Study on application architecture for the Future Railway Mobile Communication System (FRMCS) Phase 2
The present document captures architectural requirements to develop solutions for the Future Railway Mobile Communication System (FRMCS) to meet Rel-16 normative Stage 1 requirements.
The normative Stage 1 requirements are specified in 3GPP TS 22.280 [2], 3GPP TS 22.179 [3], 3GPP TS 22.281 [4], 3GPP TS 22.282 [5] and 3GPP TS 22.289 [6].
The study uses existing 3GPP functionality and those specified for Mission Critical Communication in normative specifications 3GPP TS 23.379 [7], 3GPP TS 23.280 [8], 3GPP TS 23.281 [9], 3GPP TS 23.282 [10] and 3GPP TS 23.283 [11] as working basis.
This document will provide recommendations for normative work.
