Shulou(Shulou.com)11/24 Report--

On May 16, 2023, China Mobile, together with Qualcomm Technology, announced that the two sides have joined forces with leading handset manufacturers including vivo, Xiaomi and ZTE to complete the end-to-end business verification of new 5G calls based on IMS Data Channel (data Channel, hereinafter referred to as DC) in the laboratory and outfield environment, and for the first time to use Snapdragon ®5G modems and RF systems to implement a complete IMS DC underlying protocol stack for new calls on the baseband side. This cooperation will help promote the commercial use of China Mobile's new 5G call business and inject new vitality into 5G development and innovation.

This time, under China Mobile's new call laboratory and outfield environment, the engineering and technical teams from Qualcomm, vivo, Xiaomi and ZTE, using vivo sub-brand products iQOO 11 Pro, Xiaomi 13 and nubia Z50 equipped with the second generation Snapdragon 8 mobile platform, successively completed the end-to-end business verification of IMS DC based on China Mobile's pilot SDK, and realized the transmission of real-time interactive information on the basis of traditional audio and video communications. In addition, in the laboratory, Qualcomm Technology also completed the debugging of the IMS DC underlying protocol stack based on the test terminal equipped with Snapdragon X705G modem and RF system, together with the network side, bringing the industry's first complete new call IMS DC underlying protocol stack based on the baseband side, improving the reliability of the calling service. This verification and debugging lays a technical foundation for business innovation, terminal and chip industry support for follow-up 5G new calls.

5G new call is a 5G iconic application first put forward by China Mobile, which is an upgrade of traditional audio and video calls. The introduction of the new IMS DC can support the transmission of all-media data such as pictures, expressions, menus, AR / VR, etc., and provide innovative call enhancement services and rich real-time interactive applications, such as interesting calls, content sharing, real-time translation, etc., bringing users a visual, multimedia, strong interactive call experience. As an important carrier of enterprise communication services, 5G new calls can also provide enterprises with value solutions for a variety of call business models in the form of business upgrading. support enterprises to bring visual menus, business cards, remote ultrasound, intelligent maintenance and other diversified use cases, empower government, medical, industry and other industries, helping to build a new pattern of industry mutual benefit, opening up and win-win situation.

Wang Hengjiang, deputy general manager of China Mobile Terminal Corporation, said: "the new 5G call, first proposed by China Mobile, aims to create a new ecology of open call applications. It requires the participation of platforms, terminals, chips, application developers and service providers and other parties in the industry chain. This time, we have successfully carried out end-to-end business verification of 5G new calls in conjunction with a wide range of industry chain partners, paving the way for commercial and industrial prosperity of 5G new calls. "

Sun Gang, vice president of product marketing at Qualcomm Technologies, said: "with the scale deployment of 5G network and the continuous evolution to 5G-Advanced, 5G new calls based on IMS DC will continue to move forward. As an active and continuous participant in China Mobile's new 5G call plan, Qualcomm Technology Company immediately participated in the discussion of the relevant technology plan, which contributed to the maturity and landing of the 5G new call technology. We will, as always, support the verification and promotion of China Mobile's commercial SDK, cooperate with terminal manufacturers to launch commercial terminal products at an early date, and join hands with industrial partners to seize the broad opportunities brought about by the commercial deployment of IMS DC. "

Gong Haihui, senior system engineer of vivo Communications Technology Department, said: "compared with traditional voice services, 5G new calls have obvious advantages such as faster, clearer, smarter and wider. The verification of 5G new call business this time shows that we are constantly turning technology accumulation into an industry driving force. Vivo, together with ecological partners such as China Mobile and Qualcomm Technology, jointly promote the development of 5G new calls, closely coordinate, continue to explore and optimize application scenarios, and make 5G vitality bloom again. "

Zhang Guoquan, deputy general manager of Xiaomi Mobile phone Software Department, said: "as the carrier and service entrance of applications, terminal products that support 5G new calls are an important factor in promoting 5G new calls to a new level and large-scale popularity. The end-to-end business verification of 5G new calls based on IMS DC shows the results of Xiaomi's cooperation with operators and industry parties, including China Mobile and Qualcomm, to promote the development of 5G new calls to a new stage. We will actively explore new functions and modes of call business under the 5G network, bring more innovative 5G new phone applications to the industry and consumers, and draw a beautiful blueprint for 5G new calls. "

Zhang Lei, vice president and general manager of ZTE's flagship products, said: "with its profound accumulation in the voice field, ZTE has actively explored and practiced the standard research, specification formulation and pilot verification of 5G new calls. As a practitioner of 5G new call innovation, our end-to-end business verification with partners such as China Mobile and Qualcomm Technology will strongly support the commercial and large-scale deployment of 5G new calls. In the future, we will work with more partners to create terminals that support 5G new calls, develop 5G new calls industry, expand new business, and create new experiences. "
