Huawei Successfully Complete Voice Interoperability Test for LTE TDD to CDMA Based on Qualcomm Snapdragon Processor

[Shenzhen, China, July 26, 2013]: Huawei, a leading global information and communication technology (ICT) solutions provider, completed an end-to-end voice interoperability test for LTE TDD to CDMA, using the Qualcomm® Snapdragon™ 400 (8X30) processor and its solutions for CSFB (Circuit Switched Fallback) and eCSFB (Enhanced CSFB). Qualcomm Snapdragon is a product of Qualcomm Technologies, Inc., a wholly-owned subsidiary of Qualcomm Incorporated.

CSFB and eCSFB voice solutions are significantly important during the initial deployment of LTE networks. As operators continue to prepare for a smooth evolution to VoLTE, these solutions allow for users to seamlessly enjoy high-speed data services in conjunction with high-quality CDMA voice services without any adverse impact on overall user experience.

Kevin Wu, President for CDMA/LTE Wireless Networks at Huawei, said, “This successful test is a milestone for the commercialization of LTE voice technologies. It gives CDMA operators more choices for smoothly evolving to a wholly integrated LTE system, and reaffirms Huawei’s commitment to protect existing investments and improving the operational efficiency of multi-mode and multi-frequency networks.”

In early 2012, Huawei and Qualcomm jointly successfully completed a voice interoperability test for LTE FDD to CDMA.

Huawei’s solutions for CSFB and eCSFB are a part of the company’s SoftMobile suite of solutions that builds upon the successful foundation of SingleRAN 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 MBB business models.
