ZTE launches integrated 2/3/4/5G common core

ZTE has launched its 2/3/4/5G fully-integrated Common Core solution at Mobile World Congress 2018 in Barcelona.

Based on the 3GPP R15 service-based architecture (SBA), it integrates all kinds of accessing modes including fixed-mobile convergence (FMC) in the layer of network functions (NF) and network services (NS).

ZTE Common Core consists of network function services defined by 3GPP specifications and public network function services. All the services address the requests of being self-contained, reusable and self-managed. ZTE Common Core provides services through HTTP/2+JSON interface. Distributed media planes support flexible deployment and high-performance forwarding as well as interwork with the control plane through the standard CUPS (PFCP) interface protocol.

ZTE Common Core, based on the cloud native concept, uses open microservice components, a carrier-grade visual DevOps tool and lightweight container technology, to equip network slices and network functions with on-demand orchestration, rapid deployment, flexible elasticity and high reliability. On the basis of full virtualization, it achieves the decoupling of an underlying cloud platform and the decoupling of software and hardware, and it leverages software and hardware acceleration technologies to meet the high speed, low latency, high reliability and other requirements of 5G application scenarios.

In the Phase I and Phase II 5G Core tests of IMT-2020 (5G) technology research and development and the 5G tests with the world's leading multinational operators, ZTE's 5G core network passed all the comprehensive testing and validation with its service-based architecture, network slicing, 5G service process, edge computing and other key technologies and was highly recognized by the IMT-2020 (5G) Promotion Group.

Compared with providing 5G access by upgrading 4G EPC, the 2/3/4/5G fully-integrated Common Core solution adopts the 3GPP standard SBA to provide users with better end-to-end service experiences and to provide operators with finer QoS control, more flexible deployment and standardized service interfaces to boost service innovation quickly. In addition, the Common Core solution allows operators to avoid multiple upgrades of wireless and core networks, which will greatly reduce operators' TCO (total cost of ownership).

As the world's leading provider of integrated communications solutions, adhering to the strategy of "Leading 5G Innovations", ZTE is committed to providing quality services for customers worldwide. The introduction of the fully-integrated Common Core solution marks a solid step for ZTE towards the industrialization of the 5G core network, laying the foundation for the commercialization and evolution of the 5G core network.

The benefits of replacing plain old paper with e-paper displays in automotive assembly plants
Efficiency is at the heart of automation, and that is nowhere more apparent than in the manufacture of automobiles. The Ford Motor Company is widely credited with inventing the moving assembly line, but the concept of moving the assembly, rather than the worker, dates back centuries.
