The Handling of many 3GPP specifications could be complex and a timeconsuming procedure. The ongoing standardization and different release versions are leading to frequent updates of the specification documents. The following tools might be helpful and are free to use.

The scripts are written in python. Version 3.5 or more up to date is needed. The scripts were implemented under Microsoft Windows 10 and Linux Mint 18.3, respectively, and if you want using the toolset in a comprised way, you also need Microsoft Word and Excel (LibreOffice when using Linux). Several python packages are needed as well. You can use the python package index (pip) for installing the needed packages under Windows as follows:

pip install pywin32 openpyxl lxml requests pypdf2 bibtexparser python-docx

Infos regarding to python and the pip you'll find here: https://www.python.org/ or https://pypi.org/. Important: openpyxl version 2.5.10 is needed, higher versions might cause errors. All scripts have been tested with following versions of the other python packages: lxml 4.2.5, requests 2.20.1, pypdf2 1.26.0, bibtexparser 1.0.1, python-docx 0.8.10

• First of all, visit the 3GPP Portal via https://portal.3gpp.org/ and choose the tab Specifications.
• Fill out the corresponding fields for searching the specifications you are interested in. For example, we search for all specifications of the series 38.
• More than one hundred specifications will be found. You can download each specification by clicking on the glasses-button first. A popup window will appear. Under the tab Versions you are able to download the specification by clicking the individual version-number. A download-window will appear which allows you to save the specification as zip-file. Within the zip-file will be in the most cases a single Word-doc-file.
• The previous point has shown, that this could be very costly, especially if you want to download many specifications.
• The common approach using this script is to download the excelfile by clicking on the excel-icon-button in the upper right corner.
• Save the excelfile in the same folder as this script. Name the downloaded excelfile as LATEST-EXCELFILE.xlsx.
• Make a copy of the downloaded excelfile. Name this copy of the excelfile REFERENCE-EXCELFILE.xlsx. You should reuse the REFERENCE-EXCELFILE.xlsx for any further runs of this script. The REFERENCE-EXCELFILE.xlsx is maintained automatically by the script. If you want to know whether there are new versions of specifications available you just have do download the LATEST-EXCELFILE.xlsx as mentioned above.
• Then run this script as follows:

python specificationsHandler.py [ LATEST-EXCELFILE.xlsx ] REFERENCE-EXCELFILE.xlsx [ -3 ] [ -w | -wx | -wxp ] [ -cl ]

• The script checks whether there is a specification in the LATEST-EXCELFILE.xlsx which is not in the REFERENCE-EXCELFILE.xlsx. If this is the case, the complete row will saved into the REFERENCE-EXCELFILE.xlsx. The script also generates new columns for the version-number and the corresponding date. These columns refer to the online data.
• Then, the specifications in the REFERENCE-EXCELFILE.xlsx are distributed over several threads. Every thread connect the individual download-site of each specification and looks up which version and date is available.
• After all threads are finished every specification version-number and date are compared with the online retrieved verion-number and date. If there is a different version and date online available than in the REFERENCE-EXCELFILE.xlsx, the newest version will be downloaded.
• All changed specifications will be downloaded. The zip-files are opened and if there is only one doc- or docx-file in it, this file will be converted to pdf and the doc- and zipfile will be deleted. Otherwise the zip-file has to be handled manually.
• If the download of the zip-file and the extracting and convertig was successful, the corresponding row of the specification in the REFERENCE-EXCELFILE.xlsx will be updated (by updating the version-number and date).
• In the last step there are a check-txt-file and a log-file generated with additional information.
• Use the REFERENCE-EXCELFILE.xlsx for following updates. The only thing you have to do is to download the LATEST-EXCELFILE.xlsx as described in the first step.
• NEW: Since version 1.3 it is possible to extract only Word-documents from the corresponding Zip-file (without conversion to pdf), if the optional parameter -w is passed. You can pass both optional parameters (-3 -w, the order does not matter) or just one of it.
• NEW: Since version 1.4 it is possible to pass the parameter -wx (instead of -w). By passing this parameter only Word-documents will be extracted AND all .doc-files will be converted to .docx-format.
• NEW: Since version 1.5 (windows only) the script docxExtracter.py is available. It allows to extract the text from the chapter scope of all docx-Specifications in the Specifications-Folder into one txt-file (counterpart of pdfExtracter.py). Furthermore, it is possible to extract the comprehensive text of all docx-files within the Specifications-Folder by passing the optional parameter -a.
• NEW: Since version 2.1 (windows only) it is possible to convert both pdf and docx files of downloaded specifications by passing the optional parameter -wxp.
• NEW: Since version 2.2 (windows only) the optional parameter -cl is introduced. By using, it is possible to extract and convert a specification even though there are more than one doc or docx-files within the zip-file. The doc(x)-file with a cl substring in its name will be chosen (the first that was found in the zipfile) and extracted and converted (an example-file would be specification 21.866 Version 1.2.1).
• NEW: Since version 3.0 (windows only) the LATEST-EXCELFILE is an optional parameter. If it is passed, the script checks, whether there are specs in the LATEST-EXCELFILE, which are not included in the REFERENCE-EXCELFILE. If that is the case, all these specs are added to the REFERENCE-EXCELFILE and considered in following runs. If the LATEST-EXCELFILE is not passed, the script only checks, whether there are any updates of the specs included in the REFERENCE-EXCELFILE available.

