Relay Node Migration Data Loss Prevention in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, relay node migration leads to user data loss and repeated transmission, reducing network efficiency due to interrupted communication between the source and target donor nodes during the migration process.
Innovation Solution
A communication method and apparatus that involve configuring transmission and storage of user data packets through message exchanges between nodes to prevent data loss and retransmission by informing nodes about data packet delivery status, caching, and updating transmission addresses during relay node migration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If relay node migration is performed to improve network flexibility and coverage, then network adaptability is improved, but user data loss and repeated transmission occur reducing reliability
Solution Approach 1:
The source donor node stores user data packets in advance before the relay node migration occurs. This preliminary storage action ensures that data is available for transmission to the target donor node after migration, preventing data loss while maintaining network flexibility
Solution Approach 2:
The source donor node acts as an intermediary by temporarily storing user data packets during the migration process. This intermediary storage function bridges the gap between source and target donor nodes, ensuring continuous data availability and preventing transmission interruptions
2Area of stationary object
If relay node migration is performed to expand network coverage, then area of coverage is increased, but communication interruption occurs reducing productivity
Solution Approach 1:
User data packets are stored in advance at the source donor node before migration. This preliminary preparation ensures that data transmission can continue uninterrupted after the relay node moves to expand coverage, maintaining productivity while extending network area
Solution Approach 2:
The storage and transmission mechanism ensures continuous data flow during relay node migration. By maintaining data availability at the source donor node and enabling seamless transfer to the target donor node, the useful action of data transmission continues without interruption despite the relay node's movement
