How it Works

This section describes how this feature works.

When the SMF skips UDM subscription, then it stops sending the following messages:

  • Fetch-Subscription during session establishment

  • Subscribe-for-Notification during session establishment

  • Unsubscribe-to-Notification during session release and when the UDCM receives the UECM messages

The SMF allows any dynamic changes to the UDM subscription skip configuration. That is, new value is applicable for the new session being established. The existing sessions continue to use the old values.
