Description

SERVICE METHOD FOR TRANSMITTING ORIGINATING MESSAGE OF MOBILE TERMINAL WITHOUT PAY OR AT A DISCOUNT

Technical Field

The present invention relates to a communication system, and more particularly to a service method for transmitting an originating message of a mobile terminal without pay or at a discount.

Background Art

In general, mobile phone users transmit text, voice, images, etc., at corresponding costs using their own mobile phones . With the development of communication media such as mobile communication systems, text, voice and image services through communication networks are increasing and it is considered that a multimedia service integrating more of these services will be activated in the future. Therefore, the mobile phone users will pay a significant cost for general use of the multimedia service. On the other hand, keeping pace with such a development of the communication media, manufacturers, distributors, service providers, etc. transmit advertisements such as sales promotions or safety to their clients or many and unspecified persons in various ways including texts, voices and images through the communication media. Particularly, recent mobile phone advertisements are one-sidedly transmitted without prior consent of the mobile phone user. Therefore, many mobile phone users suffer from advertisement pollution due to an indiscriminate receipt of the mobile phone advertisements although there may be advertisements beneficial to the user among the mobile phone advertisements. If an advertiser provides the mobile phone users with a benefit, such as no charge or a discount, for message transmission of the mobile users to the other persons, and, as a repayment for this benefit, the mobile phone users must receive an advertisement from the advertiser in their mobile phones, it is advantageous to both the mobile phone users and the advertiser.

Best Mode for Carrying Out the Invention

Now, preferred embodiments of the present invention will be described in detail with reference to the annexed drawings. In the drawings, the same or similar elements are denoted by the same reference numerals even though they are depicted in different drawings. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Fig. 1 is a diagram schematically illustrating a service for transmitting an originating message of a mobile terminal to a destination terminal without pay or at a discount in accordance with an embodiment of the present invention.

Referring to Fig. 1, in the embodiment of the present invention, when a user of a calling party mobile terminal 2 transmits an originating message such as text, a voice or an image, along with a message free or discount transmission request code, to a called party terminal 6 via a public land mobile network (PLMN) 10 (shown in Fig. 2) (hereinafter, abbreviated as "mobile network") , a mobile switching center (MSC) 14 (shown in Fig. 2) of the public land mobile network- transmits the originating message from the calling party mobile terminal 2 to request a message transmission service for free or discount to a transfer server 4. The transfer server 4 transmits the received originating message from the mobile terminal 2 to the called party terminal 6 without pay or at a discount while transmitting a repayment advertisement message for the originating message transmission for free or discount of the mobile terminal, to an advertisement receipt terminal (e.g., the calling party mobile terminal 2). Fig. 2 is a block diagram of a service system for transmitting an originating message of a mobile terminal to a destination terminal without pay or at a discount in accordance with an embodiment of the present invention, and Fig. 3 shows a schematic view illustrating a procedure for schematically illustrating a service for transmitting an originating message of a mobile terminal to a destination terminal without pay or at a discount in accordance with an embodiment of the present invention.

Referring to Fig. 2, a communication system for an originating message transmission service for free or discount includes the mobile network 10, a public network 16 such as a public switched telephone network (PSTN) and a packet switching public data network, and an Internet protocol (IP) network 28. The mobile network 10 including a base station (BS) 12 and the mobile switching center 14 establishes wireless communication with the mobile terminal 2 and is connected to an originating message transmission service apparatus 20. In addition, the public land mobile network 10 is connected to the public network 16. Furthermore, the mobile network 10 is connected to the IP network 28 although a direct connection between them is not shown in Fig. 2. A wired information terminal 18 is connected to the public network 16, and user terminals 20 and 32 such as a personal computer or a notebook computer are connected to the IP network 28. The originating message transmission service apparatus

20, which is connected respectively to the mobile network 10, the public network 16 and the IP network 28, receives the originating message transmitted from the user of the mobile terminal 2 via the mobile network 10, and transmits the received originating message to the called party terminal 6 of Fig. 1, for example, the wired information terminal 18 or the user terminals 30 and 32 of Fig. 2 while transmitting the repayment advertisement message for the message transmission to the advertisement receipt terminal (e.g., the called party mobile terminal 2) . The originating message transmission service apparatus 20 includes the transfer server 4, a voice announcement unit 22, a user information DB (database) 24 and an advertisement DB 26.

