Abstract
Methods, apparatus, and systems that can be implemented to associate User Datagram Protocol (UDP) based connection identifiers with appropriate Quality of Service (QoS) flows are disclosed to enable Access Traffic Steering, Switching and Splitting functionality at lower layers and to allow accurate measurements of Round-Trip Time for all traffic on a session. In one example aspect, a wireless communication method includes determining, by one or more nodes in a core network for a session that comprises at least one QoS flow, at least two identifiers identifying two connections associated with the at least one QoS flow. The two connections are established according to a UDP based protocol. The method also includes establishing, by the one or more nodes in the core network, a mapping between the at least two connection identifiers and the at least one QoS flow.
