Assist Field Service

The Assist Field Service (AFS) solution provides clear insights of problem distribution within mobile networks and aids in applying improvements based on proven customer experiences, reducing operational costs associated with multiple site premises.

Field technicians may now be equipped by the Operator with an efficient tool to diagnose and support in the resolution of customer affecting network issues. AFS will diagnose and report detected quality issues (QoE) or Quality of Service (QoS) KPIs concerning the local radio conditions and network performance.

Aggregated results in different views, allows different support areas (Engineering, Operations, and Customer Operations) to effectively analyse the obtained Customer Experience data for faster problem solving and decision making in real-time.

Why do we need the Assist Field Service?

  • Reduce operational costs distributing the AFS App among technical field teams
  • Field teams behave as “customers” identifying trouble spots and taking proactive actions to resolve them
  • Significant economics in detecting, reporting and analysing of network quality issues based on digitalized work processes
  • Increased customer response efficiency at multiple levels
  • The operator can prevent churn through problem anticipation and network quality enhancement

Solution highlights

  • Assist Field Service solution, allows Operation Engineers to verify reported feedback solving issues and producing reliable indicators to steer network improvements
  • This solution is integrated into any operator android application and customized
  • Even in roaming, it is possible to analyse radio and network conditions, without incurring roaming traffic costs.
  • This solution is an integrated platform that consolidates the most relevant data in a very simple and effective way, allowing faster problem diagnosis and resolution, leading not only to improved customer support productivity but also to client satisfaction.
  • All measured results are collected on the server, stored in a central database and can be viewed in the integrated frontend, producing historical measurement data, including a powerful search tool to find and report data faster.
