Web service delivery system based on device time zone location determination

Abstract

This invention discloses a web service provision system based on device timezone location determination. By loading an application and entering a web platform, the timezone capture module retrieves the device's timezone data and compares it with the timezone identifier and country code in a timezone-metadata lookup table to determine the device's country of origin. This allows the product display module to be switched to the language version compatible with the user's device. Simultaneously, after obtaining the original currency and price information of the products, the currency conversion module determines the country currency code used by the device based on the device's timezone data. It then performs price conversion using an exchange rate table and displays the result in the product display module, thus providing a web service more aligned with the user's national context.

Claims

1. A web service provisioning system for determining location based on device timezone, comprising: a client device loading an application, the client device having a central processing module, which is connected to a timezone acquisition module, a timezone-country mapping module, and a currency conversion module within the application, the currency conversion module being able to access or create an exchange rate table; the timezone acquisition module being used to acquire device timezone data of the client device, the device timezone data being sent to the timezone-country mapping module based on the processing logic of the web service, and accessing and comparing a built-in or pre-loaded timezone-metadata mapping table to obtain a country location; the device timezone data can also be sent to the currency conversion module, and being compared and compared in the timezone-metadata mapping table to determine a country currency code based on the device timezone data; A web platform, linked to the application, has a product display module for displaying the original currency and price information of a product; and a currency conversion module obtains the original currency and price information of the product from the product display module, uses the country currency code that matches the user's terminal device as a target currency, and then performs price conversion according to the exchange rate table to present the current price information in the product display module.

2. The web service provision system for determining location based on device time zone as described in claim 1, wherein, The application has a language switching module that uses a country code corresponding to the country's location as the query key and compares it with a country's language version in the time zone-metadata lookup table. If the comparison matches, it outputs the current language version as the text and page content in the product display module.

3. The web service provision system for determining location based on device time zone as described in claim 1, wherein, The time zone-metadata lookup table uses a time zone dataset (IANA Time Zone Dataset) and a country metadata dataset that are linked to the application as its data sources.

4. The web service provision system for determining location based on device time zone as described in claim 1, wherein, This time zone-metadata lookup table contains one of the following: a time zone identifier, a country code, and country metadata.

5. The web service provision system for determining location based on device time zone as described in claim 4, wherein, The country location corresponds to the country code, which covers all 418 IANA standard time zones and can be encoded in ISO 3166-1 alpha-2.

6. The web service provision system for determining location based on device time zone as described in claim 1, wherein, The time zone-metadata lookup table and the exchange rate lookup table can be static data directly embedded in a web page code or a front-end script.

7. The web service provision system for determining location based on device time zone as described in claim 6, wherein, The time zone-metadata lookup table and the exchange rate lookup table can be stored in a backend data service or queried by the application.

8. The web service provision system for determining location based on device time zone as described in claim 1, wherein, The device's time zone data is an operating system time zone, which can be presented in a format that varies depending on the operating system, browser version, or user environment settings. This format can be any one of an IANA time zone string, a UTC offset, and a simplified code.

9. The web service provisioning system for determining location based on device time zone as described in claim 8, wherein, The device's time zone information is a unique identifier conforming to the IANA time zone standard.

10. The web service provisioning system for determining location based on device time zone as described in claim 1, wherein, The currency conversion module uses the US dollar (USD) as the intermediary exchange rate and rounds to two decimal places to convert the price information of the product into the current price information, which includes a current currency and a current price figure.
