Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The conventional 802.11u standard for updating advertisement information on user devices leads to unnecessary power consumption, increased load on advertisement servers, and delays due to periodic scans and requests for all advertisement data, even if only some information has changed.

Innovation Solution

A method and apparatus that determine the update time point for advertisement information by using update condition information, such as validity terms and location identification, allowing user devices to actively scan and request updates only when necessary, reducing power consumption and server load, and ensuring timely updates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the user device performs periodic AP scan process and advertisement service request process to update advertisement information, then the advertisement information can be kept updated, but the current consumption of the user device increases and the load on the advertisement server increases

Engineering Contradiction:

Improveadvertisement information update timelinessVSAvoidcurrent consumption of user device

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic advertisement information updates by having the user device perform AP scan and advertisement service request processes at predetermined intervals. The controller is configured to automatically trigger these update operations periodically, ensuring advertisement information remains current while managing power consumption through scheduled rather than continuous operations.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent employs feedback mechanisms where the user device receives advertisement information from the advertisement server and compares it with locally stored information. The device only initiates update requests when actual updates are detected, rather than continuously polling, thereby reducing unnecessary power consumption and server load while maintaining information freshness.

Inventive Principle:

Principle #23Feedback

2Reliability

Engineering Contradiction:

Improveadvertisement information update timelinessVSAvoidresponse time of advertisement server

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent implements partial action by having the user device request only specific advertisement information that has actually changed, rather than retrieving all advertisement data continuously. The controller compares received advertisement information with stored information and selectively updates only when changes are detected, reducing server processing load and improving response time while maintaining update timeliness.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If the user device cannot stay in sleep state to periodically perform AP scan process, then advertisement information can be updated regularly, but the usable time of portable device is reduced

Engineering Contradiction:

Improveadvertisement information update regularityVSAvoidusable time of portable device

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent schedules AP scan and advertisement service request operations to occur at predetermined intervals when the device is active, rather than requiring continuous operation. The controller manages power states by enabling periodic updates during usable time while allowing the device to enter sleep mode otherwise, thus maintaining update regularity while maximizing portable device usability.

Inventive Principle:

Principle #19Periodic action

4Adaptability or versatility

If multiple user devices transmit advertisement service request message to the advertisement server, then each device can receive advertisement information, but the response time becomes longer due to increased server load

Engineering Contradiction:

Improvenumber of supported user devicesVSAvoidresponse time of advertisement server

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent reduces server load by implementing selective information retrieval. Each user device receives and processes only the specific advertisement information that has been updated, rather than retrieving complete advertisement datasets. This partial action approach allows multiple devices to be supported simultaneously while maintaining faster response times by minimizing data transmission and processing volume.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

According to the present invention, a user device can obtain together, from an advertisement server for providing an advertisement service, via a neighbor access point device, update condition information on advertisement information in the course of obtaining the advertisement information. In addition, if the update condition information is satisfactory, the user device requests the advertisement information from the advertisement server via an AP and stores the advertisement information received in response to the request, thereby being capable of updating the advertisement information.
