Solution Overview

Problem

Conventional communication systems face inefficiencies in managing uplink and downlink capacities, as existing traffic policing techniques cannot adaptively adjust capacity limits and often result in mismatched demand and allocated ratios, leading to dropped surplus traffic and inefficient resource utilization.

Innovation Solution

A method for dynamically assigning uplink and downlink capacities based on available channel capacity, using a grant server mechanism to regulate traffic streams and ensure compliance with negotiated contracts, allowing for adaptive adjustments and efficient use of shared communication resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional traffic policing techniques are used to enforce separate uplink and downlink capacity limits, then capacity limits are enforced, but resource utilization efficiency deteriorates due to inability to adaptively adjust capacity limits

Engineering Contradiction:
Improvecapacity limit enforcementVSAvoidresource utilization efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements dynamic capacity allocation where the access point continuously monitors uplink and downlink traffic demands, then adjusts capacity limits adaptively. Instead of fixed separate limits, the system dynamically reallocates capacity between uplink and downlink based on current network conditions and user requirements, resolving the contradiction between enforcing limits and utilizing resources efficiently

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameters of capacity allocation by transitioning from static contracted capacity limits to dynamic capacity assignment. The access point modifies uplink and downlink capacity parameters in real-time based on observed traffic patterns, allowing the system to maintain reliability through controlled capacity enforcement while improving productivity through adaptive resource optimization

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If fixed uplink and downlink capacity limits are allocated, then capacity allocation is simple, but mismatch between demand and allocated ratio occurs leading to surplus traffic drops

Engineering Contradiction:
Improvecapacity allocation simplicityVSAvoidtraffic utilization efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system performs preliminary capacity allocation based on contracted service level agreements, establishing initial uplink and downlink limits. This preliminary action provides a simple baseline allocation that satisfies basic service requirements while enabling subsequent adaptive adjustments when traffic patterns deviate from expectations, preventing surplus traffic drops

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If separate uplink and downlink capacity policing is implemented, then individual capacity control is achieved, but adaptability to varying traffic demands deteriorates

Engineering Contradiction:
Improveindividual capacity controlVSAvoidadaptive capacity adjustment
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The access point implements feedback mechanisms by monitoring actual uplink and downlink traffic demands continuously. Based on this feedback, the system adjusts capacity allocation dynamically, maintaining ease of operation through automated control while achieving adaptability to varying traffic patterns. The feedback loop enables the system to respond to changing conditions without complex manual intervention

Inventive Principle:
Principle #23Feedback
