In current trunked radio systems, subscriber units can be issued a busy status in response to a service request if there are not enough resources available to support their call. The subscriber can then notify the user that the request has been queued and a grant will be issued when sufftcient resources become available. The subscriber unit will continue to receive confirmation that the busy state still exists via periodic control channel updates. If an busy update is not received within a pre-defined time-out period, the subscriber unit will assume that its call has been missed or canceled and continue with normal operation.
