5G Core Network Training 2026: Complete Module-by-Module Guide to 5G Core, SBA, Slicing & Signaling
Introduction 5G Core Network Training
5G Core Network Training Behind the higher speeds, lower latency and massive device connectivity is a completely different network architecture designed for flexibility, programmability and service innovation.
At the center of this transformation is the 5G Core.
5G Core Network Training helps engineers understand how the 5G Core is designed, how its network functions communicate, how services are discovered, how network slices are created, how signaling procedures work and how operators can migrate from 4G EPC toward 5G Core architecture.
The uploaded course curriculum follows a structured learning journey covering 5G Core architecture, Service-Based Architecture, protocols, network slicing, NRF, signaling and EPC-to-5GC migration. It also includes practical technical exercises and advanced capstone projects.
This structure is particularly relevant in 2026 because telecom engineering is increasingly connected with cloud computing, software-defined networking, automation, edge computing, private networks, artificial intelligence and 6G research.
Instead of studying 5G Core as a collection of technical terms, engineers should understand how the complete system works.
What happens when a device registers?
How does authentication take place?
How does a PDU session get established?
How does a network function discover another network function?
How does network slicing work?
How does a 5G network move from NSA to SA?
How can telecom capabilities be exposed to applications?
These are the questions that turn theoretical knowledge into practical engineering skills.
This guide follows the same module-oriented structure provided in the course PDF and expands each module into a practical learning roadmap.

Conclusion
Module 1: Benefits and Design of 5G Core Network
The first step toward understanding 5G Core is understanding why the architecture changed. The transition from LTE EPC to 5GC is not simply a technology upgrade. It represents a change in the way mobile networks are designed, deployed, managed and exposed to applications.
The course PDF begins with 3GPP updates, 5G architectures and options, the definition of the core network, benefits of 5G Core and the principles behind core-network transformation. It also introduces concepts such as CUPS and Service-Based Architecture.
3GPP Update
3GPP specifications provide the technical foundation for modern cellular systems. Engineers working with 5G Core need to become comfortable reading specifications rather than relying only on simplified diagrams.
3GPP terminology appears throughout architecture documents, signaling procedures, network-function definitions and interface descriptions.
For a telecom engineer, specification-reading is therefore a practical skill. It helps engineers understand what a network function is expected to do, how procedures operate and how different components interact.
5G Architectures and 5G Options
5G architecture can be deployed through different migration paths.
Two important deployment approaches are:
Non-Standalone 5G
Standalone 5G
NSA uses 5G radio technology while continuing to depend on parts of an existing 4G LTE/EPC architecture. SA introduces a dedicated 5G Core.
Understanding these options is important because telecom networks evolve progressively. Operators need strategies that allow existing infrastructure and new 5G technologies to coexist.
Core Network Definition
The core network is responsible for central control and connectivity functions. It manages areas such as access, mobility, authentication, session management, policy and user-plane traffic.
In 5G, these responsibilities are distributed across specialized network functions.
This modular design allows the network to become more flexible and software-oriented.
Benefits of 5G Core Network
5G Core provides an architecture suitable for a broad range of services.
Important benefits include:
Flexible network architecture
Service-based communication
Cloud-oriented deployment
Network slicing
Programmable services
Improved scalability
Support for enterprise services
Better integration with edge computing
Support for automation
Integration with modern software technologies
The important point is that these capabilities work together. Network slicing, edge computing, APIs and cloud infrastructure become more powerful when supported by an appropriately designed core network.
Main Principles of 5G Core Transformation
5G Core transformation involves moving toward modular network functions, software-based infrastructure and service-oriented communication.
Two important concepts introduced in the course are CUPS and SBA.
CUPS separates control-plane and user-plane responsibilities. This allows user-plane resources to be positioned according to traffic requirements.
Service-Based Architecture takes modularity further by allowing network functions to expose services that other authorized functions can consume.
Module 2: 5G Service-Based Architecture and 5G Core Protocols
Module 2 moves from high-level architecture toward the network functions and protocols that make 5GC operate.
The PDF specifically covers 4G Core versus 5G Core, 5G SBA network functions including SMF, UPF, NRF and AUSF, EPC-to-5GC mapping, and service-based interface protocols such as HTTP/2, REST, TLS and X.509.
4G Core vs 5G Core
The LTE EPC architecture traditionally includes functions such as MME, SGW, PGW and HSS.
5GC introduces a more modular collection of network functions.
