Mission Critical Services
Since the early 90s, The Third Generation Partnership Program (3GPP) has set standards for wireless communications. 3GPP is the global standards body for 3G, LTE (4G) and 5G. At present, they have standardized mission-critical services that emphasis on high performance critical communications for first responders, emergency services and others in demanding field jobs.
It has all been created in order to improve interoperability and 2-way radio communications for present-day, interoperable broadband communications. The escalating requirement for video and data transmission for emergency response teams and public safety sectors arises from the demand to gain real-time video and data out of the scene and manage to transmit or broadcast straight to and from the field offices. This allows each and every unit to notice the identical situational awareness and work together as a unified entity when all pertinent visuals are available.
In 2013, The public safety departments of various countries such as Korea, USA, UK, France, Germany, Netherlands, TCCA, ETSI, ATIS, TTA sow the seeds of MC standardization. 3GPP is the home for Global Mission Critical Services (MCX) Standards and is recognized all over the world. Over 600 user demands were created with the help of inputs and feedbacks from the mobile broadband industry. In the year 2016, The Third Generation Partnership Program (3GPP), set foot in the application domain by standardizing Mission Critical Push to Talk (MCPTT) in Rel-13. To provide organizational support along with focus on a new working group - SA6 - was introduced in order to complete the new application related work in addition to other 3GPP working groups in less than one and a half year - by March 2016.
The primary step taken within a series of Mission Critical Services and functionalities required by the market has been the MCPTT. In Rel-14, which was accomplished in 2017, additional Mission Critical Services were added and improvements to its collection of standardized applications was made, especially in the fields of Mission Critical Data and Mission Critical Video.
Future Railway Mobile Communication System
The present-day 3GPP technology Mission Critical Services is being put to use by the railway community in a very efficient manner just like the public safety. The actual standard for telecommunication services since the late 1990s has become GSM-R. It is an integral part of the European Rail Traffic Management System (ERTMS). Due to the growing demand for higher capacity, more throughput and adjustable deployment options , UIC in association with 3GPP has started working groups and particular activities in order to determine the successor of the GSM-R radio communication system deployed on rails, also known as the Future Railway Mobile Communication System. Future Railway Mobile Communication System (FRMCS) which is designed by the International Union of Railways with the help of various stakeholders from the rail sector is going to be the telecommunication system worldwide in the coming future. Along with being the successor of GSM-R, it will also act as the key enabler for the digitalisation of rail transport. The Global System for Mobile Communications will be succeeded by The Future Railway Mobile Communication System (FRMCS) in the coming future. It will strengthen the industry of railways and will improve the leverage of the potential given by modern communication technology. The goal of The Future Railway Mobile Communication System is to cover mission-critical railway communications with the help of permitting an on-board mobile communication system for railway operators. The important characteristics of the latest 5G-based system are set along the 3GPP architecture. Compared to the present GSM-R system, it has higher reliability, increased performance, covers support for multiple radio technologies, bears agnostic services, has flexible access management, simple as well as smooth migration options and provides application support along with better operational benefits. The objective of FRMCS is to become the global standard, conforming to the European regulation as well as acknowledging the requirements of rail organizations outside of Europe.
