Session and Service Continuity Mode Selection

The SSC mode selection policy is used to determine the type of session and service continuity mode associated with an application or group of applications for the UE. The SMF receives the list of supported SSC modes and the default SSC mode per DNN per S-NSSAI as part of the subscription information from the UDM.

To select the SSC mode, when UE sends SSC mode in PDU session establishment request, it is checked against subscriber data and local SMF configuration and allowed SSC mode is determined.

Important

In this release, SMF supports only SSC mode-1.
