Problems solved by technology

[0040] At present, the published patents and documents on the HSDPA flow control algorithm mainly involve the description of the basic process of flow control, but there is no detailed description of the principle by which Node B sends capacity allocation control frames to RNC and the specific capacity allocated. , the dynamic control of the Iub port traffic cannot be realized, resulting in the Iub port is prone to congestion, the Uu port transmission efficiency is low, and resources cannot be fully utilized

Embodiment Construction

[0088] The basic thought of the present invention is: according to the variation of priority queue data amount and data amount and the Iub port flow that has been allocated at present, dynamically control Node B to send the opportunity of capacity allocation control frame and the concrete flow of allocation to RNC.

[0089] This embodiment is described as a scheduling method of a high-speed downlink packet access (HSDPA) communication system, but the present invention is also applicable to the above-mentioned scheduling method supporting high-speed downlink packet access (HSDPA) wireless mobile communication technology Cases, such as a Code Division Multiple Access 2000 (CDMA2000) communication system, a Time Division Duplex-Synchronous Code Division Multiple Access (TD-SCDMA) communication system or a Wideband Code Division Multiple Access (WCDMA) communication system.

[0090] The present invention will be further described in detail below in conjunction with accompanying dra...

Abstract

The control method includes following steps: setting up threshold value of data quantity in priority queue of Node B; after receiving trigger event, Node B detects data quantity in priority queue, and determines relation between the data quantity and the threshold value; based on relation between the data quantity and the threshold value, Node B sends control frame of capacity assignment to RNC. The method can reduce frequency for sending control frames so as to realize more accurate and effective control on flux of Iub port.

Description

technical field [0001] The invention relates to the communication field, in particular to a flow control method of an Iub port. Background technique [0002] 3GPP Release 5 introduces a high-speed downlink packet access (High-Speed ​​Downlink Packet Access, HSDPA) technology, which is used to increase the data transmission rate of the downlink. In HSDPA, a high-speed media access control (MAC-hs) entity needs to be added to the base station (Node B) to be responsible for fast scheduling and management of data. Its main functions include: Iub (the interface between the radio network controller (RNC) and NodeB) Medium data flow control; cache of packet data in priority queue; packet scheduling and priority processing; fast packet scheduling mechanism. Data arriving from the radio network controller (RNC) must first be cached in the MAC-hs, waiting for scheduled transmission. [0003] The MAC-hs entity is at the Media Access Control (MAC) layer. A medium access control (MAC)...
