Description

Push Advertisement in Mobile Communication Network and Wireless Communication Terminal for the Same [Push Advertizement in Mobile Communications Network and Mobile Terminal Suitable for the Same}

The present invention relates to an advertisement method and an advertisement receiving apparatus through a network, and more particularly, to an advertisement method through a wireless communication network and a wireless communication terminal for implementing the same.

The supplier providing the product performs nonpersonal information providing activity, that is, advertisement, for promoting sales of the product or promoting the company. Traditionally, TVs, radios, newspapers, magazines, etc. have been widely used as advertising media. Recently, as the Internet develops, banner advertisements and interstitial advertisements on Internet contents are also widely used. In particular, SMS advertisements using a short message service (hereinafter, abbreviated as "SMS") provided by mobile phone providers as a medium are gradually increasing.

By the way, the simple SMS advertising currently implemented has some limitations in terms of advertising effectiveness. First, the short message delivered through SMS cannot be sufficiently delivered to the advertiser because the length of the short message is extremely short. More fundamentally, since mobile phones are primarily intended for interpersonal communication, most mobile phone subscribers are often uninterested in junk messages, such as advertising shorts. Throwing away is common. Given that most of the SMS advertising is Sales Promotion Advertising aimed at direct sales promotion, this phenomenon can cause significant concern for advertisers.

In order to enhance the effectiveness of SMS advertising, several ideas have been proposed. For example, Targeted Transmission described in Publication No. 2000-72755 (Invention: Method and System for Providing Advertisement in Network) published on December 5, 2000. According to this document, an advertiser or an advertising service provider selects an advertisement target that meets a predetermined condition, and transmits advertisement text only to the selected person. However, even with this targeted transmission, the phone user is basically not interested in the ad short message unless there is little incentive, and sending the ad without consent for receiving the SMS advertisement of the mobile subscriber is similar to spam mail. Can cause dissatisfaction.

Patent Publication No. 2000-30677 filed on June 5, 2000 (name of the invention: a target advertisement and active advertisement access method based on the Internet and a wireless mobile phone) and published on January 15, 2001 Publication No. 2001-0002782 (name of the invention: an advertisement system using a mobile communication device) describes a method and system in which an advertisement information provider provides advertisement information only to an applicant who has applied for receiving advertisement information data. According to these documents, the advertisement information provider rewards each advertisement information receiver with a certain reward upon receiving the advertisement information. However, in the case of SMS advertising, since the advertising price is not so high, it is difficult for the advertising information provider to provide a large amount of compensation for receiving the advertising to the advertising information receiver (ie, mobile phone subscriber). On the other hand, even in this case, since the recipient of the advertisement information can immediately delete the advertisement short message like the spam mail, it is difficult for the advertiser to expect a large advertisement effect.

On the other hand, because the advertisement message provided through SMS Push is short and simple text, it is difficult to sensibly appeal to the terminal user. Therefore, in order to enhance the advertising effect, it is desirable to provide an image advertisement in the form of a still image or a video, and if the terminal is not connected to the wireless Internet, it is practically difficult to provide such an image advertisement to the terminal. Advertisers and advertising agencies are looking for ways to increase the effectiveness of advertising more.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an advertisement method in a wireless communication network that can provide a large advertising effect to an advertiser and provide a substantial reward for receiving an advertisement to an advertisement information receiver. do.

On the other hand, the present invention is to provide a wireless communication terminal suitable for implementing a video advertisement in a wireless communication network that can provide a large advertising effect to the advertiser and can provide a substantial reward for receiving the advertisement to the advertising information receiver as another technical problem do.

However, in another embodiment, the advertisement video data may be received from the server by the swap push.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 schematically shows an example of a connection relationship between an advertisement providing system and a wireless communication terminal for implementing an advertisement method according to the present invention, and FIG. 2 schematically shows an implementation process of the advertisement method according to the present invention.

The advertisement providing system 10 of the present invention is provided to the wireless communication terminal 50 via a short message service server (SMSS) 32 and a short message service center (SMSC) 30 of a wireless telephone network. The short message may be transmitted, and the wireless communication terminal 50 may access the advertisement providing system 10 through, for example, the wireless Internet using a wireless application protocol (WAP).

As shown in FIG. 2, in executing an advertisement, the advertisement providing system 10 first transmits a short message to the terminal 50 via the SMSS 32 and the SMSC 30 (step 80). The short message includes a teleservice ID (TID) and a callback URL for accessing the advertisement providing system 10. In particular, in order to allow the terminal 50 to identify the short message sent by the advertisement providing system 50 from other short messages and automatically access the advertisement providing system 50 in response to the advertisement, as described below. The TID of the short message sent by the providing system 50 to implement the present invention preferably has a different value from the general TID. For example, when the TID used for general text message transmission is "65490", the TID of the short message of advertisements according to the present invention may be set to "65497". However, in another embodiment in which the present embodiment is modified, the short message of the present invention may be distinguished from the general short message by other parameters included in the short message instead of the TID.

Upon receiving the short message, the terminal 50 identifies whether the message is a general short message or an advertisement short message according to the present invention based on the TID. If it is determined that the received short message is an advertisement short message according to the present invention, the terminal 50 may provide an advertisement providing system by a callback URL through a wireless Internet based on a protocol (eg, WAP) supported by a wireless telephone network ( 10) (step 82). To this end, the terminal 50 is preferably loaded with a program module that attempts to automatically connect to the advertisement providing system 10 when a short message having a specific TID is received, which will be described in detail below.

When the terminal 50 accesses the advertisement providing system 10, the terminal user does not require consent or a specific action (for example, pressing a call button). In particular, when the wireless communication terminal generally receives a short message, the beep sounds, the LED blinks, and the backlight of the display is performed to notify the user of the message arrival, but the wireless communication according to the present invention When the terminal receives the short message, the terminal does not take this action and remains silent. Therefore, the user may not know whether the short message is received unless the call origination attempt is made. However, in the case of receiving a normal short message, the wireless communication terminal according to the present invention also of course to inform the user of the arrival of the message through the above operation.

