The present invention relates to a location-based web content authoring method, a location-based web data service receiving device in a digital mobile terminal and a method thereof, and more particularly, to a speech-based web markup language such as VoiceXML markup language. Location-based web content, which enables location-based data services to be provided not only in graphic form but also in voice form, by adding location-related information to web information expressed in a markup language designed to express information in speech form. The present invention relates to an authoring method, a location-based data service receiving apparatus in a digital mobile receiving terminal, and a method thereof.

The BWS (Broadcasting Web Sites) service method, which is one of the conventional web data service providing methods, is used in DAB and DMB, and provides web-based data service to users by processing and transmitting web information using HTML markup language.

The BWS service provision method is based on HTML3.2, which has a relatively low complexity in terms of implementation in consideration of the performance of the receiver, and provides a web service by transmitting simple multimedia such as jpg and png together.

When providing a location-based web data service using the conventional method as described above, there is a problem that it is impossible to provide location information related to a corresponding content (that is, a service) by including it in the content. In order to solve this problem, some web data services support scripts, but this method also has a problem that cannot be allowed under the existing standard.

Therefore, there is an urgent need for a voice-based location-related data service that can overcome the above problems and integrate with existing graphic-based BWS services. If such a service is provided, it will be possible to provide location-related services both graphically and by voice. In addition, the user will be able to view or listen to the location-related service by accessing the service automatically or at the request of the user if the location-related service exists anywhere in the movement.

The present invention has been proposed to solve the above problems, and provides location-related information in web information expressed in a speech-based web markup language such as VoiceXML markup language (a markup language designed to express web information in a speech form). In addition, the present invention provides a location-based web content authoring method, a location-based web data service receiving device in a digital mobile terminal, and a method for providing a location-based data service in a graphic form as well as a voice form. The purpose is.

Other objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. It will also be appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

According to an aspect of the present invention, there is provided a method of authoring a location-based web content in a location-based web data server, the method comprising: authoring a speech web document associated with a location using a speech-based web markup language; And a tag combining step of adding a location information related tag in the authored location related voice web document.

On the other hand, the present invention, a location-based web data service receiving apparatus in a digital mobile receiving terminal, comprising: receiving means for receiving location-based web content embedded with location information; And a location-based web service driving platform for executing a web content related to the received location information to provide a web service in a voice or graphic form.

On the other hand, the present invention, a method for receiving a location-based web data service in a digital mobile terminal, comprising: a receiving step of receiving a location-based web content in which location information is inserted; And a location-based web service step of providing a web service in a voice or graphic form by executing web content related to the received location information.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, it is intended to specify a method and apparatus for integrated representation of location information for providing a web-based data service associated with a location in a voice form as well as a graphic form.

That is, in order to provide location-related web data services by integrating location information, which is impossible due to the limitations of the conventional technology described above, into a markup language capable of providing a web service in the form of voice, the following technical problem must be solved. do.

First, a clear definition of location information is needed. Here, the position information is actually information to be described in the content, which is information specifying an arbitrary region or coordinates defined by the service. This location information is required when matching with real-time location information updated in the actual terminal.

Second, it is required to associate the defined location information with the content. In general, the location information specified must be described somewhere along with the content being transmitted. In actual implementations, the location information must be linked in an efficient manner.

Third, the service should be provided to the user using location information. The service must be provided to the user automatically or on demand using the defined and associated location information.

Hereinafter, linkage between location information and contents, and a service providing method through the same will be described in detail.

First, location information will be described.

Today, location information is beyond the concept of simple location information, and its value as a base information that can provide useful information when it is guaranteed through various media and is related to other information is increasing.

Some mobile terminals (PDAs) are equipped with a GPS (Global Positioning System) receiver (receiving module) for receiving location information, and provide services using location information to a user in real time. As in the existing general local service environment or service environment such as mobile communication, the importance of location information is increasing in the digital broadcasting field, and various services applying the same are being studied.

In general, location information may be separated into latitude, longitude, and altitude, as shown in FIG. 1A. Such location information enables to acquire the location of the terminal, in particular, the location of the user, in real time through the GPS receiver, and the location information used in the present invention is as follows.

 ■ Regional Center Information: Latitude, Longitude, and Altitude

 ■ Area range information: latitude deviation, longitude deviation, and altitude deviation

When the location information is utilized in the digital mobile reception terminal, the location information may be associated with data transmitted through a broadcasting network, thereby providing an advantage of providing a data service related to location.

