3GPP 23.280 - Functional model for application plane for an MC system
Here are some links in support of this figure:
Clause 7.5CSC‑1

Rapporteur:  Mr. Amogh, Niranth

This document specifies the common functional architecture, procedures and information flows needed to support mission critical services including the common services core architecture.
The present document is applicable primarily to mission critical services using E-UTRAN access based on the EPC architecture. Certain MC service functions such as dispatch and administrative functions could also be supported via non-3GPP access networks but no additional functionality is specified to support non-3GPP access.
The common functional architecture to support mission critical services can be used for public safety applications and also for general commercial applications e.g. utility companies and railways.
