South Africa's Vodacom has selected Nokia Siemens Networks to enable circuit switched fall back (CSFB) functionality in its LTE network. This functionality allows 4G users to make and receive voice calls using either the GSM or 3G network while retaining the benefit of data services via LTE.

Nokia Siemens Networks has also provided Vodacom with 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.

Once added to the mobile soft switch (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 whole system is monitored, managed and optimized by NetAct, Nokia Siemens Networks' network management system.

In addition, Nokia Siemens Networks 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.
