Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies fail to enable terminal devices to perform early measurement when moving out of configured validity areas, leading to disrupted dual connectivity and carrier aggregation processes.
Innovation Solution
A method and apparatus that allow terminal devices to receive multiple measurement configurations, enabling them to continue measuring and reconfigure based on new cell selections, even when moving out of initial validity areas, by using timers and flexible validity area configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device receives only one early measurement configuration with a fixed validity area, then the configuration is simple to manage, but the terminal device cannot perform early measurement when moving out of the validity area, disrupting dual connectivity and carrier aggregation processes
Solution Approach 1:
The patent divides the measurement configuration into multiple independent configurations, each associated with a specific validity area. When the terminal device moves to a new validity area, it can selectively apply the corresponding measurement configuration rather than being limited to a single configuration. This segmentation allows the system to maintain multiple measurement settings without creating a single overly complex configuration.
Solution Approach 2:
The patent introduces dynamic validity area indicators that change based on the terminal device's current location. The measurement configuration is no longer static but adapts dynamically as the device moves between different validity areas. This dynamic approach enables continuous early measurement capability while keeping individual configuration instances manageable in size.
2Productivity
If the terminal device stops early measurement when moving out of the validity area, then the measurement configuration remains simple, but dual connectivity and carrier aggregation cannot be established quickly
Solution Approach 1:
The patent pre-configures multiple measurement configurations in advance, each tailored to a specific validity area. When the terminal device enters a new validity area, the corresponding pre-configured measurement settings are immediately activated without requiring time-consuming reconfiguration. This preliminary preparation enables rapid establishment of dual connectivity and carrier aggregation while avoiding the need for complex real-time configuration generation.
3Adaptability or versatility
If multiple measurement configurations are introduced to support multiple validity areas, then the terminal device can maintain early measurement capabilities across different areas, but the complexity of managing measurement configurations increases
Solution Approach 1:
The patent implements a feedback mechanism where the terminal device reports its current validity area indicator to the network. Based on this feedback, the network can provide guidance on which measurement configuration to use, reducing the burden on the terminal device to manage multiple configurations independently. This feedback loop simplifies operation by allowing the system to coordinate configuration selection based on actual device location.

AI summary
Example measurement methods and apparatus are described. One example method includes obtaining a timer by a terminal device. The terminal device obtains two or more measurement configurations, where each of two or more measurement configurations includes a validity area and a measurement frequency corresponding to the validity area, and the validity area includes one or more cells. The terminal device measures, based on the measurement configuration, a measurement frequency corresponding to a validity area that matches a cell on which the terminal device camps, where the terminal device is in an idle state or in an inactive state, and the timer is not stopped and has not expired.
