Introduction

• As mobile devices have many functions and provide
  the accessibility to the heterogeneous network,
  the end-users wish to use the more reliable and
  more quality services on their mobile devices
• the mobile device will have more failures because
  of its complexity
• The need on self-diagnostics of the mobile
  devices has been increasing

4
Problem Definition

• There is still little remote monitoring solution
  for diagnostics of mobile device failures
• Similar Related work
• general OS such as Window and UNIX
• Symbian OS

5
Goal

• Generic remote monitoring method to diagnose
  failures in mobile device based on OMA-DM
• Define generic management objects (MOs) for
  diagnostics of mobile device failures
• Design management operation
• Define device diagnostic functions and MOs for
  them
• Validation
• Development of remote monitoring system based on
  Mos
• Test on Battery Drain Problem
