Description
Technical field
The present invention relates to HSDPA multithread technology, refer to especially a kind of Flow Control distribution method and device of HSDPA multithread technology.
Background technology
Along with the fast development of data service, high-speed packet access (HSPA, High-Speed Packet Access) technology is applied more and more at large, and to the future development of multi-antenna multi-carrier-wave.Such as, the R7 version of 3GPP has been introduced multiple-input and multiple-output (MIMO, Multiple-Input Multiple-Out-put) technology, make target network element (may be base station (NodeB) and/or drifting radio network system (DRNS, Drift Radio Network Subsystem)) to send two transmission blocks to subscriber equipment (UE) by double antenna from same community simultaneously; Subsequently, the R8 version of 3GPP has been introduced two carrier wave high speed downlink packet access (DC-HSDPA, Dual Cell-High Speed Downlink Packet Access) technology makes target network element from two frequencies of two neighbor cells, to send HSDPA data to UE simultaneously.The introducing of these two technology, has improved the data throughout of community to a great extent.
When UE is in edge, two co-frequency cells and carry out soft handover or during More Soft Handoff, serving high speed downlink shared channel (HS-DSCH often, High-Speed Downlink Shared Channel) limited ability of eating dishes without rice or wine of community, and non-service HS-DSCH community in Active Set also has available resources, if can also send out data from non-service cell to UE simultaneously, will greatly improve user's impression, thereby also improve the data throughout of community.Therefore, the R11 version of 3GPP enters on the multithread technology of HSDPA.

The Flow Control distributor of 14. 1 kinds of HSDPA multithread technology, is characterized in that, comprising:
Indicating module, for by user cache size (User Buffer Size) cell and the newly-increased cell of HS-DSCH Frame or HS-DSCH capability requests frame, indicates corresponding user cache dimension information to each target network element; Described user cache dimension information is: the ratio of the user cache size that the relatively corresponding HS-DSCH of user cache size priority query that this NodeB uses is total is expected by the user cache size that corresponding HS-DSCH priority query is total and corresponding HS-DSCH priority query.
15. according to the Flow Control distributor of HSDPA multithread technology described in claim 14, it is characterized in that,
Described indicating module, also for indicating the total user cache size of described corresponding HS-DSCH priority query by described User Buffer Size cell; And, by the described corresponding HS-DSCH of described newly-increased cell indication priority query, expect the ratio of the user cache size that the relatively corresponding HS-DSCH of user cache size priority query that this NodeB uses is total.
16. according to the Flow Control distributor of HSDPA multithread technology described in claim 15, it is characterized in that,
Described device also comprises: analysis module, for according to the synthetic load of the total user cache size of corresponding HS-DSCH priority query and each target network element, determine the ratio of the user cache size that the relatively corresponding HS-DSCH of user cache size priority query that described corresponding HS-DSCH priority query corresponding to each target network element expect that this NodeB uses is total, and offer described indicating module; Also for the total user cache size of corresponding HS-DSCH priority query is offered to described indicating module.
