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.

Abstract: Aspects of the present disclosure provide techniques for end-to-end rate adaptation using radio access network (RAN) assisted rate adaptation. Particularly, when a user equipment (UE) risks operating at rates greater than the guaranteed bit rates (GBR), the UE may rely on rate adaptation mechanisms to indicate when it has exceeded the supported bandwidth such that the UE may reduce its rate accordingly. Specifically, in some examples, a network device (e.g., call session control function (CSCF) and/or policy and charging rules function (PCRF)) may configure endpoints in an end-to-end communication to operate at rates that exceed GBR based on determining that all endpoints support RAN assisted rate adaptation capability. In other examples, the network device may configure maximum bit rates (MBR) that exceed GBR for only the endpoint that supports RAN assisted rate adaptation capability.
