Qualification of
3GPP:
|
|
|
The qualification analysis of TSDSI with a goal to allow the ITU-T A.5 qualification for 3GPP was requested by SG15 in the January/February 2020 meeting (see TD527/P, https://www.itu.int/md/meetingdoc.asp?lang=en&parent=T17-SG15-200127-TD-PLEN-0527). This is based on the section 7.3 of the ITU-T A.5 (09/2019) which states that "For the case of a proposed referenced document jointly owned by multiple organizations in a partnership project that is not a legal entity, the partnership project is considered to be qualified according to the criteria in Annex B if each organization is itself qualified according to the criteria in Annex B". The only 3GPP partner not previously A.5 qualified was TSDSI.
Based on the information available at the time of the SG15 plenary on 18 September 2020 (see TD635/P,https://www.itu.int/md/meetingdoc.asp?lang=en&parent=T17-SG15-200907-TD-PLEN-0635), SG15 approved the A.5 qualification for TSDSI, and by extension, SG15 also approved the A.5 qualification for 3GPP, as reported in SG15-R24 (https://www.itu.int/md/T17-SG15-R-0024/en).
