5G System; SideLink Positioning Key Management Services; Stage 3
The present document specifies the stage 3 protocol and data model for the Nslpkmf Service Based Interface to support ranging based service and sidelink positioning in 5G system. It provides stage 3 protocol definitions and message flows, and specifies the API for each service offered by the SLPKMF as specified in 3GPP TS 33.533 [2].
The 5G System stage 2 architecture and procedures for ranging based service and sidelink positioning are specified in 3GPP TS 23.586 [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 [6].
