Abstract
A residential gateway (RG), e.g., a 5G-RG, indicates its support for ECN marking for L4S in uplink and/or downlink via a PDU session request message, e.g., a PDU session establishment request message, communicated from the RG via a 3GPP radio access network (RAN) to a core network, e.g., a 5GC. The indication, in some embodiments, is provided in either: a Session Management (SM) capability field, e.g., a 5GSM capability field, or as a new indication, which is included as part of a N1 SM container. A RG may, and sometimes does, determine congestion in its buffers/queues and perform ECN marking and report if traffic congestion is being experienced within its own buffers/queues for uplink and/or downlink traffic. In some such embodiments, both an RG and a RAN can, and sometimes do, perform ECN marking for L4S simultaneously in both directions (i.e. uplink and downlink).
