Mavenir Systems chosen by Hi3G Access for 4G to 3G fallback

Mavenir Systems has been selected by mobile operator Hi3G Access (Hi3G) Sweden for the deployment of its Circuit Switch Fallback (CSFB) solution. 

Circuit Switch Fallback (CSFB) enables circuit-switched voice and SMS services to be delivered to LTE handsets so they ‘fall back’ to the 3G network to complete voice calls. With CSFB, Hi3G can support the new LTE-enabled smartphones for voice and SMS.

Mavenir's VoLTE IWF (InterWorking Function) has demonstrated very rapid implementation into any network, thereby providing Hi3G with an extremely fast time to market, enabling Hi3G to get the system up and the network ready quickly with minimal impact on the current network as no network upgrades are required.

‘CSFB is essential to the introduction of LTE smartphones before VoLTE is introduced. We selected Mavenir because of their proven CSFB technology, their speed to market and the ease of integrating into our LTE network,’ said Magnus Berg, project owner at Hi3G.

Both functions supported by Mavenir’s VoLTE IWF, CSFB and SRVCC, share the same hardware and software platform, Mavenir's carrier grade, ATCA-based, mOne Convergence Platform.

Mavenir delivers converged voice, video and messaging solutions based on its mOne Convergence Platform, to wireless operators globally. The company’s IMS and cloud-based solutions enable legacy core networks to be used for new services such as VoLTE and RCS (rich communication services), and by providing uniquely innovative solutions to address the challenge of migrating subscribers and services to 4G.

Hi3G ACCESS AB (Hi3G) is a joint venture between Hutchison Whampoa (60%) and investor AB (40%). Hi3G Access AB owns and operates commercial 3G networks in Sweden and Denmark.
