Notes:
• If the new mapping option is configured, then this local configuration is given higher precedence.
• Use the remove diameter-result-code-mapping s6a { diameter-realm-not-served |

S1 NAS Cause Code Mapping
CSCva44545 - Enhancement to have more options under "s1-ue-context-release" command
This feature defines the cause code mapping for S1-NAS cause sent in the S1-UE-CONTEXT-RELEASE for
both ATTACH/TAU Rejects with a specific EMM cause code value or any EMM cause code value. S1 NAS
Cause Code Mapping is further explained in the following sections:

Feature Description
This feature is enhanced to achieve S1 NAS Cause Code Mapping with a specific EMM cause code or 'any'
EMM cause code value.
EMM cause code value.
Earlier, the S1 NAS cause code sent in the S1-UE CONTEXT-RELEASE was indicated as "Unspecified" for
most of the scenarios during ATTACH/TAU Rejects with a specific or any EMM cause code. The NAS cause
"Unspecified" reflects as an error resulting in RAN KPI degradation.

A new CLI configuration is implemented at an MME Service level to achieve a successful cause code mapping
during ATTACH and TAU Rejects. The newly configured S1 NAS cause is sent in the MME initiated
S1-UE-CONTEXT-RELEASE message after an ATTACH or TAU Reject with the specific EMM cause code
or 'any' EMM cause code.

S1-UE-CONTEXT-RELEASE message after an ATTACH or TAU Reject with the specific EMM cause code
or 'any' EMM cause code.
The 'any' EMM cause code is a new keyword introduced as part of the CLI configuration. This allows the
operator to map with any of the available EMM cause code value instead of a specific EMM cause code
value.
