With the acceleration of 5G networks deployment and rapid growth of traffic, operators face the challenges of huge and complex network systems and difficulties in network management and service operation that are beyond the manual processing capability.
ZTE AI insight value operation (AIVO) solution (Fig. 1) aims at solving the pain points of operators. Based on a unified platform integrating big data and AI, the solution provides the digital operation sand table and support system to help operators improve integrated management of network planning, construction, O&M optimization and service development, and each domain's efficiency.
On the one hand, the solution proactively discovers operational problems through a predictable network, service, and user insight, and rapidly achieves end-to-end optimization. On the other hand, driven by data, it achieves interconnection of planning, construction, O&M optimization and service development, integrates the operators' production requirements into the big data analysis platform, and implements intelligent, closed-up full-process service processing with AI enablement.
The AIVO solution provides intelligent insight into telecom data. It uses big data and AI to integrate full data of all domains, and is capable of collecting 100GE big data, identifying over 10,000 services and assigning over 9,000 tags to user profiles across multiple industries. It provides three-dimensional insight into network, services and users in terms of quality, value and development.
At the network level, the solution can automatically identify the poor quality NEs, poor quality cells and value areas, and intelligently predict the network capacity and performance. At the service level, it can report the status of 2G/3G/4G voice service and various data services in real time, and provide insight into the quality of voice and video services through second-level slices. At the user level, it builds an intelligent perception evaluation system for each service of each user to accurately assess user experience and provides insight into behaviors and preferences of high-value customers based on user profiles to guide personalized smart marketing.
Two Types of Integration
Based on ZTE's intelligent big data platform, the AIVO solution achieves two key types of integration: the integration of big data and AI into an architecture to provide intelligent big data openness capability; and the integration of network O&M and service O&M to provide integrated, intelligent O&M capabilities.
Big Data + AI Integration
The solution builds an integrated system including a big data platform, an AI platform and NM to form a unified data lake and AI capability, and opens data and AI capabilities via OpenAPI to support fast customized development and provide intelligent application data service. It supports intelligent operation combining the homing and hosting modes. The homing mode carries out intelligent training and releases typical AI models to the model market through moving data into a data lake, unified data governance and modelling. In the hosting mode, the on-site system obtains a model from the model market, iteratively preforms optimization based on the existing network data, and realizes intelligent operation.
Network O&M and Service O&M Integration
The solution enables interconnected management of the NE layer, network and service management and control layer, and service operation layer through data connection and sharing. It offers the integrated O&M capability with "unified view, whole domain perception, intelligent closed loop and active O&M". On the one hand, it provides a real-time, customizable unified operation view to support operation decision-making. On the other hand, the system accurately predicts and locates faults by associating all domain perception data, and intelligently solves problems in a closed loop by connecting the alarm and work order systems, thus forming the active O&M capability.
Three Major Applications
Based on the big data analysis and AI enablement platform, the AIVO solution continuously creates value for operators through precise planning, intelligent optimization and O&M, and value operation.
Precise Planning and Construction
The solution adopts an accurate 5G planning scheme based on the existing 4G network, makes full use of the existing network and environment information, and outputs agilely the expansion construction scheme through such means as intelligent network prediction, scene-based site selection and value sorting. In actual projects, 50,000 cells can be planned in half a day. Site planning is simplified by 28% than the initial solution, and the coverage excellence rate can reach 95%.
Smart & Simple O&M and Optimization
The solution provides intelligent and automatic capability, and improves O&M and optimization efficiency in complicated networking. In the VoLTE project, the AIVO solution provides O&M guarantee for over 100 million VoLTE subscribers, and promotes the growth of millions of subscribers each month. In the BS energy-saving project, the AIVO solution is implemented in more than 10,000 cells. While keeping the network indexes stable, the intelligent power-saving application time of the BS is increased by 80% compared to the traditional manual power-saving time, and the power consumption is reduced by 10% to achieve the green operation.
By utilizing big data user profile technology and AI methods, the AIVO solution provides precise marketing, and support for payload improvement and user development. In practical projects, it can identify potential 5G customers, and implement precise service provisioning and package recommendation for 5G users. Through user migration, hot service and regional analysis, and precise marketing of low-traffic users, the solution helps the customer increase the payload by over 50% and increase the marketing subscription conversion rate by 30%.
The ZTE AIVO digital operation solution has been widely applied in over 30 networks around the world, and ZTE has carried out value operation exploration with more than 80 partners. With the deep integration of big data and AI into telecom network operation, the AIVO solution will continue to help operators improve their efficiency and support telecom operators' service innovation and revenue growth in the new 5G network era.
