Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular radio networks face challenges in providing flexible and adaptive radio coverage, especially in areas where static base stations are not available or are overwhelmed, such as private households, underground car parks, and remote locations, due to varying demand and technical limitations.
Innovation Solution
An ultra-small cell base station for vehicles that can operate multiple small cells using different antenna assemblies to provide flexible and adaptive radio coverage, allowing simultaneous or independent operation of cells within the vehicle and surrounding areas, and can be easily activated or deactivated based on demand and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static cellular radio base stations are deployed to provide comprehensive radio coverage, then network coverage is improved, but equipment costs and site rental costs increase
Solution Approach 1:
The patent applies the dynamics principle by transforming static base stations into mobile base stations mounted on vehicles. The base station can move to different locations to provide radio coverage dynamically, eliminating the need for multiple fixed installations. This reduces equipment costs and site rental costs while maintaining comprehensive coverage through the mobile platform's ability to relocate as needed.
Solution Approach 2:
The mobile base station system performs multiple functions: it can serve as a primary base station, a relay station, or a roaming base station depending on network conditions. The system can adapt its role and coverage area dynamically, providing universal service across different locations and scenarios, thereby reducing the need for dedicated fixed infrastructure at each site.
2Reliability
If static base stations are configured with complex antenna alignment and power settings to meet network capacity requirements, then radio provision is improved, but device complexity and operational complexity increase
Solution Approach 1:
The mobile base station employs dynamic configuration where antenna alignment and power settings are automatically adjusted based on real-time network conditions, vehicle position, and demand. This eliminates the need for complex manual configuration and ongoing maintenance of fixed antenna systems, reducing operational complexity while maintaining reliable radio provision.
Solution Approach 2:
The base station system performs self-configuration and self-optimization through automated algorithms that adjust transmission parameters, antenna orientation, and power levels based on detected network conditions and user demand. This self-service capability reduces the need for complex manual intervention and specialized configuration procedures.
3Productivity
If multiple static base stations are deployed to handle varying demand at different locations and times, then network capacity is improved, but equipment costs and operational complexity increase
Solution Approach 1:
Instead of deploying multiple fixed base stations to handle varying demand, the patent uses a mobile base station that can physically relocate to different areas based on real-time demand patterns. This dynamic positioning allows a single or fewer units to serve multiple locations sequentially, maintaining network capacity while significantly reducing equipment costs compared to installing permanent infrastructure at each high-demand location.
Solution Approach 2:
The system enables temporary deployment of base station functionality at specific locations only when and where needed, rather than maintaining permanent fixed installations. The mobile platform can be deployed to high-demand areas during peak periods and relocated or returned to base when demand decreases, optimizing resource utilization and reducing overall equipment requirements.

AI summary
An ultra-small cell base station for a vehicle is coupleable, for signal exchange, to a first antenna assembly, which is configured to receive radio signals of a cellular radio user device situated inside the vehicle and to emit radio signals to be received by the user device. The ultra-small cell base station is also coupleable to a second antenna assembly, configured to receive radio signals of a further cellular radio user device situated outside the vehicle and to emit radio signals to be received by the further user device. The ultra-small cell base station is also coupleable to a network-side antenna assembly of the vehicle configured to receive radio signals emitted by a pre-defined static cellular radio base station and to emit radio signals to be received by the static base station. The ultra-small cell base station is configured to operate a first and a second small cell.
