Ericsson and Telcaria unlock new approaches for 5G Energy Efficiency optimization

Ericsson collaborates with Telcaria, a Spanish SME specialized in the research and development of new telecommunication solutions and official collaborator of 5TONIC, for identifying innovative solutions for enhancing energy efficiency of end-to-end vertical applications relying on 5G Advanced technologies.

The collaboration has been forged in the context of 6G-DAWN project coordinated by CTTC, a research and innovation project running since 2022 until end of 2024, being funded by the Recovery, Transformation, and Resilience Plan of the Spanish Government via the UNICO 6G I+D programme.

Ericsson and Telcaria are jointly researching novel mechanisms for evaluating, recommending, and enforcing alternative configurations of that may enhance energy efficiency indicators for Private 5G Advanced Networks. The intent of this initiative is, on the one hand, securing the minimum energy consumption levels of 5G Private Networks without impacting other network performance parameters, and, on the other hand, assessing and optimizing network energy consumption for delivering traffic at speeds up to 1 Gbps over 5G mid-range bands.

The strategy followed entails adopting a PNI-NPN (Public-Network Integrated Non-Public Networks) approach for offloading and reducing the energy consumption of the Control Plane, and improving the predictability of both network performance and end-user service patterns in the actual field for further reducing the energy consumption of the RAN.

The exposure of energy-consumption information can help CSPs and Enterprises in understanding where and when energy is consumed, and which factors are influencing this consumption. This, together with the inclusion of enhanced mechanisms to optimize the network configuration, both statically and dynamically, can help companies operating and leveraging private cellular networks in manufacturing, logistics and transportation industries, among others, to reduce their operational expenses and their carbon footprint.

For enabling the experimentation and validation activities in this context advanced technologies like Network Digital Twin and Network Exposure have been integrated at 5TONIC lab, and a Private 5G Advanced Network system has been deployed at the EXTREME Testbed of CTTC.

Maria Felisa Sedano, CEO at Telcaria, adds: "This collaboration represents a great opportunity for us to explore new challenges in energy efficiency within the future of cellular networks, ultimately unlocking new possibilities and strengthening our cooperation with Ericsson."

“Ericsson and Telcaria are opening new avenues for enhancing 5G network energy efficiency, enabled by the application of instrumental technologies such as PNI-NPN, Network Digital Twin and Exposure for Private Network capabilities.” - indicates Manuel Lorenzo, Head of Technology & Innovation at Ericsson Spain.

Decentralized AI-native 6G network management for resilience and sustainability

Press Release

The expected growth and scale of 6G networks shall demand crafting new and smarter network management paradigms. Multiple stakeholders will jointly define the ecosystem, and this poses several administrative and technical challenges. Natively embedding AI-based cycles while delegating decisions throughout the network offers the required resilience and sustainability at scale. A consortium of four industrial partners (ERICSSON Spain, EVIDEN, Software Radio Systems and Telcaria) representing the 5G and beyond value chain and led by the CTTC (Centre Tecnològic de Telecomunicacions de Catalunya) are investigating these challenges within the framework of the UNICO R+D project 6G DAWN.

6G DAWN is a 2.6M€ research and innovation project funded by the Recovery, Transformation, and Resilience Plan of the Spanish Government via the UNICO I+D programme, which fosters the creation of a Spanish industry-academia 6G ecosystem.

6G DAWN proposes a zero-touch distributed 6G network management plane to handle the deployment of a massive number of network slices (virtual networks built over the same shared physical infrastructure) covering all network segments (i.e., RAN, Transport, Core, Cloud, Extreme Edge). The main challenges are elasticity (the capacity to adapt to varying demands and network conditions to improve the energy efficiency and sustainability of the network) and resilience (guaranteeing secure and continuous operation among the multiple stakeholders). Furthermore, given the increasing scale, automated energy-aware decision-making appears as a transversal component of any sustainable 6G network. In this respect, AI is natively embedded in the architecture at the various decision levels by enabling the support of techniques such as federated learning, graph neural networks, and explainable AI, which are coordinated towards a global network-wide goal. Provided these essential characteristics, 6G networks will be well-equipped to address a wide range of vertical requirements, enabling them to become the foundational infrastructure for diverse industries, including automotive, industry 4.0, extended reality (XR), energy, eHealth, and emergency response systems, hence will become the backbone of society.

Multiple proof-of-concepts (PoCs) are being built to experimentally validate the potential of such an AI-native decentralized management architecture in a variety of close-to-real scenarios. This includes dynamically adjusting radio access network (RAN) parameters in open RANs, energy optimization of non-public networks (NPN), the integration of the extreme edge in the network management framework, intrusion detection and mitigation, and QoS and network resiliency optimization. The PoCs are deployed having the EXTREME Testbed® of the CTTC as a central experiment-as-a-service facility, with some of the components distributed in labs of the industrial partners.

Ericsson and CTTC join forces to tackle massive network slicing challenges in advanced 5G and 6G networks

Press Release

This collaboration is part of the UNICO I+D program, supported by the Spanish Ministry of Economy and Digital Transformation and NextGeneration EU, with the goal of establishing a sustainable Spanish 5G/6G innovation ecosystem through collaborative research.

The collaboration centers on two significant research projects, 6G-DAWN and 6G-BLUR, which address technological challenges in implementing and scaling what it terms "massive" network slicing - network slicing at a scale that matches the size and scope of what the industry envisions for 6G. The research will develop design principles and technical implementations, including Proofs of Concept (PoCs), to be shared with Spanish and European 5G/6G research communities.

The primary objective of these projects is to empower communication service providers (CSPs) to seamlessly enhance their network slicing capabilities, transitioning from early-stage deployments to future scenarios. This focus is particularly relevant for non-public networks (NPNs) interconnected with public networks.

In simple terms, the research revolves around four key technological areas:

  • Resource flexibility: Optimizing network performance by distributing resources flexibly, especially for massive network slicing. This includes efficient distribution of 5G network functions and leveraging edge computing.
  • Energy efficiency and sustainability: Reducing energy consumption across the entire network, from core to edge, RAN and user equipment, with a focus on sustainability.
  • Zero-touch automation: Speeding up the launch of new NPN services through automatic adaptation and self-configuration within the public network and edge environment.
  • Network resiliency: Ensuring network integrity and reliability using advanced machine learning algorithms to detect and prevent potential service disruptions.

Manuel Lorenzo, Head of Technology and Innovation, Ericsson Spain, says: “5G is rapidly becoming a ubiquitous technology with the potential to connect every person, business, and machine worldwide. Looking ahead, the expected demand for the expansion and enhancement of advanced 5G deployments demands new research and innovation across all aspects of the architectural evolution from 5G to 6G. That's why Ericsson and CTTC are collaborating in the 6G-BLUR and 6G-DAWN projects, sponsored by the Spanish Ministry of Economy and Digital Transformation.”

Josep Mangues-Bafalluy, Head of the Services as networkS (SaS) research unit, CTTC, and co-Principal Investigator, 6G-BLUR and 6G-DAWN projects, says: The 6G-DAWN and 6G-BLUR projects focus on network slicing, NPN integration, energy efficiency, and zero-touch network automation, utilizing various artificial intelligence techniques, and sow the seeds for the creation of an advanced 5G and 6G industry-academia ecosystem. This ecosystem will be cultivated through research collaborations, such as the one between Ericsson and CTTC. This new collaboration will further strengthen our relationship in areas with high potential to transform the way mobile networks are managed at scale. The outcomes of these projects will have a lasting impact on the research and industrial communities of 5G and 6G."
