During 2012, Nokia Siemens Networks demonstrated the reliability of core virtualisation in several “proof of concept” projects. These projects provided the technology foundation for core network element software running on top of a virtualised infrastructure. In addition, the projects helped identify telco-specific requirements for cloud computing.
Nokia Siemens Networks has now carried out further testing to verify end-to-end VoLTE deployment readiness in a Telco Cloud. The test program tackled current deployment barriers by implementing comprehensive 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 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 Nokia Siemens Networks. “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.”
Nokia Siemens Networks has worked closely with major operators and technology partners to define the use cases of the test and verification program in order to ensure robustness and carrier-grade availability of real-time mobile core applications deployed in a Telco Cloud data center.
“Nokia Siemens Networks has achieved an important milestone in making the Telco Cloud a commercial reality for mobile broadband operators,” said Michael Clever, vice president, Voice and IP Transformation at Nokia Siemens Networks. “We are strongly committed to bringing our core network solutions to life in the Telco Cloud.”
