Challenging Issues in Diagnostics and Monitoring of Mobile Devices

This presentation delves into the current challenges in diagnostics and monitoring mobile devices, focusing on the role of the Open Mobile Alliance (OMA). We explore OMA's history, its efforts to develop open standards for mobile services, and how these standards facilitate interoperability among various stakeholders in the industry. Key topics include device management (DM) diagnostics, monitoring techniques, fault detection, and inquiries into enhancing network performance. Join us for an insightful Q&A session to discuss these critical issues further.
