3GPP TS 23.501 version 15.3.0
5G QoS Flow: The finest granularity for QoS forwarding treatment in the 5G System. All traffic mapped to the same
5G QoS Flow receive the same forwarding treatment (e.g. scheduling policy, queue management policy, rate shaping
policy, RLC configuration, etc.). Providing different QoS forwarding treatment requires separate 5G QoS Flow.
5G QoS Identifier: A scalar that is used as a reference to a specific QoS forwarding behaviour (e.g. packet loss rate,
packet delay budget) to be provided to a 5G QoS Flow. This may be implemented in the access network by the 5QI
referencing node specific parameters that control the QoS forwarding treatment (e.g. scheduling weights, admission
thresholds, queue management thresholds, link layer protocol configuration, etc.).
5G System: 3GPP system consisting of 5G Access Network (AN), 5G Core Network and UE.
Allowed NSSAI: NSSAI provided by the Serving PLMN during e.g. a Registration procedure, indicating the S-NSSAIs
values the UE could use in the Serving PLMN for the current registration area.
Allowed Area: Area where the UE is allowed to initiate communication as specified in clause 5.3.2.3.
AMF Region: An AMF Region consists of one or multiple AMF Sets.
AMF Set: An AMF Set consists of some AMFs that serve a given area and Network Slice(s). AMF Set is unique within
an AMF Region and it comprises of AMFs that support the same Network Slice(s). Multiple AMF Sets may be defined
per AMF Region.
Application identifier: An identifier that can be mapped to a specific application traffic detection rule.
AUSF Group ID: This refers to one or more AUSF instances managing a specific set of SUPIs.
Configured NSSAI: NSSAI provisioned in the UE applicable to one or more PLMNs.
DN Access Identifier (DNAI): Identifier of a user plane access to one or more DN(s) where applications are deployed.
Emergency Registered: A UE is considered Emergency Registered over an Access Type in a PLMN when in limited
service state and registered for emergency services only over this Access Type in this PLMN.
Endpoint Address: An address used by a NF service consumer to access the NF service (i.e. to invoke service
operations) provided by a NF service provider. An Endpoint Address is represented in the syntax of Uniform Resource
Identifier (e.g. part of Resource URI of the NF service API).
Expected UE Behaviour: Set of parameters provisioned by an external party to 5G network functions on the foreseen
or expected UE behaviour, see clause 5.20.
Forbidden Area: An area where the UE is not allowed to initiate communication as specified in clause 5.3.2.3.
GBR QoS Flow: A QoS Flow using the GBR resource type or the Delay-critical GBR resource type and requiring
guaranteed flow bit rate.
Initial Registration: UE registration in RM-DEREGISTERED state as specified in clause 5.3.2.
Local Area Data Network: a DN that is accessible by the UE only in specific locations, that provides connectivity to a
specific DNN, and whose availability is provided to the UE.
Local Break Out (LBO): Roaming scenario for a PDU Session where the PDU Session Anchor and its controlling
SMF are located in the serving PLMN (VPLMN).
Mobility Pattern: Network concept of determining within the AMF the UE mobility parameters as specified in
clause 5.3.2.4.
Mobility Registration Update: UE re-registration when entering new TA outside the TAI List as specified in
clause 5.3.2.
MPS-subscribed UE: A UE having a USIM with MPS subscription.
NGAP UE association: The logical per UE association between a 5G-AN node and an AMF.
NGAP UE-TNLA-binding: The binding between a NGAP UE association and a specific TNL association for a given
UE.
