Problems solved by technology

In this way, it may appear that the UE has not received the data packet, but the Data Sender believes that the UE has received the data packet, which improves the throughput of TCP / IP transmission, but destroys the end-to-end consistency
Once switching across UTRAN, the cached data in Buffer is likely to be lost, and an unrecoverable error will occur

Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] As shown in Figure 2, in the technical solution provided by the embodiment of the present invention, a data transmission processing flow may be as follows:

[0035] Step 21: Obtain the ability information of the receiving end to receive TCP / IP data, adjust the size of the TCP / IP connection window according to the ability information, and notify the sending end of the adjusted TCP / IP connection window size.

[0036] Step 22. Receive and cache the TCP / IP data sent by the sender.

[0037] Step 23. According to the capability information, schedule and send the buffered TCP / IP data to the receiving end.

[0038] In step 21, obtaining the capability information may be to receive the response data returned by the receiving end, the response data contains capability information, and the capability information is obtained by parsing the response data, t...

Abstract

The invention discloses a data transmission method. The method comprises: a receiving end receives the capability information of TCP / IP data. The size of the TCP / IP connection window is adjusted according to the capability information and then the adjusted size of the TCP / IP connection window is noticed to a sending end. The TCP / IP data sent by the sending end is received and is cached. The cached TCP / IP data is dispatched and then sent to the receiving end according to the capability information. Simultaneously, the invention discloses a data transmission device and a data transmission system. Using the invention can improve the transmission throughput of the TCP / IP data, guaranteeing the consistency from end to end and avoiding data loss.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method, device and system. Background technique [0002] With the development of mobile communication technology, the bandwidth of mobile communication system is getting wider and wider, and the types of services it can carry are also becoming more and more extensive. The integration of mobile communication network and Internet has become the development trend of communication technology. The TCP / IP protocol widely used on the Internet is a connection transmission control protocol based on the Internet Protocol (IP). It is designed based on the transmission characteristics of the fixed network system. Applying the TCP / IP protocol to the wireless network will introduce Larger delays lead to degradation of TCP / IP performance. [0003] In order to reduce the delay and improve the data transmission throughput of TCP / IP, the existing technology provi...
