A milestone for LTE voice technology innovation and evolution: Huawei goes forward.

As a information and communications technology (ICT) solutions provider, we can observe that Huawei is highly involved in Research and Development, to increasingly improve and innovate
its portfolio of products and services. In this dynamic, today Huawei, the Chinese provider, has announced a successful end-to-end test of its Ultra-Flash CSFB (Circuit Switched Fallback) voice solution with the goal to help meet a growing need for dedicated end-to-end voice solutions for LTE networks beyond what is currently offered.

According to Huawei, The test results showed 20% faster call setup times compared to legacy GSM or UMTS network calls.

The process aims to be simple: ‘’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.’’

We were told that, 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.
