Abstract  Abstract

Embodiments of the present disclosure describe devices methods computer-readable media and systems configurations for handling user plane congestion in a wireless communications network. A packet data network gateway (PGW) and/or a serving gateway (SGW) may proactively transmit a congestion notification to a mobility management entity (MME) including a level of congestion of the PGW and/or SGW. The MME may receive a request for a packet data network (PDN) connection from a user equipment (UE) and may take an action in response to the request based on the reported levels of congestion. The action may include selecting a PGW and/or SGW for the PDN connection notifying the UE that the PDN connection cannot be established and/or negotiating with the UE to terminate or modify one or more existing PDN connections in exchange for establishing the new PDN connection.
