What can be managed with OMA Device Management (OMA DM)?
Each node in the OMA DM device management tree can contain a value or may contain sub-nodes forming a tree. OMA DM has defined a number of mandatory and some optional standard management objects which expose common device attributes through a standard interface. Top-level management objects contain standardized information about the device, such as the manufacturer name and device model. Device-specific information may be placed in extension nodes allowing each vendor to expose additional information without breaking the standard. By manipulating the management objects, an OMA DM server can change any exposed device setting, such as the IP address of the GPRS gateway or IMAP server. Using the Firmware Update Management Object (FUMO), an OMA DM server can inspect the firmware version and currently installed updates as well as transfer and install additional firmware updates. The OMA DM protocol does not specify the type of the firmware update images and thus leaves enough room for diffe
