5.    The Device sends a confirmation back to the Device Management System.

6    Alternative Flow 1
1.    The device initiates a session with the Device Management System to request software component update.
2.    The Device Management System has detailed information of the software component available in the device, e.g. whether each software component has been installed/removed, what version the software component is, whether updates should be done promptly or later on.
3.    The Device Management System will selectively issue a request to the Device that has outdated software component version.

7    Alternative Flow II
