Device to device communication method, a module and a terminal device

Embodiment of the present invention provides a method for a communication apparatus to apparatus, module, and terminal equipment. A communication module is disposed on a first terminal device, comprising: routing support means for identifying the ID generating D2D communication module, the neighbor discovery module D2D communication, and maintain routing information between D2D communication module D2D communication module with a neighbor, the neighbor D2D a communication module provided to a second terminal device; point to point communication unit, in accordance with the routing information for D2D communication module ID and routing support means maintained, in communication with the neighbor D2D communication module. The technical solution of present invention can solve the problem to achieve D2D communication between the terminal device.
