Abstract

An acknowledgement processing method and a base station are provided in the invention. The invention relates to the field of mobile communications and solves the problem of transmission traffic reduction caused by the misjudgement of packet loss when retransmitting data using TCP. The method comprises: after determining the validity of the received ACK, querying the ACK duplicate times of the ACK, wherein the ACK duplicate times is stored in the ACK control block which matches the ACK; if the ACK duplicate times does not reach to the preset restraint threshold, adding one time to the ACK duplicate times and discarding the ACK. The technical solution provided in the invention is applicable to the network using the hybrid automatic repeat request (HARQ) retransmission mechanism.

Description

Method and

Wood field

This relates to the field of communications, and in particular to (AC) methods and methods. Background

The shadow of each factor in Afghanistan is only guaranteed. Control (T smsso Co o ooco TC ) wood, to the TCP buddy in the same, 8, but in the TCP split length, the result P, will receive the TCP. Not friends, in the TCP distribution, the same is sent to receive the reception of the order. However, the reception of the interface that has been successfully received by Hugh has been received, and if it is not received within a reasonable round-trip RTT, then (missed) will be.

In the use of TCP to complete the teaching, there exists

In ample circumstances, it is still possible that TCP cannot

The reason is due to the near due to bad, received heavy AC, received, and the TCP window is halved and the traffic is reduced. Content

This provides an AC method and solves the problem of using TCP.

Cause The traffic is reduced.

AC method, mixing A4, method includes

The AC received in the 有效 is valid, the AC stored in the AC matching AC control, if the AC is not suppressed, then AC increase AC

, AC matching AC control stored in the AC step, the method includes

If the AC is suppressed, then to the special AC, before the step of AC receiving the AC active, AC matching AC control, the method includes

Set the suppression of the number of ACs.

Before the step of receiving AC AC, AC matching AC control stored AC AC, the method includes

Receive AC, whether to receive AC for the first time

If the AC is not received for the first time, does the AC contain the release,

If the AC does not contain a release, then does the AC contain the teachings?

If AC does not include teaching, then AC's AC matching AC control stores whether or not

If AC's AC matching AC control stores the same, AC is valid.

In the step of receiving the AC, whether the AC is received for the first time, the method includes

If the AC is received for the first time, is there an AC matching AC control and

In the presence of AC-matched AC control, the AC control stores the AC and AC or AC control in the absence of AC matching, AC AC control, and AC control to save AC, which will be AC 0.

, in the steps of whether the AC contains the release, Nearly included

If AC is included, the AC matches the AC control and the AC control is removed.

Whether the steps of each teaching are included in the AC, and the method includes

If AC is included and taught, then the special AC is required.

, whether the AC of the AC matches the AC control stored in the same step, the method includes

If the AC is greater than the AC matching AC control stored, the AC is replaced by the AC 0 stored in the AC control and stored in the AC control.

If the AC is less than the AC matching AC control stored, then the AC

Provided recently, mixing A4 Q , said

Query, which is stored in the AC that is valid, AC-matched AC control

, if it is not suppressed by AC, AC will be increased by AC.

Included in the second AC,

AC matching AC control, delete AC control or,

In the third AC, including and teaching, to the special AC or,

Stored in the AC control of the AC that is greater than the AC match, AC is stored in the AC control, and AC 0 is stored in the AC control.

In the AC of less than AC matching AC control stored, AC

This provides the AC method and, on the premise of the hybrid Q system, when the AC is received, whether the AC is valid first, the result is valid in the received AC, and the AC is controlled in the AC control. Compare, increase the number of AC times when the AC limit is not reached

AC, the loss of the successful mask in the Q, there is The reduction of the AC, the rabbit, solved the flow reduction in ample conditions.

The flow of the AC method provided by Liben

2 provided by the power of

The explanation of the offer provided by the 3rd. The preferred way of this

It’s not good to use TCP.

TCP 1 is lost, then TCP 2 and 3 are received, and the AC of the household 1 is received, and the AC is sent to ,

Lost, 1 , reliable is guaranteed, but the same end receives the same AC (C band equal force 1), halving the window.

It is also possible to mix (A4 Q) heavy, but sheep A4, standing on TCP 2 and 3, A4 Q still does not receive 1 , in physical loss of TCP 1 . However, the first 2 and 3 have been sent to receive, and the first AC is received by the household AC 1 , so 1 halved the window, and the received AQ has received 1 and the received 1 is. The AC of the household may cause TCP performance to step down.

In the solution, the AC provides the AC method, in the AC, AC AC, using the AC method provided by the AC to complete the text, as shown in Figure 1, including

Step 101: In each established TCP connection medium control book, AC AC AC, required in the AC .

In this step, each established TCP connection is controlled by AC, TCP is connected to the P control of the AC control end, and the AC and AC of the TCP connection are stored in the AC control that matches the TCP connection.

Included in AC control

TCP connection P (dw p), ( cpo ), destination P (dw s p), destination spo ) 2, the nearest heavy AC and AC (ie AC) dw aesAck dw AckTme

3. North yFag, indicating whether to control cRcvAc ag, indicating whether any AC is received within the interface, and the release (F) is lost.

