To the flow control of Iub mouth, mainly adopt buffer memory balanced flow control (BBFC, Backlog Balancing Flow Control) pattern in the prior art, control the metadata cache amount of service queue by high threshold and low threshold are set for service queue.When the metadata cache amount of service queue exceeded the high threshold of setting, RNC stopped to carry out the transmission of data by the NodeB notice; When the metadata cache amount of service queue is lower than the low threshold of setting, is this service queue distribution Iub port band width again by NodeB, and carries out the data transmission again according to the Iub port band width size notice RNC that is assigned to.Wherein, high threshold being set can avoid occurring owing to service queue overflows the phenomenon that causes loss of data; Low threshold is set controls data in the service queue on low threshold, avoid producing owing to data deficiencies in the service queue causes the situation that does not have data to send.
In actual applications, dissimilar business is different to the flow control demand of Iub mouth, and existing flow control methods, when high threshold that the metadata cache amount is set and low threshold, do not distinguish for type of service, adopt unified high threshold and low threshold to carry out flow control various types of traffic.Because existing flow control methods can't be at the different flow demand for control of business, adaptive high threshold and low threshold to the data buffer memory distinguished setting, therefore also just can't realize Adaptive Control, cause unreasonable to the flow control of Iub mouth easily Iub mouth flow.

Embodiment
The technical solution of the present invention is further elaborated below in conjunction with the drawings and specific embodiments.
In order to satisfy the different flow demand for control of different kinds of business, realization is to the adaptability flow control of business, the invention provides a kind of flow control methods, according to the relevant information in the business contract, high threshold and low threshold to the metadata cache amount of different business carry out adaptive setting, and can also upgrade in time according to the actual transmissions situation of data high threshold and the low threshold to the data buffer memory in data transmission procedure.
Flow control methods provided by the present invention as shown in Figure 1, mainly may further comprise the steps:
When business produces, in RNC, can generate and professional corresponding business contract, comprise in the business contract: guarantee bit rate (GBR, Grant Bit Rate), peak rate (Peak) and the professional maximum data delay time relevant informations such as (Discard Time) that allows.Wherein, GBR is professional desired serviced speed, and professional specified data need transmit according to particular rate among the GBR; Peak is the peak rate of professional predetermined data transmission.
When initially setting up data transmission link, RNC is carried at business contract and sends to NodeB in the request for building link, by GBR, Peak and the Discard Time information in the NodeB extraction business contract, and calculate the high threshold and the low threshold of the metadata cache amount of service queue by following formula
Threshold?High＝GBR×Discard?Time (1)
Threshold?Low＝2×Peak×Delay (2)
In above-mentioned formula (1), (2), Threshold High represents the high threshold of metadata cache amount, and ThresholdLow represents the low threshold of metadata cache amount, and Delay represents the propagation delay time of Iub mouth, and Delay is the known quantity that NodeB can get access to.
High threshold for shown in the above-mentioned formula (1) is provided with according to a kind of limit.Suppose that the data in the service queue are never dispatched by NodeB, the data in the service queue increase always, then in order to prevent that data from losing owing to overtime, need metadata cache amount in the control service queue in set Threshold High.Hence one can see that, if the metadata cache amount in the service queue exceeds the high threshold of setting, some data in the service queue then can occur owing to overtime situation of losing.
Low threshold for shown in the above-mentioned formula (2) is provided with according to another limit.Suppose that NodeB is desirable scheduling to the data dispatch in the service queue, then transfer empty situation in order to prevent service queue, when the metadata cache amount in the requirement service queue reaches low threshold, send the capacity allocation frame to RNC immediately by NodeB, RNC gives a response after receiving the capacity allocation frame immediately; Send the capacity allocation frame to the response that receives from RNC from NodeB, required time delay is 2 * Delay.Send the capacity allocation frame in the process that receives from the response of RNC at NodeB, suppose that RNC sends to NodeB without any data, and NodeB carries out data dispatch according to the speed of Peak, then transfer empty situation, need to guarantee that the data in the service queue are at least 2 * Peak * Delay in order to prevent service queue.
It is to be noted, in actual applications, for dissimilar business, GBR in its business contract, Peak are different with Discard Time information, thereby also are different according to the high threshold of the metadata cache amount of the set corresponding different kinds of business of above-mentioned formula (1), (2) with low threshold.
Issue in the process of data to NodeB at RNC, NodeB monitors the metadata cache amount in the service queue, when the metadata cache amount in service queue exceeds the high threshold of setting, NodeB sends the capacity allocation frame that forbidden data sends to RNC, and the data that stop service queue with notice RNC send; When the metadata cache amount in service queue is lower than the low threshold of setting, NodeB is the data transmission rate that service queue is redistributed Iub port band width and RNC, and notice RNC carries out the transmission of data according to Iub port band width of redistributing and the data transmission rate of RNC.
