description Disclosed are a data offloading method and apparatus based on D2D communication. The data offloading method according to the present invention as the data offloading method performed in a first base station of a communication network, includes the steps of: receiving a message requesting a first content from a first terminal connected to the first base station; transmitting a message requesting meta data of the first content based on a routing path indicated by a previously stored finger table; receiving a message including the meta data of the first content from a second base station included in the communication network; and supporting communication to make the second terminal including the first content transmit the first content to the first terminal based on the meta data of the first content. Accordingly, the present invention can smoothly provide a content streaming service to a user. D2D 통신 기반의 데이터 오프로딩 방법 및 장치가 개시된다. 본 발명에 따른 데이터 오프로딩 방법은 통신 네트워크의 제1 기지국에서 수행되는 데이터 오프로딩 방법으로서, 제1 기지국에 접속된 제1 단말로부터 제1 컨텐츠를 요청하는 메시지를 수신하는 단계, 미리 저장된 핑거 테이블이 나타내는 라우팅 경로에 기초하여 제1 컨텐츠의 메타데이터를 요청하는 메시지를 전송하는 단계, 통신 네트워크에 포함된 제2 기지국으로부터 제1 컨텐츠의 메타데이터가 포함된 메시지를 수신하는 단계 및 제1 컨텐츠의 메타데이터를 기반으로 제1 컨텐츠를 보유한 제2 단말이 제1 단말로 제1 컨텐츠를 전송하도록 통신을 지원하는 단계를 포함한다.
