The invention relates to a double-talk management method based on trunking communication. The double-talk management method comprises the steps of establishing a group calling/broadcasting talk management module and a point-to-point talk management module which are respectively used for managing group calling/broadcasting talk and point-to-point talk; simultaneously connecting the group calling/broadcasting talk management module and the point-to-point talk management module with a wireless access module, wherein the wireless access module is invoked by the group calling/broadcasting talk management module, so as to complete group calling/broadcasting related functions, and the wireless access module is invoked by the point-to-point talk management module, so as to complete point calling related functions; managing group calling/broadcasting by an upper talk module by invoking an interface provided by the group calling/broadcasting talk management module; invoking the point-to-point talk management module to manage the point-to-point talk by the upper talk module by invoking the interface provided by the group calling/broadcasting talk management module. According to the double-talk management method, the technical problem that the group calling/broadcasting talk and the point-to-point talk are simultaneously managed by a terminal through the talk management modules is solved.
