Satellite Internet Paging Method Using Tracking Area Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The satellite Internet communication system faces challenges in terminal paging and communication reliability due to the lack of a specified tracking area allocation method, which affects mobility management and coverage in high-speed satellite movements.
Innovation Solution
A paging method is introduced that determines the base station for paging based on different tracking area settings, including a single TA, fixed TAs, and non-fixed TAs, using positioning information and TA updates to optimize the paging process and ensure communication reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base station is fixed in a conventional mobile communication system, then the coverage of a cell and the area of a tracking area are fixed, but in the satellite Internet communication system with high-speed moving satellites, the base stations are not stationary and the coverage changes rapidly, making it difficult to allocate tracking areas and perform paging management
Solution Approach 1:
The patent applies the dynamics principle by making the tracking area configuration adaptable to the mobile base station's location. The network dynamically determines whether to use a fixed tracking area or a mobile tracking area based on the base station's current state. When the base station is mobile, the system automatically adjusts the tracking area allocation to follow the base station, enabling effective paging management in high-speed satellite communication scenarios.
2Reliability
If a mobile tracking area is used to follow the base station, then paging management can be performed effectively, but the tracking area changes frequently causing increased signaling overhead and potential paging failures
Solution Approach 1:
The patent applies the preliminary action principle by pre-configuring tracking area information before the base station actually needs to change tracking areas. The network stores historical tracking area data and can predict future tracking area requirements based on the base station's movement pattern. This allows the system to prepare tracking area allocations in advance, reducing the time needed for real-time TA updates and registration when the base station moves between coverage areas.
