Terms of Reference for TISPAN WG2
(Competence centre for Next Generation Network Services, Requirements and Architecture)

 

TISPAN WG2 is responsible for:

         Standards development activities related to NGN Services, Requirements and Architecture, and their evolution:

    • Conducting studies leading to deliverables on next generation services and applications (from the user perspective), and co-ordination and preparation of service descriptions for NGN
    • Conducting studies leading to deliverables on next generation functional and architectural requirements both from user and network perspective
    • Conducting studies leading to deliverables on next generation architecture as far as control aspects are concerned

         Coordination of NGN Services, Requirements and Architecture,

         Where an IP Multimedia Subsystem is referenced, ensuring alignment with the Common IMS specified within 3GPP.

         Service and Network inter-working and IP interconnection at the service, control and transport level, including but not limited to NGNs, Next Generation Corporate Networks (NGCNs), and next generation Customer Premises Networks (CPNs).

         NGN Multimedia services and architecture, including IPTV.

         Studies in the field of NGN mobility, including inter-working with existing and emerging IP-based Core Networks, which are beyond the exclusive scope of 3GPP. This includes Inter-access-system inter-operability, mobility and registration.

Activities:

         Standardization of NGN service descriptions from the user perspective

         Study the evolution of the NGN network architecture, motivated by new market requirements and considering new and emerging technologies

         Identification of generic functional capabilities required to develop a service independent architecture and definition of appropriate terminology

         Definition of functional architectures, taking into account related developments in standards for fixed and mobile networks to enable service and network convergence, as appropriate

         Definition and analysis of Functional Entities, Message Flows and Information Elements Identification of the need for reference points and standardised interfaces

         Analysis and comparison of interface requirements, including the impact on already standardised interfaces

         Development of requirements in the areas of work, including: architectural work; Security (coordinated with TISPAN WG7) Quality guarantees, network mechanisms and network aspects for both personal and terminal mobility/nomadicity

         Study of the impact of inter-working between similar and dissimilar NGNs that are evolving independently. Identification of the need for functional entities and reference points to support needed interfaces and protocols

         Consideration of mechanisms necessary to ensure proper interaction between services

         Monitor, support, and influence the work on services and architectures in other bodies

Collaboration with other bodies (both inside and outside ETSI)

         Cooperation with other ETSI Technical Bodies and Working Groups.

         Cooperation with other appropriate bodies, taking into account the status of ETSIís external relations.
