BT taps Genband QUANTiX Diameter Signaling Controller to expand IP Exchange solution

BT has selected the Genband QUANTiX Diameter Signaling Controller (DSC) to expand its existing Global IP Exchange (GIPX) solution with LTE signaling and data roaming exchange capabilities for its mobile network operator (MNO) customers.

The GENBAND QUANTiX DSC enables interworking between LTE networks to ensure that roaming subscribers can easily connect when on the road with service transparency and resiliency.

Steve Sherry, head of (G)IPX Signalling, Messaging and Numbering for BT Wholesale, said: “The DSC solves complex Diameter signaling interworking, enabling network roaming across otherwise incompatible mobile networks.”

DSC also provides the security and routing scalability required to handle the explosion of mobile data traffic exchange for enhanced services, such as RCS, photo sharing, video and Over-the-Top (OTT) applications.

BT is providing Evolved Packet Cores to mobile and other network operators to deliver international subscriber roaming capabilities onto their customers’ networks.

The selection of the QUANTiX DSC provides BT with a Diameter Edge Agent (DEA) function, which supports interworking between vendor equipment that is being deployed across its customers’ LTE networks.

In addition, the software provides context-aware intelligent routing, scalable handling of SIP and Diameter traffic, and secure, seamless connectivity to any IMS/LTE network resulting in a simple, cost-effective deployment of rich LTE voice and data services.

In the past, mobile service providers had to negotiate bi-lateral roaming agreements with network operators, implement point-to-point Diameter interconnects, and handle interoperability challenges between LTE and legacy 2.5G/3G networks. The BT GIPX solution addresses these challenges for BT’s international wholesale network.
