Authentication and Authorization for Aerial System

1 . A method comprising:

receiving, by a mobility management function, a message indicating a revocation of an authentication and/or authorization (AA) of an aerial service of a wireless device; and

sending, by the mobility management function to the wireless device and after an expiration of a time period in which a session associated with the aerial service is available after the revocation, a release message indicating a release of the session.

2 . The method of claim 1 , wherein the release message is a packet data unit session release command.

3 . The method of claim 1 , further comprising determining, by the mobility management function, that the session is associated with the aerial service.

4 . The method of claim 3 , wherein determining that the session is associated with the aerial service is based on at least one of:

subscription information of the wireless device;

a data network name (DNN) associated with the session;

single network slice selection assistance information (S-NSSAI) associated with the session; and

local policy.

5 . The method of claim 1 , further comprising sending, by the mobility management function to the session management entity, a session management message.

6 . The method of claim 5 , wherein the session management message is an update session management context request message.

7 . The method of claim 5 , wherein the session management message indicates the release of the session.

8 . The method of claim 5 , wherein the session management message indicates that the revocation is a release cause for the release of the session.

9 . A mobility management function comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the mobility management function to perform operations comprising:

receiving a message indicating a revocation of an authentication and/or authorization (AA) of an aerial service of a wireless device; and

sending, to the wireless device and after an expiration of a time period in which a session associated with the aerial service is available after the revocation, a release message indicating a release of the session.

10 . The mobility management function of claim 9 , wherein the release message is a packet data unit session release command.

11 . The mobility management function of claim 9 , wherein the operations further comprise determining that the session is associated with the aerial service.

12 . The mobility management function of claim 11 , wherein determining that the session is associated with the aerial service is based on at least one of:

subscription information of the wireless device;

a data network name (DNN) associated with the session;

single network slice selection assistance information (S-NSSAI) associated with the session; and

local policy.

13 . The mobility management function of claim 9 , wherein the operations further comprise sending, to the session management entity, a session management message.

14 . The mobility management function of claim 13 , wherein the session management message is an update session management context request message.

15 . The mobility management function of claim 13 , wherein the session management message indicates the release of the session.

16 . The mobility management function of claim 13 , wherein the session management message indicates that the revocation is a release cause for the release of the session.

17 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause a mobility management function to perform operations comprising:

receiving a message indicating a revocation of an authentication and/or authorization (AA) of an aerial service of a wireless device; and

sending, to the wireless device and after an expiration of a time period in which a session associated with the aerial service is available after the revocation, a release message indicating a release of the session.

18 . The non-transitory computer-readable medium of claim 17 , wherein the release message is a packet data unit session release command.

19 . The non-transitory computer-readable medium of claim 17 , wherein the operations further comprise determining that the session is associated with the aerial service.

20 . The non-transitory computer-readable medium of claim 19 , wherein determining that the session is associated with the aerial service is based on at least one of:

subscription information of the wireless device;

a data network name (DNN) associated with the session;

single network slice selection assistance information (S-NSSAI) associated with the session; and

local policy.
