A method for dynamically adjusting network parameters of a mobile terminal browser, the method comprising: setting an upper threshold value and a lower threshold value of a downloading speed for a mobile terminal browser, and further comprising: calculating a current average downloading speed of the mobile terminal browser; comparing the current average downloading speed with the upper threshold value and the lower threshold value of the downloading speed; and resetting network parameters of the mobile terminal browser when the current average downloading speed is less than the lower threshold value of the downloading speed or greater than the upper threshold value of the downloading speed; wherein the network parameters comprise at least one of the following: downloading priority of webpage resources, a downloading timing interval, downloading timeout of each resource, and a number of downloading tasks supported currently, and characterized in that, the step of resetting network parameters of the mobile terminal browser comprises: when the current average downloading speed is less than the lower threshold value of the downloading speed, setting downloading priority of image and/or flash resources in the webpage to be lowest, and setting priority of text and JavaScript resources in the webpage to be highest, and/or prolonging the downloading timing interval, and/or prolonging the resource timeout, and/or reducing the number of the simultaneously downloading tasks supported currently; and when the current average downloading speed is greater than the upper threshold value of the downloading speed, increasing the downloading priority of the image and/or flash resources in the webpage, and/or shortening the downloading timing interval, and/or shortening the timeout, and/or increasing the number of the simultaneously downloading tasks supported currently. calculating a current average downloading speed of the mobile terminal browser; comparing the current average downloading speed with the upper threshold value and the lower threshold value of the downloading speed; and resetting network parameters of the mobile terminal browser when the current average downloading speed is less than the lower threshold value of the downloading speed or greater than the upper threshold value of the downloading speed; wherein the network parameters comprise at least one of the following: downloading priority of webpage resources, a downloading timing interval, downloading timeout of each resource, and a number of downloading tasks supported currently, and characterized in that, the step of resetting network parameters of the mobile terminal browser comprises: when the current average downloading speed is less than the lower threshold value of the downloading speed, setting downloading priority of image and/or flash resources in the webpage to be lowest, and setting priority of text and JavaScript resources in the webpage to be highest, and/or prolonging the downloading timing interval, and/or prolonging the resource timeout, and/or reducing the number of the simultaneously downloading tasks supported currently; and when the current average downloading speed is greater than the upper threshold value of the downloading speed, increasing the downloading priority of the image and/or flash resources in the webpage, and/or shortening the downloading timing interval, and/or shortening the timeout, and/or increasing the number of the simultaneously downloading tasks supported currently.
