8. An apparatus comprising a session management function, the apparatus further comprising:
a receiver that receives a first request message comprising an indication that a protocol data unit session is to be released locally in the session management function; a processor that determines to delete a protocol data unit session context in the session management function; a transmitter that:
transmits a second request message comprising an indication to release the protocol data unit session; and
transmits a response message in response to the first request message.
9. The apparatus of claim 8, wherein the first request message is received from an access and mobility management function.
10. The apparatus of claim 8, wherein the second request message is transmitted to a user plane function associated with the protocol data unit session and comprises a session release request message.
11. The apparatus of claim 8, wherein the first request message comprises a session identifier indicating the protocol data unit session.
12. The apparatus of claim 8, wherein the first request message is a release session management context request message, a session release message, or a session update message.
13. The apparatus of claim 12, wherein the first request message further comprises a cause value or a cause type that indicates the protocol data unit session to be released.
14. The apparatus of claim 8, wherein the first request message further indicates whether a user equipment corresponding to the protocol data unit session is reachable.