On the other hand, for a call to access the advertisement providing system 10 in response to an advertisement short message, it is preferable that the wireless telephone operator does not charge by consultation with the advertisement providing system operator. In this case, the terminal 50 provides a special access number that is different from the conventional Network Access Identifier (NAI) for the connection to the advertisement providing system 10 so that the terminal 50 sets this number. It is necessary to connect to the advertisement providing system 10 by using.

When the terminal 50 accesses the advertisement providing system 10, the advertisement providing system 10 downloads one or more pieces of advertisement contents data to the terminal 50 (step 84). The advertisement content data is for displaying a still image or a video advertisement on the terminal display. For example, the advertisement content data has a format such as WBMP (Wireless Bitmap) or SIS (Simple Image Service, a trademark of Neo Mtel). After downloading the advertisement content data, the terminal 50 stores the advertisement content in the internal memory and ends the call processing (step 86). If a call is received or sent while the advertisement content is being downloaded, the download is interrupted, and then connection and download are performed again after a certain time.

In the state where the advertisement content data is stored in the memory, the terminal displays the advertisement image corresponding to the advertisement content data on the display whenever a specific event occurs (step 88). Examples of such an event in which the advertisement image is displayed include entering a standby state (flip or open a fault), attempting to access the wireless Internet, terminating the wireless internet, sending a short message, receiving a call, turning on / off the terminal, and the like. For example, an advertisement image is displayed on the display from the moment the terminal enters the standby state, which continues until the user presses the keypad for dialing or for other purposes. As another example, the advertisement image is displayed on the display from the moment when the user presses the wireless internet access button, for example, to connect to NATE (trademark of Escale Telecom Co., Ltd.), which is connected to the Nate server. Until or for a period of time.

When the advertisement content data is downloaded in step 84, control information regarding the advertisement display is provided together, so that this information can perform various controls in displaying the advertisement image. For example, when a user presses a specific key (for example, a "confirmation" key or a "call" key) of the terminal while the advertisement image is displayed, the user can be directly connected to the wireless Internet site associated with the advertisement to view details of the advertisement. . Meanwhile, the advertisement content data stored in the terminal may be large. In particular, such advertisement content data may be separately provided for each event. Furthermore, since a plurality of pieces of advertisement content data are stored for a specific event, a plurality of advertisement images mapped to the corresponding event may be rotated and displayed whenever an event occurs. Meanwhile, the advertisement content data is stored in the nonvolatile memory of the terminal 50, so that the stored state is maintained even when the power is turned off.

In one embodiment, such an advertisement method is performed only for the terminal of the user who made the advertisement reception request. In particular, such an application for receiving an advertisement may be made at the time of purchase of the terminal. In this case, the terminal is loaded with a program module necessary for receiving and displaying advertisement content data from the time of shipment. Various types of rewards can be provided, such as reduction or support, support for purchasing a terminal, and earning points. Of course, the application for receiving an advertisement or withdrawing the application may be made after the terminal is purchased. The method of applying for and withdrawing advertisements may be the same as for other value-added services implemented by a mobile phone provider. If the subscription request is withdrawn afterwards, the payment of the advertising reward system to the user is suspended. In the case of receiving a subscription afterwards, the counter-payment for the user may be a call charge support or point accumulation.

On the other hand, when a terminal user who is not loaded with a program for implementing the present invention applies for a reception request in this way, it is necessary to upgrade the terminal control program. On the other hand, it is necessary to deactivate the advertisement image display function of the terminal when the terminal user applies for cancellation of advertisement reception, and to reactivate the advertisement image display function of the terminal when the terminal user applies for advertisement reception again. The change of the advertisement display function activation / deactivation state in the terminal may be set using a short message, and the function activation / deactivation state is preferably stored in the nonvolatile memory of the terminal. A separate TID may be assigned to change an advertisement display function activation / deactivation state through a short message.

When a short message entity other than the advertisement providing system 10 according to the present invention registered in the SMSS 32 of the wireless telephone network transmits the short message using the same TID as the advertisement short message of the present invention. It will cause serious problems on the system. Therefore, when the SMSS 32 is requested to send a short message using the same TID as the short message of the present invention, the SMSS 32 checks the IP port of the requesting server and sends the short message only to the previously provided advertisement providing system 10. It may be necessary to allow the request.

3 illustrates an embodiment of the advertisement providing system of FIG. 1 and its network environment in detail. The advertisement providing system 10 according to the present embodiment is suitable for providing advertisement content data to a terminal based on WMLscript, and includes a main server 12, an advertisement phone server 14, and a download server 16. do.

In addition to the push advertisement according to the present invention, the advertisement providing system 10 operator executes various kinds of advertisements (for example, short message advertisement through short message service (SMS)). The main server 12 manages the plurality of advertisement businesses and manages the entire system 10. The advertisement phone server 14 performs the advertisement according to the present invention. That is, the advertisement phone server 14 manages user-specific data for implementing the present invention and selects an advertisement target, and transmits a short message to the user terminal 50 through the SMSS 32 and download server. (16) cause the user terminal 50 to download the advertisement content data. The download server 16 stores a plurality of advertisement content data, identifies each terminal based on the terminal number, and provides WAP contents in response to a request of the terminal. In particular, according to the present embodiment, the WAP content provided by the download server 16 includes a WML script for providing advertisement content data unique to each terminal to the corresponding terminal.

In the radiotelephone network 20, a radio base station 22 is connected to a plurality of base stations 24 for relaying call signals transmitted and received between the terminal 50 and the exchanger 22. The radiotelephone network 20 is connected to a single base station 24. A central gateway switch (CGS) and a plurality of wireless exchangers connected thereto may be included, but only one exchange is shown for simplicity. In addition, the WAP gateway 28 is connected to the wireless switch 22 through an interworking function 26. The IWF 26 is a gateway that allows a wireless communication network and a wired communication network to be connected. Since the device is well known to operators in the wireless communication field, detailed description thereof will be omitted. The WAP gateway 28 performs the function of converting the HTTP protocol stack into the WAP protocol stack and conversely converting the WAP protocol stack into the HTTP protocol stack.

