Vodacom with over 45 million customers selects Nokia Siemens’ Liquid Core for LTE/4G network

Telecom Lead Africa: Vodacom, African mobile communications provider with over 45 million customers, has selected Nokia Siemens’ Liquid Core to enable circuit switched fall-back (CSFB) functionality in its LTE/4G network.

Nokia Siemens Networks said this functionality allows 4G users to make and receive voice calls using either the GSM or 3G network while retaining the benefit of ultra-fast data services via LTE.

Nokia Siemens has also provided its single radio access network (RAN) based on its Flexi Multiradio Base Station. The company will also deliver planning, implementation, optimization and support services for the network.

“We wanted to ensure that our customers get a unified service by being able to access both mobile voice and SMS services alongside 4G/LTE data services,” said Andries Steenkamp, managing executive, core network engineering at Vodacom South Africa. “Nokia Siemens Networks has surely given us a head-start over competition by providing a solution that meets our requirements. The fact that it was deployed in record time gave us an edge over others in the market.”

Vodacom South Africa will benefit from Nokia Siemens’ Liquid Core architecture, based on its mobile soft switch (MSS) with CSFB. Once added to the MSS, the CFSB functionality allows the operator to reuse existing GSM and 3G investments to provide a unified voice and SMS service for people using its 4G service.

The Finland headquartered Nokia Siemens has also provided services for access network planning and data fill for overlay MSS. This includes spare part management, emergency support, troubleshooting and training services.

Paul Divall, head of the Vodacom South Africa customer team at Nokia Siemens Networks, said: “The CSFB functionality was integrated into the operator’s live network with optimized call set-up times and bought it into commercial operation within a time span of four weeks. This achievement further strengthens our business relationship and paves the way for greater opportunities in the future”.

Nokia Siemens claims that it delivered CSFB to 30 customers across the globe.
