Dynamic Air Interface Resource Exchange Between Communication Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for dynamic allocation of shared air interface resources in wireless communication systems result in suboptimal resource sharing and performance due to static allocation methods that fail to adapt to varying network requirements, leading to complexity and inefficiency.
Innovation Solution
An apparatus and method for temporary resource allocation between communication networks, allowing networks to offer and receive resource exchanges, enabling flexible and efficient sharing by selecting the network with the highest offer value and adjusting resource allowances accordingly, facilitating dynamic and real-time spectrum sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static resource allocation is used, then device complexity is reduced, but resource sharing efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where networks can temporarily exchange air interface resources based on real-time needs. The resource allocation is no longer static but adapts dynamically through offer messages and temporary allocation mechanisms, resolving the contradiction between simplicity and efficiency.
Solution Approach 2:
Each network independently determines its resource needs and sends offer messages to request temporary resources from other networks. The system enables self-service resource allocation where networks autonomously negotiate and exchange resources without complex centralized control, maintaining simplicity while improving efficiency.
2Productivity
If dynamic resource allocation is implemented, then resource sharing efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the resource allocation process into independent offer messages exchanged between networks. Each network independently evaluates its needs and sends targeted offers, breaking down the complex allocation problem into simple, manageable transactions that improve efficiency without overwhelming complexity.
Solution Approach 2:
The system changes the parameter of resource allocation from fixed to temporary and adjustable. Networks can modify resource allocation parameters dynamically through offer messages, allowing efficient adaptation to changing conditions while maintaining operational simplicity through standardized message exchanges.
3Adaptability or versatility
If temporary resource reallocation is performed, then adaptability is improved, but loss of time increases due to coordination overhead
Solution Approach 1:
The patent implements preliminary action by having networks send offer messages in advance to indicate resource needs before actual resource allocation is required. This proactive approach allows resources to be pre-coordinated and allocated smoothly, reducing actual coordination time when resources are needed while maintaining high adaptability.

AI summary
An apparatus for resource sharing between a plurality of communication networks (103, 107, 111) each having a nominal resource allocation of a shared air interface resource and a resource exchange allowance is provided. The apparatus (201) comprises a sharing instigation processor (205) which initiates a temporary resource allocation of a first air interface resource from a nominal resource allocation of a first network (103). A network interface (201) receives offer messages from a plurality of networks (107, 111). Each offer message comprises a resource exchange offer value for at least part of the first air interface resource. A selection processor (207) selects a second network (107) for example by selecting the highest offer value for a given resource. An allocation message generator (211) transmits a resource allocation message to the second network (107) indicating a temporary allocation of at least part of the first air interface resource. The resource exchange allowance of the second network (107) is then reduced by a value corresponding to the resource exchange offer value from the second network (107).