On the other hand, the short-term service center (SMSC) 30 for providing a short message service is connected to the wireless switch 22, and at least one short-service server (SMSS) 32 is connected to the short service center 30 again. The short message service center 30 is connected to a switch of a wireless telephone network by a common line (SS No. 7) signaling method to store and transmit a short message transmitted and received by each terminal user, and the short service server 32 is connected to an external network. Perform the interlock function of.

The advertisement phone server 14 of the advertisement providing system 10 is connected to the short message service server 32 through a short gateway server 34. Therefore, the advertisement phone server 14 requests the short message service server 32 to transmit a short message to the terminal 50 via the SMS gateway 34. The download server 16 is connected to the WAP gateway 28 through a wireless interface gateway (WIG) 36, and downloads the advertisement data when the terminal 50 is connected. In another embodiment in which this embodiment is modified, the advertisement phone server 14 may also be connected to the SMSS 32 via the WIG 36.

In one embodiment of the present invention, the advertisement providing system 10 is operated by another operator other than the telephone operator operating the wireless telephone network 20. In this case, as described above, the download server 16 may be operated by the operator of the advertisement providing system 10, but may be operated by a telephone operator or a third party operator. Of course, the advertisement providing system 10 may be operated by the telephone operator. Meanwhile, although the main server 12, the advertisement phone server 14 and the download server 16 are shown separately in terms of functions in FIG. 3, some or all of these servers may be implemented in one physical server. It may be.

4 illustrates in detail the advertising method in the system and network environment shown in FIG.

First, the main server 10 shown in FIG. 3 registers the advertisement-related data about the advertiser and the advertisement content of the advertiser and the target group to which the corresponding advertisement is to be executed in the advertisement phone server 12 (step 100). The ad phone server 14 registers the advertisement content with the download server 16 (step 102). In step 104, the advertisement phone server 104 requests the SMS gateway 34 to send a short message to the terminal 50 belonging to the target group, and in response to the request, the SMS G / W 34 In step 106, the short message in which the TID is set as the advertisement TID is sent to the terminal 50 through the SMSS 32. The SMSS 32 preferably queries the base station information for determining the location of the terminal in advance, and distributes the short message at the minimum time of the IWF system in consideration of the load of each base station. On the other hand, upon receiving an acknowledgment (ACK) signal from the terminal 50, the SMSS 32 reports the sending result to the SMS gateway 34 (steps 108 and 110).

Subsequently, the terminal 50 receiving the short message is automatically connected to the download server 16 with reference to the callback URL (step 112). When the terminal 50 is connected, the download server 16 provides WAP content, and the WMLscript included in the WAP content downloads predetermined advertisement content data for the terminal 50 (step 116). ). When the download is completed, the download server 16 reports to the ad phone server 14 that the download is complete (step 118). Meanwhile, the short messages that fail to transmit properly in step 106 may attempt to resend one or more times.

When the advertisement content data is downloaded, the WMLscript executed on the terminal 50 stores the data in a memory, and displays the advertisement image on the display whenever a specific event occurs as mentioned above. (Step 120). Details of the advertisement exposure will be described later. On the other hand, the main server 12 may receive an advertisement result and analysis results by querying the advertisement result to the advertisement phone server 14 each time each advertisement is made or periodically (step 122).

On the other hand, in step 116, immediately before or immediately after the download, the existing advertisement analysis result data of the corresponding terminal is transmitted from the terminal to the advertisement phone server 14. The advertisement analysis result format may include a terminal number, an advertisement ID, exposure screen information, an advertisement cumulative impression number, an advertisement exposure start time, an advertisement exposure end time, and the like, which is transmitted to an advertisement server to display an advertisement response result. Used to clarify.

5 illustrates an example of the wireless communication terminal illustrated in FIGS. 1 and 3. In the illustrated terminal 50, the RF transceiver 202 receives a radio signal through the antenna 200, converts it into a baseband signal, and converts an analog / digital conversion and a digital / analog conversion unit (ADC / DAC). , 204, and converts the baseband signal output from the ADC / DAC 204 into a high frequency band and outputs the same through the antenna 200. The ADC / DAC 204 converts analog signals from the RF transceiver 202 into digital data and provides them to the digital processor 206. The ADC / DAC converts digital data from the digital processor 206 into analog signals. Provided at 204.

The digital processor 210 includes a modem 208, a voice codec 210, and a control program 212. Modem 208 accepts down-modulated data from ADC / DAC 204 and demodulates by spectral despreading, and modulates upstream data from voice codec 210 by spectral spreading. The voice codec 210 decodes the demodulated data and outputs the decoded data to the speaker 220 via the amplifier 218. The voice codec 210 receives and encodes a voice signal input from the microphone 222 through the amplifier 224 and encodes the encoded data. To the modem 208.

The control program 212 controls the operation of the entire internal circuit of the terminal, including the modem 208 and the voice codec 210. The control program 212 can access the RAM 214 and the flash memory 216. The RAM 214 temporarily stores data temporarily generated during the operation of the terminal. Flash memory 216 stores at least some of personal information such as address books and message archives and control program code. In particular, according to the present invention, the flash memory 216 stores the advertisement data downloaded from the advertisement providing system 10, so that the control program 212 displays the advertisement image corresponding to the advertisement data through the LCD 228 It allows you to.

Meanwhile, the LCD 228 is connected to the digital processor 206 through the LCD driver 226, the keypad 230 is connected through the keypad interface 232, and the LED 234 is directly or through a separate interface. Connected.