Fig. 3 shows a schematic view illustrating a procedure schematically illustrating a service for transmitting an originating message of a mobile terminal to a destination terminal without pay or at a discount in accordance with an embodiment of the present invention, and Figs. 4 to 6 are flow charts for a control in a transfer server 14 in accordance with an embodiment of the present invention. In more detail, Fig. 4 is a flow chart for an operation control for a service for transmitting an originating message of a calling party mobile terminal to a called party mobile terminal without pay or at a discount, Fig. 6 is a flow chart for a control for advertisement remaining transmission process, and Fig. 7 is a flow chart for a control for a use history process for an advertisement acknowledgement response .

Hereinafter, referring to Figs. 1 to 6, the operation of the originating message transmission service for free or discount in accordance with an embodiment of the present invention will be described in detail.

Although a message originated from the mobile terminal is mainly a short message service (SMS) at present, it is expected that complex messages including voice and images as well as the text will be used in the future and, accordingly, packet capacity for the complex messages will be increased. Keeping pace with this increase in packet capacity, according to the embodiment of the present invention, a mobile terminal user can transmit an originating message such as text, voice and images to the other persons without pay or at a discount.

When a mobile terminal user attempts to transmit an originating message such as text, voice and images to the other persoii without pay or at a discount, he can request an originating message transmission service for free or discount to the originating message transmission apparatus 20 using his own mobile terminal 2. At this time, using a user interface with the calling party mobile terminal 2, the user inputs an originating message free or discount transmission request code to the calling party mobile terminal 2 such that an originating message free or discount transmission request is identified by the mobile network 10 (Step 100 in Fig. 3), inputs a called party terminal number of the other person (Step 102 in Fig. 3) , and inputs an identification number (for example, telephone number) at which an advertisement is to be received (Step 104 in Fig. 3) . Next, the user inputs contents (text, voice, images, etc.) of the message to be transmitted to the other person (Step 106 in Fig. 3) and then transmits an originating message transmission request (Step 108 in Fig. 3) . As the telephone number at which the advertisement is to be received, an identification number of the calling party mobile terminal 2 is typically input as a default value, but alternatively, a different identification number may be input. If a different identification number (or a terminal identifier number) is input as the identification number at which the advertisement is to be received, since the advertisement is transmitted to the input different identification number, there is a convenience in that the user can select a terminal through which the advertisement may be easily and conveniently viewed. When the user makes a request for the originating message transmission using a key input of the calling party mobile terminal 2, at Step 110 of Fig. 3, the calling party mobile terminal 2 transmits a mobile terminal originating message including the free or discounted message transmission request code, the called party terminal number, the advertisement receipt identification number, the contents of the message, and a mobile terminal identifier number to the base station 12 of the mobile network 10 wirelessly, and then the base station 12 of the mobile network 10 transmits the received mobile terminal originating message to the mobile switching center 14. At Step 112 of Fig. 3, the mobile switching center 14 of the mobile network 10 checks and validates the originating free or discounted message transmission request code, and then, if the code is valid, the mobile terminal originating message is transmitted to the transfer server 4 of the originating message transmission service apparatus 20.

