Nokia Siemens Networks announced today (30 July 2013) that its cloud technology is on the brink of commercial deployment. NSN has been carrying out comprehensive testing of mobile voice core services running in the Telco Cloud.
The company has successfully demonstrated what it described as an “exhaustive set of use cases” covering Voice over LTE (VoLTE) and other IP Multimedia Subsystem (IMS) based services in the Telco Cloud.
During 2012, NSN worked on demonstrating 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.
NSN 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.
Using an industry-standard virtualisation and cloud management infrastructure as well as commercial off-the-shelf IT server hardware, the test program for Telco Cloud deployment verified the automated deployment and elastic scaling of virtualised network elements, live migration of virtual machines from one server to another, and the recovery from hardware failures.
All the cloud test cases were enabled and supported by the existing NSN Operations Support Systems (OSS) portfolio and a cloud application management system which controls the VoLTE core applications in an operator’s private Telco 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.”
NSN has worked closely with major operators and technology partners to define the use cases of the test and verification programme in order to ensure robustness and carrier-grade availability of real-time mobile core applications deployed in a Telco Cloud data centre.
“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 atNSN. “We are strongly committed to bringing our core network solutions to life in the Telco Cloud.”
NSN said it intends to continue to build on its experience and leadership position in Telco Cloud VoLTE projects as well as in Evolved Packet Core (EPC) and register domains, targeting robustness of the 4G core in both traditional and Telco Cloud deployments.
