[{"name":"SP-180736","title":"Updated SID: Study on Enhanced IMS to 5GC Integration","source":"SA WG2","contact":"Maurice Pope","contact-id":648,"tdoctype":"SID revised","for":"Approval","abstract":"Objective: The aim of this study is to investigate enhancements to the IMS architecture and capabilities to better address the new features and services of the 5GC system and to enhance how IMS FE's integrate with the new network functions of 5GC. The existing IMS architecture and characteristics are the baseline from which this investigation will study, it is not expected to propose changes to the nature of the functional split and the signalling between IMS network functions - specifically SIP signalling between the UE and IMS network, and between IMS FE's remains 'as-is' with only necessary extensions (e.g. new headers) where required.  Specific aspects of IMS\/5GC interworking that will be studied are: - In regard to 5GC network slicing; what enhancements (if any) are necessary for IMS to efficiently support devices and networks with multiple slices and different IMS services per slice? - Should (and How does) IMS leverage the 5GC's support for localized routing of traffic and place","secretary_remarks":"Approved","agenda_item_sort_order":150,"ainumber":"17B.17","ainame":"(FS_eIMS5G) - Study on Enhanced IMS to 5GC Integration","tdoc_agenda_sort_order":12150,"status":"approved","reservation_date":"2018-08-30 07:09:32","uploaded":"2018-08-30 14:17:55","revisionof":"","revisedto":"","release":"Rel-16","crspec":"","crspecversion":"","workitem":[{"winame":"FS_eIMS5G"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/TSG_SA\/TSGS_81\/Docs\/SP-180736.zip","group":"SP","meeting":"SP-81","year":2018,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
