Abstract  Abstract

Embodiments of the present disclosure describe techniques and configurations for handling a wait time in a wireless communication network when the network is determined to be congested. An apparatus may include computer-readable media having instructions and one or more processors coupled with the computer-readable media and configured to execute the instructions to send a radio resource control request message to a wireless network controller receive a response message including an extended wait time value determine upon receipt of the response message whether a back-off timer associated with the apparatus is running and determine whether to start the backoff timer with the received extended wait time value based at least in part on the determination of whether the back-off timer is running and the received wait time value is packet data network gateway (PGW) and/or serving gateway (SGW) can be transmitted includes the congestion level of the PGW and/or SGW to a mobility management entity (MME) is active congestion notification. MME can receive from a user equipment (UE) to a packet data network (PDN) connection request and can be based on the reported congestion level to take action in response to the request. the action can comprise selecting PDN connection for the PGW and/or SGW signalled to the UE is not capable of establishing a PDN connection and/or negotiating with the UE to terminate or modify one or more existing PDN connection as exchange of establishing the new PDN connection.

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.
