Problems solved by technology

When two-way concurrent transmission of TCP data packets, the terminal simultaneously sends uplink data (TCP data packets) and downlink data (TCP response responses) in the uplink. In this asymmetric uplink and downlink, due to the uplink The traffic is low, and the uplink data (TCP data packet) will affect the timely sending of downlink data (TCP response response), resulting in a decrease in downlink data traffic

Embodiment Construction

[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] Such as figure 1 as shown, figure 1 It is a flow chart of the first embodiment of the TCP bidirectional concurrent transmission control method of the present invention. The TCP two-way concurrent transmission control method mentioned in this embodiment includes:

[0043] Step S101, obtaining the uplink rate threshold according to the uplink and downlink configuration information in the network system information;

[0044] In this embodiment, the uplink rate threshold is obtained by using the uplink and downlink configuration information broadcast by the network in the system information, combined with the transmission capability of the terminal. Among them, the uplink and downlink configuration information, that is, the slot ratio information, can be easily obtained by analyzing the network system informatio...

Abstract

The invention discloses a TCP two-way concurrent transmission control method and device. The method comprises: obtaining the current TCP sending rate and the current TCP receiving rate; judging whether the current TCP receiving rate is greater than the current TCP sending rate; when the current TCP receiving rate is greater than the current TCP receiving rate When sending the rate, it is judged whether the current TCP sending rate is greater than the uplink rate threshold; when the current TCP sending rate is greater than the uplink rate threshold, the sending of TCP data packets is suspended, and the TCP response is sent preferentially. The present invention utilizes the uplink and downlink configuration information broadcasted by the network in the system information to obtain threshold data. The threshold data acquisition method is simple, convenient and fast, which is beneficial to improve the work efficiency of the entire transmission regulation, and allocate more network transmission flow resources to TCP downlink data. Ensure the timely sending of TCP downlink data, improve the transmission flow of TCP bidirectional concurrent, and maximize the use of network resources.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a TCP bidirectional concurrent transmission control method and device. Background technique [0002] TCP (Transmission Control Protocol, Transmission Control Protocol) is a transmission-confirmation system. Its transmission principle is that when data is transmitted between two hosts A and B, host B sends one or more The TCP data packet is sent to host A, and then waits for the confirmation of host A; after receiving the TCP data packet, host A sends a TCP response to the received TCP data packet; after receiving the TCP response, host B continues to send subsequent TCP data packets. It can be seen from the transmission principle of TCP that the timely sending of TCP response is the guarantee for improving the traffic of TCP transmission. However, in a wireless network environment, according to service characteristics, the uplink and downlink traffic is asymmetrical, and ...
