OpenSlice 2025Q2 Release

July 22, 2025

Release Date: 18 July 2025

We’re excited to unveil the Release 2025Q2 of OpenSlice, proudly developed and delivered by the ETSI Software Development Group for OpenSlice (SDG OSL).

OpenSlice continues to push the envelope in integrating cutting-edge technologies, striving to meet the dynamic challenges faced by modern telecom environments.

In this release, we place a strong emphasis on enhancing user experience and strengthening system observability, bringing both visual and architectural improvements. The frontend has been updated to a newer Angular version, accompanied by a redesigned landing page that streamlines navigation and improves first-time user experience (FTUE). To deepen insights into service behavior and platform performance, a comprehensive set of metrics endpoints has been introduced, covering general TMF-related information, Service Orders, Services, and Resources, as well as NFV-related metrics. These metrics are now directly consumed by the UI, making operational data more accessible and actionable for users.

We have also expanded the testbed capabilities exposed via OpenSlice by enabling the integration with 3GPP CAPIF Core Function instances. This integration abstracts away underlying complexity and enables secure, streamlined exposure of Service API invocations. It lays the groundwork for empowering current orchestration flows with automated CAPIF Invoker registration, token acquisition, and subsequent calls to discovered Service APIs. In parallel, API compatibility has been improved by updating TMF interfaces - such as the TMF633-based clone endpoint for GST ServiceSpecifications, which creates a Service Specification template based on GSMA’s Generic Slice Template (GST) - to their latest version, ensuring OpenSlice remains aligned with evolving industry standards.

At the same time, OpenSlice confidently steps into the AI era, introducing seamless, AI-driven management capabilities through its integrated Model Context Protocol (MCP) Server. Designed to support intuitive, chat-based user interactions via an MCP client of choice, this experimental feature brings a conversational layer to telco operations - aligning with the broader industry shift toward intelligent service management and automation. With this, we aim to lower the learning curve, simplify access to complex functionalities, and pave the way for more autonomous, user-centric telco operations.

We invite you to discover the new features and enhancements, and as always, we welcome your feedback as we continue to innovate together.

What’s New in OpenSlice 2025Q2

Landing Page Redesign & Metrics View

To enhance First-Time User Experience (FTUE), the landing page has been redesigned for a cleaner, more intuitive experience. A new Metrics view now provides critical insights about the overall utilization across the deployment.

OpenSlice Addons Expanded

The Addons repository is growing! Notable new addition:

  • CAPIF Invoker: A new controller that serves as a 3GPP CAPIF API Invoker Management layer. It authorizes access to CAPIF services, manages invokers and token distribution, and facilitates the triggering of exposed Service APIs.

Model Context Protocol (MCP) Server

OpenSlice now includes an experimental built-in MCP Server, enabling AI-powered interactions. Users can connect using their preferred MCP Clients to:

  • Browse product/service catalogs
  • Order services
  • Preview service orders
  • Interact with deployed service/resource instances - all through a conversational AI interface

CI/CD Pipeline Enhancements

We’ve introduced a new pipeline that builds and publishes each OpenSlice artifact while respecting internal dependencies. This minimizes manual intervention and improves build reliability across the board.

METRICO Evolution

METRICO now offers greater stability and supports day-2 reconfiguration. Users can dynamically adjust metrics intervals, sources, and duration - improving observability and control post-deployment.
