Solution Overview

Problem

In 5G communication systems, determining cell quality information is inaccurate when network devices save energy by sending SSBs at multiple frequencies, as existing methods do not comprehensively consider measurement values across these frequencies.

Innovation Solution

A method for determining cell quality information by comprehensively considering measurement values of multiple SSBs associated with a cell, using coefficients and thresholds to improve accuracy, and incorporating frequency domain offsets to align reference points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If user experience information is collected from multiple dimensions (signal quality, throughput, packet loss, etc.), then the accuracy of network quality assessment is improved, but the complexity of data collection and processing increases

Engineering Contradiction:
Improvenetwork quality assessment accuracyVSAvoiddata collection and processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple quality assessment dimensions (signal quality, throughput, packet loss, call drop, etc.) into a unified user experience information collection framework. The network side and terminal side collaborate to gather data from various sources and integrate them through a joint processing mechanism, merging disparate data streams into comprehensive quality assessments without requiring separate complex systems for each dimension.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal user experience information collection and processing mechanism that handles multiple types of quality data (signal quality, throughput, packet loss, call drop, service type information) through a single integrated framework. This multi-functional system can assess different quality dimensions using the same basic architecture, reducing overall system complexity while maintaining comprehensive monitoring capabilities.

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

2Ease of manufacture

If traditional separate assessment methods are used for different quality dimensions, then implementation simplicity is maintained, but the comprehensiveness of network quality monitoring deteriorates

Engineering Contradiction:
Improveimplementation simplicityVSAvoidnetwork quality monitoring comprehensiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent segments the quality assessment process into two coordinated parts: terminal-side collection (gathering raw quality data) and network-side processing (analyzing and generating assessments). This segmentation allows each side to perform its function with relative simplicity while the combined system achieves comprehensive monitoring. The terminal handles basic data collection, and the network handles complex analysis, dividing the comprehensive task into manageable segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a nested structure where terminal-side quality information collection is embedded within the broader network-side processing framework. The terminal collects and pre-processes quality data, which is then nested into the network's comprehensive analysis system. This nested arrangement allows the simpler terminal function to be contained within the more comprehensive network system, achieving both simplicity at each level and comprehensiveness overall.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A method for determining cell quality information and an apparatus are provided, and relate to the field of communication technologies. The method includes: A terminal device receives first information from a first network device, where the first information indicates that a first cell is associated with a first SSB and a second SSB, and frequency information of the first SSB is different from frequency information of the second SSB; and the terminal device determines quality information of the first cell based on a measurement value of the first SSB and a measurement value of the second SSB. In this manner, after learning, based on the first information sent by the first network device, that the first cell is associated with the two SSBs, the terminal device may determine the quality information of the first cell by comprehensively considering the measurement values of the two SSBs, so that accuracy of determining the cell quality information can be effectively improved.
