Claim:
1. A method for achieving device-to-device D2D communication, comprising: a controlling user side requesting a network side for coordinating current D2D communication resources; the network side determining a new D2D communication resource according to current D2D communication demand information and D2D candidate resource information of a controlled user side; and using the new D2D communication resource to achieve the D2D communication between a controlling user and a controlled user; wherein the following is further comprised before the method: a base station of a cell where the controlling user is located at the controlling user side allocating channel resources occupied by the D2D communication, wherein a channel resource shortage exists; and the channel resource shortage comprises: a mutual interference between other users within the cell where the controlling user is located and the controlling user, and/or expense settlement of the controlling user; the request for coordinating the current D2D communication resources carries demand information for achieving the current D2D communication, comprising: information of the controlled user in the current D2D communication, and traffic and quality of service of the D2D communication; the D2D candidate resource information at least comprises: a candidate resource that is spare and available for D2D multiplexing; said determining the new D2D communication resource comprises: judging whether the D2D candidate resource meets current D2D communication demands, and if the D2D candidate resource meets the current D2D communication demands, determining the D2D candidate resource as the new D2D communication resource.
