Abstract
A wireless device and an Access and Mobility Management Function (AMF) and methods performed by a wireless device and an AMF, respectively.
Claims23
A method implemented in a wireless device, the method comprising:
- transmitting a transport message to an Access and Mobility Function (AMF), wherein the transport message comprises a session management message to be forwarded by the AMF to a Session Management Function (SMF);
- and
- receiving a status message transmitted by the AMF, wherein the status message comprises at least a portion of the transport message and an indication of non-delivery of the session management message, wherein
- the portion of the transport message comprises the session management message, and
- the indication of non-delivery is an indication of non-delivery of the session management message by the AMF to the SMF.
2 more elements
A non-transitory computer readable medium storing a computer program comprising instructions for configuring a wireless device to:
- transmit a transport message to an Access and Mobility Function (AMF), wherein the transport message comprises a session management message, to be forwarded by the AMF to a Session Management Function (SMF);
- and
- process a status message transmitted by the AMF, wherein the status message comprises at least a portion of the transport message and an indication of non-delivery of the session management message, wherein
- the portion of the transport message comprises the session management message, and
- the indication of non-delivery is an indication of non-delivery, by the AMF, to the Session Management Function.
2 more elements
A wireless device, the wireless device comprising:
- a receiver;
- a transmitter;
- and
- processing circuitry coupled to the receiver and the transmitter, wherein the wireless device is configured to:
- employ the transmitter to transmit a transport message to an Access and Mobility Function (AMF), wherein the transport message comprises a session management message, to be forwarded by the AMF to a Session Management Function (SMF);
- and
- process a status message transmitted by the AMF, wherein the status message comprises at least a portion of the transport message and an indication of non-delivery of the session management message, wherein
- the portion of the transport message comprises the session management message, and
- the indication of non-delivery is an indication of non-delivery, by the AMF, to the Session Management Function.
6 more elements
A method performed by an Access and Mobility Management Function (AMF), comprising:
- receiving a transport message transmitted by a wireless device, wherein the transport message comprises a session management message;
- determining whether the session management message can be forwarded to a Session Management Function (SMF);
- as a result of determining that the session management message cannot be forwarded to a SMF, transmitting a status message to the UE, the status message comprising at least a portion of the transport message, wherein the portion of the transport message comprises the session management message and an indication of non-delivery of the session management message to a SMF.
