The present invention relates to a mobile communication supplementary service technology, and more particularly, to a call request calling service system and method having an effect of transmitting a multimedia message (eg, a text message).

In general, if the caller wants to answer the call from the called party, the caller then hangs up immediately if the caller wants to ring and leaves the missed call on the called party's side so that the called party can confirm the call and call the calling party. Often it is induced. In this case, the sender side and the receiver side occupy the actual wired and wireless resources, but there is a problem that the wired and wireless communication operators can not charge due to the incomplete call.

In addition, it is not a problem when the receiver side is well aware of the caller side, but the telephone number is frequently reversed for confirmation despite the unknown telephone number. In this case, since the receiver side does not know the nature of the missed incoming call, there is a problem in that a telephone call is made unnecessarily by making a call to the caller side to confirm.

In order to solve the above problems, Korean Patent Application No. 2003-44173 has the title of "Method and system for providing a service that can send a text message with a call request", if the recipient is absent a separate text message The present invention has disclosed a method and system for allowing a simple request to be made simply by making a call request without transmitting a call, and allowing a recipient to selectively receive a call according to the request.

This prior art uses the input string "** Relevant to today's contract ... ## 0112341757" (** denotes the start delimiter, the message "Relevant to today's contract ..." After ## is the end delimiter and 0112341757 is the called number, press the "Call" button or the "Send" button, the called terminal will ring with a ringtone on the screen and the message entered at the calling terminal and the calling terminal's telephone Make sure the number is displayed.

However, such a prior art has a problem that its utility value is significantly degraded due to a user who is hard to send the above-described character string or annoying user.

Accordingly, it is an object of the present invention to provide a call request call service system and method capable of inducing a call from a caller side to a called party by effecting a text message transmission with a simple key input.

To this end, the call request call service system for transmitting a text message for a call request from the calling terminal to the called terminal according to the present invention, by receiving a call request character combination string from the calling terminal to identify the identification code, number combination and the incoming call A switch for translating to a phone number of the terminal and transmitting the text message converted from the identification code and the number combination to the called terminal; And an SMS center for converting the identification code and the number combination according to the translation result into a text message.

In addition, a call request call service method for transmitting a text message for a call request from a calling terminal to a called terminal according to the present invention comprises the steps of: (a) receiving a call request including a character combination string; (b) interpreting the character combination string and distinguishing the identification code, the number combination, and the telephone number of the called terminal; (c) converting the identification code and number combination into a text message; And (d) transmitting the converted text message to the called terminal.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments. Like reference numerals refer to like or similar elements throughout the drawings.

1 is a block diagram showing a call request call service system according to the present invention.

As shown in Fig. 1, the system includes an originating terminal 100 for inducing a call by transmitting a text message through a simple key input, and an incoming call receiving the text message and displaying it on the screen together with the calling terminal telephone number. The terminal 600, the home network switch 200 for translating a combination of identification codes and numbers requested from the calling terminal 100, and the HLR 300 for inquiring the position of the called terminal based on the called terminal number according to the translation result. ), An SMS center 400 for converting an identification code and a number combination according to a translation result into a text message, and a visited network exchanger 500 for transmitting the converted text message to a destination terminal.

The home network exchanger 200 receives and interprets the call request character combination string transmitted from the calling terminal 100. As a result of the analysis, the home network switch 200 determines the additional service type through the identification code of the call request character combination string, and then transmits the call request character combination string to the SMS center 400.

The SMS center 400 receives the call request text combination string from the home network switch 200 and converts the call request text combination string into a text message according to an identification code and a predetermined number of digits. Examples of this identification code are special characters such as "*" and "#", or a combination of such special characters. The predetermined number of digits is at least one or more digits, and it is particularly appropriate to set the digits so that semantic induction is easily possible. For example, "82 (call me quickly)", "04 (I love you forever)" and "77 (good luck)" are suitable as these numbers. In addition, the SMS center 400 transmits the telephone number of the called terminal 600 to the HLR 300 of the call request character combination string to receive the position of the called terminal 600 from the HLR 300. In addition, the SMS center 400 transmits the phone number of the called terminal 600 to the visited network switch 500 together with the converted text message, so that the called terminal 600 receives the converted text message.

2 is a flowchart illustrating a call request calling service method according to the present invention.

Referring to FIG. 2, first, the calling terminal 100 receives an identifier, a number of predetermined digits, and a phone number of the called terminal 600, and then receives a call request key button such as "call" or "send". (S210). For example, assuming that the telephone number of the calling terminal 100 is "011-754-1111", and a character combination string such as "## 820117540861" is received, "##" corresponds to an identifier, and "82" corresponds to an identifier. Corresponds to the number of predetermined digits representing the message to be delivered, and "0117540861" corresponds to the telephone number of the called terminal 600. In this case, unlike in the prior art, there is no need to select a specific mode (eg, the Call with SMS mode for inputting a character string in the prior art), and there is no need to directly input a character string corresponding to "82". .

As the call request key button described above, the home network switch 200 receives the above-described character combination string.

The home network exchanger 200 interprets the character combination string, determines the corresponding supplementary service type through the identification code, and then transmits the character combination string to the mobile communication network supplementary service component related to the supplementary service, that is, the SMS center 400. Transfer (S220).

The SMS center 400 recognizes the call request call service according to the present invention through this identification code (S230). In this case, the SMS center 400 may recognize that the call request call service is provided through an identification code and a number of digits representing a message to be transmitted.

Accordingly, the SMS center 400 distinguishes the number of the predetermined digits from the telephone number of the called terminal 600 in the above-described character combination column, and converts the number of the predetermined digits into a text message (S240). The location of the called terminal 600 is determined from the HLR 300 through the phone number of the terminal 600 (S250). At this time, in step S240, a number of predetermined digits and a text message corresponding to the number may be stored in a mapping table in advance, and a method of converting each request may be used.

Thereafter, the SMS center 400 transmits the converted text message to the destination terminal 600 through the visited network switch 500 (S260). Then, the phone number of the calling terminal 100 is displayed on the screen of the called terminal 600 together with the corresponding text message. By doing this, you can simply call the call request by sending a text message.

3 is an exemplary diagram to which a call request call service according to the present invention is applied.

As shown in FIG. 3 (a), when the character combination string "## 820117540861" is input to the initial screen of the calling terminal 100 in a manner similar to a call request, and a call request key button such as "call" or "send" is pressed. As shown in (b) of FIG. 3, it may be seen that “Please call as soon as possible 011-754-1111” is displayed on the screen of the called terminal 600.

While the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will recognize that various modifications or changes can be made without departing from the spirit and scope of the invention.

As described in detail above, according to the present invention, by inducing subscribers at low rates such as text rates, the call request text is easily sent to the called party, and the called party makes a call, thereby eliminating incomplete calls and improving the text message transmission effect. There is an effect that can be made.

In addition, according to the present invention, it is possible to induce a call by sending a text message to the called party with a simple key input, there is an effect of eliminating the inconvenience on the sender side.
