Abstract: Methods, apparatuses and systems for user-plane congestion management are provided. Among these method, apparatuses and systems is a method, implementable by a base station (and/or a serving gateway), for mitigating user plane congestion. The method may include sending a congestion indication to a core network; receiving a general packet radio system (GPRS) tunneling protocol (GTP) packet including an first internet protocol (IP) packet associated with a first flow within a bearer; obtaining, from a header of the GTP packet, an indicator indicative of a priority of the IP packet, wherein the indicator was inserted into the header of the GTP packet by the core network responsive to the congestion indication; and dropping any of the GTP packet and the first IP packet on condition that a priority of a second IP packet associated with second flow within the bearer takes precedence over the priority of the first IP packet.
