METHOD AND DEVICE FOR CONTROLLING DATA TRANSMISSION

摘要

Disclosed are a method and a device for controlling data transmission, so as to improve wireless resource utilization. The method in the embodiment of the present invention includes: obtaining information about a strategy factor which includes at least one of information about sub-district congestion and user information about the user who is using a transport control protocol (TCP) service; adjusting a TCP congestion control parameter according to the information about the strategy factor, if a preset transmission control condition is satisfied; and controlling the data transmission rate of the user using the adjusted TCP congestion control parameter. Further provided is a device for controlling data transmission. The present invention is capable of improving wireless resource utilization effectively.