Examples include:
AMF
SMF
UPF
NRF
AUSF
UDM
PCF
NSSF
NEF
Understanding the differences between EPC and 5GC is essential for migration, troubleshooting and interoperability work.
5G SBA Network Functions
Service-Based Architecture divides responsibilities among specialized network functions.
AMF
The Access and Mobility Management Function handles important access and mobility management responsibilities.
SMF
The Session Management Function manages PDU sessions and controls relevant user-plane behavior.
UPF
The User Plane Function forwards user traffic and provides connectivity toward external data networks.
NRF
The Network Repository Function supports network-function registration and discovery.
AUSF
The Authentication Server Function participates in authentication procedures.
UDM
The Unified Data Management function provides subscriber-related data management.
PCF
The Policy Control Function provides policy-control capabilities.
NSSF
The Network Slice Selection Function participates in network-slice selection.
NEF
The Network Exposure Function supports controlled exposure of network capabilities to authorized applications and services.
Mapping 5GC to EPC Functions
Learning mapping between EPC and 5GC is useful because many telecom professionals already understand LTE.
For example, rather than memorizing completely new terminology, engineers can understand how responsibilities previously handled by EPC functions are distributed across the new 5G Core architecture.
This knowledge becomes particularly useful when working on migration projects.
Service-Based Interface Protocols
SBA brings several software and networking concepts into the telecom core.
The course specifically includes:
HTTP/2
REST
TLS
X.509
This is an important indication of how telecom engineering is changing.
A modern core engineer needs more than traditional telecom signaling knowledge. Networking, APIs, certificates, security and software concepts are becoming increasingly relevant.
Module 3: Network Slicing & Technical Slice Components
Network slicing is one of the major capabilities associated with advanced 5G architecture.
The course curriculum covers the definition and benefits of network slicing, NSSAI, SST, SD, NSI, types of NSSAI, slice selection and slice-selection call flows.
What Is Network Slicing?
Network slicing allows a common physical infrastructure to support logically differentiated network environments.
Different services can have different requirements.
For example:
A manufacturing application may require predictable connectivity.
A video service may require high bandwidth.
A large IoT deployment may prioritize massive device connectivity.
Network slicing provides a framework for creating logical service environments suited to these different requirements.
Technical Slice Components
Important terms include:
NSSAI
NSSAI stands for Network Slice Selection Assistance Information.
It assists the network in identifying suitable network-slice information.
SST
SST, or Slice/Service Type, identifies the expected service characteristics associated with a slice.
SD
SD stands for Slice Differentiator. It can help distinguish slices that share the same SST.
NSI
NSI stands for Network Slice Instance and refers to the deployed instance supporting a particular slice.
Understanding these terms is essential for analyzing slice-selection procedures and call flows.
Slice Selection Procedure
Slice selection is not simply a configuration value.
It involves procedures through which the network determines which slice or slices should be used for a service.
For engineers, studying the call flow is particularly important.
A good learning approach is:
Identify the UE requirements.
Identify the slice information.
Follow the signaling.
Identify the participating network functions.
Determine how the selected slice is represented.
Analyze the resulting session behavior.
Module 4: Types of Slicing and Features From End to End
The fourth module expands network slicing beyond its basic definition.
The PDF covers slice attributes, slice evolution, pre-slicing, static and dynamic slicing, NFV, SDN, orchestration, lifecycle management and slicing across RAN, transport and core. It also includes QoS comparison between NSA and SA.
Static and Dynamic Slicing
Static slicing involves predefined network configurations.
Dynamic slicing provides greater flexibility by allowing resources and services to be adjusted according to changing requirements.
The choice depends on the service architecture, orchestration capabilities, business requirements and operational model.
NFV, SDN and Orchestration
Network Function Virtualization enables network functions to run on software-based infrastructure.
Software-Defined Networking separates network control concepts from forwarding infrastructure and enables more programmable network management.
Orchestration coordinates resources, network functions and service lifecycles.
Together, NFV, SDN and orchestration contribute to the automation of modern telecom networks.
Slice Lifecycle Management
A network slice needs to be managed throughout its lifecycle.
Typical lifecycle stages can include:
Design
Creation
Configuration
Activation
Monitoring
Modification
Scaling
Decommissioning
This is where telecom engineering increasingly overlaps with cloud operations and DevOps concepts.
RAN, Transport and Core Slicing
End-to-end slicing is not limited to the core.