FIG. 6 schematically illustrates the structure of an embodiment of the terminal control program 212 shown in FIG. The control program 212 includes a user interface module 250, a call processing module 252 and a short message processing module 254. The user interface module 250 displays the current operating state of the terminal and other information on the LCD 228 and accepts user input information from the keypad 230. The call processing module 252 controls the operation of the modem 208 and the voice codec 210 to allow a call to be sent or received, and to facilitate communication while the call path is established. The short message processing module 254 sends the short message through the call processing module 252 according to the instruction of the user interface module 250 and processes the short message received through the call processing module 252.

In particular, in the present embodiment, the short message processing module 254 includes a display / storage routine for processing a normal short message and an automatic connection routine for processing an advertisement short message according to the present invention. If the short message received through the call processing module 252 is a normal message, the display / save routine causes the user interface module 250 to display the message content on the LCD 228 as well as the flash memory 216. Save to DB of). On the other hand, when the received message is an advertisement short message according to the present invention, the short message processing module 254 does not indicate the message arrival fact on the LCD 228 and does not store it in the DB and causes the call processing module 252 to cause the call short message. The callback URL is used to connect to the download server 16. This function is performed by an automatic connection routine.

In this embodiment, the terminal control program 212 shown in Figs. 5 and 6 is loaded into the flash memory 216, and is loaded into the digital processor 206 and executed when the terminal is turned on. 6 shows WML scripts ("SetADImage () function" and "UploadStatus () function") that are received and executed from the download server 16 of the advertisement providing system 10. As mentioned above, the SetADImage () function downloads the advertisement content data stored in the download server 16 and stores it in a designated location in the flash memory. UploadStatus () function uploads the advertisement analysis result data stored in the flash memory of the terminal to the download server 16.

The parameters of the SetADImage () function and its meaning or function are particularly important as follows.

parameter type function url String Absolute path of the ad image file title String Image file title to be saved in the terminal kindofimage essence Kindofimage = 0: Image to be displayed when the device is turned on kindofimage = 1: Image to be displayed when the device is turned off kindofimage = 2: Image to be displayed on the idle screen kindofimage = 3; Image to be displayed at kindofimage = 4: image to be displayed when accessing the wireless internet kindofimage = 5: image to be displayed when sending a short message kindofimage = 6: image to be displayed when the wireless internet connection is terminated) imagetype essence Refers to the data format of the image file (imagetype = 0: WBMPimagetype = 1: SISimagetype = -1: as an animation, one-time exposure for 5 seconds, then converted to the original state)

The SetADImage () function processes the advertisement image data and returns a return value to the download server 16. Accordingly, the download server 16 can check whether the data processing has been successfully completed in the terminal. As described below, a plurality of advertisement contents may be stored in the terminal, and several content files may be transmitted from the download server 16 to the terminal in one download session. In this case, N advertisements are transmitted by repeatedly using the SetADImage () function with different parameters or by defining similar functions as necessary. In addition, the WAP content provided to the terminal by the download server 16 automatically connected by the callback URL includes advertisement control information, which will be described later.

Meanwhile, when the short message processing module 254 transmits and receives a short message indicating a change of the advertisement display function activation / deactivation state in the terminal, the short message processing module 254 displays the advertisement display flag of the flash memory 216 in a display enable mode or a display disable mode. Set to either. When the advertisement display flag of the flash memory 216 is set to the display enable mode, the user interface module 250 should call the advertisement content data stored in the flash memory 216 whenever the above-described event occurs. An advertisement image is displayed on the LCD 228. Accordingly, the advertisement image stored in the terminal is displayed only when the user applies for advertisement display and the advertisement display flag is set to the display enable mode.

Hereinafter, the advertisement data download and advertisement exposure process in the wireless communication terminal 50 will be described in more detail with reference to FIGS. 7 to 10.

7 shows a process in the case where the wireless communication terminal 50 receives a short message. When the short message is received in step 300, the short message processing module 254 checks the TID, and determines whether the short message is the advertisement short message of the present invention (step 302). If it is determined in step 302 that the short message is not the advertisement short message, the short message processing module 254 processes the message according to a general short message processing routine (step 304). That is, the short message processing module 254 stores the received short message in the message inbox of the flash memory 216 and notifies the user interface module 250 of the arrival of the message. Accordingly, the user interface module 250 The envelope icon is displayed on the LCD 228 and a beep sounds through the speaker 220 while blinking the LED lamp 234 for a predetermined time.

On the other hand, if it is determined in step 302 that the short message is an advertisement short message, the short message processing module 254 does not store the corresponding message in the message inbox of the flash memory 216 and sends the message to the user interface module 250. It does not notify the arrival (step 306). Thus, despite receiving the short message, the arrival guidance through the envelope icon, the LED lamp 234 and the speaker 220 is blocked. In addition, the short message processing module 254 provides the callback URL to the call processing module 252, so that the call processing module 252 attempts to access the download server 16 through the WAP. When the terminal 50 is connected to the download server 16, the corresponding terminal number is provided to the download server 16 from the WIG 36. The download server 16 checks whether the corresponding terminal user is the person who applied to receive the advertisement according to the present invention based on the terminal number data and downloads the advertisement content data for the corresponding terminal (step 308).

The data that the download server 16 provides to the terminal through one or more consecutive sessions forms a series of data frames. An example of such a data frame structure is shown in FIG. 8. As shown, the data frame includes a frame header 350, control information 352, and a plurality of advertisement image data 354, 356, and 358. The frame header 350 includes information about the file size (total_file_size), the number of advertisements (total_AD_count), the control information size (control_info_size), the time span start point (start_time_span), and the time span period (time_span_term) of the entire frame. Here, the time span means a period in which the advertisement exposure counter is reset to restart the count, and the time span starting point means a time point at which the calculation of the first time span starts. On the other hand, the control information 354 represents a mapping rule for storing each advertisement image data in the flash memory 216.

