[{"name":"SP-240793","title":"New WID on Monitoring of Encrypted Signalling Traffic (MonSTra)","source":"SA WG1","contact":"Alain Sultan","contact-id":10343,"tdoctype":"WID new","for":"Approval","abstract":"Justification: The current 5G system prevents continuation of the network surveillance troubleshooting capabilities carried out by MNOs. This is due to the introduction of encryption of the signalling exchanged between network functions and the different implementations of VNFs\/CNFs from vendors in the 5G network. For network operators, standard monitoring capabilities are thus essential to continue performing health check and troubleshooting of networks without additional integration costs and without the need to standardise, in 3GPP, the internals of VNFs\/CNFs. This work was triggered by the GSMA which expressed their concerns about the monitoring of encrypted signalling traffic looking for a mechanism for a copy of this traffic to be sent to a monitoring system. This concern was reflected in a Liaison Statement sent from the GSMA to 3GPP (WGs SA WG2, SA WG3 and SA WG5) explaining that the current encryption mechanism sending the information with (m)TLS prevents the operators of doing proper troubleshooting for operation and management procedures. Then in the different groups, there was a discussion about it that ended up the TSG SA plenary. Finally, a formal decision was taken by TSG SA plenary: SA WG1 should decide the needed requirements for the rest of the groups (WGs SA WG2, SA WG3, and SA WG5) to be able to start their work.","secretary_remarks":"Approved","agenda_item_sort_order":41,"ainumber":"6.2.1","ainame":"SA WG1 New Release 19 Work Item Descriptions","tdoc_agenda_sort_order":10880,"status":"approved","reservation_date":"2024-06-07 09:08:25","uploaded":"2024-06-11 09:49:21","revisionof":"","revisedto":"","release":"Rel-19","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_SA\/TSG_SA\/TSGS_104_Shanghai_2024-06\/Docs\/SP-240793.zip","group":"SP","meeting":"SP-104","year":2024,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
