Next Generations Networks
Evolution of New Services
Arrival of new Telecom services, fast packet
switching and enhanced VVD laid the foundation of a New Generation of Networks
or NGN for new generation of services.
What is NGN?
- NGN is Voice Over IP, bypassing the regular switches to save the investment on Switches and Trunks.
- NGN is network convergent technology, combining Wireline (PSTN), wireless (GSM, CDMA and 3G) and packet data network together, for integrated voice, data and multimedia services.
- NGN is a flat telephone network over Packet Data Network, instead of traditional Hierarchy structured telephone network with reduced investment.
Why NGN? (New Generations Networks)
- Increased demand for bandwidth is not possible through existing PSTN ( Public Switched Telephone Networks).
- Requirement for new generated and Upcoming services.
- Telecom operators want to reduce the OPEX and CAPEX (Need one common network for all services).
- Future proof network to handle Voice, Data and Multimedia.
- Optimising and simplifying transmission links.

customers. These high bandwidth
offerings are all able to support multi-play options including broadband
Internet, telephony, television and mobile services. In countries with high
broadband penetration levels, evolved DSL platforms and increasing fibre to the
home offerings, VoIP telephony and video calling has become the norm for end
user communication.34 Fixed line usage is declining for classical voice
services, mobile services growth continues and broadband Internet deployment is
showing rapid growth as well. As newer and more innovative services Consumer
demand for NGN services is difficult to quantify currently where large
uncertainty remains regarding the exact nature and scope of services. However,
where affordability and access are not barriers to development, consumer demand
for high end, innovative and evolving services as user patterns change is matched
only by limitations on bandwidth. A sampling of currently available bandwidth
offerings includes in Morocco, 20Mbps; the UK, 8Mbps and upwards; 24Mbps in
France, and 100Mbps and rising in markets like Japan, South Korea, Hong Kong
and Singapore, the latter having set 1Gbps as a target. It is expected that access
networks in the future will provide bandwidth of up to 100Mbps for individual
users and transmission rates in the gigabyte range for commercial and
applications become available, operators worldwide are seeking new solutions to
adequately address demands being placed on them by consumers and technological
developments. At the same time, consumer needs are also maturing with increased
choice in offerings, reduced prices and discounted bundled products. Consumers
are also seeking simplicity in billing and increased personalization with full
mobility and increased quality of service.
For individual consumers, the demand for
broadband to the home, offering on-demand multimedia services is increasing in
countries that have the infrastructure to support such demand. As services and platforms
converge, consumers also seek attractive pricing bundles for their combined
voice, data and video needs, across both fixed and mobile networks. This is
also fuelled by increases in local and cross border communications for personal
and business purposes, including telecommuters who work from home or abroad,
requiring high performance, widely available, secure voice and data services.35
Similarly, business enterprise users are seeking integrated voice, data and
video services as well as ubiquitously available electronic communications
services with high speeds and flexibility. While business users also seek flexible
virtual private network (VPN) solutions, overall, commercial customers are
demanding more innovative services and network intelligence – security,
storage, application layer routing and adaptability – to support the trend in
enterprise markets toward better integration of their networking and information
systems.
