Automated software upgrade for reconfigurable mobile device

Due to rapid advancement of the mobile communication technologies and the existence of multi-standards, the demands for managing mobile device effectively to fulfill various functionalities are on the rise. With the development of firmware over-the-air (FOTA) technology, the reconfigurable feature of mobile device provided by Software Defined Radio (SDR) technology offers a new way to realize the multi-functionalities of mobile devices. Therefore, based on the reconfigurable feature provided by SDR devices and the FOTA technology standardized by Open Mobile Alliance Device Management (OMA DM) standard, in this thesis, a framework of Modulation Module Update (MMU) is proposed for upgrading the modulation module on the mobile device over-the-air. As the modulation module is a vital module for radio devices, the upgrade or reconfiguration of modulation module can be extremely helpful for the realization of multi-functionalities. Therefore, in this thesis, the management object for updating modulation module are defined based on OMA DM standard, and three operation phases are defined in this framework as well. Compared with the original framework provide by OMA DM standard, the MMU framework is significantly improved from both the logical structure design aspect and the operation mechanism design aspect. The download operation of the firmware upgrade is optimized by the download mechanism proposed in this thesis, which is an over-the-air (OTA) software download mechanism combining the centralized download method and the decentralized download method for different circumstances. An important module named Central Information Controller (CIC) is also proposed to realize the control of the decentralized download method. The implementation of the MMU is achieved in this thesis as well. The server side and the client side of the framework as well as the CIC are simulated to test and verify the framework we proposed for the modulation module OTA upgrade.
