5G news is coming! How to treat short messages with audio, video and location?

Nowadays, 5G has been commercialized for two years, and 5G smartphones are becoming more and more popular. In the 5G era, what changes have been made to SMS in mobile phones? In addition to the function of sending and receiving traditional texts, 5G messages can also send and receive multimedia contents such as audio and video, location and slide cards. The pace of 5G news is getting closer and closer. What impact will it have on our lives?

In response to public concerns, People's Daily invited Lu Di, an associate professor at the State Key Laboratory of Media Convergence and Communication of Communication University of China and an expert at China Telecom's 5G Media Convergence Laboratory, to answer your questions.

Powerful, 5G news breaks through imagination

"I think that 5G messaging is a native innovative business form of 5G, and it is most likely to be applied on a large scale first." Rudy said that 5G messages are RCS (Rich Communication Suite), that is, rich media. From the content form, in addition to words and pictures, 5G messages can also provide multimedia content such as audio and video, location, and slide cards. Formally, compared with the traditional short message service, 5G messaging has more capabilities. It takes the traditional short message as the entrance, and has the functions of embedding cards, sending real-time location and completing digital payment. Individuals can interact with chat bots through SMS portal without opening applications.

Technology empowerment, rapid development of 5G messages

Rudy believes that the development of 5G messages is inseparable from the technical support of network, terminal and IT.

The network layer mainly uses IMS technology. IMS technology is a layered, open and integrated communication core network built on the carrier network by using IP technology, which can reduce the waiting time of users' cross-carrier communication, improve the quality of inter-network calls and provide users with more rich multimedia services. Lu Di said, "IMS is one of the important technologies to realize 5G messaging. At present, China's three major operators have completed the deployment of IMS network interconnection of the national mobile communication network and officially provided services to users. "

At the terminal level, Lu Di said: "The 5G message SDK is the core capability suite at the terminal level, and the terminal with the 5G message SDK has the ability to receive 5G messages." At the IT level, Rudy emphasized that "5G messages are closely related to the development of AI technology". As an industry-oriented message service platform, MaaP platform needs to combine chatbot, NPL (Natural Language Processing), AI and other technologies.

The prospects are broad, and 5G news brings new challenges.

At present, users using 4G terminals still account for the majority. Can a 4G terminal receive 5G messages? Speaking of this issue, Rudy said that the 5G message has a mechanism of information "falling back", and the 5G message received by the 4G terminal is an intelligent message. Similarly, 3G and 2G terminals can also receive 5G messages, but in different forms.

Therefore, as a powerful reach application, 5G messages will play an important role in government affairs, meteorology, banking and media reports. As for whether the arrival of 5G messages will have an impact on some apps, Rudy believes: "APP is an organizational form of information in the 4G era. 5G messages have many functions, which saves the process of searching, downloading and installing some apps in the application market. Therefore, 5G messages are likely to become the product form of replacing APP in the 5G era. "
