TRIS - TISPAN WG4 workshop on NGN Interconnection and Numbering
Wednesday 18 January 2006, starting at 0900
European Radiocommunications Office
Nansensgade 19
DK-1366 Copenhagen
Phone: +45 33 89 63 00

To explore:

• the technical, operational and commercial issues relating to the interconnection of NGNs;
• the implications for interconnection of numbering and quality issues;
• the options for backbones and transit networks and the provision of facilities such as ENUM and DNS;
• the practical issues of migrating from existing networks and rolling out new services;
• the retail and interconnection charging models for services on NGNs.

The workshop aims to bring together technical, operational and commercial experts for a joint discussion of these overlapping issues. Recognising that different attendees will have different interests, the aim is to establish better understanding of the interactions between the issues that will feed constructively into strategic thinking about the design and implementation of NGN and the extent to which cooperation may be needed for the provision of common facilities.

The workshop will use some information about developments already in progress such as BT's 21C as "case study" examples that will highlight practical issues.

The format of the workshop will be short presentations interleaved with discussion around a set of prepared questions.
