received message with their associated identifiers. A controller (18) determines whether a prior message having the same identifier as a newly received message is stored in the device (10) and for which a response has not already been transmitted. If so, the controller (18) prevents a response to the prior message from thereafter being transmitted.
