ETSI already addressing similar topics or complementary ones. It will also
identify and monitor relevant work items of independent external entities which
are important for network standardization.
It is recognized
that specific parts of architecture and technology are being developed and
standardized for different sectors of the telecommunication industry. These
specific parts remain of interest to the member TCs and are expected to be
developed by them independently.

ETSI Project E2NA
is initially composed of the following ETSI organizations:
E2NA will have a
Plenary Assembly responsible for the technical program of the project and its
management and organisation, assuring an end to end system view and global
consistency of the results produced.
service requirements and architecture will be defined at EP level while detailed
technical work (detailed architecture and protocols) will be delegated to the
relevant member Technical Committees.
Collaboration with other bodies (both
inside and outside ETSI)
with its mission and limits there from,
EP E2NA will:
Cooperate with 3GPP, BBF and any other groups on relevant
topics, including fixed and mobile interconnection and
Provide overall guidelines to other ETSI Technical Bodies to
ensure a co-ordinated approach to the development of standards

networks; Act as the primary contact for co-ordination between
ETSI and the ITU-T Study Groups involved in current and future
Act as the primary contact
