Seminar Contents


The 5 days seminar starts Monday morning and ends Friday afternoon (see dates at the right column).

The seminar is organised in eight parts:

  • AMHS Basics
  • Gateway/1 (operational aspects)
  • AMHS Routing
  • Extended AMHS
  • MHS Procedures
  • MHS Information Objects
  • Gateway/2 (technical aspects)
  • Regional Implementations

AMHS Basics – This part provides a basic overview of the AMHS communication concept and the services offered to AMHS users. Major topics are the AMHS architecture (in terms of functional components, information objects and protocols), supported data types and user addressing. The presentations focus on the Basic ATS Message Service as currently implemented by most of the ANSPs. Explanations are given how elements of the ISO/IEC MHS standard form the platform of the AMHS. Supplementary information relates to the embedding of the AMHS in the ATN environment and provides the background of the ICAO standardisation work. The concluding section handles the current migration of the ATN from ISO/OSI communication (ATN OSI) to the Internet Protocol Suite (ATN IPS).

Gateway/1 – This part is dedicated to the operational aspects of the AFTN/AMHS Gateway. The audience is provided with the taken conceptual approach and the conversion mechanisms. Operational limitations of the gateway and needed operator assistance are identified.

AMHS Routing – This part provides firstly an introduction to network topology aspects and common routing strategies upon them with the focus on AMHS. In detail, the developed concept for AMHS routing in the European Region is presented. In addition, routing issues during the transition phase from AFTN/CIDIN to AMHS are discussed. A concluding section illuminates the technical support given by the European ATS Messaging Management Centre (AMC).

Extended AMHS – This part deals with the enhancements added to the Basic ATS Message Service, i.e. support of unstructured binary data, secure messaging, use of directory services and use of MHS service elements not yet available at the time of the initial AMHS specifications.

MHS Procedures – This part is concerned in detail with procedures, operations and protocols defined with the ISO/IEC MHS standard and adopted for the AMHS. In addition, the components defined at the Application Layer for MHS communication are explained and the related parameters needed for establishment of connections between adjacent AMHS systems are indicated. 

MHS Information Objects – This part presents in detail the construction of MHS information objects and related communication services and indicates their relevance for AMHS. The reader is provided with sufficient knowledge about MHS features to understand in detail the conversion mechanisms in the AFTN/AMHS gateway as handled in the part Gateway/2.

Gateway/2 – This part presents details of the mutual mapping process between AMHS and AFTN information objects. Situations where mapping fails are examined. The provided information supplements the presentations given in Gateway/1.

Regional Implementations – This part gives an outline of the planning activities conducted in ICAO Regions for a coordinated AMHS implementation. In particular, Regional AMHS Profiles are explained as well as the developed specifications for AMHS conformance, interoperability and pre-operational testing. The concluding section informs on the implemented centralised AMHS off-line management functions which form a functional area of the AMC. Generally, this part indicates the scope of needed agreements and provisions of common facilities at the level of ICAO Regions to close such functional areas which are seen in the AMHS technical specification as “implementation matters”. The given information is useful in preparation for forthcoming inter-regional coordination activities.
