Solution Overview

Problem

The evolution of network architecture from homogeneous to heterogeneous networks, where multiple access points may not connect to a single base station, requires optimization of measurement and communication processes to ensure efficient mobility management, resource allocation, and interference coordination.

Innovation Solution

A measuring method and apparatus that configure and transmit measurement configuration information to user equipment (UE) with enhanced measurement report triggering conditions, allowing the UE to report signal quality measurements based on specific conditions related to multiple base stations, including signal quality thresholds and periodic reporting, to optimize mobility management and resource allocation in heterogeneous networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple access points connect to different base stations in heterogeneous networks, then network capacity and coverage are improved, but measurement and mobility management complexity increases

Engineering Contradiction:
Improvenetwork architecture adaptabilityVSAvoidmeasurement management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the measurement management process by introducing separate reference cell measurement and neighbor cell measurement mechanisms. The network can configure different measurement parameters, reporting conditions, and evaluation criteria for reference cells versus neighbor cells, allowing independent optimization of each measurement type in heterogeneous network scenarios

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes measurement parameters dynamically based on network configuration. Different measurement identities (measId) can be assigned to different cell types (reference or neighbor), with configurable reporting conditions, thresholds, and periodicity. This parameter flexibility allows the system to adapt measurement behavior to the specific heterogeneous network architecture without increasing overall complexity

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If measurement reporting conditions are simplified, then UE processing is reduced, but measurement precision and mobility management accuracy deteriorate

Engineering Contradiction:
ImproveUE measurement processingVSAvoidsignal quality reporting accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent introduces dynamic measurement reporting mechanisms where the UE can be configured with multiple measurement identities, each associated with different reporting conditions (A3, A4, A5 events), thresholds, and periodicity. The network can dynamically adjust which measurements are reported and under what conditions, optimizing the balance between UE processing load and measurement precision based on current network state

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The network performs preliminary configuration of measurement parameters, including pre-defining reporting conditions and thresholds for different cell types. This preliminary setup allows the UE to efficiently process measurements without needing to make complex decisions in real-time, while still achieving high measurement precision through carefully pre-configured reporting criteria

Inventive Principle:
Principle #10Preliminary action
