UE Timer Control for Satellite Coverage Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in managing registration updates due to discontinuous satellite signal coverage, leading to increased energy consumption and failure rates in registration updates.
Innovation Solution
A method and apparatus for controlling timers in user equipment (UE) and network elements, where the UE determines satellite signal coverage and decides whether to restart the update timer, thereby reducing unnecessary registration updates and associated overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs periodic registration updates according to the update timer, then the network can maintain access state information, but unnecessary registration updates occur in satellite coverage areas leading to increased signaling overhead and power consumption
Solution Approach 1:
The network device performs preliminary action by determining satellite coverage information for the UE's area before the registration update occurs. When satellite coverage is detected, the network proactively sends indication information to the UE to suspend timer operation, preventing unnecessary registration updates and reducing power consumption before the contradiction manifests.
Solution Approach 2:
The system implements feedback through the network device continuously monitoring satellite coverage information and sending indication information to the UE based on real-time coverage status. This feedback mechanism allows the UE to adjust its timer operation dynamically, suspending updates in satellite coverage areas and resuming when coverage is lost, thereby optimizing power consumption while maintaining registration reliability.
2Reliability
If the UE initiates registration update requests when the update timer times out, then the network maintains access state information, but signaling overhead increases due to redundant updates in satellite coverage areas
Solution Approach 1:
The network device performs preliminary determination of satellite coverage information before the UE initiates registration updates. By proactively identifying satellite coverage areas and sending indication information to the UE, the system prevents redundant registration update requests from being generated, thereby reducing signaling overhead while maintaining necessary update reliability in non-satellite areas.
Solution Approach 2:
The network device provides feedback to the UE about satellite coverage status, enabling the UE to intelligently determine whether to initiate registration updates. This feedback mechanism reduces signaling overhead by preventing redundant updates in satellite coverage areas while ensuring updates occur appropriately when satellite coverage is unavailable, maintaining registration reliability.
3Adaptability or versatility
If the update timer is continuously operated without considering satellite coverage, then simple timer management is maintained, but the system cannot adapt to discontinuous satellite signal coverage
Solution Approach 1:
The UE performs self-service by autonomously determining satellite coverage information for its area and independently controlling its update timer operation based on this information. When satellite coverage is detected, the UE suspends timer operation; when coverage is lost, the UE resumes normal timer operation. This self-service approach enables adaptability to satellite coverage conditions without requiring complex centralized control mechanisms.
Solution Approach 2:
The network device performs preliminary action by determining satellite coverage information and sending indication information to the UE before the UE needs to make timer control decisions. This preliminary provision of coverage information simplifies the UE's task, allowing it to adapt to satellite coverage conditions using straightforward timer suspension/resumption logic rather than complex real-time coverage analysis.

AI summary
A method, apparatus and computer readable storage medium for controlling a timer that is used in a wireless communication system. The timer is controlled by: determining, according to satellite coverage information, a satellite signal coverage result of an area where the UE is located in response to determining that an update timer times out; and determining, according to the satellite signal coverage result of the area where the UE is located, whether to restart the update timer.
