Handling user plane congestion in a wireless communication network |
摘要 |
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 congestion notifications from a plurality of PGWs and/or SGWs. 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. |

1. A mobility management entity (MME) comprising:
communications circuitry configured to communicate with a plurality of serving gateways (SGWs) and a plurality of packet data network gateways (PGWs) of an evolved packet core for a wireless communications network; and management circuitry coupled to the communications circuitry and configured to:
receive, via the communications circuitry, a proactive PGW congestion notification from individual PGWs of the plurality of PGWs indicating a level of congestion for respective PGWs;manage access to the PGWs by a user equipment of the wireless communications network based on the received proactive PGW congestion notifications; andproactively transmit to the UE a notification to indicate high network congestion based on the levels of congestion of the PGWs. |
