Abstract: A method and apparatus for PTT over IoT is described herein. During operation, each IoT device will be assigned to a talkgroup. Some talkgroups may have a single IoT device assigned, and other talkgroups may have multiple IoT devices assigned. During operation, a control command is received over a first talkgroup that is used to control a first IoT device assigned to that talkgroup. Prior to executing the control command, a set of secondary IoT devices will be determined based on a task assigned to the officer. The secondary IoT devices will be accessed to determine their statuses. The status of the secondary IoT devices will be used as a trigger as to whether or not to allow the control command to be sent to the first IoT device.
