Cloud Native Mobile Core


Cloud Native Platform

Fully Automated Mobile Core

Cloud Hosted Mobile Control Plane

Self-Healing Network

Common platform services to support Docker lifecycle automation and common operational functions. Package VNFs as Docker containers for orchestration and automation.

Refactor and rebuild functions of StarOS as containerized microservices extending current UP/CP separation effort. Address next gen forwarder, state and protocol separation.

Automated instantiation and lifecycle management across a complete mobile core solution. Along with EPC and PCRF, include additional 3GPP functions for an E2E Mobile Core: NRF, NEF, AUSF/HSS, UDM, etc.

Deliver an E2E disaggregated mobile core solution in a public cloud with user plane on premise. Fully automated lifecycle integration of local UP and hosted CP in separate domains.

Leverage analytics to combine artificial intelligence & deep learning and dynamic network to create

knowledge network

• State separationSession state is deployed in separate containers enabling simplified scalability and availability of application services

• Lightweight FootprintContainer startup times in seconds as opposed to minutes for VMs. Deploying patches and upgrades target only updated containers.

• Service Discovery As containers become available they are dynamically discovered and added to runtime.As containers fail or are removed, dependent containers are made aware.

• Elastic Scalability and High AvailabilityDynamic scheduling of containers enables for simplified scale up/down of each individual service.Lightweight stateless containers can be more quickly detected and recovered.

• Highly PortableContainer technology encapsulates the program and its dependencies to enable portability across bare metal and virtual machines running on public and private clouds.

Cloud Native Benefits

Cloud Native 3-tier VNF Architecture

Protocol Load Balancer Services

Application Services

State Management Services

VNF Service • Load Balance requests to app containers

• Protocol termination, e.g., Diameter, GTP, HTTP2

• Dynamic Discovery of application containers

• Stateless services

• Core application/business logic• Varying degrees of microservice

granularity depends on the app• Native scale out and upgrade• Stateless services

• State separation layer• Supports different data storage

technologies – in memory caches to full fledge DBs

• Scale out technologies
