It is about.

Conventional broadcasting systems are generally television systems that emphasize visual and auditory effects, and radio systems that emphasize auditory effects.

However, with the development of communication technology, portable terminals (eg, mobile communication terminals, PDAs, notebook computers, etc.) have been developed to enable users to use communication services without being restricted by place or time.

In addition, since such a portable terminal includes a function of wirelessly transmitting and receiving data such as letters, numbers, and graphics, general information such as broadcasting service, credit card payment service, traffic information, and stock information may be used by using such communication function. It is used for a search service.

The conventional method for providing a broadcast service using such a portable terminal transmits (broadcasts) a message in a wireless network and allows a desired subscriber (or subscribers of the service) of all subscribers to simultaneously receive the message. In this way, the broadcast service method using a short message service.

That is, the mobile terminal receives the message of the service requested by the subscriber while sensing the broadcast cycle, and displays the received short message in a text format on the display unit of the portable terminal. Of course, even if the portable terminal does not receive the broadcast short message by detecting the broadcast period, a method of transmitting a broadcast short message from the server to the portable terminal in the form of a push service may be applied.

The broadcast short message may include information for a broadcast service (for example, breaking news, weather, stock market conditions, etc.) and a text message containing contents of an advertisement.

However, the conventional broadcast short message may provide important information to the subscriber, but is limited to a text service, and thus there is a limit in that it cannot provide various services that can be provided by the broadcast service.

In addition, in the conventional broadcast type short message, the type of information to be configured is limited to text, so that the subscriber can check what the information means only after confirming all the information displayed on the display unit.

Accordingly, an object of the present invention is to provide an object type graphic data transmission system and method using a broadcast service that can provide various services that can be provided by a broadcast type service using a broadcast type short message including graphic data as well as text data. It is.

It is another object of the present invention to include graphic data in a broadcast type short message displayed on a display of a user terminal, so that the subscriber can recognize the general contents of the broadcast data only by the displayed graphic data. It is to provide a data transmission system and method.

Still another object of the present invention is to transmit different graphic data for each broadcast cycle, thereby enabling periodic upgrade of the standby screen display, and transmitting object-type graphic data using a broadcast service that may induce user's curiosity according to a screen change. It is to provide a system and method.

Still another object of the present invention is an object type graphic using a broadcast service capable of minimizing the communication burden when the broadcast short message is transmitted to a plurality of user terminals even if the text message includes graphic data as well as text data. It is to provide a data transmission system and method.

However, in the following description of the present invention, for convenience of understanding, a user terminal is described as a mobile communication terminal, an external system is a mobile communication service system, and broadcasting data is transmitted in the form of a short message. do.

In addition, in describing the present invention, in order to facilitate the overall understanding, the same reference numerals will be used for the same means regardless of the reference numerals.

1 is a schematic overall configuration diagram of an object-type graphic data transmission system using a broadcast service according to the present invention.

That is, FIG. 1 illustrates that an information provider moves by inputting broadcast data and receiver information (eg, a phone number) using a user terminal (eg, a personal computer, a mobile terminal, a PDA, etc.) coupled with a communication network. When transmitting to the communication service system 120, the mobile communication service system 120 receives the broadcast data and receiver information, and transmits the received broadcast data to the mobile communication terminal 130 corresponding to the receiver information This is the drawing.

In addition, the present invention is to produce the broadcast data itself in the mobile communication service system 120, or convert the broadcast information provided from the information provider to the broadcast data according to the present invention to transmit to the mobile communication terminal 130, or The same may be applied to the case where the broadcast data is searched for itself and transmitted to the mobile communication terminal 130, which will be described later with reference to the flowchart of FIG. 3.

Referring to FIG. 1, an object type graphic data transmission system using a broadcast service according to the present invention may include an information provider terminal 110, a mobile communication service system 120, a user terminal 130, and the like.

