Solution Overview

Problem

The increasing communication traffic between wireless communication apparatuses and information processing apparatuses due to the provision of various services necessitates a reduction in communication traffic by optimizing the updating frequency of information, particularly position information.

Innovation Solution

A method and system for controlling the updating of information in wireless communication apparatuses by categorizing information into static and dynamic types, where static information is updated less frequently and dynamic information is updated based on changes, using a processor to determine the update frequency and wirelessly communicating with other devices to manage and update this information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If information is updated frequently to maintain relevance, then information freshness is improved, but communication traffic increases

Engineering Contradiction:
Improveinformation freshnessVSAvoidcommunication traffic
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent segments map information into two distinct categories: static map information (basic map data, road structures) and dynamic map information (traffic conditions, weather, events). This segmentation allows differential updating strategies where static information is updated less frequently while dynamic information is updated more frequently, thereby reducing overall communication traffic while maintaining information freshness for critical dynamic elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic updating frequencies based on information type and change characteristics. Static map information undergoes infrequent updates, while dynamic map information is updated frequently or in real-time. The system dynamically adjusts update timing and frequency based on the specific characteristics of each information category, optimizing the balance between information freshness and communication traffic.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If all information is updated at the same frequency, then system simplicity is maintained, but information relevance deteriorates

Engineering Contradiction:
Improveupdating frequency managementVSAvoidinformation relevance
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent applies local quality by assigning different updating frequencies to different types of map information based on their specific characteristics. Static map information (road structures, basic geography) is updated at lower frequencies, while dynamic map information (traffic conditions, weather changes, events) is updated at higher frequencies. This localized differentiation of update strategies ensures each information type maintains appropriate relevance without requiring complex system-wide changes.

Inventive Principle:
Principle #3Local quality

3Loss of energy

If communication traffic is reduced by updating information less frequently, then resource consumption is improved, but information timeliness deteriorates

Engineering Contradiction:
Improvecommunication resource consumptionVSAvoidinformation timeliness
Core Design Contradiction:
Loss of energyVSLoss of information

Solution Approach 1:

The patent segments map information into static and dynamic categories, enabling selective updating. Static information is updated infrequently to conserve communication resources, while dynamic information is updated frequently to maintain timeliness. This segmentation resolves the contradiction by applying resource-efficient updating only where appropriate while maintaining timeliness for critical dynamic elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic updating frequencies that adapt to information characteristics. The system dynamically determines update timing based on whether information is static or dynamic, ensuring resource-efficient updates for stable information while maintaining timely updates for changing information, thus balancing resource consumption and information timeliness.

Inventive Principle:
Principle #15Dynamics

AI summary

Techniques for controlling updating of information stored on a device, the information including information of a first type and information of a second type. The techniques include determining, using at least one processor, when a first item of information of the first type and a second item of information of the second type are to be updated, wherein the second item of information is to be updated more frequently than the first item of information; and causing the device to update the first and second items of information in accordance with the determination at least in part by wirelessly communicating with at least one other device.
