Circuit Switched Fallback (CSFB) is an increasingly important for operators and the good news is that Nokia Siemens Networks can implement it in a mobile broadband network in just four weeks.
Operators need to provide CSFB to be able to utilize ultra-fast LTE data network when launching LTE-capable smartphones like the iPhone 5 and Lumia 920 to the market. CSFB will enable smartphones in LTE networks to change over to 2G/3G for incoming and outgoing voice calls. In many cases, CSFB will co-exist with Voice over Long Term Evolution (VoLTE) well into the future.
Nokia Siemens Networks can provide CSFB to the core network with extremely fast implementation including software and hardware. And don’t just take our word for it. Vodacom South Africa is the first operator inAfricato provide voice and data for LTE subscribers using CSFB based on the Liquid Core, implemented in a record time of four weeks.
Vodacom now has an excellent opportunity to monetize voice and LTE services for new LTE smartphones before its competitors get in on the act. “Higher speed and lower latency translate into a more stable user experience with stutter-free video and almost instantaneous music and picture downloads”, Vodacom says.
As Vodacom can testify, Nokia Siemens Networks is the world’s fastest CS Fallback/LTE company!
CS Fallback is part of Nokia Siemens Networks’ VoLTE solution.
