Latency Becomes a New Indicator for User Experience Measurement
[Shanghai, China, March 2, 2018] Huawei and NetEase have jointly completed a latency test at Huawei Lab for online games that utilize the latest low-latency solution. The solution includes key technologies complying with 3GPP Release 15, such as Short TTI. Test results show that the loopback latency over the air interface dropped to 2 ms, compared with 20 ms on LTE networks that do not use the low-latency solution. The average E2E latency dropped to 33 ms, a decrease of more than 30%, sufficient to provide a smooth, zero-freeze gaming experience. The test proves that low-latency technology can improve the experience of interactive gaming services. It also demonstrates the in-depth insights and innovation capabilities of both parties in improving user experience.
Recent years have witnessed the rapid development of Internet gaming, with games such as Rules of Survival attracting more than 100 million registered gamers worldwide. Gamers are extremely sensitive to network speed and latency.
3GPP Release 15 protocols include Short TTI, a crucial low-latency LTE technology. This technology shortens the scheduling period to decrease the latency over the air interface. The low latency that LTE evolution offers enables new low-latency services to be rolled out for the LTE era. In addition, a lower latency on the wireless side facilitates a futher reduction in E2E latency. The introduction of Short TTI and other technologies decreased E2E gaming latency to 33 ms, a reduction of more than 30%, according to the test result. This reduced latency assures a smooth gaming experience for players.
"The NetEase gaming team has been dedicated to providing players with a superlative gaming experience," said Xiang Lang, Senior Marketing Manager at NetEase Games. “We are happy to have this chance to work with Huawei on verification of how advanced telecommunication technologies can improve the gaming experience. We believe that our close collaboration will allow us to make further contributions to the entire game industry, explore more game designs, and enhance inter-server gaming. We welcome all types of innovative technologies, any technology that can help us improve user experience and promote the development of the Internet industry."
Veni Shone, President of Huawei’s LTE Product Line, commented, "The joint test by Huawei and NetEase has demonstrated that Short TTI improves the experience for real-time first-person shooters. In addition, Short TTI also makes it possible for industrial control, remote medical care, and drone control, and other services to be deployed on LTE networks. As voice over LTE service becomes increasingly popular, most operators have positioned the LTE network as the most important infrastructure network, one that can carry a full range of services. We will devote persistent effort to further developing LTE technologies and providing consumers with a fully connected world, a world that is always renewing itself and expanding into new services."
