Abstract: A client device (e.g., user equipment or “UE”) may be configured to engage in a media communication session, such as a WebRTC session, with another client device. The client devices may separate a quality of service (QoS) specification from a QoS flow definition, to allow for separate interactive connectivity establishment (ICE) negotiation. The QoS specification may cover all segments of a connection for the media communication session. For example, QoS may be requested for a case where a server (e.g., a Traversal Using Relay Network Address Translation (TURN) server) is hosted by a mobile network operator (MNO). The QoS specification and the QoS flow description may be linked.
