Solution Overview

Problem

Current wireless communications networks face challenges in efficiently managing and transmitting ancillary information, such as measurement data, from low-complexity devices like NB-IoT devices, which require minimal battery consumption and bandwidth usage, especially in scenarios where security and data size vary.

Innovation Solution

A terminal device with storage for ancillary information and a controller to determine the appropriate transmission method based on data size and network congestion, using random access preambles and plane solutions to selectively transmit data via control or user planes, ensuring efficient bandwidth use and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ancillary information is transmitted frequently to ensure network optimization, then network performance is improved, but device battery consumption increases

Engineering Contradiction:

Improvenetwork performanceVSAvoiddevice battery consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The terminal device stores ancillary information locally before network transmission is needed. By preparing measurement data in advance and keeping it ready in storage, the device can quickly transmit pre-measured data when the network requests it, avoiding the need for continuous active measurement and transmission cycles that would drain battery power.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts only the essential ancillary information that is actually needed by the network from the total possible data set. The network can request specific types of measurement data, and the terminal device transmits only those particular pieces of information rather than continuously transmitting all available ancillary data, reducing unnecessary energy consumption.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If all ancillary information is transmitted to ensure complete network optimization, then network optimization is improved, but bandwidth usage increases

Engineering Contradiction:

Improvenetwork optimizationVSAvoidbandwidth usage

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The network extracts and requests only the specific ancillary information subsets that are actually needed for current optimization tasks. Instead of the terminal device transmitting all stored ancillary data continuously, the network selectively requests particular measurement data types, reducing overall bandwidth consumption while maintaining effective network optimization.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system implements partial transmission of ancillary information based on network needs. Rather than transmitting complete datasets unnecessarily, the network requests and receives only the partial amount of ancillary data that is sufficient for current optimization requirements, avoiding excessive bandwidth usage.

Inventive Principle:

Principle #16Partial or excessive action

3Use of energy by moving object

If ancillary information is stored for extended periods to reduce transmission frequency, then battery consumption is reduced, but data relevance may deteriorate

Engineering Contradiction:

Improvebattery consumptionVSAvoiddata relevance

Core Design Contradiction:

Use of energy by moving objectVSLoss of information

Solution Approach 1:

The network provides feedback to the terminal device about which ancillary information is currently needed and how recent it should be. Based on this feedback, the terminal device can determine whether to transmit previously stored data or perform new measurements, balancing data freshness with energy conservation by only updating measurements when the network indicates current data may be outdated.

Inventive Principle:

Principle #23Feedback

4Quantity of substance

If different transmission methods are used for different data sizes to optimize efficiency, then bandwidth usage is optimized, but device complexity increases

Engineering Contradiction:

Improvebandwidth usageVSAvoiddevice complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The terminal device dynamically selects transmission methods based on current data characteristics and network conditions. When ancillary information data size is small, the device uses efficient control plane transmission; when data size becomes large, it switches to user plane transmission. This dynamic adaptation allows the device to optimize bandwidth usage for different scenarios without requiring permanently complex transmission capabilities.

Inventive Principle:

Principle #15Dynamics
