Description

Communication apparatus and method for controlling the retransmission of a message {Communication apparatus and method for controlling re-transmitting a message}

The present invention relates to a communication apparatus and a method for controlling the retransmission of a message for controlling the retransmission of the message, and more particularly, a message for determining whether or not to retransmit the message by inserting control data for controlling whether or not retransmission is possible to the message A communication apparatus and method for controlling retransmission of an apparatus are provided.

In recent years, the mobile communication terminal is provided with a variety of services provided by the mobile communication provider in addition to the call service. Among them, a message transmission service is the most used service of mobile subscribers.

The message transmission service is the second most used service after the call service in that it does not transmit information by setting up a voice call, but can easily perform an information transmission function. In some cases, a message service is preferred to a call service, and a text service fee is charged more than a communication service fee.

The problem is that information delivered using the message service is likely to be stored in the receiving mobile communication terminal and retransmitted to a third party.

That is, the conventional message is defined as a text message having a size of 80 bytes to 90 bytes, but the current message includes a multimedia message including multimedia data such as pictures, audio, and video. These multimedia messages allow senders to send more of their personal information without foreseeing it being delivered to third parties.

For example, when a user composes and sends a picture taken by a user's mobile terminal to a friend, the friend may have a possibility to resend the message to another person. That is, it can be transmitted and distributed to others through the function of transmitting the received message to a third party as it is.

However, the user may want the picture to be retransmitted to someone other than a friend, but the prior art could not prevent the recipient of the message from retransmitting the message only by sending the message.

In addition, a mobile communication service provider needs to block retransmission of a message when providing a so-called web to phone multimedia message service that is unilaterally transmitted through a wired or wireless web server.

For example, a mobile communication service provider or a separate message transmission service provider may transmit securities information to a terminal of a web to phone multimedia message service subscriber through the web. However, since the subscriber pays a certain amount monthly and receives the securities information service, if the securities information is spread to terminals other than the subscriber, it may cause a big obstacle in profits.

However, in the related art, there is no means for preventing a message such as stock information from being re-transmitted from a terminal of a web-to-phone multimedia message service subscriber to an arbitrary third terminal, and thus a paid service such as stock information, even though it is not a service subscriber. There was a problem that can be used free of charge.

It is an object of the present invention to provide a communication apparatus and method for controlling the retransmission of a message by inserting control data into the message and transmitting the same.

Another object of the present invention is to provide a communication apparatus and method capable of receiving a message in which control data is inserted and determining whether to retransmit the message using the control data.

Still other objects of the present invention will become more apparent from the detailed description for carrying out the invention described below.

According to an aspect of the present invention, a message retransmission control method is provided.

A retransmission control method is provided.

According to another embodiment of the present invention, a method for controlling retransmission of a message in a mobile communication terminal, the method comprising: receiving the message through a mobile communication network, wherein the message includes control data for controlling retransmission of the message box-; Determining whether retransmission of the message is possible using the control data included in the received message when receiving a retransmission command of the received message; And retransmitting the message to another mobile communication terminal when retransmission of the message is possible as a result of the determination.

According to another aspect of the present invention, a communication device is provided.

According to an embodiment of the present invention, in a communication device for controlling retransmission of a message, a message to which a control data is inserted is transmitted to a receiving mobile communication terminal through a mobile communication network or a transmission request to a message transmission device interworking with the mobile communication network.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The communication device for controlling the retransmission of a message of the present invention includes a communication terminal such as a mobile communication terminal, a personal computer (PC), a personal digital assistant (PDA), as well as a message transmission device such as a message center or a message transmission server. I understand. Hereinafter, each communication device will be described in detail for convenience of description for each drawing, but the configuration of the communication device and the method for controlling the retransmission of a message described in each drawing are described in any one of the above-described communication terminal or message transmission device. It is not limited.

1 is a diagram showing the configuration of a message transmitted according to an embodiment of the present invention.

Referring to FIG. 1, the message includes an HTTP header 110, a service parameter 120, a service 130, an HTML 130, a content 1 header 140, a content 1 150, a content 2 header 160, and a content 2. It is composed of 170 areas.

The configuration of the message of Figure 1 is an example of a message structure for explaining an embodiment of the present invention, it is obvious that the configuration of the message can be variously expressed according to the description method.

The HTTP header 110 defines information such as message transmission time, transmission mobile communication terminal number, callback number, title, content type, and message length.

The HTML 130 region is a part defining the structure of the message, and is expressed using each tag so that the terminal browser can analyze and construct the structure of the message, similarly to the HTML document recognized by a general web browser. Content such as an image, voice, or video to be expressed in the structure represented by the HTML 130 area is designated through an identifier (CID: Content ID) for identifying each of the contents to be described later.

