Wireless State Transition Bearer Mapping Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In UMTS wireless communication systems, user equipment (UE) often enters idle mode unnecessarily when transitioning from paging states to bidirectional communication states, due to the requirement for radio bearer mapping checks, which disrupts communication and resource usage.
Innovation Solution
The method omits the step of checking for radio bearer mapping information for bidirectional communication states when transitioning from paging states, allowing direct configuration and reducing unnecessary idle mode entries by using pre-configured radio bearers and update messages on fixed mappings like SRB0.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio bearer mapping checks are performed when transitioning from paging state to bidirectional communication state, then communication reliability is ensured, but unnecessary idle mode transitions occur and communication efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by performing radio bearer mapping checks in advance when transitioning from dedicated channel state to paging state. This pre-check ensures that when the UE later transitions back to bidirectional communication state, the mapping information is already available, preventing unnecessary idle mode transitions and maintaining communication efficiency while ensuring reliability
2Manufacturing precision
If radio bearer mapping checks are performed when transitioning from paging state to bidirectional communication state, then configuration validity is verified, but transition time increases and state transition speed deteriorates
Solution Approach 1:
The patent performs radio bearer mapping checks in advance during the transition to paging state, so that when transitioning back to bidirectional communication state, the mapping information is already validated and stored. This eliminates the need for repeated checks during state transitions, maintaining configuration validity while significantly reducing transition time and improving state transition speed
