Radio Resource Allocation for Application Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio resource allocation methods in cellular networks, such as overprovisioning, lead to inefficient use of resources and increased complexity, as they rely on average bit rate guarantees rather than ensuring individual application transaction success, causing temporary connectivity issues and increased costs.
Innovation Solution
A method and device for identifying application transactions within data units and dynamically controlling radio resource allocation to ensure compliance with transaction service agreements, which specify guaranteed performance characteristics for each transaction, thereby optimizing resource use and ensuring reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If overprovisioning is employed to ensure application connectivity, then reliability of application communication is improved, but device complexity and operating costs increase
Solution Approach 1:
The patent segments the radio resource allocation process into two distinct phases: a guaranteed minimum allocation phase that ensures baseline connectivity, and a dynamic supplemental allocation phase that responds to actual application transaction needs. This segmentation allows the system to maintain reliability through the guaranteed phase while avoiding excessive complexity by only activating dynamic adjustments when necessary.
Solution Approach 2:
The patent introduces dynamic radio resource allocation that adjusts resource allocation in real-time based on detected application transaction requirements. The system transitions from static overprovisioning to dynamic adaptation, where resources are allocated based on actual need rather than predetermined thresholds, reducing unnecessary complexity while maintaining connectivity reliability.
2Reliability
If overprovisioning is employed to ensure application connectivity, then reliability of application communication is improved, but loss of energy increases
Solution Approach 1:
The patent implements dynamic radio resource allocation that actively monitors application transaction requirements and adjusts resource allocation accordingly. This dynamic approach prevents continuous energy consumption associated with static overprovisioning, as resources are allocated only when application transactions are detected and require support, thereby reducing overall energy loss while maintaining connectivity reliability.
Solution Approach 2:
The patent enables the system to discard (reduce or release) radio resources when application transactions are not active or require minimal support, and recover (reallocate) these resources for other uses. This cyclical allocation pattern prevents wasteful energy consumption by ensuring resources are not continuously allocated at maximum levels when not needed for maintaining application connectivity.
3Device complexity
If transmission service agreements specify guaranteed bit rate on average, then device complexity is reduced, but reliability of individual application transactions deteriorates
Solution Approach 1:
The patent segments the QoS guarantee into two components: a simple average bit rate guarantee that maintains low complexity, and a transaction-specific reliability mechanism that detects individual application transactions and provides targeted resource allocation. This segmentation allows the system to maintain low overall complexity while improving transaction reliability through selective intervention.
Solution Approach 2:
The patent introduces an intermediary detection and control mechanism that monitors data units for application transaction signatures and mediates between the simple average bit rate service agreement and the actual transaction requirements. This intermediary layer enables reliable individual transaction communication without requiring complete redesign of the service agreement framework, thus maintaining simplicity while improving reliability.
