* Description of the symbols for the main parts of the drawings *

The advertisement system for a mobile communication terminal according to the present invention uses an image communication terminal called IMT-2000 to achieve the above object, which is capable of wirelessly transmitting a large amount of data such as a video and satellite. This is because it is possible to simultaneously transmit images through a video communication system both domestically and overseas, since the common frequency is selected through.

Therefore, in the advertising method through a video communication system capable of image processing, the step of pre-producing the image according to the offer and request of the advertiser; Processing the advertisement into an image; It consists of a step of transmitting and displaying the advertising data through the data transmission channel to the formed call.

In the above description, after the advertising fee is set according to the transmission time, date, zone, and duration of the advertisement, the carrier charges the determined advertising fee from the advertiser, and a part of the predetermined cost for transmitting the advertising image is displayed. It is possible to grant the benefit of the rate reduction to the user of the communication terminal.

Hereinafter, exemplary embodiments of an advertisement system for a mobile communication terminal will be described in detail with reference to the accompanying drawings.

(Example)

1 is a view illustrating an operation configuration of a call channel of an advertisement system for a mobile communication terminal according to the present invention.

The propagation delay time from the base station to the mobile station is possible by the mobile station pilot search window size.

In the case of the opposite mobile station to the base station, since there is no need to search for signals from neighboring base stations as in the forward direction, in principle, the reverse call channel search window size can compensate for the time delay caused by the reverse multiple reflections.

Therefore, the reverse call channel search window size should be specified by the size of forward SRCH_ WIN _A.

The reverse link is noncoherent (no pilot channel), so the quality is rather poor compared to the forward, as well as the maximum receive gain, which reduces the mobile station's transmit power, resulting in longer mobile battery life.

Therefore, in general, the reverse link receiver is configured with more fingers than the forward direction, and is configured to have a reception antenna diversity function.

In the case of such a reverse link, when the transmission of the same signal is repeated at an arbitrary position using a repeater, a new examination of the window size is necessary.

As shown in FIG. 1, the strength of a received signal directly received from a mobile station traveling toward the repeater to the base station is gradually weakened, and the signal strength received from the mobile station through the repeater is gradually increased.

In order to smoothly search and demodulate two received signals having different paths in the base station, the reverse call channel window size should be set to accommodate the time delay difference between the two signals.

Otherwise, reverse call truncation may occur with only a direct signal to the base station that is weakened without recognizing the signal coming from the increasingly received repeater.

Since the time delay factor is the same in the forward link, the signal received from the mobile station through the repeater is defined as a reflected wave, and the signal received directly from the base station to the mobile station is defined as a direct wave, and after analyzing the maximum time delay difference between the two signals, SRCH_WIN_A You must set a value.

As such an additional time delay factor, a repeater H / W time delay, a time delay of a transmission medium, and a time delay element of a converter for converting an RF signal into a signal of a transmission medium should be considered.

In addition, the optical repeater has the largest time delay factor among several types of repeaters, so direct analysis is required.

As shown in FIG. 2, the repeater H / W delay is mostly generated by the SAW filter used in the repeater RF circuit, and a time delay of 5 to 12 * sec for each of the transmission and reception paths is generated according to the characteristics of the SAW filter.

In particular, if the repeater gain is increased (low input, high output), the spurious signal of the transmit output becomes difficult to satisfy the radio law, and thus the sharper SAW filter is used. In this case, only one SAW filter delays the time by about 10p sec. This will occur. Conversely, for low gains (high inputs, low outputs), a less sharp SAW filter is sufficient, resulting in a time delay of 5a sec.

Therefore, when setting the repeater specification, this time delay factor should be determined considering the correlation with the reverse call channel window size.

In addition, in the case of an optical repeater, it is a time delay of a light path.

Light paths are characterized by an average sec / km slightly later than air propagation.

In the case of an optical repeater, a significant time delay of about 5 * sec occurs in an optical converter that converts an RF signal into an optical signal.

This factor of time delay should be thoroughly examined not only in the reverse call channel reception window size but also in the access channel time delay dimension described above, so as not to cause a problem in setting up a call in a repeater of a base station having a large cell radius.

According to such a delay time, the advertisement video can be sent through the video communication terminal.

In other words, the transmission of the video advertisement is delayed by about 2 to 3 seconds at the time when the user uses the video communication (transmission, reception, communication connection, TV viewing, image information use, etc.). It will be possible.

3, in the operation flow diagram of the advertisement system of the present invention, assuming that an advertisement image is transmitted through a channel, the user selecting advertisement through an additional service; Displaying the negotiated advertisement data through the screen of the video communication terminal when the send button is pressed to make a call; Making a call; In the case of receiving a call from the outside, when the reception button is pressed for reception, the advertisement data is displayed through the screen of the video communication terminal.

In addition, referring to FIG. 4, when the banner advertisement of the advertisement system of the present invention is selected, when an item for selecting the banner advertisement is designated through the video communication terminal, a series of advertisement groups are displayed on the screen. When a particular advertisement is selected, it has a flow of receiving the selected advertisement.

As described above, the advertisement system for the video communication terminal of the present invention can maximize the advertising effect, induce interest due to the advertisement, and can casually activate the use of the video communication terminal. Although the present invention has been described based on a limited embodiment as being a useful invention that can be used, the present invention is not limited to the above-described embodiment, and the present invention can display an advertisement image composed of a video or a text on a video communication terminal. Various changes and modifications may be made by those skilled in the art to which the present invention pertains without departing from the gist of the present invention, which naturally belongs to the scope of the present invention.
