Figure 19 – Standardized network management system

In order to build up a standardized network management system, it is necessary to introduce eNMS
accommodating both fixed and mobile network, as shown in Figure 20. Support of legacy network equipment
using IWF (Interworking Functions) should be developed with relevant management object. Fault reporting
from lower layer network element to higher layer should be supported as well.

Figure 20 – Integrated Network Management Scenario

Instead of creating a separate network management system just for IMT-2020, eNMS can fully host both
legacy network equipment as well as new IMT-2020 network functions. All components of the network are
supported by eNMS including different RATs and the fixed network. Operators can have common
management viewpoint regardless of connection type. By deploying eNMS, network operation complexity is
simplified. eNMS is fully aware of all network equipment status such that it can optimize network functions
without management signaling burden. This results in cost saving. Therefore, eNS can save OPEX/CAPEX of
network operators.
