Work summary – Study items

Progress since last SA: FS_MCCI - Study on Mission Critical Communication Interworking between LTE and non-LTE Systems Study item initially approved at SA#72 (latest version of SID in SP-160881). Progress since last SA: It was decided that remaining work on key management would be progressed as part of normative work. Study item is now 100% complete.

FS_FRMCS_ARCH - Study on Application Architecture for the Future Railway Mobile Communication System (stage 2) Study item approved at SA#75 (SP-160269). Progress since last SA: Study re-scoped as per stage 1 status for Rel-15, i.e. to limit to multi-talker control and functional alias(es) features. Further progressed gap analysis. The work previously done on other features which are not part of Rel-15 was moved to an annex for future work beyond Rel-15. Worked on the mapping between stage 1 requirements and available solutions. Introduced 5 solutions for multi-talker control and 5 solutions for functional alias(es). Progressed solutions evaluation. Derived conclusion for multi-talker control. Study item and TR 23.790 are now 75% complete. TR 23.790 v1.0.0 is presented for information in SP-170754. Next steps: The architecture options for supporting functional alias need to be evaluated and a way forward needs to be agreed.

FS_CAPIF - Study on Common API Framework for 3GPP Northbound APIs Study item initially approved at SA#75 (latest version of SID in SP-160405). Progress since last SA: Introduced key issue for CAPIF support for service APIs from multiple providers. Agreed requirements related to security, logging, charging, service APIs from the 3rd party API providers and reference points. Further worked on the high level functional architecture for CAPIF and on deployment options (e.g. to allow service APIs from 3rd party API providers). Introduced solutions for publish, onboarding, authentication, authorization, secure communication, logging, auditing, charging, monitoring, access control. Further progressed analysis of OMA API and ETSI MEC API framework. Clarified CAPIF relationship with 3GPP functionalities. Completed evaluation for all solutions and derived conclusions for the study. Study item and TR 23.722 are now 100% complete. TR 23.722 v1.0.0 is presented for approval in SP-170755. The identification of common northbound API development guidelines have not been addressed during the study, and will be progressed during the normative phase.

FS_MBMSAPI_MC - Study on MBMS APIs for Mission Critical Services Study item approved at SA#76 (SP-170598). Progress since last SA: Approved scope and skeleton for draft TR 23.792. Several key issue descriptions were added, for announcement handling, ROHC and FEC handling, feedback on MBMS reception, API for file distribution over MBMS and registration. 1 functional requirement was derived for registration. Study item and TR 23.792 are 10% complete. Next steps: Progress key issues and gaps analysis. Progress requirements and client reference model.
