Methods and apparatus for supporting low latency, low loss and scalable throughput L4S through the use of UE route selection policy (URSP) rules

Abstract

A UE is supplied with one or more UE Route Selection Policy (URSP) rules which include an indicator indicating support for a “L4S” Connection Capability. The use of an L4S connection capability indicator allows a UE to obtain L4S support for application traffic data requiring L4S support. The connection capabilities option in the URSP rule or rules allows a UE to select an appropriate route selection for matching L4S connection capability. By allowing a UE to indicate that a packet or packet flow is to be matched to a PDU session which has an L4S connection capability, the UE can trigger establishment of a new PDU session to support a flow of application data packets requiring L4S support or can cause the packet flow to be assigned to an existing PDU session or trigger a modification of an existing PDU Session which supports L4S.
