UE SCG Failure Location Reporting for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, user equipment (UE) experiences high power consumption when frequently reporting location information during Secondary Cell Group (SCG) failures, as it is required to continuously send location data to the network, even after the failure has occurred.
Innovation Solution
The UE only reports location information after determining an SCG failure has occurred, eliminating the need for frequent reporting and reducing power consumption by not requiring the network to instruct location reporting in measurement configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the network instructs the UE to report location information in measurement report configuration, then the network can know the signal quality at each location, but the UE power consumption increases significantly
Solution Approach 1:
The patent applies periodic action by configuring the UE to report location information only at specific intervals or under specific conditions (such as when leaving a configured area or when SCG failure occurs), rather than continuously reporting. This transforms the continuous reporting mechanism into a periodic or event-triggered reporting mechanism, significantly reducing power consumption while maintaining necessary network awareness of UE location for mobility management and failure analysis.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the network with area information and reporting criteria before the UE actually moves or experiences failure. The network pre-defines the conditions under which location reporting should occur (e.g., leaving a configured area, SCG failure), so that the UE only needs to report when these pre-established conditions are met, avoiding unnecessary continuous reporting and reducing power consumption.
2Measurement precision
If the UE frequently reports location information, then the network has accurate location data, but the UE power consumption increases
Solution Approach 1:
The patent transforms frequent continuous location reporting into periodic or event-triggered reporting by configuring the UE to report location only when specific conditions are met (such as leaving a configured area or experiencing SCG failure). This maintains location accuracy when needed while dramatically reducing the frequency of reporting operations, thereby lowering power consumption without sacrificing measurement precision at critical moments.
Solution Approach 2:
The patent applies partial action by reporting location information only partially (only when necessary) rather than continuously. The network configures specific triggering conditions (area exit, SCG failure) and the UE reports location only when these conditions are met, providing sufficient location accuracy for network purposes while avoiding excessive reporting that would increase power consumption.
3Use of energy by moving object
If the UE reports location information only when SCG failure occurs, then power consumption is reduced, but the network may miss location data for other failure types
Solution Approach 1:
The patent applies universality by designing a reporting mechanism that handles multiple failure types (SCG failure, RLF, handover failure) through a unified approach. The UE is configured to report location information for various failure types including SCG failure, radio link failure, and handover failure, making the reporting system multi-functional and applicable to different failure scenarios without requiring separate reporting mechanisms for each type.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the UE with reporting requirements for multiple failure types before failures occur. The network provides configuration information that specifies which failure types should trigger location reporting (including SCG failure, RLF, handover failure), so that the UE is prepared to report appropriately for any of these failure types, ensuring comprehensive failure location data collection while maintaining energy efficiency.

AI summary
The present disclosure relates to an information reporting method and device, an information configuration method and device, a user equipment, a base station, and a computer readable storage medium. The information reporting method comprises: determining that a secondary cell group (SCG) failure occurs; reporting SCG failure-related information to the base station, the SCG failure related information comprising location information of a user equipment (UE). In some embodiments of the present disclosure, the location information is reported after the SCG failure is determined, and location information does not need to be frequently reported, thereby reducing the power consumption of the UE.
