As shown in FIG. 3, according to an embodiment of the present invention, the mobile communication terminal 10 receives an already reserved display schedule information for a display board device specifically designated among a plurality of display devices DU1 to DUn. Receives and can be inquired, transmits reservation information for displaying multimedia information of the specific contents intended by the subscriber of the terminal by designating time zones other than the already scheduled time zone, and transmits multimedia information to be displayed. do.

In this case, it is preferable to designate a display board device that is closest to the current position of the mobile communication terminal 10 by designating a specific display device by the mobile communication terminal 10, and to the plurality of display devices DU1 to DUn. It is also possible for the mobile communication terminal 10 to directly input and specify the identification number of a specific electronic display device in a state in which a unique identification number has already been assigned.

Accordingly, the session controller 20 registers reservation information for reservation of multimedia information display from the mobile communication terminal 10 in the reservation information management server 24, and the reservation information has already been designated and connected to the call board. The reservation is made by transmitting to the device DU1.

Next, the call session controller 20 transmits the multimedia information received from the mobile communication terminal 10 to the electronic display device DU1 in advance through the multimedia providing server 26.

Here, the session controller 20 selects the specific multimedia information stored in the multimedia information database 28 without transmitting the multimedia information owned by the mobile communication terminal 10 directly. It is also possible to receive the multimedia information selected by the corresponding mobile communication terminal 10 from the mobile communication terminal 10 and transmit the received multimedia information to the electronic display unit DU1.

Accordingly, the display panel device DU1 visually displays the multimedia information received in the time zone reserved by the mobile communication terminal 10 through the display display panel 42 installed indoors or outdoors.

Next, an embodiment of the present invention made as described above will be described in detail with reference to the flowcharts of FIGS. 4 and 5.

First, the mobile communication terminal 10 connects to the reservation information management server 24 through the session controller 20 in accordance with call connection processing from the wireless control station 12 and the packet wireless service processor 14 on the wireless communication network. Request information service on the display board (step S10), and the session controller 20 transmits the corresponding mobile communication terminal 10 according to the position detection process from the wireless control station 12 and the packet wireless service processor 14; ) Is detected and the electronic device of the position adjacent to the mobile communication terminal 10 is searched and detected by referring to the user information from the user information management server 22 (step S11).

When the display device adjacent to the current position of the mobile communication terminal 10 is detected, the call session controller 20 calls the display device to request a call connection (step S12), and the display device receives the call. The connection request is responded (step S13).

In this case, when the unique identification number is assigned to each of the plurality of billboards DU1 to DUn, the caller control unit 20 allows the mobile communication terminal 10 to designate an identification number of a specific billboard. In this case, it is possible to make a call connection by calling the display board device with the corresponding identification number.

Meanwhile, the call session controller 20 notifies the mobile communication terminal 10 that the call connection with the electronic display device is successful (step S14), and the mobile communication terminal 10 calls the electronic display device. In response to the notification of the connection success status, the electronic device requests a service reservation for displaying predetermined multimedia information (step S15).

Accordingly, the session controller 20 requests transmission of the reservation schedule information that is already scheduled for the billboard (step S16), and is stored in the memory module 36 in the control module 38 of the billboard. The reserved schedule information is transmitted to the session controller 20 (step S17).

Accordingly, the call session controller 20 transmits the reservation schedule information transmitted from the electronic display device to the mobile communication terminal 10 (step S18), and the mobile communication terminal 10 considers the received reservation schedule information. In step S19, the terminal subscriber searches for the reservation time.

In this state, the mobile communication terminal 10 reserves a specific service time (step S20), and the session controller 20 reserves the reservation on the reservation information management server 24 by the mobile communication terminal 10. One hour is registered (step S21).

The reservation information management server 24 notifies the occupancy state of the reservation time based on the time reserved by the mobile communication terminal 10, and the occupation of the reservation time is basically assigned at the time of one display reservation. It means the maximum information display time zone (step S22).

Next, the call session controller 20 requests the mobile communication terminal 10 to transmit the head media information (step S23), and the mobile communication terminal 10 stores the multimedia information stored therein. As it is transmitted, the multimedia information is stored in the multimedia information database 28 by the multimedia providing server 26 (step S24).

Accordingly, the reservation information management server 24 calculates the display occupancy time of the actual reservation service through the information display time of the multimedia information received from the mobile communication terminal 10 (step S25), and calculates as a result. The payment of the service use cost calculated according to the service occupancy time is requested (step S26).

On the other hand, the mobile communication terminal 10 is connected to the payment processing server 30 in accordance with the payment request from the reservation information management server 24 to perform the cost payment processing (step S27), the payment of the cost When the processing is completed, the call session controller 20 transmits the multimedia information transmitted by the mobile communication terminal 10 to the corresponding electronic display board through the multimedia providing server 26 (step S28).

In this state, the control module 38 of the electronic display device determines whether the time reserved by the mobile communication terminal 10 has elapsed by referring to the reservation schedule information (step S29).

As a result of the determination, when it is determined that the time reserved by the mobile communication terminal 10 has elapsed, the control module 38 of the electronic display device displays a reservation indication of multimedia information on the call session controller 20 of the mobile communication terminal. (10) is requested to be notified (step S30), and the session controller 20 calls the mobile communication terminal 10 to notify the display of the reserved multimedia information (step S31).

On the other hand, the control module 38 of the electronic display device reads out the multimedia information reserved from the memory module 36 and displays it on the display electronic display plate 42 according to the driving of the display driving module 40 (step S32).

Next, another embodiment of the present invention will be described in detail with reference to the accompanying drawings.
