The solution enables operators to efficiently optimize the network and evolve it on demand so as to build a top-quality bearer network.

Top-quality Bearer Network Delivers Business Success for Operators

In the LTE era, numerous services are available. Of all these services, data and video result in the sharpest increases in the need for the transmission capacity, which places harsh demands on mobile bearer network performance. As the customer base rapidly increases and the IP-based network develops, the mobile bearer network faces tremendous pressure and becomes a weak link in the entire mobile communications network. Performance of the mobile bearer network becomes the most important factor and a key point for building a top-quality LTE network.

When building a top-quality bearer network, operators need more rational solutions with lower risks and higher returns on investment (ROI). Operators need solutions that focus on the following three points:

1. Rational planning and effective investment:

Operator bearer networks are each unique; therefore unique optimization solutions are required. Operators require that service providers provide the most rational planning solution possible based on the full understanding of the live network. Objective metrics are the basis for management and improvement. Accurate metrics are the basis for building a top-quality bearer network. Operators need to build a 1:1 live network model to collect real-time quality and traffic data for the bearer network and to provide the best planning solution possible based on the live network baseline management. That is how they protect investment effectiveness.

2. Efficient operation support:

Besides providing optimal performance, a top-quality bearer network also needs to support efficient operations for agile business development. At present, operators require a unified ser vice quality and network traffic management platform based on different data sources so that they can perform consistent monitoring and maintenance. Based on E2E dynamic service quality monitoring data within an effective time period, root cause analysis is performed for operational problems caused by the bearer network. Solutions are provided for identified root causes to build a top-quality bearer network and produce efficient operations.

3. Optimization and restructuring efficiency:

Operators are also concerned with whether tools and platforms used during the verification of the optimization and restructuring solution can meet certain requirements, how similar the created network model is to the live network, and whether the algorithm for the software tool is accurate and efficient enough to effectively identify problems during network optimization and restructuring.

NetSense Service Solution

To build a top-quality bearer network, the management of the whole lifecycle is needed for the bearer network. A high-precision live network model needs to be built, and core requirements from service operations need to be learned for the bearer network. The network evolution is performed on demand to ensure efficient operations for operators.

To meet these requirements, Huawei provides the NetSense service solution to comprehensively manage quality and traffic for the bearer network and enable the on-demand network evolution so as to build a top-quality bearer network that supports efficient service operations. The NetSense service solution leverages an industry leading series of network test probes and service quality and traffic management processes to achieve full network quality management on a 24/7 basis. Performance capacity analysis is performed down to the second to support precise capacity expansion. An index system and a criteria library are created based on operator scenarios and applications. A customized, professional solution is provided for customers, covering network audit, planning, design, implementation, monitoring, optimization, and evolution. This enables operators to build top-quality bearer networks that are oriented towards fine-grained operations.

> Dynamic evaluation-based precise network modeling

Huawei NetSense solution leverages the most comprehensive industrial bearer network data available to build a precise network model. Based on an understanding of operators’ live networks and services, monitoring thresholds and the index system are designed to dynamically evaluate data from the live network and create a precise model. First, active and passive and in-built and external probes, atom meters, and mobile APPs are used to obtain multi-dimensional data on the network. Multi-vendor networking is supported and a precise network model is created based on the quality and traffic data of the whole network. This enables the index system of the bearer network to comprehensively measure the live network on a 24/7 basis. Then, the monitoring platform is used to analyze and diagnose real-time data from the live network. Data comparison and analysis are consolidated with the resource management system to automatically display quality and traffic data hop by hop in the system and to provide peak traffic data down to the millisecond. This helps to instantaneously analyze the impact that the peak traffic has on the device memory, learn the service traffic change status for each base station, and monitor the changes and trends in quality and traffic for the bearer network at any given moment. 

The NetSense service solution also performs static and dynamic evaluation on the capacity, service path, and LTE base station access capability for the bearer network. Based on industrial criteria and expertise, evaluation results are used to design the network evaluation index system for operators to comprehensively evaluate the quali ty of the bearer network.

> Operator data-based optimization and adjustments

Huawei NetSense solution helps to learn of changes in traffic and in network service performance to locate faults down to the second between the bearer network and surrounding systems, restore the fault path in one-click mode, and provide detailed information for each hop based on the fault path (including KPI data for the network performance and traffic). This allows for rapid fault location and accountability and great improvements in operational efficiency. In contrast with the traditional network management O&M solutions, Huawei NetSense solution provides KQI data based on the actual service flow and KPI data based on the actual service packet test to support the association analysis between KQIs and KPIs. Based on a set period of operations, performance bottlenecks can be effectively identified and analyzed.

During the operation maintenance phase, Huawei NetSense solution uses the index system to provide network capacity and network bottleneck forecasts based on service trends. Based on live network bottleneck and trend analysis, Huawei NetSense solution provides optimization and restructuring services for the bearer network and performs whole-process monitoring for the service bearer quality during the restructuring process, so as to ensure that the service quality improves greatly after the network optimization. Before new services run on the bearer network, Huawei NetSense solution performs a simulation of service bearing capability. This helps to identify the upper limits of the bearer network, improve operational efficiency, and support rapid provisioning for new services.

> Agile evolution on demand

During the service development phase, Huawei NetSense solution supports agile, efficient evolution on demand. The bearer network can respond to sharp service increases in a timely manner and maintain the best bearer network performance possible at all t imes. Huawei NetSense solution automatically maps dynamic evaluation data to Huawei’s self-developed protocols and the traffic simulation platform (IPCrystal) and performs the big network simulation based on a precise 1:1 data model of the live network and precise capacity and bottleneck forecasts. The best network evolution strategy and solution are efficiently provided. The on-demand integrated evolution mode, agile planning, and corresponding ROI analysis help operators select the best evolution solution, improve future network scalability, and avoid large investment in the initial phases. 

Furthermore, Huawei NetSense service solution delivers a rich network migration and restructuring experience. Based on Huawei Global Network Evolution & Experience Center (GNEEC), the solution provides a network environment based on a simulated live network to verify the evolution of the live network to the target network, and it generates the best fault location process, baseline library, and management platform based on the operator’s environment.

Since being released in October 2014, the NetSense service solution has successfully served China Mobile and China Unicom and has been put into use in the pilot for Malaysia Celcom, Belgium Mobistart, and France Bouygues to monitor and optimize the network. The solution helps operators build the best top-quality bearer network possible, improve the network performance and operations efficiency, and achieve business success.