When the transfer server 4 of the originating message transmission service apparatus 20 receives a request for the originating message free or discount service, it transmits the mobile terminal originating message to the called party terminal 6 without pay or at a discount at Step 116 of Fig. 3, and then, transmits a repayment advertisement message for the transmission of the mobile terminal originating message without pay or at a discount, to a terminal (e.g., the calling party mobile terminal of Figs. 1 and 2) corresponding to the advertisement receipt identification number included in the mobile terminal originating message at Step 118 of Fig. 3. A detailed procedure of Steps 116 and 118 of Fig. 3 will now be described with reference to Fig. 4. Referring to Fig. 4, the transfer server 4 of the originating message transmission service apparatus 20 determines at Step 200 of Fig. 4 whether the originating free or discounted message transmission request code is present in the mobile terminal originating message transmitted from the calling party mobile terminal 2. If it is determined that the code is present, the transfer server 4 recognizes that there is a request for the originating message free or discount service, and then, determines at Step 202 of Fig. 4 whether the mobile terminal originating message is normal. Namely, it is checked on whether a message transmission error is present or not. If the mobile terminal originating message is not normal, the transfer server 4 transmits a voice announcement message informing the calling party mobile terminal 2 of the message error at Step 206. However, if the mobile terminal originating message is normal, the transfer server 4 checks the terminal identifier number included in the mobile terminal originating message at Step 204 of Fig. 4. The terminal identifier number is a number uniquely granted to each terminal. Next, it is determined at Step 208 of Fig. 4 whether the terminal identifier number is a new number using the user information DB 24. If the terminal identifier number is a new number not registered in the user information DB 24, in association with other communication network switching centers, the transfer server 24 checks at Step 216 whether the terminal identifier number is a terminal identifier number with which the originating message transmission service for free or discount is available. This check is a measure for confirming if a previous accumulatively warned user has changed his existing terminal identifier number and has been endowed with a new terminal identifier number. Next, it is determined at Step 218 whether the checked terminal identifier number is a terminal identifier number with which the originating message transmission service for free or discount is available without pay. If the checked terminal identifier number is a terminal identifier number with which the originating message transmission service for free or discount is available without pay, the process proceeds to Step 219 of Fig. 4 where a message informing that the originating message transmission service for free or discount is not available is transmitted to the calling party mobile terminal 2.

On the contrary, if it is determined at Step 218 of Fig. 4 that the checked terminal identifier number is a terminal identifier number with which the originating message transmission service for free or discount is available without pay, the process proceeds to Step 220 of Fig. 4. The transfer server 4 checks the form (text, voice, image, etc.) and capacity of the contents of the message included in the received mobile terminal originating message at Step 220 of Fig. 4, and then transmits the mobile terminal originating message to the called party terminal 6 without pay or at a discount at Step 222 of Fig. 4. Namely, a user of the calling party terminal 2 receives a benefit, such as no charge or a discount, from the originating message transmission service apparatus 20 when the mobile terminal message is transmitted. The benefit such as no charge or a discount can be implemented in various ways depending on the kind of system to which the present invention is applied. In other words, an amount of the benefit such as no charge or a discount to be provided to the user may be defined depending on the kind of the originating message, the kind of the repayment advertisement, the number of times of advertisement transmission, etc. For example, if the originating message is a short message and the repayment advertisement is also a short message, a discount benefit may be granted to the user of the calling party mobile terminal 2 after the advertisement is provided to the user several times. The called party terminal 6 can be the wired information terminal 18 or the user terminals 30 and 32 as shown in Fig. 2, for example, or alternatively, can be a mobile terminal (not shown in the drawings) being a subscriber of the public land mobile network 10.

