Definitions of terms used for identifiers (names, numbers, addresses and other identifiers) for public telecommunication services and networks in the E-series Recommendations
|Publication Date:||1 November 2009|
This Recommendation provides terms and definitions for use in the field of identifiers (e.g. names, numbers, addresses and other identifiers (IDs)) for public telecommunication services and networks. The purpose of this set of definitions is to aid in the understanding of different IDs used in different telecommunications networks and related Recommendations. Consistent terminology is seen as an important factor in ITU-T Recommendations especially in Recommendations having some form of regulatory implications. For the area covering Identifiers there are important Recommendations in the E-/F-series, but also in the Q- and X-series. The E-/F-series recommendations falls under the responsibility of SG2 and Q-series lay under SG11, and SG13 covers the X-series Recommendations.
These terms and definitions have been developed, for the most part, from the practice of the use of IDs in traditional telephone networks such as PSTN, ISDN and PLMN based networks (e.g. 1G and 2G).
These terms will continue to be applicable with their current definitions for other telecommunications networks like NGNs, 3G based PLMNs and other IP based networks.
Alternatives for the preferred terms are given following a semi-colon.
The listings of the terms contains the following:
• Definition of terms for different types of plans (clause 3)
• Definition of generic terms for resources used in the plans (clause 4)
• Definition of terms for specific resources used in the plans (clause 4)
• Definition of terms for the structure and sub-parts of specific resources (clause 5)
• Definition of terms concerning administrative aspects for plans and resources (clause 6)
Every time a new Recommendation within the E-series is developed or an existing Recommendation is modified or deleted, this Recommendation shall be reviewed accordingly to ensure the information is accurate and up to date
