The present invention relates to a method for providing location information service using a set-top box combined with a digital television, a system for implementing the same, an information providing server, and a mobile terminal.

Broadcast receivers, or digital TVs (DTVs), are defined as devices that allow users to view or experience digital content through TV receivers. Commercially available digital TVs are integrated digital TVs that can digitally process data such as video and audio, and then transmit and display them on the screen using a digital transmission method without a separate digital set-top box (STB). There is a digital ready TV (Upgradable DTV, DTV Monitor) that does not include (DTV set, Integrated DTV) and digital tuner and decoder so that digital signal can be realized only when connected to an external set-top box.

The main advantage of such a digital TV is that it provides a higher quality of service than conventional analog TV. While the horizontal resolution of an existing analog TV using 525 horizontal scanning lines is about 330 lines, the HD-level horizontal resolution reaches 700 lines, providing more than 5 times clearer image quality. When adopting a plasma display panel (PDP) or a liquid crystal (LCD) instead of a conventional color CRT (CRT), it is possible to obtain a clean image of the same level as a PC in receiving an additional service according to digital broadcasting, that is, data broadcasting. In terms of sound quality, it provides excellent CD quality sound. Whereas conventional analog TVs provide two channels of stereo sound, digital TVs using Dolby AC3 and MPEG-2 Audio technology provide 5.1 channels of stereo sound that can be enjoyed in theaters. In aspect ratio, analog TV's aspect ratio is 4: 3, while digital TV is based on the ratio of 16: 9 that humans can visually feel stereoscopic and realistic.

Also, the most innovative feature of digital TV is the multimedia function provided by digital TV. A variety of two-way value-added services are available, including the Electronic Program Guide and the Internet, as well as searching for data while watching a program.

On the other hand, various services have been proposed to use the multimedia functions of the digital TV, but location-based interactive multimedia services combined with a mobile terminal and a mobile communication network, which are portable devices, have not yet been provided.

The present invention is to overcome the above-mentioned problems, a method, system, information providing server and mobile terminal for implementing a location information service that can check the location information of the mobile terminal in a digital television using a set-top box combined with a digital television To provide.

6 is a flowchart schematically illustrating a service registration procedure according to an embodiment of the present invention.

Referring to FIG. 6, first, the position information program of the digital television 110 (FIG. 1) is driven (S101). Thereafter, a password necessary for using the location information program later is set (S103). Thereafter, the identification number of the mobile terminal (200 in FIG. 1) to be used for location information search is input (S105). Then, the service registration request signal is transmitted to the information providing server (150 in FIG. 1) so that the information providing server 150 applies for service registration of the location information service (S107).

Subsequently, the mobile communication network (mobile communication service provider network 180 and mobile communication service provider server-LBSP 190) that has received the service registration application registers the service of the location information service (S109), and then services the service registration authentication number. Transmission to each identification number included in the registration request signal (S111). Then, the mobile terminal 200 corresponding to the identification number receives the authentication number (S113), and inputs the authentication number to the digital television 110 again (S115).

If so, the authentication number is again sent to the information providing server 150 (S117), the mobile communication network checks the authentication number sent to the information providing server 150 (S119), the authentication confirmation with the information providing server 150 It transmits (S121). Then, the information providing server 150 sends an authentication confirmation message to the digital television 110 (S123), and when the digital television 110 receives the authentication message, the registration procedure of the service is completed (S125).

7 is a flowchart for performing a location inquiry service according to an embodiment of the present invention.

Referring to FIG. 7, first, the digital television 110 (in FIG. 1) drives a location information program (S301). Thereafter, a password is input in order to use the location information program (S303), and a mobile terminal number of a target to know the location information is selected from previously stored phone number data (S305). Then, the location inquiry request signal of the selected mobile terminal is transmitted to the information providing server (150 of FIG. 1), and the information providing server 150 receives the location inquiry request (S307).

Thereafter, the information providing server 150 requests a location information service from the mobile communication network for each number of mobile terminals requesting location information (S309). In this case, the location inquiry request signal received from the digital television 110 may correspond to one mobile terminal, and may request the location inquiry of several mobile terminals at the same time. You can keep asking.

The mobile communication network checks the location information according to each mobile terminal that has received the location information (S311), and then sends a location information confirmation signal to the information providing server 150 (S313). The information providing server 150 receiving the location information confirmation signal transmits a signal in which the location information is modified in a form that can be confirmed by the digital television 110 (S315) to the digital television 110, and the digital television 110 is received. One location information is displayed on the screen (S317).

In this case, the display method may be generally displayed in text or graphics, and in particular, may be displayed so that the location information of the mobile terminal can be grasped at a glance using an avatar similar to the holder of the mobile terminal corresponding to the location information.

8 is a flowchart for performing a location inquiry service according to another embodiment of the present invention, and includes a location information service registration step and a location information service step.

First, the location information service registration step is the TMSP (160 of FIG. 1) of the information providing server (150 of FIG. 1) location information service request details from the digital television subscriber-where, the location information service request details, the family list of the service subscriber, Family MIN, including the relationship-is input (S501) to form a family list (S503). And mutual authentication is made between the mobile terminal (200 of FIG. 1) and the digital television (110 of FIG. 1) of the family included in the family list (S505).

When mutual authentication (S505) is completed, the mobile service provider server-LBSP (190 in FIG. 1) registers the mutual authentication list (S507). Then, initial user authentication is performed between the set-top box 120 of the service subscriber and the TMSP 160 of the information providing server 150 (S509).

On the other hand, after the location information service registration step procedure, the location information service step, the set-top box 120 of the service subscriber first requests the mutual authentication list inquiry to the TMSP 160 of the information providing server 150 (S511). Then, the TMSP 160 of the information providing server 150 confirms the service target (S513). In operation S515, the mobile communication service provider server-LBSP (190 of FIG. 1) is requested. Then, the mobile operator server-LBSP 190 returns the mutual authentication list result to the TMSP 160 of the information providing server 150 (S517).

The TMSP 160 of the information providing server 150 having received the mutual authentication list result extracts only the family of the service subscriber from the mutual authentication list (S519).
