Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 As shown, the present invention is a resource allocation method for D2D communication in a long-term evolution system, including intercommunication devices for direct communication, and users at both ends holding the communication devices. The method includes the following steps:
[0033] (1) The user at one end holding the communication device sends a discovery signal of the mutual communication device to the base station, wherein the discovery signal includes a temporary identifier of the wireless network within the range of the user at the one end;
[0034] (2) The base station performs geographical location detection, wherein the base station obtains the geographical location information of the user at the one end according to the positioning of the base station or GPS or assisted A-GPS, and at the same time feeds back a record related to the user at t...
