According to the most recent information, Elisa and Ericsson have launched in-service software upgrade capability on a live 5G SA network.

Elisa is the first service provider in Europe to deploy ISSU on 5G SA network.

Elisa becomes the first service provider in Europe by integrating In-Service Software Upgrade (ISSU) technology on its operational 5G Standalone (SA) network powered by Ericsson. This achievement enables successful changes to the network’s core software without impairing client services.

HIGHLIGHTS

  • Elisa and Ericsson debut ISSU capabilities on Elisa’s operational 5G SA network, a first for Europe.
  • It is possible to upgrade the network’s core software without impairing client services.
  • The Continuous Delivery & Deployment methodology enables the easy deployment of software upgrades.

The dual mode 5G Core technology from Ericsson is now operational on Elisa’s 5G Standalone (SA) network, enabling In-Service Software Upgrade (ISSU) capability, the two companies stated. Elisa has reportedly been the first service provider in Europe to install ISSU on an operational 5G SA network.

Europe’s First ISSU Deployment

Thanks to the ISSU capabilities, Elisa can easily upgrade its core network software without compromising customer services or experiences. This measure is necessary to fulfill Elisa’s cloud-native digital transformation goal since it clears the way for automation and the creation of self-driving networks.

On top of Ericsson’s dual-mode 5G Core solution, which was deployed leveraging containers and Kubernetes orchestration, is Elisa’s cloud-native architecture. This approach has the advantage that each microservice may be upgraded and maintained separately, ensuring continuous service and sustaining network Key Performance Indicators (KPIs) during the upgrade process.

Continuous Delivery and Deployment Model

It is claimed that operators like Elisa may utilize ISSU to introduce new technologies while keeping current service standards, pursuing new commercial opportunities, and reducing the amount of human labor needed for software updates. These capabilities allow Elisa to support more upgrades and deploy new features more rapidly.

deployed on the active production 5G SA network of Elisa Finland.

The ISSU capability is now being implemented with actual customer traffic on Elisa Finland’s live production 5G SA network, and there are plans to expand its deployment to more 5G Core solution components. The deployment’s success was greatly influenced by Ericsson’s Continuous Delivery and Deployment (CDD) pipeline, which automates the procedure and adheres to cloud-native architecture.

Adopting a cloud-native architecture is a crucial step on the road to 5G SA. Beyond technology advancements, it has a significant impact on how a service provider conducts business, enabling more openness, effectiveness, and changeability.

Ericsson and Elisa Partnership

This success, according to a joint statement, enhances the tight cooperation between Ericsson and Elisa. Ericsson was later chosen to provide the 5G Core network for Elisa Estonia’s 5G SA rollout because it would be the first in the Nordic region to establish an end-to-end 5G Standalone connection in 2020. Additionally, in 2019, the companies collaborated to test Ericsson’s private network solution for Elisa’s corporate clients.

With 19 5G SA networks already operational throughout the world and more than 80 cloud-native dual-mode 5G Core clients, Ericsson is still at the forefront of telecom innovation. Through its core networks and Radio Access Network (RAN) business, Ericsson powers 145 active 5G networks, including 24 active 5G SA networks.
