Identify key issues, develop corresponding architecture requirements and potential enhancements to the architecture as required, based on: a. elaborate support for roaming i.e. access to edge computing services by UEs that are attached to PLMN networks other than their home networks; b. federation of services across ECSPs i.e. access to edge computing services via an ECSP different from the one to which the UE is associated; c. service continuity support across MNOs and ECSPs, with support for roaming and federation scenarios; d. new or enhancement to EEL capabilities and related APIs to support high performance of EAS; e. application context relocation (ACR) between EAS and cloud Application Servers; f. specification of EDGE-5 interface between the AC and the EEC; g. a framework to enable and manage EEL service differentiation; h. enhancements and optimizations of existing features (e.g. efficient communication for constrained devices like discovery bypass, push notification support, dynamic EAS instantiation), which were not completed in Rel-17; i. co-existence of network and application layer architecture solutions for Edge Computing e.g. discovery; and j. alignment with ETSI MEC and GSMA OP architectures; 2. Identify potential solutions as required, including the information flows and the APIs satisfying the architecture requirements, enhancements and alignment aspects identified in 1); 3. Identify new edge enabler layer models considering the enhancements identified in 2); and 4. Identify potential alignment of any northbound API definitions (e.g. direct network capability exposure, Edge application server enablement, SCEF\/NEF\/SCEF+NEF APIs) with CAPIF (TS 23.222) and related enhancements. NOTE: The split of responsibilities between SA WGs to harmonize with ETSI MEC and GSMA OP architectures require alignment in SA.","secretary_remarks":"CC#3: Block Approved","agenda_item_sort_order":40,"ainumber":"6.6","ainame":"Revised Release 18 Study Item Descriptions and Work Item Descriptions","tdoc_agenda_sort_order":11490,"status":"approved","reservation_date":"2021-09-07 09:04:13","uploaded":"2021-09-08 16:22:11","revisionof":"","revisedto":"","release":"Rel-18","crspec":"","crspecversion":"","workitem":[{"winame":"FS_eEDGEAPP"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_sa\/TSG_SA\/TSGS_93E_Electronic_2021_09\/Docs\/SP-210951.zip","group":"SP","meeting":"SP-93-e","year":2021,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

The focus is on the following: 1. Connectivity related optimizations: a. between MC service systems (signaling and media) b. between MC service organizations (signaling and media) 2. Functional alias related aspects: a. use of functional alias in one MC service system (organization) allocated by the home MC system (organization) b. use of functional alias via multiple MC service systems (organizations) allocated by the home MC system (organization) c. functional alias activation\/deactivation when the MC service user is in a different MC system or MC organization d. transfer\/retrieval of functional alias binding for MC service groups when using a functional alias over multiple MC service systems or MC organizations 3. Call forwarding\/call transfer related aspects: a. call forwarding to users in a different MC service system (organization) b. call transfer to involving users in a different MC service system (organization) 4. IP connectivity and SDS related aspects: a. point-to point (standalone) that involves two MC service systems (organizations) case 1: MC service user is abroad and shall use home breakout case 2: MC service user is in the home MC system (organization) and shall use local breakout b. group standalone that involves two MC service systems (organizations) case 1: MC service user is abroad and shall use home breakout case 2: MC service user is in the home MC system (organization) and shall use local breakout 5. Group communication related aspects: a. groups that are spread of multiple MC systems (organizations) that also involves MC system (organization) relocation during the group communication (actual use case in border areas) b. security implications when MC service users are involved that belong to different MC service systems (organizations) 6.

This objective includes: - Identify subclauses in the existing stage 2 Mission Critical specifications that should also apply to the 5GS, but which currently contain 4G specific terminology and therefore would require terminology changes. - Develop a common approach (e.g. terminology) for changes in stage 2 Mission Critical specifications that apply to the 5GS. - Review and identify the 5GS aspects (e.g. 5QI, network slicing) to support Mission Critical architecture. - Identify key issues and develop solutions to ensure support of Mission Critical services over 5GS. - Evaluate the solutions and make recommendations for normative work. - Study where and how to integrate solutions in stage 2 Mission Critical specifications, either in the existing specifications or in a new specification.
