Competition is increasing in all markets
Google, Skype et al are creating a new
kind of competitive landscape
Costs are too high
We need a solution NOW

ARPU Analysis
o Analysis means
• Subscribers saturated in Korea
• ARPU increases little and little slightly
• Voice revenue keeps stagnant
• Wireless data revenue has jumped three fold over
the past three years
• But ARPU doesn’t increase that much because of
price reduction

1. Why need NGN?
No clear reason, but want…..
What is the main benefit of FMC for telecom service
providers?
Lower capex or opex
Lower cus tom er churn
Higher ARPU

2. NGN and its Standards
Objective of ITU-T NGN
! Provide both Customer and Provider facilitated
provision to support services over wireline and
wireless broadband accesses
! Support the desire of customers to be able to access
their services from anywhere (inherent mobility)
! Facilitate to merge diverse network services – data
(web browsing), voice, telephony, multimedia and
emerging “popular” internet services such as Instant
Messaging and Presence and broadcast type services
! Support a flexible platform for service delivery
