Which network functions do 5G core solutions include?

5G core solutions include key core network functions that facilitate a smooth transition to 5G. This includes Subscriber Data Management (SDM), Authentication Function (AUSF) performs authentication, Unified (4G+5G) Data Management (UDM) + Home Subscriber Server (HSS), Unified Data Repository (UDR), Unstructured Data Storage Function (UDSF), Policy Control Function (PCF) and Policy Control Rules Function (PCRF), Charging Function (CHF) + Online Charging System (OCS), UDR Agent Portal, Element Management System (EMS), Enterprise Self-Service Portal (ESS), and Network Exposure Function (NEF). Together, these 5G core network functions (NFs) authenticate and authorize access to services in both 4G and 5G mobile networks, support 4G and 5G subscriptions, enable convergent charging, monitor system health and performance, provide a self-care portal for enterprise customers for private 5G deployments, and more.

What are the benefits of 5G service-based architecture?

5G upgrades the core network to service-based architecture (SBA). In contrast to traditional legacy network architectures, SBA relies on cloud or virtual network functions (VNFs), enabling virtualization and network slicing. A significant benefit is that it decouples NFs and improves system modularity; NFs are virtualized and communicate with each other using a common communication protocol. SBA simplifies operations using APIs, enables seamless integration of third-party applications with the core network, facilitates enhanced security, and more.

Subscriber Data Management (SDM)

Alepo’s SDM module, part of Alepo’s 5G Solutions, comes with AUSF, UDM+HSS to carry out authentication and authorization in 5G network solutions as well as 4G networks. Includes a common and highly scalable Unified Data Repository (UDR) that holds SIM identities, subscription profiles, policy data, application data, and session contexts. It also includes the Unstructured Data Storage Network Function (UDSF) that maintains application states and contexts for different core network functions.

Converged Policy Control

Includes PCF and PCRF with a unified policy rule framework for data, voice, and application. Manages policies for 4G and 5G networks. Supports usage monitoring and integrates with the charging systems. Its business user-friendly GUI interface reduces time-to-market for advanced policy use cases.

Converged Charging

For voice, data, content, VAS, and IoT services across all access networks. Includes CHF and OCS; handles online and offline charging with the standards-based interfaces towards core network functions. Coupled with Alepo’s Digital BSS, it offers complete billing and charging for retail and wholesale business cases.

Web-Based Management Portals

  • UDR agent portal: for service configurations, storing and managing subscriptions, policy data, and SIM identities.
  • EMS portal: to configure and provision various network function profiles and services.
  • Enterprise self-service portal: allows enterprises to efficiently manage their devices and connectivity for private 5G use cases.

Cloud-Based Microservice Architecture

Cloud- and PaaS-agnostic; supports public, private, and hybrid deployment options. Supports containerized and NFV-based deployment.

Seamless Transition

Alepo’s core network solution + Digital BSS together support the unified management of 4G (EPC, IMS), C-IoT, and non-3GPP networks (such as WiFi). Among the handful of 5G core vendors providing end-to-end solutions, Alepo’s vast experience in digital transformation of telecom businesses helps ensure service providers can evolve their operations, upgrade to 5G without disruption, and shift to a fully virtualized service-based environment.

4G mobile operators with 5G core networks can deploy 5G radio protocols while leveraging the existing 4G infrastructure. Alepo’s 4G core functions allow operators to support mixed radio connectivity, enabling them to gradually roll out coverage and services to their customers.

4G + 1

Alepo also extends support to operators not yet ready to move to 5G. We bridge the gap by creating a modern omnichannel experience for subscribers, incorporating WiFi offload into the operator’s network and supporting unique enterprise IoT offerings on their existing network.

Deploy in the Public Cloud

5G core deployed in the public cloud is beneficial for CSPs of all sizes. It helps to rapidly bring 5G capabilities to market and will scale with the demand of network growth as more devices come online. A 5G core network can be deployed in hours versus months of shipping servers and setting up data centers.

Real-world applications are already promising, particularly in the era of streaming content. At the Olympic Games, a 5G core in the public cloud was proven successful to help distribute visual content swiftly and securely. Venues were outfitted with 5G base stations and photographers could upload high volumes of photos, videos, and other data to media agencies in the main press center, improving their coverage and overall viewing experience. As more use cases are tested and deployed, the scope for operators continues to grow.

Deploying 5GC in the public cloud provides a host of business benefits:

  • Save the CAPEX that physical infrastructure would require
  • Reduce OPEX by eliminating data center and IT maintenance
  • Easily scale for dynamic demand during seasonal or one-time events
  • Ensure swift time-to-market, streamline operations, and gain built-in services through partnerships with large-scale cloud providers like AWS, Azure, Google
  • Cater to enterprise or private 5G customers for applications like Industry 4.0, large-scale events like sports, conferences, exhibitions, and more
