Description

METHOD AND SYSTEM FOR PROVIDING CALL SERVICE USING TAG}

The present invention relates to a method and a system for providing a call service using a tag, and more particularly, to a method and an apparatus for providing a call service using a tag of a hyper text markup language (HTML). It is about.

In general, a separate dedicated terminal for a call is required for a voice (video) call with the other party. Recently, research to replace such a dedicated terminal has been actively conducted.

This feature, which eliminates the need for a dedicated terminal for calls, can be implemented with software that can run on a universal terminal such as a PC, smartphone, or laptop, when installing client applications, or using RIA (Rich Internet Application) web-based applications. There is a way to implement this with simple URL access using technology.

Among the latter, the latter is evaluated as a more convenient technology in general because of its simple usage without the need for installing a separate application.

However, this is hardly a call feature that does not require a separate application. The reason is that the call function on the web is mostly implemented using RIA such as Adobe's Flash / FLEX, and it does not need to install a separate application. Flash is often used, so users have installed this plug-in in the past for their convenience.

Currently, the vast majority of PCs with flash plug-ins installed around the world feel that users are actually using the call without any additional installation.

Meanwhile, Korean Patent No. 393,364 (voice and video communication system on a web browser using the session initiation protocol) embeds a Session Initiation Protocol (SIP), which is a part of VoIP technology, into a web browser to display voice and video on a web browser. Disclosed is a technique for enabling communication at the same time.

However, in order to enable the above communication, a user agent client (UAC) must be installed on the client and a user agent server (UAS) on the server, respectively, and the user selects a link provided by the UAC. Communication with the other party of the server where Agent Server is installed is possible.

That is, the above-described technology also has a limitation in that a call can be made only when UAC and UAS are installed in a universal terminal such as a PC.

Thus, universal users without installing a separate software (application) (even if the software (application) that needs to be installed is paid) and without being affected by the terminal's environment (mobile, laptop or PC, etc.) There is a demand for a technology that allows a terminal to freely talk with the other party.

In order to solve the above problems of the prior art, the present invention is not affected by the installation of a separate software (application) or the environment of the terminal, and makes a voice (video) call with the other party using a tag mounted in all web browsers. to provide.

The objects of the present invention are not limited to the above-mentioned objects, and other objects not mentioned can be clearly understood from the following description.

In order to achieve the above object, a system for providing a call service using a tag according to an aspect of the present invention checks whether a telephone number is included in a string entered in a URL input window of a web browser, and provides the call service. A Domain Name Service (DNS) server that transmits an IP address of a web page to the web browser, and receives a request for transmission of a web page corresponding to the IP address from the web browser, and corresponds to the IP address. A web server for transmitting a web page to the web browser and a call request from the web browser to the telephone number are received, and the call request is sent to a Session Initiation Protocol (SIP) or a real-time transmission protocol ( Session Initiation Protocol (SIP) that converts to Real-time Transport Protocol (RTP) ) Includes a gateway.

In order to achieve the above object, a method for providing a call service using a tag of a web browser according to an aspect of the present invention (a) receiving a string including a phone number entered in the URL input window of the web browser; (B) extracting a telephone number from the received string, searching for an IP address of a web page providing the call service, and transmitting the extracted telephone number to the web browser together with the extracted telephone number; and (c) the web. Receiving a request for access to a web page corresponding to the extracted telephone number and the IP address from a browser, and requesting a call to the extracted telephone number.
