Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-altitude mobile communication systems experience frequent interface setup, release, and change due to the movement of high-altitude platforms or satellites, leading to deterioration in communication continuity and reliability.
Innovation Solution
An access network apparatus proactively sets up a communication interface with a target network apparatus before transitioning out of the service coverage of a source network apparatus, utilizing context identifiers and parameters to efficiently switch interfaces, thereby maintaining communication continuity and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If high-altitude platforms or satellites move to provide flexible networking and coverage, then adaptability and coverage area are improved, but interface stability and communication continuity deteriorate due to frequent setup, release, and change operations
Solution Approach 1:
The patent applies preliminary action by pre-configuring context parameters and establishing communication interfaces before the high-altitude platform or satellite actually needs to switch. The access network apparatus proactively sets up the interface with the target network apparatus in advance, using stored context parameters to accelerate the process, thereby maintaining communication continuity during movement.
2Reliability
If optical fiber links are used in terrestrial networks to ensure stable topology, then reliability is improved, but adaptability to mobile high-altitude scenarios deteriorates due to the static nature of fiber connections
Solution Approach 1:
The patent applies dynamics by creating a dynamic interface management system that adapts to the moving high-altitude platform. Instead of static fiber connections, the system dynamically establishes, maintains, and switches communication interfaces based on the real-time position and service requirements of the high-altitude platform, enabling both reliability and mobility.
3Area of stationary object
If frequent interface setup and release operations are performed to track moving platforms, then coverage area is improved, but communication continuity deteriorates due to the time required for interface establishment
Solution Approach 1:
The patent applies preliminary action by pre-configuring context parameters and establishing communication interfaces before the high-altitude platform or satellite actually needs to switch. The access network apparatus proactively sets up the interface with the target network apparatus in advance, using stored context parameters to accelerate the process, thereby maintaining communication continuity during movement.

AI summary
This application discloses a communication method, and is applicable to satellite communication or high-altitude platform communication. The method includes: An access network apparatus sends a first request to a target network apparatus; the target network apparatus sends a first response to the access network apparatus after configuring a context parameter of a first communication interface for communication with the access network apparatus; and the access network apparatus sets up the first communication interface with the target network apparatus based on the first response, and switches a corresponding communication interface from a second communication interface with a source network apparatus to the first communication interface.
