Solution Overview

Problem

Current wireless telecommunications networks maintain RRC channels with a global timeout value, leading to unnecessary resource consumption as the same timeout value is applied to all user devices regardless of the type of traffic, resulting in inefficient resource usage.

Innovation Solution

Implementing different RRC idle timers based on the type of traffic received from user devices, using Quality of Service (QoS) class indicators (QCIs) to set specific timeout values for each type of traffic, allowing for more precise control over resource usage without significantly impacting network performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a global RRC timeout value is used for all user devices, then the system is simple to manage, but resource consumption increases due to inefficient timeout settings for different traffic types

Engineering Contradiction:
ImproveRRC timeout management complexityVSAvoidPower consumption
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The patent applies local quality by assigning different RRC timeout values to different QCI classes. Instead of using a uniform global timeout, the system tailors the timeout parameter to each traffic type's specific requirements, thereby reducing unnecessary power consumption while maintaining simplicity in management through standardized QoS class definitions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the timeout parameter based on QCI class. By dynamically adjusting the RRC timeout value according to the traffic type (e.g., shorter timeout for signaling traffic, longer timeout for data traffic), the system optimizes power consumption without significantly increasing management complexity.

Inventive Principle:
Principle #35Parameter changes

2Loss of energy

If different RRC timeout values are used for different traffic types, then resource efficiency improves, but system complexity increases

Engineering Contradiction:
ImprovePower consumptionVSAvoidRRC timeout management complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent leverages the existing QoS class indicator framework, which is already universally used for traffic classification in wireless networks. By mapping RRC timeout values to QCI classes, the system reuses an established multi-functional mechanism, avoiding the need for a completely new complex management structure while achieving traffic-type-specific timeout optimization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If a short RRC timeout value is used, then resources are freed quickly, but network performance may be impacted for certain traffic types

Engineering Contradiction:
ImproveResource turnover rateVSAvoidNetwork performance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies local quality by setting appropriate timeout values for each QCI class based on its specific requirements. Critical signaling traffic receives longer timeouts to ensure reliable delivery, while non-critical data traffic uses shorter timeouts for faster resource turnover. This localized optimization resolves the contradiction between resource efficiency and network performance.

Inventive Principle:
Principle #3Local quality

4Reliability

If a long RRC timeout value is used, then network performance is maintained, but resource consumption increases

Engineering Contradiction:
ImproveNetwork performanceVSAvoidResource turnover rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent changes the timeout parameter dynamically based on QCI class. By adjusting the RRC timeout value according to traffic type (shorter for data traffic, longer for signaling traffic), the system achieves both goals: maintaining network performance for critical traffic while improving resource turnover rate for non-critical traffic.

Inventive Principle:
Principle #35Parameter changes

AI summary

A device may be configured to determine a type of traffic, received by the device from a user device; identify a radio resource control (“RRC”) timeout value associated with the type; start an RRC dormancy timer based on the RRC timeout value; and modify, based on expiration of the RRC dormancy timer, an RRC channel between the device and the user device.
