The invention discloses a network resource allocation method and a network resource allocation device based on a heterogeneous united cache. The method comprises the following steps: in a heterogeneous united network of a mobile edge cache, a base station cache and a D2D cache coexist, all the data is cached through an MEC server at a base station, and some data is cached through user equipment; when a data request of a user is received, according to throughput constraint conditions, interference constraint hierarchy, spectrum factors and power requirements of the heterogeneous united network,power allocation and spectrum allocation are executed for data transmission nodes, and thus, overall target benefit of the heterogeneous united network can be maximized. According to the method and the device provided by the invention, the MEC server is deployed to be more closer to the conventional base station facilities, data resource is coordinated between the users through a D2D cache mode,different modes are select
