Content for TR 22.873 Word version: 18.0.0
1 Scope p. 6
The present document studies new scenarios (e.g. AR/VR communication) for IMS Multimedia Telephony service, identifies potential service requirements, and identifies additional potential requirements on 5G system.
This document also does a gap analysis to existing requirements in 3GPP to identify potential requirements for introduction into 3GPP.

4 Overview p. 7
With the evolution and capability enhancement of telecommunication system, telephony service has evolved from CS voice call to IMS multimedia telephony service. Nowadays 3GPP has introduced new network capabilities and new types of devices (e.g. AR/VR devices, robot, etc.), which can bring promising improvements to IMS multimedia telephony service.
XR (an umbrella term for different types of realities, such as AR/VR) technologies have proven themselves to be valuable additions to the fields of digital entertainment, information and workspace.
While more and more individual consumers enjoy MMTEL services across the globe, MMTEL services become popular also among business customers. There are several primary business functions that organizations use MMTEL services for, including internal communication, talking with prospects (sales call), contacting current customers and clients, customer support, and contact centre (or call centre) activities. While business customers consider the MMTEL services offer attractive features to their business, they also experience some practical issues that may benefit from support from the 5G system.
