OMA DM Based Remote Software Debugging of Mobile Devices

摘要

The mobile devices have gained much functionality and intelligence with the growth of network technologies, the abundance of network resources, and the increase of various services. At the same time they are also becoming complicated and related problems to services and resources of mobile devices frequently occur. Since it is not easy for the manufacturers to completely remove the software errors of the mobile devices before they sell them, the users face inconvenience caused by them and the credibility of the manufacturers also decreases. So far, no definitive method has been given to debug software errors of the sold mobile devices. In this paper, we propose a debugging method to find and correct the software errors of the sold mobile devices based on the Open Mobile Alliance (OMA) Device Management (DM) standard. We define the managed objects (Mos) for composing the execution image and design the management operations for collecting Mos at the central server. We present a system that we have developed based on the Mos and the management operations. We also present how to debug software errors with the execution image and JTAG debugger.
