1  Scopep. 7

The present document studies the potential enhancements in CAPIF and application enablement frameworks (e.g. SEAL, EDGEAPP, vertical enabler layers) to support the subscriber-aware northbound API access (SNA), whose requirements are specified in TS 22.261.
This study takes into consideration the existing works for CAPIF (TS 23.222), SEAL (TS 23.434), and EDGEAPP (TS 23.558).
Any potential enhancements to security procedures related to CAPIF and application enablement frameworks (e.g. EDGEAPP, SEAL, vertical enabler layers) to support SNA are not in the scope of this study.
