When the download server 150 is connected to the content URL selected by the mobile terminal 100 through the IP network 130, the PDSN 120, and the base station 110, download reservation information of the corresponding content (for example, content URL information requested for reservation) is downloaded. , Reservation date, time, MIN, etc.) is stored in the reservation DB 170, the content URL information to the SMS server 180 and the Mobile Identification Number of the mobile terminal at the reservation date and time of the reservation DB (170) ) And request a download reservation to the mobile terminal 100. When the download server 150 requests content download from the mobile terminal 100 connected through the IP network 130, the download server 150 accesses the selected VOD content in the VOD content DB 160 and downloads the downloaded VOD content to the mobile terminal 100 ( Or streaming).

The VOD content DB 160 stores multimedia VOD contents (eg, a video image file, a music file, etc.) requested by the mobile terminal 100 in cooperation with the download server 150.

The SMS server 180 creates an SMS message having content URL information according to a request of the download server 150, and transmits the created SMS message to the IP network 130, PDSN 120, and when the download schedule date and time of the content is reached. The mobile station 100 transmits the MIN number through the base station 110. Although not shown in the figure, the SMS message configuration includes an OP (operation) code for controlling the mobile terminal, a link URL address which is a URL address of a WAP to which the mobile terminal is connected, a reservation value for displaying the linked URL, and the like. .

4 is a schematic diagram showing the internal configuration of a mobile terminal of the system to which the present invention is applied, wherein the mobile terminal 100 includes an antenna 101, an RF transmitter / receiver 102, and a digital analog convert (DAC) 103a. , ADC 103b, signal processor 104, CPU 105, memory 106, display 107a, key switch 107b, vocoder 108, speaker 109a, microphone 109b, etc. do.

Here, the RF transmitter / receiver 102 receives the high frequency signal transmitted from the base station through the antenna 101 and sends it to the ADC 103b, and transmits the digital signal of the DAC 103b to the base station through the antenna 101. Play a role.

The DAC 103a converts the digital signal transmitted from the signal processor 104 into an analog signal, and the ADC 103b converts the analog signal transmitted from the RF transmitter 102 into a digital signal. The signal processor 104 modulates a signal such as the vocoder 108 for the DAC 103a and demodulates the signal transmitted from the ADC 103b.

The CPU 105 controls the overall operation of the mobile terminal 100, and the memory 106 stores VOD contents and programs such as a WAP browser, a VOD play, and the like. The display 107a represents a display element such as an organic EL in the mobile terminal 100, and the key switch is a portion to which a key signal of the mobile terminal 100 is input.

The vocoder 108 outputs only the voice signal from the signal of the signal processor 104 to the speaker 109a or processes the voice signal input from the microphone 109b and transmits the voice signal to the signal processor 104.

Furthermore, the CPU 105 in the mobile terminal 100 of the present invention stores the content URL in the message in the memory 106 when the signal transmitted from the signal processing unit 104 is an SMS message. The CPU 105 transmits the stored URL address to the base station via the signal processing unit 104 or the RF transmitter 102 to control the wireless data network and the WAP server, and then executes a WML script having content information from the WAP server. The content capacity and the remaining capacity of the memory 106 are compared among the content information received in the WML strip. If the corresponding content capacity is smaller than the remaining memory capacity, the CPU 105 notifies the display 107a of insufficient memory capacity before proceeding with the content download service. Otherwise, the CPU 105 controls the content download service to continue.

5 is a flowchart illustrating a space reservation service method of VOD content of a wireless Internet according to the present invention. 3 to 5, the operation of the VOD content service system according to the present invention is as follows.

First, when the mobile terminal 100 executes the WAP browser and selects the WAP server connection from the VOD service menu of the WAP browser, the mobile terminal 100 is the base station 110 and the PDSN 120 and the IP network 130 which are wireless data networks. It is connected to the WAP server 140 through the (S100).

The WAP server 140 delivers a WAP page having a VOD content menu to the connected mobile terminal 100. The mobile terminal 100 receives the WAP page and stores it in the memory 106 to display the VOD content menu page on the WAP browser of the display 107a. The user selects any arbitrary VOD content after searching for content in the displayed content menu page (S102).

