Next Generation Networks-Expectations and Goals

Presented by- Aditya MathurA1607110024

Next Generation Network-What it is?

A next-generation network (NGN) is a packet-based network which can provide Telecommunication

Services and able to make use of multiple broadband, quality of Service-enabled transport

technologies and in which service-related functions are independent from underlying

transport-related technologies. It offers unrestricted access to users to different services. It supports generalized mobility which will allow

consistent and ubiquitous provision of services to users.

Architecture

The NGN follows the 3GPP’s IMS architecture.

IMS- IP Multimedia Subsystem, it is based on IP and supports multimedia services (voice, video, gaming, conferencing etc.),

IMS can seamlessly integrate with other systems via appropriate adapters/mediators or interworking elements.

The Functional Entities(FES) in the IMS layer interact with the Applications and Services layer FES to provide enhanced services.

Network Convergence PSTN(fixed) and 2G/3G carry voice and data Fixed and mobile networks are converging. The voice, data, video etc., all are transported over

one IP based network.

NGN being an IP based network, targets IPv6.

Internet Protocol (IP): The NGN Glue

The Internet Protocol (IP) is the principal communications protocol used for relaying network packets across an internetwork using the Internet Protocol Suite. Responsible for routing packets across network boundaries, it is the primary protocol that establishes the Internet.

Available Versions-

IPv4: Uses 32-bit (four-byte) addresses

IPv6: Uses 128-bit addresses

MIPv6 (Mobile Internet Protocol version 6): It is an Internet Engineering Task Force (IETF) standard communications protocol that is designed to allow mobile device users to move from one network to another while maintaining a permanent IP address.

NGN: Goals

Quality of service (QoS)

Security and robustness.

Network management, including the allocation and sharing of bandwidth.

Systems engineering and operations, including definitions and tools for service architectures, metrics, measurement, statistics, and analysis

New or modified protocols for routing, switching, multicast, reliable transport, security, and mobility

Collaborative and distributed application environments

NGN: Goals

Cost effectively provide new services.

NGNs will enable carriers to deploy advanced services, allowing them to remain competitive as well as expand their capabilities to enter new markets.

NGN: Services

The Next Generation Network is a bundle of services, currently available and many yet to come.

Available Services- Specialized resource services

(e.g., provision and management of transcoders, multimedia multipoint conferencing bridges, media conversion units, voice `recognition units, etc.)

Processing and storage services (e.g., provision and management of information storage units for messaging, file servers, terminal servers, OS platforms, etc.)

Middleware services (e.g., naming, brokering, security, licensing, transactions, etc.)

Application-specific services(e.g., business applications, e-Commerce applications, supply-chain management applications, interactive video games, etc.)

Content provision services that provide or broker information content (e.g., electronic training, information push services, etc.)

Interworking services for interactions with other types of applications, services, networks, protocols, or formats (e.g., EDI translation)

Management services to maintain, operate, and manage communications/computing networks and services.

Expected Service support

Voice Telephony (e.g., Call Waiting, Call Forwarding, 3-Way Calling, various AIN

features, various Centrex features, and various CLASS features)

Data (Connectivity) Services (e.g., bandwidth-on-demand, connection reliability/resilient

Switched Virtual Connections [SVCs], and bandwidth

management/call admission control).

Multimedia Services Allows multiple parties to interact using voice, video, and/or

data. This allows customers to converse with each other while displaying visual information

Unified Messaging Supports the delivery of voice mail, email, fax mail, and pages through

common interfaces.

E-Commerce Allows consumers to purchase goods and services electronically over the

network. This could include processing the transactions, verifying payment information, providing security, and possibly trading.

Interactive gaming Offers consumers a way to meet online and establish interactive gaming

sessions.

Home Manager With the advent of in-home networking and intelligent appliances, these

services could monitor and control home security systems, energy systems, home entertainment systems, and other home appliances.

Expectations

Software-Based Business Communication Service

High-Definition (HD) voice

Mobile and Managed Peer-to-Peer (M2P2P) Service

Wireless charging of hand held devices.

Three Dimensional Televisions (3D-TV)

Converged/Personalized/Interactive Multimedia Services.

Grand-Separation for pay-per-use Service etc.

Conclusion

Next Generation Network is the concept of a network that could transport all information and services (voice, data, and all sorts of media such as video) by encapsulating these into packets, similar to those used on the Internet. NGNs are commonly built around the Internet Protocol, and therefore the term all IP is also sometimes used to describe the transformation toward NGN.

We discussed various services and goals related to the NGN concept.
