Nokia AirGile cloud-native core
Core-native core network functions built and optimized for the cloud deliver service agility, performance, scale and flexible resiliency.
Disaggregated architecture with stateless and state-efficient designs, for both centralized and distributed deployments.
Using cloud-native design principles such as DevOps and micro-services where appropriate yields shorter innovation cycles to support enhanced mobile broadband, IoT/MTC and 5G.
1. Shared Data Layer As well as being a common store for all user and service data, the Shared Data Layer also acts as an open repository allowing third parties to develop new services and contribute new revenue streams.
2. Stateless VNF machines These are another key element, offering a radically simplified architecture and simplified operations with plug-and-play installation and a high degree of resilience.
3. Openness In the new world of the Cloud, openness is one of the defining characteristics. AirGile offers a programmable open ecosystem, allowing OTT services, open APIs and a modular open architecture.
4. Micro service architecture AirGile also supports a micro service architecture with small components that allow services to be adapted, developed, scaled up and managed much more quickly and readily.
5. Distributed and centralized core deployment A cloud-native architecture allows both distributed and centralized core deployment bringing huge benefits – 10 Gbps peak rates, 1 ms latency and 1000x traffic growth.
6. Web scale deployment offers automated life cycle management for software defined VNFs. Hardware and cloud infrastructure agnostic, it supports network slicing.
Cloud-native core components
1. Subscriber Data Management/Shared Data Layer
The cloud-native core network is shaping up with layered architecture in which not only are the user and control planes separated, but virtualized network functions (VNFs) become stateless and data-less. A Shared Data Layer (SDL) stores subscriber and session information, creating a very flexible network in which any VNF has access to all data whenever required and from any location.
The network also becomes more robust because in case of a VNF failure or SW upgrade, it is easy to switch in a replacement VNF that has instant access to the same data to provide continuity of service. This simplified arrangement not only enables easy and massive scaling, but it also reduces signaling traffic substantially.
2. Nokia IMS/VoLTE core builds a unified converged voice solution. It runs on a common cloud infrastructure and providing open APIs enabling operational automation and flexible support for new services and value added functions. Nokia IMS/CSCF and TAS programmability makes operator’s network an open ecosystem to enable new services, network function programmability and service experience.
An important aspect of Cloud-Native VNF is to enable stateless operation. Nokia IMS / VoLTE product architecture enables separation of session and state information to data later, supported by Shared Data Layer. This fundamental architectural change supports scalability on demand and easy lifecycle management at run-time.
The Nokia cloud-native IMS/VoLTE applications are decomposed into microservices, this means, tasks are broken down into separate services that are modular and can run in different locations.
3. Evolved Packet Core
The Nokia Cloud Mobility Manager provides the web-scale and state-efficient design needed to meet the growing control plane demands of broadband evolution, IoT/MTC, and the transition to 5G. It performs the MME and SGSN functions in 2G/3G/4G networks, and supports a range of IoT optimizations for cellular IoT networks.
The Nokia Cloud Mobile Gateway is designed and built on the principles of cloud networking and web scale performance, providing a wide variety of mobile gateway functions including the SGW, PGW/GGSN, HA, ePDG, TWAG, PCEF and enhanced TDF. Its high-performance, elastic, state-efficient design and distributed processing architecture provides the scalability and data forwarding capacity needed for the growth of mobile broadband and the delivery of new IoT/MTC services, and provides an evolutionary path to 5G next-gen core.
4. Dynamic Diameter Engine
Nokia offers a complete solution for Diameter signaling control with the Nokia Dynamic Diameter Engine (DDE), which handles relay, proxy, redirect and interworking functions in native, or virtual deployments, along with several key features to facilitate roll-out of Diameter in a network
5. Policy and Charging
The Nokia Smart Plan Suite (SPS) provides Policy Control (PCRF), Online Rating and Charging (OCS) and Customer Engagement functions that enable new monetization opportunities for service providers and a better experience for their customers.
6. Session Border Controller
The Nokia Session Border Controller cost-effectively controls, secures, and manages media and signalling streams for fixed and mobile services.