Accordingly, a signal for selecting an arbitrary VOD content is input from the key switch 107b, and when a reserved key signal is input thereafter, the CPU 105 of the mobile terminal 100 disconnects the session connection with the WAP server 140 and the base station ( 110), the PDSN 120 and the IP network 130 are controlled to access the download server 150 having the selected VOD content address. (S104 to S106)

If the mobile terminal 100 connected to the download server 150 sets a download reservation date, time, etc. of the reservation-selected VOD content, the download server 150 downloads the download reservation information from the base station 110 and the PDSN ( 120) and receives the reserved content URL information, the reservation date and time, and the MIN of the corresponding mobile terminal 100 through the IP network 130 and stores them in the reservation DB 170 (S108).

The download server 150 transmits the content URL information requested for reservation to the SMS server 180 and the MIN of the corresponding mobile terminal in cooperation with the reservation DB 170 and requests a download reservation to the mobile terminal 100. The SMS server 180 creates an SMS message having the content URL information according to the request of the download server 150, and when the download schedule date and time of the content is reached, the IP network 130, the PDSN 120, and the base station 110 Transmit to the mobile terminal 100 of the corresponding MIN number through (S110).

When the content URL of the SMS message received from the mobile terminal 100 is selected, a WAP browser is executed to the WAP server 140 of the corresponding content URL address through the base station 110, the PDSN 120, and the IP network 130. Connected. The WAP server 140 transmits detailed information (MO value, content URL, etc.) of the downloaded scheduled content to the mobile terminal 100 in the form of a WML script (S112).

Before the CPU 105 of the mobile terminal 100 temporarily stores the transmitted WML script in the memory 106 and downloads the content, the CPU 105 stores the content capacity in the content information in the corresponding WML script to reserve a memory capacity space. Compare with the remaining dose of 106. If the corresponding content capacity is larger than the remaining capacity of the memory 106, the CPU 105 notifies the display 107a that the memory capacity is insufficient and requests the user to secure the memory 106 capacity. If the content capacity is smaller than the remaining capacity of the memory 106, the content download service continues to proceed (S114).

When the memory space reservation of the mobile terminal 100 is completed, the mobile terminal 100 allocates a high speed channel from the PDSN 120 by changing a mux option according to the MO value received from the WAP server 140 through the WAP browser. The connection is terminated by stopping the WAP session with the WAP server 140 connected through the IP network 130. The mobile terminal 100 accesses the download server 150 through the base station 110, the PDSN 120, and the IP network 130 with the corresponding content URL in the detailed information in the WML script through the WAP browser. )

Then, the WAP browser of the mobile terminal 100 requests the download of the VOD contents reserved for download to the download server 150 connected through the IP network 130 using the DMIF protocol (S118). The display 107a of the display 100 displays the VOD content related information (content title, etc.) scheduled to be downloaded through the WML script received from the WAP server 140, and displays that the user is currently connected to the download server 150.

Then, when download / play is completed in VOD play of the mobile terminal 100, the mobile terminal 100 transmits a download / play command to the download server 150 using the DMIF protocol. The download server 150 sends a recognition command for the DMIF protocol to the mobile terminal 100, accesses the VOD contents reserved for download in conjunction with the VOD content DB 160, and accesses the mobile terminal 100 through the IP network 130. (S120) Then, the VOD player in the mobile terminal 100 receives the recognition command and receives the selected content as a download or streaming and stores it in the internal memory 106. Alternatively, they can be played simultaneously while being downloaded or streamed.

On the other hand, in step S104, if the mobile terminal 100 selects the real-time download without downloading the randomly selected VOD content, the system of the present invention proceeds with the download process as in the prior art.

That is, the mobile terminal 100 terminates the connection by stopping the WAP session with the WAP server 140 connected through the IP network 130, and uses the URL having the location and file name of the selected VOD content. Access to the download server 150 through the (S122).

The mobile terminal 100 requests the download server 150 to download the selected VOD content, and the download server 150 accesses the selected VOD content in association with the VOD content DB 160 to access the IP network 130 and the PDSN. The mobile terminal 100 transmits the selected VOD content by downloading or streaming to the mobile terminal 100 through the base station 110 and the base station 110 (S124 to S126). Play through the VOD player at the same time while receiving the.

As described above, when the VOD content download service is reserved, the present invention transmits an SMS message to the corresponding terminal at a reserved time to control access to the download server at the reserved time by the mobile terminal, but prior to downloading the content. Check the memory space in the download process only if the memory capacity is not enough.

Accordingly, the present invention can reduce the failure of content download due to insufficient memory capacity of the mobile terminal when the reservation service is downloaded to download VOD content at a desired time.

On the other hand, the present invention is not limited to the above-described embodiment, various modifications are possible by those skilled in the art within the spirit and scope of the present invention described in the claims to be described later.