In the present specification, for convenience of description, the markup language is described as HTML, but the markup language is not limited thereto, and the message transmitted by the mobile communication terminal of the present invention is a message in the form of Synchronized Multimedia Integration Language (SMIL). Can be replaced with XML (eXtensible Markup Langauge). SMIL is used to create multimedia presentations by combining audio, video, text, and graphics. It is a comprehensive language for XML-based multimedia consisting of several simple TAGs and attributes. It's a language that provides a mechanism to synchronize location and time to present. However, even in the case of a SMIL format message, the configuration of the message of FIG. 1 does not depart.

In the content 1 header 140, the ID of the content 1 150, the type of the content 1 150, the encoding method of the content 1 150, and the like are defined, and the content 1 150 defined in the content 1 header 140 is defined. The data is included in the content 1 150 area. The content 1 150 may be one or more of data such as an image, text, voice, and flash. Since the ID of the content 1 150 is specified inside the HTML 130 as described above, the content 1 130 is represented in the structure defined by the HTML 130 on the display of the mobile communication terminal receiving the message.

The content 2 header 160 and the content 2 170 region also include data for the content 2 as in the case of the content 1.

The service parameter 120 area is an area that contains additional information necessary for message transmission and does not affect the transmission of the message. However, it may include a message class required for a mobile communication terminal to receive and store a message and store it in a database, a priority used to indicate a priority of the message, and various billing information.

However, the service parameter 120 is only one example for describing the present patent. The message class required for the mobile communication terminal, the priority used to indicate the message rank, various billing information, and the like are the HTTP header 110, Obviously, it may be included in any of the content 1 header 140, the content 1 150, the content 2 header 160, or the content 2 170.

The mobile communication terminal corresponding to the communication device according to an embodiment of the present invention may insert control data into the service parameter 120 area. The control data is data for controlling the retransmission of the message and is data indicating whether it is possible to retransmit the message to another mobile communication terminal in the mobile communication terminal receiving the message.

In the present specification, retransmission of a message is performed by the receiving mobile communication terminal receiving a message transmitted by the transmitting mobile communication terminal rather than transmitting the same message to the same receiving mobile communication terminal several times. It means forwarding a message to a mobile communication terminal.

The control data may be defined in various formats as set in advance. Hereinafter, the control data will be defined and described as "forwarding" for convenience of description.

The control data may be expressed as <Forwarding: Yes> or <Forwarding: No> and included in the above-described service parameter 120 area. <Forwarding: Yes> means that retransmission of the message is impossible in the receiving mobile communication terminal and <Forwarding: No> means that retransmission of the message is possible in the receiving mobile communication terminal.

Even if the control data is not inserted into the message, it does not affect the process of transmitting the message to the receiving mobile communication terminal through the mobile communication network. Therefore, the user of the mobile communication terminal can directly input and input the control data.

Alternatively, the mobile communication terminal may be set to display a screen for querying whether to insert control data when the message is written, and may be set to always insert <Forwarding: Yes> or <Forwarding: No> into the message.

The configuration of the mobile communication terminal inserting the above-described control data will be described in detail with reference to FIG. 3A.

The control data may not only be inserted in the mobile communication terminal but also may be inserted in a message center such as a short message center or a multimedia message center included in the mobile communication system. That is, when a message without control data inserted from the mobile communication terminal is uploaded to the message center, the control center may insert control data into the message.

Therefore, the user of the transmitting mobile communication terminal may insert the control data in the message center so that the message is transmitted without performing a separate control data insertion process in the transmitting mobile communication terminal.

In addition, when a mobile communication service provider or a separate message transmission provider provides a web-to-phone multimedia message service while operating a separate message transmission server, control data may be inserted into a message. Web-to-phone multimedia message service is a free or paid service that a mobile communication service provider or a message transmission operator generates information such as weather, securities, and traffic into a message and transmits it to a mobile communication terminal via a mobile communication network.

Therefore, it is possible to control retransmission of the message by inserting control data into a message such as weather, stocks, traffic, etc. in advance so that the mobile communication terminal that receives the message cannot transmit the message to the third mobile communication terminal.

In addition, a mobile communication service subscriber accesses a message transmission server using a communication terminal such as a personal computer (PC), a notebook computer, a personal digital assistant (PDA) as well as a mobile communication terminal, and transmits a message created in the communication terminal to the message transmission server. By requesting, the message can be transmitted to the receiving mobile communication terminal. Even in this case, if the message corresponds to personal information, the control data needs to be inserted because it is necessary to control the retransmission of the message.

