Description

A kind of flow allocation method and system that inserts based on high speed downlink packet

Technical field

The present invention relates to communication technical field, relate in particular to a kind of flow allocation method and system that inserts based on high speed downlink packet.

Background technology

In communication system, can improve the descending ability of communication system greatly based on the high-speed downlink packet access HSDPA technology (HighSpeed Downlink Packet Access) of sharing code channel, caused widely and paid close attention to.One of key property of Wideband Code Division Multiple Access (WCDMA) WCDMA technology (Wideband Code Division MultipleAccess) R5 and R6 version is exactly to introduce the HSDPA technology.HSDPA has increased MAC-hs Flow Control processing entities newly at media access control MAC (the Mdium Access Control) layer of Node B (Node B) side, three new channels also on original physical channel, have been increased: high speed downlink shared channel HS-DSCH (High Speed Downlink Shared Channel), descending shared control signal channel HS-SCCH (High Speed Shared Control Channel), special physical controlling channel of upward HS-DPCCH (Uplink High Speed Dedicated Physical Control Channel).

The basic ideas of HSDPA technology are to set up the shared transmission channel of a high speed to improve message transmission rate.The introducing of HSDPA technology makes the defeated data of Iub oral instructions between radio network controller (RNC) (Radio NetworkController) and Node B on original dedicated channel data, common channel data basis, has increased the HSDPA data.The Iub bandwidth of the data occupancy of dedicated channel and common signal channel is according to the service conditions fixed allocation of transmitting on its channel, and the transmission channel of HSDPA is owing to be shared channel, a plurality of user data are in same channel, and the size of these packets and speed are constantly to change, and the real-time that logarithm reportedly send is less demanding.

In the WCDMA agreement, between RNC and Node B, defined requests for capacity and capacity allocation process and controlled the transmission of HSDPA data on Iub.Capacity request procedure and capacity allocation process are as shown in Figure 1.Specifically, RNC indicates the storage condition of HSDPA data at RNC by the requests for capacity control frame, and requires Node B to respond the capacity allocation control frame to distribute this HSDPA user's data transmission capacity; Node B is after receiving the requests for capacity control frame that RNC issues, can respond the capacity allocation control frame and give RNC, inform the time that speed that the operable HSDPA data flow of RNC sends and this speed exist, and the content of the RNC capacity allocation control frame that can send according to Node B determines whether carrying out the transmission of HSDPA data and the size of transmission rate.In addition, Node B also can initiatively send the requests for capacity control frame to RNC according to the requirement of oneself.

The data of the dedicated channel of Iub mouth and the data of common signal channel all are to send to Node B by RNC, and the HSDPA data also are to send to Node B by RNC.The capacity allocation control frame of Node B side mainly is that the HSDPA data traffic on the control Iub mouth adapts with the data transmitted traffic of eating dishes without rice or wine, and avoids because of eat dishes without rice or wine congested the metadata cache of Node B side being overflowed.Generally the HSDPA data are carried out flow control, realize that to avoid Iub mouth data congestion to rely on RNC this controls all data that send to NodeB with regard to requiring RNC to concentrate.At present such centralized control entity is an option to RNC in agreement, therefore if the RNC side does not have such centralized control entity, then can't make full use of the Iub bandwidth.

At present, when centralized control entity that RNC does not control the business datum that sends to Node B, each HSDPA user's allocated bandwidth is initiated by Node B, HSDPA total bandwidth thresholding also limits by Node B.The current method of carrying out flow control of having proposed much at Subscriber Queue caching situation and user's ability of eating dishes without rice or wine, but these methods all only exist on the basis of a MAC-hs Flow Control processing entities based on Node B, and Node B comprises a plurality of MAC-hs Flow Control processing entities in the actual conditions.At this situation, the HSDPA of Node B can need be distributed bandwidth between each MAC-hs Flow Control processing entities, to distribute, each MAC-hs Flow Control processing entities will distribute bandwidth to carry out flow control as the upper limit of own available bandwidth.

In the prior art, be that HSDPA can be distributed bandwidth mean allocation between each MAC-hs Flow Control processing entities.

Seeing also Fig. 2, is that HSDPA can distribute bandwidth mean allocation flow chart between each MAC-hs Flow Control processing entities in the prior art, comprises step:

S21) the record high-speed downlink packet access HSDPA can distribute bandwidth and Flow Control processing entities number;

At Node B an assignment of traffic processing unit is set, is used to distribute the Iub bandwidth application of each MAC-hs Flow Control processing entities, require this unit record to have the HSDPA of Node B can distribute bandwidth (to be designated as BW _{Iub_HSDPA}) and the interior MAC-hs Flow Control processing entities number (being designated as N) of NodeB.

S22) HSDPA can be distributed the bandwidth mean allocation give the Flow Control processing entities, obtain apportioning cost;

Give the Iub bandwidth of i MAC-hs Flow Control processing entities according to following formula dispensed:

${\mathrm{BW}}_i=\frac{{\mathrm{BW}}_{\mathrm{Iub}\_\mathrm{HSDPA}}}{N}$

S23) distribute bandwidth according to apportioning cost.

NodeB assignment of traffic processing unit is according to step s22) BW that calculates _iEach MAC-hs Flow Control processing entities is distributed the Iub bandwidth.

But there is following limitation in prior art: in each MAC-hs Flow Control processing entities among the user to the desirability difference of Iub bandwidth, mean allocation can not be in real time distributed bandwidth according to the bandwidth demand of each MAC-hs Flow Control processing entities, the bandwidth that makes some MAC-hs Flow Control processing entities obtain is needed greater than reality, and the bandwidth that other Flow Control processing entities obtain can't satisfy its actual bandwidth demand.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of flow allocation method and system that inserts based on high speed downlink packet, these method and system can realize that high-speed downlink packet access HSDPA can distribute bandwidth to distribute according to need, and makes the utilance of interface bandwidth be improved between each Flow Control processing entities.
