Introduction
NGN is a perspective evolutionary direction in public
telecommunication networks
All stages of NGN evolution could be divided on networks
which realizing by PES architecture with co working two
domain CS and PS networks and networks which architecture
based on IMS platform with the wide range of services and
different types of content
Independent of existing stage of networks evolution network
provider have to be realized on the network monitoring
system which could be allow to control quality of network
operation and prevent the fault situations.

Common measured values by NMS
According with ITU-T Recommendation Q.752, the following categories as
regards the measured values should be defined in the NMS based on PES and
IMS solutions:
•fault (F). Measurement for reporting processes and detecting problems, as well
as for finding out some abnormal situations in the SS7, SIP and H.248 signaling
networks, and for NGN hardware, involving its reconfiguring and restarting
procedures
•quality (Q). Measurement for service level parameters intended for different
traffic types involving voice and video ones under different services; for
reporting processes; for assuming measures in providing the service level
guaranteed, as well as for developing an operator’s policy and strategy in the
field of providing a certain service level. It should be also used to have the SLA
and/or SLS performed and relevant reports drawn up;

• traffic(T). Measurement for real time traffic parameters based on the
IP flows information for the purpose of identifying any unwanted and
unauthorized traffic; studying any inside and outside impacts on
network security; finding out any network abnormal events; defining
when requesting the user-to-user, user-to-network, network-to-user
interaction parameters; studying traffic changes trends; and conducting
preventing management
• accounting (A). Measurement for providing accounting and estimation
data reliability by comparing
• network administration and planning (N). Measurement for SS7 and
NGN networks administration including the SIP and H.248 signaling
systems; making decisions on networks development, further network
planning; optimizing network infrastructure enhancement investment;
planning applications and services; preparing traffic data to have
network further designed
• near-real-time measurements (R). Measurement for finding any faults
out in the network . It shall be considered supplementary one to the
abovementioned measurements

Conclusions
1. NMS is important measurement instrument which
could be used on all NGN evolution stages from PES
to IMS architecture
2. NMS have to allow tests NGN functions and e2e call
scenarios
3. NMS have to be used on the networks environment
under payload
4. NMS is common measurement system which could
be used on the Model Networks for NGN TM testing