In this case, a message transmission server may provide a user interface for inserting control data after directly writing a message in a communication terminal. Alternatively, the message transmission server may directly insert retransmission data into the message requested for transmission from the communication terminal.

The configuration of the message transmission apparatus corresponding to the above message center or message transmission server will be described later with reference to FIG. 3B.

2 is a view showing in detail a message transmitted by an embodiment of the present invention.

Referring to FIG. 2, the message includes the HTTP header 110, the service parameter 120, the HTML 130, the content 1 header 140, the content 1 150, the content 2 header 160, except for the service parameters. In this case, a message including contents 1 and 2 (150, 170) may be displayed at a receiving terminal through a mobile communication network.

That is, the reception mobile communication terminal that receives the message of FIG. 2 is outputted from the "World Cup Stadium" included in the HTTP header 110, and the content ID myimage.jpg is included in the body defined by the HTML 130. 150 is displayed, and as the background music, content 2 170 having content ID mysound.nsnd is output as voice. Here, myimage.jpg and mysound.nsnd are identifiers of the content 1 150 and the content 2 170, and each content is converted into ASCII text and included in the content area. The encoding method is defined in each content header. The content header of FIG. 2 may be defined as Content-Transfer-encoding: base 64.

However, it is not possible to determine whether the message received by the receiving mobile communication terminal can be retransmitted to another mobile communication terminal separately from whether the message received by the receiving mobile communication terminal can be normally expressed.

That is, in the related art, a message received by a receiving mobile communication terminal can be transmitted to another mobile communication terminal without any limitation.

Therefore, the message sender was hesitant to transmit a message that he did not want to spread personally. For example, the message of FIG. 2 may be a message transmitted to the terminal of the mobile communication of the best friend by adding background music to his photo taken at the World Cup stadium. In this case, the sender of the message only wants the best friend to keep the picture, but not the other person. However, the way to control the transfer of photos from your best friend's mobile device to someone else's mobile device is to enter a separate text that says 'Don't send the picture to someone else,' or send a call directly. Do not send it to anyone. "

However, despite this notification, if the best friend sent the picture to someone else's mobile terminal, there was no way to control it. This was the case when the message sender uses a mobile communication terminal, a message transmission, or a web-to-phone multimedia message service using a terminal such as a PC.

According to an embodiment of the present invention, a mobile communication terminal corresponding to a communication terminal, a communication terminal such as a PC, a message center, or a message transmission server inserts and transmits control data of a message into a message, thereby not creating text separately as described above. It is possible to control that a message including a picture is not transmitted from a receiving mobile communication terminal to another mobile communication terminal.

That is, when <Forwarding: No> is inserted into the service parameter 120 area between the HTTP header 110 and the HTML 130 in the transmitting mobile communication terminal as shown in FIG. 2, the receiving mobile communication terminal receiving the message < Forwarding: At No>, it can be determined that retransmission of the message is not allowed. However, as described with reference to FIG. 1, control data may be inserted in other communication terminals such as a PC or a message transmission device such as a message center or a message transmission server.

Therefore, when a user of a receiving mobile communication terminal inputs a transmission command to transmit a received message to another mobile communication terminal, a message indicating that transmission of the corresponding message is not allowed may be output to the receiving mobile communication terminal.

According to another embodiment of the present invention, parameters indicating whether retransmission is possible for each content may be inserted into the service parameter 120 area. That is, the content 1 (150) having the content ID myimage.jpg is content that does not want to be retransmitted, and the content 2 (170) having the content ID mysound.nsnd (the background music) may be content irrelevant even if retransmitted. In this case, a <Forwarding> parameter indicating whether to retransmit is inserted into the service parameter area, such as <myimage.jpg: Forwarding: No>, or an additional <Forwarding> parameter may be inserted into the header 140 of the content object that is myimage.jpg. .

In this case, since only myimage.jpg is not desired to be retransmitted, if the edit to delete myimage.jpg is made in the receiving mobile communication terminal, the content corresponding to <Forwarding: No> is deleted, so retransmission is allowed.

3 is a diagram illustrating a configuration of a transmitting mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 3, the transmission mobile communication terminal 300 includes an antenna 310, an RF unit 320, a base band processor 340, and an input unit 370. Although not shown in FIG. 3, it is obvious that the display unit, the speaker, or the camera may be further included in the mobile communication terminal, and a description thereof will be omitted.

In the present specification, the transmitting mobile communication terminal 300 refers to a mobile communication terminal on the side of transmitting a message, and the receiving mobile communication terminal refers to a mobile communication terminal receiving a message from the transmitting mobile communication terminal.

