Abstract
The method divides indicator value of channel quality of user into grades. Each grade is corresponding to up threshold, low threshold of each media access control in high-speed (MAC-hs) queue. The method calculates dispatching speed of data of radio link control (RLC) layer in radio network control (RNC). The invention changes calculation of fixed up threshold, low threshold of MAC-hs queue to variety dependent on user's channel quality. Being able to load change of user's mobility and cell, flow control method provides advantages: reducing discarded data quantity greatly compared to current method when switching user's cell occurs; shortening detaining time of user's data in MAC-hs, and reducing possibility of resetting radio load supporting service in RLC layer when channel environment is poor; guaranteeing expectant high speed rate.
Description
Technical field
The present invention relates to high speed descending sharing channel (HS-DSCH) technology in Wideband Code Division Multiple Access (WCDMA) (WCDMA) system, specifically, relate to a kind of high speed downlink packet and insert (HSDPA) flow control method.
Background technology
The Release5 of WCDMA system version is supported the HS-DSCH channel, and this channel can provide the downlink grouped data of two-forty to send.In HS-DSCH channel data transmission process, there is a high speed media access control (MAC-hs) entity in (NodeB) in the base station, this entity has been set up the metadata cache space for the user that each is carried on HS-DSCH, being used to store this user need be in the data of HS-DSCH channel transmission, and these data are stored in the buffer memory of MAC-hs with the form of formation.Be used to control the HSDPA flow control method of MAC-hs entity buffer memory, according to certain principle, the wireless chain control layer (RLC) in the decision radio network controller (RNC) sends a certain amount of data with special speed to the data queue of user in the MAC-hs buffer memory.
The HSDPA flow control method has determined the data volume of each user's queue for storing, if the data deficiencies of storage may can not provide enough data when needs send mass data, causes transmission rate to descend; If then can there be following problem in the overabundance of data of storage: (1) is taking place can to cause too much loss of data when switch the sub-district, and then also causes call drop easily; (2) cause each data cell long, bring long propagation delay time, influence service quality at the residence time of NodeB; (3) make the propagation delay time of data cell be in uncertain state, bring difficulty for relevant parameter configuration.
Therefore, a good HSDPA flow control method need be controlled the length of data queue of MAC-hs effectively, with the service quality that guarantees that simultaneously high transmission rate is become reconciled.
Existing HSDPA flow control method generally can decide the data total amount of RLC to MAC-hs formation transmission for the buffer memory total amount that each user distributes according to the MAC-hs of NodeB, and specific practice is:
Dispose a plurality of quene thresholds, according to the descending sort of threshold value size: max threshold, middle thresholding 1 ..., middle thresholding n, and minimum threshold, wherein max threshold generally according to every user the cache size that can distribute dispose;
When queue length was lower than a certain thresholding, the HSDPA flow control method just sent data to the RNC request, and the speed that sends data is generally calculated with { (cache size-one-level thresholding above the current queue length)/scheduling time };
When queue length is higher than max threshold, just send indication to RNC, require to stop immediately sending data.
In existing HSDPA flow control method, quene threshold is fixed, and always fills MAC-hs formation buffer memory fuller, can not adapt to the variation of wireless environment and user's mobility:
If the max threshold of configuration is smaller, when channel circumstance is reasonable, can not provide enough data to send so, make user's transmission rate can not reach the maximum of expectation;
If the max threshold of configuration is bigger, when the channel circumstance variation, lot of data is stored in the MAC-hs formation for a long time so, can cause the re-transmission of RLC to increase, even reset and call drop; When the sub-district that takes place to switch, particularly switch in the sub-district was in different base stations, the data in the formation all can be dropped, and formation is long more, and the data that abandon are many more, and the possibility of call drop is also big more.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of HSDPA flow control method that wireless channel changes that adapts to, channel quality indication (CQI) value according to user report, when wireless channel environment is reasonable, increase the MAC-hs queue length, the scheduling mass data satisfies the transmission demand so that sufficient data to be provided; When wireless channel environment is poor, reduce the MAC-hs queue length, the data volume that reduces to dispatch avoids mass data to be stranded in the formation.
