[{"name":"R5-198462","title":"Proposing new IMS test cases","source":"DOCOMO Communications Lab.","contact":"Takao Suzuki","contact-id":75437,"tdoctype":"discussion","for":"Endorsement","abstract":"The purpose of this document is to discuss about adding the following 4 TCs for IMS. \nTC1: Emergency call with emergency registration \/ Abnormal case \/ IM CN sends a 503 \/ UE performs emergency call via CS domain \/ UTRAN or GERAN\nTC2: Mobile Originating SMS \/ RP-ERROR\nTC3: MO MTSI Video call \/ MO UE cancels call establishment\nTC4: Initial registration \/ Abnormal case \/ IM CN sends a 305 \/ new P-CSCF Discovery via PCO (IPv6)\n2.\tDiscussion\n?\tTC1: Emergency call with emergency registration \/ Abnormal case \/ IM CN sends a 503 \/ UE performs emergency call via CS domain \/ UTRAN or GERAN\nAccording to TS 24.229 [1], when the UE receives a 3xx (other than 380), 4xx, 5xx or 6xx response to an INVITE request for IMS emergency call establishment, the UE shall perform domain selection and reattempt the emergency call via the selected domain. This behaviour can happen in the real NW, but there is no test case to check it.\nProposal 1: RAN5 needs to add TC1 in TS 34.229-1. TC1 is applied to IMS capable UEs from Rel.9.\n?\tTC2: Mobile Originating SMS \/ RP-ERROR\nWhen the UE sends a MO SMS, there is a case that the UE receives RP-ERROR. This behaviour can happen in the real NW, but there is no test case to check it.\nProposal 2: RAN5 needs to add TC2 in TS 34.229-1. TC2 is applied to IMS capable UEs from Rel.8.\n?\tTC3: MO MTSI Video call \/ MO UE cancels call establishment\nWhen MO UE cancels the establishment of video call, it sends SIP_CANCEL to MT UE.  This behaviour can happen in the real NW, but there is no test case to check it. \nProposal 3: RAN5 needs to add TC3 in TS 34.229-1. TC3 is applied to IMS capable UEs from Rel.8.\n?\tTC4: Initial registration \/ Abnormal case \/ IM CN sends a 305 \/ new P-CSCF Discovery via PCO (IPv6)\nAccording to TS 24.229 [1], if the UE configured to discover P-CSCF address via PCO receives SIP_305 Use Proxy and then has no available P-CSCF address, the UE shall perform a new P-CSCF discovery procedure and initiate the SIP registration procedure again. This behaviour can happen in the real NW, but there is no test case to check it. \nProposal 4: RAN5 needs to add TC4 in TS 34.229-1. TC4 is applied to IMS capable UEs from Rel.8.\n3.\tProposal\nProposal 1: RAN5 needs to add TC1 in TS 34.229-1.
