Spark New Zealand Achieves Virtualized VoLTE, IMS and NFV with OpenCloud Solution

By Laura Stotler June 24, 2015

Mobile operator Spark New Zealand has joined the virtualization trend with a VoLTE proof of concept project. The company is using the Rhino Sentinel VoLTE Application Server from OpenCloud to create a fully virtualized VoLTE, IMS and NFV infrastructure.

The project was completed in less than 14 weeks and includes a range of voice and video calling services that work among VoLTE handsets, from VoLTE to SIP soft clients and among legacy communication devices. The proof of concept demonstrates that network convergence and NFV can be achieved fairly easily within VoLTE environments.

The plan is to eventually unify Spark NZ’s mobile and fixed networks on a single IP-based platform using virtualized IMS (vIMS), enabling devices to use the best network available for all services, including broadband, 3G, 4G and Wi-Fi. The VoLTE component will shift 3G voice calls onto 4G networks, enabling more efficient use of mobile spectrum. This will also enable overseas roaming so that customers may directly connect to Spark’s network globally.

For the proof of concept project, Spark NZ worked with Cisco Systems on the network infrastructure, management and packet core functions and Metaswitch on the IMS virtualized capabilities. The OpenCloud solution provided virtualized VoLTE MMTel and SCC functionality.

“We selected OpenCloud on the strength of their VoLTE proposition and their leading position in virtualized VoLTE,” said David Havercroft, COO of Spark. “The speed and flexibility their platform affords us has been critical in the development of Spark’s new virtualized VoLTE solution.”

“OpenCloud’s products are designed to enable agile evolution which has previously been a long-term barrier for telecoms operators,” added David Long, VP engineering, director and co-founder of OpenCloud.

The companies previously collaborated on a similar virtualized VoLTE project on an Amazon EC2 instance provided through Spark. That project featured same-day delivery of OpenCloud’s VOLTE TAS using the Metaswitch vIMS. OpenCloud also worked with several other vendors to fully virtualize VoLTE for Serbia’s VIP Mobile operator earlier this year.
