1 International Telecommunication Union NGN Standards overview and Workshop Objective Chae Sub Lee (Chairman of WP2/13, ETRI, Korea)
2 Contents 1. Why need NGN? 2. NGN and its Standards 3. Objectives of today
3 1. Why need NGN? Success, Problems or Dilemmas? Service based Infrastructure On line Life Telecom Business User needs Future requirements others Monopolized Communication era Off line Life Information Society (21C) Competitive ICT era Network based Infrastructure
4 1. Why need NGN? Telecom Market Today *Source : Mobility and Fixed Mobile Convergence, John Visser, Nortel, ITU-T/ATIS NGN Workshop, Las Vegas, USA, March.2006
5 1. Why need NGN? What is keeping SP CEOs awake at night? o Revenue is saturated or declining for most core products o Competition is increasing in all markets o Google, Skype et al are creating a new kind of competitive landscape o Costs are too high o We need a solution NOW *Source : NGN: an answer to all end users problems?, Chris Lewis, NGN Industry Event, London, UK
6 1. Why need NGN? But even Mobile Business ARPU of SK Telecom in Korea $ Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec ARPU Wireless Internet Source:
7 1. Why need NGN? 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
8 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 customer churn Higher ARPU Ability to expand into new market segments Don't know/not sure Percentage of respondents *Source : NGN, IMS and FMC, Graham Finie, NGN Industry Event, London, UK
9 1. Why need NGN? Everybody needs next, so NGN N G N Integrated Engineering Intelligent Office Moves, adds and changes *Source : NGN: an answer to all end users problems?, Chris Lewis, NGN Industry Event, London, UK Mobile Workers Teleworking
10 2. NGN and its Standards NGN in 4 words by Fixed by Mobile by Wireless NGN = Broadband Managed IP Network for Services for Businesses for Players for Users
11 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
12 2. NGN and its Standards NGN is not Next Generation Internet the the IMS IMS based network only only for for a Fixed nor nor a Mobile network any any more best best duties any any more closed public network only only for for usage awareness but Next Generation Public Telecommunication Net. Net. IMS IMS is is a core core part part of of NGN NGN Converged capabilities btw. Fixed-Mobile (FMC) guaranteed duties fully fully open I/F I/F in in accesscore and and service-transport support various businesses core
13 2. NGN and its Standards Deliverables from FGNGN NGN Definition and Features (ITU-T Rec. Y.2001, 2011) Scope + Service Req. + Capa. (4) Quality of Service aspects (9) Control of QoS (1) Resource Adm./Cont. aspects (1) Security aspects (2) Migration aspects (3) General Funct. Archit. (7) Future Packet Based Networks (4)
14 2. NGN and its Standards Impacts of NGN Standards Business/Application oriented projects Limited Services FMC RFID IPTV Others BE IP Limited BB N G N Managed IP Converged Broadband Simple linkage btw layers Simple business relationships Simple players Simple linkage btw layers with dynamics Diverse and Flexible business relationships Diverse business models and players
15 3. Objectives of today Overall NGN Architecture Applications ANI Application Support Functions & Service Support Functions Control Media Management Management Functions End-User Functions Service User Profiles Transport User Profiles Service stratum Service Control Functions Requirements Network Attachment Control Functions Resource and Admission Control Functions Transport Control Functions Interactions Other Networks UNI Transport Functions Transport stratum NNI
