  • System and method for managing affiliation requests in a communication system
    Patent number: 8000731
    Abstract: A system and method for managing call affiliation in a communication system having a plurality of communication units. When a public call announcement is initiated, a broadcast data message is transmitted to the communication units identifying a public announcement talkgroup for the call. Upon receiving the broadcast data message, each of the communication units waits a random amount of time before attempting to affiliate to the public announcement talkgroup. At the same time, each communication unit also monitors other messages on the control channel. Each communication unit joins the public announcement talkgroup upon the first of either (1) receiving an affiliation grant in response to an affiliation request transmitted by the communication unit, or (2) detecting an affiliation grant being transmitted to a different communication unit attempting to affiliate to the same talkgroup.
