User Equipment Backup Group for Content Object Redundancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices are prone to loss or damage, leading to a high risk of permanent data loss due to their portable and vulnerable nature, as they store valuable content such as photographs, videos, and music.
Innovation Solution
Implementing a backup system where user equipment (UE) can form a backup group with other UEs, allowing content to be automatically copied and stored across multiple devices, with a server facilitating the creation of backup groups and user permission, and utilizing deduplication to manage storage efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is stored only on the mobile communication device itself, then the device can provide full access to all content, but the risk of permanent data loss increases due to device loss or damage
Solution Approach 1:
The system creates duplicate copies of content objects and stores them on multiple user equipment devices within a backup group. When a primary UE loses content, the system retrieves copies from backup UEs, thereby eliminating the risk of permanent data loss while maintaining full content accessibility.
Solution Approach 2:
The backup system divides content storage across multiple independent UE devices rather than relying on a single device. Each UE in the backup group holds a copy of the content, segmenting the storage risk so that loss of one device does not result in complete data loss.
2Reliability
If content is copied to multiple backup devices, then the risk of data loss is reduced, but storage efficiency decreases due to duplicate content across devices
Solution Approach 1:
The system performs deduplication analysis before storing content on backup UEs. By examining content objects in advance and identifying duplicates across the backup group, the system avoids storing redundant copies, thereby maintaining storage efficiency while still providing backup protection.
3Reliability
If a backup group is formed with multiple UEs, then content redundancy is achieved, but system complexity increases due to coordination and permission management
Solution Approach 1:
The backup content application is implemented on each UE device, enabling every device to function both as a primary device needing backup and as a backup device storing content for others. This multi-functionality simplifies the overall system architecture by using the same software solution across all devices regardless of their current role.

AI summary
A user equipment (UE) includes a radio transceiver, a hardware processor and non-transitory storage device. The radio transceiver is to wirelessly couple the UE to a network. The hardware processor couples to the radio transceiver. The non-transitory storage device is coupled to the hardware processor and stores a content object, a group profile data that identifies another UE as a member of a backup group, and a backup content application which, when executed by the hardware processor, causes the hardware processor to access the group profile data to identify another UE and initiate copying of at least a portion of the content object to the identified UE of the backup group.