Next, the process proceeds to Step 224 of Fig. 4 where the transfer server 4 selects from the advertisement DB 26 a repayment advertisement to be transmitted to the advertisement receipt terminal (e.g., the calling party mobile terminal 2) and determines the number of times of advertisement transmission, depending on the form and capacity of the checked originating message. The repayment advertisement may be a simple character advertisement or a still image advertisement. Alternatively, the repayment advertisement can be a moving picture advertisement. Next, the process proceeds to Step 226 of Fig. 4 where the transfer server 4 transmits the repayment advertisement to the calling party mobile terminal 2. A number for advertisement acknowledgement generated by the transfer server 4 is included at the end of the repayment advertisement. After performing Step 226 of Fig. 4, the transfer server 4 stores information related to the repayment advertisement in the user information DB 24 at Step 228 of Fig. 4. On the other hand, at Step 208 of Fig. 4, if it is determined that the terminal identifier number is not a new number, the transfer server 4 of the originating message transmission service apparatus 20 proceeds to Step 210 of Fig. 4. At Step 210 of Fig. 4, the transfer server 2 accesses the user information DB 24 in order to check on whether warning accumulation and accumulated number of warnings to a user corresponding to the terminal identifier number are present. At Step 212 of Fig. 4, the transfer server 2 determines whether the accumulated number of warnings exceeds a predetermined threshold value. If the accumulated number of warnings does not exceed the predetermined threshold value, the process proceeds to Step 220 of Fig. 4. If the accumulated number of warnings exceeds the predetermined threshold value, the process proceeds to Step 214 of Fig. 4. At Step 214 of Fig. 4, the transfer server 4 of the originating message transmission service apparatus 20 transmits the advertisement to the advertisement receipt terminal (e.g., the calling party mobile terminal 2) once again, informing that the accumulated number of warnings exceeds the predetermined threshold value. A newly generated number for advertisement acknowledgement is included at the end of the re-transmitted advertisement.

Referring to Fig. 3 again, after transmitting the mobile terminal originating message to the called party terminal 6 without pay or at a discount and then transmitting the repayment advertisement message to the calling party mobile terminal 2, the transfer server 4 performs a transmission process control for remaining repayment advertisements at Step 120 of Fig. 3. The number of times of advertisement transmission is varied depending on whether the advertisement is a short message service advertisement, a still image advertisement or a moving picture advertisement. It is preferable that the advertisement receipt terminal is notified of the number of times of advertisement transmission through an announcement note or an announcement message such that the advertisement receipt terminal knows the number of times of advertisement transmission well in advance.

Hereinafter, the transmission process for the remaining advertisements, which is performed at Step 120 of Fig. 3, will be described in detail. Referring to Fig. 5, the transfer server 4 of the originating message transmission service apparatus 20 searches a list of advertisement transmission targets in the advertisement DB 26 periodically at Step 304 of Fig. 5 and determines at Step 306 of Fig. 5 whether a transmission target identification number (for example, telephone number) is present. If a transmission target identification number is present, the process proceeds to Step 308 of Fig. 5. At Step 308 of Fig. 5, the transfer server 4 accesses the user information DB 24 in order to determine whether the advertisement receipt terminal (e.g., the calling party mobile terminal 2) has made an advertisement acknowledgement response to a previously transmitted advertisement. The advertisement acknowledgement response is made by a user inputting the advertisement acknowledge number attached at the end of the previous transmitted advertisement to his own calling party mobile terminal 2 after acknowledging the advertisement and the input advertisement acknowledgement number is transmitted to the transfer server 4.

If it is determined at Step 308 of Fig. 5 that the advertisement receipt terminal has made an advertisement acknowledgement response to the previously transmitted advertisement, the transfer server 4 proceeds to Step 310 of Fig. 5. The transfer server 4 generates a new advertisement acknowledgement number at Step 310 of Fig. 5 and transmits the newly generated advertisement acknowledgement number and a corresponding advertisement to the advertisement receipt terminal (e.g., the calling party mobile terminal 2) at Step 312 of Fig. 5.

On the other hand, if it is determined at Step 308 of Fig. 5 that the advertisement receipt terminal has not made an advertisement acknowledgement response to the previously transmitted advertisement, the transfer server 4 proceeds to Step 314 of Fig. 5, where the accumulated number of warnings is incremented by "1". After this, the process proceeds to Step 316 of Fig. 5, where the transfer server 4 determines whether the accumulated number of warnings exceeds a predetermined threshold value. If the accumulated number of warnings does not exceed the predetermined threshold value, the process proceeds to Step 310 of Fig. 5, where the corresponding above-described operation is performed. If the accumulated number of warnings exceeds the predetermined threshold value, the process proceeds to Step 318 of Fig. 5. The transfer server 4 increments the accumulated number of warnings by "1" at Step 318 of Fig. 5 and determines at Step 329 of Fig. 5 whether the accumulated number of habitual warnings exceeds a certain threshold value. If it is determined at Step 320 of Fig. 5 that the accumulated number of habitual warnings exceeds a certain threshold value, the transfer server 4 transmits a warning message indicating stoppage of the mobile terminal originating message transmission service for free or discount to the calling party mobile terminal 2 and changes corresponding user information included in the user information DB 24 such that the mobile terminal originating message transmission service for free or discount is stopped.