The antenna 310 transmits a radio signal from the transmitting mobile communication terminal 300 to the mobile communication network or receives a radio signal transmitted from the mobile communication network. In FIG. 3, a message generated by the transmitting mobile communication terminal 300 is converted into a radio frequency band and described as a function of an antenna, which is a passage for transmitting to a mobile communication network.

The RF unit 320 amplifies and converts various data processed by the baseband processor 340 to a radio frequency band and transfers the data to the antenna 310, so that a duplexer and a power amplifier are not shown in FIG. 3. It will be apparent to those skilled in the art that a power amplifier (PA) may further include an internal oscillator for generating a frequency of a commercial channel, a SAW filter for passing only a frequency signal of a service band, and the like. The RF unit 320 shown in FIG. 3 includes a message transmitter 330. The message transmitter 330 transmits a message generated at the baseband level by the baseband processor 340 to a carrier frequency and transmits the same through an antenna. It performs the function.

The baseband processor 340 includes a controller 350 and a storage 360. The control unit 350 not only controls the general operation of the components included in the transmitting mobile communication terminal 300, but further includes a message generating unit 350 for generating a message according to a command input by the user through the input unit 370. Include. In FIG. 3, the message generator 351 is shown as a logical component in which one or more microprocessors are operated by a program stored in the storage 360, but may be performed by a logic operation module composed of a separate microprocessor.

In addition, the control unit 350 further includes a control data inserting unit 359, which corresponds to a logical component for inserting control data into a message generated by the message generating unit 351. The control data insertion unit 359 inserts <Forwarding: NO> or <Forwarding: Yes> into the service parameter area of the generated message as described with reference to FIGS. 1 and 2. The control data inserting unit 359 is set to insert <Forwarding: NO> in advance, and may output a question to the display unit (not shown) of the transmitting mobile communication terminal 300 to allow retransmission. That is, it may be set to insert <Forwarding: Yes> only when the user of the transmitting mobile communication terminal 300 inputs "Yes" to the output question.

The input unit 370 is composed of a keypad, a touch pad, and the like, which allows a user to input a performance command to the transmitting mobile communication terminal 300, and may be integrally formed with the display.

The storage unit 360 may be composed of SDRAM, NAND FLASH, and the like, and stores various data such as a call processing program, a message font, a system parameter, and the like.

The storage unit 360 of the transmitting mobile communication terminal 300 of the present invention stores a message program for causing the control unit 350 to perform the functions of the message generator 351 and the control data insertion unit 359. The content inserted into the generated message is stored. That is, content 1, which is the photo content described in FIG. 2, and content 2, which is the background music content, are stored.

3B is a diagram showing the configuration of a message transmission apparatus and a communication system according to an embodiment of the present invention.

Referring to FIG. 3B, the communication system includes an MSC 380, a message transmission server 382, an MMSC 385, a communication terminal 384, a base station 386, and a receiving mobile communication terminal 390. In FIG. 3B, the message transmission device should be understood to include a message transmission server and an MMSC.

MSC (380) (Mobile Switcing Center) is a network constituent device that performs pivotal functions in mobile communication network. It is a wired / wireless digital exchange that provides wired communication, wireless communication function and mobile communication function. Function, location registration procedure of mobile communication terminal, handoff procedure processing and interworking function with other network.

The base station 386 is a mobile communication network terminator that is directly connected to a mobile communication terminal by performing baseband signal processing, wired / wireless conversion, and transmission and reception of a wireless signal.

MMSC 385 (Multimedia Message Service Center) receives and stores a message from a transmitting mobile communication terminal (not shown), and caching (Caching) to allow the receiving mobile communication terminal 390 to access the MMSC 385 to receive a message. Perform the function. In addition, it performs pre-paid, reply charging, message blocking, and integrated messaging through interworking with VMS (Voice Mail Sever) and external e-mail server (not shown). The MMSC 385 according to an embodiment of the present invention inserts control data into a message received from a transmitting mobile communication terminal (not shown) to the receiving mobile communication terminal 390 through the MSC 380 and the base station 386. Can transmit

That is, when the message is transmitted without the control data inserted in the transmitting mobile communication terminal which does not insert the control data in the message unlike the transmitting mobile communication terminal described in FIG. 2, the MMSC 385 inserts the control data into the message. It can transmit to the receiving mobile communication terminal.

To this end, the MMSC 385 according to an embodiment of the present invention may include a message receiver 385a, a control data inserter 385b, and a message transmitter 385c. When the transmitting mobile communication terminal uploads the mesh to the MMSC 385, the controller (not shown) of the MMSC 385 may determine whether a <Fowarding> parameter exists in the service parameter region described with reference to FIG. 2.

If control data such as a <Fowarding> parameter does not exist, the control data insertion unit 385b may insert the control data into the message.

