The present invention relates to a method and a system for providing a service that can transmit a text message when a call is requested. More particularly, when a call is made from an originating mobile communication terminal to a terminating mobile communication terminal, the information to be delivered by the user is provided. The present invention relates to a method and system for providing a service for displaying a text message at the same time that a ring tone is output from an incoming mobile communication terminal when the text message is edited and transmitted together.

As computer, electronic, and communication technologies have made rapid progress, various wireless communication services using wireless networks have been provided. The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, which can provide a service regardless of time and place. In addition, while providing a text message service to complement the voice call service, the text message service is a sensational popularity among the younger generation. In recent years, a wireless Internet service has been introduced to provide an Internet communication service to a user of a mobile communication terminal through a wireless communication network.

Accordingly, the subscribers of the mobile communication service can freely move and talk with the other party anytime and anywhere using the wireless communication service, and also provide various information necessary for life through the wireless Internet service, such as news, weather, sports, securities, Exchange rates or traffic information may be provided in various forms such as text, voice, or image.

In addition, due to the rapid dissemination of mobile communication terminals, mobile communication terminals have become an essential means of communication in modern life, such as a considerable amount of communication occurring in human relationships through mobile communication terminals. Accordingly, customers of mobile communication services are requesting various additional services in addition to basic call services, and mobile communication service providers are developing new additional services to meet the needs of these customers.

Among the additional services developed based on the needs of these customers, there is a caller ID service. The caller display service is a service that displays a caller's telephone number on the receiver's mobile phone LCD screen so that the caller's telephone number missed can be checked. That is, when the calling mobile terminal makes a call to the called mobile terminal, the calling mobile terminal transmits a call connection request signal including its own telephone number and the telephone number of the called mobile terminal to the mobile switching center through the wireless access network. Request a call. The mobile switching center determines the location of the incoming mobile terminal through the home location register, and then transmits the incoming signal including the telephone number of the calling mobile terminal to the destination mobile terminal. Therefore, the incoming mobile communication terminal outputs a ringing tone when the incoming signal is received and displays the telephone number of the outgoing mobile communication terminal.

The conventional caller ID service provided by the above process simply displays the phone number on the receiving mobile terminal receiving the call. Therefore, when the recipient remembers the displayed phone number, it is easy to determine who the caller is. In some cases, for example, a call may be answered without knowing that the call is a disadvantage for the user.

Of course, when the incoming phone number corresponds to the stored phone number while the phone number and name for the callable person are stored in the incoming mobile terminal, the incoming mobile terminal may enter the corresponding phone number. It also recognizes the sender by displaying the stored name. However, since there is a limitation in entering and storing a telephone number in the terminating mobile terminal, in most cases, only the incoming telephone number is displayed on the terminating mobile terminal.

To compensate for this, the caller registers his / her name or nickname with the phone number in advance, and when the caller makes a call, the caller automatically displays his / her name or nickname. There is provided a caller nickname display service that gives a confidence in the phone call.

1 is a block diagram illustrating a system for providing a caller nickname indication service.

The caller nickname indication service system includes an outgoing mobile communication terminal 110, a terminating mobile communication terminal 112, a base station and a mobile switching center 114, a home location register (HLR) 116, and a customer oriented information system (COIS) 118. Caller nickname display service server 120, and the like.

When the calling mobile communication terminal 110 makes a call to the called mobile communication terminal 112, the user's telephone number and the called mobile communication terminal are registered in the state in which the calling mobile communication terminal 110 registers a name or nickname in advance. The call connection request signal including the telephone number of the call is transmitted to the mobile switching center 114 to request a call. The mobile switching center 114 determines the location of the incoming mobile communication terminal 112 via the HLR 116, and then queries the nickname. The HLR 116 receives the subscription information of the originating mobile communication terminal 110 from the COIS 118, queries the nickname of the caller nick display service server 120, and the COIS 118 from the caller nickname display service server 120. The subscription information is received from the corresponding nickname information is delivered to the HLR (116). The HLR 116 transmits the received nickname information to the mobile switching center 114 and transmits an incoming signal including the phone number and nickname information of the originating mobile communication terminal 110 to the destination mobile communication terminal 112. Therefore, the incoming mobile communication terminal outputs a ringing tone when the incoming signal is received and displays the telephone number and nickname of the outgoing mobile communication terminal. Such nicknames should be registered in advance through wired and wireless Internet.