Each advertisement video data includes information about the corresponding advertisement video (AD [n] _info, n-th advertisement information) and a video advertisement content file (AD [n] _data_compressed, n-th advertisement). Each piece of advertisement information (AD [n] _info) includes the size of the advertisement (AD_size), the advertisement ID (AD_ID), the exposure screen information (showing_position), the daily target count (daily_target_count), the expiration date (expiration_date), and the advertisement URL ( Information such as AD_URL). The advertisement URL AD_URL is a URL for directly accessing a wireless Internet site associated with the advertisement by pressing a specific key of the terminal when the advertisement is exposed.

Referring to FIG. 7 again, as mentioned above, the WML script stores the advertisement compression file in the mapped space in the flash memory (step 310).

9A illustrates an example of allocation of advertisement image data storage space in the flash memory 216 of the wireless communication terminal. As illustrated, the flash memory 216 has a user storage space 370 that allows a user to arbitrarily store a photo or other image, an advertisement dedicated space 372 for storing advertisement image data, and an application program stored therein. Storage space 374. In the advertisement-only space 372, it is preferable to prohibit the user from recording data. The application storage space 374 stores advertisement response result information, that is, statistics about exposure of the advertisement image to the user. Meanwhile, apart from the advertisement image data, a DB of the flash memory 216 is provided with an advertisement address information management table as shown in FIG. 9B. Assuming that the advertisement image data file is physically stored as shown in FIG. 9C in the advertisement-only space 372 shown in FIG. 9A, the address information management table stores the address where each advertisement image file is stored, thereby exposing the advertisement. The user interface module 250 makes it easy to call each advertisement video file.

Meanwhile, in the preferred embodiment, the advertisement exposure screen management table shown in FIG. 10 is additionally provided in the flash memory 216 of the wireless communication terminal. The management table stores advertisement image files to be displayed for each event and data on the exposure status of each image. In the example shown, the advertisement image is displayed when any one of the seven events occur, such as "waiting", "wireless internet access", "sms transmission", "phone reception", "wireless internet termination" , "Terminal on" and "terminal off".

Among these events, three advertisement image files (* -1, * -2, * -3) having different screen_IDs are mapped to the "waiting", "wireless internet access" and "sms transmission" events, respectively. Three advertisement images are rotated and displayed for the event type of. For example, if the ID of the previous "Standby" screen is "1-1" and the advertisement ID (AD_ID) is "AD_1" is exposed, then the ID of the screen is "1" when the next "Standby" event occurs. -2 "to display the advertisement image having the advertisement ID (AD_ID)" AD_2 ". To this end, the pointers p1-p7 provided for each event type indicate a screen ID displayed immediately before or a screen ID displayed next. On the other hand, in the case of "telephone reception", "wireless internet termination", "terminal on", and "terminal off" events, only one advertisement video file is mapped for each event type so that the valid period of the file is not expired. Advertising images are fixedly displayed.

As described above, in the present embodiment, three screen_IDs are assigned to three types of events among seven types of events, and there are a total of 13 screen IDs. The advertisement image file mapped to each of the 13 screen IDs may be partially or entirely overlapped. In other words, some advertisement video files may be displayed for two or more events. For example, an advertisement image having an advertisement ID of "AD_1" may be displayed not only in a "waiting" event but also in a "wireless internet access" or "telephone reception" event. In the example of FIG. 10, it can be seen that six advertisement images are partially overlapped and mapped to 13 screen IDs.

The validity period of the advertisement image file is set for each screen ID, and is displayed on the terminal only until the validity period. If no new advertisement image file data is provided from the advertisement providing system 10 by the validity period, an advertisement image set as a default image is displayed. On the other hand, an advertisement exposure target value, that is, a target count, to be exposed for one day for each screen ID or event is set, and a daily exposure count indicating the number of times the terminal has been exposed to the actual advertisement is stored in the table. The daily impression count indicates the number of times the exposure was made on a daily basis. If the daily impression count reaches the target count, the advertisement is no longer displayed.

However, to prevent abuse, it is not recognized as an advertisement exposure when the terminal folder is repeatedly opened and closed (for example, repeated within 2 seconds), and as described above, the time span and time span periods are Will be utilized. That is, it is desirable to allow the user to watch the advertisement video at least a certain number of times when the event occurs by restarting the daily exposure count at a constant time span period. For example, the number of advertisement exposures may not be separately counted in the case of a "telephone reception", "wireless internet termination", "terminal on", and "terminal off" events. In addition, the advertisement image may be displayed when an event occurs for a predetermined time every day regardless of the daily exposure count.

11 illustrates a process of determining and displaying an exposure advertisement image in a wireless communication terminal. The event processing function Event_Handler () in the user interface module 250 of the terminal control program continuously checks the state change of the terminal (eg, key input, folder / flip opening, power exhaustion, etc.). This state change is referred to herein as an interrupt event, and whenever such an interrupt event occurs, the Event_Handler () function performs the process of FIG.

First, the function determines whether the generated event is an event to which advertisement display is to be performed (operation 400). If the generated event is not an event for which advertisement display is to be performed, the process returns to the waiting state for waiting for the interrupt event again. However, when it is determined that the event generated in operation 400 is an event to be displayed, the event in which the plurality of advertisement images are rotated and displayed (that is, "wait", "wireless Internet access" in the example of FIG. 10). Or "SMS transmission" event (step 402). When it is determined that the generated event is not an event in which a plurality of advertisement images are rotated and displayed, and only one advertisement image is mapped, the process proceeds to step 416 and the advertisement image mapped to the corresponding event is displayed on the LCD 228. Will be displayed on.

If it is determined in step 402 that the generated event is the event in which the plurality of advertisement images are rotated and displayed, the advertisement ID AD_ID to be displayed is determined using a pointer to the corresponding event (step 404). Next, it is determined whether the validity period of the advertisement ID determined in step 404 has passed (step 406). If the validity period of the advertisement ID has elapsed, the default image (for example, a default image loaded at the time of shipment of the terminal or arbitrarily set by the user) is displayed, and then the display returns to the standby state waiting for an interrupt event. On the other hand, if the validity period of the advertisement ID has not elapsed, it is determined whether the daily impression count value is smaller than the target count (step 410). If the corresponding advertisement image is already exposed on the same day and the daily exposure count value is the same as the target count, in step 412, the daily exposure count and the pointer are increased, and then steps 404 to 410 are repeated. If the daily exposure count value is the same as the target count for all the advertisement images, the process returns to the waiting state for the interrupt event. If the daily exposure count value is smaller than the target count in operation 410, the advertisement image is displayed after increasing the daily exposure count and the pointer (operation 414 and operation 416).

