A method and apparatus for providing fair access in a group communication system. Permission to transmit is based on a variable-level priority scheme. The variable priority level of each member in the system is based upon the number of event occurrences that have occurred in the past. In a first embodiment, the number of event occurrences is defined as the number of times that a member has been denied permission to transmit. The more denials that a member accumulates, the higher an corresponding priority level becomes. In a second embodiment, the priority level is based on the amount of time which has elapsed from when a net member was last granted the transmission privilege. The greater the time differential between when a member has last been granted the transmission privilege and a present access request, the greater the variable priority level becomes. |
