Huawei Releases 4.5G Experience-driven Mobile Backhaul White Paper

[Shenzhen, China, July 11, 2016] Huawei released its 4.5G Experience-driven Mobile Backhaul White Paper at the 2016 Huawei User Group Meeting. The White Paper introduces the experience-driven 4.5G mobile backhaul architecture and proposes evolution solutions for various scenarios such as user experience, O&M, and other telecom operator concerns in the 4.5G era. This is the industry's first white paper to systematically explain the 4.5G mobile backhaul solution and instruct telecom operators how to quickly launch 4.5G services and achieve business success.

Compared to conventional voice services in the 3G era and video services in the 4G era, emerging data applications in the 4.5G era, especially HD videos, require higher bandwidth, lower latency and lower packet loss ratio to ensure a good user experience. Operator first priority is to build a 4.5G mobile backhaul network that enables experience awareness, fault demarcation, and service assurance to support the business development of all parties.

The White Paper adopts the U-vMOS (User, Unified, Ubiquitous-Mean Opinion Score for Video) system, to objectively measure and quantify video experience. Based on the U-vMOS scores, the solution for 4.5G mobile backhaul architecture is formulated to enable the optimal E2E experience, providing operators with quick network construction, throughput optimization, experience awareness, and fault locating capabilities. This solution effectively solves problems met by users in high-definition video playback, such as long loading time, pixilation, and frame freezing. It also eliminates user complaints about fault locating failures, providing users with enhanced service quality and experience.

The 4.5G mobile backhaul solution features agile deployment, large bandwidth, and experience-driven O&M. The innovative seamless MPLS+ networking solution is adopted to simplify network protocols and achieve agile deployment. With the MPLS+ solution, a network consisting of up to 100,000 nodes can be set up in a single domain and is able to establish X2 connections as required by base stations. To cope with frequent traffic bursts caused by videos, the 4.5G mobile backhaul solution provides 10 Gbit/s site access capability and large throughput. Services can be automatically switched to light-loaded links when congestion occurs, greatly reducing the E2E service delay. Experience-driven O&M detects customer KQIs and network KPIs (precision reaches 10-6) in real time to implement efficient fault demarcation and locating. User experience analysis changes from passive mode to active mode. Even minor changes on the network can be detected to avoid partial congestion.

Huawei actively seeks joint innovations with industry-leading operators, aiming to provide users with the optimal experience and help operators achieve business success. To date, Huawei has deployed more than 190 mobile backhaul networks in over 100 countries, serving one third of global users.
