Limitations

This feature has the following limitations in this release:

  • The AMF does not support the N26-based IDLE mode handover procedure, and the N14-based UE Context Transfer scenarios with the emergency PDU and Emergency Registered Subscriber requests.

  • For the N26-based handover, AMF supports only the IMSI-based emergency registered handover procedures. However, the AMF does not support IMEI-based handover as the MME requires both IMSI and IMEI information.

  • The AMF does not support the emergency services in the following scenarios:

    • E-call interactions

    • Emergency service fallback

    • Congestion interactions

    • Identification, authentication, EIR and UDM interaction

    • Configuration change in emergency profile communication to UE

    • Security procedure failure scenario for normal registration

    • Support for EPS type of service request is not available
