Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In wireless communication networks, when a terminal device is connected to a serving cell with good quality, insufficient uplink or downlink resource scheduling can prevent cell switching, leading to a hanging state.

Innovation Solution

A method and device for transmitting a measurement reconfiguration message that includes indicating insufficient uplink or downlink grant resources and incorporating a measurement event A7 to facilitate cell switching by re-measuring nearby cells.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cell switching is performed based on serving cell quality, then connection reliability is improved, but resource scheduling flexibility deteriorates

Engineering Contradiction:

Improveconnection reliabilityVSAvoidresource scheduling flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The network device pre-configures measurement parameters including event A7 thresholds and resource grant limits before the terminal enters a hanging state. When resource insufficiency is detected, the terminal can immediately trigger cell switching based on pre-established measurement criteria, eliminating the need for real-time decision-making and enabling faster response to resource constraints.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Measurement event A7 serves as an intermediary mechanism between resource scheduling status and cell switching decisions. The event triggers when the difference between serving cell and neighbor cell quality exceeds a threshold, providing a standardized trigger condition that bridges resource status monitoring and cell reselection, enabling automated response to resource insufficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If measurement reconfiguration message is transmitted frequently, then cell switching responsiveness is improved, but signaling overhead increases

Engineering Contradiction:

Improvecell switching responsivenessVSAvoidsignaling overhead

Core Design Contradiction:

SpeedVSQuantity of substance

Solution Approach 1:

The terminal performs periodic measurements of serving cell and neighbor cell qualities according to configured measurement intervals. Event A7 is triggered only when the quality difference exceeds the configured threshold during these periodic measurements, enabling responsive cell switching while avoiding continuous signaling and reducing overhead compared to event-driven continuous monitoring.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The network device configures specific parameters including measurement thresholds, resource grant limits, and event A7 criteria. By adjusting these parameters, the system optimizes the balance between switching responsiveness and signaling overhead - higher thresholds reduce false triggers and overhead, while lower thresholds improve responsiveness.

Inventive Principle:

Principle #35Parameter changes

AI summary

A method of transmitting a measurement reconfiguration message, including: transmitting indication information to a network device, wherein the indication information is configured to indicate that at least one of an uplink grant resource or a downlink grant resource is insufficient; and receiving the measurement reconfiguration message transmitted by the network device, where the measurement reconfiguration message includes a measurement event A7 for switching a cell.
