Approved by Board#68 - ETSI/B68(08)28 rev.3


TISPAN is the ETSI core competence centre for:

         next generation networks

         fixed network interconnection

        fixed network evolution and next generation network access, in conjunction with relevant ETSI bodies or external organisations, as appropriate, e.g. to avoid duplication of work..

          fixed network evolution and next generation network access

          migration from switched circuit networks to packet based networks with an architecture that can serve both

          interconnect scenarios, including but not limited to next generation corporate networks and next generation customer premises networks

          integration of multimedia services in the NGN (e.g. IPTV)

          customer premises networks and devices (layer 2 and above)

 TISPAN is responsible for coordination of NGN functions

  • where an IP Multimedia Subsystem is referenced; this is in conjunction with 3GPP and in accordance with the agreements regarding Common IMS
  • which require cooperation with appropriate ETSI bodies or external organisations.

With this understanding, TISPAN is responsible for all aspects of standardisation for present and future converged networks including the next generation networks and including service aspects, architectural aspects, protocol aspects, QoS studies, numbering, naming, addressing, routeing, security related studies, home devices and home networking aspects, network management, mobility aspects within fixed networks, using existing and emerging technologies. TISPAN work is in line with, and driven by, the objectives of the global ETSI membership.

TISPAN is structured as a single technical committee, with core competencies, under which there are Working Groups. Working Groups have specific core responsibilities and technical competencies. TISPAN has a programme of activities which are managed and organised by a hierarchical system in order to meet their objectives. The terms of reference of the Working Groups are to be found in separate documents.

TISPAN Core Competencies

         Definition of general network and service aspects for all existing and new generation access and core networks, in conjunction with relevant ETSI bodies or external organisations, as appropriate, e.g. to avoid duplication of work.

         Definition of the inter-working between traditional Switched Circuit Networks (SCNs), especially those served by PSTN, ISDN or PLMN networks, and the emerging NGNs.

         Definition of information transport capabilities, signalling requirements, protocol design and associated test specifications. The Adaptation, profiling and standardisation of protocols and protocol solutions.

         Definition of NGN home devices and home networking aspects considering layer 2 and higher layers. Regarding the layer 2 issues, TISPAN will have the ownership of the layer 2 related to the NGN home devices and networks and will closely coordinate with TC ATTM. Note: TC ATTM will keep the ownership of layer 1.

         Definition of mechanisms providing consistency and interworking between public & corporate networks and between fixed & mobile networks including ensuring that standards take account of regulatory requirements, security, lawful intercept, emergency communications, quality of service, numbering/naming, billing, mobility, service provider's requirements, and network management.

         TISPAN is focused on delivering the same level of quality and global connectivity from the new NGN and IP based services that are received from todayís public switched telephone network as well as new emerging services.

         TISPAN has activities that cover both circuit- and packet-switched networks including IP and ATM technologies.

         Maintenance of existing standards within the scope of TISPAN and its working Groups.

Collaboration with other bodies (both inside and outside ETSI)

In conjunction with the above Terms of References the following are noted:

         Providing overall guidelines to other ETSI Technical Bodies to ensure a co-ordinated approach to the development of standards for public networks including requirements from private networks;

         Primary Technical Body for co-ordinating the position of ETSI for ITU-T Study Groups as appropriate and/or as mandated by the board for the present study period);

         Primary Technical Body for liaising and collaborating as appropriate with the CEPT/ECC Project Teams (e.g. Numbering and TRIS)

         Liaising and collaborating with the European Union on regulation, EC Directives and other relevant issues

         Co-ordinating ETSI positions on network aspects as appropriate in IETF.

         Cooperation and maintaining good relations with other appropriate bodies, taking into account the list of ETSIís external relations agreements.
