Solution Overview

Problem

Existing wireless telecommunications systems face challenges in providing optimal Quality of Service (QoS) for data transmission, particularly in scenarios with varying data rates and interactive applications, due to suboptimal polling intervals and inefficient resource allocation.

Innovation Solution

A system and method for dynamically setting polling intervals based on the size of data blocks, service priority, and transmission capacity, allowing for adaptive polling to optimize resource usage and QoS in cellular mobile radio telecommunications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed polling intervals are used for data transmission, then system simplicity is maintained, but Quality of Service (QoS) optimization is limited

Engineering Contradiction:
ImproveQoS optimizationVSAvoidpolling interval management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic polling intervals that automatically adjust based on network conditions, data block sizes, and service priorities. The polling interval is no longer fixed but varies adaptively to optimize QoS for different traffic types and network states, resolving the contradiction between adaptability and complexity through automated dynamic adjustment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the polling interval parameter dynamically based on multiple factors including data block size, service priority level, and network capacity. By making this key parameter variable rather than constant, the system achieves QoS optimization for diverse services while the automated parameter adjustment prevents excessive complexity.

Inventive Principle:
Principle #35Parameter changes

2Speed

If polling intervals are shortened to improve responsiveness, then interactive application performance is enhanced, but network resource overhead increases

Engineering Contradiction:
Improveresponse timeVSAvoidnetwork resource overhead
Core Design Contradiction:
SpeedVSLoss of energy

Solution Approach 1:

The polling interval dynamically adapts to service requirements and network conditions. For interactive applications requiring fast response, shorter intervals are automatically applied. For bulk data transfers or lower-priority traffic, longer intervals reduce overhead. This dynamic adjustment resolves the contradiction by matching polling frequency to actual needs rather than using a uniform interval.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different polling intervals are applied to different services, user equipments, or data flows based on their specific QoS requirements. High-priority interactive services receive shorter polling intervals for fast response, while other services use longer intervals to minimize overhead. This localized optimization resolves the contradiction by applying appropriate polling frequencies only where needed.

Inventive Principle:
Principle #3Local quality

3Reliability

If polling is performed frequently to monitor network conditions, then QoS management is improved, but system complexity and processing overhead increase

Engineering Contradiction:
ImproveQoS managementVSAvoidpolling mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The polling mechanism dynamically adjusts its operation based on network conditions and service requirements. Rather than continuous or uniformly frequent polling, the system adapts the polling frequency and depth to match actual QoS needs, improving reliability while avoiding unnecessary processing overhead and complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system applies polling at appropriate levels of frequency and detail based on service requirements. For critical services, more frequent and detailed polling is performed. For less critical traffic, reduced polling is sufficient. This partial action approach achieves adequate QoS management without the excessive complexity of universal frequent polling.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

An apparatus or method for transmitting data blocks on a communications channel having a radio link between two stations including a user equipment comprises receiving first data blocks from the user equipment, and transmitting second data blocks to the user equipment. A polling interval is dynamically set for the transmission of polling messages to the user equipment after transmission of the second data blocks, the polling interval being set in accordance with at least one of: a size of one or more data blocks received by the apparatus from the user equipment, a size of one or more blocks transmitted from the apparatus to the user equipment, and a service to which the user equipment is subscribed. The apparatus may be used as a PCU in a cellular mobile telephone system.
