4.1 High-level architecture

[Editor’s note: description of interaction between an iRTC client in terminal and the network that shows the paths of user data and signaling, as in Figure 4.1 of TS 26.114]

4.2 iRTC client in terminal

[Editor’s note: description of functional components of a generic iRTC client in terminal, as in Figure 1 of TS 26.110 and Figure 4.2 of TS 26.114]

4.3 Web real-time communication

The iRTC client supports a subset of WebRTC, which enables real-time communication via application programming interfaces (APIs), supporting audio, video, and generic data to be sent between peers [x2]. Functionalities of WebRTC are available as JavaScript APIs for browsers, and libraries for applications [x8]. Information on use cases and requirements of WebRTC can be found in [x3].
