Public Safety

Overview

Public Protection and Disaster Relief (PPDR) and Public Safety organizations rely on reliable and efficient communications to respond to natural or man-made disasters. In most cases, PPDR and Public Safety organizations own their critical infrastructures which are operated at national level or small cell for tactical or urgent needs.

Those infrastructures have to be available at anytime, anywhere and make all communications efficient for voice or data. With the beginning of 5G deployment, organizations are looking to apply their critical communications on this new technology and balance the choice of solution depending on the long term of investment.

DEDICAT 6G aims to deliver the high level of reliability expected by PPDR and Public Safety organizations by combining the use of operated connectivity (Public or Private) and the high-quality services of a dynamic and split architectures which deserve users on the field.

Public Safety use case aims to demonstrate Dynamic Coverage Extension and Intelligent resource reallocation through two contexts of crisis management.

Public Safety use case overview

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.

Human centric applications

Mission Critical users’ application

The Mission Critical Services (MCS) are integrated to the DEDICAT 6G cloud infrastructure. Based on the orchestrator and agent notification, the platform is able to deploy services where it matters to offer efficient and resilient connectivity.

Based on a cloud server – mobile client architecture, the MCX solution has been split into several components that support the different MCX services independently from others.

This Edge Computing oriented architecture allows the system to automatically redeploy a component in case of a service loss, in order to support critical communications resiliency but also to deploy a specific component to leverage the service efficiency, e.g., MC-PTT in case of an overloaded audio service.

MCX Client application

To benefit from mission critical services provided by the DEDICAT 6G Platform, users need to connect to the services by using a client application. All the critical features shall be delivered through the same application. This application will support the showcasing of access to the platform and performing evaluation. The MCX Client application shall provide Push To Talk (PTT) (voice) group call, video call, video streaming and mapping. To implement the MCX Client, the mission critical services will deliver interfaces allowing the use of main services (voice, video, or data).

Smart Glasses

Optinvent will provide several ORA-2 smart glasses for the scenarios. These devices are Android device platforms, and should each be connected through a local smartphone to a Wi-Fi hotspot to be able to connect to the Internet, since the glasses do not have 4G or 5G intrinsic connectivity. The glasses are standalone devices that allow users to see bright images while maintaining the transparency of outdoor scene. The glasses have embedded GPS so that the position of the user could also be tracked during the event if necessary.

Components for the Smart Glasses to be used in the Public Safety use case

The ORA-2 smart glasses use KitKat Android 4.4 version and are compatible with majority of existing applications from Google Play. One option is to adapt Airbus MCX current API for rescue management that will be implemented in the glasses. Another option is to build a new Android application on the glasses. This point should be assessed in the incoming month to select the best way to build the application.

To interact with the glasses, a touch pad allows the user to go through a specific menu provided by the application that should be developed for this use case. However, to have better ergonomic of application and to let the user enjoy and concentrate on the event, an accessory Joystick with Bluetooth connection with the glasses will be used.

      Coverage extension visualisation dashboard

      In the scope of this use case pilot, a Clearpath Robotics Jackal Unmanned Ground Vehicle/AGV will be used as a MAP to reach a specific location with the aim of providing users with opportunistic wireless network for coverage extension. For demonstration purposes this is accompanied by a coverage extension visualization dashboard  that is connected to the robot and is also integrated with an implementation of coverage extension mechanisms  and with an implementation of the Threat identification and classification mechanism. The coverage extension visualisation dashboard allows the emulation of different user positions and consequently scenarios through the “new scenario” button. The virtual space of the application corresponds to the representation of an area of interest created for the lidar. In the current implementation this corresponds to an area in the parking of WINGS offices. The dashboard allows the configuration of the scenario by dragging and dropping users to different locations. For this scenario it is assumed that the coverage range of Access Points (green), and Mobile Access Points (Yellow) is one square (in each direction). Outside of that range users have connectivity issues that need to be solved. In this demo scenario two types of Mobile Access Points are considered: virtual (dummy) and one that corresponds to the actual Clearpath Robotics Jackal. The dashboard allows viewing robots/AGVs in two-dimensional graphics or in 3D space. A location in the area of interest can be selected to view the coordinates. The Coverage Extension Decision Making algorithm takes into account the scenario input and selects the optimal location for Mobile Access Points and the most appropriate allocation of users/mobile nodes to these Mobile Access Points. In this way all users have now access to the network. The dashboard also enables real space monitoring of the AGV mobile access point navigation to the given coordinates.
