Abstract

The invention discloses a packet scheduling method in high speed downlink packet access HSDPA network. The method includes: A. according to channel quality indication CQI information of priority queuing which is reported by presidial user equipment UE in current transmission time interval TTI, downlink average speed of PQ packet data transmitted to UE, data bulk of PQ packet data cache stored in RNC and scheduling priority index for PQ which is arranged by RNC, a Node B obtains PQ priority; B. the PQ priority sequence is different UE distribution radio resource, the Node B transmites packet data to UE through distributed radio resource. The method not only guaranteens system throughput and UE impartiality, but also guaranteens packet data QoS level and UE priority.

Description

Technical field

[0001] The invention relates to a method for wireless resource scheduling of packet data in a high-speed downlink packet access (HSDPA) network, and in particular to a method for packet scheduling in a HSDPA network. Background technique

[0002] The structure of a radio access network (RAN, Radio Access Network) is shown in Figure 1. The RAN includes one or several radio network subsystems (RNS). An RNS consists of a Radio Network Controller (RNC) and one or more NodeBs (NodeB). The interface between RNC and CN is the Iu interface, and NodeB and RNC are connected through the Iub interface. Within the RAN, RNCs are interconnected through the Iur interface to allocate and control the radio resources of the NodeB connected to or related to it. The NodeB transmits the data packets transmitted from the Iub interface to the user equipment (UE) through the Uu interface or transmits the data packets transmitted from the Uu interface to the RNC through the Iub. The NodeB ...
