3GPP TR 21.900 version 11.1.0 Release 11

1 Scope

This document outlines the working methods to be used by the 3GPP Technical Specification Groups and their Working

Groups and their Sub-Groups, and by the 3GPP Support Team in relation to document management, i.e. handling of

specifications, updating procedures, Change Request procedures, version control mechanisms, specifications status

information etc. It complements the rules and procedures defined for 3GPP. This document does not stipulate the details

of the internal working of the TSG Sub-Groups. From the Technical Specification Group point of view, a task and

responsibility is given to a Working Group directly answering to the Technical Specification Group. In practice, the

work/task may be carried out in a subgroup of that Working Group.

1A References

The following documents contain provisions which, through reference in this text, constitute provisions of the present

document.

• References are either specific (identified by date of publication, edition number, version number, etc.) or

non-specific.

• For a specific reference, subsequent revisions do not apply.

• For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including

a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same

Release as the present document.

ISDN and network capabilities of an ISDN".

2 Definitions and abbreviations

For the purposes of the present document, the following terms and those in 3GPP TR 21.905 apply.

building block: sub-division of a feature, representing a coherent set of technical functionality which would generally

be expected to reside in a single system element.

change control: procedure whereby proposed modifications to a specification are presented for approval to the TSG as

formal Change Requests.

closed: specification status in which no changes of any kind to the specification are permitted.

Change Request (CR): formal proposal presented on a standard form to modify a specification which is under change

control.

draft: specification status prior to change control, in which changes may be made without formal Change Requests.

early implementation: implementation of a particular feature on a platform of a release earlier than the release that

contains the feature.

feature: new or substantially enhanced functionality which represents added value to the existing system.

frozen: specification status in which only essential corrections are permitted.

Group: TSG or TSG Sub-Group.

ETSI TR 121 900 V11.1.0 (2014

09)

3GPP TR 21.900 version 11.1.0 Release 11

major version: For version x.y.z of a specification, x is called the major version.

Example: For version 3.2.0 of a specification, the major version is 3.

specification: generic term standing for Technical Specification and Technical Report.

Study Item: type of Work Item which will conduct feasibility studies and will result in a Technical Report

TSG: Technical Specification Group.

TSG change control: specification status in which the Technical Specification Group is responsible for approval of

Change Requests.

TSG Sub-Group: Working Group or subgroup of a Working Group or of a Sub-Group.

Working Group (WG): official subgroup of a TSG reporting to that TSG.

WG Change Control: specification status in which the Working Group is responsible for agreeing Change Requests

for submission to the TSG for approval.

version: unique identifier in the form x.y.z for a specification at a given point in time.

Example: version 3.12.3.

withdrawn: specification status in which the given version of the specification no longer belongs to the appropriate set

of valid specifications.

Work Item (WI): description of an enhancement to a technical area, which may be categorized as Study Item, Feature,

Building Block or Work Task.

Work Item description (WID): description of a Work Item in a standard Work Item Description sheet.

work task: sub-division of a building block, representing a self-contained, well-scoped and well-scheduled item of

work.

3 General responsibilities of the Support Team

3.1 Specifications, meetings and liaisons

The Support Team is responsible for the management of the work of the TSGs. This includes editorship and

management of specifications once they have been put under TSG change control. It also includes preparation of and

support for the meetings (including meeting reports) of the TSGs and their Working Groups, and subgroups in

descending priority.

It furthermore includes liaison with other bodies and relevant groups and institutions.

3.2 Registration of code points

In the course of 3GPP's work, it will from time to time be necessary to register code points in protocols maintained by

bodies other than 3GPP, for example, Multipurpose Internet Mail Extensions (MIME) types registered with the Internet

Assigned Numbers Authority (IANA, http://www.iana.org/

Wherever possible, registration of such code points shall be entrusted to the 3GPP Support Team rather than being

performed by an individual delegate. Since 3GPP is not a legally constituted entity, the Support Team shall register

such code points in the name of one of the Organizational Partners on behalf of all the Organizational Partners of 3GPP.