In one embodiment, the location information of a specific range may be imposed on the data content transmitted through the broadcasting network to provide relevant data only to users within the corresponding location range. It can be used for advertisements or to deliver a variety of other local information, including notifications for public purposes. More specifically, when used in an advertisement, special discount information of a certain department store may be automatically provided to users around the department store (ie, users located within a specific location range designated by the content).

In order to enable the above examples, a concept of a broader meaning that may have meaning in mobile reception must be considered, as illustrated in FIG. 1B, beyond the simple concept of location information. As shown in FIG. 1B, there is a transmission zone 121 covered by a broadcasting network, and the mobile zone may be divided into a cell zone 122 and a cell center point 123 that are arbitrarily divided.

The transmission zone 121 refers to a range of the transmission signal. For example, the transmission area may be a range identified and limited by transmitter indicator information (TII) in a DAB / DMB broadcasting system.

 In addition, the cell area 122 refers to a small area partitioned within the transmission area 121. In the example described above, the cell area may be around the department store. This may be a logically partitioned area, or it may be the area of the repeater to cover the transliteration area. Data designated to a particular cell area may be serviced only to users who are located or allowed in that cell area.

In addition, as shown in FIG. 1A, the cell range means a position within a constant deviation (ie, longitude deviation, latitude deviation, and altitude deviation) about the cell center point 101, and may normally overlap with another cell. Here, the cell center point represents the center position of each cell defined arbitrarily. In practice, the cell center point 123 becomes a base when setting the cell area 122 and the transmission area 121.

In order to actually service the location information defined as described above, it must be associated with the web content and the digital mobile terminal. This will be described in detail with reference to FIG. 3.

To this end, the present invention provides a method for integrating location information as described with reference to FIGS. 1A and 1B into VoiceXML, which is a web markup language that can transmit / receive voice and input / output through a broadcasting network. I will explain. In addition, the present invention also provides a method and apparatus for providing a location-based web data service by receiving the actual location information from the digital mobile terminal using the above method, which will be described with reference to FIGS. 3 and 4. do.

VoiceXML is a markup language that enables web input / output in the form of voice. When a browser capable of running an application is mounted on a digital mobile terminal, VoiceXML outputs web information to the user by voice and receives the information in voice form. Allows you to perform related browsing functions. VoiceXML is a type of eXtensible Markup Language (XML) that has the advantage of being able to easily extend other related elements, or tags, and easily integrate with other markup languages.

Therefore, basically, location information should be associated with at least one application (an application composed of a VoiceXML document) as one meta information. To do this, location information must be provided in the root document, the parent document of each application. Here, within one root document there must be one or more services, i.e. applications, associated with the location.

Therefore, in the present invention, in order to associate the location information with the content, the location information related tag (<location> tag) to be integrated together in VoiceXML is defined as shown in the following [Table 1].

[Table 1] illustrates only the latitude and longitude as the location information. The location information is not limited thereto, and altitude information may be included as necessary. In addition, the <location> tag of the illustrated table may be defined with any other name of any other form. In addition, in integrating the location-related tag into VoiceXML, a separate separate namespace may be designated to integrate with VoiceXML or the location-related tag may be extended to extend VoiceXML.

An embodiment of integrating location information with VoiceXML using the <location> tag is as follows.

<root>

<location id = "this_location" longitute = "+35.1" latitude = "+150.4" devlong = "+0.5" devlati = "+0.1" doc = "event_of_today.vxml">

</ root>

<vxml>

<script>

   <! [CDATA [

function getLocation ()

var location = new arrary ();

location [0] = GPS_getLongitute (). longitute;

location [1] = GPS_getLatitute (). latitute;

return (location);

</ script>

<script>

function matchedDocument ()

var nextdoc = "NULL";

var curr_location = getLocation ();

var doc_location = new array ();

doc_location [0] = document.getElementbyId ("this_location"). longitute;

doc_location [1] = document.getElementbyId ("this_location"). latitute;

doc_location [2] = document.getElementbyId ("this_location"). devlong;

doc_location [3] = document.getElementbyId ("this_location"). devlati;

if ((doc_location [2]> (abs (doc_location [0] -curr_location [0]))) && (doc_location [3]>

(abs (doc_location [1] -curr_location [1]))))

nextdoc = document.getElementbyId ("this_location"). doc;

nextdoc = getPreviousPage ();

return (nextdoc);
