GSMA Foundry 5G New Calling whitepaper 2023

5G New Calling: Revolutionising the Communications Services Landscape

The communication services landscape is on the brink of significant and revolutionary change. Emerging onto the scene is “5G New Calling” (5GNC), a 5G network capability that will leverage the IP Multimedia Subsystem (IMS) and introduce the potential for ultra-HD, intelligent, and interactive personal and enterprise communication services. As a result, 5GNC will vastly expand mobile operator capabilities and stimulate groundbreaking innovations within the communication domain, by opening up opportunities to developer communities to create and distribute new services and applications.

To support 5GNC, there is an emerging new ecosystem involving operators, equipment suppliers, terminal and chip vendors, industry organisations, and content producers, leading the stride in the communications services landscape revolution.

This document, produced by the 5G New Calling GSMA Foundry project team, was edited, contributed and reviewed by CMCC, GSMA, AIS, Huawei, itaú, iFlytech, UNISOC, Xiaomi, Zain Kuwait, China Broadnet, Honor, MediaTek, Meizu and OPPO, takes a look at the role 5GNC will play in the global communications landscape over the next few years following 3GPP’s Release 18.
