Some of these slides assume a particular version of MS-Word © is being used. Employ common sense in interpretation.

Note 2:

These guidelines cannot cover every eventuality likely to be encountered in the conversion process. If in doubt, consult me (or Mo); we might not have the correct answer, but at least we should end up with a consistent approach, and I will try to incorporate commonly encountered problems in this guide.

Note 3:

These guidelines were written to cover the conversion of pre-Release-4 specs to Release-4. With a little care, they can also be employed when converting earlier releases of the GSM specs to the 3GPP format. The only real difference is that the spec number retains its old aa.bb format rather than the new aa.0bb format.



5

Open a copy of the master skeleton document.


Stop press:Latest

terminology is“3GPP TS”

or“3GPP TR”

here, and throughout the

document.


6

Ensure it is associated with the 3GPP template, but that the "automatically update document styles" checkbox is cleared (not checked).

[Tools | Templates]



7

Save it with file name according to the spec number and version.

[File | Save as]



8

Set its file properties appropriately.

[File | Properties]



9

Open the "old style” GSM specification.

(You may find it better to have tiled windows for easier movement between the documents.)



10

Manually insert the correct details on the cover page (spec number in new format and version, date, TSG full name [refer to database record] in second line of title, main part of title, Release id. Take care not to damage the special fields using styles which are propagated in the page headers throughout the document (top line of page and Release line of title).



11

Copy the GSM logo and paste it into the new doc to the left of the 3GPP logo.



RStop Press:

The GSM logo may have been added to the

skeleton by the time you read this. In any case, it should be placed against

the left margin.(Use a left-justified paragraph and insert a right-handed tab at the far right margin; insert a tab between the GSM and 3GPP

logos)..


12

Page 2: Manually insert the correct keywords, using the source GSM document and/or its WPM record as a basis.

Despite what may appear on the original GSM document, only the keywords listed in WPM are permitted!

WARNING!

Many GSM specs have non-standard structure. The structure of the original specs must be preserved; the following instructions should therefore be adapted to the circumstances of each individual spec.



14

Introduction: Manually copy and paste the text from the original into the new. If there is none, delete the Introduction header in the new.

Delete the blue instructional text from the new.



15

IPR statement: do NOT copy the IPR statement into the new document.



16

Scope: Copy the scope clause from old to new docs.



17

References: Delete the example references from the new. Copy the individual references from old to new. Do not copy the introductory text at the top of the References clause.


At the time of writing, consideration is being given to retaining the bullet point clarifying

that unspecific references should be

taken to refer to specifications of the

same Release.


18

Definitions, symbols and abbreviations: Delete the example text and the blue guidance text from the new doc. Copy the individual entries from old to new documents, preserving the introductory text. Delete any subclauses not used, and adapt clause title and subclause header numbering accordingly.



19

In the new doc, delete the text starting at clause 4 up to and including the header and blue text of annex <X> (Change history). That is, leave only the change history table itself.



20

From the old document, select and copy all the body of the text (normally starting at clause 4) to the end of the change history table. Do NOT include the ETSI History table on the last page. Paste this into the new document immediately above the Change history table.



21

In the (initially empty) Change history table from the new doc skeleton, which should be at the very end of the new doc, fill in the first line indicating the date, as subject "Conversion to 3GPP layout and number.", and indicate in the "old" column the original GSM spec number and version; and in the new the resulting new spec number and version.


You will need to reduce the font size of

the spec number (only) to avoid an

unwanted line break.


22

Note to previous slide:

If you are dealing with a pre-Release-4 spec, you can simply retain the existing change history table and add the new line(s) justifying the change in the usual way.



23

Check the references:In the references clause and throughout the new document, change the number format of all referenced GSM specifications into the new format: e.g. change GSM 03.09 into 3G TS 43.009.


3GPP TS now, of course!


24

Check for references found in the body of the text but not listed in the References clause, and add them to the list.



25

Check that all references listed in the References clause are actually mentioned in the body of the spec. Eliminate those which are not (leave the entry in the list, but replace the identity of the referenced document with "(void)”).

(Do not re-use the entries for new references, which must always be appended to the end of the list.)



26

Read the text of the new document, and do any necessary editorial updates required as a result of the transfer of ownership.

(For example, change any references to TC SMG to 3GPP TSG x. Also, change "this EN" into "the present document", etc.)



27

Check that no undesirable formatting changes have occurred; this can only be effectively done by a visual on-screen comparison between old and new docs.

Use page layout view to check against unexpected page breaks and damaged headers.



28

Select the "Apple LaserWriter Pro 630" printer driver to ensure correct pagination.

29

Update the Table of Contents (using the MCC macro).



30

Save the new document and close it.

That’s all folks !
