Shanghai, China, June 29, 2013]: Huawei, a leading information and communications technology (ICT) solutions provider, today announced a successful end-to-end test of its Ultra-Flash CSFB (Circuit Switched Fallback) voice solution to dramatically improve call setup times from LTE to GSM or UMTS.
After a smartphone on LTE places a voice call, Ultra-Flash CSFB allows the network to simultaneously send an indication to the smartphone to fallback from LTE to GSM or UMTS and to the circuit-switched core network to prepare resources for the smartphone. Standard CSFB solutions require first sending an indication to the smartphone and then accessing the GSM/UMTS network.
The end-to-end test was completed at Huawei’s Shanghai mLAB research center, and was conducted on a real radio access network, packet core network, circuit-switched core network and commercial smartphone. The test results showed 20% faster call setup times compared to legacy GSM or UMTS network calls.
The successful test marks a milestone for LTE voice technology innovation and evolution, and will help meet a growing need for dedicated end-to-end voice solutions for LTE networks beyond what is currently offered.
Ultra-Flash CSFB is a part of Huawei’s SoftMobile suite of solutions that builds upon the successful foundation of SingleEPC, SingleRAN and SingleCore solutions amid industry movement away from voice-and-text, pure-pipe services to an era of data diversity and new vertical market revenue streams. SoftMobile provides ocean-like broadband, orchestration and on-demand network features to leverage the creation of new mobile broadband business models.
SingleEPC has been deployed for more than 240 mobile operators in over 128 countries.
