Enforcement at N26 Call Flow

The enforcement restriction at N26 call flow type is also known as a handover process from 5G to 4G. During this handover process, the following observations are noted:

  • Restriction enforcement received from the UDM subscription, responses to the am-data part.

  • This response is a specific core type restriction which is equivalent only to EPC.

  • The AMF rejects the EBI assignment request from the SMF with a restricted EBI cause.
