Ecma TC32 Activity Report 2007
Chairman:
Bernard Hammer (Siemens AG)
According to the
co-operation agreement between ETSI and Ecma International, Ecma TC32 acts as
the ETSI core competence centre for communications, networks and systems
interconnection in the field of private/corporate telecommunications. This
includes architecture, service, protocol, interoperability, management and short
range wireless communication.
During 2007 TC32 worked on various aspects of communication systems for
corporate networks, including the advancement of Computer Supported
Telecommunications Applications (CSTA), business communication involving Next
Generation Corporate Networks (NGCN) and public Next Generation Networks (NGNs).
Other topics have dealt with Near Field Communications (NFC) data link security
and the specification of the physical and link layer of high rate short range
communication systems.
The current focus of CSTA work is on a new standard on CSTA object model, the
second edition of ECMA/TR90 (Session Management, Event Notification and
Computing Function Services – Amendments for ECMA-348) and the second edition of
ECMA-366 (WS-Session – Web Services for Application Session Services). These
deliverables are planned for approval in June 2008. Further advancements and
maintenance of the CSTA technology will include work on new editions of
ECMA-269, ECMA-323 and ECMA-348.
In the area of NGCN, the committee is addressing the demand of enterprises for
cost effective and highly responsive business communication which integrates
Information Technology and telecommunication infrastructures. The
characteristics of NGCN include the consolidation of multiple services such as
voice, video and data into a single converged Internet Protocol (IP)-network,
hosted service provided by third party service providers and the support of
mobility features on and off campus.
Ecma TC32 has had intensive consultations with ETSI’s Telecommunication and
Internet converged Services and Protocols for Advanced Networking Technical
Committee (TC TISPAN) aimed at solving service signalling and management issues
for business communication across NGNs and NGCNs. In 2007 Ecma TC32 and TC
TISPAN jointly worked on business communication requirements, scenarios and
architectural requirements for core and enterprise NGN interaction and
architecture and the functional description of hosted enterprise services and of
business trunking.
In addition, Ecma TC32 has started new work aimed at producing a Technical
Report on NGCN in general which will cover framework and architectural aspects
of NGCNs and serve as an umbrella for a series of documents covering more
specific topics, such as identification and routing and NGCN – NGN interworking.
Other work has been initiated on the second edition of the Committee’s Technical
Report on enterprise mobility. This document will also serve as an umbrella for
a series of specific reports for example, on mobility management, identity and
access management and device management.
NFC is related to the contactless coupling of communication devices and smart
cards at low cost. The main aspect covered in 2007 was production of a framework
document and protocol suites on NFC Data Link security to complement higher
layer security. These will provide an application-independent security layer and
protection for NFC peer-to-peer communications against eavesdropping and data
modifications.
Further work either proposed or already planned for 2008 includes a second
generation NFC wired interface, higher data rates for the NFC Interface and
Protocol standard, application extensions, such as power control, and a standard
on 2,4 GHz high rate NFC.
Ecma TC32’s ‘High Rate Short Range Wireless Communication’ group is working on
wireless communication and the standardisation of Ultra Wide Band (UWB) using
Multi-band Orthogonal Frequency Division Multiplexing (OFDM). The UWB standards
ECMA-368 and -369 were revised in 2007 and published as second editions to
consolidate regulatory changes in the band-plan for use with, for example,
wireless Bluetooth. The second editions will also include ‘avoid’ measures; the
‘detect’ part of ‘Detect and Avoid’ is still under discussion and will be
included in the third editions.
With the completion of work on UWB, the focus has completely shifted to the
development of a physical and a link layer standard for the 60 GHz range for 2
to 10 Gbit/s data transport, ranging from file transfer with direct sight to
multi-path robust and high data rate video devices. The main focus of this work
will include modulation and coding schemes, waveform definition, error
correction, antenna training and link layer control and the interoperability
protocol.