The mobile communication service system 120 includes an inter-working function (IWF) 142, a short message service center (SMSC) 144, and a mobile switching center (MSC) 146. Visitor Location Resister (VLR) (148), Home Location Resistor (HLR) 150, Base Station Controller (BSC) 152, Base Transceiver Station (BTS) 154, and the like.

Since the network interworking device (IWF) 142 has a modem and a PPP server function, data transmission and reception using a mobile communication terminal can be performed using only a mobile communication terminal without a separate wireless modem, as well as a mobile communication terminal. An apparatus that enables connection between the Internet and a PC communication network enables a connection between the information provider terminal 110 and the short message service center (SMSC) 144.

The information provider transmits the broadcast message and the receiver information to the mobile communication service system 120 through the communication network using the information provider terminal 110 combined with the communication network.

In this case, the broadcast message transmitted to the mobile communication service system 120 through the communication network includes text data and graphic data, and the graphic data is composed of code graphic data in a text format rather than a conventional bitmap type. This will be described later in detail with reference to the accompanying drawings.

The short message service center (SMSC) 144 transmits the broadcast message and the receiver information received from the information provider terminal 110 to the exchange (MSC) 146.

The exchanger (MSC) 146 uses the visitor location register (VLR) 148 and the home location register 150 to determine the location of the mobile communication terminal 130 to which the broadcast message should be sent, and to the mobile communication. The broadcast message is transmitted to a base station (BTS) 154 suitable for transmitting the broadcast message to the terminal 130.

The exchange (MSC) 146 is a transport protocol processing function for a short service, a representative number identification and access function of a short message service center (SMSC) 144, and a short message service center (SMSC) from a public switched telecommunication network (PSTN) ( Relay call processing and trunk access to 144).

The visitor location register (VLR) 148 performs a short message subscriber authentication function, an information search function for a short service subscriber when a short message is sent and received, and a location registration function of a call subscriber who is not registered.

The home location register (HLR) 150 performs a function of recording and storing information of a subscriber located in a mobile communication service subscriber living area.

Subsequently, the base station (BTS) 154 transmits the broadcast message received from the switching center (MSC) 146 to the mobile communication terminal 130 corresponding to the receiver information under the control of the base station controller (BSC) 152. .

The base station controller (BSC) 152 manages eight or more base stations (BTS) 154, and when the call between the mobile communication terminal 130, 64kbps voice PCM signal using the IS-96 voice compression algorithm, 8kbps or less To perform the function of compression.

In addition, the base station (BTS) 154 supports a short transmission / reception function through an access / paging channel, a short transmission / reception function through a traffic channel, a format conversion / reverse conversion of a data burst message into a short message, and a service option processing function. Perform.

2 is a schematic configuration diagram of a user terminal applicable to an object type graphic data transmission system using a broadcast service according to the present invention.

2, the user terminal 130 according to the present invention may include a transceiver 202, a controller 204, a storage 206, a data processor 208, and a display 210.

The transceiver 202 performs a function of receiving broadcast data including text data and graphic data from an external system (eg, the mobile communication service system 130, etc.).

The controller 204 controls and manages each means included in the user terminal 130 so that the broadcasting data received through the transceiver 202 can be displayed on the display 220.

The storage unit 206 is means for accumulating the broadcasting data received through the transmission / reception unit 202 under the control of the control unit 114 when a user's request is input.

The data processor 208 converts broadcast data received through the transceiver 202 or broadcast data accumulated in the storage 206 into a graphic format that can be displayed on the display unit 220 under the control of the controller 204. It performs the function.

The graphic data included in the broadcasting data according to the present invention includes code graphic data in which information such as color, size, and position of a graphic to be displayed through the display unit 120 is described in text format. Of course, the text data included in the broadcast data may also be converted to code text data in a text format.

That is, the data processing unit 208 according to the present invention interprets broadcast data including code graphic data through a predetermined method and converts the data into a graphic format that can be displayed on the display unit 210 in the user terminal 130. To perform the function.

