Public Safety

Use case stories

Public Safety and PPDR users rely on Critical Communications in two main environments:

• Non-urban or natural disaster: there is no, or a lack in, infrastructure to support critical communication;
• Urban environment: during a crisis, raises of connected devices and the use of social Medias for a live snapshot sharing from the event in real-time occurs failure or overloading of infrastructure when it matters.

The Context #1: non-urban or natural disaster

The first context demonstrates loss of connectivity after a natural disaster through 3 stories. The DEDICAT 6G platform deploys coverage on the area where the most count for PPDR users in order to connect them for collaboration and crisis management. This context has defined three stories related to three phases which could be encountered during the crisis management. At the early stage, the DEDICAT 6G platform will reconnect First Responders immediately after a disaster in a non-urban environment by deploying a coverage using AGVs or UAVs (Story #1). The DEDICAT 6G equipment for coverage is defined at the Command-and-Control Center by the operator who has integrated the disaster area coordinates into the system. In order to get early situation awareness from a disaster area, drones or robots are deployed on the scene in order to get video collection sent to the disaster scene. Before arriving, PPDR users are able to get early information on the situation from the scene and prepare first mission to go. Images from the scene are streamed through the DEDICAT 6G platform to users’ smartphones or to operator and field officers Smart Glasses. The DEDICAT 6G platform has already deployed Mission Critical Services for Voice (MC-PTT), Video (MC-Video) and data (MC-Data). The DEDICAT 6G platform supports all communications on the field between users, data collection from users and connected objects (location, video, third data…). First Responders are able to use their smart devices to collect, share and visualize information. The DEDICAT 6G platform is maintained until the response to the crisis ended or operated infrastructure becomes available but can continue to support any failure (this part is described in the second context).

In the meantime, the DEDICAT 6G platform allows PPDR and Public Safety organizations to inform population on the situation (Story #2). Those mechanisms are similar to the UC2 – “Enhanced Experience”. This part describes how the PPDR users are able to share some information with the population which is difficult without DEDICAT 6G capabilities.

First Responders are able to receive collection of data (including video) from the scene before arriving and during the crisis management (Story #3). Based on mechanisms for intelligent distribution and coverage extension, resources of DEDICAT 6G platform can be reallocated depending on missions’ evolution (new area to be covered for data collection or First Responders engagement…). First Responders can leverage information by the use of Smart Sensors, Smart Glasses, new applications on Smartphones or connected to intelligent systems (Weather conditions estimation, databases request based on pictures or voice…). The First Responders will be able to support victims and leverage their mission management experience. This first context will also demonstrate how DEDICAT 6G platform can integrate innovative tools for efficient End-to-End Disaster Response.

The Context #2: non-sufficient working communication services during large event and large crowd

This context describes three stories during a large event with a risk of network failure. The DEDICAT 6G platform will support the available operated infrastructure with mechanisms of dynamic coverage extension to deliver resilient and efficient connectivity for the mission of First Responders. The large event supposed an early organization, involving the DEDICAT 6G preparation and its pre-deployment to event premises. The stories in context #2 start when an incident happened, causing a sudden crowd movement (Story #4). The DEDICAT 6G platform, when has identified the movement, sends a notification to “Site Manager” and “Security” team. Due to the large crowd, the public connectivity comes to its limitation. The Control operator triggers the DEDICAT 6G connectivity support in order to maintain sustainable communication for attendees using the festival mobile application in order to receive evacuation instruction.

DEDICAT 6G platform has deployed a resilient, efficient extended capacity for Security team and First Responders allowing the crisis management (Story #5). With the preparation of the event, First Responders are able to identify position of initial incident in the indoor area of the festival, get feedback from video streaming and take the first decision of response to support victims and starting to secure the area. The mission accomplishment is successfully achieved with DEDICAT 6G. Because of the existence of a public infrastructure and the dynamic coverage extension, DEDICAT 6G allows an interaction between attendees to the event and First Responders (Story #6) in order to involve public in the crisis management value chain by sharing right information for evacuation, be able to collect data to raise situational awareness. DEDICAT 6G is participating to reduce the stress of public impacted by the incident which impact positively the decrease of numbers of victims.
