Abstract

Embodiments of the present invention provide a device-to-device communication method, a module, and a terminal device. The communication module is set in the first terminal device, including: a routing support unit, which is used to generate the identification ID of the D2D communication module, discover the neighbor D2D communication module, and maintain the routing information between the D2D communication module and the neighbor D2D communication module, and the neighbor D2D communication module The communication module is set in the second terminal device; the point-to-point communication unit is used to communicate with the neighboring D2D communication module according to the ID of the D2D communication module and the routing information maintained by the routing support unit. Adopting the technical solution of the present invention can solve the problem of realizing D2D communication between terminal devices.

Description

technical field [0001] The present invention relates to communication technology, in particular to a device-to-device communication method, module and terminal device. Background technique [0002] In traditional cellular communication, there are only two communication modes in the air interface, that is, the uplink transmission from the terminal equipment to the base station and the downlink transmission from the base station to the terminal equipment. With the development of terminal devices, the terminal devices gradually have the ability to communicate with each other. For example, the terminal devices can perform direct data transmission with other terminal devices using Bluetooth, WiFi, and the like. This method of direct communication between terminal devices is called device-to-device (Device-to-Device, D2D for short) communication. [0003] In fact, the D2D communication between terminal devices can not only be used to share the data generated locally by the termin...
