Mobile Node Local Radio Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile telecommunications networks face limitations in network capacity and geographical coverage, particularly in situations requiring fast and reliable information exchange among terminal devices, which can be addressed by implementing device-to-device (D2D) communications and local cell arrangements, but require effective resource allocation and management.
Innovation Solution
A method is introduced for managing radio connections in mobile telecommunications networks by activating a limited local radio connection between a terminal and a mobile node, starting a timer, and upon expiration, activating a limited base station radio connection while terminating the local connection, thereby optimizing resource allocation and improving network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If device-to-device (D2D) communications are implemented to improve network capacity and coverage, then the ability for terminal devices to exchange information directly is enhanced, but resource allocation and management complexity increases
Solution Approach 1:
The patent introduces a timer mechanism as an intermediary control element that automatically manages the transition between local and base station radio connections. This intermediary automates resource allocation decisions, reducing the complexity of manual resource management while enabling D2D communications to improve network capacity.
Solution Approach 2:
The patent implements dynamic resource allocation by allowing radio connections to switch between local D2D mode and base station mode based on timer expiration. This dynamic adjustment optimizes network capacity for D2D communications while automatically adapting resource allocation to current network conditions, reducing management complexity.
2Area of stationary object
If local cell arrangements are deployed to expand geographical coverage, then the coverage area increases, but the complexity of managing multiple radio connections increases
Solution Approach 1:
The patent employs periodic timer-based actions to automatically manage local cell connections. The timer creates periodic evaluation points where the system decides whether to maintain local radio connections or revert to base station connections, simplifying the management of expanded coverage areas through automated periodic reassessment rather than continuous complex management.
Solution Approach 2:
The local cell arrangement uses self-service mechanisms where the timer automatically triggers connection transitions without requiring complex external coordination. The system serves itself by automatically managing connection states based on timer expiration, reducing the complexity of managing multiple radio connections across expanded coverage areas.
3Loss of energy
If limited local radio connections are activated to optimize resource allocation, then spectrum efficiency improves, but the complexity of connection state management increases
Solution Approach 1:
The patent extracts the complexity of connection state management by isolating it into a simple timer mechanism. The timer is separated from the complex resource allocation logic, providing a clear, simple trigger point for state transitions. This extraction reduces connection state management complexity while maintaining spectrum efficiency improvements from limited local radio connections.
4Loss of information
If timers are used to automatically transition between connection states, then signaling overhead is reduced, but the precision of connection timing control becomes fixed and less flexible
Solution Approach 1:
The patent uses fixed-duration timers as simple, disposable control elements that expire after a predetermined time. These timers provide sufficient timing control precision for connection state transitions without requiring complex adjustable mechanisms. The fixed nature of the timers reduces signaling overhead while providing adequate timing precision for the application requirements.
