Abstract

See full text

A core network delivers two sets of quality of service (QoS) parameters to an access network device. The access network device selects one of the two sets of QoS parameters, and indicates the selected set of QoS parameters to the core network. An air interface rate required by the set of QoS parameters can be supported by a radio access network (RAN). In this way, a QoS parameter applied to a related user equipment (UE), a related bearer, a related packet data unit (PDU) session, or a related QoS flow can be effectively determined, and a hardware capability of an LTE base station does not need to be upgraded. In addition, the core network may set, based on a QoS parameter selected by a RAN side, a corresponding QoS management policy such as a rate adjustment policy, to facilitate data transmission between UE and the core network.
