Problems solved by technology
However, the current D2D communication has a problem of having to perform complex multiple processes in which a device supporting a D2D communication module discovers other neighboring devices, sends an inquiry about desired content to all the other devices found, receives a response, and sends the identified Send a request for the content for a specific other device that has the content and then receive the content
[0007] In addition, the current D2D communication technology has another problem of being unable to support a processing method for content requiring authentication (paid content purchased by a device user, content received as a gift from another device user, etc.)

The present invention relates to a method for transmitting content between terminals through a service control device link, and to a method for transmitting content between terminals through a service control device link, capable of supporting content transmission between terminals through a service control device link including a domain name server function. To this end, a method for transmitting content between terminals through a service control device link according to one embodiment of the present invention comprises the steps of: searching for at least one connectible adjacent terminal and creating an adjacent terminal list by a terminal; transmitting, by the terminal, the adjacent terminal list and a domain inquiry message for content to a service control device; receiving, from the service control device by the terminal, information on a content provider terminal capable of providing content among adjacent terminals included in the adjacent terminal list as a response to the domain inquiry message; and making a request for content to the content provider terminal and receiving content by the terminal.
Description
technical field [0001] The present invention relates to a content transmission method between devices through intercommunication with a service control device and a device-to-device content transmission method based on intercommunication with a service control device having a domain name server function. Background technique [0002] The details disclosed herein merely provide background information about the implementations and may not be admitted as prior art. [0003] With the development of communication devices and systems, users need services that allow users to easily obtain or share desired information at any time. With the recent advent of smartphones and tablet PCs, an environment has been constructed that allows users to obtain and share various types of information through communication systems. However, the communication system has a problem of being unable to efficiently provide real-time information due to system complexity or time delay. [0004] Therefore,...
