Nokia Siemens Networks said its recent tests of voice over LTE (VoLTE) services in a virtualized cloud environment verify end-to-end readiness of the technology.
NSN's test program implemented end-to-end verification of VoLTE call cases to ensure feature parity with customers' current 2G/3G circuit-switched voice services, Single Radio Voice Call Continuity (SRVCC) functionality, and the reuse of existing billing, lawful interception and intelligent network interfaces.
The tests relied upon an industry-standard virtualization and cloud management infrastructure as well as commercial off-the-shelf IT server hardware, said NSN. It added that the test cases were enabled and supported by NSN's OSS portfolio and a cloud application management system that controls VoLTE core applications in an operator's private cloud.
"The range of test cases we ran during the pre-deployment verification phase underlines the essential role of the OSS components in the Telco Cloud," said Peter Patomella, vice president, operations support systems at NSN.
"We've shown how the complete lifecycle of a network element can be managed remotely via our OSS--including initial network element cloud deployment, monitoring of virtualized VoLTE application resources, and elasticity management," he added.
