SIST-TP ETSI/ETR 091 E1:2005

SIST-TP ETSI/ETR 091 E1:2005 is the Slovenian adoption of ETSI ETR 091 Edition 1, an ETSI Technical Report on the ETSI object identifier tree. It defines the mobile domain within the common domain and shows how mobile-service object identifiers are structured for ETSI work on GSM-related specifications.

What does SIST-TP ETSI/ETR 091 E1:2005 specify?

SIST-TP ETSI/ETR 091 E1:2005 specifies the structure of the mobile domain inside the common domain of the ETSI object identifier tree, as defined in ETS 300 351. The document gives both the tree view and an ASN.1 description, so readers can see the naming structure and the formal identifier definitions together.

The report focuses on the common domain, the mobile domain branch, and the allocation of responsibility for arcs in that subtree. It also shows how the mobile domain is divided into GSM Network, GSM Access, GSM Operations and Maintenance, and GSM Messaging, with the detailed structure of several branches handled elsewhere.

The document is organized into:

• Foreword and Introduction
• Clause 1 Scope
• Clause 2 References
• Clause 3 Definitions
• Clause 4 Symbols and abbreviations
• Clause 5 Structure of mobile domain, with 5.1 Tree structure and 5.2 ASN.1 description
• History

What are the key requirements of SIST-TP ETSI/ETR 091 E1:2005?

SIST-TP ETSI/ETR 091 E1:2005 mainly sets out how the mobile domain is named and organized. In practice, it tells standards writers where mobile-related protocol objects belong in the ETSI object identifier tree and which bodies control the different branches.

• Clause 5.1 places the mobile domain under the ETSI common domain arc and shows the path used for the mobile branch. This matters because object identifiers must be allocated in the right part of the tree to stay consistent across ETSI specifications.
• Clause 5.1 divides the mobile domain into GSM Network, GSM Access, GSM Operations and Maintenance, and GSM Messaging. That split helps authors know which branch to use for a given GSM-related function.
• Clause 5.1 states that the mobile domain spans the work of SPS and SMG. For implementers, this means the identifier tree reflects committee responsibility, not just technical topic names.
• Figure 1 identifies the designated authorities for assigning arcs and uses GSM Network as the worked example. The note says the structure below GSM Network is only an example, so readers should not copy it to other branches.
• Clause 5.2 gives an ASN.1 module, MobileDomainDefinitions, for the mobile domain. This is the machine-readable part that supports consistent implementation in specifications and tools.
• Clause 5.2 defines the mobile domain identifier and the subdomain identifiers for GSM Network, GSM Access, GSM Operation and Maintenance, and GSM Messaging. In practice, these are the named object identifiers that other documents reference.
• Clause 5.2 also defines common component identifiers for Application Context, Abstract Syntax, Application Service Element, module, and encoding rules. This provides a shared naming pattern for structuring subdomains.
• The references connect the structure to the ETSI object identifier rules and to example GSM usage in Mobile Application Part and Mobile Radio Interface - Layer 3. That helps readers see how the tree is applied in real specifications.

What terms does SIST-TP ETSI/ETR 091 E1:2005 define?

SIST-TP ETSI/ETR 091 E1:2005 defines a small set of terms and abbreviations used to describe the identifier tree.

• Common domain - a set of objects that belong to the definition of a protocol or a set of related protocols.
• GSM - Groupe Speciale Mobile.
• SMG - Special Mobile Group.
• SPS - Signalling Protocols and Switching.
• TC - Technical Committee.
• Application Context (AC) - the protocol context label used in the ASN.1 structure.
• Application Service Element (ASE) - the service-element label used in the tree structure.

Who uses SIST-TP ETSI/ETR 091 E1:2005?

SIST-TP ETSI/ETR 091 E1:2005 is used by ETSI technical committees, especially SPS and SMG, and by people drafting GSM-related specifications. Standards editors, protocol architects, and telecom engineers use it when assigning object identifiers, defining protocol objects, and keeping naming consistent across related documents.

What changed in SIST-TP ETSI/ETR 091 E1:2005 from the previous edition?

SIST-TP ETSI/ETR 091 E1:2005 is identified as identical to ETR 091 Edition 1. The document history records the first edition in July 1993 and a later conversion to PDF in February 1996.

Which standards are used with SIST-TP ETSI/ETR 091 E1:2005?

SIST-TP ETSI/ETR 091 E1:2005 relies on ETS 300 351 for the rules and registration procedures of the ETSI object identifier tree. It also cites ETSI-GSM TS 09.02 for Mobile Application Part material and ETSI-GSM TS 04.08 for Mobile Radio Interface - Layer 3 material, both used as examples of GSM Network and GSM Access usage.

What does the SIST-TP ETSI/ETR 091 E1:2005 document contain?

SIST-TP ETSI/ETR 091 E1:2005 contains a tree diagram showing the common domain and mobile domain branches, including the allocation of responsibility for the subtree. It also contains an ASN.1 module, MobileDomainDefinitions, which formalizes the object identifiers for the mobile domain and its GSM subdomains.

The document is centered on identifier structure rather than procedures or tests. Its main value is the combination of a graphical view and a formal ASN.1 definition that can be reused in protocol documentation, design work, and registration of ETSI object identifiers.
