Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular systems with wireless backhaul, the existing infrastructure is inflexible and struggles to dynamically change routes or operating methods in response to base station movement or environmental changes, leading to instability and connectivity issues.
Innovation Solution
A mechanism is provided for constructing a flexible wireless backhaul by using a base station with a backhaul control unit that manages wireless communication paths, allowing for the selection of optimal relay stages and frequency resources to ensure stable connections and efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication path is used for backhaul, then stability and reliability are improved, but flexibility and adaptability deteriorate
Solution Approach 1:
The patent applies dynamics by enabling the backhaul route to change dynamically based on terminal device movement. The base station determines whether to switch between wired and wireless backhaul paths in real-time according to terminal location and communication requirements, making the previously static wired backhaul adaptable to changing conditions.
Solution Approach 2:
The base station is designed with multi-functionality to support both wired and wireless backhaul connections. It can selectively use either connection type based on situation, making the system universally applicable to different scenarios - using wired connection for stability when needed and wireless for flexibility when terminals move.
2Adaptability or versatility
If wireless communication path is used for backhaul, then flexibility and adaptability are improved, but stability and reliability deteriorate
Solution Approach 1:
The base station acts as an intermediary that manages the connection between terminal devices and the core network. It intelligently selects whether to use wireless or wired backhaul path, mediating between the need for flexibility (wireless) and stability (wired) by choosing the appropriate path based on terminal location and communication requirements.
Solution Approach 2:
The system changes the backhaul connection parameter dynamically - switching between wired and wireless modes based on determined conditions such as terminal device location. This parameter change allows the system to adapt to different scenarios while maintaining appropriate levels of stability and flexibility.
3Adaptability or versatility
If base station moves or environment changes, then adaptability is improved, but connection stability deteriorates
Solution Approach 1:
The backhaul system is made dynamic by allowing automatic switching between wired and wireless connections when base stations move or environmental conditions change. The base station continuously determines the appropriate backhaul path based on current conditions, enabling the system to adapt to movement and changes while maintaining connection stability.
4Ease of manufacture
If fixed backhaul route is used, then implementation simplicity is improved, but responsiveness to changes deteriorates
Solution Approach 1:
While maintaining simple initial setup like fixed routes, the system becomes dynamic by automatically determining and switching backhaul paths based on terminal device location and communication requirements. This allows the system to start simple but become adaptable when changes occur.