Of course, the data processing unit 208 is not configured as a separate means of hardware, but the data processing unit 208 is configured separately by upgrading a program included in a conventional user terminal (mobile communication terminal, PDA, notebook computer, etc.) It is also possible to expect the same effect as. Therefore, the user terminal 130 according to the present invention is not limited to the type or type as described above can be easily applied.

The display unit 220 displays a graphic corresponding to the graphic format converted by the data processing unit 208 under the control of the control unit 204 and performs a function of allowing the user to visually check.

3 is a flowchart illustrating a method for transmitting object type graphic data using a broadcast service according to the present invention, and FIG. 4 is for broadcasting when a broadcast message is transmitted using an object type graphic data transmission method using a broadcast service according to the present invention. A diagram illustrating the format of a message.

That is, FIG. 3 shows the broadcast data produced by the mobile communication service system 120 by itself, or converts the broadcast information provided from the information provider into broadcast data according to the present invention and transmits the broadcast data to the mobile communication terminal 130 or externally. FIG. 1 is a flowchart illustrating a method of converting graphic data into code graphic data according to the present invention and transmitting the graphic data when the graphic data is included in the case where the broadcast data is searched for itself and transmitted to the mobile communication terminal 130.

In order to facilitate understanding of the object-type graphic data transmission method using the broadcast service according to the present invention shown in FIG. 3, the broadcast format shown in FIG. 4 will be described together.

In addition, referring to FIG. 3, in describing an object type graphic data transmission method using a broadcast service, a subject performing a broadcast service is actually a short message service center (SMSC) 130 in the mobile communication service system 120 or separately. Although it may be a broadcast system (not shown) of the mobile communication service system 120 will be described collectively.

Referring to FIG. 3, in step 310, the mobile communication service system 120 transmits broadcast information (eg, weather information, campaign information, stock market status, etc.) to be transmitted to the mobile communication terminal 130 through various methods described above. Collect it.

In operation 315, the mobile communication service system 120 determines whether graphic data is included in broadcast information collected through operation 310.

Referring to FIG. 4, assuming that broadcast information to be currently performed in the mobile communication service system 120 is campaign information on safe driving, text data “safe driving” and graphic data symbolizing a traffic light are shown at 410. In this case, the inspection result that the graphic data is included through the inspection of step 315 will be derived.

Referring back to FIG. 3, if the graphic data is included as a result of the check in step 315, the process proceeds to step 320; otherwise, the process proceeds to step 335.

In operation 320, the mobile communication service system 120 may display basic graphics (for example, dots, lines, faces, and rectangles) that may display graphic data included in the broadcast information collected through operation 310 in the mobile communication terminal 130. , Triangles, circles, ellipses, etc.) and text data.

Of course, the step of separating the graphic data in step 320 is not physically or physically separating or dividing the graphic data, but detecting the outline of each area constituting the graphic data to extract only relevant information. Of course, it can be made.

Referring again to FIG. 4, graphical data after separation through step 320 is shown at 420.

That is, in the case of transmitting the text data 'safe driving' shown in 410 and the graphic data symbolizing the traffic light to the mobile communication terminal 130, when the present invention is applied, the squares 421 and 422 having two different sizes, Only three circles 423, 424 and 425 having the same size but different display positions and text data 426 of 'safe driving' need only be transmitted to the user terminal.

Referring back to FIG. 3, in step 325, the mobile communication service system 120 converts each of the components separated in step 320 into code graphic data in a text format.

Hereinafter, a case of converting each component into code graphic data in a text format will be described using the format of the broadcast message shown in FIG. 4.

The format of the code graphic data applied to the present invention is not limited to a specific communication protocol, and may be appropriately converted and applied to various communication protocols simultaneously, but here, NAPLPS (North American Presentation Level Protocol Syntax) is used as a format of code graphic data. The following description will focus on the case where the communication protocol is applied.

NAPLPS (North American Presentation Level Protocol Syntax) is a North American Presentation Level Protocol protocol syntax. It is one of the international standards used to transmit videotex screen information in North America, including the United States and Canada. Based on Teldidon.

