Scope
The present document: 1) Provides a reference model of FRMCS system architecture from a functional point of view. 2) Provides a high-level description of the functions that address FRMCS requirements (as specified by FRMCS URS and Use Cases). 3) Defines internal and external boundaries of the FRMCS system (e.g. transport versus applications@ external systems@ external networks@ etc.). 4) Defines further potential steps. The present document describes a potential high-level functional architecture@ as well as a high level grouping of FRMCS system functions and mapping towards requirements. In addition@ the present document investigates different technical possibilities@ e.g. 3GPP building blocks@ to address the requirements of the FRMCS system. Some of the currently developed techniques@ e.g. Service Based Architecture (SBA) or Software Defined Networks (SDN)@ have not been considered in the present document and might be included in a future release. Finally@ the present document identifies the next steps to ensure the complete definition of the FRMCS system.