The message transmitter 385c may control the retransmission of the message by transmitting the control data-inserted message to the receiving mobile communication terminal 390 through the MSC 380 and the base station 386.

The message transmission server 382 is a server interworking with the mobile communication network through the IP communication network, and thus is connected to the IP communication network, so that the message transmission server 382 can communicate with not only a mobile communication terminal but also a communication terminal such as a PC. The message transmission server 382 is connected to the Internet network and the Packet Data Service Node (PDSN) through the MSC 380 and the Interworking Function (IWF). Accordingly, data such as a message may be transmitted to the receiving mobile communication terminal 390 through the MSC 380 and the base station 386.

The message transmission server 382 may be a server operated by a mobile communication service provider, or may be a server operated by a separate message transmission provider or another mobile communication service provider.

The message transmission server 382 includes a message generator or receiver 382a and further includes a control data inserter 382b and a message transmitter 382c. In FIG. 3B, the message generating / receiving unit is described. Hereinafter, for convenience of explanation, the message generating unit and the message receiving unit are separated and described using the same identification number 382a.

The message generator 382a may generate a message including information on weather, securities, and traffic. Messages containing such information need to be prevented from being re-transmitted from the receiving mobile communication terminal 390 to another third mobile communication terminal due to problems such as copyright or information usage fee.

The message receiving unit 382a connects to the message transmitting server 382 through a communication terminal 384 such as a PC and requests to transmit a message created by a message writing application installed on the PC 384 to the receiving mobile communication terminal 390. Performs a function with receiving. Even in this case, it is necessary to prohibit unauthorized retransmission from the receiving mobile communication terminal 390 to another third mobile communication terminal due to a problem such as personal information infringement.

Accordingly, the control data inserting unit 382b inserts control data into a message generated by the message generating unit 382a or a message received by the message receiving unit 382a.

The message transmitter 382 c makes a message transmission request to the MSC 380 through the IP communication network. The control data-inserted message is transmitted to the receiving mobile communication terminal 390 via the base station 386.

Accordingly, as described above, the MMSC 385 and the message transmission server 382 may insert control data into a message and transmit the control data to the receiving mobile communication terminal 390, respectively, and the MMSC 385 or the message transmission server 382 may transmit the message. Corresponds to a message transmission apparatus capable of performing each function depending on whether it is a phone to phone multimedia message service or a web to phone multimedia message service.

4A is a flowchart illustrating a process of transmitting a message in a transmitting mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 4A, the transmitting mobile communication terminal 300 receives a multimedia message preparation input according to a user's input (S400). The multimedia message writing input may be sequentially configured by inputting to select content stored in the storage 360, input for writing text, and input for confirming a completed message. In FIG. 4, the multimedia message will be described. However, the present invention can be applied to a short message and can be equally applied to the creation of a SMIL-type multimedia message.

After receiving the multimedia message composition input, the transmitting mobile communication terminal 300 may output a screen to the display of the transmitting mobile communication terminal 300 inquiring whether to allow the message to be retransmitted. However, if it is set as a default value for whether to allow retransmission in advance, it may proceed to step S420 or step S430 to be described later without asking whether to allow retransmission.

If the user selects "No", <Forwarding: NO> is inserted into the service parameter area of the multimedia message (S420). If "Yes" is selected, <Forwarding: Yes> is inserted (S430). As described above, when it is set as a default value for whether to allow retransmission, for example, when <Forwarding: NO> is set as a default value, step S410 may be omitted and step S420 may be immediately performed.

Alternatively, if the user does not select "Yes" or "No", the <Forwarding> value may be omitted in the service parameter area. Since the service parameter area includes additional information, the message transmission has no effect and the <Forwarding> value can be omitted. If the value of <Forwarding> is omitted, a conventional method for retransmission of a message may be applied, and thus the message may be transmitted without limitation. This will be described in detail later with reference to FIG. 7.

When the process of step S420 or step S430 is completed, the transmitting mobile communication terminal 300 transmits the created multimedia message to the receiving mobile communication terminal through the mobile communication network (S440).

4B is a flowchart illustrating a message transmission method of a transmitting mobile communication terminal according to another embodiment of the present invention.

Referring to FIG. 4B, the process of step S400 and step S410 of receiving a multimedia creation input from the transmitting mobile communication terminal and asking the user whether retransmission is possible is the same as described with reference to FIG. 4A.

In FIG. 4A, <Forwarding: Yes> or <Forwarding: NO>, which is identification information indicating whether retransmission is possible based on a message or content, is inserted.

