Abstract

In response to a determination that network communication traffic at a network node relates to an emergency communication, a network controller can be operable to analyze a network condition associated with the network node. Based on an analysis of the network condition, the network controller can facilitate an adjustment to a partition of an integrated access and backhaul link. The network controller can further be operative to determine whether an operator policy is applicable to the adjustment of the partition. Additionally, the network controller can be operable to facilitate the selection of a path to route the emergency communication based upon the network condition and the operator policy.

Claims

1. A device, comprising:

a processor; and

a memory that stores computer executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

in response to a determination that network communication traffic at a first network node device relates to an emergency responder communication, analyzing a network condition associated with the first network node device; and

based on a result of the analyzing of the network condition, facilitating an adjustment to a partition of an integrated access and backhaul link, wherein;

the integrated access and backhaul link comprises an access communication link integrated with a backhaul communication link,

the access communication link carries a first transmission between the first network node device and a user equipment,

the backhaul communication link carries a second transmission between the first network node device and a second network node device, and

the partition relates to a first bandwidth relating to the access communication link and a second bandwidth relating to the backhaul communication link.

2. The device of claim 1, wherein the first transmission and the second transmission are multiplexed on the integrated access and backhaul link.

3. The device of claim 1, wherein the first network node device comprises a transmit and receive point device for transmission and reception of packets of information.

4. The device of claim 1, wherein the first network node device comprises a distributed unit device.

5. The device of claim 1, wherein the determination comprises determining whether a data frame contains an indicator indicating a presence of the emergency responder communication.

6. The device of claim 1, wherein facilitating the adjustment comprises facilitating changing an amount of the first bandwidth.

7. The device of claim 1, wherein facilitating the adjustment comprises facilitating changing an amount of the second bandwidth.

8. The device of claim 1, wherein facilitating the adjustment comprises facilitating a change in a frequency of transmission of time slots allocated for transmissions on the access communication link.

9. The device of claim 1, wherein facilitating the adjustment comprises facilitating a change in a frequency of transmission of time slots allocated for transmissions on the backhaul communication link.

10. A method, comprising:

receiving, by a network controller device comprising a processor, data from a first network node device, wherein the data comprises;

an indicator that network communication traffic at the first network node device comprises an emergency communication, and

information related to a network condition associated with the first network node device; and

based on a presence of the indicator and the network condition, facilitating, by the network controller device, managing a partition of an integrated access and backhaul link, wherein;

the integrated access and backhaul link comprises an access communication link integrated with a backhaul communication link,

the access communication link carries a first transmission between the first network node device and a user equipment,

the backhaul communication link carries a second transmission between the first network node device and a second network node device, and

the partition relates to a first amount of bandwidth related to the access communication link and a second amount of bandwidth related to the backhaul communication link.

11. The method of claim 10, wherein facilitating the managing of the integrated access and backhaul link comprises facilitating re-routing a communication packet of the emergency communication from a first communication link to a second communication link of the integrated access and backhaul link, based on the network condition.

12. The method of claim 11, wherein the first communication link comprises the access communication link.

13. The method of claim 11, wherein the second communication link comprises the backhaul communication link.

14. The method of claim 10, wherein the network condition comprises a first link condition associated with the access communication link and a second link condition associated with the backhaul communication link.

15. The method of claim 10, further comprising, determining, by the network controller device, a path to route the emergency communication.

16. The method of claim 15, wherein the determining the path is based on a number of intervening network node devices between the first network node device and a destination device.

17. A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

in response to receiving data indicative of emergency communication traffic present at a network node device, analyzing information related to a network condition associated with the network node device;

determining, based on the analyzing, an adjustment of a partition of an integrated access and backhaul link that carries network traffic, wherein;

the integrated access and backhaul link comprises an access communication link integrated with a backhaul communication link,

the access communication link carries a first transmission between the network node device and a user equipment,

the backhaul communication link carries a second transmission between the network node device and a different network node device, and

the partition relates to a first amount of bandwidth related to the access communication link and a second amount of bandwidth related to the backhaul communication link; and

managing the partition based on the adjustment.

18. The machine-readable storage medium of claim 17, wherein the operations further comprise determining whether an operator policy is applicable to the adjustment of the partition.

19. The machine-readable storage medium of claim 18, wherein the operations further comprise selecting a path to route the emergency communication, and wherein selecting the path considers a number of intervening network node devices between the network node device and a destination device.

20. The machine-readable storage medium of claim 19, wherein the selecting the path is based on the network condition and the operator policy.
