The invention discloses a D2D network setup method based on scalable video streaming user quality of experience. D2D communication is organized into a spanning tree for transmitting scalable adaptivevideo streaming. In an initialization phase, a D2D network is organized into the spanning tree with acceptable user quality of experience and fairness. In a management phase, the service continuity isrespectively maintained under the condition that different devices arrive or depart. On the basis of a local search technology, according to the scheme, data structures of disjoint sets and the localsearch technology are combined, the reachable operation time is O [mn alpha (m, n)]. According to the scheme, the capacity of a service network can be improved, the quality of experience, fairness and continuity of the service are ensured, and a great number of users can be supported.
