name: SDF
full_form: Service Data Flow
context: As specified with PCC Rule definition in clause 6.3.1 TS 23.503 [202], during MA PDU session handling by the SMF, PCC Rules can be activated with a MA PDU session control information attribute including an optional rating group for Non-3GPP access, in addition to the rating group included in the PCC rule description. When the MA PDU session control information in a PCC Rule includes a separate rating group for Non-3GPP access, it shall be used by the SMF for the SDF traffic carried via non-3GPP access. The PCC Rule rating group shall be used for the SDF traffic carried via 3GPP access, and all other charging related attributes in the PCC rule shall be the used for both accesses. When the MA PDU session control information in a PCC Rule does not include any rating group for Non-3GPP access, the PCC Rule rating group shall be used by the SMF for the SDF traffic carried via both accesses (i.e. 3GPP access and non-3GPP access).
description: Service Data Flow (SDF) refers to the flow of data related to a specific service or application in a telecommunications network, particularly in the context of Policy and Charging Control (PCC) rules for Multi-Access (MA) PDU sessions.
explanation: The provided context from 3GPP TS 32.255 describes SDF as part of the handling of MA PDU sessions by the Session Management Function (SMF), specifically in relation to PCC rules and rating groups for Non-3GPP access. This indicates that SDF is a concept related to data flows within telecommunications, but it does not fit neatly into other categories like Network, Protocol, or Interface.
