Solution Overview

Problem

Controlling measurement behavior of a terminal using a measurement time length is adverse to meeting the requirement for quickly activating carrier aggregation (CA) and/or dual connectivity (DC) due to varying service scenarios and network coverage.

Innovation Solution

The terminal is automatically triggered to perform proactive measurements based on advance measurement conditions determined by state information, ensuring an available measurement result upon entering the connected state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a measurement time length is used to control terminal measurement behavior, then the measurement process is simplified and can be configured in advance, but the terminal cannot ensure having available measurement results when entering the connected state, delaying CA/DC activation

Engineering Contradiction:
ImproveConfiguration simplicityVSAvoidCA/DC activation delay
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent applies preliminary action by configuring the terminal to perform measurements in advance while in idle or inactive states, before entering the connected state. The network device configures measurement parameters (frequencies, quantities, areas) ahead of time, and the terminal executes these measurements proactively. This ensures measurement results are ready when the terminal transitions to connected state, eliminating the delay caused by waiting for measurement completion after connection establishment.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the terminal performs measurements only after entering the connected state, then measurement results are guaranteed to be available, but the activation of CA and/or DC is delayed due to the time required for measurement

Engineering Contradiction:
ImproveMeasurement result availabilityVSAvoidCA/DC activation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements preliminary action by having the terminal perform measurements before entering the connected state. The network device sends measurement configurations to the terminal in advance (when the terminal is in idle or inactive state), and the terminal executes measurements proactively. When the terminal transitions to connected state, the measurement results are already available, immediately enabling CA/DC activation without waiting for measurement completion.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies dynamics by making the measurement execution flexible and adaptive. The terminal dynamically adjusts measurement execution based on its current state (idle, inactive, or connected). The network device can dynamically configure measurement parameters and the terminal can dynamically perform measurements at appropriate times, optimizing both reliability and speed of CA/DC activation.

Inventive Principle:
Principle #15Dynamics

3Loss of time

If advance measurement configuration is provided, then the terminal can measure in non-connected state, but the terminal may not have accurate measurement results when needed due to varying service scenarios and network coverage

Engineering Contradiction:
ImproveMeasurement preparation timeVSAvoidMeasurement result accuracy
Core Design Contradiction:
Loss of timeVSMeasurement precision

Solution Approach 1:

The patent applies dynamics by making the measurement process adaptive to varying service scenarios and network conditions. The network device dynamically configures measurement parameters (frequencies, quantities, areas, trigger conditions) based on current network state and service requirements. The terminal dynamically executes measurements based on these configurations and reports results when measurement conditions are met, ensuring both timeliness and accuracy of measurement results.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback mechanisms where the terminal reports measurement results to the network device when measurement trigger conditions are met. The network device receives these feedback reports and uses them to make informed decisions about CA/DC configuration. This feedback loop ensures that the network has accurate, up-to-date measurement information for making optimal deployment decisions.

Inventive Principle:
Principle #23Feedback
