Dynamic Resource Partitioning in Cellular RNC Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular communication systems, such as UMTS, face inefficiencies in resource allocation between different service types like HSDPA and R99, leading to suboptimal Quality of Service and capacity utilization due to fixed resource partitioning that does not adapt to dynamic service requirements.
Innovation Solution
A system with separate resource controllers for each service type and a resource partitioner that dynamically adjusts resource allocation based on admission failure measures, reallocating resources from one service type to another when certain thresholds are exceeded, ensuring that resource usage reflects the varying demands of different communication services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed resource partitioning is used between HSDPA and R99 services, then resource allocation is simple and stable, but resource utilization efficiency deteriorates and Quality of Service becomes suboptimal
Solution Approach 1:
The patent implements dynamic resource partitioning where the RNC continuously monitors admission failure rates of HSDPA and R99 services and adjusts resource allocation proportions accordingly. The system transitions from static fixed partitioning to dynamic adaptive partitioning, allowing resource shares to change in response to real-time service demands and admission failures, thereby resolving the contradiction between allocation simplicity and utilization efficiency.
Solution Approach 2:
The patent establishes a feedback mechanism where the RNC monitors admission failure rates from both HSDPA and R99 services and uses this information to adjust resource allocation. The feedback loop continuously measures performance metrics and modifies resource partitioning to optimize both service quality and resource efficiency, transforming the resource allocation from an open-loop fixed value to a closed-loop adaptive system.
2Stability of the object's composition
If fixed resource partitioning is used, then system stability is maintained, but adaptability to dynamic service requirements deteriorates
Solution Approach 1:
The system implements dynamic resource partitioning that adapts to changing service conditions. The RNC continuously adjusts resource allocation proportions based on real-time admission failure rates and service demands, allowing the system to maintain stability through controlled, measured adjustments rather than abrupt changes, thus resolving the contradiction between stability and adaptability.
Solution Approach 2:
The patent changes the allocation proportion parameter dynamically based on monitored admission failure rates. By adjusting the resource allocation proportion as a variable parameter rather than a fixed value, the system can adapt to different service conditions while maintaining overall stability through gradual, monitored changes, eliminating the need for completely fixed partitioning.
3Reliability
If resources are allocated to prevent admission failures, then Quality of Service improves, but resource wastage increases when services do not fully utilize allocated resources
Solution Approach 1:
The system uses feedback from admission failure rate monitoring to adjust resource allocation dynamically. When admission failures occur, the system reallocates resources to prevent further failures; when services operate smoothly with low failure rates, the system optimizes resource distribution to prevent wastage. This feedback-driven adaptive allocation resolves the contradiction between reliability and resource efficiency.
Solution Approach 2:
The patent dynamically changes resource allocation parameters based on actual service performance metrics. By adjusting allocation proportions in response to monitored admission failure rates and service utilization patterns, the system prevents both resource wastage and admission failures, optimizing the balance between reliability and efficient resource usage.
