Admission Control Function Optimizing Wireless Connection Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wireless networks unfairly allocate wireless connection resources, leading to inefficient use due to prioritization based solely on bit rate, resulting in UEs with poor connection quality consuming excessive resources, blocking other UEs with good quality from accessing necessary resources for routine data transfers.
Innovation Solution
Implement a modified admission control function that calculates wireless connection efficiency by comparing the ratio of bit rate to required resources for both requested and existing bearer reservations, preempting less efficient reservations to allocate resources more efficiently, especially favoring multicast and broadcast over unicast when possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bearer reservations are allocated based solely on requested bit rate, then higher bit rate requests are prioritized, but wireless connection resources are unfairly consumed by UEs with poor connection quality
Solution Approach 1:
The patent introduces a new parameter 'wireless connection efficiency' that combines bit rate with connection quality metrics (such as signal-to-noise ratio or path loss). This efficiency parameter dynamically adjusts resource allocation by changing the evaluation criterion from pure bit rate to a composite metric that accounts for both throughput and connection conditions, preventing poor-quality connections from monopolizing resources
Solution Approach 2:
The system implements feedback mechanisms where the admission control function continuously monitors wireless connection quality metrics and adjusts bearer reservation decisions accordingly. The efficiency calculation incorporates real-time connection state information, creating a closed-loop control system that adapts resource allocation based on actual connection conditions rather than static bit rate requests alone
2Reliability
If a UE with poor wireless connection quality is admitted with high bit rate request, then that UE receives sufficient resources, but other UEs with good connection quality are blocked from accessing resources
Solution Approach 1:
The patent applies local quality by differentiating resource allocation based on individual UE connection characteristics. Each UE's bearer reservation decision is evaluated against its specific wireless connection quality metrics, allowing the system to optimize allocations locally for each user rather than applying uniform rules. This enables good-quality UEs to receive appropriate resources while limiting allocations for poor-quality UEs that would otherwise block the system
3Ease of operation
If admission control only considers requested bit rate, then simple allocation decisions are made, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent transforms the admission control decision parameter from a single dimension (requested bit rate) to a multi-dimensional efficiency metric that incorporates connection quality. This parameter transformation maintains operational simplicity by providing a single efficiency value for comparison, while internally accounting for multiple factors including bit rate, signal quality, and resource requirements, thus improving efficiency without significantly complicating the decision process

AI summary
A method and apparatus for granting wireless connection resources for a UE within a communication system is provided herein. During operation, an application requests allocation of wireless communication resources (a bearer reservation) to sustain transmission at a specified bit rate across the communication system via an admission control function. In response to the bearer reservation request, an admission control function calculates a wireless connection efficiency as a function of the requested bit rate and an amount of shared wireless connection resources required to sustain the requested bit rate given the current wireless connection quality associated with the UE. The wireless connection efficiency is then utilized to determine whether or not to admit the bearer reservation request.