However, according to another embodiment of the present invention, the transmitting mobile communication terminal may allow or prohibit retransmission of the message based on the mobile communication terminal to receive the retransmission message. For example, company A has an electronic team, a mechanical team, and a chemical team, among which a team leader wants to send important team information to team members in a multimedia message. That is, security information that should not be leaked to a team other than the electronic team may correspond to this.

In this case, the team leader of the electronic team may instruct the team leader to retransmit the message including the team information through the mobile communication terminal to the team leader's mobile communication terminal. However, the vice-chairman may mistakenly enter the member of the mechanical team with the number of the receiving mobile communication terminal, and the team information may be leaked to the mechanical team.

However, according to the mobile communication terminal according to an embodiment of the present invention, when the team leader instructs the second team leader to retransmit to the mobile communication terminal, control data for receiving a retransmission message may be input (S455). That is, <Forwarding: Yes only: 0100000001: 0100000002: 0100000003> is inserted (S460) to transmit a message (S440). 0100000001, 0100000002, and 0100000003 are the phone numbers of A, B, and B, members of the electronic team.

When the vice-chairman who has received the message from the team leader retransmits the message, if he attempts to resend by entering 0100000008, the definition phone number that is a team member of the mechanical team, the vice-chairman's mobile communication terminal is set to <Forwarding: Yes only: 0100000001: 0100000002: 0100000003>. Since 0100000008 does not exist, it is determined that the message cannot be transmitted to 0100000008 and the message is not resent.

Therefore, according to one embodiment of the present invention, it is possible to control the retransmission of the message by distinguishing the mobile communication terminal capable of receiving the retransmitted message.

In addition, according to another embodiment of the present invention, it is possible to control the retransmission of the message by distinguishing the mobile communication terminal that can not receive the message. In the above example, if the team leader instructs the party to prepare a party to celebrate A's birthday, one of the electronic team members, the message may not be resent to A.

Therefore, the team leader inputs the identification number of the mobile communication terminal of the party that can not receive the retransmission message in the message (S445). Accordingly, the message in which <Forwarding: No: 0100000001> is inserted (S450) is transmitted to the mobile communication terminal of the assistant team leader (S440). If the vice-chairman attempts to resend the message to 0100000001, 0100000002, 0100000003, the vice-chairman determines that the message cannot be resent to 0100000001 and does not perform the retransmission of the message. That is, according to an embodiment of the present invention, it is possible to control the retransmission of the message by distinguishing the mobile communication terminal that can not receive the retransmitted message.

4C and 4D are flowcharts illustrating a message transmission method of a message transmission apparatus according to an embodiment of the present invention.

First, referring to FIG. 4C, the message transmission device according to an embodiment of the present invention generates a message (S470).

In FIG. 4C, the message transmission device may be either the message transmission server or the MMSC described with reference to FIG. 3B. That is, a message is generated that includes information such as weather, weather, securities, etc., rather than a message prepared by a user's input.

The message transmission device may determine whether the generated message corresponds to the paid information service (S472).

If it is determined that the pay information service, the control data is inserted (S474). The control data corresponds to data for preventing unauthorized transmission of a message corresponding to the paid information service in another mobile communication terminal period.

However, if it is set by the operator of the message transmission apparatus to insert the control data prohibiting retransmission collectively, step S472 described above is not performed, it is possible to insert the control data in the message in all messages. In addition, the determining of the paid information service may be replaced by determining whether the copyright is protected, and whether the copyright is protected may be determined based on a standard set by the transmission apparatus operator in advance. That is, when the stock information provided by the "Ghana" securities company and the copyright should be protected by the contract with the securities company, the control data insertion unit may insert the control data.

Thereafter, when the process proceeds directly from step S472 to step S476, the message transmitting apparatus transmits a message in which control data is not inserted.

However, when the process proceeds from step S474 to step S476, a message in which control data is inserted is transmitted.

The process of transmitting a message by the message transmitter is different from that of the MMSC and the message transmission server. That is, in the case of MMSC, it is possible to transmit to the transmitting mobile communication terminal via the base station directly through the exchange. In the case of a message transmission server interworking with the exchange through a separate IP communication network, the message is transmitted through the IP communication network, the exchange and the base station. Is transmitted to the receiving mobile communication terminal.

Referring to FIG. 4D, a message transmission device according to another embodiment of the present invention receives a message through a communication network. As mentioned in FIG. 4C, the message transmission device may be either the message transmission server or the MMSC described in FIG. 3B.

However, if the message transmission device is MMSC, the message transmitted from the transmitting mobile communication terminal can be transmitted through the mobile communication network. If the message transmission device corresponds to the message transmission server, the PC, notebook, PCA, etc. Receive a message through the communication terminal.

