Control and User Plane Reconnection for Stalled 5G Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G cellular service network connections can stall due to the failure of either the control plane or user plane, despite the other plane functioning properly, leading to a false indication of a functional connection, which prevents effective network utilization.
Innovation Solution
A method is implemented to check the operational status of both the user plane and control plane, and if one is non-functional, the operational plane is disabled to facilitate a new connection through a different cellular base station or sector, thereby establishing a new network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cellular service network connection maintains both control plane and user plane separately, then connection stability is improved, but connection reliability deteriorates when one plane fails
Solution Approach 1:
The system implements a feedback mechanism that continuously monitors the operational status of both control plane and user plane. When a failure is detected in one plane while the other remains operational, the system triggers an automatic remediation action by disabling the functional plane, thereby forcing reconnection and restoring full functionality to the connection.
2Reliability
If the system detects plane failure and disables the operational plane, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The system performs self-diagnosis and self-healing by automatically detecting plane failures and executing remediation actions without external intervention. The user equipment or base station autonomously monitors connection status, identifies failed planes, and disables operational planes to trigger reconnection, eliminating the need for manual intervention or complex external management systems.
3Ease of operation
If the connection appears functional but one plane is non-operational, then ease of operation is maintained, but productivity deteriorates
Solution Approach 1:
The monitoring mechanism provides feedback about the actual operational status of control and user planes, revealing discrepancies between the apparent connection state and the true functional state. This enables the system to take corrective action before the failure impacts network utilization, maintaining both ease of operation and productivity.
