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.
