WIRELESS MESSAGING SYSTEM FOR USING ESTIMATED DELIVERY PARAMETER REQUIREMENTS FOR MEETING TARGET TRANSMISSION RELIABILITY

摘要

A controller (112) monitors (306) delivery of two-way outbound messages to a plurality of portable messaging units (122), and records (308) reliability statistics (238) for the two-way outbound messages as a function of delivery parameters. The controller also determines (316) a target transmission reliability for sending a message; and estimates (318), from the reliability statistics, the required delivery parameters for sending the message at the target transmission reliability. The controller then transmits (320) the message in accordance with the required delivery parameters.
