Problems solved by technology

When the RLC layer of the RNC has a poor ability to send data, the TCP layer of the PDSN cannot perceive it, which increases the amount of cached data on the RNC, causing a large amount of data to be cached on the RNC, resulting in an increase in the RTT measured by the PDSN, and the PDSN is sending TCP data. The time is mainly based on the historical RTT value. When the RTT increases, the TCP data transmission rate will be reduced for a period of time; when the RLC layer of the RNC has a strong transmission capability, the RNC does not get more data and cannot fully utilize the capabilities of the RLC layer. Sending data will lead to a waste of wireless resources

[0049] The first embodiment of the present invention is a data transmission control method of a wireless network, which implements TCP data transmission capability control from a TCP sender to a TCP receiver on an intermediate node. The TCP data transmission capability described in this embodiment is the TCP transmission rate ,Such as image 3 As shown, the method includes the following specific steps:

[0050] Step S101, the intermediate node monitors the TCP sending rate of the TCP sending end in real time;

[0051] Specifically, the intermediate node measures the amount of TCP data sent by the TCP sender in the most recent period, and divides the measured amount of TCP sent data by the most recent period to obtain the TCP sending rate. This step will be completed periodically to obtain in real time TCP send rate.

[0052] The latest period of time can be flexibly set according to actual needs, and the intermediate node measures the amount of TCP data sent by the TCP sende...

[0060] The second embodiment of the present invention is a data transmission control method of a wireless network, which implements data transmission control from a TCP sender to a TCP receiver on an intermediate node. This embodiment is roughly the same as the first embodiment, the difference is that this embodiment The TCP transmission data capacity described in the example is the amount of data sent by TCP, such as Figure 4 As shown, the method includes the following specific steps:

[0061] Step S201, the intermediate node monitors the amount of TCP data sent by the TCP sender in real time;

[0062] Specifically, the intermediate node measures the amount of TCP data sent by the TCP sender within a recent period of time, and this step will be completed periodically to obtain the amount of TCP sent data in real time.

[0063] The latest period of time can be flexibly set according to actual needs, and the intermediate node measures the amount of TCP data sent by the TCP se...

[0069] In the third embodiment of the present invention, a wireless network data transmission control system, such as Figure 5 As shown, the wired network containing the TCP sending end and the wireless network containing the TCP receiving end are connected through an intermediate node, and the TCP transmission data capability control from the TCP sending end to the TCP receiving end is realized on the intermediate node. The TCP transmission described in this embodiment The data capacity is the TCP sending rate, and the system includes the following components:

[0070] The TCP sending end 10 is used to send a TCP data message to the TCP receiving end 20 through the intermediate node 30, and adjusts the TCP transmission data capability of the local end according to the TCP confirmation message returned by the TCP receiving end 20;

[0071] The TCP receiving end 20 is used to return a TCP confirmation message to the TCP sending end 10 through the intermediate node 30 when rece...

Abstract

The invention discloses a method and a system for controlling data transmission of a radio network. The method includes the steps of controlling TCP (transmission control protocol) data transmission on an intermediate node of a transmission network, enabling actual TCP data transmission capability of a TCP transmitter to be close to radio network bandwidth so as to realize good link between an RLC (radio link control) level and a TCP level, and simultaneously avoiding substantial fluctuation of transmission loopback delay. Up-level TCP data transmission can be controlled according to low-level transmission capability of a radio resource, cache data size on an RNC (radio network controller) can be kept within a reasonable range, and waste of bandwidth of a radio network level is avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission control method and system of a wireless network. Background technique [0002] In a wireless network, when users perform high-speed FTP (File Transfer Protocol, file transfer protocol) downloads or HTTP (hypertext transfer protocol, hypertext transfer protocol) downloads, the download rate is often unstable due to uneven distribution of wireless resources. The wireless user data download behavior generally controls data transmission through TCP (Transmission Control Protocol, Transmission Control Protocol) / IP (Internet Protocol, Internet Protocol). TCP is a reliable connection-oriented byte flow control protocol, which is used to control data transmission on the Internet, but it is not suitable for wireless communication networks with large fluctuations in Round Trip Time (RTT), because compared to On a wired network, the performance of TCP dat...