The message transmission device that receives the message determines whether the message includes control data. Since the control data is inserted according to a predetermined criterion, the message transmission apparatus may determine whether the control data is included. For example, as described with reference to FIG. 2, it is determined whether a <Fowording> item is included in the service parameter area.

If the control data exists, the control proceeds to step S486 to transmit the message without inserting the control data separately. That is, when the control data is present, as shown in FIGS. 4A and 4B, various control data are inserted, and thus, separate control data is not inserted.

However, if it is determined in step S482 that control data does not exist in the message, control data is inserted. However, it may be determined whether control data is inserted by querying a transmitting mobile communication terminal or a communication terminal such as a PC, a notebook computer, or a PCA whether to insert control data after step 482.

In step S486, the message in which the control data is inserted is transmitted. Since the process of transmitting the message has been described above with reference to FIG. 4C, it will be omitted.

5 is a diagram illustrating a process of transmitting a message according to an embodiment of the present invention through a mobile communication network.

In FIG. 5, ME 1 is a transmitting mobile communication terminal 300, MSC 500 is a switching center, MMSC 510 is a multimedia message service center, and ME 2 600 is a receiving mobile communication. The terminal, ME 3 (530) refers to another mobile communication terminal.

MSC 500 is a wired / wireless digital switch that provides wired communication, wireless communication and mobile communication functions. It is a network component that performs pivotal functions in mobile communication networks. Location registration procedure, handoff procedure processing and interworking function with other network.

In FIG. 5, the MMSC 500 is referred to for convenience of description, but the MMSC 500 may be a generic name of a server for transmitting and receiving a multimedia message service, and may be a generic name of a server including the message transmission server described with reference to FIG. 3B. In this case, it does not mean only one physical server, but can be defined as a combination of a series of servers for transmitting and receiving a multimedia message service.

The MMSC 510 receives and stores a message from the ME 1 300 and performs a caching function to allow the receiving terminal 600 to access the MMSC 510 to receive a message. In addition, it performs pre-paid, reply charging, message blocking, and integrated messaging functions through interworking with VMS (Voice Mail Sever), SMSC (Short Message Service Center) and external email servers.

Referring to FIG. 5, the ME 1 300 creates a multimedia message in which <Forwarding: Yes> or <Forwarding: NO> is inserted. Although FIG. 5 shows that a multimedia message is created in ME 1, it is obvious that a message can be created through a communication terminal such as a general PC.

The created multimedia message is uploaded to the MMSC 510 through the exchange 500 or through an IP communication network. The MMSC 510 stores the multimedia message and transmits a short message indicating that the multimedia message has arrived to the ME 2 600 through an SMSC (Short Message Center) interworking with the MMSC 510. Since the short message transmitted includes the MMSC 510 connection number, the ME 2 600 can be connected to the MMSC 510.

The ME 2 600 connected to the MMSC 510 downloads the multimedia message uploaded by the ME 1 300. The downloaded multimedia message is stored in the ME 2 600 and displayed.

After checking the displayed multimedia message, the user of the ME 2 600 attempts to retransmit the multimedia message to another mobile communication terminal ME 3 530 (S540). That is, the ME 2 600 receives a command for transmitting the multimedia message received from the user of the ME 2 600 to the ME 3 530. The ME 2 600 does not directly perform the transfer command but transmits the original. It is determined whether retransmission is allowed from the user of ME 1 (300). This will be described later in more detail with reference to FIGS. 6 and 7.

That is, the ME 2 600 determines whether the <Forwarding> parameter included in the service parameter area of the multimedia message is Yes or No (S550). If <Forwarding: No>, since retransmission is not allowed, a retransmission impossible screen is output to the display unit of the ME 2 600 (S570).

However, in the case of <Forwarding: Yes>, since retransmission is allowed, the multimedia message stored in the ME 2 600 is uploaded to the MMSC 510 (S560). The multimedia message received from the ME 1 300 may be uploaded by you, or the edited multimedia message may be uploaded to the MMSC 510 through an editing process such as rewriting text or changing background music.

The MMSC 510 stores the multimedia message (S580). The MMSC 510 transmits the stored multimedia message to the ME 3.

6 is a diagram illustrating a configuration of a receiving mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 6, the receiving mobile communication terminal 600 includes an antenna 610, an RF unit 620, a baseband processor 640, and an input unit 670. Like the transmitting mobile communication terminal 300 described with reference to FIG. 3, the receiving mobile communication terminal 600 may further include a display unit, a speaker, a camera, etc., and thus description thereof will be omitted.

In addition, the antenna 610 also plays the same role as the antenna 310 of the transmitting mobile communication terminal 300.

