Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in minimizing signaling overhead and user equipment power consumption, particularly in user equipment controlled mobility mode, especially for mobile terminated data transfer, where the network lacks certainty about the user equipment's location during autonomous mobility.
Innovation Solution
The solution involves allowing user equipment to autonomously transition to a mobility mode where it can reselect cells based on signal measurements, with the network maintaining a synchronized timer to initiate optimized paging procedures, reducing signaling overhead and maintaining radio resource control connections during this process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If user equipment controlled mobility mode is implemented, then device autonomy and flexibility are improved, but network certainty about UE location deteriorates
Solution Approach 1:
The network performs preliminary actions by maintaining RRC connection information and initiating optimized paging procedures before the UE actually moves to a new cell. The network proactively prepares for potential mobility events by keeping connection state information available and having paging mechanisms ready, thus maintaining control certainty even during autonomous mobility.
Solution Approach 2:
The system implements feedback mechanisms where the UE provides measurement reports to the network about signal strengths of neighboring cells. This feedback loop allows the network to maintain awareness of UE location and mobility status, resolving the information loss problem while preserving UE-controlled mobility autonomy.
2Stability of the object's composition
If RRC connection is maintained during autonomous mobility, then connection integrity is improved, but signaling overhead increases
Solution Approach 1:
Instead of maintaining the full RRC connection state throughout autonomous mobility, the invention applies partial action by maintaining only essential connection information (RRC connection state) without full active communication. This reduces signaling overhead while preserving enough connection integrity to enable fast reactivation when data transfer is needed.
Solution Approach 2:
The network performs preliminary preparation by maintaining RRC connection information in advance during autonomous mobility. This allows the connection to be quickly reactivated without establishing it from scratch, reducing the need for extensive signaling during actual data transfer resumption.
3Use of energy by moving object
If optimized paging procedures are implemented, then power consumption is reduced, but reactivation speed may deteriorate
Solution Approach 1:
The network performs preliminary actions by maintaining RRC connection information and preparing optimized paging procedures in advance. When data transfer needs to be reactivated, the UE can quickly resume communication using the pre-maintained connection state, achieving both low power consumption during idle mobility and fast reactivation when needed.
Solution Approach 2:
The system dynamically adjusts between different operational states - during autonomous mobility, the UE operates in a low-power state with minimal signaling, but can rapidly transition back to full active communication state when data transfer is needed, thanks to the maintained RRC connection information enabling fast reactivation.
