Airbus Public Safety and Security and Capgemini Demonstrate MCX Solution at ACMOSS

As part of the preparation for the opening of service of the Radio Network of the Future (RRF) in April 2025, ACMOSS began demonstration sequences of the first deliveries of the RRF's critical communications services on June 6, 2024.

A first demonstration carried out in the ACMOSS premises on June 6, 2024 by the Airbus and Capgemini teams, made it possible to test and observe the stability of the technical base and the first block of functionalities which makes up the first test milestone of the target technical architecture of the RRF. The first milestone demonstrated includes:

1. Access to the Orange radio network interfaced with the RRF core network, with an “RRF operator” SIM card;
2. The technical base supporting the RRF services when the service opens: infrastructure, MCX platform (critical mission communications) and core network;
3. The first block of functionalities of the RRF's critical communications services (mobile telephony, MCX services, dispatcher console, interoperability with low-speed networks)

The results of this demonstration were satisfactory and allow ACMOSS to organize three test sessions in field conditions between June 26 and July 3 in the Loire (42), Bouches-du-Rhône (13), and Val-de-Marne (94) region.

These fieldtests will allow future users to verify the proper functioning of the RRF's critical communications services, to observe their stability and to test their functionalities as part of their operational activities dedicated to personal rescue missions.

The stability during this first integration demonstrated  that the RRF's critical communications services  makes it possible to materialize the ambitions of ACMOSS and the needs of future users for the RRF in terms of resilience, sovereignty and interoperability between security and rescue continuum services:

• The architecture of the MCX server is stabilized, and integration into the ministry’s data centers continues;
• The RRF SIM card operates from the Orange network interfaced with the RRF core network, and will provide independence in the face of load hazards on the operators' radio access network thanks to a pre-emption priority mechanism out of two operators;
• MCX services enable efficient and fluid “field/operational room” communications, with the aim of exchanging multimedia content;
• The direct mode in its initial version in June works nominally (it will be enriched by December with a relay mode) and makes it possible to maintain communications in situations of network degradation;
• The RRF operates via a 4G key connection, thanks to rapid installation of the dispatcher station and the radio gateway allowing communications in interoperability with low-speed networks.

This first delivery milestone will be followed by three others by the fall, thus making it possible to materialize the progressive construction of the RRF until the opening of service at the beginning of 2025.
