BT, one of the world’s leading providers of communications services and solutions, 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. BT provides Evolved Packet Core (EPC) functionalities to other Mobile Network Operators (MNOs) for 4G LTE international roaming.
According to Genband, the Diameter Edge Agent (DEA) function within their solution enables rich interworking between multi-vendor LTE networks to ensure that roaming subscribers can easily connect when on the road with service transparency and resiliency. The solution 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.software, added Genband.
The integrated QUANTiX DSC that can be delivered on a common hardware platform and via centralized management, delivers a Diameter Routing Agent (DRA), a Diameter Edge Agent (DEA), a Diameter gateway interworking function (IWF), and a Diameter load balancer.
“Our strong relationship with GENBAND has helped to accelerate the growth of our wholesale network, supporting rapid expansion of our global footprint and enhancements to our GIPX services that meet customer demand for international roaming and increasingly data hungry applications,” said Steve Sherry, Head of (G)IPX Signalling, Messaging and Numbering for BT Wholesale. “The DSC solves complex Diameter signaling interworking, enabling network roaming across otherwise incompatible mobile networks. It 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. GENBAND’s professional services organization has supported our ambitious plans in the marketplace – building and operating these critical solutions that drive revenue generation and customer satisfaction.”
"Although there are over 260 LTE networks in service worldwide, there are few interconnect roaming agreements in place between different mobile networks and this deployment marks a significant milestone for international mobile network operators,” said David Hiscock, Senior Vice President of Sales for Europe, the Middle East and Africa for GENBAND. “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 enhanced BT GIPX solution addresses these challenges for BT’s international wholesale network, providing a seamless experience for roaming subscribers across 170-plus countries and varying vender equipment and host network scenarios.”
