6                                     Unleashing the potential of the Internet of Things

            The supporting functions group, across the libraries layer and application framework layer of the
            Android OS, provides functionalities including DM and discovery, connection management, mobility
            management, data processing and data delivery. This functions group includes at least the following
            functions.
            –       A DM agent, which supports local or remote IoT device management applications to manage
                    the IoT devices exposed by the SPSN.
            –       Device  discovery,  which  discovers  the  IoT  devices  in  an  end  user  network  actively  and
                    processes active connection requests from the IoT devices.
            –       Connection  management,  which  establishes  and  manages  the  connections,  including  the
                    connections between IoT devices and the SPSN, and the connections between the SPSN and
                    IoT applications and service.
            –       Authentication management, which manages the mobility of the SPSN. When the SPSN joins
                    or leaves an end user network the SPSN manages the authentications and authorities to IoT
                    devices and end user networks.
            –       Data processing, which collects and processes IoT data from IoT devices locally.
            –       Data delivery, which delivers IoT data (including locally processed IoT data) to other entities
                    in communication networks or back to IoT devices.
            –       Application interface, which provides an abstract interface to support local and remote IoT
                    applications and services to access the IoT devices exposed by the SPSN, with standard and
                    uniform logical methods (e.g., web-based interfaces).

            The  local  or  remote  IoT  applications  and  service  use  the  application  interfaces  and  adaptation
            interfaces mentioned above to discover, access and manage IoT devices in the end user network.
            The security and management functions group, cooperating closely with all the layers of the Android
            OS, provides capabilities for supporting security of data and communications.
