Challenges in NGN


3/23

NGN Features:

1. Next Generation Network

Conversed services:( Network, Service, Technology, Industry Convergence.)

Packet-based (IP) services, including voice, transportedtrough packets.

Issue ** In NGN network more reliable and guaranteedservice level for better approach of transmitting datapackets is required for multi-media and real time NGNservices.

Regulatory Authority along with operators, Investors,

Government should plan for: Better technological convergence.

Interconnection with standard interfaces.

Set certain QoS standards at each level of Interconnection.

Ensure the continuity of regulated interconnection services.

Plan for development of conflict resolution mechanisms.


8/23

Issue ** Due to Convergence, only the big players(Vodafone, AirTel, BSNL, RIL, Tata Indicom) may be able

to provide combined services which will lead to monopolyof few players .

Regulator has to see that market power will notdisappear in an NGN. Competition among all

operators (small or big like Uninor, YOU Telecom,Sify, Hathway or any or new entrants) must be ableto maintain healthy competition by:

Allowing number of operators to invest in NGN

at all levels. Charging minimum entry fees. Incentives to attract new entrants. USO funding


9/23

Issue ** Number of operators will be involved in network providingdifferent services as PSTN, WLL, GSM, Broadband, Data Services:

1. Vodafone and AirTel (Mobile-GSM, Broadband-2G/3G)

2. RCom ( Mobile-GSM/CDMA, Broadband-1G/2G/3G, Data),

3. BSNL ( PSTN-Wired, Mobile-GSM/CDMA, Broadband- Wired andWireless 2G/3G, Data Services),

4. Tata IndiCom ( PSTN-wired & Wireless CDMA, Mobile-GSM,Broadband-Wireless).

5. Sify, You Telecom, Hathway (Broadband-Wireless).

Regulatory Authority has to maintain the co-ordination amongservice providers, Various services, Investors and Government inorder to maintain Quality of services and smooth functioning at all

functional levels competition.


10/23

Issue ** For better implementation of NGN, high quality infrastructure evenlydistributed geographically in India is required.

Indian operators providing wireless services (Voice, Data, Mobile, andbroadband) . Quality of the services is not up to the mark due to poorexisting infrastructure in India. It is due following difficulties:

1. Limited number of own towers.

2. Operators not ready to share n/w of each other.3. Huge cost involved in tower installations and infrastructure

development.

4. Delay in permissions for infrastructure development from the localAuthorities.

5. Limited spectrum bandwidth.

Actually unbundling discourage new infrastructural investment but inpresent situation better infrastructure is possible by unbundling (sharing)of towers, OF cables, ducts.

Other than wireless media the only media which can support the quality

services in NGN network is Optical fiber cable, OF based n/w is limitedin India , in-between Telephone Exchanges and equipments only.


11/23

Regulator must plan for optical fiber infrastructure network (FTTH /FTTB) at National, Metro, District and Talula levels to support NGN.

It is difficult today due to:1. Local authorities not permitting to lay new cables.2. Heavy reinstatement charges.3. Heavy developmental cost are involved.4. Political pressures from local corporators.

Regulatory Authority along with Service Providers, Government bodies,Investors should plan for growth in OF network which is possible with:

1. Sharing of existing ducts, pipes along roads by all.2. The reinstatement charges should be minimized.3. FTTH/FTTB investment should be promoted with

. incentives.4. Plan for USO funding to cover the areas.5. plan for additional spectrum.

Wireless based Wi-fi, Wi-Max and GSM technologies should be plannedwith incentive schemes where the optical network is not possible/available

to cover scattered areas.


12/23

Issue ** NGN is having open Structure, separated

functional layers one can join at any level and share theinfrastructure. Number of operators(existing big/small,new entrants) in the n/w with different assets,investments.

It is suggested that there should be sharing of openinfrastructure in India.

Plan framework for sharing of n/w.

Interconnection models will be needed to address newarchitectures based on new parameters other thantraditional ones.


13/23

Issue ** There is need of allotment of additional spectrum to providequality services in NGN to match national and international standards.

Spectrum will be major source of wealth creation in comingcentury.

In India service providers provide services mostly on wireless(Voice, Mobile, Broadband and Data Services, Wi-Fi, Wi-Max,HDTV, mobile TV or 3G services). Additional demand for spectrumbecause of increase in customer demands.

Proper criteria for allotment should be adopted based on serviceproviders subscriber base, investment proportions, fixed assets

and revenues.

Allotment of spectrum to newcomers ?

Plan for open tendering, so that all can participate in spectrum

allocation which will support competition.


14/23

Issue ** Convergence in NGN leads to: Bundling of services

It becomes difficult for Regulator: To define markets, assess market power. More difficult to determine the extent to which prices

are cost oriented, allowing cross-subsidization betweenservices.

Customers may not want all the services: customer ischoosy.

To avoid above issues there is need to:1. Maintain Competition in NGN.2. Free entry to all operators at all levels of NGN.3. By offering combine services package with minimum

price will benefit customers.


15/23

Issue ** Unique network for all services, separate functional layers.

Service operators at all levels with combined services. There may besharing of infrastructures among several operators so that charging iscritical issue.

Existing charging principles/ costing model on interconnection is onthe basis of network resources involved in passing the traffic/delivery of service to end users.

All types of traffic in IP packets are delivered in different pathsin NGN there may be a need to review the existing costing andcharges methodology.

Planning for Call charging, routing of calls, Point of Intersection, atdifferent levels will be required.

Access emergency services are free of charge, from any telephoneas a welfare issue. This facility should be planned in the NGNnetwork.


16/23

Issue ** Migration to NGN involves very high costs:

Convergence of services (Voice, Data, and Internet),

Technological convergence (Wired-PSTN, Wireless-GSM,CDMA, TDMA, Wi-Fi, Wi-MaX ) .

Higher costs are involved in migration process than operation willbe managed through Incentives.

Cost reduction with selection of suitable fiber network topology(requirements and points of interconnection may differ which will

help in reducing infrastructure costs).

There should be balance of competition and investments at alllevels.


17/23

Issue ** NGN have different functional layers, levels, serviceoperators and converged Services.

One network multiple services, Mixed Technologies. Number ofOperators, Multi layers/levels in n/w, QoS is very important.

The standards of Quality of Services and Minimum Qualityparameters should be defined for all to ensure end-to-endquality of service within networks.

Proper Quality management control systems and appropriatemeasuring procedure should be there to analyze qualityrequirements to ensure QoS.

This may be possible with monitoring QoS at all levels ofnetworks.

To have quality services & applications in NGN, need morebandwidth, which could be managed with additional spectrumallotment.


18/23

Issue ** How to guarantee security? Management of security issues inNGN environment is critical one:

The Risk and threats in NGN may be due to external or internal

attack:1. Transmission of viruses and malware.

2. Cyber visitors.

3. Un trusted equipments used in the network.

4. Duplication of data.

5. Unauthorized Access to system information.6. Network becomes unavailable or unusable.

Due care will be taken to protect from internal and external attacks.

1. Needs appropriate levels of assurance from operators.

2. Manage security independently at respective levels ofarchitecture.

3. Strong binding of regulations for cyber owners.

4. Maximum punishment in case of violation of regulations.

4. Identity Management should be maintained throughout the

network

21/23

NGN still in Nascent stage in India.

NGN will change traditional face of telecommunication sector inIndia.

NGN incentives will attract both new entrants and existingoperators to invest.

NGN will be risky investment in present situation.

Uncertainty among competitors.

Most of investment will be done by Existing big players.

The NGN evolution will increase the competition.
