Indicating a packet data unit session as unavailable
Apparatuses, methods, and systems are disclosed for indicating a packet data unit session as unavailable. One apparatus includes a processor that determines that at least one packet data unit session is unavailable. The apparatus includes a transmitter that transmits information indicating that the at least one packet data unit session is to be released.
1. A method of a first access and mobility management function, the method comprising:
receiving a first request message indicating that a protocol data unit session is rejected in a new registration area;
determining to release the protocol data unit session; and
transmitting a second request message indicating to release the protocol data unit session.
2. The method of claim 1 , wherein the first request message is received from a second access and mobility management function.
3. The method of claim 1 , wherein the second request message is transmitted to a session management function associated with the protocol data unit session.
4. The method of claim 1 , wherein the second request message is transmitted as part of a release session management context procedure.
5. The method of claim 1 , wherein the second request message indicates to release the protocol data unit session locally in the session management function.
6. The method of claim 1 , wherein the first request message comprises a session identifier indicating the protocol data unit session.
7. The method of claim 1 , wherein the first request message comprises network slice selection assistance information indicating the protocol data unit session.
8. The method of claim 1 , wherein the first request message is part of a registration status update message.
9. The method of claim 8 , wherein the first request message comprises a cause value that indicates the protocol data unit session to be released.
10. An apparatus comprising a first access and mobility management function, the apparatus further comprising:
a receiver that receives a first request message indicating that a protocol data unit session is rejected in a new registration area;
a processor that determines to release the protocol data unit session; and
a transmitter that transmits a second request message indicating to release the protocol data unit session.
11. The apparatus of claim 10 , wherein the first request message is received from a second access and mobility management function.
12. The apparatus of claim 10 , wherein the second request message is transmitted to a session management function associated with the protocol data unit session.
13. The apparatus of claim 10 , wherein the second request message is transmitted as part of a release session management context procedure.
14. The apparatus of claim 10 , wherein the second request message indicates to release the protocol data unit session locally in the session management function.
15. The apparatus of claim 10 , wherein the first request message comprises a session identifier indicating the protocol data unit session.
16. The apparatus of claim 10 , wherein the first request message comprises network slice selection assistance information indicating the protocol data unit session.
17. The apparatus of claim 10 , wherein the first request message is part of a registration status update message.
18. The apparatus of claim 10 , wherein the first request message comprises a cause value that indicates the protocol data unit session to be released.
