FRMa Railway Mobile Communication System) is the railway industry’s next-generation communication system, intended to replace GSM-R with broadband, secure and interoperable services.
The Plugtests series is ETSI’s way to ensure that different vendors’ implementations actually work together in practice — not just on paper.
The 5th edition brought together a large multi-vendor lab with more than 170 participants, simulating an environment close to real railway deployments.
This allowed us to integrate and test against multiple 5G cores from different vendors in a shared interoperability lab.
This is important because in live railway networks, MCX services must operate reliably across whichever 5G core an operator chooses. Demonstrating multi-vendor compatibility is therefore a key milestone for market readiness.
In simple terms
We verified that a user can start a spontaneous push-to-talk group — for example, “all staff in this station right now” — and later end it cleanly. The group is created dynamically by the MCX system and correctly transported through the 5G core.
MCPTT is not like a normal voice call — only one person (or a controlled set of people) speaks at a time. The mechanism that manages this is Floor Control (FC).
Basic FC
– Effect of priorities
[FC/BASIC/02]
Advanced FC
– Revoking the floor when a timer expires (T2)
[FC/ADV/01]
– Queueing requests after release
[FC/ADV/02]
– Queueing requests after revoke
[FC/ADV/03]
Awareness and special cases
– Functional Alias (FA) display during FC
[FC/FA/BASIC/01]
FA allows users to speak under a role (e.g., “Train Driver 17”) instead of a personal name.
– Multi-talker basic operation
[FC/MT/BASIC/01]
– Location sharing during FC
[FC/LOC/BASIC/01]
– Location sharing during multi-talker FC
[FC/MT/LOC/BASIC/01]
In simple terms
We validated that:
– the system correctly assigns the “right to speak”
– priority users override lower-priority requests
– the floor is revoked automatically if held too long
– queued talkers get their turn in order
– operators can immediately see who is speaking (via alias/role) and, when relevant, where they are — even in multi-talker situations
These are essential railway features, enabling dispatchers and field teams to maintain clear, disciplined voice communication in high-stress situations.
Mission-critical voice requires guaranteed quality (latency, priority, stability). In 5G, this is achieved via dedicated QoS flows.
We tested:
– Creating a unicast 5GS QoS flow via Rx
[PCC/5GSQOSFLOWSETUP/Rx/02]
– Creating a unicast 5GS QoS flow via N5
[PCC/5GSQOSFLOWSETUP/N5/02]
– Updating a unicast 5GS QoS flow via Rx
[PCC/5GSQOSFLOWUPDATE/Rx/02]
In simple terms
We checked that the TASSTA MCX server can request mission-critical treatment from the 5G core — using standard 3GPP policy control interfaces — for specific users’ media streams.
This allows the network to prioritize MCPTT traffic over normal data traffic, which is a core requirement for FRMCS deployment.
This Plugtests edition showed the ecosystem moving from “specification compliance” to field-ready interoperability.

At the heart of this transformation was a mobile safety command center built by Swisscom Broadcast, powered by TASSTA’s Push-to-Talk over Mobile (PTToM) technology. This was not just an upgrade—it was a world first for cycling safety, bringing together voice, video, GPS tracking, and real-time data into a single, fully connected system.
Key features of the deployment included:
“Swisscom Broadcast earned my trust last year with their flawless communication solution. They understood our needs for a safety command center and delivered perfectly.”

Telekom has partnered with TASSTA and Motorola Solutions to deliver this solution. Motorola provides the resilient infrastructure backbone, while TASSTA contributes its 3GPP-compliant MCX platform, already validated in real-world tests with German public safety organizations. Together, they create a communication environment that is both future-ready and field-proven.
T Mission delivers tangible benefits for emergency services:
As Gottfried Ludewig, Head of Public at Deutsche Telekom, explains:
“With T Mission, we put a blue light on critical data. Voice, video, and information from first responders take priority in our network — ensuring faster coordination, clearer communication, and greater safety for teams in the field.”
Telekom plans to expand T Mission with Interworking Function (IWF) by 2026, creating a seamless bridge between MCX and TETRA. This step will enable organizations to adopt next-generation services like MCPTT, MCVIDEO, and MCDATA while maintaining trusted legacy systems during the transition.

]]>Mission Critical Push-to-Talk (MCPTT) is a global standard defined by 3GPP for secure, instant, and reliable voice communication over LTE and 5G networks. It is designed specifically for industries where communication is vital—such as public safety, emergency services, defense, transportation, utilities, and enterprise operations.
MCPTT aims to provide the same level of reliability and functionality as traditional public safety Land Mobile Radio (LMR) systems while leveraging the broader coverage and capabilities of commercial mobile networks. It enables users to communicate at the push of a button, similar to a walkie-talkie, but over cellular infrastructure like 4G and 5G.

Guaranteed Communication Under Any Circumstance
MCPTT ensures prioritized access to communication networks during emergencies, natural disasters, or network congestion—when traditional systems often fail.
Interoperability and Standardization
Built on 3GPP standards, MCPTT allows for seamless coordination across different agencies, technologies, and sectors.
Enhanced Situational Awareness
In addition to voice communication, MCPTT systems often support tools for location tracking, status updates, and incident coordination—empowering faster and more informed decision-making.
Group Communication
Supports both individual and group calls, streamlining collaboration within teams during time-critical operations.
Security
Leverages the advanced security architecture of LTE networks, including encryption and authentication mechanisms.
Prioritization and Pre-emption
Ensures that high-priority users and messages can bypass lower-priority traffic when necessary, guaranteeing that critical communication is never delayed.

T.Flex
