To provide a system and method for performing queued and moderated talk groups, in a system featuring network-provided half-duplex communications talk group sessions.

For queuing, rather than dropping a talk request from a user which is listening, the request is forwarded to a network and maintained in a list which is used to grant access to a talk channel. For moderated talk groups, a wireless device is designated to be a moderator network device. The requests for the talk channel are then forwarded to the moderator network device. The moderator network device is equipped with functionality allowing a user of the device to select the order in which devices are granted the talk channel. In other implementations, meta-groups are provided, and rules of order for talk group sessions are implemented.