Multiple AC control AC.

Step 102, suppression of AC

In this step, the AC is suppressed so that the AC is not sent before the Q is completed.

For example, it will suppress 3 and Q 15 , and the same air port will receive up to 3 (5 ms per frame), and receive the AC with the largest number of households 3, so that there is no AC in the Q system.

Step 103: Is the AC received for the first time?

In this step, when the station receives the AC that is first received by the AC, and contains Y, it indicates that the connection strength of the core is newly established. The TCP connection is received for the first time, the AC, the destination P, and the destination suppression AC. If it is not found, the newly established connection is connected to the new AC control, AC is saved in the AC control, AC 0 is set, and AC is controlled to AC. If found, the most stored in the AC control New AC and AC. Wen Chang.

If the AC is not received for the first time, step 104

Step 104, whether the AC contains

Ben, release

In this step, if F is included in the text, the TCP connection will be removed, the AC will be suppressed, and the heavy AC control of the phase will be released. Wen Chang. If F is not included in the text, then step 105, step 105, AC, and

In this, and each teaches TCP.

In this step, the TCP is included in the text, otherwise it is normal, step 106

Step 106: The AC of the AC matches the AC control to store whether the phase is

In this step, the AC in the AC, the destination P, the destination, the AC control phase, the AC control, and the AC AC-matched AC control store the same.

If the AC is less than the AC matching AC control stored, then the AC

When the AC is equal to the AC matching AC control stored, AC is received, AC is valid, step 107, step 107, AC is suppressed.

Step 108: If the AC is not suppressed, the AC is increased by AC.

In this step, the AC stored in the control will receive the AC. Increase the number of times.

However, compare the suppression of AC to determine whether

AC

In this, Q is matched with the weight of the completion, this can be taught by AC 3 (without the AC in the same solid effect of Q), in AC less than 3 AC

Yes, AC is greater than 3 and can be extra

AC (previous) to make TCP faster and faster.

Yes, every time you need to control the AC, you will receive AC 1 in the control, 0 will be 0, and 0 will release AC control. This prevents F loss, or heavy AC control caused by TCP.

Step 109, if the AC is suppressed, then the required special AC

AC is greater than or equal to 3, indicating that Q fails, and AC is constant.

In the above, the AC with and receives the same, and the AC has a good inhibitory effect. And, because of the weight of Q, it can be in AC.

Unsuppressed AC, I can't feel the loss, therefore, the TCP traffic is not falling, TCP is in Q, and Q also fails, then 5, 6. ..... The household has more 1 heavy AC, so the TCP side is heavy, and the reliability of TCP itself is not.

This is provided in the vicinity of 2, including the query 201, which is required in the received AC, AC-matched AC control, AC, AC, etc.

202, its suppression in the AC, then increase the AC AC Step, 202 near AC suppression, to the required special AC

Step, as shown in 3, including

Threshold 203, its suppression of AC

204, which receives AC, whether it receives AC for the first time

The second 205, which is not receiving the AC for the first time, does the AC contain

The third 206, which is not included in the second AC, includes or teaches in the AC

No. 207, which does not include and teach in the third AC, AC's AC matching AC control stores whether or not

The result analysis 208, which is not included in the AC, teaches whether AC is valid.

Step, 202 near, at the 204th, the AC receives AC control for the first time. If there is AC matching AC control, AC control stores AC and AC, or AC control without AC matching, AC AC Control, save AC in AC control, will AC

0 or,

In the second 205 AC,

AC matching AC control, delete control or,

In the third 206 AC, including and teaching, to the special AC or

AC 0 or stored in the AC control of the 207 AC that is greater than the AC matching AC control stored in the AC, and stored in the AC control At the 207th AC less than the AC matching AC control stored, AC

In the above, the AC method provided by this can be combined. Under the premise of the mixed Q system, whether the AC is valid or not after receiving the AC, the result is valid in the received AC.

AC matching AC control stored in the receiving AC, the suppression comparison, in the AC not inhibited, will AC increase AC, in the same use of Q re-AC, effectively reduce the AC, rabbit

, solves the problem of reduced traffic under ample conditions. It can be done by hardware of the program instruction phase, and the program can be stored in

Can be stored, the program is executing, including the steps of the method or a combination thereof.

In addition, the functional sheep in each of these can be in the form of hardware or software functions. The integration can be sold or used in the form of software functions, and can also be stored in the storage.

The storage mentioned above can be only memory, or etc.

The above is the way of rest, but the warranty is not limited to this. Any wood that is familiar with the wood field can be easily conceived or replaced in the wood garden disclosed in this disclosure, and is covered in this warranty. Therefore, this warranty is guaranteed. The AC method and the provided AC method, under the premise of the hybrid Q system, after receiving the AC, first whether the AC is valid, the result is valid in the received AC, and the AC receiving the AC control is stored in the AC control. Suppression comparison, in The AC does not increase the AC, and the AC is increased by the AC. When the Q is re-AC, the AC and the rabbit are effectively reduced, and the flow is reduced in ample situations.
