Abstract:
1. A method for supporting traffics with different Qos by a High Speed Downlink Packet Access System, wherein, the method for supporting comprising the steps of: step a, setting attributes of Qos by a Core Network based on contracts and characteristics of several services, when the traffics with several different attribute requirements of Qos require to be serviced at the Core Network side of the High Speed Downlink Packet Access System, and transferring values of the attributes of Qos to a Radio Access Network Application Part of a Service Radio Network Controller via a Radio Access Bearer Service Assignment Request; step b, mapping the attributes of Qos of the traffics onto parameters that are operable by a Radio Link Control layer, a High Speed Media Access Control layer, and a physical layer by the Service Radio Network Controller, wherein the parameters that are operable by the Radio Link Control layer are the mapped parameters of Qos of logical channels, the parameters that are operable by the High Speed Media Access Control layer are the mapped parameters of Qos of transport channels, and the parameters that are operable by the physical layer are the mapped parameters of Qos of physical channels; step c, setting the parameters of the logical channels that can be set in its own layer by the Radio Link Control layer of the Service Radio Network Controller, wherein the setting of the channels and the setting of the associated parameters are informed to a Mobile Station via a Radio Bearer Service Setup signaling; step d, transferring the parameters of the transport channels and the mapped parameters of the physical channel that can not be set by the Radio Link Control layer, by the Service Radio Network Controller to the High Speed Media Access Control layer and physical layer at the Base Station via a Radio Link Setup Request signaling, allowing the High Speed Media Access Control layer and the physical layer to set the parameters that can be set in their own layers; step e, setting up data queues corresponding to different transport channels on an Interface Iub/Iur for storing different attributes of Qos for different Mobile Stations by the High Speed Media Access Control layer at the Base Station based on the received parameters of the transport channels, attribute requirements of the transport channels are thus the attribute requirements of the data queues; step f, setting a controlled parameter table of a queue operation in a scheduling method by the High Speed Media Access Control layer at the Base Station based on the attribute requirements of the data queues wherein, a queue scheduling method performs a data scheduling based on the controlled parameter table to ensure the attribute requirements of Qos of the transport channels.
