Abstract
A user's device will periodically send short PTT bursts to an application talkgroup and wait for an acknowledgement (ACK). The acknowledgement will allow the software application to execute the application as part of the site license. If the site license is used up (i.e., a maximum number of simultaneous users has been reached), then a negative acknowledgment (NACK) will be sent to the device, and the software will deny the user access to the software.
