5GMSd Application Function Supported Features

The release versions of the 5GMSd Application Function support differing sets of interfaces, as described by the different versions of the 3GPP specifications, and differing levels of feature support for those interfaces. The page attempts to capture the feature sets and specification versions for each release, starting with the most recent release or upcoming releases.

Key

Where a feature of the specifications is supported the entry will be marked with ☑, where it is being worked on and slated for the next release the feature will be marked with ✎ and where it is unimplemented in that version the feature will be marked with ☐.
