Embodiment 1

[0053] Embodiment 1 of the present invention provides a TCP delay processing method, where the execution subject of the method is a terminal device. like figure 1 As shown, the method includes:

[0054] S101, the terminal receives the TCP data packet sent by the base station;

[0055] S102, the terminal parses the TCP message and the TCP ACK information in the TCP data packet;

[0056] S103, the terminal calculates the TCP RTT delay according to the TCP message and the TCP ACK information;

[0057] S104. The terminal sends the TCP RTT delay to the base station according to a preset rule.

[0058] The TCP delay processing method provided by the embodiment of the present invention calculates the TCP RTT delay by using the TCP message and TCP ACK information parsed by the terminal, and reports it to the base station. After the base station parses the TCP RTT delay, it filters the TCP RTT delay according to the TCP RTT delay, and authorizes the terminal according to the TCP RTT ...

Embodiment 2

[0060] The second embodiment of the present invention provides a TCP delay processing method, such as figure 2 As shown, the method includes:

[0061] S201, the terminal receives the TCP data packet sent by the base station;

[0062] Specifically, in this step, the terminal determines whether TCP data is received, and if yes, parses it layer by layer and sends it to the PDCP layer.

[0063] S202, the terminal parses the TCP message and the TCP ACK information in the TCP data packet;

[0064] This step includes:

[0065] The sequence number S1 and the confirmation number Q1 of the TCP message are parsed, and the arrival time T1 of the TCP message is recorded. For example according to image 3 The protocol bits in the shown IP header are parsed. When the corresponding value is 6, it is a TCP packet at this time, and the sequence number S1 and the confirmation number Q1 of the TCP packet are parsed.

[0066] The acknowledgment number Q2 of the TCP ACK information is parsed,...

Embodiment 3

[0108] The third embodiment of the present invention provides a base station 8, such as Figure 9 As shown, the base station 8 shown includes:

[0109] The second receiving module 81 is used for receiving the TCP data packet reported by the terminal;

[0110] The second parsing module 82 is configured to parse the TCP RTT delay in the TCP data packet according to the preset rules with the terminal;

[0111] The authorization module 83 is configured to obtain the TCP RTT filter value according to the TCP RTT delay, and perform delay authorization on the terminal according to the TCP RTT filter value and the TCP RTT instantaneous value within a preset time.

[0112] The second parsing module 82 is specifically configured to read the value of the reserved bits when the reserved bits of the PDCP data PDU are not all 0 to obtain the TCP RTT delay.

[0113] The authorization module 83 includes:

[0114] a first authorization module, configured to perform a delay authorization on ...

Abstract

The present invention provides a TCP delay processing method, device and system, which belong to the field of communication technology. The method includes: receiving a TCP data packet sent by a base station; analyzing the TCP message and TCP ACK information in the TCP data packet; according to The TCP message and the TCP ACK information calculate the TCP RTT delay; and send the TCP RTT delay to the base station according to preset rules. The TCP delay processing method, device and system provided by the present invention can effectively deal with the situation that the TCP RTT delay changes due to the change of the feedback mode, and shorten the delay of the TCP RTT on the LTE air interface scheduling, so that the LTE network is allocated to the terminal. The scheduling resources are more purposeful and targeted, and it also makes the delay for terminals to obtain data lower.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, device and system for processing TCP delay. Background technique [0002] Currently, when a user uses an LTE (Long Term Evolution, Long Term Evolution) terminal to perform operations such as opening a webpage, it often involves TCP (Transfer Control Protocol, Transmission Control Protocol) data transmission based on an LTE network. [0003] TCP (Transmission Control Protocol) is a connection-oriented protocol that provides reliable data transmission between different host processes. In applications that need to provide reliable data transmission, TCP is the preferred or even the only network protocol. There are two ways for TCP to send TCP ACK (Acknowledgement): fast acknowledgment and delayed acknowledgment. [0004] In the fast acknowledgment mode, after the local end receives the data packet, it will immediately send a TCP ACK to the opposite ...
