The Research On Device Management Platform Based On OMA DM Standard

In order to meet the needs of the users, telecom operators have introduced a variety of mobile value-added services. Especially in the background that the 3G network has just been put into use, mobile value-added services will develop more rapidly. However, the development of mobile value-added services brings to the users a lot of troubles. For example, in order to use the business that telecom operators introduced, users must set device accordingly or install client software in the device. The possibility of device failure appearing increases. Device firmware will be gradually outdated, so that users could not use the new business.OMA international organization put forward the concept of device management and constituted OMA DM standard on the basis of the SyncML protocol in 2002, providing us with a solution to above problems from theoretical foundation. The device management platform which is researched in this dissertation is just based on the OMA DM standard. This platform realizes functions of firmware update, configuration management, information collection, remote diagnosis and lock&reset.Firstly, this dissertation describes in detail the device management service and extracts the business requirements. Based on analysis of business requirements, device management system is divided into three subsystems, namely, operational subsystem, business management subsystem and portal subsystem .Secondly, we research into the device management technology deeply, based on OMA DM standard. The solution of how to obtain device description information is introduced, which is based on OMA DM standard and UAProf (User Agent Profile) mechanism. Thirdly, we research into the software framework of device management platform deeply. The software framework of device management platform is introduced, which is based on MVC model and J2EE technology. This software framework separates the business logic level from the system, so that the coupling between the businesses is reduced, the reusability of the code is increased and the extensible of the system is enhanced.Finally, we design and implement the device management platform, and also analyse the performance of the device management platform.
