Terminal Device Connection Release via Timer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cell handover procedures, there is no effective method to timely release connections between terminal devices and source base stations, leading to increased power consumption and detection complexity due to frequent detection of transmission stop signals.
Innovation Solution
A method involving a timer mechanism where a terminal device releases a connection with a source base station after a predetermined timeout, using a cell handover command or RRC signaling to initiate and manage the timer, allowing for controlled and efficient disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal device maintains connections with both source base station and target base station during handover, then data transmission continuity is improved, but connection release complexity and power consumption increase
Solution Approach 1:
The patent applies preliminary action by introducing a timer mechanism that is started in advance during handover preparation. The timer counts down from a predetermined value when the terminal receives the handover command, enabling automatic connection release at a predetermined time without requiring continuous monitoring or complex detection procedures. This resolves the contradiction by simplifying the connection release process while maintaining data transmission continuity through the dual-stack architecture.
2Loss of time
If frequent detection of transmission stop signals is performed, then connection release timing is improved, but power consumption increases
Solution Approach 1:
The patent applies self-service by implementing a timer mechanism that automatically manages connection release without requiring the terminal to actively detect transmission stop signals. The timer self-counts down from a predetermined value and automatically triggers connection release when expired, eliminating the need for continuous active detection and associated power consumption. This resolves the contradiction by providing timely connection release through the timer's automatic expiration rather than through frequent active detection.
3Productivity
If dual stacks of PDCP/RLC/MAC/Low Layer are maintained for Oms handover delay, then handover performance is improved, but connection management complexity increases
Solution Approach 1:
The patent applies preliminary action by establishing dual stacks of PDCP/RLC/MAC/Low Layer in advance during handover preparation, before the actual handover execution. This preliminary setup enables the terminal to maintain both source and target connections simultaneously, achieving Oms handover delay performance. The timer mechanism is also prepared in advance to automatically manage the connection release phase, thereby improving handover performance while controlling connection management complexity through predetermined automation.
