Embodiment Construction

[0035] The present invention aims at the deficiency of the flow control algorithm based on queue priority, considers the situation of Iub port bandwidth competition, improves the algorithm, makes the flow control of Iub port basically consistent with the scheduling of MAC-hs, and improves the system performance . The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0036] The invention perfects the deficiency of the current flow control algorithm, and proposes a solution capable of efficiently utilizing the bandwidth of the Iub port. The meaning of "efficient utilization" means: the queues that need to release the bandwidth of the Iub port can be released in good time, and the queues that need to allocate the bandwidth of the Iub port can obtain bandwidth in a timely manner. In order to achieve this goal, the solution proposed by the present invention is based on the scheduling and sorting results of MAC...

Abstract

The invention discloses a flow-control method and system for Iub port band-width in a high speed descending packet access system, including: determining queue state of each queue, according to priority and receiving and transmitting data state of each queue; allocating band-width resources to the queue according to the queue state of each queue. The invention overcomes insufficiency of current flow-control algorithmic, so that the queue required for releasing Iub port band-width can timely release band-width, and the queue required for allocating Iub port band-width can timely obtain band-width.

Description

technical field [0001] The invention relates to the communication field, in particular to a flow control method and system for Iub port bandwidth in an HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access) system. Background technique [0002] The 3GPP 25.435 protocol (Release 5) stipulates that in the HSDPA system, the RNC (Radio Network Controller, radio network controller) notifies the NB (NodeB, base station) of a MAC-d (Medium Access Control-Dedicated , dedicated medium access control) flow (flow) in the data buffer size of each priority (each CAPACITY REQUEST control frame can only carry the information of one priority data in MAC-d flow), apply to NB to send data; NB Allocate capacity to RNC through "CAPACITY ALLOCATION" control frame. According to the parameters stipulated in the agreement, there are three main factors affecting the flow of Iub port: [0003] 1. The data volume of each priority data buffer of RNC MAC-d flow; [0004] 2. MA...
