1 Scope
The present specification provides the stage 3 definition of the Policy Authorization Service of the 5G System.
The 5G System Architecture 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 Architecture 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 session is bound.
