Abstract

See full text

A repeater receives a first group message directed to a talk group. The repeater assigns a first unique message identifier including a generated first sequence number to the first group message. The repeater broadcasts the first group message with the first unique message identifier and the unique talk group address to the talk group. The repeater later receives a second group message directed to the talk group, generates a second sequence number from the generated first sequence number, assigns a second unique message identifier including the second sequence number to the second group message and broadcasts the second group message to the talk group. The first sequence number and the second sequence number may be used by a receiving radio of the talk group to determine if the radio failed to receive one or more group messages or if a received group messages is a duplicate message.