The advertisement providing system 10 holds advertisement data information currently stored in the terminal for all the terminals of the user who applied for service use. 12A illustrates an example of a terminal-specific final advertisement information table maintained by the advertisement providing system 10. The final advertisement information table stores the demographic information of the user and the advertisement exposure data for all terminals, and records the type of advertisement image data. In FIG. 12A, in order to improve understanding, the advertisement ID is briefly displayed as one letter A to F unlike in FIG. 10. In addition, the question mark (?) Indicates a default image unique to the terminal.

The advertisement providing system 10 performs targeting transmission in consideration of demographic data for each user and a response result for the advertisement, based on the advertisement information management table as shown in FIG. 12B. An example of an advertisement sending scenario until the final advertisement information table as shown in FIG. 12A is generated is as follows. Suppose that the data is sent three times, but the first time, before January 31, 2002, to send men and women in their thirties before the advertisement video data as shown in Table 2, such data is the terminal (MIN1, MIN2, MIN4, MIN8) , MIN11) is sent and stored.

Ad exposure screen 1-1 1-2 1-3 2-1 2-2 2-3 … 7 AD_ID A B C A B C … D

In the second, suppose that advertising video data such as Table 3 is sent to men and women in their 20s before January 31, 2002, and the data is sent to and stored in the terminals MIN3, MIN5, MIN7, MIN10, and MIN12. do.

Ad exposure screen 1-1 1-2 1-3 2-1 2-2 2-3 … 7 AD_ID A D E A D E … D

The third time, on the 2nd day of February 2002, assuming that women in their 20s and 30s are sent only to those whose B files have expired on the screens (2-1) and (2-2), Is sent to and stored in the terminals MIN2, MIN5, MIN8, and MIN12. In this case, the data need not be sent to other advertisement exposure screens that have not yet expired, and only data about the screens having expired expiration dates need to be sent. Therefore, in this case, only the advertisement image data shown in Table 4 below is included in the advertisement compressed file and sent.

Ad exposure screen 1-2 2-2 7 AD_ID F F F

In the terminal receiving the advertisement compressed file, the image data of the advertisement exposure screen is changed from the existing "B" to the "F" when the expiration date has expired. On the other hand, in the terminals MIN1, MIN4, and MIN11 that such files have not been downloaded yet, the basic images described above are displayed on the screens 1-2, 2-2, and F, in which the image “B” is previously displayed.

3 to 9, the WML script provided by the download server 16 of the advertisement providing system 10 stores the advertisement content data in the terminal. However, in another embodiment in which this embodiment is modified, a virtual machine (V / M) loaded on the terminal may perform this function instead of the WML script. Figure 13 shows an advertisement providing system and its network environment according to such an embodiment.

In the embodiment shown in FIG. 13, the advertisement providing system 450 includes a main server 452 and an advertisement phone server 454. The functions of the main server 452 and the ad phone server 454 are similar to those shown in FIG. However, in FIG. 13, the content download server 460 for providing the advertisement video content is illustrated as being disposed outside the advertisement providing system 450. In this case, the download server 460 may be operated by a wireless telephone provider or a separate virtual machine solution provider. However, it is a matter of course that the download server 460 may be directly operated by the advertisement providing system 450.

When the terminal 50 receiving the short message of advertisement is automatically connected to the advertisement providing system 450, the advertisement providing system 450 redirects the connection to the download server 460 so that the download server 460 receives the connection. To provide advertising content to the terminal. In the present embodiment, it is preferable that the advertisement content to be provided to the terminal 50 is in a form in which one or more advertisement image files are compressed and formatted into a predetermined frame. The frame of the advertisement compression file includes control information on advertisement exposure, and the advertisement storage V / M of the terminal functioning as an advertisement dispatcher can use the information to perform various controls. After downloading the advertisement compression file, the terminal 50 releases the frame and decompresses the advertisement image data file to restore individual advertisement image data. Then, the terminal 50 ends the call processing after storing the advertisement data in the internal memory. If a call is received or sent during the download of a compressed advertisement file, the download is stopped, and connection and download are performed again after a certain time. As in the previous embodiment, in the state where the advertisement data is stored in the memory, the terminal displays the advertisement image corresponding to the advertisement data on the display whenever a specific event occurs. When the user presses a specific key of the terminal while the advertisement image is displayed, the user can directly access the wireless Internet site associated with the advertisement to view detailed information about the advertisement.

14 illustrates in detail the advertisement method in the system and network environment shown in FIG.

First, the main server 452 registers the advertisement-related data about the advertiser and the advertisement content of the advertiser and the target group to which the advertisement is to be executed in the advertisement phone server 454 (step 470). The advertisement phone server 454 registers the advertisement content with the download server 460 and receives a service ID (SID) for the content (step 472). In step 474, the advertisement phone server 454 requests the SMS gateway 34 to send a short message to the terminal 50 belonging to the target group, and in response to the request, the SMS gateway 34 transmits a short message to the terminal. In step 476, a short message is sent. Upon receipt of the acknowledgment (ACK) signal from the terminal 50, the SMSS 32 reports the sending result to the SMS gateway 34 (steps 478 and 480).