Attention! The converting into pdf (and docx as well) might take a while, especially when you use the script the first time and many zip-files are downloaded.

Important remark: Within the REFERENCE-EXCELFILE.xlsx there will be columns generated with name Version and Date and VersionTwo and DateTwo. The data referring to these columns is retrieved online from the individual specification site. For example, consider the specification with id 36.300 --> https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=2430. Choose the tab Versions. The versions are sorted by the release. In this case the columns Version and Date correspond to the release at the top and the latest published version, VersionTwo and DateTwo always correspond to the release which comes next to the first release. Regarding to 36.300 the latest version (and date) of release 15 and release 14 would be checked and compared to the values which are saved in the REFERENCE-EXCELFILE.xlsx. If there are newer versions available, it would be downloaded and the referring field in the column would be updated. It is also possible to check whether there is a third published release of a specification by passing the optional parameter -3.

• Be sure, there is a folder with name Specifications in the same directory as this script.
• All PDF-Files in the Specifications-Folder will be searched through and the individual scope-section will be read.
• This script uses several threads to shorten the procedure.
• After all threads are finished a textfile with name scopeOfSpecifications.txt is generated.
• In this txt-document are all scope-sections of all captured specificationdocuments saved.
• Now it is possible to do a keywordsearch within this txt-file.
• NEW: Since version 1.5 the script docxExtracter.py is available. It allows to extract the text from the chapter scope of all docx-Specifications in the Specifications-Folder into one txt-file (counterpart of pdfExtracter.py). Furthermore, it is possible to extract the comprehensive text of all docx-files within the Specifications-Folder by passing the optional parameter -a (windows only). The whole text of all considered specifications is saved into the generated txt-file textOfAllSpecifications.

python pdfExtracter.py
python docxExtracter.py [ -a ]

Important remark: In spite of the usage of several threads for extracting the scope of each pdf/docx the finishing of this script might take a while. It depends on the number of pdfs/docxs in the Specifications-Folder.

• This script extracts the specifications within the REFERENCE-ECXELFILE into a bib-file.
• With the optional parameter -i only the specifications will be extracted which are marked as important within the REFERENCE-EXCELFILE.xlsx. Important specifications can be marked within the column important in the REFERENCE-EXCELFILE.xlsx.
• Because a specific specification can have several release versions, the version-number and the corresponding date is saved into the note-field.

python specificationsToBib.py REFERENCE-EXCELFILE.xlsx OUTPUT-BIBFILE [ -i ]

• There are linux-versions of all four scripts available in the folder LINUX.
• These scripts were tested on different hardware (all running Linux Mint 18.3).
• Install the necessary packages first:

sudo apt install python3-pip
sudo apt install python3-setuptools
pip3 install openpyxl lxml requests pypdf2 bibtexparser python-docx

• Run the scripts as mentioned above with the command python3

Important: The conversion of doc-files into docx-file or pdf-files, respectively, will be done with LibreOffice (maybe you need to install LibreOffice). The converted files could have format errors. Because of that we strongly recommend using the scripts with Windows.
