Solution Overview

Problem

Conventional telecommunications networks fail to provide specialized treatment for priority bearers, leading to poor uplink performance and user experience issues, particularly affecting emergency services and VIP users.

Innovation Solution

Implement an uplink performance optimization module that detects uplink-only problems, ranks bearers based on priority levels, and applies corrective actions such as parameter adjustments and resource management to enhance uplink quality for priority bearers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional techniques are used to improve uplink performance, then general uplink quality is enhanced, but priority bearers are not specially treated and still suffer from low quality communication

Engineering Contradiction:
Improveuplink communication qualityVSAvoidbearer-specific treatment capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by implementing bearer-specific processing within the general uplink improvement framework. The network entity identifies priority bearers and applies specialized techniques such as adjusted resource allocation, modified power control parameters, or enhanced modulation schemes specifically to these high-priority bearers, while other bearers receive standard treatment. This ensures that priority bearers get enhanced reliability without requiring complete system redesign.

Inventive Principle:
Principle #3Local quality

2Reliability

If specialized treatment is applied to priority bearers, then user experience for high-priority services is improved, but network complexity increases

Engineering Contradiction:
Improvepriority bearer communication qualityVSAvoidnetwork entity processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-configuring priority bearer identifiers and associated treatment parameters in the network entity before actual data transmission begins. The system pre-establishes which bearers require enhanced treatment based on QoS parameters, ARP values, or service type, and pre-loads the appropriate handling algorithms. This reduces real-time processing complexity while maintaining specialized treatment for priority bearers.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If ARP priority level is used to determine bearer creation, then resource allocation decisions are made, but ARP does not affect packet delivery priority once bearer is created

Engineering Contradiction:
Improvebearer creation efficiencyVSAvoidpacket delivery quality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies feedback by continuously monitoring packet delivery performance for different bearers and adjusting resource allocation dynamically. The network entity tracks metrics such as packet loss rate, throughput, and delay for each bearer, and uses this feedback to reallocate resources in favor of priority bearers that are experiencing degraded service. This creates a closed-loop system where ARP priority levels continuously influence resource allocation based on actual delivery quality, not just initial bearer creation decisions.

Inventive Principle:
Principle #23Feedback

AI summary

A system and method for detecting and correcting uplink-only problems is disclosed. The system comprises one or more of the following modules: uplink problem detection module, maximum permissible limit module, and uplink improvement calculation and actions module. The uplink problem detection module detects uplink-only problems using values of one or more parameters related to bearer performance. For instance, the uplink problem detection module continuously monitors the uplink performance by checking uplink transmission error and when a threshold is crossed, declares an uplink problem. The maximum permissible limit module limits the actions by uplink improvement calculation and actions module so that other parts in the system are not negatively affected. The uplink improvement calculation and actions module determines and performs the actions to improve the uplink transmission error situation detected by the uplink problem detection module.
