D2 Technologies’ (News - Alert) IR.92 VoLTE software has been licensed by chipset solution provider HiSilicon Technologies to enable carrier-grade voice and SMS over VoLTE capability on the HiSilicon LTE (News - Alert) modem chipsets and application processors for mobile devices. Together, the two companies recently demonstrated a VoLTE call in the China Mobile Interoperability Testing Lab with the Huawei (News - Alert) D2-6070 TD-LTE phone and D2’s vPort 4G software running on the HiSilicon K3V2/Balong710 LTE chipset solution.
Considering China is set to release VoLTE phones next year, thanks to a push by the government to actively pursue 4G LTE TDD deployment in the country, this announcement is timely to say the least.
The D2 vPort 4G software is actually meant to integrate directly into LTE modem ICs, which offers a significant boost for both integration and the speed of commercialization of VoLTE-enabled mobile devices. This integration into the modem chipset also means OEMs can quickly add optimized VoLTE capability, while requiring no changes to the mobile OS, as all 2G/3G voice and SMS functionality is effectively recycled for the purpose of enabling VoLTE.
Additionally, vPort 4G offers an advanced IMS API option that allows for embedded RCS, IR.94 video calling and IP Wi-Fi calling — all running on the mobile application processor and integrated natively into the mobile OS.
The HiSilicon Balong 710 wireless terminal chipset solution, meanwhile, is the world’s first such chipset to support LTE Cat 4 150Mbps and 3G Dual carriers with MIMO 84Mbps in the downlink.
"This partnership and successful demonstration are both significant milestones for the mainstream adoption of IMS-based communications in the mobile industry," said Doug Makishima (News - Alert), chief operating officer for D2 Technologies, in a statement. "HiSilicon, Huawei and China Mobile are at the forefront of LTE and VoLTE innovation on behalf of operators, phone manufacturers and mobile consumers. We are pleased that an industry leader such as HiSilicon has selected our software platform to help bring advanced VoLTE products to the market."
