Abstract

Aspects of the subject disclosure may include, for example, initiating emergency QoS measures in a RAN cell responsive to detecting an emergency condition applicable to the RAN cell, identifying, among a plurality of wireless communication devices served by the RAN cell, a set of non-emergency devices, identifying, among the set of non-emergency devices, one or more carrier aggregation (CA)-prone devices, and applying an updated buffer threshold value for a CA-prone device among the one or more CA-prone devices, to reduce a likelihood of initiation of carrier aggregation for the CA-prone device. Other embodiments are disclosed.

Claims (36)

1. A device, comprising:

a processing system for a radio access network (RAN) node, the processing system including a processor; and

a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:

identifying, among a set of communication devices communicating with the RAN node, one or more carrier aggregation (CA)-prone devices; and

applying an updated buffer threshold value for at least one CA-prone device among the one or more CA-prone devices, to reduce a likelihood of initiation of carrier aggregation for the at least one CA-prone device.

2. The device of claim 1 , wherein the identifying the one or more CA-prone devices comprises identifying the one or more CA-prone devices based on QoS class indices of the set of communication devices communicating with the RAN node.

3. The device of claim 1 , wherein the applying the updated buffer threshold is responsive to detecting an emergency condition applicable to the RAN node, and wherein the one or more CA-prone devices are identified as non-emergency devices.

4. The device of claim 1 , wherein the operations further comprise:

identifying a set of CA-capable devices from among the set of communication devices communicating with the RAN node; and

identifying the one or more CA-prone devices from among the set of CA-capable devices.

5. The device of claim 1 , wherein the operations further comprise selecting the updated buffer threshold value based on a type of traffic being conveyed to the at least one CA-prone device.

6. The device of claim 1 , wherein the operations further comprise selecting the updated buffer threshold value based on a burstiness associated with traffic being conveyed to the at least one CA-prone device.

7. The device of claim 1 , wherein the operations further comprise:

determining a respective buffer threshold time for each of the set of communication devices communicating with the RAN node; and

selecting the one or more CA-prone devices from among the set of communication devices communicating with the RAN node based on the respective buffer threshold time for the one or more CA-prone devices.

8. The device of claim 7 , wherein the operations further comprise determining the respective buffer threshold time for each of the set of communication devices communicating with the RAN node based on a respective data throughput estimate for each of the set of communication devices communicating with the RAN node.

9. The device of claim 8 , wherein the operations further comprise:

monitoring respective traffic patterns of each of the set of communication devices communicating with the RAN node to obtain traffic monitoring data; and

determining the respective data throughput estimate for each of the one or more CA-prone devices based on respective traffic monitoring data for each of the set of communication devices communicating with the RAN node, according to a queuing model.

10. The device of claim 7 , wherein the operations further comprise determining the respective buffer threshold time for each of the set of communication devices communicating with the RAN node based on a respective data throughput variability for each of the set of communication devices communicating with the RAN node.

11. The device of claim 1 , wherein the RAN node comprises a node of a next generation RAN (NG-RAN).

12. The device of claim 1 , wherein the RAN node comprises a next generation node B (gNB).

13. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processing system for a radio access network node, the processing system including a processor, facilitate performance of operations, the operations comprising:

identifying one or more carrier aggregation (CA)-prone devices among a plurality of wireless communication devices served by a Radio Access Network (RAN) node;

selecting an updated buffer threshold value for a CA-prone device among the one or more CA-prone devices based on a type of traffic being conveyed to the CA-prone device, a burstiness associated with traffic being conveyed to the CA-prone device, or a combination thereof; and

applying the updated buffer threshold value for the CA-prone device among the one or more CA-prone devices to reduce a likelihood of initiation of carrier aggregation for the CA-prone device.

14. The non-transitory machine-readable storage medium of claim 13 , wherein the operations further comprise identifying the one or more CA-prone devices based on QoS class indices of the plurality of wireless communication devices served by the RAN node.

15. The non-transitory machine-readable storage medium of claim 13 , wherein the applying the updated buffer threshold value is responsive to detecting an emergency condition applicable to the RAN node, and wherein the one or more CA-prone devices are identified as non-emergency devices.

16. The non-transitory machine-readable storage medium of claim 13 , wherein the operations further comprise selecting the updated buffer threshold value based on a burstiness associated with traffic being conveyed to the one or more CA-prone devices.

17. The non-transitory machine-readable storage medium of claim 13 , wherein the radio access network node comprises a next generation node B (gNB).

18. A method, comprising:

identifying, by a processing system including a processor, one or more carrier aggregation (CA)-prone devices among a plurality of wireless communication devices served by a Radio Access Network (RAN) node;

selecting, by the processing system, an updated buffer threshold value for a CA-prone device among the one or more CA-prone devices based on a type of traffic being conveyed to the CA-prone device, a burstiness associated with traffic being conveyed to the CA-prone device, or a combination thereof; and

applying the updated buffer threshold value for the CA-prone device among the one or more CA-prone devices to reduce a likelihood of initiation of carrier aggregation for the CA-prone device.

19. The method of claim 18 , wherein the applying the updated buffer threshold value is responsive to detecting an emergency condition applicable to the RAN node, and wherein the CA-prone device is identified as a non-emergency device.

20. The method of claim 18 , wherein the RAN node comprises a node of a next generation RAN (NG-RAN).
