Solution Overview

Problem

In 5G network environments, terminal devices experience increased power consumption due to 'Ping-Pong' cell reselection between cells with differing priority settings, leading to battery life deterioration, and adjusting network parameters is costly and difficult to implement.

Innovation Solution

A control method and device that record reselection information and disable reporting if it meets preset conditions, such as excessive connection duration or frequent reselection, to reduce power consumption during unnecessary network reselection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal device performs network reselection according to network parameters, then network connection quality is improved, but power consumption increases due to repeated reselection reporting

Engineering Contradiction:
Improvenetwork connection qualityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The terminal device monitors reselection information and detects when Ping-Pong reselection occurs between cells. Based on this feedback, the device intelligently adjusts its behavior by suspending reselection reporting when the same source and target cells are detected in sequential reselection events, thereby reducing unnecessary power consumption while maintaining network connection quality.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The terminal device autonomously identifies and handles Ping-Pong reselection scenarios without requiring network-side intervention or parameter adjustments. By self-detecting the reselection pattern and self-regulating the reporting behavior, the device resolves the power consumption issue independently, eliminating the need for costly network parameter modifications.

Inventive Principle:
Principle #25Self-service

2Use of energy by moving object

If network parameter configuration is adjusted to avoid over cell reselection, then power consumption is reduced, but implementation cost and difficulty increase

Engineering Contradiction:
Improvepower consumptionVSAvoidimplementation ease
Core Design Contradiction:
Use of energy by moving objectVSEase of manufacture

Solution Approach 1:

Instead of modifying network-side parameters to prevent over cell reselection (traditional approach), the invention inverts the solution by keeping network parameters unchanged and implementing the intelligence at the terminal device side. The terminal autonomously detects and handles Ping-Pong reselection, shifting the problem-solving responsibility from network operators to end devices, thereby simplifying implementation.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The solution uses lightweight software-based detection and control mechanisms at the terminal device rather than expensive network infrastructure modifications. The approach relies on simple algorithms that monitor reselection patterns and suspend reporting temporarily when needed, providing a cost-effective alternative to network parameter reconfiguration.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

Aspects of the present disclosure relate to a control method for reporting information, a control device for reporting information, and a storage medium. The method can include recording, in response to an action of network reselection of a terminal device, reselection information of the network reselection, and determining whether the reselection information meets a preset condition, and disabling the function of the terminal device to report the reselection information if it is determined that the reselection information meets the preset condition. In this way, the power consumption caused by the reporting of the reselection information when the terminal device performs over network reselection may be prevented, thereby saving the power of the battery of the terminal device.