Subsequently, the automatic connection virtual machine (V / M) of the terminal 50 receiving the short message is automatically connected to the download server 460 via the WAP gateway 28. That is, when the automatic connection V / M of the terminal 50 automatically accesses the advertisement phone server 454 with reference to the callback URL, the advertisement phone server 454 transmits the connection to the download server 460 (Redirect). (Step 482, step 484). In this case, the advertisement phone server 454 generates and provides a VMscript that specifies that the terminal can download VM advertisement content from the download server 460. On the other hand, in FIG. 14, it is assumed that the callback URL is set to the URL of the advertisement phone server 454. However, in the modified embodiment, the callback URL may be set to the WAP gateway 28. Even in this case, the WAP gateway 28 transmits a connection to the download server 460. When the terminal 50 is connected, the V / M content download server 460 downloads the advertisement compressed file including the predetermined content for the terminal 50 (step 486). When the download is completed, the download server 460 reports to the ad phone server 454 that the download is complete (step 488).

When the advertisement compression file is downloaded, the advertisement storage V / M of the terminal 50 decompresses the file and stores each advertisement video content file and control information in memory, and as described above, whenever a specific event occurs. Display advertising video on the display. Accordingly, the advertisement may be exposed to the terminal user (operation 490). Details of the advertisement exposure will be described later. On the other hand, the main server 452 may receive an advertisement result and analysis results by querying the advertisement result to the advertisement phone server 454 whenever each advertisement is made or periodically (step 492).

FIG. 15 schematically illustrates an example of a program loaded on a terminal suitable for the advertisement method of FIG. 14. The control program 212a includes a user interface module 250a, a call processing module 252a, a short message processing module 254a, an automatic connection V / M 256, and an advertisement storage V / M 258. The user interface module 250 displays the current operating state of the terminal and other information on the LCD 228 and accepts user input information from the keypad 230. The call processing module 252a controls the operation of the modem 208 and the voice codec 210 to allow the call to be sent or received, and to facilitate communication while the call path is established. The short message processing module 254a sends the short message through the call processing module 252 according to the instruction of the user interface module 250a, and processes the short message received through the call processing module 252.

In particular, in the present embodiment, the short message processing module 254a causes the user interface module 250a to display the message content on the LCD 228 when the short message received through the call processing module 252 is a normal message. In addition, the data is stored in the DB of the flash memory 216. On the other hand, when the received message is an advertisement short message according to the present invention, the short message processing module 254 does not indicate the message arrival fact on the LCD 228 and does not store it in the DB and does not automatically connect the V / M (256). ) To connect to the ad phone server 454 using the callback URL. On the other hand, when the short message processing module 254 transmits and receives a short message indicating a change of the advertisement display function activation / deactivation state in the terminal, the short message processing module 254 displays the advertisement display flag of the flash memory 216 in the display enable mode or display display. Set to any of the enable modes.

The automatic connection V / M 256 automatically connects to the V / M content download server 460 through the advertisement phone server 454 according to the instruction of the short message processing module 254. While connected to the download server 460, the advertisement storage V / M 258 downloads the advertisement compression file personalized and configured in the corresponding terminal, decompresses it, and stores it in the flash memory 216. In this embodiment, the auto-connect V / M 256 and the advertisement store V / M 258 are stored in the application program space 374 of FIG. 9A and are loaded into the RAM and executed at the same time as or after the terminal is turned on. . These V / Ms may be loaded in the terminal from the time of shipment of the terminal into the memory, or may be loaded by a program upgrade operation of the user after shipment. Also, these two V / Ms can be separate scripts or merged into one.

When the advertisement display flag of the flash memory 216 is set to the display enable mode, the user interface module 250 should call the advertisement content data stored in the flash memory 216 whenever the above-described event occurs. An advertisement image is displayed on the LCD 228.

Other features of the systems and methods shown in FIGS. 13 and 14, respectively, are similar to those in FIGS. 3-4, and thus detailed descriptions thereof will be omitted.

In the above-described embodiments, although the advertisement providing system provides the URL to the terminal by SMS push so that the terminal accesses the system, the advertisement image data is provided, but in another embodiment of the present invention, the WAP push The advertisement image data may be provided to the terminal. Fig. 16 shows a connection relationship between the advertisement providing system and the wireless communication terminal in this embodiment. FIG. 16 is similar to FIG. 3 and FIG. 13 except that a Push Proxy Gateway (PPG) is added and the configuration of the advertisement providing system is more simply shown.

In the advertisement providing system 510, the main server 512 manages the entire system 510 and manages a plurality of advertisement projects executed by the advertisement providing system operator. Ad phone server 514 performs the advertisement according to the present invention. That is, the advertisement phone server 514 manages user-specific data for implementing the present invention and performs a process of selecting an advertisement target. In addition, the advertisement phone server 514 may provide information and advertisements about the target terminal selected to the push proxy gateway 520 to request that the advertisement be pushed to the target terminal.

The push proxy gateway (PPG) 520 receives push content from the advertisement phone server 514 by a push access protocol (PAP), converts it into a form suitable for a wireless network, and transmits it to the terminal using a push over the air (OTA) protocol. do. For this purpose, the PPG 520 is connected to the advertising phone server 514 and to the IWF 26 via the WAP gateway 28. Meanwhile, the WAP gateway 28 provides the PPG 520 with information about a terminal in which the WG session is currently formed in the PPG 520, so that the PPG 520 can refer to pushing contents to the terminal. Do it. For more information about WAP Push and PPG 520, see "WAP Push Architectural Overview (WAP-250-PushArchOveriew- 20010703-a)" , "Push " in the WAP Forum (trademark of Wireless Application Protocol Forum Ltd.). Message (WAP-251-PushMessage-20010322-a) " , " Push Proxy Gateway Service (WAP-249-PPGService-20010713-a) ", and the like.

FIG. 17 schematically illustrates the structure of a program loaded and executed in the terminal of FIG. The call processing module 560 controls the operation of the modem and the voice codec so that the call can be sent or received, and communication can be performed smoothly while the call path is established. The user interface module 562 displays the current operating state of the terminal and other information on the LCD and accepts user input information from the keypad. The short message processing module 564 sends the short message through the call processing module 560 according to the instruction of the user interface module 562 and processes the short message received through the call processing module 560.

