Solution Overview

Problem

Current communication systems face increased traffic load due to frequent transmission of location information from terminal devices, which can adversely affect intrinsic communication quality and data size.

Innovation Solution

A terminal device and base station system that dynamically adjusts the threshold for location information transmission based on measured traffic, where the terminal device only transmits new location information if the calculated distance of travel exceeds a threshold value determined by the base station, thereby reducing unnecessary data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If location information is transmitted frequently to ensure service quality, then service quality is improved, but traffic load increases

Engineering Contradiction:

Improveservice qualityVSAvoidtraffic load

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies dynamics by making the transmission threshold adjustable based on traffic conditions. The base station dynamically sets the threshold value according to current traffic load, allowing the system to adapt between frequent transmission (for service quality) and infrequent transmission (for traffic reduction) depending on real-time conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of transmission threshold based on traffic load. When traffic is heavy, the threshold is increased to reduce transmissions; when traffic is light, the threshold is decreased to allow more frequent transmissions, thus balancing service quality and traffic load

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

If the transmission threshold is set low to reduce traffic, then traffic load is reduced, but service quality deteriorates

Engineering Contradiction:

Improvetraffic loadVSAvoidservice quality

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent implements feedback by having the base station monitor traffic load and adjust the transmission threshold accordingly. The base station provides feedback to the terminal about the appropriate threshold based on current network conditions, creating a closed-loop control system that balances traffic reduction with service quality maintenance

Inventive Principle:

Principle #23Feedback

3Ease of operation

If area information is transmitted to control transmission, then transmission control is improved, but data size increases

Engineering Contradiction:

Improvetransmission controlVSAvoiddata size

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential control parameter (threshold value) needed for transmission control, eliminating the need to transmit comprehensive area information. This reduces the data size while maintaining the core functionality of transmission control

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A retrieval unit retrieves location information. A storage stores location information transmitted from a transmitter. A derivation unit derives a distance of travel based on the location information stored in the storage and the location information newly retrieved by the retrieval unit. A controller causes the transmitter to transmit the location information newly retrieved by the retrieval unit, if the distance of travel exceeds a threshold value.
