D2, if more than preset threshold, then the downloading translocation factor of the user terminal is added 1；
If d3, being less than preset threshold, window field right shift " downloading translocation factor " size will be received in TCP packet.
Before executing above-mentioned steps, previous step is first carried out in advance:
Whether s1, the upload for judging the user terminal or downloading translocation factor have initialized；
If s2, having initialized, the corresponding steps that adjustment transport layer receives window are executed；
If s3, no initializtion, the upload of the user terminal or downloading translocation factor are first initialized as 0, then execute
Adjust the corresponding steps that transport layer receives window.
Wherein, the preset threshold is 500ms.
The process that window is received by adjustment transport layer described in the step, realizes and controls the transmission rate of user terminal,
The terminal of containment high-speed plays the role of balanced base station overall rate so as to ensure the experience of base station other users.
