What is happening

How to balance reducing ARPU and manage growth:

– Use USO: for Tower, power, W/L and OFC penetration

– Bring in Virtual operator concept – Share Infrastructure

• Operators wants to penetrate into rural areas– But People have less paying

capacity (US$ 1-2 pm)– Thus Tariff is reducing– ARPU reducing

What is infrastructure

• Passive: Tower, Power, Land and Building etc.• Active

– Switches: TDM and IP based– Transport network

• OFC• Wireless: M/W, Satellite

– Access network• Copper: Local loop• Fiber: L/D, Back Haul and FTTX• Wireless: BTS

– Applications– Billing Systems

What to share?• Example of tourism Industry

– Bulk Ticketing, Pooled Pick-up drop, Bulk hotel booking, Group Sight seeing, Bulk lunch/Dinner

• Thus to get maximum benefit: Why not Share/Pool – Access Network– Carrier/Transport network– Billing System– Applications – Infrastructure passive and active– Common interconnect

Interconnect Issues• Separate Network for Basic/Mobile (Voice)

and for Data• Huge growth- Of the order of 15 Million

mobile connections in a month in India• Increasing numbers of Application

developers, no. of Oprs and their Traffic• Every Basic/Mobile operator have to have

interconnection (or transit through) with each other and with many NLD and ILD oprs

Results• Sub-optimal utilization of resources• Inefficient handling of calls• High operational cost for managing

inter operator connections• Inter opr/carrier billing problems• Complexity in settlement in

Interconnect usage charges• Increase in CAPEX and OPEX

Challenges

• Reduce High interconnection cost• Reduce Connection at different levels and

at many places and Complex routing at every point

• Reduce Huge requirement of ports and their cost

• Physical provisions at different places causes delay and need more capacity

• Resolution of billing disputes/court cases

What is the Solution: NGN:ICE

• Open and Fragmented Architecture• Best breed of products• Much Better Performance • Desired Quality of Service• Efficient inter working

‘And what not’ Thus NGN interconnect Exchanges can be

best solution for inter connecting

Advantages• Network planning fast and simple

leads to reduction in cost and port charges – Simple network interconnection using

Electrical/Optical, GE/STM interfaces– Reduction in number of links– Simplifies digit analysis for all inter

operator and long distance calls from the switches connected to it

Advantages contd.

• Fast provision/augmentation of PoIs as everybody knows physical location of IC

• Integration of different service providers at one point

• Help in quadruple (Voice, Video, Mobile TV and data) play in inter opr environment

• Help in convergence of services, application and provisioning

• Simplification in carrier selection function

Advantages contd.

• Integrated inter carrier billing/Clearing house – Less connection: less disputes: less court cases– Inter operator charging, based on GoS, Content and

network elements used in interconnection

• Intelligent network services– Easy provision in a multi opr and multi-service scenario– Content can be integrated at ICE and can be pooled to

all the operators connected to it

• Centralized LIS with artificial intelligence, Grid surveillance and encryption/decryption for voice and internet traffic

Advantages contd.

• Low latency and guaranteed QoS

• Reduction in Capex and Opex

• Down time can be reduced with resilient multiple node architecture

• FMC and Femto cell concept in multi operator environment in case of intra roaming, thus saving in spectrum

Implementation issues

• High upfront cost• Introduction of MG in case of TDM

switches with E1/STM connectivity• Introduction of SBC in case of IP based

switches with GE/MPLS connectivity • In domestic networks interconnect

exchange (one or two depending on the business case) at charging area level and at Metro-city level

• Duplicate connectivity or connectivity through Self healing rings

Colombo, April 9, 2009

H C SONI 18NGN Standardization

Implementation issues contd.

• Migrating TDM switches to IP based architecture

• Circumventing Security risks and ensuring hassle free LI

• For few years existing Interconnect regime has to continue and in parallel NGN based interconnect Exchange

• Duplication till full shift to IP/ICE but better in long run

• UASL operator with centralized control of MG/SBC distributed in service area

Colombo, April 9, 2009

H C SONI 19NGN Standardization

Implementation issues contd.

• NLD/ILD operators may have centralized control at two places for geographical redundancy

• By and by migration to NGN switches in the network and IP based interconnection

• Integrating Voice, Video, Data & IPTV• Charging scenario will change but will be

more versatile: Old Distance/Time based may be replaced by NGN based: QoS, B/W, Appln, Supplementary & VAS

Who will do it?

• Regulator and licencer: terms to be redefined with light touch approach

• All stake holders to come to gather• By incumbent operator or by other or

by a separate independent operator• Management by: To be decided by all

stake holdersThis is about ICE What about others?

So Perhaps in Future NGN will give

• Separate access providers: DSL, Wi-Fi, WiMAX, FTTX, GSM, CDMA, 3G, 4G and xG etc

• Separate: network provider with NGN core• Separate: long/short distance connectivity providers:

by most Optimal Carrier Ethernet• Separate Infra: Tower, Power, BTS providers• Separate: Application Service providers• Strong Marketers with innovative ‘Tariff Products’

giving cheapest service to Public• Bring MVNO/ Virtual Operator concept AND

‘Specialized people will maintain different entities, conveniently and in the

Cheapest way’
