� 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.

NGN Monitoring System(NMS)



NGN Monitoring System(NMS)

NMS could be used as a part of OSS systems and take a

part in fault management and in performance

management systems

NMS could be control and compare different parameters of

protocols and interfaces operation in accordance with ITU-

T Recommendation M.3010

Implementation of NMS as OSS part (M.3060/Y.2401)



The main tasks of NMS

� to control and monitoring the stand alone elements of NGN

(NGN Technical means)

� to control and monitoring the elements implementing to NGN

SP network under payload

� to control and monitoring e2e call scenarios with control main

parameters which could be give information for QoS control

(delay, jitter and etc.)



� NMS is important and basic measurements instrument which must to be realized on the NGN service provider network

� NMS must to be used on the Model network in accordance with ITU-T Recommendation Q.3900 and is a basic and main system for NGN technical means testing

NMS functional architecture



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
