Trial Sites

ENVELOPE will develop a unified architecture, encompassing a spectrum of infrastructural types. This spans from open-source core implementations like Open5GS/OAI, offering extendibility with new functionalities, to commercial solutions such as HPE core, delivering advanced features and heightened performance.

This diverse framework serves several purposes:

  • 1. Identifying barriers blocking wider adoption of 5GS by vertical services.
  • 2. Assessing the maturity of commercial products.
  • 3. Demonstrating how ENVELOPE APIs’ abstraction layer can streamline development for verticals, irrespective of the underlying infrastructure.

Validation and demonstration will unfold across three trial sites in Italy, the Netherlands, and Greece. Each site will implement the fundamental ENVELOPE architecture but will focus on distinct sets of use cases and scenarios to encompass the broad spectrum of CAM services and their varying characteristics. Every innovative aspect will be integrated into at least one site.


In Italy, the emphasis will be on exploring how advanced 5GS architectures can facilitate dynamic reconfiguration during emergency situations. Here, the network will function as a distributed black box, capable of gathering and reconstructing accident scenes, or even preemptively detecting them to offer crucial guidance for avoidance. The primary deployment scenario will revolve around east/west-bound interfaces, particularly across different edge providers or Mobile Network Operators (MNOs).

Two use cases (UCs):

UC 1: Advanced in-service reporting for automated driving vehicles

UC 2: Dynamic collaborative mapping for automated driving

The Netherlands

Meanwhile, the Dutch site will concentrate on developing and testing new Open APIs to efficiently handle uplink data traffic. This aims to facilitate data collection and the creation of a Digital Twin, operating on servers or at the edge. Leveraging the commercial SA network of KPN, the Dutch site hosts a DT service within a Multi-Access Edge service environment.

Three use cases (UCs):

UC 1: Periodic vehicle data collection for improving digital twin (DT), e.g. for predictive maintenance

UC2: Vehicle testing with mixed reality

UC3: Tele-operated driving aided by DT


Lastly, the Greek site will prioritise vertical control and information delivery to the network/vehicle, along with exploring the interaction between the commercial network of COSM and the private PLMN of the partner NCSRD, particularly in terms of influencing AF (Autonomous Features).

One use case (UC):

UC 1: MEC handover between multiple MNOs
