At the recent 5G World Summit 2016, Huawei and Deutsche
Telekom were jointly awarded Most Notable Partnership Between an Operator and
Solutions Provider for 5G Trials and Development for their continuous
innovations and close cooperation in the 5G field.
A key focus in the 5G era is the optimization of network
architecture to meet diverse requirements for a variety of applications.
Because the optimization and evolution of the 5G core network is critical,
research in this area is of the utmost importance. As such, Huawei and Deutsche
Telekom have been in continuous collaboration to help develop the 5G core
network innovation. To showcase their joint efforts, the two parties performed
an end-to-end network slice demonstration based on a 5G core network at the
2016 Mobile World Congress.
Which aspects of the Huawei 5G core network helped win
favor with Deutsche Telekom and receive industry-wide recognition?
Innovative Comprehensive Cloud
Transformation
At the Global Analyst Conference held in April this year,
Huawei put forwarded three core features of Comprehensive Cloud Transformation,
on which the Huawei 5G core network design draws:
l Pooling all hardware resources, including network and IT
devices. Pooling transforms the traditional chimney-type architecture in which
a single application requires a piece of hardware, thereby maximizing resource
sharing.
l Fully distributed software architecture, a best practice
from Internet companies. Full distribution is a basic condition for
implementing large-scale systems. Only distributed systems can provide flexible
capabilities and implement flexible troubleshooting and resource scheduling.
l Automatic service deployment, resource scheduling, and
troubleshooting, which do not require any manual intervention.
Key Industry-leading Technologies
During 5G core network construction and reconstruction,
Huawei introduced key technologies such as NFV, SDN, Cloud, MEC, and SOA. The
decoupling of software and hardware enables multiple logical networks to be
established on the unified hardware infrastructure. The separation between user
and control planes allows for flexible deployment of logical functions.
Data-driven and open networks implement quick service provisioning and
real-time closed-loop optimization. Modular network capabilities and
atomic-level capability orchestration achieve automatic slicing for multiple
services.
Clear and Open Evolution Path
5G
core network evolution is carried out in two phases. In the first phase, NFV,
SDN, and Cloud are introduced to decouple software from hardware at the network
element (NE) level. This phase implements elastic resources and flexible services,
laying a foundation for further NE decomposition and capability reconstruction.
In the second phase, existing NEs are
decomposed and their capacities are reconstructed. For example, the MME, P-GW,
S-GW, IMS, and PCRF are decomposed into modules that provide authentication,
control, service, and management. Atomic-level capability orchestration
provides support for future service innovation and operation efficiency
improvement.
Huawei,
together with other leading operators, including Deutsche Telekom and China
Mobile, has helmed strategic 5G core network innovations. Huawei will continue
to cooperate with industry partners to create a 5G ecosystem and promote
development of the 5G industry.
