Abstract
Described are techniques for providing, a quality of service (QoS) update from a control plane of a base station to a user plane of the base station based on a QoS event, wherein the QoS update includes information indicative of a mapping between a QoS flow and corresponding radio resources for user data transmission, storing, at the user plane, the mapping between the QoS flow and the radio resources, receiving, at the user plane, a downstream data packet of the QoS flow from a core network, and transmitting the downstream data packet in a downlink direction using the corresponding radio resources.
Claims6
A method of wireless communication, comprising:
- receiving, by a user plane of a base station from a user equipment, a data packet on a default data radio bearer (DRB), wherein the data packet includes a quality of service flow indicator (QFI);
- sending, to a control plane of the base station, a message that includes the QFI that identifies a Quality of Service (QoS) flow in response to an absence of mapping between the QoS flow and a DRB at the user plane of the base station;
- and
- receiving, by the user plane from the control plane, another message that indicates a mapping relationship between the QoS flow and the DRB.
A communication apparatus, comprising:
- a processor configured to:
- receive, by a user plane of a base station from a user equipment, a data packet on a default data radio bearer (DRB), wherein the data packet includes a quality of service flow indicator (QFI);
- send, to a control plane of the base station, a message that includes the QFI that identifies a Quality of Service (QoS) flow in response to an absence of mapping between the QoS flow and a DRB at the user plane of the base station;
- and
- receive, by the user plane from the control plane, another message that indicates a mapping relationship between the QoS flow and the DRB.
