RF-ID Tag Based Mobile Internet Access via Reader Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile stations require users to manually type URLs for internet access, which is inconvenient, and the integration of RF-ID readers increases device costs.
Innovation Solution
An RF-ID reader and local site server system that reads an RF-ID tag value from a mobile station, transmits it to a provider server to obtain an IP address, and provides a corresponding URL for internet access without manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an RF-ID reader is installed in the portable device to enable automatic URL access, then the convenience of operation is improved, but the device cost increases
Solution Approach 1:
The patent extracts the RF-ID reader function from the mobile station and relocates it to a separate URL providing apparatus (such as a PC or fixed terminal). The mobile station only needs to contain an RF-ID tag, which is much cheaper. This separation allows the mobile station to gain automatic URL access capability without bearing the high cost of an RF-ID reader, thus resolving the contradiction between operational convenience and device cost.
Solution Approach 2:
The patent introduces a URL providing apparatus as an intermediary between the RF-ID tag and the internet access function. This intermediary contains the expensive RF-ID reader and handles the URL provision, while the mobile station with the cheap RF-ID tag receives the URL through communication protocols. This intermediary structure enables the mobile station to benefit from automatic URL access without directly incurring the high hardware cost.
2Device complexity
If a manual input method is used for URL entry in conventional mobile stations, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The patent implements a self-service mechanism where the mobile station automatically obtains URLs by presenting its RF-ID tag to the URL providing apparatus. The system automatically performs the URL lookup and provision processes without requiring manual typing or complex input operations. This maintains the simplicity of the mobile station's input interface while dramatically improving operational convenience through automatic URL acquisition.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and cost-effective internet access for mobile stations by eliminating the need for manual URL input and reducing device costs through the use of an RF-ID tag instead of a reader.
Implementation Method 1
a terminal reads an RF-ID tag value attached to a movie poster or a traffic display

AI summary
The present invention relates to a URL providing apparatus and a method thereof, and a mobile station that accesses the Internet by using the provided URL, and an Internet access method thereof. The mobile station attaches an RF-ID tag that stores an RF-ID tag value corresponding to identification information of the mobile station thereto, and thus when a user brings the mobile station into an interrogation range of an RF-ID reader included in the URL providing apparatus, the URL providing apparatus receives the corresponding RF-ID tag value from the RF-ID reader. When the URL providing apparatus acquires an IP address of the mobile station by using the received RF-ID tag value and provides a URL to the mobile station by using the acquired IP address, the mobile station automatically accesses the Internet by using the URL. Such an Internet access method can minimize additional cost of the mobile station and simplify an Internet access process to a specific URL.
