Stratospheric Communication Control Device for Expanded Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems using flying bodies in the stratosphere face limitations in covering large areas while adhering to 3GPP standards, particularly in terms of the distance between wireless base stations and user terminals.
Innovation Solution
The implementation of a communication control apparatus that configures a flying body to form both an inner wireless communication area with a radius of up to 100 km and an outer wireless communication area with cells having a radius of up to 50 km, thereby expanding the coverage area while maintaining regulatory compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single wireless communication area with radius up to 100 km is formed according to 3GPP standards, then compliance with distance regulations is achieved, but the coverage area is limited and cannot extend beyond the standard distance limit
Solution Approach 1:
The wireless communication area is segmented into two distinct zones: an inner area conforming to 3GPP standards with radius up to 100 km, and an outer area extending beyond the standard limit with cells having radius up to 50 km. This segmentation allows the system to simultaneously maintain regulatory compliance in the inner area while expanding coverage in the outer area.
Solution Approach 2:
Different quality requirements are applied to different regions: the inner wireless communication area maintains strict adherence to 3GPP distance regulations, while the outer wireless communication area implements relaxed distance standards. This local differentiation enables the system to optimize coverage area without compromising compliance in critical regions.
2Area of stationary object
If multiple flying bodies are deployed to expand coverage area, then coverage is improved, but the number of required flying bodies increases and operational costs rise
Solution Approach 1:
Each flying body is equipped with dual functionality: it can operate as a standard 3GPP-compliant base station for the inner area and simultaneously function as an extended coverage node for the outer area. This multi-functionality allows a single flying body to serve multiple purposes, reducing the total number needed compared to deploying separate systems for different coverage zones.
3Area of stationary object
If the distance between wireless base station and user terminal exceeds 100 km, then coverage area is expanded, but compliance with 3GPP timing advance regulations is violated
Solution Approach 1:
The system dynamically adjusts operational parameters based on location within the communication area. For user terminals in the outer area exceeding 100 km distance, the system implements relaxed timing advance regulations specifically adapted for those extended distances, while maintaining standard 3GPP timing requirements for inner area terminals. This dynamic adaptation allows compliance in each respective zone.

AI summary
Provided is a communication control apparatus configured to control communication of a flying body configured to form a wireless communication area by applying a beam toward the ground to provide wireless communication service for a user terminal in the wireless communication area. The communication control apparatus comprises an inner area forming unit configured to form an inner wireless communication area having a radius of about 100 km or shorter; and an outer area forming unit configured to form, on an outer side of the inner wireless communication area, an outer wireless communication area constituted by an outer peripheral cell, the outer peripheral cell having a radius of about 50 km or shorter.
