Need for NGN
Legacy network contributing to high OPEX/CAPEX
Customer Churn: LL to Mobile, Mobile substitution
Inherent TDM Limitation:
Delay in the roll out of service
Vanilla offerings. No seamless experience
BB penetration still Low
Entire world is moving to convergence
Customer wants flexibility of service
They do not want ‘Customer Device’ to be constraint
Be it may be LL phone, Mobile handset, PC or even TV set, Subscriber wants immediate service at any time at any place irrespective of the access technology being used ie., LL, 2G, 3G, PON, WiFi, WiMax, CDMA
Hence Convergence lead to increase ARPU
Demystifying Facts About NGN
Anything which is IP / Ethernet is NGN
The thread of NGN encompasses all business units and is not at all confined to a particular unit such as CFA or CM or Enterprise
NGN is long term object
NGN is a framework which facilitates 3C’s and 4A’s
The Guiding Principle
Sam Pitroda Committee Recommendation:
–“Invest in building a financially remunerative next generation end-to-end national IP network of the future to handle ever increasing internet and data traffic”
Current Generation Network(PSTN)
Level-I TAXs at 21 locations (LDCAs)
Level-II TAXs at 301 locations (LDCAs). Total No. of LDCCs - 322
Tandem / Transit Switches at Big Cities / SDCC locations (2325 locations)
Total No. of SDCCs 2647
Switches based on the principle of Circuit Switching
What is Existing Network?
It has evolved over a period of last 100 years.
It is mainly optimized for “VOICE” and not for data.
It uses “circuit Switching” which is highly reliable.