The RAN, transport network and core network all need to participate in supporting the required service characteristics.
This is why engineers studying slicing need an end-to-end understanding rather than knowledge of only one domain.
Module 5: 5G Slicing Use Cases
The course identifies several industries with strong potential requirements for network slicing, including automotive, healthcare, public-sector services, government emergency services, manufacturing and gaming.
Automotive Industry
Connected vehicles can generate different types of traffic, including telemetry, infotainment, safety-related information and application data.
Different connectivity requirements can make network slicing relevant to automotive architectures.
Healthcare Industry
Healthcare environments may connect medical devices, monitoring systems and digital applications.
Network architecture must be designed around security, reliability and application requirements.
Public Sector and Emergency Services
Emergency organizations may require dedicated communication capabilities during critical situations.
Logical service separation can help support different operational requirements when properly engineered.
Manufacturing
Manufacturing is one of the most important private 5G use cases.
Factories can connect:
Robots
Cameras
Sensors
Industrial controllers
Automated guided vehicles
Monitoring systems
Combining private 5G, edge computing and network slicing can create flexible industrial connectivity architectures.
Gaming
Gaming applications can require responsive connectivity and substantial data throughput.
Edge computing can complement connectivity by placing selected processing resources closer to users.
Module 6: Focus on 5G NRF
The Network Repository Function is a particularly important component of Service-Based Architecture.
The course dedicates a complete module to NRF and covers its role, service framework engine, NF service mechanisms and the AMF journey involving registration and discovery.
NRF Role and Service Framework
NRF maintains information related to available network functions and their supported services.
In a service-oriented architecture, a network function needs to know where another suitable network function is available.
NRF helps provide this discovery mechanism.
NF Registration
When a network function becomes available, it can register information about itself.
This information enables other network functions to discover relevant services.
NF Discovery
Discovery allows one network function to identify another network function that provides the required service.
This creates a dynamic service-oriented model.
For an engineer, understanding registration and discovery is important because many SBA procedures depend on network-function availability and service discovery.
AMF Journey Using NRF
The course specifically includes the AMF journey using NRF.
Studying this as a call-flow exercise helps engineers understand:
Registration
Service discovery
Network-function interaction
Service availability
SBA communication
This is much more useful than learning NRF only as a definition.
Module 7: 5G Signaling in 5G Core
Signaling is fundamental to mobile networks.
The PDF dedicates Module 7 to mobile signaling, its evolution and the main components of 5G signaling.
Introduction to Mobile Signaling
Signaling allows network components to coordinate operations.
It is involved in procedures such as:
Registration
Authentication
Mobility
Session establishment
Session modification
Session release
Network selection
Service discovery
An engineer troubleshooting a 5G network needs to understand the signaling sequence behind each procedure.
Evolution of Mobile Signaling
Mobile signaling has evolved considerably across generations.
Earlier mobile systems used architectures and protocols suited to their technology generation.
LTE introduced EPC-based signaling and architecture.
5G introduces a service-based core with new network functions and service-based communication mechanisms.
Understanding this evolution makes it easier for experienced telecom engineers to transition from 4G to 5G.
5G Signaling Call Flows
Call flows should be treated as practical engineering tools.
When a procedure fails, engineers can trace:
Which function initiated the procedure.
Which function received the request.
Whether authentication succeeded.
Whether required services were discovered.
Whether policy information was available.
Whether session establishment completed.
Where an error occurred.
This methodology is useful in protocol testing, log analysis, troubleshooting and network operations.
Module 8: Migration Scenarios From EPC to 5GC
The final core-technology module in the PDF focuses on migration.
It covers movement from 5G NSA to 5G SA, EPC–5GC interworking, 4G-to-5G migration strategies and migration scenarios from 4G Core to 5G Core.
Moving From 5G NSA to 5G SA
NSA allows operators to introduce 5G NR while continuing to use existing LTE/EPC infrastructure.
SA introduces the 5G Core and enables a more complete 5G architecture.
Understanding the differences between the two is important for engineers working on deployment and optimization.
EPC and 5GC Interworking
Migration does not necessarily happen instantly.
Existing EPC systems may need to interwork with newer 5G Core infrastructure during network evolution.
Engineers therefore need to understand both architectures and the interfaces or procedures involved in coexistence.
