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, some IoT device may have multiple talkgroups assigned, and other talkgroups may have multiple IoT devices assigned. During operation, an action command is received over a first talkgroup and a first command type is issued to a first IoT device assigned to that talkgroup. A second action command is received over a second talkgroup and a second command type is issued to a second IoT device assigned to the second talkgroup. When determine that multiple radios are issuing action command to the same IoT device through PTT talkgroup, create a new PTT talkgroup to be populated with the multiple radios.

Claims

1. An apparatus comprising:

logic circuitry configured to receive a first Push-to-talk (PTT) talkgroup identification and map the first PTT talkgroup identification to an Internet-of-Things (IoT) device having a particular address, the logic circuitry also configured to determine a control command based on the IoT device, receive an identification of a radio attempting to operate the IoT device, determine that more-than-one radios are attempting to operate the IoT device, and cause the more-than-one radios to be added to a second PTT talkgroup; and

a network interface coupled to the logic circuitry, the network interface configured to output the control command to the particular address in order to operate the IoT device.

2. The apparatus of claim 1 wherein the second PTT talkgroup comprises a newly-created talkgroup.

3. The apparatus of claim 1 wherein the logic circuitry also receives a verbal action command and determines the control command based on both the IoT device and the verbal action command.

4. The apparatus of claim 3 further comprising a Natural-Language Processor (NLP) outputting the verbal action command to the logic circuitry.

5. The apparatus of claim 1 wherein the logic circuitry determines that the multiple users of the IoT device are performing opposite actions on the IoT device, and only cause the more-than-one radios to be added to a second PTT talkgroup when the users are performing opposite actions on the IoT device.

6. The apparatus of claim 1 further comprising:

a Wide-Area-Network (WAN) transceiver receiving transmissions over the first PTT talkgroup and the identification of the radio, and outputting the first PTT talkgroup and the radio identification to the logic circuitry.

7. The apparatus of claim 1 further comprising a database comprising the mapping of the first PTT talkgroup to the IoT device.

8. The apparatus of claim 1 wherein the first PTT talkgroup identification was received from an over-the-air, push-to-talk communication.

9. A method comprising the steps of:

receiving a first Push-to-Talk (PTT) talkgroup identification from multiple over-the-air transmissions of multiple radios attempting to control an Internet-of-Things (IoT) device;

determining that more than one of the multiple radios are communicating over one or more talkgroups assigned to a same IoT device; and

adding the radios communicating over the one or more talkgroups assigned to the same IoT device to a single second PTT talkgroup.

10. The method of claim 9 wherein the step of adding the radios to the single second talkgroup comprises the step of creating the single second talkgroup and adding the radios to the newly-created second talkgroup.

11. The method of claim 9 further comprising the steps of:

mapping the first PTT talkgroup identification to an Internet-of-Things (IoT) device having a particular address;

determining a control command based on the IoT device; and

outputting the control command to the particular address to operate the IoT device.

12. The method of claim 9 wherein the PTT talkgroup identification was received from a push-to-talk transmission from the radio.

13. A method comprising the steps of:

receiving a first Push-to-Talk (PTT) talkgroup identification from a first over-the-air transmission of a first radio, wherein the talkgroup identification comprises an identification of a first talkgroup used to control an Internet-of-Things (IoT) device;

receiving the first PTT talkgroup identification from a second over-the-air transmission of a second radio; and

causing a second talkgroup to be populated with the first and the second radio only when the talkgroup identification received from the first and the second radio are identical.

14. The method of claim 13 wherein the second talkgroup comprises a newly-created talkgroup.

15. The method of claim 13 further comprising the steps of:

mapping the first PTT talkgroup identification to a first Internet-of-Things (IoT) device having a first address;

determining a control command based on the first IoT device; and

outputting the control command to the first IoT device at the first address.
