Method and apparatus for detecting and managing user plane congestion

摘要

A method and apparatus for managing user plane congestion in a network are disclosed. A method performed by a wireless transmit/receive unit (WTRU) for user plane congestion in a network includes receiving an indication from the network that user plane congestion exists in the network, transmitting a request for the network to provide a lower Quality of Service (QoS) level for a particular service based on the indication, and observing a decrease in user plane QoS based on the transmitted request.

主权项

1. A method, performed by a wireless transmit/receive unit (WTRU), for managing user plane congestion in a network, the method comprising:
provisioning the WTRU with a plurality of application-specific congestion control categories, including a highest ranked application-specific congestion control category and a lowest ranked application-specific congestion control category, wherein the highest ranked application-specific congestion control category includes one or more operator identified applications subject to a least amount of restrictions, and wherein the lowest ranked application-specific congestion control category includes one or more operator identified applications subject to a most amount of restrictions; receiving congestion control information for each of the plurality of application-specific congestion control categories from the network, wherein the congestion control information includes a time period during which access to the network is restricted; determining not to attempt to access the network for any of the operator identified applications of the lowest ranked application-specific congestion control category based on the congestion control information for the lowest ranked application-specific congestion control category; and transmitting a request for access to the network for at least one of the operator identified applications of the highest ranked application-specific congestion control category during the time period in which access to the network is restricted for the lowest ranked application-specific congestion control category.
