Background

A consultation process was initiated on NGN in Jan 2006 to deliberate on various issues.

Based on the feedback of stakeholders and deliberation on issues, TRAI issued certain recommendations in March 2006.

One of the decisions was regarding setting up of a committee named NGN-eCO

CN Division, TRAI 3

TRAI Decision no 6.4

“….. There is a need for setting up joint consultative

committee under the aegis of regulator involving

industry to deliberate upon the various issues related to

interconnection, QoS, Awareness building and

migration time table for NGN. For this purpose, it is

decided that An expert committee named NGN eCO will be

constituted by TRAI co-opting experts from DOT,

TEC, C-DOT, service providers, venders and

Academicians.

CN Division, TRAI 4

TRAI Decision no 6.4

This committee will handle at least the following

issues

NGN awareness building program

Time table for NGN migration in the country

Back ground paper to be used for consultation on

interconnection and QoS issues by TRAI.

CN Division, TRAI 5

Present Status

Based on the recommendations a group named Focus working Group on NGN was setup with in TRAI in May 2006 having representations from MN, FN, QoS, CN and Eco division to discuss NGN issues internally.

Terms of the reference of the NGN – eCO was made and circulated to various organizations seeking the representations.

NGN –eCO committee was formed in June 2006 having representations from 19 organization. There are total 30 members INCLUDING 5 members from TRAI.

Terms of reference of NGN – eCO contd.

3) Background information including best international practices for

Interconnection, QoS, Reliability, Billing, performance measurements and monitoring in the NGN

domain various regulatory options for enabling the same.

4) Any other task assigned by Authority.

Overview of NGN

CN Division, TRAI 9

Definition of NGN (ETSI)

NGN is a concept for defining and deploying networks, which due to their formal separation into different layers and planes and use of open interfaces, offers service providers and operators a platform which can evolve in a step-by-step manner to create, deploy and manage innovative services.

CN Division, TRAI 10

What is NGN?(From Common man’s point of view)

Next Generation Services – Converged (quad-play, voice, data, video, mobile)

Next Generation Access – High speed (Broadband) IP based connectivity (ADSL,VDSL, Wi-Max, Cable TV, FTTH.

Next Generation Transport – Ethernet, IP-MPLS Next Generation Architecture – Service oriented, layered

(transport, control, application) Next Generation Mobile – 3G+ Next Generation Internet – IPv6 Next Generation Interconnect – Capacity and Quality based Next Generation Licensing – Unified


Driving forces for NGNs

Integration of network resulting in huge network cost savings

Reduction in operational costs Reduced time to roll out new services Ease in offering new services (VoIP, IP-TV) Cost savings hence competitiveness

Advantages of NGN

NGN makes use of best of both the worlds (flexibility, efficiency & Innovativeness of IP and QOS, Security, Reliability, Customer-friendly features of proven PSTN

•Advantages for service providers Reduced CAPEX due to integrated and efficient IP-based

technology (Packetized Network) Reduced OPEX due to transmission cost saving, less power

consumption, less space requirement, less O&M costs Ability to offer increased range of services More flexibility increasing market penetration by offering personal

service customization and management Single network layer for management There is no need for separate voice and data networks


Advantages of NGN

•Advantages for subscribers

Reduced call charges

New innovative services

Single connection and bill for voice, data, video,

mobile (Quad play)

Better QoS

Faster speed

Availability of BW on Demand


NGN Components

NGN architecture breaks the hierarchy-based architecture of the Traditional Networks and advocates flat hierarchy for the NGN network.

1. Network Elements Converged IP/ MPLS Core (Soft switch/ media

gateway controllers) Intelligent Provider Edge (PE) devices for service

enablement (media gateway) Ethernet based Access infrastructure to aggregate

business and residential users Diverse set of access architectures in the last mile Home gateway or CPE


NGN Components

2. Service Control Elements Policy Control Framework for subscriber policy

tracking and enforcement Application level policy enforcement ‘AAA’ servers for billing and accounting &

Authentication

3. End User Devices (CPE) Converged devices can be intelligent TVs,

combined Mobile/ PDA/ Pocket PC/IAD

NGN Regulatory Challenges

As per ITU:-

“The move to NGNs represents an opportunity to establish in advance ground rules for ensuring the continued passage to effective competition and minimise damage during transition”.

It is in contrast to the regulation of the legacy network, which are actually in place. That is why, NGN is different.

ISSUES FOR IPLEMENTATION OF

NGN

NGN eCO meeting


NGN Regulatory Issues

Migration from service based licensing to service neutral licensing regime

Issues related with converged licensing Re-classification of the licenses Pricing issues to end users – Migration from

service based pricing to service neutral pricing Revenue settlement of the operators in NGN

environment


NGN Interconnect Issues

Migration from service based interconnection to service neutral interconnection

Reference interconnect offer (RIO) in NGN environment

Point of interconnect between various operators

Interconnection model Basis of charging Need for regulation of point of Interconnect

both in NGN and Non –NGN environment


NGN QoS Issues

Need to define Quality of services parameters in NGN environment

Monitoring QoS in various networks and ensuring compliance to defined QoS parameters in NGN environment

Ensuring End to End QoS across the networks Need to define unique service based priorities Reliability across diverse applications Encouraging network competition Mandating emergency numbers


Other Issues

Technical issues (To be addressed by TEC) Standardization of the interface for various services Backbone standardization and defining network parameters Management of security issues in NGN environment

Protection from various protocol attacks Application attacks SPAM VIRUS Misuse of OS vulnerability Spoofing on different layers Unauthorized user introduction Unauthorized access to system data Denial of services (DOS) and Distributed Denial of services attacks

(DDOS). Inter-operability


Other issues

Implementation issues Readiness of the NGN backbone Trail launch of NGN based services Defining point of Interconnect and Interface Definition of Uniform service based priorities Service authentication and Authorization Default service and routing requirement


Other issues

Work on ENUM

Implementation of IPV6

Legal Interception


Awareness Building Plan

the awareness about NGN and innovative services is

not yet widely spread

there is a great lack of awareness about various

issues pertaining to NGN among stakeholders

.


It is proposed to setup three core sub groups to deliberate on various identified issues. Regulatory issues Interconnect issues Quality of Service (QoS) issues

Core sub groups will have representations from various sector of Industry.

They will submit their paper on identified issue in two month time.

Way forward


Way forward contd.

Need to closely interact with international bodies like ITU, ETSI, 3GPP2, Regulators abroad etc. for obtaining latest information and knowledge related to NGN

Need to organize awareness programmes to educate other stakeholders in the country and make them aware of latest trends in NGN and its capabilities

Stakeholders can give their inputs to core group through e-Mail published on TRAI website for different core groups


Time frame for launch of NGN

Should some time frame be defined for launch of NGN

Should we concentrate policies on end to end NGN or limit it to core to start with.

What should be mile stones Redefining the licensing issues Standardization of NGN standards by TEC Interconnect model Setting of core network Interoperability test