The RF unit 620 of FIG. 6 includes a message receiver 635 and a message transmitter 630. Since it includes one antenna, data to be transmitted and received is transmitted and received through the same antenna, and thus it is necessary to distinguish it, which is performed by a duplexer (not shown). The duplexer separates the transmitted / received signals to prevent cross talk of data or data.

That is, as described with reference to FIG. 5, when the multimedia message is downloaded from the MMSC 510, the received data is transferred to the message receiver 635 by the duplexer and subjected to baseband processing. On the other hand, the multimedia message that is baseband processed and wirelessly transmitted to the ME 3 may be wirelessly transmitted through the antenna without being leaked to the message receiver by being input to the message transmitter 630 and through the duplexer.

The message received by the message receiver 635 is input to the baseband processor 640, displayed on the screen unit, and stored in the storage unit 600. As described with reference to FIG. 3, the storage unit 600 may store contents and messages 611 to 669.

The message generator 651 generates a message to be transmitted to another mobile communication terminal according to the input received from the input unit 670. In this case, a part of the message stored in the storage unit 660 is transmitted from the user to another mobile communication terminal. You may be given a command to do so.

In this case, when the stored message is a message transmitted from ME 1 described with reference to FIG. 3, the message is retransmitted, and therefore, it is first determined whether retransmission is allowed.

Accordingly, the retransmission determining unit 659 reads the <Forwarding> parameter included in the multimedia message and determines whether the message is Yes or No. If No, the message is not sent to the message sender. Therefore, the message is stored only in the receiving mobile communication terminal 600 and is not distributed by retransmitting to another mobile communication terminal.

7 is a flowchart illustrating a procedure of retransmitting a message of a receiving mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 7, the receiving mobile communication terminal 600 receives a multimedia message (S700).

The received multimedia message is attempted to be retransmitted to another mobile communication terminal through the retransmission menu after being received and displayed or stored in the storage unit 660 and then read from the storage unit 660 after a predetermined time has elapsed. Retransmission may be attempted at. Alternatively, a picture may be deleted from the content included in the multimedia message, for example, a picture, text or background music, and the rest may be retransmitted. The retransmission attempt may be performed by receiving a retransmission command from the user of the receiving mobile communication terminal 600 (S710).

The receiving mobile communication terminal 600 first determines whether a <Forwarding> parameter exists (S270). If the <Forwarding> parameter does not exist, the multimedia message is allowed to be retransmitted as in the prior art, and the flow proceeds to step S740 to retransmit the multimedia message (step 740). Even if <Forwarding> exists, even if <Forwarding: Yes>, the user of the transmitting mobile communication terminal 300 permits retransmission and transmits the multimedia message, and proceeds to step S740 to transmit the multimedia message (step S740).

However, if <Forwarding: No> is not allowed, the multimedia message retransmission is not allowed, so the multimedia retransmission failure is notified and the multimedia message retransmission is terminated.

According to another embodiment of the present invention, when retransmission parameters are inserted for each content included in the multimedia message, in the step S710, the content that cannot be retransmitted is edited so that the retransmission of the multimedia message is performed when a retransmission command is input. The process may proceed to step S740. In other words, assuming that a multimedia message contains three types of content: photo, text, and background music, if <Pictuer.jpg: Forwarding: No> is inserted only for the picture, the picture is deleted and only the text and background music are inserted. This multimedia message edited to be present can be processed to enable retransmission.

8 is a diagram illustrating a retransmission determination and a screen of a receiving mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 8, various messages are stored in the message archive 800 of the received message. If the user selects “1. Winter”, the menus such as 1. Reply, 2.Forward, and 3.Number are displayed on the screen. If you select "2. Forward", the message is output on the screen (805) and the message can be edited on the screen.

When editing is finished, a menu is selected. The menu includes a "forwarding" item, and the configuration of other menus may be different depending on a short message, a multimedia message, and a multimedia message in SMIL format.

If "Forwarding" is selected, the receiving mobile communication terminal determines whether the <Forwarding> parameter is Yes or No.

If <Forwarding: Yes>, message preparation continues because the message may be retransmitted to another mobile communication terminal. The receiving mobile communication terminal according to another embodiment of the present invention may output charging information such as information usage fee charged for retransmitting the corresponding message on the screen 815. When the user agrees to the billing information and selects the transmission, a screen 820 is output to input a phone number or an e-mail address of another mobile communication terminal to which the message is to be resent, and the message is retransmitted to the written address.

However, in the case of <Forwarding: No>, a notification message "The message cannot be retransmitted because retransmission is impossible" is output (803).

The method of the present invention as described above may be implemented in a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art that various modifications of the present invention without departing from the spirit and scope of the invention described in the claims below And can be changed.
