External Network Slice Information
ENSI is a parameter used to identify and select a specific network slice instance for a UE when it is roaming or connecting to an external network. It enables the home network to provide slice selection information to the visited network, ensuring consistent service delivery across administrative domains.
Generic Network Slice Template
A standardized data model defining the characteristics and requirements of a network slice. It enables automated, vendor-agnostic slice lifecycle management by providing a common language for describing slice capabilities, performance, and service level agreements.
Network Slice Template
A standardized, machine-readable data model defining the structure, attributes, and requirements of a network slice. It enables automated slice lifecycle management by providing a blueprint for instantiation, configuration, and assurance, crucial for supporting diverse 5G services with varying needs.
Network Slice Admission Control
A control mechanism that ensures the number of UEs registered to a specific network slice does not exceed a configured maximum limit. It is crucial for maintaining slice performance, preventing congestion, and enabling operators to enforce service-level agreements and resource isolation.
Network Slice Admission Control Function
A dedicated network function that implements the Network Slice Admission Control (NSAC) policy. It maintains the current count of registered UEs per network slice and provides admission decisions to the AMF, acting as the central enforcement point for slice capacity limits.
Network Slice Access Group
A group identifier used in the RAN to associate a UE with a specific set of network slices. It enables the RAN to apply common policies and optimizations (like paging, resource allocation) for all UEs belonging to the same group of slices, improving RAN efficiency for slice-aware operations.
Network Slice Customer
An entity (e.g., enterprise, MVNO, or service provider) that requests and uses a network slice instance from a mobile network operator. The NSC defines the requirements for the slice, such as service characteristics and SLA, and is the beneficiary of the tailored connectivity and resource isolation provided by network slicing.
Network Slice Capability Enablement
A framework for enabling and exposing network slice capabilities to applications and verticals. It allows applications to discover, request, and utilize specific slice features, bridging the gap between network functionality and service requirements.
Network Slice Instance Identifier
A unique identifier for a Network Slice Instance (NSI), which is a deployed set of network functions and resources providing a complete logical network for a specific service type or tenant. It is the core identifier enabling the creation, management, and isolation of end-to-end network slices in 5G systems.
Network Slice Management
Network Slice Management (NSM) is a framework for the lifecycle management of network slices, including creation, modification, monitoring, and termination. It provides the management capabilities necessary to operate network slices as independent logical networks, ensuring they meet their specific Service Level Agreements (SLAs).
Network Slice Management Function
The Network Slice Management Function (NSMF) is a core management entity responsible for the management and orchestration of an end-to-end network slice. It translates service requirements into slice requirements and coordinates the lifecycle management of the slice across different network domains.
Network Slice Performance and Analytics
A framework for monitoring and analyzing the performance of network slices. It collects performance data and provides analytics to ensure slices meet their Service Level Agreements (SLAs). This is crucial for managing and assuring the quality of isolated network services.
Network Slice-Specific Authentication and Authorization
NSSAA is a security framework within 5G that performs authentication and authorization checks specific to a requested network slice. It ensures that a UE is not only authenticated for the core network but also explicitly authorized to access a particular slice, enabling enhanced security and service isolation for network slicing.
Network Slice-specific Authentication and Authorization Function
The NSSAAF is a 5G Core Network function that orchestrates Network Slice-Specific Authentication and Authorization (NSSAA). It acts as a proxy between the AMF and external AAA servers, managing the EAP-based authentication dialogue to authorize a UE for a specific network slice.
Network Slice Selection Assistance Information
NSSAI is a key parameter in 5G that identifies the network slices a UE wants to use. It consists of one or more S-NSSAIs, each uniquely identifying a slice. The network uses this information to route the UE's connection to the appropriate network functions supporting the requested slices.
Network Slice Selection Function
The NSSF is a core network function in 5G that selects the appropriate network slice instance for a user equipment (UE) based on subscription data, requested service, and network conditions. It is essential for enabling customized network slices that support diverse 5G use cases with varying requirements for latency, bandwidth, and reliability.
Network Slice Subnet Instance
An NSSI is a managed instance of a subset of resources (e.g., a group of network functions) that forms part of a complete end-to-end Network Slice Instance (NSI). It represents a deployable, manageable segment of a network slice, allowing for modular construction and independent lifecycle management of slice components.
Network Slice Selection Policy
The NSSP is a set of rules configured in the User Equipment (UE) that guides the device in selecting and requesting the appropriate network slice(s) for its applications. It maps application identifiers or traffic descriptors to specific S-NSSAIs, enabling automatic and optimized slice selection at the device level.
Network Slice Simultaneous Registration Group
A group of network slices for which a UE can be simultaneously registered. It enables a single device to maintain active registrations across multiple network slices, supporting diverse service requirements concurrently without needing to re-register when switching between services.
Private Network Slice Type
P-NEST is a 3GPP-defined network slice type specifically designed for private mobile networks. It provides a standardized template that defines the characteristics, capabilities, and service requirements for slices serving enterprise, industrial, or localized deployments, enabling consistent implementation and interoperability.
Public Network Integrated Non-Public Network
PNI-NPN is a 3GPP architecture that enables the provisioning of Non-Public Networks (NPNs) using the infrastructure of a public mobile network operator. It allows for dedicated, isolated network slices to serve private enterprise use cases like factories, while leveraging the operator's existing radio and core network assets.
Single Network Slice Selection Assistance Information
S-NSSAI (Single Network Slice Selection Assistance Information) is a key identifier in 5G network slicing, used to select a specific network slice instance for a UE. It consists of a Slice/Service Type (SST) and an optional Slice Differentiator (SD). This enables the network to provide tailored connectivity and services with specific characteristics like enhanced mobile broadband, ultra-reliable low latency, or massive IoT.
