3 ITU-T Focus Group IMT-2020 Deliverables

Based on the above insights (but not limited to), following requirements can be suggested for the eNMS:

• Since the number of nodes is increasing and the moments of installing and discarding the device are
very frequent, the network management functions should be very scalable.
• The polling tasks for the devices to collect the real-time management information can give great
burden to them, shortening the survival time of the node and even harming the service experience.
• Most of the small IoT devices do not provide any network management protocols.
• The network management function should properly communicate with the sensor controller to
collect the information for each sensor under the controller, and sometimes even to send the
control command to the controller to actuate the sensors.
• The sensor controller should provide general management protocols, and be able to delegate the
management tasks for the sensors under its domain.
