The invention discloses a method for link self-adaption of video sensing in an HSDPA network. The method comprises the steps of first calculating video transmission utility of a video packet for the video packet of a terminal user; dynamically calculating transmission capability and a corresponding link self-adaption scheme and transmission error probability according to reporting conditions of wireless channel quality signal interference noise ratio (SINR) of the terminal user; finally utilizing a dynamic programming mathematical method to convert a link self-adaption utility maximum restricted problem to a standard mathematical Knapsack problem, and solving a video transmission utility maximum link self-adaption scheme through limited mathematic iteration. According to the method, factors such as video packet transmission utility, user wireless transmission capability and user wireless transmission error probability are considered comprehensively, and simulation experiments show that the wireless transmission capability of video users in an HSDPA system can be effectively improved.
