What is a Next Generation Network?: What is a Next Generation Network? Layered instead of monolithic architecture
Open standard interfaces between the layers and all other networks
Seamless control of multiple transport technologies
Use of standards based components ” NGN means different to different parts of the Industry…
So which definition is correct? “A public packet based communication network integrating voice, data and enhanced multimedia services with the following characteristics: NGN motivating point: It enables New Services and therefore New Revenues...
ETSI -The NGN goals: ETSI -The NGN goals The Next Generation Network will eventually provide:
A multi-service multi-protocol, multi-access, IP based network that is secure, reliable and trusted
Multi-services: delivered by a common QoS enabled core network
Multi-access: diverse access networks; fixed and mobile terminals
Not one network, but different networks that seamlessly interoperate
An enabler for Service Providers to offer
real-time and non real-time, communication services
between peers, or in a client-server configuration
Mobility / Nomadicity
for both users and devices
intra and inter-Network Domains, between Fixed and Mobile networks
Interactive “My communications services”
anywhere, any terminal, anytime
NGN@Home: NGN@Home Terms of Reference
Co-operate with all parties, both internal and external to ETSI, in order to meet the objectives of NGN@Home
Act as the focal point for matters related to Home Networking within TC AT and as a Project with TC TISPAN
Study the interworking and compatibility between all Home Network components, in-home features and services for NGN
Define the components and functions of the Home Residential Gateway (Addressing, Management, Protocols, Connectivity, QoS…) for the support of various in house applications for the reliable delivery of services to the end devices within the HAN
NGN@Home Standardizations Involvement: NGN@Home Standardizations Involvement AT HF TISPAN 3GPP AT-F Cenelec Home Network Related Collaboration AT-N AT-I AT-D AT-A NGN@Home is supporting the European Commission in its goals for a universal access to Information and Communication Technology (ICT) by producing the necessary standards to accommodate the needs for all including the disabled and the growing number of older users
NGN@Home Architecture General Requirements: NGN@Home Architecture General Requirements Internetworking
Existing networks must be interconnected
Robustness
For the loss of network or parts of it
Heterogeneity
Consider a variety of networks including broadcast, satellite, wireless/radio and other networks
Distributed Management
Permit distributed management of its resources
Ease of Attachment
Permit host attachment with a low level of effort
Accountability
Resources must be accountable
Home Networking: Home Networking The objective of the project is to define and demonstrate an open network architecture enabling the provision of services to the users in its home, and in nomadic situation.
1. Build a multi-services home network based on a Residential Gateway (RG) that acts as a service platform for the end user. The RG embeds the Home Agent (HA) that allows remote management of the home network by the home network service operator.
2. Build a powerful and networked management tool. This tool is a software platform located for example in an ISP or ASP premises. This platform inter-works with the HAN.
3. Offer Remote Access (for mobility and also a visiting connection) in a secure way to the home resources via mobile phones, PDAs, laptops or workstations.

Emergency:
Emergency calls from within house/home or even a car, rerouted through Home RG to appropriate call center.
Human Factors Activities supported by NGN@Home: Human Factors Activities supported by NGN@Home Standardisation:
Secure networks
Digital Rights Management
End User Aspects:
Design and Accessibility (children, elderly, disabled)
Enabling Users for Mobile Services
Person-to-Person Video-telephony
Telecare Solution
User profiles - increasingly important for customisation of terminals and services to provide efficient communications and the universal acceptance and success of new and advanced communication services.
Conclusions: Conclusions Ensure a global user approach, independent of a specific access technology
Define a reference architecture and network functions required to support home and/or nomadic users
Define required interfaces for these functions in the control layer for the terminals and the applications Standardisation activities for management in Next Generation Home Networking:
