5G news is here! What do you think of text messages with audio, video and location?

Nowadays, 5G has been in commercial use for two years, and 5G smart phones are becoming increasingly popular. In the 5G era, what changes have been made to text messages in mobile phones? In addition to the functions of sending and receiving traditional texts, 5G messages can also receive multimedia content such as pronunciation videos, locations, and sliding cards. The pace of 5G news is getting closer. How will it affect our lives?

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

Powerful, 5G news breaks imagination

"I think 5G messaging is the most likely to be the first large-scale application of 5G native innovative business form." Lu Di said that 5G messaging is RCS (Rich Communication Suite), that is, rich media. In terms of content form, in addition to text and pictures, 5G messages can also provide multimedia content such as audio and video, location, and sliding cards. From a formal point of view, 5G messaging has more capabilities than traditional SMS services. It uses traditional SMS as an entry point, has an embedded card, sends real-time location, completes digital payment and other functions. Individuals do not need to open the APP, and can interact with the chat robot through the mobile phone SMS portal.

 

Technology empowered, 5G news is developing rapidly

Ludi believes that the development of 5G messaging is inseparable from the technical support of the three levels of network, terminal and IT.

 

The network layer mainly uses IMS technology. IMS technology is a hierarchical, open and converged communication core network constructed on operator networks using IP technology. It can reduce the waiting time for users to communicate across operators, improve the quality of calls between networks, and provide users with richer multimedia services. . Lu Di said, “IMS is one of the important technologies for realizing 5G messaging. At present, my country’s three major operators have completed the deployment of the IMS network interconnection and interoperability of the national mobile communication network and officially provide services to users.”

 

At the terminal level, Ludi said: "5G messaging SDK is the core capability suite at the terminal level, and only terminals with 5G messaging SDK have the ability to receive 5G messages." At the IT level, Ludi emphasized: "5G news is closely related to the development of AI technology." As an industry-oriented message service platform, the MaaP platform requires a combination of chatbot, NPL (Natural Language Processing), AI and other technologies.

Bright prospects, 5G news brings new challenges

Currently, users who use 4G terminals still account for the majority. Can 4G terminals receive 5G messages? Talking about this issue, Ludi said that 5G messages have an information "fallback" mechanism, and 5G messages received by 4G terminals are smart short messages. Similarly, 3G and 2G terminals can also receive 5G messages, but the form will be different.

 

Therefore, 5G messages, as a strong reach application, will play an important role in government affairs, meteorology, banking, and media reporting. As for whether the arrival of 5G news will have an impact on some apps, Ludi believes: “APP is an organization form of information in the 4G era. 5G news has many functions, omitting users from searching, downloading, and installing certain apps in the app market. Therefore, 5G messaging is likely to become a product form that replaces APP in the 5G era."
