The 5G System Architecture

40、is defined in 3GPP TS 23.501 2. The stage 2 definition and related procedures for the Npcf Policy Authorization Service are specified in 3GPP TS 23.502 3 and 3GPP TS 23.503 4. The 5G System stage 3 call flows are provided in 3GPP TS 29.513 7. The Technical Realization of the Service Based Architectu

41、re and the Principles and Guidelines for Services Definition are specified in 3GPP TS 29.500 5 and 3GPP TS 29.501 6. The Policy Authorization Service is provided by the Policy Control Function (PCF). This service creates policies as requested by the authorised AF for the PDU Session to which the AF

42、session is bound. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific
