Method and apparatus for sharing contents using information of group change in content oriented network environment

Abstract

Provided are a method and apparatus for sharing content, using information regarding a group change in a content oriented network environment. In a case where a group to which a target user equipment belongs is changed from a first group to a second group, the target user equipment may transmit, to a first group member management device, the information regarding the group change. The first group member management device may update information about a group to which the target user equipment currently belongs, based on the information regarding the group change. In response to a receiving of a content request from a requesting user equipment, the first group member management device may transfer the content request to the target user equipment.

What is claimed is: 
     
         1 . An apparatus for content sharing in a content oriented network, comprising:
 a processor comprises:   a receiving module configured to receive, from a first device, a sharing request with respect to a target content generated by a second device while the second device belongs to the first group;   a determining module configured to determine whether the second device changed a group from the first group to a second group, based on a member management table; and   a transmitting module configured to transmit the sharing request of the first device to the second device using the member management table.   
     
     
         2 . The apparatus of  claim 1 , wherein the processor further comprising:
 an updating module configured to receive information regarding a group change of the second device from the second device and update the member management table based on the information regarding the group change in response to a group to which the second device belongs changing from a first group to a second group.   
     
     
         3 . The apparatus of  claim 2 , wherein the information regarding the group change comprises at least one of identification information of the second device, information regarding the second group, and information regarding member management equipment included in the second group. 
     
     
         4 . The apparatus of  claim 1 , wherein the transmitting module transmit the sharing request of the first device to the second device through the member management equipment included in the second group. 
     
     
         5 . The apparatus of  claim 1 , wherein the apparatus is included in a server system belonging to the first group. 
     
     
         6 . A target user equipment for content sharing in a content oriented network, comprising:
 a processor comprises:   an information transmitting module configured to transmit, to a first group management device, information regarding a group change in response to a group to which the target user equipment belongs being changed from a first group to a second group;   a receiving module configured to receive, from the first group management device, a sharing request of a request user equipment with respect to a target content, wherein the target content is generated while the target user equipment belongs to the first group; and   a content transmitting module configured to transmit the target content to the request user equipment.   
     
     
         7 . The equipment of  claim 6 , wherein the information regarding the group change comprises at least one of identification information of the target user equipment, information regarding the second group, and information regarding a second group management device. 
     
     
         8 . The equipment of  claim 6 , wherein the receiving module receive the sharing request of the request user equipment from the first group management device through the second group management device. 
     
     
         9 . The equipment of  claim 6 , wherein the information transmitting module transmit, to the first group management device, information regarding the group change, in response to a group to which the target user equipment belongs being changed from the first group, to at least one intermediate group, and subsequently to the second group. 
     
     
         10 . The equipment of  claim 9 , wherein the information transmitting module transmit the information regarding the group change to each intermediate group member management device that corresponds to each intermediate group to which the target user equipment previously belonged while the target user equipment generated a content, among the at least one intermediate group.