In particular, in this embodiment, the short message processing module 564 causes the user interface module 562 to display the message contents on the LCD when the short message received through the call processing module 560 is a normal message. In addition, it is stored in the DB of the flash memory, but if the message is a Session Initiation Request (SIR) of the present invention sent by the PPG 520, it will be stored in the DB without indicating the message arrival fact on the LCD Rather, the WAP access management module 516 connects to the wireless Internet and establishes a push session with the PPG 520.

The application dispatcher 568 looks at the header of the push message when the content is pushed from the PPG 520, determines an application to use the content, and provides the application to the application. In particular, in accordance with the present invention, the application dispatcher 568 provides the advertisement storage virtual machine (V / M) 570 when the advertisement compression file is pushed from the PPG 520. In this case, the advertisement storage V / M 570 performs a function similar to the WAD script SetADImage () function described above. The advertisement storage V / M 570 receives the advertisement compressed file from the application dispatcher 568 and decompresses the advertisement. Store images in memory. The stored image data is called and displayed by the user interface module 562 whenever a specific event occurs.

FIG. 18 shows an advertisement method implemented in the network of FIG.

First, the advertisement phone server 514 transmits a push request message including the target terminal number and the advertisement compressed file to the PPG 520 (operation 580). Upon receiving the push request message, the PPG 520 checks whether a valid WAP session is established for the terminal 550 (step 582). As described above, the PPG 520 may receive information about a terminal on which a current WAP session is formed from the WAP gateway 28 periodically or in real time, and determine whether to establish a WAP session for each terminal. However, in an embodiment in which this embodiment is modified, whenever the PPG 520 is needed, the WAP gateway 28 may query whether the WAP session is established for a specific terminal.

If it is determined in step 584 that there is a valid WAP session for the terminal, the flow proceeds directly to step 592. On the other hand, when it is determined in step 584 that no valid WAP session exists for the terminal 550, the push session setting process of steps 586 to 590 is performed.

First, in step 586, the PPG 520 transmits a Session Initiation Request (SIR) to the terminal 550 through a short message. In order for the terminal 550 to identify and respond to the SIR short message sent by the PPG 520 from other short messages, the TID of the SIR short message sent by the PPG 520 is different from the general TID. It is preferable to have. For example, when the TID used for general text message transmission is "65490", the TID of the SIR short message may be set to "65495". However, in another embodiment in which the present embodiment is modified, the short message of the present invention may be distinguished from the general short message by other parameters included in the short message instead of the TID.

If it is determined that the received short message is the SIR short message, the short message processing module 564 of the terminal 550 activates the WAP connection management module 566 (step 588). As a Session Initiation Application (SIA) that performs a push session establishment with the PPG, a push session between the PPG 520 and the terminal 550 is established through the execution of the WAP connection management module 566 (step 590).

If it is determined in step 584 that there is a valid WAP session for the terminal or a push session is established in step 590, in step 592, the PPG 520 transmits the advertisement compressed file to the terminal through the push session. Each time the content is pushed, the application dispatcher 568 of the terminal looks at the header of the push message to determine the application to use the content and provides it to the application. In particular, the application dispatcher 568 provides the advertisement image storage V / M 570 when the content pushed from the PPG 520 is an advertisement compressed file according to the present invention. The advertisement image storage V / M 570 receives the advertisement compression file and decompresses the advertisement image to store the advertisement images in the memory (step 594). When the reception of the advertisement compressed file is completed, the push session between the terminal 550 and the PPG 520 is released, and the call channel is also terminated. The stored image data is called and displayed by the user interface module 562 whenever a specific event occurs.

Meanwhile, the WAP push service defined so far by the WAP Forum is based on WML (Wireless Markup Language), MMF (Mobile Multimedia File Format), CO (Cache Operation), Service Indication (SI), and SL (Service). Loading). In the case of the Wireless Markup Language (WML), Mobile Multimedia File Format (MMF), and Cache Operation (CO) services, the content may be provided to the terminal by one-time push, but the service indication (SI) and service loading (SL) services In this case, only the URL of the CP is pushed and the terminal is used to access the CP. In implementing the advertisement content push according to the present invention, any of these services may be used. However, when pushing through an MMF service or a CO service, when it is determined in step 584 that the session exists, that is, when the terminal is connected to the wireless Internet, the PPG 520 ends the push operation and then You can try again. In the case of the CO service, it is suitable for updating the validity period of the data file already stored in the terminal. On the other hand, in the case of pushing the advertisement content using the service indication (SI) and service loading (SL) services, the application dispatcher 568 or the WAP access management module 566 automatically advertises without seeking the consent of the terminal user. It is desirable to connect to the providing system 510.

Those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. For example, as described above, when the advertisement video content is provided to the terminal based on the SMS push, the terminal preferably performs tasks such as automatic access to the server, content reception, storage, and reporting. While some examples have been described for implementing these tasks, the use of embedded programs, V / Ms, and script programs such as WMLscript can be combined in various ways. In addition, although there may be a separate program module or function for each of the above tasks, some of them may be integrated and vice versa.

On the other hand, while some embodiments described above have been described in that the content provided from the server to the terminal is compressed and transmitted, the specific compression scheme, whether to compress the whole frame or part, and part of the compression In the case of the compression portion and the like can be modified in various ways.

Although the callback URL is also sent in the short message transmission, instead of providing the callback URL, the default URL can be stored in the terminal and accessed using this URL.

Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

As described above, according to the present invention, the advertiser can provide a personalized advertisement based on the target, that is, the attributes of each mobile terminal owner. In addition, when considering that the mobile terminal has a characteristic of being carried for 24 hours, the advertiser may maximize the advertisement effect by the constant repeated exposure of the advertisement. Increased advertising effectiveness allows system operators to charge more advertising charges from advertisers and give substantial incentives to service users.

On the other hand, the service user feels little inconvenience because the advertisement data is downloaded only while the terminal is not used for voice communication or data communication.
