According to Boost, the deployment will enable faster delivery of advanced services, enhanced network automation, and more efficient cloud utilisation than its Open RAN cloud-native network could before.

Nokia says the deployment includes the consolidation of several IMS voice 3GPP functionalities into a single cloud-native network function (CNF), called Nokia Cloud Native Communication Suite (CNCS).

The migration, from Boost Mobile’s previous distributed IMS voice core by Nokia, is claimed to provide automated deployment and configuration, reduced infrastructure footprint, and lower operational costs through streamlined life cycle management.

“We anticipate Nokia’s 5G Voice Core to help reduce our network infrastructure costs by about 70% in addition to delivering new 5G services faster, with significantly streamlined network operations,” said Dawood Shahdad, Vice President of Core Engineering at Boost Mobile.

“Boost Mobile continues to push boundaries with our Open RAN 5G network and the successful nationwide deployment of Nokia’s cloud-native next-generation voice core marks a pivotal moment in our network evolution, as this new network element advances our vision of end-to-end orchestration and dynamic scaling on our path toward 6G.”

CNCS improves energy efficiency by about 10% to 20%, relative to a standard IMS Voice Core, according to Nokia data.

“As the sole 5G Voice Core provider for Boost Mobile in the US, Nokia is extremely pleased to support Boost in this modernisation project and the close partnering that enabled it," said Marcelo Madruga, Head of Technology and Platforms, Products & Engineering, Cloud and Network Services at Nokia.

"This is another demonstration of Nokia’s technology leadership in helping our customers solve problems, address their customer needs, and generate new revenue streams.”
