Specifications Per TSG Round

3GPP specifications are made available – free of charge – four times a year following the quarterly Technical Specification Group (TSG) plenary meetings. At each TSG round, specs can be:

• Newly brought under change control (i.e. at least 80% complete)
• Unchanged from their previous versions
• Revised as a result of incorporating approved Change Requests (either in existing Releases or in the latest Release)
• At Release-freeze time, upgraded to that Release with no technical change

The 3GPP Mobile Competence Centre (MCC) aims to make all Specs available following a TSG round as soon as possible. The target dates are shown in the table below. Where very many CRs have to be implemented, or very many specifications are to be produced, a further week beyond the above deadlines may be required. These dates are agreed by the TSG Chairs. Over the Christmas and New Year period, when the winter TSG round finishes shortly before the holiday period, an extra week or so is normally added to the final deadlines
