JCI Selects BroadForward to Power Advanced Signaling Solutions for Its Neo-Carrier Strategy

Japan Communications Co., Ltd. (TSE Prime: 9424; hereinafter referred to as "JCI") is pleased to announce that it has selected BroadForward (Headquarters: Netherlands; CEO: Taco Schoute), a global leader in intelligent signaling software. JCI is committed to developing the best core network to power the future of its Neo-Carrier strategy.

As announced on February 14, 2024, JCI is set to launch services as a "Neo-Carrier" on May 24, 2026, to be realized by connecting voice, SMS, and data communication networks to MNOs. Currently, in addition to connecting to emergency call networks, we have begun developing our core system, which connects our network functions (such as HSS*1, IMS*2, and SMSC*3) with the equipment of voice and SMS interconnection operators.
*1 HSS: Home Subscriber Server *2 IMS: IP Multimedia Subsystem *3 SMSC: short message service center

To develop this new telecommunication infrastructure in the best possible way, we believe that we should not rely on a single vendor. Instead, we aim to combine the best solutions for each function. By following this approach, we will develop a new telecommunication infrastructure that offers advanced features and high cost efficiency while keeping the total investment cost to just a fraction of the conventional amount. Based on this policy, we have completed the selection of vendors from six countries, 21 companies. One of these selected companies is BroadForward.

In the telecommunications industry, although global technical standards exist, there are still small technical differences—similar to "dialects" in specifications and compatibility. As a result, high-level adjustments are required to ensure proper connectivity between network components.

BroadForward's solution supports multiple protocols and network functions on a flexible platform, enabling simplified network operations and improved scalability. By implementing BroadForward's Diameter Routing Platform (DRA/DEA), Gateway Mobile Location Center (GMLC), and Signaling Transfer Point (STP), as a "Neo-Carrier," JCI will establish a simpler and more stable communication environment while enhancing its readiness for 5G and next-generation networks.

"JCI is leveraging the world's most advanced technologies from various vendors to develop the best core network as a 'Neo-Carrier.' The introduction of BroadForward's signaling solution will significantly enhance the flexibility and scalability of our network."
