Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing positioning configurations during inactive states of user equipment (UE), leading to increased signaling delays and power consumption, especially in scenarios involving UE mobility and handovers.
Innovation Solution
A method and device that allow for the reservation and non-release of positioning-related configurations for UE in inactive states, enabling quicker positioning measurements and reduced signaling exchanges by pre-configuring nodes for positioning tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If positioning configuration is released for UE in inactive state, then system resources are freed, but positioning measurement delays increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring positioning parameters and maintaining configuration information in the inactive state UE context. This allows the UE to perform positioning measurements immediately upon resuming from inactive state without waiting for full configuration re-establishment, thereby reducing positioning measurement delays while efficiently managing system resources through selective retention of configuration data.
2Reliability
If positioning configuration is maintained for UE in inactive state, then positioning measurement continuity is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by selectively maintaining only essential positioning configuration information (such as positioning parameter sets and basic measurement configurations) in the inactive state, while releasing detailed and non-essential configuration parameters. This selective retention approach ensures positioning measurement continuity for critical functions while minimizing the power consumption associated with maintaining full configuration data in inactive state UEs.
3Measurement precision
If positioning configuration is re-configured upon UE state transition, then positioning accuracy is ensured, but signaling delays increase
Solution Approach 1:

Data Source
AI summary
A positioning configuration method in a wireless communication system and an electronic device are disclosed. The method performed by a first node includes: identifying that a user equipment (UE) enters into an inactive state, and transmitting, to a second node, a message including information associated with a reservation of a positioning related configuration, wherein the positioning related configuration is not released for the UE in the inactive state based on the message.
