In
38、troduction The present document provides a summary of the Release 14 Features and other significant Work Items for which a summary has been agreed to be provided. There is one clause per Feature. Each clauses begins with a table providing references that can be used to get further information, as de
39、scribed in clause 4. This table is then followed by a summary of what the feature does and how it does it. The summaries are based inputs from the Rapporteur, provided as tdoc number to the plenary. The tdoc number where the original version of the summary can be found is provided in the first sente
40、nce of each clause. ETSI ETSI TR 121 914 V14.0.0 (2018-06)73GPP TR 21.914 version 14.0.0 Release 141 Scope The present document provides a summary of each Feature or, whenever needed, of each significant Work Item, introduced in Release 14. The information provided in the present document is limited
41、 to an overview of each feature, explaining, in about a page, its purpose and the main lines of its behaviour. The next step to retrieve more information on a given feature is to consult the 3GPP Ultimate web site, as explained in Clause 4. This document presents the “initial state“ of the Features
42、introduced in Release 14, i.e. as they are by the time of publication of this document. It is however important to note that each Feature is subject to be later modified or enhanced, over several years, by the means of Change Requests (CRs) associated to the Feature or to “TEI“ (Technical Enhancemen
43、ts and Improvements). It is therefore recommended to retrieve all the CRs which relate to the given Feature, as explained in Clause 4, to further outline a feature at a given time. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of
44、 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
45、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. 1 3GPP TR 21.905: “Vocabulary for 3GPP Specifications“. Note: Due to the specificity of the present document, consisting in a col
46、lection of independent summaries, the references are given at the end of each clause rather than in this clause. 3 Definitions, symbols and abbreviations 3.1 Definitions For the purposes of the present document, the terms and definitions given in 3GPP TR 21.905 1 and the following apply. A term defi
47、ned in the present document takes precedence over the definition of the same term, if any, in 3GPP TR 21.905 1. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in 3GPP TR 21.905 1 and the following apply. An abbreviation defined in the present document takes prece
48、dence over the definition of the same abbreviation, if any, in 3GPP TR 21.905 1. Abbreviations specific to a given clause are provided in the clause they appear.

49、ntroduction Since the present document is limited to provide an overview of each Feature, this chapter explains how to get additional information, in particular how to retrieve all the Specifications (TSs) and Reports (TRs) as well as all the CRs which relate to a given Work Item. The Unique Identifier (UID) is the key to get additional information on a given Work Item. It can be found in the table located just below the clauses header. The table has the following format: Table 4.1-1: table format Unique Identifier (UID) Name Acronym g75g437g410g367g349g374g286g3g62
