Multiple HAP Base Station Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High Altitude Platforms (HAPs) base stations experience significant path loss and data loss due to large distances from user equipment, leading to disconnection issues, and the movement of these stations further exacerbates connectivity problems.
Innovation Solution
User equipment with processing circuitry and transceivers scans for multiple communication hubs, determines connection parameters based on signal strength, and dynamically adjusts connections to maintain optimal network connectivity by establishing and updating connections with the best available hubs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single HAPs base station is used for communication, then the device complexity is low, but the reliability of connection deteriorates due to path loss and movement
Solution Approach 1:
The patent combines multiple base station connections (first base station and second base station) into a unified communication system. The user equipment simultaneously maintains connections with multiple HAPs base stations, merging their resources to improve overall connection reliability and mitigate path loss effects through diversity.
Solution Approach 2:
The system implements feedback mechanisms where the user equipment monitors signal conditions and base station movements, then dynamically adjusts connection parameters. The network device provides feedback about base station locations and connection status, enabling adaptive connection management that maintains reliability while controlling complexity.
2Area of stationary object
If the user equipment connects to a distant HAPs base station, then the coverage area is extended, but the signal strength deteriorates due to path loss
Solution Approach 1:
The patent merges signals from multiple HAPs base stations that are at different distances and positions. By combining connections with both a first base station and a second base station, the system achieves extended coverage while compensating for individual path loss through signal diversity and cooperative communication.
3Area of stationary object
If the HAPs base station moves to maintain coverage, then the coverage area is maintained, but the connection stability deteriorates due to changing path loss
Solution Approach 1:
The patent implements dynamic connection management where the user equipment adapts to moving HAPs base stations. The system continuously monitors base station positions and signal conditions, dynamically adjusting connection parameters and switching between multiple base stations to maintain both coverage and connection stability despite movement.
Solution Approach 2:
The system changes connection parameters such as beam directions, transmission powers, and connection weights based on real-time base station positions and signal conditions. This allows the system to maintain stable connections while accommodating the movement of HAPs base stations through parameter optimization.
4Reliability
If multiple base stations are connected simultaneously, then the connection reliability is improved, but the device complexity increases due to multiple connection management
Solution Approach 1:
The patent implements a universal connection management framework that handles multiple base station connections through a single, integrated process. The user equipment and network device use common protocols and procedures for establishing, maintaining, and managing connections with multiple HAPs base stations, reducing the effective complexity despite the increased number of connections.

AI summary
This disclosure is directed towards improved methods for identifying one or more base stations for connection with user equipment. The user equipment may establish a connection with a base stations based on an estimated location of the base station. Additionally, the user equipment may receive an indication from the base station to scan for additional base stations at additional estimated locations. Further, the user equipment may determine one or more connection parameters (e.g., distance from communication hub to user equipment, angle of communication hub relative to user equipment, shadowing at the communication hub, and the like) associated with the base stations within the geographical area. The user equipment may establish connection with base stations that are determined to have the best signal strength based on the connection parameters.
