Feature Description

AMF supports the error handling for the following interfaces:

  • SBI—AMF interaction across various 5G NF's

  • REST-EP—AMF interaction to NGAP, and NAS (towards UE)

AMF validates the syntax and semantic errors for each attribute during SBI message validation. It evaluates the mandatory, conditional, and optional attributes in the following:

  • NGAP content

  • NAS content

  • Each SBI interface message

Note

You can define the local cause code-mapping values for Mobility-Management, while rejecting the NAS messages under failure scenarios.

Validation of the NGAP and NAS optional IEs aren’t supported.
