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 identifier: An identifier that refers to the particular service the NF service consumer session belongs to. In the context of application detection control, it refers to the application identifier used by the PCF in the PCC rule as specified in 3GPP TS 29.512 [8].

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.

MCS session: A session for which priority treatment is applied for allocating and maintaining radio and network resources to support the Mission Critical Service (MCS). MCS is defined in 3GPP TS 22.179 [45], 3GPP TS 22.280 [46], 3GPP TS 22.281 [47], and 3GPP TS 22.282 [48].

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.
