DingLi’s Intelligent Autonomous Solution Time to explore the real benefits!

INTRODUCTION (reference customers) Two of China’s major mobile network operator Mobile network location: Anhui province Area around 139,600km² 60.3 million population Mobile network operator 1: approx. 30 million subscribers Mobile network operator 2: approx. 9 million subscribers Migrated from traditional network tuning and optimization practice to Intelligent Autonomous solution from DingLi Previous operational processes (e.g. mobile network DL data optimization) in summary: Dedicated outdoor and indoor network test and optimization team Network optimization activities are mostly based upon received customer complaints Collected data is post processed and analysed at the back office by a dedicated team Provide network tuning and optimization solution/recommendations Manual performance verification performed by dedicated team Repeat step 3 to 5 if necessary

CHALLENGES Disadvantages of previous network tuning and optimization process Reactive effort instead of continuously verifying network performance is at optimal level Requires a big operation team to troubleshoot and optimize large coverage area Most processes are still labour intensive Very time consuming High on OPEX Inefficient in dealing with urgent customer complaints and meeting customer satisfaction KPIs

RECOMMENDED SOLUTIONS Pilot Fleet Unify Centralized remote probe administration and configuration Remote data upload, processing, analysis, storage, intelligent analysis, solution recommendation Real-time monitoring of all remote measurement probes in the field Pilot RCU 24/7 unattended remote network and services test measurement probe Multi-technology network quality and services performance verification Deploy Pilot Fleet Unify “Intelligent Workorder” Automated, remote and unattended mobile network testing, data collection and network verification Intelligent root cause analysis and “workorder” recommendation Process repetition to ensure a continuously optimized network performance
