Reset of dynamic allowed area list for a UE

1. A method for reset of a dynamic allowed area (DAA) list for a user equipment (UE), the method comprising:

receiving, at a network node, a control plane message indicating a request for a reset of the DAA list;

in response to receiving the control plane message indicating a request for a reset of the DAA list, the network node determining whether to maintain the DAA list or reset the DAA list; and

the network node, based on the determination, maintaining or resetting the DAA list.

2. The method of claim 1 , wherein

the network node is an Access and Mobility Management Function (AMF), a Policy Control Function (PCF), or a combination of an AMF and a PCF, and

the control plane message is a deregistration request or a reset request.

3. The method of claim 1 , wherein determining whether to maintain the DAA list or reset the DAA list comprises:

determining whether a number of attempts by the UE to reset the DAA list has reached a threshold;

determining a subscription type and a frequency of attempts by the UE to reset the DAA list; or

determining a number of attempts by the UE to reset the DAA list in one or more geographical locations.

4. The method of claim 1 , wherein

the network node determines to maintain the DAA list, and

the method further comprise determining a quarantine time, the quarantine time identifying a time period during which a reset of the DAA list will not be accepted.

5. The method of claim 4 , further comprising:

after receiving the first control plane message, receiving a second control plane message, the second control plane message indicating a request for a reset of the DAA list;

in response to receiving the second control plane message, determining whether the time period identified by the determined quarantine time has expired; and

as a result of determining that the time period has not expired, refraining from resetting the DAA list.

6. The method of claim 5 , further comprising:

after refraining from resetting the DAA list, determining that the time period has expired; and

as a result of determining that the time period as expired:

resetting the DAA list, and

transmitting a second response message, the second response message comprising information indicating that the DAA list has been reset.

7. The method of claim 1 , wherein the DAA list is a set of allowed areas, AAs, or Tracking Areas, TAs, a list of node IDs, or a list of cell IDs, that automatically change over time.

8. The method of claim 1 , wherein a granularity of the DAA list is one or more of TA, RAN node area, or cell level.

9. The method of claim 1 , wherein the step of determining whether to maintain the DAA list or reset the DAA list comprises:

determining whether a number of attempts by the UE to reset the DAA list has reached a threshold, or

determining whether or not, at the time the control plane message was received, a quarantine time had expired, the quarantine time being a time period during which a reset of the DAA list will not be accepted.

10. The method of claim 1 , wherein

the DAA list comprises a plurality of entries, and

the network node, based on the determination, resets the DAA list by removing the plurality of entries from the list.

11. A control node the control node comprising:

a transmitter;

a receiver;

a memory; and

processing circuitry, wherein the control node is configured to perform the method of claim 1 .

12. A computer program product comprising a non-transitory computer readable medium storing instructions for performing the method of claim 1 .

13. A method performed by a user equipment (UE) for reset of a dynamic allowed area (DAA) list for the UE, the method comprising:

obtaining an indication that a DAA threshold has been reached;

in response to obtaining the indication, transmitting a first message to a network node, the first message indicating a request for a reset of the DAA list; and

receiving a second message transmitted by the network node, the second message comprising information indicating whether or not the DAA list has been reset.

14. The method of claim 13 , wherein the second message comprises information indicating a time period during which the DAA list for the UE will not be reset in response to a rest indication transmitted by the UE.

15. The method of claim 14 , further comprising the UE determining that the time period has not expired and, as a result of determining that the time period has not expired, the UE refraining from requesting a reset of the DAA list until after the time period has elapsed.

16. The method of claim 15 , further comprising:

transmitting, at a time subsequent to the expiration of the time period, a third message, the third message indicating a request for a reset of the DAA list; and

receiving a fourth message responsive to the third message, the fourth message comprising information indicating whether or not the DAA list has been reset.

17. The method of claim 13 , wherein the second message further comprises the DAA list.

18. The method of claim 13 , wherein the network node is an Access and Mobility Management Function (AMF), a Policy Control Function (PCF), or a combination of an AMF and a PCF.

19. The method of claim 13 , wherein the DAA list is a set of allowed areas, AAs, or Tracking Areas, TAs, a list of node IDs, or a list of cell IDs, that automatically change over time.

20. The method of claim 13 , wherein a granularity of the DAA list is one or more of TA, RAN node area, or cell level.

21. A UE, the UE comprising:

a transmitter;

a receiver;

a memory; and

processing circuitry, wherein the UE is configured to perform the method of claim 13 .

22. A computer program product comprising a non-transitory computer readable medium storing instructions for performing the method of claim 13 .
