[{"name":"R5-201486","title":"Discussion on handling multi PDUs and PDNs","source":"Samsung","contact":"Stoyan Baev","contact-id":2367,"tdoctype":"discussion","for":"Discussion","abstract":"RAN5 decided few meetings back to introduce provisions to allow the 5G test specifications to handle multiple, i.e. unrestricted number of, PDUs establishments in order not to impose requirements on the UE to be pre-configured for testing purposes to operate not as it may operate in real life. These provisions however are not comprehensive enough to handle different UE configurations.\nFurthermore, no provisions have been introduced to handle multiple, i.e. unrestricted number of, PDNs establishments when a 5GS and EPS capable UE moves between the two systems (i.e. between S1 and N1 modes). This resulting in requiring such a UE, although being allowed full freedom to establish unrestricted number of PDUs in 5GS (and hence operate close to how it may operate in real life), to be pre-configured to limit its PDNs when it is in EPS (S1 mode) to max of 2 PDNs (and hence not operate as it may operate in real life).\nIt should be noted that depending on their deployment targets some UEs can of course require just 2 PDUs\/PDNs and those from the types the current 5G test spec can handle. This, as well as UE pre-configuration to require only 2 PDUs\/PDNs for test purposes, even if it may need more in real life, are the reasons why the tests are working today.\nTo allow better flexibility the present paper highlights some of the issues and outlines some possible solutions. CRs comprising the detailed changes needed for the outlined in general solutions are provided separately.","secretary_remarks":"","agenda_item_sort_order":358,"ainumber":"6.3.2.","ainame":"\tDiscussion Papers \/ Work Plan \/ TC lists","tdoc_agenda_sort_order":14860,"status":"revised","reservation_date":"2020-05-02 11:53:57","uploaded":"2020-05-08 15:48:22","revisionof":"","revisedto":"R5-202696","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_87_Electronic\/Docs\/R5-201486.zip","group":"R5","meeting":"R5-ah-38102","year":2020,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