Teldidon is Videotex's information transfer method, and picture information uses the alphageometric method to display the figure by a predetermined Picture Description Instruction (PDI) command of the image representation. The same geometric figures are combined and represented, and character information is transmitted using codes.

As shown in FIG. 4, when the graphic data “safe driving” and the graphic data in the form of a traffic light are simultaneously transmitted, the code graphic data supports an ASCII code as a text format code, and thus a format such as 430 may be applied.

In the code graphic data format of 430, C-Set1 and C-Set2 control each G-Set, and which graphic set is selected by the C-Set. That is, graphic data and text data are determined by which G-Set is selected by C-Set. If G-set is selected as text (ASCII), it can be used to define characters. It can be used to define the type of and its color.

G-Set1 and G-Set2 are graphic sets and have not only text but also PDI (Picture Description Instruction), that is, a command to draw a figure and its values. In addition, the present invention may further include a supplementary set (eg, a highlighted character, a symbol, etc.), a mosaic set, a macro set, a macro set, a dynamically redefinable character set, and the like. .

Hereinafter, in the format illustrated in FIG. 430, the configuration of an instruction or the like included in graphic data or the like will be defined to be, for example, a combination of an instruction code and an instruction execution information code. However, it is a matter of course that the configuration of graphic data can be variously applied according to a method defined by an administrator.

The graphic data in the shape of a traffic light and the text 'safe driving' shown in 410 may be divided into the graphic graphic and the safe driving data shown in 420. And a method for generating broadcast data including text data called 'safe operation'.

First, if you select the PDI G-set in C-Set1 to send the graphic graphics, G-set1 can now work using various commands such as color selection, shape selection, position selection, and line drawing.

First, in order to transmit the figure 421, if the color is selected as black, the position where the figure is drawn is selected, and the form is to send text data called a rectangle, the respective data is, for example, '3F 00 24'. 64 7C 6E 31 64 5E 67 '.

'3F' is data for determining color (Set Color) and recognizing the following code as color information, and '00' is data indicating that the color of the figure is black.

In addition, '24' is a code to designate the position of the starting point (Point Set Absolute), and the following code is recognized as a starting point, and '64 7C 6E 'is a code to designate the positions of x = 30 and y = 38. .

In addition, '31' is a code that creates a rectangle to the position specified in the following code and then fills the inside of the rectangle with the currently selected color (ie, black). '64, 5E, 67 'is dx (30), As a value of dy (50), this code is used to determine the width and height at the current position.

A graphic corresponding to 421 may be displayed using the above-described code data.

Similarly, when the figure corresponding to 422 is displayed, the respective data may be applied as, for example, '24 64 69 40 31 64 4B 55 '.

The difference from displaying 421 above is that there is no color determination code for the figure of 422. However, this is omitted since the same color as the color of 421 is applied to 422, and of course, the display may be repeatedly displayed in the same format without being omitted.

'24' is a code to designate the starting point of the position where the figure is displayed (Point Set Absolute), and recognizes the following code as the starting point, and '64 69 40 'designates the position of x = 40 and y = 8. This is the code.

In addition, '31' is a code that creates a rectangle to the position specified in the following code and then fills the inside of the rectangle with the current color (that is, black), and '64, 5E, 67 'is dx (10), As a value of dy (30), it is a code to determine the width and height at the current position.

A graphic corresponding to 422 may be displayed using the above-described code data.

In addition, when a figure corresponding to 423 is displayed in a similar manner, the respective data may be applied as, for example, '3F 52 2D 64 6E 40 64 49 52 64 62 40'.

'3F' is data for determining the color and recognizing the following code as color information, and '52' is data for indicating that the color of the figure is green.

In addition, '2D' is a code that displays a circle and fills the inside of the figure with the currently selected color, and the following code is used for the information of the starting point, the middle point, and the end point needed to show the circle. To decide. Of course, in this case, if the start point and the end point become the same point, it is possible to have the diameter values of the midpoint and the circle.

