Abstract
The present invention discloses a method for reducing the loss of data packets in an updating process of a service subzone of a high-speed downlink shared channel (HS-DSCH). In the method, after the information that a user begins to update the service subzone of the high-speed downlink shared channel is received in the updating process of the service subzone of the high-speed downlink shared channel, the dispatching priority of the user is adjusted upwards, the user priority adjusted upwards always acts until the updating process of the service subzone of the downlink shared channel of users is ended, and the user's data in the buffer of high-speed medium access control (MAC-hs) in the source service subzone can be sent out more before the restoration of the high-speed medium access control. The present invention causes more user's data to be sent out in the updating process of the service subzone of HS-DSCH by adusting the user's dispatching priority upwards in the updating process of the service subzone of the high-speed downlink shared channel, and accordingly, the loss of the user's data packets is reduced.
Description
Technical field
The high speed downlink packet that the present invention relates in Wideband Code Division Multiple Access (WCDMA) (WCDMA) system inserts (HSDPA) technology, specifically, relates to a kind of minimizing data-bag lose in renewing course of high-speed downward sharing channel service residence method.
Background technology
HSDPA is a kind of technology of carrying out high speed data transfer in the down link of WCDMA system that 3GPP proposes in the agreement of its R5 version, and what carry this transfer of data is exactly the high speed descending sharing channel (HS-DSCH) that user (UE) and sub-district are set up.In the WCDMA system, the user can connect with a plurality of sub-districts, but the user can only receive the HS-DSCH data from a sub-district, and this sub-district is called as the HS-DSCH Serving cell.
The HS-DSCH Radio Link is based upon the better quality of signal sub-district, can obtain higher throughput, therefore the signal quality variation of working as user's HS-DSCH Serving cell, and when other cell signal quality grows that connect with the user are arranged, switchover policy according to HSDPA, according to certain thresholding and time delay setting, the sub-district that the HS-DSCH Serving cell is connected from original service cell updating to other and user.The user is when carrying out the HS-DSCH service cell updating, and source Serving cell and target serving district may belong to same base station (NodeB), also may belong to different NodeB.The user carries out the HS-DSCH service cell updating between different NodeB schematic diagram as shown in Figure 1.S among Fig. 1 represents the cell-of-origin, t represents Target cell, MAC-hs among Fig. 1 is the access control of high speed medium, all users' HS-DSCH data need be kept in the buffer memory of MAC-hs in the sub-district, adopt certain dispatching algorithm that each user is dispatched and sent to each user's data in the MAC-hs buffer memory then.
The user carries out the HS-DSCH service cell updating between different NodeB idiographic flow is as shown in Figure 2:
1, the source NodeB of radio network controller (RNC) under the Serving cell of original carrying HS-DSCH sends radio link reconfiguration and prepares (Radio Link Reconfiguration Prepare) message, prepares the resource that deletion HS-DSCH takies in the cell-of-origin.
2, source NodeB replys radio link reconfiguration ready (Radio LinkReconfiguration Ready) message to RNC.
3, RNC sends Radio LinkReconfiguration Prepare message to the target NodeB of the target serving district that comprises HS-DSCH, to increase the HS-DSCH resource in target NodeB.
4, target NodeB is replied Radio Link Reconfiguration Ready message to RNC.
5, RNC sends radio link reconfiguration to source NodeB and submits (Radio LinkReconfiguration Commit) message to, comprises activationary time in the message, and in the activationary time moment corresponding, source NodeB stops to send data, and the MAC-hs of source NodeB resets.
6, RNC sends Radio Link Reconfiguration Commit message to target NodeB.Comprise activationary time in the message, in the activationary time moment corresponding, target NodeB begins to send data.
7, RNC sends physical channel and reshuffles (Physical Channel Reconfiguration) message to the user, message comprises activationary time and the MAC-hs indication that resets, after UE received Physical ChannelReconfiguration message, the transmission physical channel was reshuffled and is finished (Physical ChannelReconfiguration Complete) message to RNC.
8, in the activationary time moment corresponding, user's MAC-hs resets, and stops to receive data from the Serving cell of original carrying HS-DSCH, begins to receive data from the target serving district of HS-DSCH.
In above-mentioned flow process and since in the HS-DSCH service cell updating process under the Serving cell of source the MAC-hs entity of NodeB need reset, thereby cause being stored in loss of data in the MAC-hs entity buffer memory of this NodeB.For the business that high level adopts non-affirmation mode to transmit, the loss of data of NodeB means that receiving terminal can not receive complete data, causes the decline of quality of service, for example produces the discontinuous of video pictures, phenomenons such as the interruption of sound.Adopt the affirmation mode to transmit the business of data for high level, the loss of data of NodeB means that the RNC needs send to data in the MAC-hs entity of the NodeB that newly sets up HS-DSCH by the interface between the NodeB under RNC and the new Serving cell again, cause the increase of data volume on the interface and cause the waste of bandwidth, in addition, because RNC can only could confirm behind the status report of receiving receiving terminal (UE) which data is not correctly sent to UE by source NodeB, indication according to status report resends those data of being lost to new NodeB then, thereby brings extra time delay.
Summary of the invention
In view of this, purpose of the present invention is exactly to reduce the data-bag lost that is caused when the user carries out the high-speed downward sharing channel service residence renewal between different base station, improves service quality.
The present invention is achieved through the following technical solutions:
