Next Generation Networks

Introduction

The next-generation network (NGN) enables the deployment of access independent services over converged fixed and mobile networks – The NGN is packet based and uses IP to transport the various types of traffic (voice, video, data and signalling).

At the core of the harmonized 'ALL IP' NGN network is the IP Multimedia Subsystem (IMS) which provides an 'access independent' platform for a variety of access technologies (GSM, 3G, 4G, wi-fi, Cable, fibre and xDSL).

Standards for fixed NGN were developed by the now closed ETSI technical committee TISPAN. The TC has adopted the 3GPP™ core IMS specifications using Internet (SIP) protocols to allow features such as Presence, IPTV, Messaging, and Conferencing to be delivered irrespective of the network in use. Maintenance of NGN standards are now the responsibility of EP E2NA.

Our Role & Activities

Standards for fixed NGN were developed by the ETSI technical committee TISPAN (Telecommunications and Internet converged Services and Protocols for Advanced Networking). In 2012 TISPAN was closed and remaining work and maintenance was transferred to EP E2NA.

Release 1 

NGN Release 1 was finalized in December 2005, provided the robust and open standards that industry required for the development, testing and implementation of the first generation of NGN systems. NGN Release 1 specifications adopt the 3GPP IMS (IP Multimedia Subsystem) standard for SIP-based applications, but also add further functional blocks and subsystems to handle non-SIP applications. Initially work was performed on harmonizing the IMS core for both wireless and wireline networks. However early 2008, the common IMS specifications were transferred back to 3GPP so that one unique standards organization be responsible for providing a Common IMS fitting any network (fixed, 3GPP, CDMA2000, etc.). 

Release 2

NGN Release 2 was finalized early 2008, and added key element to the NGN such as IMS and non IMS based IPTV, Home Networks and devices, as well as NGN interconnect with Corporate Networks. IPTV specifications answer the market needs such as triple-play and quadruple-play service offers: access independent solutions, integration in a multi-service environment, availability of enhanced services combining features from every component of the triple/quadruple-play offers.

Two IPTV solutions were defined: an IPTV dedicated subsystem focused on the integration of existing market solutions in an NGN environment; and an IMS-based IPTV solution allowing blending the TV services with other Telecommunication services (e.g. voice, presence, and data services).

In the domain of Home Networks, the service requirements and capabilities for customer's home networks to be connected to the NGN were defined. This includes the definition of the Customer Network Gateway Architecture and reference points, and Customer Devices architecture and Reference Points.

To further enhance the IPTV support by the NGN, the architecture and reference points of a customer network device for IMS based IPTV services were specified.

Release 3

The third release of specifications addressed the following topics:

  • IPTV: New IPTV services have been defined including advertising, IMS enabled IPTV Roaming/Mobility, User Generated Content (UGC), and Personalised Channel (PCh)/User oriented content. The Content Delivery Network (CDN) was also defined. Peer-to- peer technologies for delivering IPTV services have been analysed. IPTV service protection was also addressed.
  • Enterprise networks with a NGCN-NGN Interface Implementation Guide
  • Network interconnection
  • QoS with an analysis is performed on the interaction of the Resource and Admission Control Sub-System (RACS) with the Customer Premises Network (CPN) in order to manage the resources inside the home network
  • Radio Frequency Identification (RFID) security
  • NGN security enhancements
  • Energy monitoring in the customer premises network
  • Regulatory issues
