Method and apparatus for managing service area for UE in wireless communication system

1 . A method performed by an access and mobility management function (AMF) in a wireless communication system, the method comprising:

receiving, from an uncrewed aerial system (UAS) service supplier (USS), via a network exposer function (NEF), a first message including first information on a planned flight route for a user equipment (UE) configured for at least one UAS service;

identifying whether the UE is flying in the planned flight route; and

transmitting, to the USS, via the NEF, a notification message including second information on whether the UE is flying in the planned flight route in response to the identification,

wherein the first message further includes third information indicating a request for a report for the second information on whether the UE is flying in the planned flight route, and

wherein the first information on the planned flight route is related to a list of cells or a list of radio access node (RAN) node identifiers.

2 . The method of claim 1 , wherein the second information indicates whether the UE moves out of the area related to the panned flight route.

3 . The method of claim 1 , wherein the notification message further includes location information of the UE.

4 . The method of claim 1 , further comprising:

determining at least one candidate base station to be used by the UE, based on flight-related information for the UE received from the USS via the NEF;

transmitting, to the at least one candidate base station, a request message for requesting aviation communication-related information for the at least one candidate base station;

receiving, from the at least one candidate base station, a response message including the aviation communication-related information for the at least one candidate base station; and

generating a handover list to be used by the UE, based on the flight-related information on the UE and the aviation communication-related information about the at least one candidate base station.

5 . The method of claim 4 , further comprising:

transmitting, to the at least one candidate base station, the handover list; and

transmitting, to the UE, the handover list.

6 . The method of claim 4 , wherein the flight-related information on the UE further includes at least one of:

location information on a flight departure point,

location information on a flight arrival point,

an estimated aviation communication start time,

an estimated aviation communication end time,

an estimated flight route,

an estimated flight altitude,

an estimated flight speed,

location information on a major pass point, or

an estimated time of a pass over the major pass point.

7 . A method performed by an uncrewed aerial system (UAS) service supplier (USS) in a wireless communication system, the method comprising:

transmitting, to an access and mobility management function (AMF), via a network exposer function (NEF), a first message including first information on a planned flight route for a user equipment (UE) configured for at least one UAS service; and

receiving, from the AMF, via the NEF, a notification message including second information on whether the UE is flying in the planned flight route,

wherein the first message further includes third information indicating a request for a report for the second information on whether the UE is flying in the planned flight route, and

wherein the first information on the planned flight route is related to a list of cells or a list of radio access node (RAN) node identifiers.

8 . The method of claim 7 , wherein the second information indicates whether the UE moves out of the area related to the planned flight route.

9 . The method of claim 7 , wherein the notification message further includes location information of the UE.

10 . An access and mobility management function (AMF) entity, in a wireless communication system, the AMF entity comprising:

a transceiver; and

at least one processor coupled to the transceiver and configured to:

receive, from an uncrewed aerial system (UAS) service supplier (USS) entity, via a network exposer function (NEF) entity, a first message including first information on a planned flight route,

identify whether the UE is flying in the planned flight route, and

transmit, to the USS entity, via the NEF entity, a notification message including second information on whether the UE is flying in the planned flight routein response to the identification,

wherein the first message further includes third information indicating a request for a report for the second information on whether the UE is flying in the planned flight route, and

wherein the first information on the planned flight route is related to a list of cells or a list of radio access node (RAN) node identifiers.

11 . The AMF entity of claim 10 , wherein the second information indicates whether the UE moves out of the area related to the planned flight route.

12 . The AMF entity of claim 10 , wherein the notification message further includes location information of the UE.

13 . An uncrewed aerial system (UAS) service supplier (USS) entity in a wireless communication system, the USS entity comprising:

a transceiver; and

at least one processor coupled to the transceiver and configured to:

transmit, to an access and mobility management function (AMF) entity, via a network exposer function (NEF) entity, a first message including first information on a panned flight route for a user equipment (UE) configured for at least one UAS service, and

receive, from the AMF entity, via the NEF entity, a notification message including second information on whether the UE is flying in the planned flight route,

wherein the first message further includes third information indicating a request for a report for the second information on whether the UE is flying in the planned flight route, and

wherein the first information on the planned flight route is related to a list of cells or a list of radio access node (RAN) node identifiers.

14 . The USS entity of claim 13 , wherein the second information indicates whether the UE moves out of the area related to the planned flight route.

15 . The USS entity of claim 13 , wherein the notification message further includes location information of the UE.
