Profile for ATS Messaging using AMHS and TCP/IP
Ref : DAS/CSM/ARCH/EUR-AMHS
1.INTRODUCTION
This Profile brings together a set of specifications of ATS Message Handling Systems from the ISO/IEC base Standards, ICAO Document 9705 Ed. 3, and requirements from the SPACE project. This EUR-AMHS Profile collects them for use in specification and procurement of AMHS systems based on TCP/IP used to support the ATS Message Handling Service in Europe. Its scope is limited to the specification of those aspects of systems that are involved in exchange ATS messages between international COM Centres. Other aspects that involve gateways e.g. to the AFTN and CIDIN, or communications that remain entirely within an ATSP’s State are not dealt with in this Profile.
Specification of an AMHS based on TCP/IP necessarily references a wide range of standards from different sources. This is complicated by the fact that procurement of a complete AMHS/TCP solution involves the specification of three different system component types (Message Transfer Agents, Message Stores and User Agents), each of which has a number of implementation options. This Profile therefore also provides guidance on the correct use of the referenced ISO/IEC ISPs, ICAO Documents and Internet RFCs for each type of system.
Document Structure
Section 6 specifies the requirements for each different type of AMHS system (ATS Message User Agents and ATS Message Servers) in terms of the requirements of their component parts (UAs, MTAs and MSs). The requirements for each of these are then specified in detail in a set of Annexes (A to P).
Annex Q provides a set of Implementation Conformance Statement Proformas for each type of component. These proformas are intended to be completed by AMHS system suppliers as a part of the procurement process.
Relationship to other Standard Documents
This Profile is based on the set of ISO/IEC International Standardized Profiles (ISPs) in the AMH1n and AMH2n ranges.
It also references the following Sub-Volumes of ICAO Document 9705, Edition 3:
- Sub-Volume I (Introduction and System Level Requirements),
- Sub-volume III (Ground-Ground applications), including the ATSMHS specification,
- Sub-Volume VII (Directory Service),
- Sub-Volume VIII (Security Services),
- Sub-Volume IX (Identifier Registration).
Some of the input requirements also stem from the CEC TENS “Study and Planning for AMHS in Europe” (SPACE) project.

2.Scope
This Profile specifies a number of AMHS protocols and systems capabilities for the exchange of ATS messages between direct and indirect AMHS users through ATSP’s international COM Centres.
This Profile is applicable to the following aspects of message Interchange:
- Transfer of messages between the AMHS systems at International COM Centres operated by different ATSPs;
- Submission, Delivery and Retrieval of messages that are to be transferred between AMHS systems operated by different ATSPs;
- The content of Message Envelopes, IPM Headings, Body Part Types and AMHS Addressing used for the protocols identified above.
This Profile does not specify any of the purely local requirements within an ATSPs individual systems – e.g. MTS Access, MS Access, and interconnections between MTAs within an ATSP’s Private Management Domain other than to ensure adequate interchange of ATS messages internationally. Nor does it specify aspects of interconnections between regional AMHS/AFTN or CIDIN gateways where additional requirements may apply, such as support of an ATN lower layer protocol stack as specified in ICAO Document 9705 Ed. 3 Sub-Volume V.
Access to the Directory Information used to support Directory Name Resolution and address mapping between AFTN and AMHS address forms is indicated for information only.
The following diagram illustrates the scope of the protocols and system types specified in this Profile.
Figure 1– AMHS Systems and interconnecting Protocols
This Profile applies to the following AMHS system components:
- User Agents UA
- Message Transfer Agents MTA
- Message Stores MS
This Profile applies to the following AMHS protocols:
- IPM Content P2
- Message Transfer P1
- Message Submission/Delivery P3
- Message Retrieval P7
This Profile specifies a Profile of ATS Message Handling Service conformance called the EUR-AMHS Profile. It is based on the requirements of following:
- The Basic ATS Message Handling Service (Bas), introduced in the Doc. 9705 Ed. 3 3.1.1 Note 2;
- A number of further Functional Groups and options selected from the Extended ATS Message Handling Service (Ext), introduced in the Doc. 9705 Ed. 3 3.1.1 Note 2;
- Further requirements specified by the SPACE Final Report for use in Europe.
Security requirements are not a mandatory part of this Profile. However, it mandates IP address validation and the protocol includes system identification following transport connection establishment. Certain Messaging Application Security functions are also mandated in the MHS S0 optional Functional Group for the Extended ATS Message Handling Service. However, they are not mandated by this profile.

3.1Introduction
The following documents and standards contain provisions which, through reference in this text, constitute provisions of this Profile.
At the time of publication of this Profile, the editions indicated for the referenced documents and standards were valid.
Revisions of the referenced documents shall not form part of the provisions of this Profile until they are formally reviewed and incorporated into this Profile.
In case of conflict between the requirements of this Profile and the contents of the referenced documents, this Profile shall take precedence.
3.2Referencing the ISP 1st, 2nd and 3rd Editions
Document 9705 Ed. 3 refers to Edition 1 of the ISPs to define the Basic ATS Message Handling Service, and it refers to Edition 3 ISPs to define the Extended ATS Message Handling Service. Edition 2 ISPs are not referenced.
This situation complicates the specification of this Profile, because it references both the Basic and Extended ATS Message Handling Services. The Basic Service definitions in Doc. 9705 Edition 3 should be updated to refer exclusively to Edition 3 ISPs – thus eliminating all references to Edition 1 ISPs.
In the meantime, this Profile, and the profiling tables in its annexes all refer to the elements of the 3rd Edition ISPs. Annex R provides a mapping between the elements of Edition 3 to the corresponding elements of Edition 1 ISPs.
