Uncrewed Aerial Systems Network Function (UAS-NF); Aerial Management Services; Stage 3
The present document specifies the stage 3 protocol and data model for the UAS-NF functionality of the Nnef Service Based Interface. It provides stage 3 protocol definitions and message flows, and specifies the API for each service offered by the NEF (UAS-NF).
The 5G System stage 2 architecture and procedures are specified in 3GPP TS 23.501 [2] and 3GPP TS 23.502 [3].
The Technical Realization of the Service Based Architecture and the Principles and Guidelines for Services Definition are specified in 3GPP TS 29.500 [4] and 3GPP TS 29.501 [5].
The Uncrewed Aerial System Network Function (UAS-NF) provides the UAS-specific NEF services to NF service consumers (e.g. AMF, SMF). The UAS-NF is functionality within the NEF.
