Problems solved by technology

Therefore, even if a certain TCP link is abnormally closed, the RAN device still transmits the cached or received TCP data packets in the above-mentioned TCP link, which obviously affects the power, code, interface bandwidth and other resources of the wireless network. would be a waste

Embodiment 1

[0020] In the embodiment of the present invention, after the access network device receives the TCP packet carrying the reset flag in the TCP, the TCP packet is sent after the user equipment or the server detects that the TCP link to which the TCP packet belongs is abnormal.

[0021] The access network device parses the TCP packet to obtain quintuple information carried in the TCP packet. The quintuple information includes: source address, destination address, source port, destination port, and protocol, according to The five-tuple information determines the TCP link to which the TCP packet belongs, and sets the state of the TCP link as disconnected.

[0022] The access network device distinguishes the buffered and subsequently received TCP packets in the disconnected TCP link into TCP signaling packets or TCP data packets, and continues to transmit the TCP signaling packets, The TCP data packet is discarded.

[0023] The embodiments of the present invention will be described...

Embodiment 2

[0036] This embodiment provides a data processing device for a TCP link, which is set in an access network device, and its specific structure is as follows image 3 As shown, the following modules are included:

[0037] The state determining module 31 of TCP link, after receiving the TCP packet that carries reset sign in Transmission Control Protocol TCP, the state of the TCP link that described TCP packet belongs is set as disconnection;

[0038] The TCP data packet discarding module 32 is configured to discard the TCP data packets in the disconnected TCP link obtained by the TCP link state determination module.

[0039]Further, the device may also include:

[0040] The TCP flow record information deletion module 33 is configured to start a timing operation of the timing duration of the timer, and after the timing operation ends, the wireless access network deletes the saved record information of the TCP flow.

[0041] Specifically, the state determination module 31 of the ...

Abstract

The embodiment of the invention provides a data processing method and device of a transmission control protocol (TCP) link. The method mainly comprises the following steps that after a radio access network (RAN) receives a TCP packet which carries a reset sign in the TCP, the state of the TCP link that the TCP packet belongs to is set to be disconnected; and the RAN disposes the acquired TCP data packet in the TCP link of which the state is set to be disconnected. According to the embodiment of the invention, the TCP data packet in the TCP link which is disconnected abnormally can be disposed in time, so that the transmission of useless data in a wireless network is reduced, and the purpose of saving the resources of the wireless network is achieved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a data processing method and device for a TCP (Transmission Control Protocol, Transmission Control Protocol) link. Background technique [0002] At present, there are many types of services in the mobile Internet, and most of the services are transmitted through the bearer of TCP. However, due to the characteristics of TCP itself, unnecessary data transmission will be caused in the network. For RAN (Radio Access Network, wireless access network) equipment, resources such as power, code, and interface bandwidth for transmitting data are in short supply. Therefore, optimization measures are taken for data carried by TCP to reduce unnecessary data transmission to save Wireless resources appear to be necessary. [0003] The establishment principle of the TCP link mainly includes: a TCP flow is determined through the five-tuple information composed of source IP a...