In addition, '64 6E 40 'is a code for designating a starting point, indicating position information of x = 40 and y = 48, and '64 49 52' indicates that each of the diameters is 10 with respect to the x and y axes, and '64 6E 40 'is a code for specifying an end point and indicates position information of x = 40 and y = 48. Therefore, the start point and the end point are the same to display a circular figure.

A graphic corresponding to 423 may be displayed using the above-described code data.

Similarly, when the figure corresponding to 424 is displayed, the respective data may be applied as, for example, '3F 76 2D 64 6F 47 64 49 52 64 6F 47'.

In most cases, it is the same as described above to display the figure corresponding to 423, so only other codes will be described to avoid duplication.

'76' means that the color of the figure is orange, and '64 6F 47 'designating a start point and an end point indicates position information of x = 40 and y = 63. In this case, since the starting point and the ending point are the same, the circular shape is displayed.

In addition, when the figure corresponding to 425 is displayed, the respective data may be applied as, for example, '3F 64 2D 65 69 46 64 49 52 65 69 46'.

As in the case of displaying 424, only the non-overlapping parts will be described. '64' means that the color of the figure is red, and '65 69 46 ', which specifies the start point and the end point, is x = 40, y. = 78 indicates location information. In this case, since the starting point and the ending point are the same, the circular shape is displayed.

Next, a method of displaying text data corresponding to 426 will be described.

Similarly to the method described above, if the text data corresponding to 426 is represented as code text data, the respective data may be applied as, for example, '24 6C 56 42 0F ESC 7E BC C8 C0 FC BF EE C0 FC '. .

'24' is the code to set the starting point position of the position where the text is displayed as before. The following code is recognized as the starting point. '6C 56 42' is the same as x = 80, y = 50. This code specifies the location.

Now we need to display the contents of the text data, but the contents of these text data are in another G-set, so we need to switch from the previously set PDI to ASCII. This is also done by activating ASCII on the G-set in the C-set.

'0F' is a code to select ASCII text to G-Set1, and 'ESC 7E' is a code to select G-set2 as ASCII when 8 bits.

'BCC8' is a code for displaying text data of 'in', 'C0FC' is a code for displaying text data of 'before', 'BFEE' is a code for displaying text data of 'luck', 'C0FC' is the code that displays the text data 'before'.

In this way, the broadcasting data can be displayed and the overall broadcasting data is' 3F 00 24 64 7C 6E 31 64 5E 67 24 64 69 40 31 64 4B 55 3F 52 2D 64 6E 40 64 49 52 64 6E 40 3F 76 2D 64 6F 47 64 49 52 64 6F 47 3F 64 2D 65 69 46 64 49 52 65 69 46 24 6C 56 42 0F ESC 7E BC C8 C0 FC BF EE C0 FC '.

Referring back to FIG. 3, in step 330, the mobile communication service system 120 determines whether the operation of converting graphic data into code graphic data is completed (ie, code graphic data generation completion) through steps 320 and 325. do.

If the generation of the code graphic data is completed through the inspection of step 330, the process proceeds to step 335, and the converted code graphic data is transmitted to the appropriate mobile communication terminal 130 through the communication network as a broadcast message; Proceed with the conversion to code graphic data.

FIG. 5 is a diagram illustrating a process until a broadcast message according to the object type graphic data transmission method using a broadcast service is actually generated in a mobile communication service system and displayed on a mobile communication terminal.

That is, FIG. 5 is a diagram provided to look at the matters described so far, and is illustrated on the assumption that the content of the broadcast information is a weather forecast.

Referring to FIG. 5, when the mobile communication service system 120 first collects broadcast information including text data of 'sunny weather today' and sun-shaped graphic data representing sunny weather, the broadcast information is first transmitted to the mobile communication service. The terminal 130 may be divided into basic figures (eg, points, lines, faces, squares, triangles, circles, ellipses, etc.) and text data that can be displayed on the terminal 130.

