BT GROUP ADVANCES ENTERPRISE SERVICE INNOVATION BY ENABLING FUTURE-PROVEN BUSINESS SERVICES WITH OPTIVA PLATFORM

BT Group, the United Kingdom's leading mobile and fixed telecommunications provider, has broadened and strengthened its partnership with Optiva Inc. to implement innovative business-to-business and business-to-business-to-everything BT network communications services using Optiva's latest state-of-the-art application server. Central to this initiative is the Optiva charging engine, a cloud-native, open-architecture service creation platform featuring Optiva's Open API framework. The advancement will enhance BT Group's ability to expand cutting-edge services and create new revenue opportunities.

In January, 2024, Optiva announced BT Group's selection of Optiva for its next-generation application server upgrade. The platform upgrade allowed BT Group to evolve from legacy technology, modernize services and increase 5G network coverage penetration with a fully flexible service creation environment. The new platform's rapid design, testing, deployment and integration capabilities support BT Group's partnerships across various industries.

Optiva implemented new interfaces and technologies to transform the traditional network into a next-generation network. Enterprise applications are essential for BT Group's B2B services and cutting-edge consumer applications, which must be modernized in parallel with the network's evolution. Furthering their joint vision, Optiva and BT Group will advance the platform to the next level by integrating B2B services to enhance and deliver their network convergence capabilities with unmatched flexibility.

The network evolution enabling the modernization of B2B applications is supported by:

• A convergent network communication suite to handle any type of core network;
• Enrichment enabled by modern APIs;
• Enablement for autonomous deployment and operations to provide an unmatched B2B experience.

"Our partnership with Optiva empowers BT Group to rapidly evolve our services offerings for customers with confidence. Our collaboration enables us to deploy platforms that will drive future growth and advancement of technological capabilities and innovative solutions," said Nitin Patel, director of mobile and messaging at BT Group.

"Today's announcement represents a milestone in our partnership with BT Group. We are dedicated to our joint vision of building upon our innovative technology to expand B2B and B2B2X services, delivering next-generation application services to drive BT Group's growth," said Robert Stabile, chief executive officer at Optiva.
