However, GCF cannot apply stronger certification criteria than outlined in the related 3GPP standards. In order to fully abandon use of insecure ciphering algorithms, GCF would like to request 3GPP SA WG3 to explicitly prohibit support of GEA1 in all releases of TS 43.020.\nGCF also recommends 3GPP SA WG3 to consider phasing out of GEA2 in a similar way.\nGCF will then adapt their certification criteria accordingly.\nActions: 3GPP is kindly asked to discuss above mentioned recommendations and feed back to GCF.","secretary_remarks":"","agenda_item_sort_order":4,"ainumber":"3","ainame":"\tIncoming Liaison Statements","tdoc_agenda_sort_order":150,"status":"noted","reservation_date":"2021-12-26 09:51:28","uploaded":"2021-12-26 09:55:29","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"TSG WG SA3","Cc":"TSG WG RAN5, PTCRB, PVG","lsoriginalls":"S-21-245r2_LS to 3GPP SA3 on nonsupport of GEA1","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_94_Electronic\/Docs\/R5-220015.zip","group":"R5","meeting":"R5-94-e","year":2022,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

For instance, TSG SA has undertaken studies at TSG SA level and in some of its WGs. Similarly, TSG RAN has addressed the topic quite extensively in various studies and is also soon engaging in additional work on the subject in Rel-18. \nThe EE-specific efforts so far undertaken e.g., in SA5 have aimed mostly at improving the energy efficiency by impacting the operations of the system. As we now are starting to specify the 5G-Advanced features, TSG SA kindly requests the recipient WGs and TSGs to consider EE even more as a guiding principle when developing new solutions and evolving the 3GPP systems specification, in addition to the other established principles of 3GPP system design.\nTSG SA clarifies that in addition to EE, other system level criteria shall continue to be met (i.e.  the energy efficiency aspects of a solution defined in 3GPP is not to be interpreted to take priority or to be alternative to security, privacy, complexity etc. and to meeting the requirements and performance targets of the specific feature(s) the solution addresses). \nThis guiding principle complements the continued importance  of work specifically dedicated to Energy efficiency (e.g., work aiming at improving the energy efficiency by impacting the operations of the system, as for instance work in [1],[2],[3],[4]).\nACTION: \t3GPP SA kindly requests to take the above principles into consideration.","secretary_remarks":"","agenda_item_sort_order":4,"ainumber":"3","ainame":"\tIncoming Liaison Statements","tdoc_agenda_sort_order":170,"status":"noted","reservation_date":"2021-12-26 09:51:28","uploaded":"2021-12-26 09:55:29","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"TSG RAN, TSG CT, TSG SA WG1, TSG SA WG2, TSG SA WG3, TSG SA WG4, TSG SA WG5, TSG SA WG6, TSG RAN WG1, TSG RAN WG2, TSG RAN WG3, TSG RAN WG4, TSG RAN WG5, TSG CT WG1, TSG CT WG3, TSG CT WG4, TSG CT WG6","Cc":"","lsoriginalls":"SP-211621","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_94_Electronic\/Docs\/R5-220017.zip","group":"R5","meeting":"R5-94-e","year":2022,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
