[{"name":"R5-193558","title":"Issue seen in Multi-PDN configuration with Internet as secondary PDN","source":"Qualcomm Incorporated, Keysight Technologies Ltd.","contact":"Ankit Banaudha","contact-id":58157,"tdoctype":"discussion","for":"Endorsement","abstract":"Currently major suite of test cases are tested with Multi-PDN configuration. The purpose of this paper is to discuss and highlight the problem seen recently when IMS PDN is primary and Internet is secondary in Multi-PDN configuration.\n2.\tDiscussion\nBelow is the PICS setting for configuring IMS PDN as primary and Internet PDN as secondary in Multi-PDN configuration:\n\u2022\tpc_IMS = TRUE \n\u2022\tpc_Provide_IMS_as_second_APN = FALSE \n\u2022\tpc_Provide_Internet_as_second_APN = TRUE\nWith IMS PDN as primary and Internt PDN as secondary, below are the two possible sub-configurations:\na)\tWhen Mobile Data is on:\nUE will complete attach procedure with IMS as primary PDN and will autonomously initiate PDN connectivity request with \u201cInternet\u201d PDN successfully. There is a possibility that UE will send Service Request message (RRC connection request with \"mo-data\") due to other APNs and background applications that would like to connect to the internet. This will result in the test case failure as there is no support in the Prose\/TTCN to handle additional Service Request messages given the number of APNs and background applications trying to access internet is not known. This is the issue we are seeing when executing major suite of [1] and [2] test cases.\nb)\tWhen Mobile Data is off:\nUE will complete attach procedure with IMS PDN as primary and will not initiate PDN connectivity request (for Internet PDN). This will cause failure due to test case timeout as SS is expecting PDN connectivity request from UE for the Internet PDN as the test case is set to be executed in Multi-PDN configuration. Currently there is no trigger handled in the Prose\/TTCN for a SS pop-up for initiating the secondary PDN.\n3.     Proposal\nBased on section 2 discussion details, it seems reasonable to test with UE which has mobile data as off for the Multi-PDN configuration with IMS as primary and Internet secondary as we cannot handle more than two PDNs and unexpected requests from UEs based on the background applications that would like to connect to the internet as described in section 2.a.\nTo be able to test with Mobile data off, there is a need for IXIT parameter for TTCN to trigger a MMI pop-up for initiating secondary PDN connection.\n1)\tA Prose CR [4] has been raised to introduce a new IXIT px_mobile_data. \n2)\tA Prose CR [3] has been raised to updated the generic procedure 4.5A.16.3.","secretary_remarks":"","agenda_item_sort_order":488,"ainumber":"6.4.6","ainame":"\tDiscussion Papers \/Work Plan \/ TC lists","tdoc_agenda_sort_order":35580,"status":"noted","reservation_date":"2019-04-23 09:45:28","uploaded":"2019-05-03 16:28:01","revisionof":"","revisedto":"","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_83_Reno\/Docs\/R5-193558.zip","group":"R5","meeting":"R5-83","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
