ABSTRACT:
A method and apparatus for entering a net within a group communication network provides for requesting a current list of available nets that the communication device may join from a controller and, after receiving the current list of available nets from the controller, selecting a net from the current list of available nets. The method and apparatus further allows the communication device to send a request to the controller for joining the selected net, which may be followed by receiving a response from the controller that the communication device has been added to the list of current participants in the selected net. In another aspect of the invention, a method and apparatus for exiting a net within a group communication network provides for sending a request to the controller for exiting the net, receiving a response from the controller that the communication device has been removed from the list of current participants in the net, and exiting the net.
