3GPP has published an overview of what has been achieved so far in the Mission Critical and also provides an outlook of what can be expected in the near future. A more detailed paper summarizing the use cases and functional aspects of Rel-13, Rel-14 and upcoming Rel-15 will be published later this year.
Mission Critical Services – Detailed List of Rel-13, Rel-14 and Rel-15 Functionalities
