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.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in 3GPP TR 21.905 [1] and the following
apply. A term defined in the present document takes precedence over the definition of the same term, if any, in
3GPP TR 21.905 [1].
Application Function (AF): Element offering application(s) that use PDU session resources.
AF application session context: Application level session context established by an application level signalling
protocol offered by the AF that requires a session context set-up with explicit session context description before the use
of the service.
MPS session: A session for which priority treatment is applied for allocating and maintaining radio and network
resources to support the Multimedia Priority Service (MPS). MPS is defined in 3GPP TS 22.153 [23].
PCC rule: Set of information enabling the detection of a service data flow and providing parameters for policy control
and/or charging control.
Service information: Set of information conveyed from the AF/NEF to the PCF by the Npcf_PolicyAuthorization
service to be used as a basis for PCC decisions at the PCF, including information about the AF/NEF application session
context (e.g. application identifier, type of media, bandwidth, IP address and port number).
Service data flow: An aggregate set of packet flows.
3.2 Abbreviations
For the purposes of the present document, the abbreviations given in 3GPP TR 21.905 [1] and the following apply. An
abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in

4 Npcf_PolicyAuthorization Service
4.1 Service Description
4.1.1 Overview
The Npcf_PolicyAuthorization Service, as defined in 3GPP TS 23.502 [3] and in 3GPP TS 23.503 [4], is provided by
the Policy Control Function (PCF).
The Npcf_PolicyAuthorization service authorises an AF request and creates policies as requested by the authorised NF
service consumer for the PDU session to which the AF session is bound to. This service allows the NF service
consumer to subscribe/unsubscribe to the notification of events (e.g. Access Type and RAT type, PLMN identifier,
usage report).
4.1.2 Service Architecture
The 5G System Architecture is defined in 3GPP TS 23.501 [2]. The Policy and Charging control related 5G architecture
is also described in 3GPP TS 23.503 [4] and 3GPP TS 29.513 [7].
The only known NF service consumers of the Npcf_PolicyAuthorization service are the Application Function (AF) and
the Network Exposure Function (NEF).
The Npcf_PolicyAuthorization service is provided by the PCF and consumed by the AF and the NEF, as shown in
figure 4.1.2-1 for the SBI representation model an
