B.1 General

21.9163GPPRelease 16Release descriptionTS

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 clause’s header. The table has the following format:

Table B-1: table format

Unique Identifier (UID)

Name

Acronym

Outline Level (1=Feature, 2=Building Block, 3=Work Task)

Responsible Working Group

Work Item Description

For readability reasons, the table headers are omitted in the continuation of the present document.

For instance, for the "Mission Critical Push to Talk over LTE Realignment", the table has to be understood as:

Table B-2: Example of table at the introduction of each Feature

Unique Identifier (UID)

Name

Acronym

Outline Level

Responsible Working Group

Work Item Description

700029

Mission Critical Push to Talk over LTE Realignment

MCImp-MCPTTR

2

S1

SP-150821

Thus, the UID for this Work Item is 700029.

Two methods are now possible to retrieve more information on a given feature: the "Step by step method" and the "Direct method". The "direct method" is faster but implies to know the hierarchical structure of the Work Items. The "step by step method" is slower but is easier to use, in particular when the hierarchical structure is unknown.

For instance, for retrieving all the CRs that relate to "Enhancements for Mission Critical Push To Talk", the search has to be done on UID 740022 but also potentially on its children Work Items (UID 720056, 740023 and 740024).
