Nokia ready for VoLTE via carrier cloud

Nokia Siemens Network said it has completed testing of mobile voice core services running in a telco cloud network.
 
The company said the service is now “on the brink of commercial deployment.
 
The company successfully demonstrated an exhaustive set of use cases covering voice-over LTE and other IP Multimedia Subsystem (IMS) based services in the telco cloud.
 
NSN last year demonstrated several “proof of concept” projects. These projects provided the technology foundation for core network element software running on top of a virtualized 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.
 
The company said it 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.
