Description
Technical field
The present invention relates to communication technical field, particularly relate to the method and apparatus that the buffer queue output speed is measured, and the method and apparatus of Iub allocated bandwidth.
Background technology
Wideband Code Division Multiple Access (WCDMA) (the WCDMA of communication network, Wideband Code Division MultipleAccess) the R5 version (R5 of system, Release 5) in high-speed downlink packet insert (HSDPA, High Speed Downlink Packet Access) technology has realized grouped data sharing on channel code and transmitting power, this mainly is because introduced Adaptive Modulation and Coding (AMC, Adaptive Modulationand Coding), mix (HARQ, Hybrid Automatic Repeat ReQuest) and the fast dispatch technology of retransmitting automatically.Wherein, the realization of fast dispatch technology is to be positioned at radio network controller (RNC, RadioNetwork Controller) Media Access Controlled (MAC, Medium Access Control) layer branch splits out a MAC-hs entity and puts into NodeB, to satisfy the quick resource allocation between a plurality of users.After the MAC layer is split, MAC-d protocol Data Unit (the PDU that generates among the RNC, Protocol DataUnit) utilizes high-speed downlink shared channel (HS-DSCH, high speed Downlink SharedChannel) be sent to MAC-hs among the NodeB by the Iub interface between NodeB and the RNC, wherein each user's MAC-hs entity includes buffer queue separately.Flow control is exactly the process of distributing the Iub bandwidth for each MAC-HS buffer queue, and under the limited situation of Iub transfer resource, and whether allocated bandwidth is fair and reasonable between the user becomes an important evaluation index.
In the prior art, actual output speed according to buffer queue is distributed the Iub bandwidth, and actual output speed is subjected to the influence of the data volume in the buffer queue, when the data volume in the buffer queue is not enough, therefore actual output speed has influenced the correctness of distributing bandwidth less than the throughput of eating dishes without rice or wine of this formation.
As shown in Figure 1, in the prior art, the buffer storage length thresholding of two buffer queues is set: formation high threshold Thrld_high, formation low threshold Thrld_low, then stagnant regions=Thrld_high-Thrld_low.Bandwidth preassignment principle at each buffer queue is:
Wherein, H represents that the storage data are more in the buffer queue, and L represents that the storage data are less in the buffer queue, and stagnant regions can be expressed as state M, and the storage data are moderate in the expression buffer memory.The actual speed that flows out data can be represented with Vout from buffer queue, and Vout=is actual data volume/measuring period of flowing out in measuring period, and data flow flows to user side for the buffer queue from the MAC-hs entity.Expectation flows into the speed of buffer queue data can be represented with Vin, and data flow is the buffer queue that flows into the MAC-hs entity from RNC.Further determine to be the bandwidth of the Iub of each MAC-HS buffer queue distribution, i.e. preassignment bandwidth by the value of determining Vin.The value of Vin obtains by the product of Vout and allocation proportion factor a, and wherein, the allocation proportion factor a under the different conditions can dispose according to the different queue buffer status, for example a
H=0; a
M=1; a
L=1.2.
1. when current state was H, causing Vout was a bigger numerical value, and this moment Vin be one be proportional to Vout than fractional value, buffer queue preassignment bandwidth=a
H* Vout.
2. when current state was L, causing Vout was a less numerical value, and the Vin of this moment is a bigger numerical that is proportional to Vout, buffer queue preassignment bandwidth=a
L* Vout.
3. when current state is M, buffer queue preassignment bandwidth=a
M* Vout.
Yet, produce in the buffer queue data deficiencies transfer sky after, Vout can not reflect user's actual air-interface scheduling ability.Therefore after sky is transferred in formation the startup stage, as being that benchmark distributes the Iub bandwidth with Vout, can ignore the ability of eating dishes without rice or wine of current reality, and cause that allocated bandwidth is less, increase start-up time; Under multi-user's scene, the user is inserted in the back can only obtain the very little speed of eating dishes without rice or wine, and can not reflect that the back inserts user's actual air-interface scheduling ability this moment equally, finally causes between stable back user the Iub allocated bandwidth unreasonable, speed between the user is unbalanced, influences fairness between the user.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
In embodiments of the present invention, for each buffer queue Queue i increases a correction value dDeltaBitCnt who measures output speed, the system that makes can be according to determining input rate through the output speed of revising, and wherein i represents the numbering of buffer queue.
As shown in Figure 2, be first embodiment of the invention, the schematic flow sheet of buffer queue output speed method of measurement.Measurement period T can be divided into an integer dispatching cycle in the embodiments of the invention, preferably be 2ms each dispatching cycle.Be understandable that, use this method to realize measuring the function of buffer queue output speed, can in the dispatching cycle of a measuring period, finish, and comprise measuring period an integer dispatching cycle, promptly may comprise one or more dispatching cycles measuring period.Below to carry out concrete description by situation about forming a plurality of dispatching cycles a measuring period.
Be buffer queue output speed measuring period this measuring period, and this is the measuring intervals of TIME by a fixed length of system's regulation.
Whether step 107 judges measuring period timer MeasurePeriodCnt greater than measurement period T, if greater than, change step 108, otherwise change step 104.
At first calculate actual output speed Vout=dataOutCnt/T, and this actual output speed revised, obtain revised output speed, its formula is: Vout_adjust=(dataOutCnt+dDeltaBitCnt)/T=Vout+dDeltaBitCnt/T.
In the embodiment of the invention, also can before finishing current measuring period, calculate above-mentioned revised output speed Vout_adjust.
