UC #1.2: Digital Mobility

UC #1.2 focuses on real time media service delivery and prioritized communication to the Command and Control Centre (C&CC) in case of emergency situations triggered when detected by AI recognition and identification mechanisms. The required information is transmitted over 5G dedicated slices assuring real time management, E2E orchestration and QoS control.

The entire UC experimentation is taking place inside an AIM bus.

The UC is designed to offer the following vertical’s capabilities:

  • Infotainment/video services in dense, static and mobile environment
    • real time infotainment services will be delivered displaying municipality information and public interest information including: surveys, alerts, tourist information.
    • the captive portal will be connected through the 5G infrastructure to the AIM public traffic management centre for real-time communication.
  • AI recognition and identification of emergency situation. The predefined emergency situations (passenger’s fall, violence, health issue) are triggered by the AI algorithm that identifies and tracks human bodies throughout camera frames and also correlates with other data as head’s coordinates and velocity.
    • in depth assisted pose estimation through different convolutional neural network models, and training data sets for recognition and identification of emergency situation.
  • Prioritized communication to C&CC
    • public safety critical service – identifying public threats (thefts / healthcare emergency / lost items) and allocating on the spot appropriate resources.
    • E2E slice over 5G infrastructure, the emergency situation detected through the AI scheme addressing various emergency scenarios (thefts/healthcare emergency/lost items).

5G-VICTORI France/Romania Facility

This facility involves the French sites (Paris and Sophia Antipolis) and two Romanian sites, one in Bucharest and one in Alba Iulia Municipality (AIM), to instantiate in the two former both 5G RAN and Core functions. The Bucharest site plays the role of IP interconnection point between France and Romania and also connects the AIM site to the cluster for service deployment. The Bucharest site is also the test site for the 5G network elements deployment.

The implemented 5G-VICTORI services need to be integrated in 5G-EVE (highly complex environment) and ready to be deployed within the resulting 5G-VICTORI infrastructure (Paris/Sophia-Antipolis/Bucharest/AIM) to support the UCs.

Developed solution

The UC experimentation design is presented in Figure 1 and involves the creation of two network slices. The blue slice provides internet access in the Bus (Wi-Fi) by using a 5G compatible device connected to the network. The red slice corresponds to a prioritized connectivity slice between the video camera installed inside the vehicle and the computing entity for further Machine Learning (ML)/AI analysis.

Figure 1 UC #1.2 experimentation design for facility requirements

For the network requirements, the specific UC communication characteristics are already evaluated,. Preliminary images are taken from inside the bus to start the algorithms training phases:

  • the blue slice is providing Internet connectivity to the bus passengers for browsing, Downlink capacity 20 Mbps and Uplink capacity 1 Mbps.
  • the prioritized red slice is providing cameras connectivity to the compute area installed in Orange AIM site, Downlink capacity 1 Mbps and Uplink capacity 10 Mbps for good video resolution (1080p).

The UC #1.2 site surveys have been completed and the require locations have been identified. An equipped bus will move around the Orange site facility in AIM to support the mobility UC. The bus journey is near the installed antennas system (described as the ORO site) up to 500 m from the site, covering 2 bus stations. The average bus speed for this scenario is 10 km/h, taking into consideration the traffic conditions in the city, and during experimentation (3 min in average) the bus will remain within the coverage area provided by the 5G gNB.

For video processing and analytics functions a dedicated Edge server is installed at the AIM site, connected to the network. Within this architectural design framework low latency communication can be provided taking less than 1 ms for communication between the core network servers and the edge computing infrastructure.

Service Deployment

The UC is designed to provide:

  • Real-time LV energy metering
    • metering data collection from endpoints deployed at the AIM locations.
    • collected measurements will be transferred to the 5G-VICTORI central cloud facilities to be stored, processed and analysed by the telemetry platform.
    • UC’s will be demonstrated over the 5G-EVE infrastructure providing energy metering services for energy consumers like public buildings and street lighting in AIM.
  • Energy Analytics for predictive and proactive maintenance for AIM LV infrastructure
    • energy analytics application development for real time & historical view as well as reporting of status and parameters.
    • advanced reports focusing on usage, running cycles & times, operational status for AIM LV devices will be developed.
    • QoS graphical visualization and reporting based on LV energy sensor collected data.

alerting events and incidents provoking real time triggers, based on measured parameters and predefined threshold.
