Network-Side Resource Release for 5G Handover Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, handover latency is a challenge due to inefficient resource utilization during terminal handovers between networks, leading to unnecessary resource occupation and increased signaling overhead.
Innovation Solution
A resource processing method where a network-side device obtains association information of candidate networks and releases handover preparation resources when certain conditions are met, such as lower measurement results or unfriendly network configurations, to optimize resource allocation and prevent continuous occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If handover preparation resources are allocated for multiple candidate networks, then handover reliability is improved, but resource utilization efficiency deteriorates due to continuous occupation
Solution Approach 1:
The network side device performs preliminary allocation of handover preparation resources to multiple candidate networks before the terminal actually hands over. This allows the terminal to quickly select from pre-prepared resources, improving handover reliability while the resources are released after use to maintain efficiency
Solution Approach 2:
Handover preparation resources are allocated temporarily to candidate networks and then released (discarded) once the handover is complete or when the candidate is no longer valid. This recovering mechanism ensures resources don't occupy indefinitely, resolving the contradiction between reliability and utilization efficiency
2Reliability
If measurement and evaluation of multiple candidate networks is performed, then handover reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts and processes measurement results of candidate networks locally at the network side device. By taking out the essential measurement data and evaluating it without requiring extensive signaling exchanges, the system maintains reliable handover selection while reducing signaling overhead
Solution Approach 2:
The network side device autonomously evaluates measurement results and makes handover decisions without requiring multiple rounds of signaling with the terminal. This self-service approach reduces signaling overhead while maintaining reliability through local intelligence
