Data Communication Services (6.2)

• Examples OLDI, CPDLC, CDM, ASAS, Met data, ...
• Strategy
• To evaluate requirements, specify and implement
  new data communication services based on evolving
  or new operational concepts (Vol1, Ch4)
• Changes
• Study criteria to select data distribution
  mechanism point-to-point (EAD model) and/or
  store and forward (AMHS)
• External communication services for Air Defence
  and Meteorological info

• To evaluate the end-to-end performance
  requirements relating to signalling and speech
  quality... (Vol1, Ch4)

PENS Data Networks (6.4.2)

• Strategy
• To implement the transition from legacy CONS to
  high QoS COTS-based IP technology to support
  current and future application requirements
  (Vol1, Ch4)
• Changes
• Implementation of ECAC wide IP network
• Migration of OLDI to IP Migration of ASTERIX
  (for surveillance) application to IP
• ATN air-ground data (e.g. CPDLC) over IP ground
  networks

PENS - Message Handling (6.4.2)

• Strategy
• To implement an international Aeronautical
  Message Handling Service (AMHS) with appropriate
  Gateways to AFTN (ECG) (Vol1, Ch4)
• Changes
• Implementation of AMHS over TCP/IP in the EUR
  region
• Migration of AMHS to an IP COTS-based messaging
  (long term)

Voice Fixed Network Services (6.4.3)

• Strategy
• To implement an improved digital signalling
  system (ATS QSIG and PNNI) for ground-ground
  voice communications to replace analogue
  signalling systems (e.g. MFC-R2) (Vol1, Ch4)
• To evaluate End-to-end performance requirements
  relating to signalling and speech quality,
  including consideration of the potential benefits
  of Voice over IP (Vol1, Ch4)
• Changes
• Support to B-QSIG withdrawn in favour of VOIP
• Transition from analog to digital signalling
  system spread over longer time frame
• Slower introduction of intl VOIP

Mobile Network Services (6.5)

• Strategy
• To implement a VDL-Mode 2 air-ground sub-network
  as the first ATN sub-network, for operation in
  the short term (Vol1, Ch4).
• Continue the feasibility analysis, to define the
  baseline for next generation mobile
  communications systems, to support ATM voice and
  data services beyond 2010, (replacing To
  study the requirements for future air-ground
  sub-networks, in order to identify candidate
  solutions for beyond 2005 (Vol1, Ch4)

Mobile Network Services (6.5)

• Changes
• 8.33 kHz - Vertical Extension update following
  decision at ICAO/EANP 44
• Inclusion of Satellite and Wideband as possible
  Next Generation Systems
• Removal of Gatelink as possible technology to
  support ATS air/mobile applications
• For surveillance applications (e.g. ADS-B)
  Extended Squitter complemented by VDL4 (pending
  study results)

System Wide Aspects

• Strategy
• To implement systems management in support of
  network services on an international basis (Vol1,
  Ch4)
• To evaluate the adoption of industry standards
  and COTS products and services for future
  aeronautical applications (Vol1, Ch4)
• To conduct a study to specify and standardise
  ECAC-wide security mechanisms (both technical and
  procedural) to protect information flows from
  attack and cyber-terrorism using the
  ground-ground or air-ground communications
  infrastructure (Vol1, Ch4)
• To support ongoing improvements in the management
  of frequency spectrum for aeronautical purposes.
  To promote the interests of the aeronautical
  community at the appropriate international fora
  for spectrum allocation. (Vol1, Ch4)
• Changes
• Emphasis on mechanisms to protect against
  cyber-crime and cyber-terrorism