4G to 5G Migration Strategy
A migration strategy must consider:
Existing infrastructure
Subscriber systems
RAN
Core
Transport
Cloud infrastructure
Security
Operations
Service continuity
Enterprise requirements
The objective is not simply to replace hardware. It is to evolve the network while maintaining services.
What Is MEC in 5G?
MEC, or Multi-access Edge Computing, is an important complementary technology for 5G networks.
MEC moves computing resources closer to users and devices. Instead of sending every application request to a distant centralized cloud, selected workloads can be processed closer to the access network.
This can be particularly valuable for applications where responsiveness matters.
Examples include:
Industrial automation
Video analytics
Connected vehicles
AR/VR
Robotics
Smart manufacturing
Enterprise applications
MEC should be understood alongside the 5G Core rather than as a replacement for it.
The core provides connectivity and network control, while edge infrastructure provides computing resources closer to the application users.
Benefits of Edge Computing
Edge computing can provide several architectural advantages.
Lower Network Distance
Processing data closer to the user can reduce the network path between the application and device.
Reduced Backhaul
Local processing can reduce the amount of raw data that needs to travel to centralized cloud environments.
Faster Application Response
Applications that require frequent interaction can benefit from nearby processing resources.
Local Data Processing
Sensitive or high-volume data can potentially be processed locally before selected information is sent to a centralized environment.
Industrial Integration
Factories can combine 5G connectivity, edge computing, AI and industrial applications into a single architecture.
The most useful way to understand edge computing is through practical use cases rather than definitions alone.
MEC Architecture
A typical MEC environment can be understood through several layers.
User Equipment: Devices generate application traffic.
5G RAN: Provides wireless connectivity.
5G Core: Provides session management, policy, connectivity and user-plane control.
Edge Infrastructure: Provides local computing resources.
Applications: Run workloads such as AI inference, video analytics, industrial applications and enterprise services.
The UPF can play an important role in connecting user traffic toward suitable data networks and edge environments.
This makes knowledge of 5G Core particularly relevant for engineers working with MEC.
Role of NEF in 5G Core
NEF stands for Network Exposure Function.
It provides controlled exposure of selected network capabilities and information through standardized interfaces.
This becomes increasingly important as telecom networks evolve from connectivity platforms into programmable service platforms.
For example, an authorized application may need access to selected network information or capabilities.
Instead of providing direct access to internal network functions, controlled exposure mechanisms can provide an appropriate interface.
This creates a bridge between telecom infrastructure and enterprise applications.
NEF APIs and Exposure Functions
API-based network exposure is an important concept for modern telecom engineering.
A simplified exposure architecture can involve:
Application → API → NEF → 5G Core Network Functions
The exact implementation depends on the supported capability and deployment.
Important concepts include:
API security
Authorization
Application Functions
Network capability exposure
Event notifications
Policy
Traffic influence
Location-related capabilities
QoS-related capabilities
Engineers working with NEF therefore need knowledge of both telecom architecture and software APIs.
MEC vs Cloud Computing
MEC and centralized cloud computing are complementary.
Feature | Central Cloud | MEC / Edge |
Location | Central data center | Near network edge |
Processing | Centralized | Distributed |
User proximity | Usually farther | Usually closer |
Real-time workloads | Possible | Particularly suitable |
Backhaul | Potentially higher | Can be reduced |
Enterprise use | Broad | Location-sensitive workloads |
A practical deployment may use both.
For example, an AI application could perform real-time inference at the edge while storing historical data and performing large-scale analytics in a centralized cloud.
AI and Edge Computing
AI is becoming increasingly relevant to telecom.
Large amounts of data can be generated by:
Cameras
Sensors
Vehicles
Industrial machines
Mobile devices
Network infrastructure
Processing all this data centrally may not always be efficient.
Edge AI allows selected workloads to execute close to the data source.
Potential telecom applications include:
Network anomaly detection
Predictive maintenance
Intelligent traffic management
Resource optimization
Video analytics
Network security
Automated operations
The course's capstone also includes a 6G AI-powered resource allocation model, connecting telecom engineering with artificial intelligence and future network concepts.
5G Private Networks
Private 5G networks provide dedicated connectivity for organizations and specific locations.
Potential environments include:
Manufacturing plants
Ports
Airports
Warehouses
Mining
Universities
Research facilities
Large enterprise campuses
Private 5G can combine:
RAN + 5G Core + Edge + Cloud + Security + Enterprise Applications
This makes private networks an excellent example of why telecom engineers increasingly need multidisciplinary skills.
