Emerging developments in ICT Technologies

•         Increased speed and density of Integrated Circuits (Moore's Law-CPU processing power doubles every 18 months).

•         Enhanced Transmission capacities on Optic Fiber Networks and Networking Flexibility (Gilders Law-OFC carrying capacity doubles every 6 months).

•         Distributed and Open Platform-based Communication Software (APIs).

•         Capacity Growth and new Application Services on Wireless (Coopers Law-wireless capacity doubles every 30 months).

•         Emergence of all-IP based networks (Next-Generation Networks) .

•         Carriage of real time QOS- requiring multimedia traffic by data networks (VOIP, IPTV, VOD, IM)


All-IP Networks-NGN


•          Next Generation Networks (NGN) are the systems based on emerging  Packetization technology of IP which is leading to convergence of networks, services and markets and enhancing efficiency and flexibility.

•          Rapid technological developments are taking place in transmission networks (optic fiber), access networks  (wireless), switching (IP) and customer premises equipment (Integrated and Intelligent).

 Wireless based access technologies specially EVDO, Wi-Fi, Wi-Max, LTE are making broadband access faster and cost effective.

•         These developments are enabling the operators to increase their depleting ARPU( Average Revenue Per User) by providing advanced value added services in  addition to plain Vanilla voice.

•         Emergence of EOIP which means Everything over IP.  That means you can provide any service through Next generation platform based on All- IP.

•         NGN with the help of soft-switch can co-exist with the legacy PSTN networks and hence the existing investments of operators do not go waste. 

•         NGN is capable of providing seamless converged services from telecom, internet and broadcasting infrastructure at any time, anywhere to anywhere from any device to any device. 

•         Many countries like UK, Japan, Korea, Malaysia, Italy, Singapore,                     Vietnam and China have decided to migrate to NGN. The incumbent operators there are going for NGN and replacing their existing networks to IP -based in a time bound manner.  This is being done to beat to competitors and new entrants on the technology front and being able to provide new value added services, cut down on Opex as well as to make the network future-proof.




What is All IP-NGN Ecosystem?(From Layman’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, PLC)

•                     Next Generation Transport – Carrier 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 and Class Licensing

•                     Next Generation Regulation – Converged (Single Regulator for

•                       ICE)

Definition of Next Generation Network (ITU)

Next Generation Network (NGN) is a packet-based network able to provide services including Telecommunication Services and


       Able to make use of multiple Broadband, QoS-enabled transport technologies in which service-related functions are independent from underlying transport-related technologies;


       It offers unrestricted access by users to different service providers.


       It supports generalized mobility which will allow consistent and ubiquitous provision of services to users.  


Advantages of All-IP 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

ό                  Reduced CAPEX due to integrated and efficient IP-based technology

           (Packetize or Perish)

ό                  Reduced OPEX due to transmission cost saving, less power

            consumption, less space requirement, less O&M costs

ό                  Ability to offer increased range of services

ό                  More flexibility increasing market penetration by offering personal   service, customization and management

ό                  Single network layer for management

ό                  Avoidance of separate voice, broadcast and data networks


•         Advantages for Customers

ό                  Reduced call charges due to efficient operation and competition

ό                  New innovative services at a fast speed

ό                  Single connection and bill for voice, data, video, mobile (Quad play)

ό                  Control of application service for flexibility

FMC (Fixed Mobile Convergence)

NGN based Emerging Services-FMC

 (Fixed Mobile Convergence)

FMC is convergence of multiple access media ( Fixed, Mobile, Internet) for telephony wherein as per

the convenience of the user, an mobile call can be delivered

on fixed phone or can be terminated through fixed Broadband

network on hand-held device (e.g. mobile phone) and vice-versa. 


Main motivation for this is :-

1.         Spectrum shortage leading to congestion and reduced QOS. (It is believed that 70% of the time a mobile call recipient is at a fixed location/Hot Zone)

2.         Mobile subscribers saturation, Fixed lines decline (Battle for in-building minutes)

3.         Broadband becoming ubiquitous and cost effective

     4.      The “Mobile Handset” is becoming a multi-mode, multi-band,  Multi-Purpose hand-held computer

     5.  NGN Technologies enabling FMC (IMS, UMA, Femtos, E.Num)








          FMC Challenges-India

•                     Number plans and number portability

–                    Fixed and mobile numbers come from separate blocks and

                       they have prefixes that contain information for interconnection


–                    Currently mobile number portability (MNP) available but not

            fixed/mobile number portability

•                     Directory services

–                    Fixed operators provide directory service to their customers.

            This catalogue contains information on all fixed line customers

–                    Currently mobile operators do not offer this kind of service

            and mobile numbers are considered as personal subscriber


•                     Handset availability

–                   Unavailability of Wi-Fi enabled multi mode handset (always a

             problem in the early stages of any telecommunications


•                     Role of regulators

–                    Permitting interconnection of PSTN and Internet networks.

–                    Determining IP termination charges inline with MTC (mobile termination charges).

–                    Unify the Numbering system for fixed and mobile , move toward E.Num

–                     Regulators should only establish the facilitating interconnection rules so that the market forces can guide direction, extent and pace of FMC