The caller nickname display service has the advantage of displaying a nickname rather than a simple phone number, compared to a simple caller display service. However, the nickname must be registered in advance and the uniform nickname set by the user is delivered in advance. . In addition, from a system perspective, since a separate network node called the caller nickname display service server 120 is required in the existing system, there is a problem that a separate investment cost is generated.

In order to solve the above problems, the present invention, when making a call from the outgoing mobile communication terminal to the destination mobile communication terminal, the ringtone is output from the destination mobile communication terminal when the contents to be transmitted and edited together in a text message It is an object of the present invention to provide a method and system for providing a service for displaying a text message at the same time.

3 is a flowchart illustrating a process of providing a CSMS service according to an exemplary embodiment of the present invention.

First, when the outgoing mobile communication terminal 210 performs a call attempt, it is determined whether the operation mode of the outgoing mobile communication terminal 210 is set to the CSMS mode (S300). If the operation mode of the outgoing mobile communication terminal 210 is not set to the CSMS mode, since a character other than a number cannot be input when performing a call attempt, the outgoing mobile communication according to the preferred embodiment of the present invention is used. The operation mode of the terminal 210 should be set to the CSMS mode. The method for setting the outgoing mobile terminal 210 to the CSMS mode is automatically performed when the user changes the mode using the mode change menu of the outgoing mobile terminal 210 or inputs the start separator ** as described above. The method of setting to the CSMS mode may be possible.

As a result of determination, when the outgoing mobile communication terminal 210 is set to the CSMS mode, an input string is input to the outgoing mobile communication terminal 210 to transmit a call request signal including the input string to the base station transmitter 222 (S302). ).

The call request signal is transmitted to the mobile switching center 230 through the base station controller 224, and the mobile switching center 230 analyzes an input string included in the call request signal (S304). At this time, the mobile switching center 230 analyzes the message between the start delimiter ** and the end delimiter ## as the text data and the number after the end delimiter ## as the called number data.

The mobile switching center 230 establishes a call path after confirming the location of the incoming mobile communication terminal 212 by transmitting the called number data included in the analyzed input string to the home location register 240 (S306).

When the call path is established, the mobile switching center 230 transmits an incoming signal including the telephone number of the calling mobile communication terminal 210 and the message data included in the input string through the base station controller 224 and the base station transmitter. 212) (S308).

The incoming mobile communication terminal 212 displays the telephone number and message data of the outgoing mobile communication terminal 210 on the screen while outputting a ringing sound (S310).

The microprocessor of the incoming mobile communication terminal 212 playing the ring tone checks whether a key value or a signal related to a call connection is input (S312). Here, the input of a signal related to a call connection means that the flip is opened in the case of a flip-type terminal and the call is connected. In the case of a folder-type terminal, the folded caller and the receiver are fixed. It goes beyond the interval, meaning the call is connected.

When it is determined that a key value or a signal related to a call connection is input, a call connection signal is generated and transmitted to the outgoing mobile terminal 210 through the mobile communication network, and the outgoing mobile terminal 210 and the incoming mobile communication terminal 212. The call between the two proceeds (S314).

On the other hand, when the mode of the outgoing mobile communication terminal 210 is not set to the CSMS mode, the call proceeds as in the normal call. That is, when the incoming mobile number is input from the outgoing mobile terminal 210, the process proceeds in a form in which the ringing sound is output from the incoming mobile terminal 212 (S316).

4 is a diagram illustrating an example of a result of transmitting a text message when a call is requested using a CSMS service according to an exemplary embodiment of the present invention.
