Group Member Management for Content Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In content-oriented networks, when a user equipment changes groups, existing end-to-end connection technologies face difficulties in efficiently routing and sharing content, leading to increased complexity in routing tables and delayed content sharing due to the need for updating routing paths and recognizing content as different when its group changes.
Innovation Solution
A method where user equipment transmits group change information to previous and new group member management devices, updating member management tables to ensure content requests are routed efficiently through the correct group, even after group changes, reducing network hops and improving sharing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If end-to-end connection technology based on IP is used for content sharing, then content can be shared between devices, but routing complexity increases and content sharing efficiency decreases when user equipment changes groups
Solution Approach 1:
The patent introduces a group member management device as an intermediary between user equipment and the network. This mediator manages group membership information and routing tables, allowing user equipment to share content efficiently without directly handling complex routing updates when groups change. The intermediary absorbs the complexity of tracking group changes and updating routing information.
2Reliability
If routing paths are updated when user equipment changes groups, then content can be routed correctly, but network hops increase and transmission delay increases
Solution Approach 1:
The group member management device performs preliminary actions by proactively updating routing tables and notifying relevant devices before content sharing operations begin. When user equipment joins or leaves a group, the management device pre-computes and distributes updated routing information, so that when content needs to be shared, the correct routing paths are already in place without causing transmission delays.
3Adaptability or versatility
If group change information is propagated to all relevant devices, then content sharing maintains seamless operation across groups, but network overhead increases
Solution Approach 1:
The patent applies local quality by having the group member management device propagate group change information selectively to only those devices that need it, rather than broadcasting to all network devices. The management device identifies and notifies specifically the content requesting device and other relevant peer devices, reducing unnecessary network traffic while maintaining content sharing continuity.

AI summary
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.
