emm_cause_number specifies the EMM code replacement integer. The system accepts a value in the range 0–255, however, the standards-compliant
valid values are in the range 2–111.

When UDM sends Deregistration to AMF, and AMF clears the subscriber information.
-
When SMF triggers clean up of a session for that particular SUPI, and notifies AMF to clear the context.

When MME is in N26 procedure and communicates with AMF to retrieve the SM and MM contexts, but not successful.
Use unknown-ue-context command to configure the returned cause code to a UE, when a UE context transfer fails from a peer MME.
By default, the MME sends #9 - MS identity cannot be derived by the network cause code to UE.

Use unknown-ue-context command to configure the returned cause code to a UE, when a UE context transfer fails from a peer SGSN.
By default, the MME sends #9 - MS identity cannot be derived by the network cause code to UE.

When the MME interacts with S-GW or P-GW, and it doesn’t get response.
-
When the S-GW or the P-GW is down
MME returns separate cause codes for Attach and TAU procedures optionally. This capability is available for all the defined
EMM cause codes except no-bearers-active which is defined for TAU procedures.

Use no-bearers-active command to configure the returned cause code to a UE, when a UE context received from peer SGSN (during TAU procedure) doesn't
contain active PDP context.
By default, the MME sends #40 - No PDP context activated cause code when encountering this condition.

Use unknown-ue-context command to configure the returned cause code to a UE, when peer node resolution isn’t successful.
By default, the MME sends #9 - MS identity cannot be derived by the network cause code to UE.
