ZTE Corporation (ZTE) has announced successful completion of end-to-end voiceover TD-LTE (VoTD-LTE) call in partnership with China Mobile and Marvell Technology Group. The call was carried out using 5-mode and 13-band smartphones powered by Marvell’s chipsets.
Guangzhou was an important step toward future commercial deployment. This breakthrough in Guangzhou will help accelerate the adoption of voice services on TD-LTE networks, and usher in the TD-LTE full-service era, aligning the TD-LTE industry with the FDD-LTE industry. This deployment will also lead to development of mobile devices, TD-LTE wireless networks and IMS platforms.
For operators, VoLTE enables integration of data and voice services in a network, helping operators reduce complexity of Operation Support System(OSS), and achieve greater efficiency.
As of early 2013, ZTE had established TD-LTE field trials and commercial networks for 48 leading operators in 33 countries, including deployments in Europe, India, CIS, Asia-Pacific, and Southeast Asia. Therefore, VoLTE is considered as the ultimate goal of evolution of LTE voice solution.
