GNSS Measurement Window Scheduling for Fresh Data Without Idle Reentry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for GNSS information measurement in satellite communication require terminals to enter an idle state when information expires, leading to service delays and significant power consumption due to the need for re-execution of measurement processes.
Innovation Solution
A method and apparatus for measuring GNSS information that involves reporting auxiliary information by terminals to base stations for configuring measurement windows, allowing for proactive GNSS information measurement before expiration, thereby reducing service delays and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal enters an idle state to re-execute GNSS measurement when information expires, then the GNSS information can be updated, but the service delay increases and power consumption increases
Solution Approach 1:
The base station proactively sends measurement configuration information to the terminal before the current GNSS information expires, enabling the terminal to perform measurements in advance and update information while still in connected state, avoiding the time loss of idle state transitions
Solution Approach 2:
The terminal reports auxiliary information (current GNSS info availability, required measurement time) to the base station, which uses this feedback to intelligently determine when and how to send measurement configuration, optimizing the balance between information freshness and service continuity
2Reliability
If the terminal enters an idle state to re-execute GNSS measurement when information expires, then the GNSS information can be updated, but the power consumption increases
Solution Approach 1:
The base station proactively sends measurement configuration information to the terminal before the current GNSS information expires, enabling the terminal to perform measurements in advance and update information while still in connected state, avoiding the excessive power consumption of idle state transitions and access re-execution
Solution Approach 2:
The terminal autonomously determines whether to perform measurement based on receiving measurement configuration information from the base station, eliminating the need to forcibly enter idle state and re-execute access processes, thereby reducing power consumption
3Reliability
If the terminal frequently enters idle state for GNSS measurement, then the GNSS information can be kept updated, but the service continuity is disrupted
Solution Approach 1:
The base station proactively sends measurement configuration information to the terminal before the current GNSS information expires, enabling the terminal to perform measurements in advance and update information while still in connected state, avoiding service interruption
Solution Approach 2:
The measurement configuration is dynamically adjusted based on terminal's current GNSS information status and service requirements, allowing flexible measurement scheduling that adapts to different service scenarios and maintains continuity
