Abstract
The embodiment of the invention provides an uplink access control method, a base station and user equipment (UE). The uplink access control method comprises the steps that a base station sends control information to the UE through an E-AGCH (Enhanced-Access Grant Channel), wherein the control information carries an identifier of the UE and a public enhanced special channel resource number used by the UE so that the UE sends uplink information by using a public enhanced special channel resource corresponding to the resource number after determining that the control information is the control information sent to the UE according to the identifier of the UE; and the base station receives the uplink information sent by the UE through the public enhanced special channel resource. According to the embodiment of the invention, the compatibility that the base station controls the UE under a CELL-FACH (CELL-Forward Access Channel) state for uplink access is enhanced, and the downlink code resource can be saved through the identifier of the UE sent to the UE by the enhanced special E-AGCH and the public enhanced special channel resource number used by the UE.
Description
Technical field
The embodiment of the invention relates to communication technical field, relates in particular to a kind of up connection control method, base station and subscriber equipment.
Background technology
At existing cell forward access channel (Cell Forward Access Channel; Hereinafter to be referred as: CELL-FACH) in the enhanced uplink technology, (the User Equipment of the subscriber equipment under the CELL-FACH; Hereinafter to be referred as: enhanced uplink UE) inserts and is triggered by transmitting uplink data.UE initiates random access procedure after triggering the enhanced uplink access, through public enhancing dedicated channel (the common Enhanced Dedicated Channel of base station (Node B) indication UE use; Hereinafter to be referred as: resource number common E-DCH), wherein, UE obtains radio network controller (Radio Network Controller through broadcast channel; Hereinafter to be referred as: RNC) configuration about the relevant information of common E-DCH resource, thereby can obtain the corresponding common E-DCH resource distribution of common E-DCH resource number, and then can obtain up common E-DCH resource.
UE under CELL-FACH receives high speed descending sharing channel (High Speed Downlink Shared Channel; Hereinafter to be referred as: HS-DSCH) after the data carried by data; If the UE of the current CELL-FACH of having enhanced uplink characteristic has inserted and obtained up common E-DCH resource, then can pass through the proprietary physical control channel of HS-DSCH (Dedicated Physical Control Channel for HS-DSCH; HS-DPCCH) channel carries affirmation (Acknowledgement; Hereinafter to be referred as: ACK)/non-affirmation (Non-Acknowledgement; Hereinafter to be referred as: NACK) with channel quality indication (Channel Quality Indicator; Hereinafter to be referred as: CQI), otherwise the transmission of descending HS-DSCH can only be adopted blind re-transmission mode, promptly repeats to send identical data several times.Blind re-transmission mode can reduce the utilance of descending HS-DSCH resource, reduces downlink throughput capacity.When the base station will send data to UE through the HS-DSCH channel, insert and obtain corresponding HS-DPCCH and feed back the utilance that improves the HS-DSCH resource thereby can not control UE.
In order effectively to utilize the descending HS-DSCH resource of CELL-FACH state, improve the downlink throughput capacity of CELL-FACH state, Node B can control UE and carry out the enhanced uplink access, thereby for descending HS-DSCH transmits feedback is provided.But there is the problem of the descending sign indicating number wasting of resources in the scheme that the enhanced uplink of carrying out existing Node B control UE inserts, and compatibility is lower.
