SOFTWARE SOLUTIONS FOR EFFICIENTLY MANAGING DIAMETER SIGNALING GROWTH
Mobile operators continue to add LTE and IMS network infrastructure to support growing customer demand for VoLTE and VoWIFI services, while also replacing/removing legacy infrastructure to improve operational efficiency and lower TCO. All EPC and IMS core networks make extensive use of the Diameter signaling protocol for authentication, centralized subscriber data management, location services, advanced policy control, and converged charging functions. Furthermore, connectivity between the existing SS7- based 2G/3G packet core systems and the Diameter-based EPC and IMS networks will continue to be an important requirement for the foreseeable future. This evolution to the all IP network results in a large number of Diameter interfaces to appear on the network, resulting in a larger number of physical switch ports, configuration, and troubleshooting complexity. The NetNumber Diameter Signaling Controller (DSC) permits operators to easily manage the rapid growth of the Diameter signaling network with lower complexity, lower cost, and simpler administration. The NetNumber TITAN platform enables the ability to combine the DSC with other virtual network functions under a common virtual machine or bare metal COTS compute platform with high resiliency and single point of administration (GUI or API) across all nodes.