Then, the separated basic figure and text data are converted into code graphic data and code text data in a text format including information on the shape, color, and position of the figure.

Thereafter, the graphic data converted into code graphic data and the text data converted into code text data are converted into a broadcast data format, and then the converted broadcast data format is transmitted to the mobile communication terminal 130 through a communication network.

After receiving the broadcast data format from the mobile communication service system 120 through the communication network, the mobile communication terminal 130 displays graphic data in a form that can be displayed using text data and text data included in the broadcast data format. After interpreting the text data into the text data, the analyzed broadcast information is displayed on the display unit 210 of the mobile communication terminal 130.

In FIG. 5, the respective regions (eg, basic figures, text, etc.) constituting the graphic data and the text data are sequentially displayed on the display unit 210 of the mobile communication terminal 130. Preferably, the analysis may be displayed in one graphic form at a time after the analysis is completed.

6 is an exemplary view of a screen display to which the object-type graphic data transmission method using a broadcast service according to another embodiment of the present invention is applied.

The mobile communication terminal 130 currently possessed by the majority of users has a function of modifying or changing a standby screen, a ringtone, and the like to suit a user's intention or taste.

Accordingly, many users may access a web server that performs a data providing service such as a standby screen, a ringtone, or the like through a communication network, and then download a desired animation or ringtone to the mobile communication terminal 130 to change a setting.

However, in order to use a download service such as an animation or a ringtone, the corresponding user must pay a predetermined fee, and there is a limit in that the standby screen cannot be changed more times because of such a charge.

However, according to the present invention, graphic data and / or text data received through a communication network can be automatically set as an image to be applied to a standby screen. In addition, in this case, it is a matter of course that the user's mode selection (for example, the automatic standby screen change mode) can be preceded.

FIG. 6 illustrates that broadcast data (ie, graphic data and text data) for weather forecast is received to a user terminal at a predetermined time, and the received graphic data and text data are automatically generated as an image for a standby screen of the mobile communication terminal 130. It is an example of the screen display which shows the process of setting and converting.

Referring to FIG. 6, an initial standby screen image of the mobile communication terminal 130 may include a date (eg, 4/24), a day of the week (eg, (month)), and time data (eg, 5: In the case of the default standby screen providing only 47 pm), the text data 'Sunday Sunny' and the graphic data of the sun are presented at 5:50 at 5:50, and at 5:53 The text data 'Tomorrow is rain' and graphic data in the form of dark clouds and rain are presented on the standby screen.

That is, this case illustrates an example in which broadcasting data is received every predetermined time (for example, three minutes), and the received broadcasting data is automatically set and converted into a standby screen.

In addition, the time interval during which the broadcast data is received may be applied differently, and the same image is not continuously presented to the standby screen for a predetermined time, and when the next broadcast data is received after receiving several broadcast data at the same time. As a matter of course, the standby screen may be presented in a constantly changing form at a predetermined time (for example, 1 second).

However, since the process of displaying the broadcast data on the display unit 210 of the mobile communication terminal 130 has been described above, a description thereof will be omitted here, and the method of setting the image data to the standby screen has a general knowledge in the same field. As it is general technical knowledge to the user, the description thereof will be omitted.

The present invention is not limited to the above embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.

As described above, the present invention can provide various services that can be provided by a broadcast type service using a broadcast type short message including graphic data as well as text data.

In addition, the present invention includes the graphic data in the broadcast type short message displayed on the user terminal display, so that the subscriber can recognize the general contents of the broadcast data only by the displayed graphic data.

In addition, the present invention can minimize the communication burden when the broadcast short message is transmitted to the plurality of user terminals even if the short text message includes graphic data as well as text data.

In addition, since the present invention can transmit different graphic data for each cycle of the broadcast, it is possible to periodically upgrade the display of the standby screen, and may induce user's curiosity according to the screen change.
