The following key issues (non exhaustive-list) will be part of the SA WG2 scope of the study item: 1) Regulatory requirements  S8HR roaming architecture needs to meet all the current regulatory requirements applicable to voice roaming, specifically: - Authenticated\/unauthenticated emergency calls shall be supported as in circuit switched voice today. - When a non UE detectable IMS Emergency call is carried, over the IMS APN, back to the HPLMN the P-CSCF (in the HPLMN) needs to be capable of deciding the subsequent action. 2) Voice call continuity - Study impacts on SRVCC for the S8HR roaming scenarios required by GSMA. 3) Coexistence of LBO and S8HR roaming architectures - An operator may need to support both LBO and S8HR roaming architecture options for VoLTE roaming with different operators, on the basis of bilateral agreement and depending on the cap","secretary_remarks":"","agenda_item_sort_order":190,"ainumber":"17","ainame":"Proposed New Study Items (SIDs)","tdoc_agenda_sort_order":11840,"status":"approved","reservation_date":"2015-06-09 16:55:57","uploaded":"2015-06-09 16:55:50","revisionof":"","revisedto":"S2-153778","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/TSG_SA\/TSGS_68\/Docs\/SP-150255.zip","group":"SP","meeting":"SP-68","year":2015,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
{"name":"SP-150310","title":"New Study Item on Overload Control for Diameter Charging Applications","source":"SA WG5","contact":"Maurice Pope","contact-id":648,"tdoctype":"SID new","for":"Decision","abstract":"Objective: The objective of this study item is to study overload control mechanisms for Rf and Ro interfaces based on the conclusion of the Study Item FS_DOCME. For 3GPP Charging Diameter interfaces, the Diameter overload control mechanism will be based on the IETF Draft 'Diameter Overload Indication Conveyance' that defines the AVPs for the transport of overload information of Diameter application as well as the basic behaviour of the Diameter endpoints receiving this information. The latest IETF version: i.e. draft-ietf-dime-ovli-08 will be considered as the reference of this SI based on the fact that the IETF draft has evolved since the TR conclusion. Whenever IETF draft beyond 08 is available before study completion, it shall be considered as the new reference of the Study Item. As per TR 29.809, the following conclusions apply and will not be studied in this study item: - How a reporting node determines it is entering into an overload condition is implementation dependen","secretary_remarks":"","agenda_item_sort_order":190,"ainumber":"17","ainame":"Proposed New Study Items (SIDs)","tdoc_agenda_sort_order":11850,"status":"approved","reservation_date":"2015-06-11 05:37:17","uploaded":"2015-06-14 11:58:48","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/TSG_SA\/TSGS_68\/Docs\/SP-150310.zip","group":"SP","meeting":"SP-68","year":2015,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
