At MWC 2019, Huawei launched the 5G-ready converged transport network solution. 
This solution will help build a transport network that supports all services, 
helping operators jump start 5G development through simplified 5G transport and 
fast deployment. So far, Huawei has won over 40 commercial 5G transport 
contracts.

GSMA predicts that by 2025, there will be 1.3 billion 5G users and 1.36 billion 
5G mobile devices around the world, with 40% 5G network coverage. To build 5G 
networks, transport networks should get prepared in advance. 5G networks have 
three major use cases, bringing 10x higher network bandwidth, 10x more 
complexity in network operations & maintenance (O&M), and 100x more 
connections. These are the core challenges that operators will face when 
building 5G transport networks of the future. During this process, operators 
will need to consider the future-proof evolution capabilities of their 
transport networks.

"Operators must systematically consider their business needs of the next decade 
when building 5G transport networks," said Jeffrey Gao, President of Huawei 
Router & Carrier Ethernet Product Line. "During this process, we believe 
operators will have to take into account three major standards: affordable 
bandwidth upgrade costs, 4G and 5G converged transport, and end-to-end 
automated O&M."

To meet operator needs, Huawei launched the 5G-ready converged transport 
network solution, enabling global operators to maximize their business value by 
offering three core capabilities.

The 5G-ready converged transport network solution was built upon the industry's 
first 50GE router and 5G microwave solution based on the four-level pulse 
amplitude modulation (PAM4). This results in 10 Gbps to sites and 30% lower 
total cost of operation (TCO). For fiber access scenarios, the router supports 
two-way single-fiber transmission, reducing cost per bit by 30% and fiber 
resources required by 50%. For scenarios without fiber access, Huawei's 5G 
microwave solution can deliver 10 Gbps bandwidth access over any frequency 
band. It also offers flexible channel expansion capabilities, so that only one 
site visit is needed for service provisioning, reducing operator TCO by 30%.

The 5G-ready converged transport network solution uses the industry's first 
commercially-ready SR and SRv6 solution, enabling smooth evolution from MPLS to 
SR and SRv6 protocols, with no interference between 4G and 5G services. 
Huawei's 5G transport solution supports both MPLS and SR protocols, so that 
operators can use the SR and SRv6 protocols for deploying end-to-end 5G 
services while simultaneously using the MPLS protocol for 4G services. This 
means new services can be deployed while ensuring the continuity of older 
services.

Built on the network processor (NP) programmable architecture, the SR and SRv6 
solution supports smooth evolution from MPLS to SR and then to SRv6 without any 
changes to the hardware.

The industry's first Network Cloud Engine (NCE) integrates network control, 
management, and analysis, allowing the 5G-ready converged transport network 
solution to support full-lifecycle automated O&M across the entire transport 
network. Huawei's NCE supports the unified control and management of 4G and 5G 
transport networks, and provides a machine-machine interface that is driven by 
models, instead of a human-machine interface. This reduces the time required 
for service provisioning from hours to minutes. And the telemetry and AI 
technologies mean it takes minutes, rather than hours, to complete fault 
demarcation.

The NCE also possesses big data analytics capabilities that enable visualized 
service level agreements (SLAs) and targeted transport network expansion and 
optimization.

"5G will meet the needs of both individuals and vertical industries, and 
support new services such as Cloud VR, private lines, and connected vehicles," 
said Jeffrey Gao. "Future 5G network architecture will be built upon data 
centers. The quality of various innovative services requires 5G networks to 
provide guaranteed SLAs. Therefore, upstream and downstream industry players 
must seize the opportunities presented by 5G development and build an 
All-in-One converged transport network."

"Huawei continues to work with industry partners and innovate in data 
communications and optical fiber to build non-blocking physical networks. 
Together, we will work to ensure high availability and non-blocking physical 
networks that support deterministic low latency, on-demand services, and zero 
touch O&M."

Huawei has remained at the top of the global mobile transport market for seven 
consecutive years, leading the development of the mobile transport industry. It 
has also helped leading global operators build over 40 5G transport networks. 
Huawei plays an active role in international standards organizations such as 
the Internet Engineering Task Force (IETF), ITU Telecommunication 
Standardization Sector (ITU-T), and European Telecommunications Standards 
Institute (ETSI). It is a key contributor to 50GE and SRv6, and is a leader of 
5G microwave and intelligent networks.
