Specifically, the buffer data size and the 2nd BSR of the first BSR buffer data size difference be less than predetermined threshold value feelings
Under condition, the calculated first upstream data amount of this method is actually subjected to the in the same size of the upstream data sent with user terminal, into
And obtain the correspondence that accurate downlink confirms data packet and upstream data amount.
In another alternative embodiment, step 206 is specifically as follows：Second in acquisition data to be transferred buffering area is waiting
Receive upstream data amount；It it was the 4th period according to the sum of the first upstream data amount to be received and the second upstream data amount to be received
Upstream data to be received distributes Internet resources.
Specifically, the upstream data that UE is sent reaches successively, the size of the upstream data transmitted every time can be different.
When the Internet resources deficiency of resource scheduling device distribution, resource scheduling device is recorded by the data to be transferred buffering area configured
The size for not uploading data will not upload a reference factor of the size as lower sub-distribution Internet resources of data.For example, obtaining
After taking the second upstream data amount to be received, resource scheduling device is by the first upstream data amount to be received and the second upper line number to be received
According to the sum of amount as the size in the 4th period upstream data to be received, then distributed for the upstream data to be received of the 4th period
Internet resources.A kind of method of upstream data amount to be received that estimating for the 4th period during TCP connection is thus provided, on
State the size that result of calculation had both considered the upstream data that user terminal will be sent in the 4th period, it is also considered that user terminal
The size for the upstream data not uploaded before the 4th period, resource scheduling device distribute Internet resources according to the result of calculation,
It can preferably meet needed for actual uplink data, and without executing the step of repeatedly reporting SR, uplink scheduling can be improved
Efficiency.
In practical applications, the size for the upstream data to be received that the application uses is actually subjected to send upper with user terminal
There may be certain errors for the size of row data.The application also provides a kind of resource regulating method, can divide Internet resources
It is corrected with error.In another alternative embodiment, on to be received according to the first upstream data amount to be received and second

In another alternative embodiment, after step 206, the above method further includes：Receive the N that user terminal is sent
A Buffer Status Report, N are positive integer；When the buffer data size of N number of Buffer Status Report is zero, stop as user
The upstream data of terminal distributes Internet resources.
Specifically, continuously receiving multiple buffering area state report, and the buffer data size of multiple buffering area state report
When being zero, show that user terminal does not have upstream data to send, resource scheduling device can stop the uplink for user terminal
Data distribution network resource, to avoid the waste of Internet resources.
It should be noted that after step 206, if the buffer data size for receiving a Buffer Status Report is zero,
Resource scheduling device can also stop distributing Internet resources for the upstream data of user terminal.
For ease of understanding, below by resource scheduling device by taking base station as an example, by a concrete application scene to the application
The resource regulating method based on wireless tcp provided describes in detail：
Referring to Fig. 3, the first period send TCP ACK numbers for 10, base station receives within the second period
For row data volume by taking 2000bit as an example, base station determines that the corresponding upstream data amounts of a TCP ACK are：2000/10=200bit.
In the TCP ACK numbers that the third period sends for 5, base station is corresponding with upstream data amount according to TCP ACK
Relationship, it may be determined that be in the upstream data amount to be received of the 4th period：200 × 5=1000bit.Assuming that a TTI transmission
10bit data after base station determines the initial time of the 4th period, 100 TTI are distributed to UE, so that UE uploads 1000bit numbers
According to.
Alternatively, base station determine after the upstream data amount to be received of the 4th period and base station be UE distribute TTI it
Before, if it is 2000bit that UE, which receives BSR and the buffer data size of BSR, base station is more than 1000 comparison result according to 2000, can
To determine the data volume that UE currently to be sent as 2000bit, Internet resources are distributed according to 2000bit.
After the 4th period, if UE does not have, upstream data is to be sent, and it is 0 BSR periodically to report buffer memory.Work as base
When the buffer memory that station receives continuous multiple BSR and multiple BSR is 0, pause distribution Internet resources.
In practical applications, resource scheduling device can select the first time period and the second time period according to actual needs, determine
The correspondence of downlink TCP acknowledgment data packet and upstream data amount.Downlink TCP acknowledgment data are determined according to BSR to a kind of below
The method of packet and the correspondence of upstream data amount is introduced, referring to Fig. 4, the money provided by the present application based on wireless tcp
Another embodiment of source dispatching method includes：
When step 401, the first BSR according to being received from user terminal, the 2nd BSR, upward propagation time delay and downlink are propagated
Prolong and determined for the first period, statistics is sent to the quantity of the first TCP acknowledgment data packet of user terminal as first in the first period
