Abstract

A system and method for prioritizing a wireless communication to a portable communication device (102). In one example, a sensor (121) includes an electronic processor configured to capture an over-the-air identifier (404_1) of a portable communication device (102), determine a capture parameter based on at least one of a count of a number of times of capturing the over-the-air identifier and a last time of capturing the over-the-air identifier of the portable communication device (102), assign a priority level (414_1) to the portable communication device (102) based on the capture parameter, and prioritize the wireless communication between the sensor and the portable communication device (102) based on the priority level (414_1) assigned to the portable communication device (102).

Claims

1. A method for prioritizing a wireless communication to a portable communication device, the method comprising:

operating one or more sensors;

capturing, with the one or more sensors, an over-the-air identifier of the portable communication device;

determining, with an electronic processor, a capture parameter based on at least one of a count of a number of times of capturing the over-the-air identifier and a last time of capturing the over-the-air identifier of the portable communication device;

assigning, with the electronic processor, a priority level to the portable communication device based on the capture parameter; and

prioritizing, with the electronic processor, the wireless communication between the one or more sensors and the portable communication device based on the priority level assigned to the portable communication device.

2. The method of claim 1, wherein a frequency of queries sent from the one or more sensors to the portable communication device is based on the priority level, and wherein the queries are related to determining an evacuation status.

3. The method of claim 1, wherein a frequency of updates of an evacuation status sent from the portable communication device to the one or more sensors is based on the priority level.

4. The method of claim 1, wherein the priority level assigned to the portable communication device is based on a duration of communication between the portable communication device and the one or more sensors.

5. The method of claim 1, wherein a quality of service of the communication channel associate associated with the wireless communication is inversely proportional to the count of the number of times the over-the-air identifier of the portable communication device is received at the one or more sensors.

6. The method of claim 1, wherein capturing the over-the-air identifier includes capturing a media access control address.

7. The method of claim 1, wherein capturing the over-the-air identifier includes capturing an international mobile equipment identity number.

8. The method of claim 1, wherein operating one or more sensors includes operating one or more Bluetooth low energy beacons.

9. A sensor comprising:

an electronic processor configured to;

capture an over-the-air identifier of a portable communication device;

determine a capture parameter based on at least one of a count of a number of times of capture of the over-the-air identifier and a last time of capturing the over-the-air identifier of the portable communication device;

assign a priority level to the portable communication device based on the capture parameter; and

prioritize a wireless communication between the sensor and the portable communication device based on the priority level assigned to the portable communication device.

10. The sensor of claim 9, wherein the over-the-air identifier includes a media access control address.

11. The sensor of claim 9, wherein the over-the-air identifier includes an international mobile equipment identity number.

12. The sensor of claim 9, wherein the sensor comprises a wireless router.

13. The sensor of claim 9, wherein the sensor comprises a Bluetooth low energy beacon.

14. The sensor of claim 9, wherein the sensor comprises a long term evolution receiver.

15. The sensor of claim 9, wherein the electronic processor is communicatively coupled to a data storage configured to store the over-the-air identifier and the count of the number of times of capture of the over-the-air identifier.

16. A method of controlling a communication channel during a congestion period, the method comprising:

receiving, with a sensor, an over-the-air identifier of each of a plurality of portable communication devices;

determining, with an electronic processor, a capture parameter based on at least one of a count of a number of times the sensor receives the over-the-air identifier and a last time of capturing the over-the-air identifier of each of the plurality of portable communication devices; and

assigning, by the electronic processor, a quality of service for the communication channel based on the capture parameter.

17. The method of claim 16, further comprising:

prioritizing a wireless communication between the sensor and each of the plurality of portable communication devices based on a priority level associated with each of the portable communication devices, the priority level assigned based on the count of the number of times the sensor receives the over-the-air identifier of each of the plurality of portable communication devices.

18. The method of claim 16, further comprising:

sending an evacuation message to the plurality of portable communication devices based on at least the number of times the sensor receives the over-the-air identifier and the last time of capturing the over-the-air identifier of each of the plurality of portable communication devices.

19. The method of claim 18, wherein sending an evacuation message to the plurality of portable communication devices includes sending a broadcast evacuation message to each of the plurality of portable communication devices.

20. The method of claim 18, wherein sending an evacuation message to the plurality of portable communication devices includes sending an individually customized evacuation message to each of the plurality of portable communication devices.
