Solution Overview

Problem

Conventional cell selection processes in wireless communication systems fail to consider the data use pattern of user equipment, leading to inefficient network management and service provision, as they rely solely on signal strength without accounting for varying data usage patterns and user speeds.

Innovation Solution

A method where user equipment generates data use pattern information based on moving speed and amount of data used, receives data providing pattern information from the network, and determines an access type to select an appropriate cell type, such as macro or small cells, based on these patterns, enabling more efficient cell selection and reselection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cell selection is based solely on signal strength (RSRP/RSSI), then the cell selection process is simple and fast, but it does not account for varying data usage patterns and user speeds, leading to inefficient network management and service provision

Engineering Contradiction:
Improvecell selection process simplicityVSAvoidnetwork management efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent introduces new parameters (data usage amount, user speed) to the cell selection process beyond traditional signal strength metrics. The UE determines its data usage pattern and speed, then selects cells based on these additional parameters, transforming the selection criteria from single-dimensional (signal strength) to multi-dimensional (signal strength + data usage + speed)

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The cell selection process becomes dynamic by continuously monitoring data usage patterns and user speed. The UE adapts its cell selection strategy based on real-time conditions, switching between different cell types (macro vs. small cells) depending on the current data usage scenario and mobility state

Inventive Principle:
Principle #15Dynamics

2Productivity

If cell selection considers data usage pattern and user speed, then network management efficiency and service quality improve, but the cell selection process becomes more complex

Engineering Contradiction:
Improvenetwork management efficiencyVSAvoidcell selection process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the cell selection process into distinct phases: (1) signal strength measurement, (2) data usage pattern determination, (3) user speed measurement, (4) cell type selection based on combined criteria. This segmentation allows each sub-process to be handled independently, managing complexity through structured decomposition

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If user equipment continuously monitors data usage and speed for cell selection, then cell selection accuracy improves, but energy consumption increases

Engineering Contradiction:
Improvecell selection accuracyVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The UE performs measurements and monitoring at appropriate levels - not continuously at maximum intensity, but sufficiently often to capture meaningful changes in data usage patterns and speed. The system balances measurement frequency with energy conservation by triggering detailed monitoring only when necessary for accurate cell selection

Inventive Principle:
Principle #16Partial or excessive action
