What does 5g message mean?

In fact, 5G messages have nothing to do with 5G and can be regarded as enhanced short messages. The development of short messages has a great relationship with the core network. Early telephone calls were completed by circuit switching, and each user would enjoy a single link, which was called CS domain in communication. In the 4G era, there is a call technology called CSFB, in which CS is this. SMS appeared earlier and was also carried by CS domain.

RCS, also known as Unified Communications. The so-called "convergence" can be understood as the convergence of various media forms and the convergence of IP services and traditional telecom network services.

The birth and development of RCS

In 2007, a few GSMA (Global System for Mobile Communications) members proposed RCS, aiming at multimedia messaging between operators.

In February 2008, GSMA formally established the RCS project and named it "home". Since then, GSMA has released several versions of RCS and RCS-E (enhanced) specifications.

After the release of RCS, it has won the support of many operators around the world. Especially after the release of 4G LTE standard in 2008, RCS became the standard for operators to build 4G.

Also around 2008, iPhone and Android came out one after another, mobile communication entered the era of smart phones, and the mobile Internet market began to blow out.