When the metadata cache amount in the service queue exceeded the high threshold of setting or is lower than the low threshold of setting, NodeB was adaptive according to current transmission status, and according to following formula high threshold and low threshold was upgraded setting:
Threshold?Low
n＝2×Delay×(Peak-Rate) (4)
In above-mentioned formula (3), (4), Threshold High
nHigh threshold after expression is upgraded, ThresholdHigh
N-1High threshold before expression is upgraded, Threshold Low
nLow threshold after expression is upgraded, Rate are represented the RNC data transmission rate redistributed, and RNC_BO represents the current data growth rate of RNC side in the service queue, and NB_BO represents the current data growth rate of NodeB side in the service queue, n 〉=1, and n is an integer.
RNC_BO in the formula (3) is carried in the data of transmission by RNC to send to NodeB, and NB_BO is monitored the transmission status of service queue by NodeB and obtains.Analyze as can be known by formula (3), if the relative NB_BO of RNC_BO is bigger, show that then the Data Growth of RNC side in the service queue is very fast, the high threshold Threshold High after the renewal
nCompare the high threshold Threshold High before upgrading
N-1Increase, to guarantee the quick transmission of RNC side data; RNC_BO is bigger if NB_BO is relative, shows that then the Data Growth of NodeB side in the service queue is very fast, the high threshold Threshold High after the renewal
nCompare the high threshold Threshold High before upgrading
N-1Decrease,, guarantee that the data of NodeB side are not overflowed with the data transmission of restriction RNC.
For the renewal low threshold shown in the above-mentioned formula (4), be to be provided with: suppose that NodeB dispatches the data in the service queue according to peak rate Peak according to the following limit, and RNC sends data according to the speed Rate that NodeB redistributes to NodeB, in order to prevent that data in the service queue from being transferred emptyly by NodeB, the data in the service queue should not be less than 2 * Delay * (Peak-Rate).
It is to be noted, the situation that exceeds high threshold for the metadata cache amount in the service queue, NodeB does not need to redistribute the data transmission rate of Iub port band width and RNC, therefore, the low threshold after obtaining in this case upgrading with upgrade before low threshold identical.
After the high threshold of metadata cache amount and low threshold upgrade in to service queue, NodeB controls the flow of service queue according to the high threshold and the low threshold of the metadata cache amount after upgrading, if still occur the situation that data in the service queue are higher than high threshold or are lower than low threshold in the follow-up data transmission procedure, then the NodeB adaptability of proceeding high threshold and low threshold according to above-mentioned formula (3), (4) is upgraded.

Step 202, NodeB is provided with the high threshold and the low threshold of metadata cache amount according to the business contract in the request for building link.
NodeB extracts relevant informations such as GBR, Peak and Discard Time from the business contract of request for building link, the relevant information according to extracting is provided with the high threshold and the low threshold of data buffer memory respectively according to above-mentioned formula (1), (2).
Step 203, the link establishment confirmation that NodeB will carry set high threshold and low threshold returns to RNC.
Step 204, when business datum arrived RNC, RNC sent capacity request frame to NodeB, informs that the NodeB corresponding service need send data, comprises the metadata cache amount that RNC is current in this capacity request frame.
Step 205, NodeB receives the capacity request frame from RNC, and the Iub port band width that carries out service queue according to the current metadata cache amount of RNC distributes, and the allocated bandwidth result is carried in the capacity allocation frame returns to RNC.
Step 206, RNC receives the capacity allocation frame from NodeB, and issues data according to the allocated bandwidth result to NodeB.RNC carries RNC_BO in the data that NodeB issues, to inform the Data Growth situation of NodeB RNC side in service queue.
Step 207, in the data transmission procedure, NodeB monitors the metadata cache amount in the service queue, when the data of NodeB side exceed the high threshold that is provided with in the step 202, NodeB sends the capacity allocation frame that forbidden data sends to RNC, the data that stop service queue with notice RNC send, and carry out the adaptability renewal of high threshold and low threshold according to above-mentioned formula (3), (4).
Step 208, when the data of NodeB side are lower than the low threshold that is provided with in the step 202, NodeB is the data transmission rate that service queue is redistributed Iub port band width and RNC, notice RNC carries out the transmission of data according to Iub port band width of redistributing and the data transmission rate of RNC, and carries out the adaptability renewal of high threshold and low threshold according to above-mentioned formula (3), (4).
