Draft Details
The present document defines the Service Stratum for the Future Railway Mobile Communications System (FRMCS).
In general, the FRMCS Service Stratum provides communication service and corresponding complementary service
resulting from 3GPP Mission Critical Services (MCX) and 3GPP multimedia system.
While FRMCS is defined in various FRMCS ETSI Technical Specifications, the present document determines
necessary components of the FRMCS Service Stratum, encompassing:
• Building blocks and corresponding reference points of 3GPP MCX/IMS.
• Reference points between MC systems/IMS for interconnection and unilateral use by MC organizations
(MC migration).
• Reference points between the MC system/IMS and external systems.
• QoS and priority management.
• User identification, authentication and authorization for the use of the FRMCS service stratum.
• Communication security aspects.
• Complementary and auxiliary service, e.g. alternative user addressing schemes.
