Net-AI-APPs

Enabling the Delivery of Cognitive Services in B5G Networks

A research project that reimagines the mobile core as both a consumer and a provider of Artificial Intelligence. Net-AI-APPs evolves the 3GPP Network Data Analytics Function (NWDAF) and the User Plane Function (UPF) into an open, microservice-based platform where network functions, operators, and third-party B5G applications can request, train, and consume AI services — turning raw network metrics into actionable, cognitive, and sustainable services.

Overview

What the project is about

From B2B-driven 5G to a natively cognitive Beyond-5G core.

5G was designed with a strong B2B focus, delivering gains in latency, data rate, and reliability across industry verticals. To meet the specific needs of each vertical, ETSI introduced the concept of the NetApp — a virtual, 5G-enabled application that can operate autonomously and cooperate with other NetApps to compose more complex vertical services. In the 5G Core, the NWDAF is the function responsible for processing network data and producing insights, but it is traditionally managed exclusively by the operator, limiting external developers and integrators.

Net-AI-APPs proposes an enhanced, microservice-based architecture for the NWDAF that lets external entities — the NetApps — consume existing analytics or create new ones, adding new analytic and model-training functions on demand. This introduces the notion of Network Metrics as a Service (NMaaS), exposing AI metrics of the mobile network in a distributed and accessible way, and creating the conditions for a new class of AI-native applications: the Net-AI-APPs.

Objectives

Specific objectives

  1. Leverage NWDAF analytics capabilities to establish a more flexible architecture able to incorporate new analytic functions, machine-learning models, and agents that consume network-produced data for control and operation.
  2. Evolve the NetApp concept toward Net-AI-APPs, so applications can interact with the mobile core APIs and simultaneously consume or offer AI capabilities.
  3. Develop and validate mechanisms integrating analytics, network functions, and applications over a free5GC-based infrastructure.
  4. Investigate use cases of distributed AI and mechanisms that transform raw network metrics into useful, service-level information.
  5. Carry out integration and experimentation in test environments, assessing the functionality of the proposed solutions.
  6. Disseminate results through papers, software, technical material, and participation in scientific events.
