Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heterogeneous radio communication systems, efficient radio resource management across diverse communication systems is challenging due to inflexible and complex centralized resource management, making it difficult to achieve efficient resource sharing and optimization, especially in geographic areas.
Innovation Solution
A wireless communication unit receives geographical radio resource tokens from a token controller, allowing it to determine radio resource usage parameters, enabling decentralized management while maintaining centralized control, thus facilitating flexible and efficient radio resource allocation and optimization across different communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If centralized resource management is applied in traditional radio communication systems, then resource allocation control is maintained, but the system becomes inflexible and complex when adapting to heterogeneous communication systems
Solution Approach 1:
The patent segments resource management into two parts: centralized allocation of geographical radio resource tokens by the network, and decentralized determination of radio resource usage parameters by wireless communication units. This segmentation allows the system to maintain centralized control while enabling flexible local decisions, resolving the contradiction between adaptability and complexity in heterogeneous systems.
Solution Approach 2:
The patent introduces a new dimension of geographical area-based resource management by allocating radio resource tokens specific to particular geographical areas. This geographical dimension allows the system to adapt to different communication systems and environments without increasing overall management complexity, as each unit independently applies the token-based control to its local context.
2Adaptability or versatility
If centralized resource management is modified to allow resource sharing between different communication systems, then resource sharing capability is improved, but the system becomes inflexible and cumbersome
Solution Approach 1:
The patent enables wireless communication units to autonomously determine radio resource usage parameters based on the geographical radio resource tokens they receive. This self-service approach eliminates the need for complex centralized coordination for each resource sharing decision, making the system both more capable of resource sharing and easier to operate, as each unit independently makes optimal decisions within its allocated rights.
3Device complexity
If distributed radio resource management is implemented, then flexibility and reduced complexity are achieved, but centralized control and optimization are reduced
Solution Approach 1:
The patent implements a feedback mechanism where wireless communication units determine radio resource usage parameters based on the geographical radio resource tokens received from the network. The network maintains centralized control by allocating tokens that reflect overall system conditions and optimization goals, while units provide feedback through their local decisions. This feedback loop ensures centralized optimization is maintained while benefiting from distributed flexibility and reduced complexity.
4Adaptability or versatility
If inter system resource management functionality is introduced, then resource sharing between systems is improved, but implementation complexity increases
Solution Approach 1:
The patent creates a universal geographical radio resource token mechanism that can be applied across different communication systems and heterogeneous networks. This universal approach allows inter-system resource management to be implemented without system-specific complex functionality, as the token-based mechanism provides a standardized, easily implementable solution that works across diverse communication systems while maintaining adaptability.

AI summary
A wireless communication unit (101) for a radio communication system comprises a device token controller (403) which receives at least a first geographical radio resource token allocated to the wireless communication unit (101) by a radio resource token controller (117) of a network of the radio communication system. The first geographical radio resource token provides a first radio resource right allocation to the wireless communication unit (101) for a first geographical area. A radio resource manager (407) then determines a radio resource usage parameter in response to the first radio resource right allocation. Specifically, the radio resource manager (407) may only determine the radio resource usage parameter in response to the first radio resource right allocation if the location estimate is within the first geographical area. The radio communication system may be a heterogeneous communication system. The invention may allow effective overall centralized radio resource management while allowing distributed radio resource management procedures and techniques to be used.