Referring to Fig. 3 again, the user of the calling party mobile terminal 2 can use the mobile terminal originating message transmission service for free or discount preferentially one time, and simultaneously, receives the repayment advertisement message if the calling party mobile terminal 2 is the advertisement receipt terminal. When the user who received the repayment advertisement message confirms the advertisement in his own calling party mobile terminal 2 and inputs the advertisement acknowledgement number attached to the end of the advertisement (Step 122 of Fig. 3) , the advertisement acknowledgement number is transmitted from the calling party mobile terminal 2 to the transfer server 4 as shown in Step 124 of Fig. 3.

Upon receiving the advertisement acknowledgement number from the calling party mobile terminal 2 which is the advertisement receipt terminal, the transfer server 4 of the originating message transmission service apparatus 20 performs a user history process according to the advertisement acknowledgement response, as shown in Step 126 of Fig. 3. Hereinafter, the operation of the transfer server 4 for performing the user history process according to the advertisement acknowledgement response will be described in detail with reference to Fig. 6.

The transfer server 4 of the originating message transmission service apparatus 20 determines at Step 400 of Fig. 6 whether the advertisement acknowledgement number is received from the calling party mobile terminal 2 which is the advertisement receipt terminal and then, if the advertisement acknowledgement number is received, accesses the user information DB 24 in order to check on whether the warning accumulation for the calling party mobile terminal which transmitted the advertisement acknowledgement response is present. After this, it is determined at Step 406 of Fig. 6 whether the warning accumulation is present. If the warning accumulation is present, the accumulated number of warnings is decremented by "1" at Step 408 of Fig. 6 and the number of remaining advertisements is decremented by "1" at Step 410 of Fig. 410. On the contrary, if it is determined at Step 406 of Fig. 6 that there is no warning accumulation, the process proceeds to Step 410, where the number of remaining advertisements is decremented by "1".

After performing Step 410 of Fig. 6, the transfer server 4 determines at Step 412 of Fig. 6 whether the number of remaining advertisements is "0", and then, if the number of remaining advertisements is "0", proceeds to Step 414 of Fig. 6, where user terminal information related to the originating message transmission service for free or discount is deleted from the user information DB 24. On the contrary, if it is determined at Step 412 of Fig. 6 that the number of remaining advertisements is not ^N0", the process is ended. On the other hand, if it is determined at Step 400 of Fig. 6 that the advertisement acknowledgement number is not received, the transfer server 4 proceeds to Step 402 of Fig. 6, where an advertisement acknowledgement request message is periodically transmitted to the calling party mobile terminal 2 which is the advertisement receipt terminal.

Although it has been described in the embodiment of the present invention that the transfer server 4 provides an advertisement to an advertisement receipt terminal (e.g., the calling party mobile terminal 2) one-sidedly, it is apparent to those skilled in the art that the present invention is configured such that a user of the calling party mobile terminal 2 which is the advertisement receipt terminal can confirm the advertisements at a convenient time specified by the user.

As apparent from the above description, according to the present invention, a user can have a benefit to save all or some of the costs required when an originating message such as text, voice or an image is transmitted, and an advertiser can advertise more stably and effectively, compared to a random advertisement to many and unspecified persons, by transmitting a repayment advertisement to users attempting to use an originating message transmission service for free or discount by means of a transfer server.

Industrial Applicability The present invention is applicable to a service for allowing a mobile terminal to transmit a message without pay or at a discount in a mobile communication system.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Therefore, it should be understood that the scope of the present invention should be defined by the accompanying claims and the equivalents thereof, not the illustrated embodiments.
