The H.248 Context model for a WebRTC call in Figure 6.2.10.6.2.1 is assumed. However, the example flow in this clause focuses on the WebRTC data channel part only. Thus, only H.248 Streams S1 (for de-aggregation of multiple data channels) and S2 (for MSRP traffic) are indicated subsequently. Furthermore, there is an additional termination T3 towards the IMS core network to handle DTLS. Figure 6.2.22.3.2.1 shows the message sequence chart example for the WIC originated procedure to establish a WebRTC data channel with media plane optimization following the procedures in clause 5.20.3.2.
