Problems solved by technology

Nevertheless, D2D communication today still has the problem of having to perform many complex processes: a device supporting a D2D communication module discovers other nearby devices, sends an inquiry about desired content to all discovered devices, receives a response, identifies other devices for the content, resend the request for the content to the identified device and receive the content

Abstract

The present invention relates to a device-to-device (D2D) content providing method, and to a method of enabling D2D content transmission through a link with a communication control server for supporting D2D content transmission. To this end, the method for providing D2D content according to an embodiment of the present invention may include the following steps: the terminal generates a list of nearby devices by searching for at least one nearby device that can be connected; the terminal sends the list of nearby terminals and the A D2D communication request for content, the request including information about available communication interfaces; receiving by the terminal from the communication control server information about one or more content providing terminals capable of providing information based on a list of neighboring terminals content selected based on information about a communication interface among adjacent terminals included in the terminal; the terminal makes a request to the content providing terminal and receives the content.

Description

Background technique [0001] The details disclosed herein merely provide background information about the implementations and may not be admitted as prior art. [0002] With the development of communication devices and systems, users need services that enable users to easily obtain or share desired information at any time. With the recent advent of smartphones and tablet PCs, an environment for obtaining and sharing various types of information through a communication system has been constructed. However, the communication system has a problem of being unable to effectively provide real-time information due to system complexity or time delay. [0003] Therefore, a device-to-device (D2D) communication technology that performs direct communication between devices is attracting attention. [0004] D2D communication refers to a communication technology capable of establishing a direct communication link between devices and transmitting data without using infrastructure such as a ...
