Evolution from 4G to 5G

Evolution from 4G to 5G

  • ASTRI has developed EPC and virtual EPC since 2012. With the 3GPP release 15 standard already announced, there is a new 5G core network architecture. ASTRI continues to develop 5G core which enables direct and standalone (SA) connection with 5G NR (New Radio) and unlocks the end-to-end benefits of 5G by providing new capabilities, such as:

    Service Based Architecture (SBA): With SBA, control plane network functions are fine grained and loosely coupled.  Network functions are interfaced using web-based APIs; enabling service composition becomes easier.

    Control and User Plane Separation (CUPS): The separation of Control Plane (CP) and User Plane (UP) provides topology flexibility and independent capacity scaling.

    Network Slicing: Multiple applications can be deployed in separated logical networks (network slices) in a shared 5G infrastructure.

    Edge Computing: User Plane Function (UPF) can be distributed and deployed close to the users, enabling ultra-low latency and time-sensitive usage scenarios.

    ASTRI’s 5G Core Network

    Scalable Throughput to 200Gbps

    ASTRI’s 5G Core User Plane Function (UPF) delivers high network throughput.  ASTRI’s UPF can leverage the Dynamic Device Personalisation (DDP) capability on Intel XXV710 to achieve fine grade load balancing.  On a single Intel x86 server, the UPF throughput can scale from 40Gbps to over 200Gbps.

    Open API

    ASTRI’s 5G Core supports Open API for 5G applications to interact with the core network, e.g. subscribe to mobility events, Industrial IoT.

    Orchestration & Network Slicing

    ASTRI’s 5G Core Network orchestrator enables end-to-end virtualised deployment of 5G core network.  The orchestrator supports network slicing management.

    Cloud Native 5G Core

    ASTRI 5G Core Network supports deployments on elastic cloud infrastructure:

    • Container-based deployment
    • Microservice-based network functions and platform services
    • Cloud-based load balancing/clustering
    • Centralised cloud scale management – logs, alerts and metrics
    • Stateless network functions