If desired, then enter next measuring period, return step 102, repeat above flow process.
Fig. 3 is the step 105 of first embodiment of the invention, and the concrete steps flow process of calcuating correction value dDeltaBitCnt and actual output data quantity dataOutCnt as shown in Figure 3.
This priority can be according to time sequencing, and for example the user of first access network has higher priority than the user of back access; Also can according to how many priority of disposing order of data in the buffer queue, the buffer queue that the data of for example depositing are few has higher priority; Or other standard is determined the height of the priority of buffer queue.
Be without loss of generality, suppose, form " prioritization formation " according to priority order arrangement from high to low buffer queue.
The alternative dispensing means of the embodiment of the invention is, if the current dispatching cycle end also has the not buffer queue of calcuating correction value, can calculate its corresponding correction value in regular turn to remaining buffer queue in next dispatching cycle.
If in dispatching cycle, to the current user's who is handling buffer queue, do not have the flow process of completing steps 202 to step 208 at 2ms, then correction value is not revised.Formation to be checked is not empty, and available sign indicating number surplus resources, power surplus resources do not exhaust, but finish dispatching cycle, then revises correction value and enters next dispatching cycle.
Above-mentioned steps is to finish in the dispatching cycle of 2ms, when 2ms finishes dispatching cycle, enters the dispatching cycle of next 2ms.
Use method embodiment of the present invention, make output speed can reflect the actual schedule ability of buffer queue.Avoid producing in the buffer queue data deficiencies transfer sky after, the actual output speed of buffer queue can not reflect its actual dispatching, thereby may ignore the situation of the ability of eating dishes without rice or wine of current reality.
Use the above method of measuring buffer queue output quantity, can be used for reasonable distribution Iub bandwidth.That is, calculate revised input rate Vin_adjust, adjust the distribution of Iub bandwidth again according to Vin_adjust according to this output speed.The relation of Vin_adjust and Vout_adjust can be linear or nonlinear, and the embodiment of the invention adopts linear relationship, because linear relationship is directly perceived, can be reacted directly into the variation of Vout_adjust on the Vin_adjust, and amount of calculation is little.In addition, the corresponding relation of Vin_adjust and Iub bandwidth is a linear relationship or nonlinear, and present embodiment adopts linear relationship.
The assigning process of Iub bandwidth might not be relevant with the process of the revised output speed of calculating buffer queue.Such as, can when finish a measuring period, distribute the Iub bandwidth, the moment that begins preceding or next measuring period that also can close to an end in the time of current measuring period finishes.
To the distribution of Iub bandwidth, also can directly calculate by Vout_adjust.According to formula: buffer queue preassignment Iub bandwidth=a * Vout_adjust comes for the user distributes the Iub bandwidth, and wherein a is a scale factor.Preferable scheme is:
1. when current threshold conditon was H, causing Vout_adjust was a bigger numerical value, therefore, and buffer queue preassignment bandwidth=a
H* Vout_adjust.
2. when current threshold conditon was L, causing Vout_adjust was a less numerical value, therefore, and buffer queue preassignment bandwidth=a
L* Vout_adjust.
3. when current threshold conditon is M, buffer queue preassignment bandwidth=a
M* Vout_adjust.
Wherein, the allocation proportion factor a under the different conditions can dispose according to the different queue buffer status, and for example scale factor a can value a
H=0; a
M=1; a
L=1.2.
Calculate revised output speed Vout_adjust according to the method in the embodiment of the invention, and then reasonable distribution Iub bandwidth.
Equally, be understandable that, can be regardless of measuring period or littler dispatching cycle, and the method for directly using present embodiment to provide obtains correction value, and calculate revised output speed, distribute bandwidth at last.
Under the prerequisite of Iub limited bandwidth system, the user that the back is inserted is when access network just, data volume is few in this user's the buffer queue, therefore its actual output speed Vout is little, cause the Vin_adjust numerical value that calculates also less, make the back insert the user and can not obtain enough and rational Iub bandwidth; If system is current available sign indicating number surplus resources and power surplus resources are arranged still, this user's buffer queue satisfies QueueLen＜TBS easily so, obtains delt=TBS-QueueLen; Numerical computations according to this delt goes out correction value dDeltaBitCnt, and its computing formula is: dDeltaBitCnt i+=delt; Wherein QueueLen represents is the length of the data deposited in the buffer queue.Like this, when 2ms each time finishes dispatching cycle, the dDeltaBitCnt of this buffer queue can increase, when finish each measuring period, corresponding relation according to dDeltaBitCnt and Vin_adjust and Iub bandwidth calculates the Iub bandwidth that this user should obtain, the Iub bandwidth that this user obtains can increase, and has accelerated this user's transmission rate.
According to the actual throughput ability of eating dishes without rice or wine of measuring buffer queue, the output speed Vout_adjust that is revised buffer queue distributes the Iub bandwidth, produce under the scene of transferring sky in the buffer queue data deficiencies, can reflect the actual schedule ability with revised output speed, avoid allocated bandwidth too small, shortened start-up time; Under the scene of multi-user's access, Iub bandwidth resources deficiency, pass through said method, the user of access network is along with the increase of time has obtained bigger Iub bandwidth after making, can reach desired value rapidly in the time of after initial the access, relatively lacking, then the user who has seized a large amount of Iub bandwidth before this discharges the Iub bandwidth that accounts within a short period of time more, reaches the effect of speed equilibrium between reasonable distribution Iub bandwidth, stable back user.
